The Vision C++ interface kit is supplied in source
code form. You are encouraged to modify that source code to suit your
needs. The kit has been tested using default compilation options under
the following combinations of operating systems and compilers:
| Operating System | Compiler Version |
|---|---|
| HP-UX/10.01 | HP C++ Version A.10.01 |
| IBM AIX/4.2 | IBM C Set ++ For AIX <IP_ADDRESS> |
| Sun Solaris/5.5 | Sun Sparcompiler C++ 4.1 |
| Microsoft Windows/NT 3.51 | Microsoft Visual C++ 4.2 |
The functionality of the Vision C++ interface kit is also available in COM form
using the VAccess COM objects.
| Class Name | Class Description |
| VSockets | A class that hides a number of operating system dependencies in the use of sockets, including the need to explicitly initialize the socket library in Windows environments. Your application must create exactly one instance of this class in order to function. That instance should be created when your application starts and destroyed when your application terminates. |
| VConnection | A class that provides connections to Vision. It can launch new Vision sessions using the remote execution daemon or connect to existing Vision servers running at known port addresses. For both kinds of connections, this class's 'submit' member function allows you to receive the output generated by any Vision expression you specify. This class also provides member functions to process Vision include files, execute a Vision expression without returning any output and obtain the value of an item for an entity in your Vision data base. To use Vision, you need to create one instance of this class although you can create more if your application needs to talk to more than one Vision session at a time. |
| VExtractWS | This class encapsulates array based retrieval of Vision data using Vision's ExtractWS interface. Your application can create as many instances of this class as it needs. |
| VString | This class implements variable length character strings. An instance of this class is used to receive the output returned by VConnection's 'submit' member function. You can also use this class as a tool that does the book-keeping of string management. |
| VDatum | This class implements a variant type capable of holding numeric, string, or NA data. When you retrieve data using the VExtractWS interface to Vision, your data is returned as an array of VDatum objects. |
| VDatumArray | This class implements a variably sized array of VDatum objects. An instance of this class is used to receive data returned by VExtractWS based data requests. You can create and use as many instances of this class as your application needs. |
The remainder of this section illustrates how these classes are used to access Vision. That illustration begins with the include files needed to access the definitions of these classes.
Every application source code file you write that uses the classes defined
in the Vision C++ interface kit needs to include the header files that
define those classes. The class descriptions given in the reference section
of this document supply the names of those files. Every file that includes
one of those class definition files should include VStdLib.h before
it includes any of the interface kit's class definition files. The example
illustrated in this section needs the following files:
#include "VStdLib.h"
#include "VSockets.h"
#include "VConnection.h"
#include "VExtractWS.h"
Note that because VStdLib.h already includes a number of standard
C++ header files, you may not need to include them again yourself, although
there is generally no harm done if you do.
The example illustrating this section does most of its work in a classic UNIX style main program although the techniques are applicable to GUI based Windows style programs as well.
As noted in the introduction to this section, every application that
uses the Vision C++ interface kit needs to create a single instance of
class VSockets when it starts. The first few lines of this main
program create that instance and test to make certain that it was properly
initialized:
int main (int argc, char* argv[])
{
VSockets SocketSubsystem (VTrue);
if (!SocketSubsystem.initialized ())
{
fprintf (stderr, "Socket Initialization Failed!!\n");
return -1;
}
// Do something useful here...
}
The VSockets class encapsulates the operating system dependencies
associated with using sockets. One of those dependencies is the need to
make an explicit initialization call when using the Windows based implementation
of the socket libraries. The VTrue passed to the VSockets constructor
asks the constructor to make that call. It also ultimately asks the destructor
for this VSockets object to make the corresponding de-initialization
call. If your application is already making those calls, either directly
or because of some other class library it is using, you should pass VFalse
to the VSockets constructor and NOT perform the SocketSubsystem.initialized()
test shown above.
Once your instance of VSockets has been created, you can use
it to create one or more Vision sessions or connect to one or more Vision
servers. Most applications, including the one illustrated here, only need
one connection to do their work, but you can create as many connections
as you need. The following statement creates a
VConnection object:
VConnection myConnection (SocketSubsystem);
Creating a VConnection object does not actually connect you to a
Vision session. To do that, you need to call either the rexec or
connectVConnection
member function.
The rexec member function uses the remote execution daemon to
start a private Vision session for your use:
char iMessageBuffer[256];
if (!myConnection.rexec (
iMessageBuffer, sizeof (iMessageBuffer),
Host (argc, argv),
User (argc, argv),
Password (argc, argv),
Command (argc, argv)
)
)
{
fprintf (
stderr,
"Connection Attempt Failed!!\nReason: %s",
iMessageBuffer
);
return -1;
}
This function accepts six arguments, the first two of which supply a buffer
which will be filled with an error message if your session could not be
started. The next three arguments specify the host, user name, and password
used to create your session. The final argument is optional -- it supplies
the command string used to start your batchvision session. If you do not
supply this argument, the interface kit will run /vision/bin/batchvision
with no arguments. The Host, User, Password, and Command
functions called here are not part of the interface kit -- they are simply
syntactically valid placeholders for the argument values you must supply.
It is your responsibility to supply those values in whatever way is appropriate.
If the rexec member function succeeds, it returns a non-zero value. If it fails it returns 0 and places a string in the message buffer you supplied indicating the reason for its failure.
The connect member function is the other way to establish a connection
to a Vision session:
if (!myConnection.connect (Host (argc, argv), 8001))
{
fprintf (stderr, "Connection Attempt Failed!!\n");
return -1;
}
This function accepts two arguments -- the name of a host and the number
of a port. It expects to find a Vision server listening for connections
at the specified port on the specified host. In the case illustrated here,
the host is obtained from the command line and the port is hardwired to
port 8001. There is nothing magic about this number -- you or your Vision
administrator decide what it will be when the service is created.
Like the rexec member function, the connect member function returns a non-zero value when it succeeds and zero when it fails.
You can call either or both of these member functions as often as you need or care to for a given connection. Each call disconnects the current Vision session if one was established and creates or connects to a new session based on the argument values you supply.
Once you have connected your VConnection object to a Vision session,
you can use it to run Vision expressions and retrieve data from Vision.
The 'submit' VConnection member function allows you to run an arbitrary
Vision expression and collect the output it generates. For example:
VString iBalanceSheet;
if (myConnection.submit (
iBalanceSheet,
"Named Company IBM balanceSheet"
)
) printf (
"Balance Sheet:\n%s\n", (char const*)iBalanceSheet
);
requests a balance sheet from Vision and writes it to standard output.
The submit member function expects two required arguments -- an instance of a VString object which will receive the output generated by your Vision request and a null-terminated character string containing the text of that request. The submit member function returns a non-zero value when it succeeds and zero when it fails.
As noted earlier, the VString class is one of three helper classes provided in the Vision C++ interface kit used to receive results from Vision. As illustrated here in the call to printf, VString objects can be used anywhere a 'const' C++ string can be used. In most cases, the compiler makes the necessary conversion automatically; however, in this case, the compiler does not know what type of value to pass to printf so an explicit cast is required.
In addition to its required arguments, the submit member function accepts four optional arguments -- two that specify the global date and currency applicable to your request and two that are helpful in collecting very large and very small quantities of output.
The first and second optional arguments to submit (its fourth
and fifth actual arguments) specify the date as of which to run your request
and the default currency to which to convert monetary values when processing
that request. Both arguments are specified as strings and can be null (i.e.,
(char const*)0) to select your system's default value for the parameter.
For example:
VString iBalanceSheet;
if (myConnection.submit (
iBalanceSheet,
"Named Company IBM balanceSheet",
(char const*)0,
"CHF"
)
) printf (
"Balance Sheet:\n%s\n", (char const*)iBalanceSheet
);
requests IBM's balance sheet reported in Swiss Francs while:
VString iBalanceSheet;
if (myConnection.submit (
iBalanceSheet,
"Named Company IBM balanceSheet",
"93"
)
) printf (
"Balance Sheet:\n%s\n", (char const*)iBalanceSheet
);
requests IBM's balance sheet as of 1993, and:
VString iBalanceSheet;
if (myConnection.submit (
iBalanceSheet,
"Named Company IBM balanceSheet",
"93",
"CHF"
)
) printf (
"Balance Sheet:\n%s\n", (char const*)iBalanceSheet
);
requests IBM's balance sheet as of 1993 reported in Swiss Francs.
The fifth and sixth arguments to submit specify, respectively, how much buffer space to initially allocate for the reply to your request and by how much to grow that space when the current allocation proves insufficient. Both arguments default to 4096 bytes. If you know in advance that you are expecting a very large or a very small amount of output, you can pass more appropriate values for these optional parameters.
The submit member function is not the only way to interact with Vision using a VConnection object. The execute member function is an alternative to submit if you do not care about the output generated by your request. The execute member function takes one required argument -- a null terminated character string containing the Vision expression you want executed -- and two optional arguments -- the global date and currency applicable to that expression. Like the submit member function, execute returns a non-zero value if it was able to run your Vision expression and zero if it could not.
The VConnection class also provides include member functions to process Vision include files. These functions read and execute a file of Vision code resident on the system where your Vision session is running. Both return a non-zero value if they were able to ask Vision to process the file and zero if they could not.
Finally, the VConnection class provides the getValue member
functions. These member functions access the value of an item for an entity
in your Vision data base. For example:
double iReal;
if (myConnection.getValue (iReal, "Company", "IBM", "sales"))
Display (iReal);
else printf ("Could not get IBM's sales!\n");
returns the value of IBM's sales as of the current date, expressed in the
default currency for your data base. The getValue function is overloaded
based on the C++ data type you want returned. The overload used here returns
the item's value as a real number. Other versions of this member function
return their value as an integer, a VString, and a VDatum -- a Vision C++
interface kit data type discussed in greater detail below. All of the getValue
members return a non-zero value if they were able to submit your request
to Vision and convert its result to the result type required by the overloaded
member you called.
The getValue member functions also accept two optional arguments
that specify the date and currency to use when retrieving the item. For
example:
if (myConnection.getValue (
iReal, "Company", "IBM", "sales", "93"
)
) Display (iReal);
else printf ("Could not get IBM's sales!\n");
accesses IBM's sales as of 1993 while:
if (myConnection.getValue (
iReal, "Company", "IBM", "sales", 0, "CHF"
)
) Display (iReal);
else printf ("Could not get IBM's sales!\n");
accesses IBM's most recent sales expressed in Swiss Francs and:
if (myConnection.getValue (
iReal, "Company", "IBM", "sales", "93", "CHF"
)
) Display (iReal);
else printf ("Could not get IBM's sales!\n");
accesses IBM's sales as of 1993 expressed in Swiss Francs.
The VConnection class provides a relatively unstructured interface
to
Vision. The VDatumArray and VExtractWS classes provide a
structured interface. In particular, the VExtractWS class provides
you with access to the Interface ExtractWS Vision ToolKit for retrieving
array structured data from Vision. The following Vision C++ interface kit
code creates a VExtractWS object initialized to request a 4 row by 3 column
entity by item array of data:
VExtractWS iExtractWS1 (&myConnection);
iExtractWS1
.setOrientationToEI ()
.setDelimiterTo ("##")
.setEntityTypeTo ("Security")
.addEntity ("GM")
.addEntity ("IBM")
.addEntity ("HWP")
.addEntity ("XON")
.addItem ("name" , VDatumKind_String)
.addItem ("price" , VDatumKind_Real)
.addItem ("price@95", VDatumKind_Real)
;
The preceeding code fragment specifies the data you want to retrieve; the
following interface kit code actually gets it:
VDatumArray iDatumArray1;
if (iExtractWS1.run (iDatumArray1))
DisplayArray (iDatumArray1);
The DisplayArray function is not part of the interface kit -- it
is an example of a routine you would write to do something with the data
you retrieved. It might look like this:
void DisplayArray (VDatumArray const& myDataArray)
{
size_t rowCount = myDataArray.elementCount(0);
size_t colCount = myDataArray.elementCount(1);
for (unsigned int row = 0; row < rowCount; row++)
{
for (unsigned int col = 0; col < colCount; col++)
{
VDatum& iElement = myDataArray.element (row, col);
switch (iElement.kind ())
{
case VDatumKind_NA:
printf (
"Row %u, Col %u Is NA\n", row, col
);
break;
case VDatumKind_Integer:
printf (
"Row %u, Col %u Is The Integer %d\n",
row, col, (int)iElement
);
break;
case VDatumKind_Real:
printf (
"Row %u, Col %u Is The Real Number %g\n",
row, col, (double)iElement
);
break;
case VDatumKind_String:
printf (
"Row %u, Col %u Is The String <%s>\n",
row, col, (char const*)iElement
);
break;
default:
printf (
"Row %u, Col %u Has An Unrecognized Type\n",
row, col
);
break;
}
}
}
}
The run member function returns a non-zero value when it succeeds
and zero when it fails. When the call illustrated above succeeds, iDatumArray1
contains four rows -- one for each Security -- and three columns -- one
for each item -- specified in the calls that created iExtractWS1.
The items added to this extract workspace were added with data types. When you explicitly specify a data type with an item, the interface kit will store or convert the returned values for that item to the type you specify. If the item's value cannot be converted to that type, it will be stored as NA. In this case, the values in column 0 (the first column) will all be strings while the values in column 1 and 2 (the second and third columns) will be stored as real numbers (i.e., C++ type double) or NA. The item type is an optional argument to the addItem and setItemToVExtractWS member functions -- if it is omitted or specified as VDatumKind_NA, the Vision C++ interface kit will attempt to convert the item's value to a number if possible, returning the value as a string if and only if it isn't explicitly recognized as a Vision NA or cannot be converted to a numeric value.
You can modify the settings associated with a VExtractWS object
and re-run it. The following example adds an entity and an item to the
extract workspace object created above, changes its orientation to item
by entity, and re-runs it.
iExtractWS1
.setOrientationToIE ()
.addEntity ("ACD")
.addItem ("company compustat sales")
;
if (iExtractWS1.run (iDatumArray1))
DisplayArray (iDatumArray1);
printf ("\n");
When you re-use an extract workspace object, only your changes are transmitted
to Vision. You can request that all of the current settings in the workspace
be re-transmitted when you re-run the workspace. You do that by passing
a non-zero value as the value of the run member function's first
optional parameter:
if (iExtractWS1.run (iDatumArray1, VTrue))
DisplayArray (iDatumArray1);
printf ("\n");
You can create as many VExtractWS and VDatumArray objects
as your application needs. Each VExtractWS corresponds to a distinct ExtractWS
object in your Vision session that does not interfere with any other workspace
object. When you destroy one of your VExtractWS objects, the corresponding
remote object is also destroyed.
The following code creates and initializes a second workspace and uses
it to fill a second data array:
VExtractWS iExtractWS2 (&myConnection);
iExtractWS2
.setOrientationToET ()
.setColumnLabelsOn ()
.setRowLabelsOn ()
.setEntityTypeTo ("Security")
.setItemTo ("price", VDatumKind_Real)
.setEntityListTo ("GM, IBM, HWP, XON")
.addDate ("9601")
.addDate ("9512")
.addDate ("9511")
.addDate ("9510")
.addDate ("9509")
.addDate ("9508")
.addDate ("9507")
.addDate ("9506")
.addDate ("9505")
.addDate ("9504")
.addDate ("9503")
.addDate ("9502")
.addDate ("9501")
;
VDatumArray iDatumArray2;
if (iExtractWS2.run (iDatumArray2))
DisplayArray (iDatumArray2);
printf ("\n");
Note that this example also illustrates one of two alternate methods for
specifying an entity list. In this case, the entity list is specified as
a comma separated list of values. You can also use Vision's Interface ExtractWS
ability to generate the list dynamically as the following example illustrates:
VExtractWS iExtractWS3 (&myConnection);
iExtractWS3
.setOrientationToEI ()
.setColumnLabelsOn ()
.setScalarLabelOn ()
.setEntityTypeTo ("Security")
.setEntityTo ("IBM")
.setEntityListExpressionTo ("holdings")
.addItem ("account name" , VDatumKind_String)
.addItem ("shares" , VDatumKind_Real)
.addItem ("totalCost" , VDatumKind_Real)
.addItem ("totalMarketValue", VDatumKind_Real)
;
VDatumArray iDatumArray3 (2);
if (iExtractWS3.run (iDatumArray3))
DisplayArray (iDatumArray3);
printf ("\n");
In addition to possibly renaming the '.c' files, you may need to add one or more libraries to the list of run-time libraries with which you link your application. In all cases, these libraries provide support for the socket calls made by the classes included in the interface kit.

VArray<T>
Definition:
#include "VArray.h"
This class is a pure abstract class that cannot be instantiated directly. Its purpose in life is to provide the implementations of element type independent operations to the VArray class template. Primarily, those operations deal with setting and querying the size and shape of an array.
You can access a multi-dimensional array either multi-dimensionally or as a vector which linearizes the array in "row-major" order. The member functions defined in this class help you to construct and decode a linearized view of an array.

#include "VConnection.h"
VConnection objects support two strategies for accessing Vision. Their rexec member function uses the rexec service to start a Vision session while their 'connect' member function contacts an existing Vision server listening on a known port.
Both the rexec and connect member functions can be called multiple times. If an established connection exists when one of these member functions is called, it will be disconnected and replaced by the connection requested by the call, if possible.
However connected, all connection objects allow you to execute Vision expressions, process Vision include files, and obtain the value of an item for an entity in your Vision data base. The routines to do these things are described below and illustrated in the usage section of this document.
Construction/Destruction
VConnection (VSockets& iSocketManager); virtual ~VConnection ();
Remote Execution
int rexec ( char * pErrorMessageBuffer, size_t sErrorMessageBuffer, char const * pHostName, char const * pUserName, char const * pPassword, char const * pCommand = "/vision/bin/batchvision" );
Connections established using this member function support the full remote execution protocol. In particular, they return error messages using a separate channel and can be interrupted using the signal member function described below.
Connection
int connect (char const *pHostName, u_short xHostPort);
Disconnection
void disconnect ();
Request Execution
int submit ( VString& iReply, char const* pRequest, char const* pDate = 0, char const* pCurrency = 0, size_t sReplyBufferInitialAllocation = 4096, size_t sReplyBufferAllocationIncrement = 4096, ); int execute ( char const* pRequest, char const* pDate = 0, char const* pCurrency = 0 ); int include ( char const* pIncludeFileName ); int include ( char const* pIncludeFileName, VString& iIncludeReply );
The submit member function accepts four optional arguments two that specify the date and currency globally applicable to your request and two that tune the behavior of this routine when receiving very large or very small amounts of output.
The first and second optional arguments to submit specify the default date and currency to use when running your request. Both arguments are specified as strings and can be passed as null (i.e., (char const*)0) to select your system's default for the parameter.
This routine allocates a temporary buffer which it uses to collect a request's output. That buffer is grown as necessary. The third and fourth optional arguments to submit determine the initial size of that buffer as well as the amount by which it grows when it is full. If you anticipate a very large or very small amount of output for a given request, you can pass your own values for these arguments to make the collection of your output more efficient.
The execute member function is an alternative way to submit a Vision request for execution when you do not care about the output it returns. The execute member function accepts the same request submission parameters as submit -- a required request string and optional date and currency strings -- and returns a non-zero value when it succeeds and a zero when it fails.
The include member functions allow you to execute a file of Vision code. Both functions accept the path name of a file and ask your Vision session to read and execute that file. The path name must specify the name of a file accessible to the Vision session to which this VConnection is speaking. This member is overloaded -- the two parameter form of this member function allows you to inspect the output generated by your include file while the one parameter form quietly discards that output. Both forms return a non-zero value if they were able to submit the include request to Vision and zero if they could not.
Value Retrieval
int getValue ( VDatum& iResult, char const* pEntityType, char const* pEntity, char const* pItem, char const* pDate = 0, char const* pCurrency = 0 ); int getValue ( VString& iResult, char const* pEntityType, char const* pEntity, char const* pItem, char const* pDate = 0, char const* pCurrency = 0 ); int getValue ( double& iResult, char const* pEntityType, char const* pEntity, char const* pItem, char const* pDate = 0, char const* pCurrency = 0 ); int getValue ( int& iResult, char const* pEntityType, char const* pEntity, char const* pItem, char const* pDate = 0, char const* pCurrency = 0 );
Aside from a reference to an object into which it will return your item's value, each getValue member expects values for three required parameters -- an entity type, an entity code, and an item name. In addition, each accepts two optional parameters -- a string specifying the date as of which the item's value is desired and a string specifying the currency to use in processing and returning monetary values. Either or both of these optional arguments can be null (i.e., (char const*)0) to request the default value for that argument.
All getValue members return a non-zero value if they were able to submit your request to Vision and convert the value obtained to the return type associated with the overloaded member you invoked. They all return zero if they could not do both of these things.
Errors and Signals
int signal (char xSignal = 2);
This routine returns a non-zero value if the signal was sent; otherwise it returns zero. This routine has no effect on sessions accessed using the connect member function.
Because the submit, execute, include, and getValue member functions operate synchronously (i.e., they do not return until they have received a reply from Vision), you must create a separate thread to call this member function from your program.

#include "VDatum.h"
The VDatum class serves as the basis for returning arrays of data from Vision. In particular, VExtractWS objects return the data they retrieve from Vision in a VDatumArray (i.e., VArray<VDatum>).
enum VDatumKind { VDatumKind_NA, VDatumKind_Integer, VDatumKind_Real, VDatumKind_String }; Operations Category: Construction/Destruction
VDatum (char const* pValue); VDatum (double iValue); VDatum (int iValue); VDatum (); virtual ~VDatum ();
Access
VDatumKind kind () const; int isNA () const; int isInteger () const; int isReal () const; int isString () const; int asInteger (int &isValid) const; double asReal (int &isValid) const; char const* asString (int &isValid) const; operator char const* () const; operator double () const; operator int () const;
The asInteger, asReal and asString members return the VDatum's value if and only if it is of the requested type. These functions convert reals to integers and integers to reals if possible; however, they perform no other conversions. The asString member function returns a pointer to the actual string contained in the VDatum object. This pointer should be considered invalid as soon as the VDatum object that supplied it is changed or destroyed. These routines all set their isValid argument to a non-zero value if they were able to supply the VDatum's value in the requested form and to zero if they could not.
The char const*, double and int conversion members in this category are covers on the corresponding as... members that ignore the value returned in the isValid argument. They should be used only when you already know that the type of the VDatum object will allow them to succeed.

The assignment operators in this category set the type and value of the target VDatum object based on the value being assigned. If that value is a string, the target VDatum object makes a copy of that string.
The clear member function sets the VDatum to NA.
The parse member function sets the type and value of a VDatum object to the result of parsing an input string. The value you pass to the xExpectedKind argument tells this member function what kind of data to expect and accept. When VDatumKind_NA is passed as the value of xExpectedKind (the default), the parse member attempts to convert its string argument to a number. The conversion will fail if the string contains more than a syntactically valid number surrounded by optional leading and trailing whitespace. If the conversion succeeds, the target VDatum is set to that number. If the conversion fails and the string contains Vision standard NA representation, the target VDatum is set to NA. If neither a number nor a string is found, the target will be set to a copy of the string argument with leading whitespace removed. Passing other values from the VDatumKind enumeration to the xExpectedKind argument restricts the set of conversions considered. Passing either VDatumKind_Integer or VDatumKind_Real restricts this member to the requested numeric conversion. If that conversion fails, the target VDatum is set to NA. Finally, passing VDatumKind_String suppresses all numeric and NA conversions, setting the VDatum to a copy of this member's string argument with leading whitespace removed.

enum VExtractOrientation { VExtractOrientation_Unknown, VExtractOrientation_EI, VExtractOrientation_ET, VExtractOrientation_IE, VExtractOrientation_IT, VExtractOrientation_TE, VExtractOrientation_TI };
VExtractWS myExtractWS (&myConnection);Each VExtractWS object you create creates a corresponding Interface ExtractWS Vision object with which it interacts. To use a VExtractWS object, you use its set..., add..., and clear... operations to select the data you want. For example:
myExtractWS .setOrientationToEI () .setEntityTypeTo ("Security") .addEntity ("GM") .addEntity ("IBM") .addEntity ("HWP") .addEntity ("XON") .addItem ("name" , VDatumKind_String) .addItem ("price" , VDatumKind_Real) .addItem ("price@95", VDatumKind_Real) ;With the extract workspace parameters set, you use the run operation to request your data. The following example creates an empty two dimensional array which it fills with the data specified by the extract workspace:
VDatumArray myDataArray (2); if (!myExtractWS.run (myDataArray)) { reportError ("Run Failed\n"); exit (1); }The VDatumArray is resized and reshaped as needed to hold the result of your query. The following code illustrates how you can display the data you retrieved:
size_t rowCount = myDataArray.elementCount(0); size_t colCount = myDataArray.elementCount(1); for (unsigned int row = 0; row < rowCount; row++) { for (unsigned int col = 0; col < colCount; col++) { VDatum& iElement = myDataArray.element (row, col); switch (iElement.kind ()) { case VDatumKind_NA: printf ( "Row %u, Col %u Is NA\n", row, col ); break; case VDatumKind_Integer: printf ( "Row %u, Col %u Is The Integer %d\n", row, col, (int)iElement ); break; case VDatumKind_Real: printf ( "Row %u, Col %u Is The Real Number %g\n", row, col, (double)iElement ); break; case VDatumKind_String: printf ( "Row %u, Col %u Is The String <%s>\n", row, col, (char const*)iElement ); break; default: printf ( "Row %u, Col %u Has An Unrecognized Type\n", row, col ); break; } } }

The Interface ExtractWS class in Vision provides a single method to set an entity list. That method accepts a single argument that can be a list of entity names, a string containing a comma separated list of entity names, or a block specifying the Vision expression to run to generate a list of entities. The VExtractWS class implements these cases as four member functions -- addEntity, clearEntityList, setEntityListTo and setEntityListExpressionTo. addEntity and clearEntityList build the entity list as a list of strings. setEntityListTo defines the entity list as a single string containing a comma separated list of entity names. Finally, setEntityListExpressionTo accepts a string which it interprets as a Vision expression used to generate a list of entities.
The VExtractWS class also provides result value conversion types. When you specify an item -- either as the single item for time by entity and entity by time data arrays or as an item in an item list for all other array orientations -- you have the option of specifying the result data type of the item. If you do not specify a type, the Vision C++ interface kit will attempt to convert the data for that item into a number and to recognize Vision NA values. Data not recognized as either will be returned as a string. That is the effect of the default VDatumKind_NA value for the optional xKind argument to the setItemTo and addItem member functions. By specifying a different value for that argument, you can alter this behavior. In particular, by specifying VDatumKind_Integer, you are requesting that the item's data be returned as an integer or, if it cannot be converted to an integer, as an NA. Similarly, specifying VDatumKind_Real as an item's data type requests that its data be returned as a double or an NA. You can also turn off all conversion by specifying VDatumKind_String. In this case, the item's data is always returned as a string. By default, all row, column, and scalar label data is treated as string data.
Execution
int run ( VDatumArray& rDataArray, unsigned int fReset = VFalse );
By default, only the data access control parameters that have changed are sent to Vision. The fReset optional argument to this member function can be passed a non-zero value to cause all data access control settings to be re-sent as part of the execution request.

#include "VSockets.h"
int main (int argc, char* argv[]) { VSockets SocketSubsystem (VTrue); ... return 0; }You can use your favorite technique. Because your single VSockets instance must be passed to the constructor for VConnection objects:
VConnection myConnection (SocketSubsystem);and must be kept alive as long as any VConnection object is alive, you must have access to it whenever you create an instance of class VConnection and you must insure that your VSockets object is not destroyed as long as any VConnection object needs it. The VSockets constructor accepts a single argument which, when passed a non-zero value (VTrue will do in this regard), causes the constructor to make whatever initialization calls are required to make subsequent socket calls work in your application. This is an issue only in environments that use the 'winsock' implementation of sockets (e.g.., Microsoft Windows/NT, Microsoft Windows/95). If you have made those initialization calls yourself or are using other libraries that have already made those initialization calls, you may or may not need to pass VFalse to the VSockets constructor.
If you choose to do so, you may call the other member functions in this class to perform the operations they provide; however, most of these operations are intended for the use of the VConnection class.

The clear member function sets the content of a VStringBase object to the empty string.
The setTo member functions set the content of a VStringBase object to another string or to the standard string representation of a number.
The operator<< and append member functions append a string or the standard representation of a number as a string to a VStringBase object. The quote member function appends a quoted representation of a string to a VStringBase object.
The printf and vprintf member functions append a string formatted using printf style conventions to a VStringBase object.
The setBuffer member functions replace the internal buffer of a VStringBase object with a buffer you supply. That buffer must be allocated using either malloc or realloc. Once you pass its address to one of these member functions, you relinquish control over its lifetime and allocation to the VStringBase object. In particular, you must not free or reallocate it and should not retain a pointer to it. These member functions are provided primarily for the use of the VConnection submit member function which manages a potentially large buffer which it ultimately will return as the content of a VString object.

Contact - a solid 8 on the IMDB scale - is one of the few intelligently written and acted SF movies I've seen recently. SF movies tend to be either complete logical blowouts (Independence Day/Jurassic Park/Fifth Element) or farcical (Men in Black). While Contact has some problems with time (a multi-national project costing hundreds of billions of dollars completed in under three years based on schematics from out of this world?), it's mostly right on target.
What made this movie particularly good is the time Roboert Zemeckis took with his direction. Many SF movies are audio/visual assaults on the senses. There's an awful lot of quiet against a panorama of some of the finest special effects ever created. The first two minutes of the movie set the tone and style for what's to come. When there is a visual assault late in the movie, it's a brief interlude comparable to the climax of 2001.
The performances are pretty good - Rob Lowe is so smarmy as the Ralph Reedish-character you want to slap him - and Zemeckis wisely doesn't let the special effects overshadow the characters. People complained about the insertion of Bill Clinton video in this movie, but I thought it mostly worked. I would like to have seen a little more of John Hurt as the mysterious billionaire, but I suppose it added to his mystery.
I think Carl Sagan would have been proud of how his baby turned out.

How development drives eCommerce success
eCommerce businesses know that user experience and revenue go hand in hand. When users find shopping hard, slow, or confusing, they don’t convert and you don’t get paid.
That’s why your eCommerce site should be working hard for you – streamlining
your business and making shopping effortless. But without a well-developed site, you’re trying to build a great experience on shaky foundations.
BrainCode has developed more than our share of high-performing eCommerce sites. We focus on
delivering an experience users love, so you can get products off your shelves and into buyers’ carts.
Pillars of a great eCommerce experience
A seamless shopping experience. An eCommerce build must make shopping easy and secure. Pages must load quickly and reliably, with a consistent look and feel, compelling content, and search functionality that meets users’ needs and expectations.
The right integrations. A static site that’s disconnected from your business ecosystem creates data entry work for employees, and irritates customers with out-of-date information and limited features.
Interaction and personalization. Customers expect sites to “remember” them with features such as product recommendations, promos, and a tailored, content-rich experience. And as a customer-facing channel, the richest eCommerce experiences
offer ready access to real-time support such as live chat.

arecordmidi - record Standard MIDI Files
arecordmidi -p client:port[,...] [options] midifile
arecordmidi is a command-line utility that records a Standard MIDI File from one or more ALSA sequencer ports.
To stop recording, press Ctrl+C.
-h,--help Prints a list of options.
-V,--version Prints the current version.
-l,--list Prints a list of possible input ports.
-p,--port=client:port,... Sets the sequencer port(s) from which events are recorded.
A client can be specified by its number, its name, or a prefix of its name. A port is specified by its number; for port 0 of a client, the ":0" part of the port specification can be omitted.
-b,--bpm=beats Sets the musical tempo of the MIDI file, in beats per minute. The default value is 120 BPM.
-f,--fps=frames Sets the SMPTE resolution, in frames per second. Possible values are 24, 25, 29.97 (for 30 drop-frame), and 30.
-t,--ticks=ticks Sets the resolution of timestamps (ticks) in the MIDI file, in ticks per beat (when using musical tempo) or ticks per frame (when using SMPTE timing). The default value is 384 ticks/beat or 40 ticks/frame, respectively.
-s,--split-channels Specifies that the data for each MIDI channel should be written to a separate track in the MIDI file. This will result in a "format 1" file. Otherwise, when there is only one track, arecordmidi will generate a "format 0" file.
-m,--metronome=client:port Plays a metronome signal on the specified sequencer port.
Metronome sounds are played on channel 10, MIDI notes 33 & 34 (GM2/GS/XG metronome standard notes), with velocity 100 and duration 1.
-i,--timesig=numerator:denominator Sets the time signature for the MIDI file and metronome.
The time signature is specified as usual with two numbers, representing the numerator and denominator of the time signature as it would be notated. The denominator must be a power of two. Both numbers should be separated by a colon. The time signature is 4:4 by default.

For the first time in forever (or 6 years), a new 'Frozen' film hits theaters
Local theaters to host free themed release parties
by Christina LoreyMADISON, Wis. - Step aside, "Let it Go!" Parents will soon have a new earworm to get out of their heads.
After six long, "Frozen"-less years, the sound of children shrieking with excitement will once again fill local theaters, as the highly anticipated Disney sequel premieres Friday, Nov. 22.
The Disney sequel is expected to generate more than $100 million during its opening weekend.
As part of the winter hype train for the film, Marcus Theaters is hosting a free, "Frozen" family party from 12 p.m.-2 p.m. Saturday, Nov. 23 and Sunday, Nov. 24.
Marcus' family-focused celebrations will include snacks, make-your-own Olaf treat bags, and paper snowflakes.
Participating theaters include both the Marcus Point Cinema in Madison and the Marcus Palace Cinema in Sun Prairie. Marcus' locations in Appleton, Waukesha, and New Berlin are also participating.

Russia remains suspended as reinstatement process put on hold
Russia’s reinstatement process has been suspended by the World Athletics Council following fresh anti-doping charges against senior officials.
The Russian Athletics Federation (RusAF) has been banned from competition since 2015 and the suspension will now continue indefinitely as the Athletics Integrity Unit (AIU) made its latest recommendations to the council.
On Thursday “several senior federation officials” from RusAF were charged with and provisionally suspended for tampering and complicity.
In its findings, the AIU taskforce called for the immediate suspension of the reinstatement process until the latest charges had been answered.
World Athletics then confirmed on Friday evening that it had taken the step to halt Russia’s return to competition.
“There is an ongoing process and we have to respect that process,” taskforce chairman Rune Andersen said in the statement.
“There are charges laid by the AIU which we need to respect, and the AIU needs to receive feedback from RusAF by 12 December.
We will take this through to wherever we need to take it to protect the athletes and the sport
“When we have the answers from the AIU on what has been going on and what the process will be, then we will convene and look at the whole structure and we will come up with recommendations to the council.”
World Athletics president Lord Coe added: “It is really important that we continue with the process we began in November 2015. The recommendation that was given to us today, and unanimously accepted by the council, was in the spirit of that process.
“We will take this through to wherever we need to take it to protect the athletes and the sport.”
