ceWISE Optional Interface for C

This product is an optional add-on for the beWISE Professional and LAN versions. It works only in conjunction with either one of these products. It is implemented as a DLL. It allows C programs to access beWISE variables in a similar manner as VB programs, thus utilizing the power of beWISE variables in C.

Example “Translating”:

This example demonstrates how data can be exchanged between two programs written in different languages. The program CHRISTL is written in C (not C#); the program KARL is written VB.NET. Using beWISE variables the two programs can communicate without problems. In this example CHRISTL creates a variable with the name “EdelweissFound” and increments it every 100msec. KARL also creates this variable and installs an event handler for it. This allows KARL to be notified whenever the value of the variable changes. Every time CHRISTL increments the “EdelweissFound” variable, KARL’s MyCounter_Changed() event handler is executed and the value of the “EdelweissFound” variable is displayed.

Program CHRISTL:

#include <stdlib.h>
#include <stdio.h>
#include <time.h>

#include "ceWISE.h"
static int ew_handle; // handle of variable

main ()
{
long value;

    ceWISEinit(); // initialise the Edelwise environment
    ew_handle = ceWISEcreate( "EdelweissFound", ceWise_LONG );
    for ( value = 0; value < 10000; value++ )
    {
        ceWISEput(ew_handle, &value);
        _sleep(100);
    }
}

Program KARL:

Dim Create As New beWISE.Functions 'REQUIRED statement

Dim WithEvents MyCounter As beWISE.var_INTEGER 'number HANS counts

Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load

MyCounter = Create.New_var_INTEGER("EdelweissFound")

End Sub

Private Sub MyCounter_Changed() Handles MyCounter.Changed

EdelwiseLabel.Text = Format(MyCounter.Value, "#####0")

End Sub
