    //if(hAppObj)
    TerminateExecutable (b);
   
    return VI_SUCCESS;

You are actually passing a wrong handle to TerminateExecutable: LaunchExecutableEx retrieves the handle of the executable in the last parameter (which by the way should be an integer passed by reference), while its return value is a status code. Now, you are passing this status code ('b' in your code) as the handle to TerminateExecutable, hence the error. Read the online help for the command.

Modify your code as follows:

int a=0;
int b=0;

int main()
{

    // ....

    b = LaunchExecutableEx ("C:\\DAS3000\\Das.exe", LE_SHOWNORMAL, &a);

    // ...

    
    TerminateExecutable (a);

    return VI_SUCCESS;
}

Why do you trash the handle which is given by LaunchExecutableEx() as Outputparamter ?

Your call to LaunchExecutableEx() should read

 status =LaunchExecutableEx ("C:\\DAS3000\\Das.exe",LE_SHOWNORMAL, &b);

if ( status < 0)  .... // some error handling

And don't forget to call

RetireExecutableHandle (b);

before the end of your program

But Roberto, I thought YOU are the on-line help.

But seriously Darnell: you might get some answers even quicker than Roberto answers them if you look at the help for functions you're having problems with.
