Command Line Arguments in Labview

[David]

Does anyone know if it is possible to invoke a program developed with
Labiew with command line arguments and then use those arguments within
the program?

If so, how can I do this?

Thanks ... Dave

Dave,

It is possible, but very tricky... When in an application it is relatively
easy to get the command line arguments using GetCommandLine (Kernel32 win32
API).

When running VI's the messages are send to LabVIEW.exe and are harder to
get.

Regards,

Wiebe.

Dave,

More about the tricky part... Windows returns an array of strings. The
elements are seperated with zero's (\00). LabVIEW sees this as the end of
the string. So the result is an empty string.

The trick is to get the pointer of the string, and the string at the
pointer. Concatenate the string with an extra space, and add the string
length to the pointer. Repeat until the string length is zero.

BTW. use GetCommandLineA, not GetCommandLineW.

I'll send you the VI I've made. If anyone else want it, send me a mail.
Please use >GetCommandLine< as subject.

Regards,

Wiebe.
