VB hWnD

[leonlobo]

I trying to interface LabVIEW to some hardware using the activeX controls
that came with it. Problem is that these controls were probably designed to
be used with VB or VC++. One of the parameters that have to be passed to the
control is a window handle for images. With regard to LabVIEW, what is this
and where do I wire it from?????

Lobo;

You need to get the LabVIEW window reference number. For that, you need to make a call to Windows API. NI provide the necessary vi's in the Knowledge Base:

How Do I Get the Instance (Windows handle) of a LabVIEW Window?

Windows API Function Utilities (32-bit) for LabVIEW

Let us know if you need more help.

Thanks Enrique. Managed to get that working. I now ant to be able to get the
handle of a picture control or intensity graph to display an image. Any
ideas.
