Windows Messaging 'Register' and 'Capture'

[alukindo]

Hi:

NI Website has VIs for registering Standard WIndows Messages and capturing them via polling a Message Queue Loop. Messages such as Mouse Move, Mouse Down etc are converted to thier known integer equivalents. Then a windows message queue is pollled to read those messages when broadcast by another application.

In my case I need to regsiter 'Custom Messages' and listen or poll them in the same manner in LabVIEW. The challenge is how to derive the message unique integer values.

Does anyone have a warpper for this?

I am not a C++ programmer by any stretch and can only use LabVIEW.

Here is the link to the LabVIEW VIs for windows message registration an polling but only for standard windows messages.

OK:

I researched further and determined that the user32.dll has the function to assign Message Register integers for listening-to. I have attached a tip doc on how this can be done.

Perhaps this will benefit others looking on how to register custom window messages for listening via the Windows Message queue VIs.
