WM_SET_OCCURRENCE - How do I get it (without a CIN)?

[Niels]

I am attempting to have labview receive messages that are sent by DLL drivers for a 3rd party hardware device(Immersion MicroScribe DLX). These messages are sent via the "SendMessageTimeout" command. The Windows Message Queue example on the NI site is not able to "hook" these messages (it seems that since they are not "posted" they won't be hooked?). I have decided that I might write a "proxy" to receive the messages and then set an occurrence in labview. Unfortunately, I am using Metrowerks Codewarrior compiler - which doesn't support CINs for labview, so I am not able to call the function "GetLVAppWindHandle". Does anyone know of any other way to get the message ID, WM_SET_OCCURRENCE?

I would check out the following developer exchange post: http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RNAME=ViewQuestion&HOID=506500000008000000DD170000&ECategory=LabVIEW.LabVIEW+General

There is an example on this post that illustrates getting a handle to a LabVIEW window.

Or, you may just want to try and get your hands on a copy of MS Visual C++.

Thanks Matt. I'll check that out. I think that I also discovered another way, however. All I need to do is create a DLL, and then have labview pass the handle on to the program when it initiates it from the command line.
