why receive error C2365: 'Occur' : redefinition; previous definition was 'function' while trying to programm like the ni example windows_messaging_que.zip

Hello,

 

I try to detect WM like I saw it in a ni example (windows_messaging_que.zip). When I compile my code I always receive error C2365. I declare Occure as FARPROC like the examplecode too. In the extcode.h is Occur already defined as a function TH_PROTECTED MgErr _FUNCC Occur(Occurrence o); .

 

This part is from the example:

FARPROC Occur; //A function pointer to the Occur function inside LabVIEW.exe

 

Has anyone an idea to fix that problem?

 

Best regards, AndreasE

I made a new test. I tried to build solution with the original code I found here: http://zone.ni.com/devzone/cda/epd/p/id/4394 Same error will be issued.

Hello Andreas,

attached you’ll find the modified “Windows Messages for LabVIEW MT.cpp” file.
I was able to compile the file, after I modified it.
You can use your “Diff tool” in your IDE  to see the differences.

Kind regards
