How do I generate an occurence in a DLL that LabVIEW can trigger on?

[Mattias_Ericsson]

I have some C++ code that has some interupt handling and I want to put this in a DLL. But I want to build my test system in LabVIEW and would therefore like to get an occurence trigged by the DLL so my LabVIEW application do not have to "poll" the DLL. Basicly I would like this to work as the DAQ occurence work.

I know that this is possible but I do not know how to implement this in C++.

Thanks,

Search the zone for Windows Message Queue Library. This can be used to intercept custom application messages and works in much the same way as DAQ Events.
