New Post: CreateThreadObject In Built Executable

I wondered if somebody could help with an issue that I'm having with CreateThreadObject. When I work with the example from the documentation everything works well in the development IDE in Foxpro (VFP9 SP1), but when I call the DLL function from a built executable, i get an error with Unknown Member Callinfo. If I take out the reference to callinfo out on the dll side, I then find that its a blocking call, and not an async one. As I said, there is no error if I try the example in VFP command window, and everything works as expected. I was wondering if it might be an environment issue somehow...
