I am trying to use a DLL from a LabVIEW project that is meant to start the associated LabVIEW program. The executable runs fine, but when I call the DLL function from LabWindows/CVI the application does not run and the DLL function does not return. I believe I am loading the DLL and calling the function correctly because the LabVIEW project uses an INI file, and when I set it so the device number of the DAQ card I am using is incorrect LabVIEW generates an error. I'd like to be able to call a a LabVIEW DLL function to start up the LabVIEW application with user interface.
