>It seems the compiler doesn't understand the Dll Function calls. I defined them all in the init of a custom class. I tried to add the dll to the project under API Librarys but I now get an error stating "Library File _isource.dll is invalid."


You can specify that the functions are EXTERNAL. This will get the compiler to quit complaining.
