I'm trying to use SDK calls to drive a joystick in a CVI application.
Typical SDK-directX calls are, for example, the following:
CreateDevice(...)
EnumDevices(...)
SetDataFormat(...)
etc.
I get two main errors when the program is launched:
1) "pdi->lpVtbl->EnumDevices( ...... " call provokes a "dereference of null
pointer" during execution
2) Undefined symbol '_c_dfDIJoystick' , during link phase
All the necessary .h and .lib files are used as suggested in SDK
documentation.
There is someone who can help?
Thank you so much in advance for suggestions.
Sergio
