Hy everybody,
I'm trying to use a video for windows callback funktion wich is called capSetCallbackOnFrame in a MFC program.
Trying to use this macro is easy: capSetCallbackOnFrame ( hWnd, mycallback ).
But it's much more difficult for me to create the function mycallback!!
I tried to create a member function of the view class, because vfw becomes initiated in this class, LPRESULT PASCAL mycallback ( ... but it didn't work.
I'm a beginner and all I did was blind trying, so can everybody tell me, how it works and explain me why it works this way ??
Hope you'r able to help me, I'm becoming mad of this !!
Help,
SAM
