Thanks, Gambit, I had no idea how to approach this issue.
I managed to create my first dll(!) (took me 4 hours) but how to pass a
MouseProc to SetWindowsHookEx?
//My mouseproc definition
LRESULT CALLBACK MouseProc(int nCode,WPARAM wParam,LPARAM lParam)
{
//my mouse stuff
}
//My dll hook-the-mouse function definition
void __export MyDllHookTheMouseFunction(void)
{
HHOOK MyHook =
SetWindowsHookEx(WH_MOUSE,MouseProc,MyInstance,MyThreadId);
}
I keep getting this compile error: Type mismatch in parameter 'lpfn'
Cannot convert 'long(__stdcall*)(int,unsigned int,long)' to
'int(__stdcall*)()'
More readable: Cannot convert A to B.
I understand that MouseProc is of kind A and SetWindowsHookEx 'lpfn' expects
type B.
So how to pass a type A (LRESULT CALLBACK) into type B (HOOKPROC)?
(I read Borland books and checked Internet, but could not find, I believe
I'm thinking the wrong direction)
greetings,
Henk
