How to write a proper message hook?

[Arik Niceberg]

Hi !

I need to set a message hook to another application.
My HookProc is sitting in a Dll, and look like this:

int FAR PASCAL MsgFilterFunc (int nCode, WORD wParam, DWORD lParam )

Then I pass it to SetWindoshookEx:

hhookMsgFilterHook = SetWindowsHookEx (WH_MSGFILTER, MsgFilterFunc, hInstance, 0);

The compiling error that I get is:

SetWindowsHookEx : cannot convert parameter 2 from 'long' to 'long (__stdcall *)(int,unsigned int,long)'

Please, someone?!
