Global hook giving memory error

[-h-]

Hi.

I have a following problem.

I have installed a mouse hook for a application opened by my app. Lets say,
for WinAmp. When WinAmp receives any mouse events, a memory error occurs
(The instruction at "0x..." referenced memory at "0x....". The memory could
not be "written").

I have my hooks set in a dll file like "SetWindowsHookEx(WH_MOUSE,MouseProc,
hInstance,processThreadId);". The hInstance is received GetWindowInstance
and processThreadId by GetWindowThreadProcessId. The WinAmp window handle is
used for both.

I think this problem is in my dll file. It seems like the dll is trying to
write something to a place where it is not allowed. The hooking works for my
application window, but the hooking the opened applications will crash.

Any ideas? Thanks.

The hInstance should be the hInstance of the DLL. Don't set the hook from your application, but from a procedure in your DLL and use the hInstance of the DLL, that is how to inject DLL into foreign process.
