Some time ago, I was doing myself a windows hook with Object Pascal (Delphi) and it worked correctly, but now, I've been working on a hook that doesn't work at all. In the hook procedure, in the dynamic library
i put this little code in the header file :

extern "C" {
HOOKDLL_API LRESULT CALLBACK WndHKK(int code, WPARAM _key, LPARAM _other);
}

and in the source file i put this one :

__declspec(dllexport) LRESULT CALLBACK hookproc(int code, WPARAM _key, LPARAM _other)
{
return CallNextHookEx(_h, code, _key, _other);
}

Then, for the test program I wrote the following code :

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
MSG m;
HHOOK hook;
HMODULE lib = LoadLibrary("HookDLL.dll");
HOOKPROC proc = (HOOKPROC)GetProcAddress(lib, "LInit"); // It returned the

if (!(hook = SetWindowsHookEx(WH_KEYBOARD, proc, lib, 0)))
{
HOOKERROR;
return 0;
}
SendMessage((HWND)hInstance, WM_KEYDOWN, 98, 0);
while (GetMessage(&m, 0, 0, 0))
{
TranslateMessage(&m);
DispatchMessage(&m);
}
UnhookWindowsHookEx(hook);
return 0;
}

And the GetProcAddress didn't gave me the value I had expected ...
Later I tried loading the library implicitly with the process, and it work
correctly creating the HOOK but when I test it debbuging from the DLL I realised
that it didn't passing through the code in the DLL. Please , help me quickly

hello
i dont do windows programming in C++ but in asm so i couldnt get much from you code.
did you share the data section of dll and your program which are must for system wide hooks. just a thought.
