My Form code:

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    FARPROC   HookProc;
    HINSTANCE DLL;
    HHOOK   Hook;
    DLL      = LoadLibrary("DLL.dll");
    HookProc = GetProcAddress(DLL, "KeyboardHookProc");
    Hook     = SetWindowsHookEx(WH_KEYBOARD, (HOOKPROC)HookProc, DLL, NULL);
}
//---------------------------------------------------------------

MY Dll code:

#include <windows.h>

LRESULT CALLBACK KeyboardHookProc(int code, WPARAM wParam, LPARAM lParam)
{
 return CallNextHookEx(NULL, code, wParam, lParam);
 }
//---------------------------------------------------------------


Is this SetWindowsHookEx() ok, should I simply remove return 0 instead of
CallNextHookEx(NULL, code, wParam, lParam) from dll?

Thanks in advance,
Tom.
