Obtaining HHOOK for CallNextHookEx

In my KeyboardProc in my dll, how can I obtain the handle returned to the hook by SetWindowsHookEx so that I can call CallNextHookEx?

It's passed to your hook function. Read the MSDN.

huh

Oops. My bad. Hook handle is return by SetWindowsHookEx.

Eg.

Code:

---

LRESULT __stdcall LowLevelKeyboardProc (DWORD code, WPARAM wparam, LPARAM lparam)
{
  if (code == HC_ACTION) /* A key was pressed */
  {
      KBDLLHOOKSTRUCT *hookstruct = (KBDLLHOOKSTRUCT *)lparam;
      /* Send key to our main program */
      PostMessage (hWnd, WM_U_HOOKMSG, (hookstruct->vkCode << 16) + hookstruct->scanCode, hookstruct->flags);
  }
  /* Otherwise pass it down... */
  return (CallNextHookEx (hookHandle, code, wparam, lparam));
}

where the init call is:

Code:

---

hookHandle = SetWindowsHookEx (WH_KEYBOARD_LL, (HOOKPROC)&LowLevelKeyboardProc, HInstance, 0);

Yeah, my problem was that the proc function was assigned in a dll, separate from the actual hook call. I just ended up using a startup function.
