SetWindowsHookEx in Win 9x/ME/NT4

Hello...

I'm trying use SetWindowsHookEx() in windows 9x/ME/NT4.

Somebody know?

Obrigado...

Use it for what?

I use with KeyboardProc (WH_KEYBOARD) and MessageProc (WH_MSGFILTER).

...

And your question is that you don't know how to do what you want to do with the function?

I want make this...

What are you having problems with? You need to narrow your question down.

I'm making thus:

Code:

---

/* Global Variables */

HHOOK hMsgFilter;
HWND ToolBar;

/* ... */

LRESULT CALLBACK MessageProc(int Code, WPARAM wParam, LPARAM lParam)
{
  RECT rc;
  MSG *msg;
  long x, y;
 
  if(Code < 0)
  {
      return CallNextHookEx(hMsgFilter, Code, wParam, lParam);
  }
 
  msg = (MSG*)lParam;
 
  if(Code == MSGF_MENU)
  {
      GetWindowRect(ToolBar,&rc);
     
      if(msg->message == WM_MOUSEMOVE)
      {
        x = LOWORD(msg->lParam); y = HIWORD(msg->lParam);
        x -= rc.left; y -= rc.top;
           
        SendMessage(ToolBar,WM_MOUSEMOVE,msg->wParam,MAKELPARAM(x,y));
      }
  }
 
  return CallNextHookEx(hMsgFilter,Code,wParam,lParam);
}

/* ... */

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
  hMsgFilter = SetWindowsHookEx(WH_MSGFILTER,(HOOKPROC)MessageProc,GetModuleHandle(NULL),0);
 
  switch (msg)
  {
      case WM_DESTROY:
      {
        UnhookWindowsHookEx(hMsgFilter);
        PostQuitMessage(0);
      }break;
     
      default:
        return DefWindowProc(hwnd, msg, wParam, lParam);
  }

  return 0;
}

In this way not function for windows 9x/ME/NT4.

Obrigado...

I just want know, why this fails in Win9x/ME/NT4...
