Hi Ali,

I am not an expert on this but needed it for some other reason just a few days back and got it resolved, mentioned below text can throw some light.
I hope it helps.


One way to trap key switching combinations is to write a keyboard hook. You install a keyboard hook by calling SetWindowsHookEx():

hKeyboardHook = SetWindowsHookEx(WH_KEYBOARD, KeyboardProc, hInstance, 0);

The KeyboardProc() function is a callback function that is called by the OS every time a key is pressed. Inside KeyboardProc(), you decide if you want to trap the key or let the OS (or the next application in the hook chain) process it:

  LRESULT KeyboardProc(...)
  {
     if (Key == VK_SOMEKEY)
    return 1;             // Trap key

    return CallNextHookEx(...); // Let the OS handle it
  }

To release the hook, you use:

  UnhookWindowsHookEx(hKeyboardHook);

There are two type of hooks: local and global (or system wide) hooks. Local hooks can only trap events for your application, while global hooks can trap events for all the running applications.

>I want to replace the procedures for copy (Ctrl-C) and cut (Ctrl-X) with my own routines. Is there any way that I can do that? I want to use my routines when the user presses those keys or clicks corresponding menu items on Edit of main menu. This only happens if the user opens a certain form. Otherwise, they (copy and cut) should do the normal procedure.
