How to catch Control-V in C# app?

Question

I've tried to override WndProc, but no message show up on paste event.

Then I tried to create custom filter and using method PreFilterMessage I was able to catch message with value 257 (KEYUP event), but that's not enough...

Use:

 protected override void OnKeyDown(KeyEventArgs e)
 {
      if (e.KeyCode == Keys.V && e.Modifiers == Keys.Control)
      {
            MessageBox.Show("Hello world");
      }
      base.OnKeyDown(e);
  }

Make sure your form KeyPreview = true.

FYI - Thats not me asking the question – Goran Oct 06 '08 at 08:55
First you'd need to implement such feature (using context menu strip i guess). You'd have full control over it anyway – Goran Oct 06 '08 at 18:13

You can do this by:

Intercepting the Ctrl+V in KeyDown (or KeyUp) of your form
Creating a menu in your form that contains a Paste option that has the Ctrl+V shortcut (this would maybe be better since you will have users looking for the options)
Intercepting the KEYDOWN message like you described in the question and checking whether Ctrl is pressed at that time (I think this is the hardest of all 3).

Personally I would go for using a menu option.
