Is it possible to intercept/redefine Ctrl-Ins and Shift-Ins in a TextBox Control ?
for example when I press Ctrl-C or Ctrl-V the KeyPress event is fired and is also possible tointercept Ctrl-C Ctrl-Vviaa Menu Strip

Thank you
Manuel

Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form. I had to guess at the meaning of the shortcut keys, much like your user will.

using System;
using System.Windows.Forms;

class MyTextBox : TextBox {
protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
if (keyData == (Keys.Control | Keys.Insert)) {
this.Paste();
return true;
}
if (keyData == (Keys.Shift | Keys.Insert)) {
this.Copy();
return true;
}
return base.ProcessCmdKey(ref msg, keyData);
}
}

Well... It seems thatcan intercept Ctrl-Ins or Shift-Ins only using a MenuStrip or ContextMenuStrip...

Hi Manuel Marini,

Could you please tell me why you want to make these two shortcut keys? Shift + Insert key has been defined by the system. If you replace it with your own logical, will it affect user experience?

Anyway, I think nobugz’s sample code is suitable for your requirement. Override ProcessCmdKey can intercept user input in your .NET application. Since system doesn’t define “Control+Insert� you can easily handle other event such as the KeyDown event tointercept "Control+Insert" and codeyour own logical.

If I misunderstood you, please feel free to tell me.

Sincerely,

Kira Qian

Hi,

The content of the text box has to be sent to a very old communication system (telex) this system doesn't support some characters. I need to filter these characters directly when the user types themand I need also to filter the paste operation (Shift-Ins and Ctrl-V) to have WYSIWYG editing.
For example è has to become E', $ has to become USD.

I was looking for a solution with some kind of subclassing and overriding the ProcessCmdKey is perfect for my needs.

Thank you very much Kira Qian and Hans Passant.
