Use Mouse Down Event, Then Clear the Clipboard ..

private void TxtBox1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
    Clipboard.SetDataObject("");
}

Try It ..

The first thing to do is to set the ContextMenu propert of the textbox equal to a new empty 'ContextMenu', then you can either disable the paste keys in the whole form, or on the individual control.

protected override bool ProcessCmdKey(ref Message msg,Keys keyData)
{
      if (keyData==(Keys.Control|Keys.V) || keyData==(Keys.Shift|Keys.Insert))
            return true;
      else
            return base.ProcessCmdKey(ref msg,keyData);
}

If you choose to do it for the whole form, then it's just a matter of adding the above code to the form class. If you want to it to just apply to a sinlge control, you have to create a new control which inherits from TextBox, and include the above code in the overridden class.

Hope this helps
