How do I stop the Textbox Shortcut Keys (e.g. Ctrl V) from working. I have tried to capture the KeyDown KeyPress and KeyUp events but I can still paste the clipboard into the Textbox.

U have to catch the WM_PASTE message windows fires when u use U can do this by overriding the next method protected override void WndProc(ref Message msg) { switch(msg.MSG) { case WM_PASTE : do nothing break; case WM_CONTEXTMENU : do nothing break; //to disable the right clicking contect menu. } } in the class define the variables WM_PASTE and WM_CONTEXT als following : private const int WM_PASTE = 0x0302; private const int WM_CONTEXTMENU = 0x7b; goodluck

My application allows the user to construct an SQL search using set fields I have written a number only textbox but the user can still paste characters into this field. Without alot of extra error checking the best way is to disable the paste function.
