Dear All,
How Can I restrict the paste option in Richtextbox.(Ctrl+Shift+Keydown).If I suppress this using the keydown event,If some one from other program captures the handle of the window.And after capturing the handle ,By using sendkeys I am able to insert the text in that.I want to restrict the input from sendkeys.But I want the user to enter the text, not to copy from other outside application.How can i do this

Thanks In Advance
Dana
