>I wish to be able to enter a e-mail number and a website address in a MaskEdBox.What is the mask that will allow me to do this? Thank You in Advance. (Ex.,(###)###-####)

You can't set mask for this. All you can do is to check if you have some important characters normally in the LostFocus or Validate event (like @ in the e-mail address and . in the website address).
