MaskedTextBox: mask for a uri?

Oct 9, 2008 at 9:57 AM
Using this library's MaskedTextBox, is it possible to create a mask for a URI (that would accept all types of URIs)?  Acceptable input would basically just be a string of alphabetic characters, of arbitrary length, followed by a colon, followed by some more characters.  If it's possible, then what does the Mask string look like?
