Allow only upper case letters in text box

How can I only allow user to enter upper case letters
into a text box, and if he enters a lower case letter,
change it to upper case.

in vb6 I would use the keypress event and change the key
to upper case, but in .net the key is read only.

Set the textbox's 'CharacterCasing' property to 'Upper'.
