CAPITAL LETTERS ONLY in Combo Box

For some reasons, you may need to let users key in ONLY CAPITAL LETTER in your text box or combo box. In the Key Down event, you can capture the key that user has entered and from there, convert the letter to capital letter and return to the text box. Instead of Key Down, you can also use Key Press event. The following codes will make it. Try it out yourself.

Private Sub TextBox1_KeyPress (KeyAscii As Integer)
Char = Chr(KeyAscii)
KeyAscii = Asc(UCase(Char))
End Sub
