In the keypress event of the textbox, have something like:

Code:

Private Sub Text1_KeyPress(KeyAscii As Integer)
If Chr(KeyAscii) <> "a" And Chr(KeyAscii) <> "b" And KeyAscii <> 8 Then KeyAscii = 0
End Sub

The KeyAscii <> 8 is to enable backspace.

filter the results by their keycode value in the keydown event. if they do not fit your criteria set keycode to 0

KeyCode won't work. It needs to be KeyAscii in the KeyPress event.
