>I'm trying to cancel a character string produced by a keypress of a programmable keyboard from being sent to a textbox by validating the first character in the string. Thus far the only methods I've achieved are (1) to let the string write to the textbox and then validate the leftmost character and input an empty string or (2) to disable the textbox by validating the first character in the keypress method of the form. The ideal would be to clear the keyboard buffer from the keypress method, but that doesn't seem to work.

Edward:
We had a similar problem of canceling mouse clicks and other key presses performed by users while processes where running. One way of canceling the keypresses were to give the following commands in the guilty method.

The principle of this is to wait until all keystrokes are processed via the inkey trap.

DO WHILE INKEY("M") > 0
ENDDO

Hope this helps.
