Hi, Naoto:

>Which KeyPress() event? The Form or TextBox? If the one in the Form object, did you set KeyPreview to .T. ?

1) Textbox.KeyPress()

2) Yes. KeyPreview is set to .T.

Anyway you must understand before posting this I put code after IF !A... and. after IF !B and the code worked. So CHRSAW() returns .F. despite there are keystrokes remaining in the buffer.
