hi
you can use the _keydown method -
Private Sub AnObject_KeyDown(KeyCode As Integer, Shift As Integer)
-
If KeyCode = vbKeyBack Then
-
.. enter your code here ...
-
End If
-
End Sub
-
or the _keypress method -
Private Sub AnObject_KeyPress(KeyAscii As Integer)
-
If KeyAscii = 8 Then
-
.. enter your code here ...
-
End If
-
End Sub
-

Thank you very much for your answers.

Hi,
I have web form with 2 submit buttons. One has the PostBackUrl property set
to another page, and the other has nothing and falls through to the default
behaviour of posting back to it's page.
If I press the the cross post button I move to the 2nd page as expected. If
I then use the browser's backspace button to take me back to the page with
the buttons, then press the other button, the submit action still takes me
to my 2nd page.

viewing and debugging into.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
