I have a cbo in which are entered surname,prename;Date of birth. It is
important that the comma be a comma, and that the semicolon be a semicolon.
Is there any way that I can analyze the characters entered (as they are typed)
, to insure that they are not, mistakingly, a period (instead of a comma) or
a colon
(instead of a semicolon). Any help would be appreciated.
TIA, Richard

This is a mutant, but it's a test/example. If you trap the key pressed
in the KeyPress event of your control, you can reject/discard the
characters you don't want in your control. The following code rejects
the semi-colon, period, and colon.


Private Sub Text0_KeyPress(KeyAscii As Integer)
'---Use this if you want to the code to respond differently to
different keys
' Select Case KeyAscii
' Case 46 'period
' KeyAscii = 0
' Case 58 'colon, I think...
' KeyAscii = 0
' Case 59 'semi-colon
' KeyAscii = 0
' Case Else 'do nothing
' End Select

'---or this one if you just want to throw away/ignore a fixed set of
keys.
Select Case KeyAscii
Case 58, 46, 59 '---list of the asc(":") values that you want
to reject
KeyAscii = 0
Case Else 'do nothing
End Select
End Sub

yes, it's a screwy example. You'd use one or the other....

Piet;Thanks for reply, which seems to be just what I seek. Only problem I
have is: how do I call this sub?
I'm entering "Text0KeyPress in my keypress event for my cbo, but I'm getting
errmsg "sub or function not defined. (with or without the parenteses). What
am I missing?
TIA, Richard

Probably the most foolproof way of doing it is to copy this part into
the KeyPress event of your control (the textbox).

Select Case KeyAscii
Case 58, 46, 59 '---list of the asc(":") values that you want to
reject
KeyAscii = 0
Case Else 'do nothing
End Select

to get the KeyPress event of your control... right-click on the control
in design view, select the KeyPress event, and then when you get the
code window, paste in the above code..

yup! worked perfectly! Your first msg seemed to imply that I needed it as a
separate function.
Thanks again, Richard
