Urgent Help with field Input

peto813 · #1 (**permalink**) 08-31-04, 20:37

I am creating an application using Visual Basic 2005 (similar to .net)that reads values from a set of fields in order to perform numerical calculations. My question is the following, how can I prevent users or at least display a messagebox whenever users enter characters other than numerical characters?
Thank you in advance

Put the following code in the KeyPress event of your textbox:

Code:

'The User Pressed Enter
If KeyAscii = 13 Then
    'Do your processing code here

'The user pressed non numeric character. Cancel the entry.
ElseIf KeyAscii <> 8 And (KeyAscii < 48 Or KeyAscii > 57) Then
    KeyAscii = 0

End If
