Do anyone know how to evaluate each character a user
enters to determine if it is numeric? I don't want to
let the user type in an alpha character. If they hit a
alpha character I want the computer to beep but retain
the numbers they already typed in.

Your help is appreciated
 
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As
System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar.IsNumber(e.KeyChar) Then

MsgBox("Numeric")

End If

End Sub

What if it's not numeric? How do I not add that
character to the textbox. In VB6, I just set the key
code to 0.
 
Else
e.Handled=True

End If

I'm afraid this does not work. The alpha character is
still added to the textbox. Any other suggestions?
 
It does work. Look at this NOTE ( KEY PRESS EVENT ). I Just tested it

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As
System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress

If Char.IsNumber(e.KeyChar) Then

'Do nothing

Else

e.Handled = True

End If

End Sub
