Enter code into KeyPress Event
Expand|Select|Wrap|Line Numbers
  1. Private Sub TextBox1_KeyPress(KeyAscii As Integer)
  2. If (KeyAscii < Asc("0") Or KeyAscii>Asc("9")) And Not KeyAscii=8 Then
  3.   KeyAscii = 0
  4.   Msgbox "Invalid Number"
  5. End If
  6. End Sub
  7.  
You need KeyAscii = 8 to enable BackSpace key

re: Control format of input

What type of control are you using to enter the information? If it's a text box, you might instead try looking into the Masked Edit Control - it allows you to control the format of the input.

Oh, and by the way. Please try to use a title which reflects what is in your message, not just "help".
