That threads got about a million different ways fo doing it.

Basically, in the KeyPress event, decide if it's a character you want or not, and if it's not, set KeyAscii = 0

eg:

    Select Case KeyAscii
        Case 48 To 57 'Numbers
        Case 46 ' . (period)
        Case 8 ' Backspace
        Case 10 'Linefeed
        Case 13 'Carriage return
        Case Else
            KeyAscii = 0
    End Select

Other interesting ascii values you might want to look for are Ascii 3, 22 and 26. These equate to Ctrl-C, Ctrl-V and Ctrl-X.

Assuming you handle the Ctrl characters, the only other way to put text into the text box is right clicking and pasting, in which case you need to check the TextBox_Change event and remove any non numeric characters.

Remember to keep the cursor at the current location (nothing annoys users more than a seemingly random moving cursor)

And 10 points to anyone who can tell me why the ctrl characters come through as those three ascii values (which officially aren't used by Windows). It's a particularly ingenious reason.

Basicly, it's a good thing to let all the ASCII values < 33 trough, because that are the 'system' characters (space, tab(?), enter, ctrl... etc)
