Question:
How can I set up a TextBox object to allow only numeric values?
Solution:
To do so, you must write a script in the TextObject’s Change event. For example:
If Not IsNumeric(Value) Then
  Set WshShell = CreateObject(“WScript.Shell”)
  WshShell.SendKeys “{BACKSPACE}”
End If
  Set WshShell = CreateObject(“WScript.Shell”)
  WshShell.SendKeys “{BACKSPACE}”
End If
