Protecting data types entered in text boxes.

I have a program where I ask for certain information that needs to be a #.

But I have some idiots who use it who seem to want to put periods or commas or other stupid things and it causes a run time error I know I can capture the run time error, but is there a way to make sure that what the person enters in a text box is simply a #?

and then I would want to prompt them to only enter a #.


Thanks.

Nick.

What about putting the following code in the Change() event (assuming the TextBox is called sleName):

Code:

---

If IsNumeric(sleName.Text) <> True Then
        MsgBox ("Error")
        sleName.Text = Left(sleName.Text, Len(sleName.Text) - 1)
        sleName.SelStart = Len(sleName.Text)
End If

the maskedit box control was built for such cases.
