Answer 1

By default the text property of a textbox is a string. What you mean is that you wish to exclude all characters which are not numeric..

You can do this several ways in code.

1.) Use the validating & validated events to test the textbox string using the intrinsic function IsNumeric

2.) Test each key press as it is entered into a text box. and accept only numeric keys and cancel all other keypresses
