Satish,
Using InputBox, you can't do anything until the user click OK and returns
the strings. Then you can test it.

If you make your own pseudo InputBox with a userform/textbox etc, you can
monitor the characters as typed in the KeyDown/KeyPress events and react
accordingly.

Hi All

Is there any easy way I can validate the string entered by the user in
an input box?

I basically don't want the user to enter characters that are considered
invalid for file/folder names. i.e., \ / : * ? " < |

Will I have to parse the string and check each character one by one or
is there any easy way to do it?

Ideas appreciated.

Thanks
Satish
