Regular Expression

[Mac McMicmac]

I'm implementing a RegularExpressionValidator and need assistance with the
value to put into the ValidationExpression property. The control needs to
validate a textbox that must contain a complete file path. I know these
things can get pretty complex - so I'd be happy to keep it simple by having
the expression simply verify the text entered into the textbox ends with
..doc, .wav, or .pdf. If it's not too much to ask, I'd like for the
expression to ensure that there is at least one \ and at least one character
preceding any of the three extensions listed (.doc, .wav. .pdf).

Thanks.

Mac,

Start with this regex and modify the end part for each of the file
extensions you need (.txt, .doc, .wav, etc.).
