Regular expression with VBScript

[harish]

Hello,<BR>I am using a asp:RegularExpressionValidator control using ValidationExpression = " TheRegularExpression".<BR>My problem is I can't find a way to use the NOT matching Regular Expression. Normally, I can use the symbol ^ but it is not working within the ValidationExression field within the control. What can I use to not match the expression?<BR>i.e. not [ws!] <BR>and [^ws!] is not working!<BR>Thx<BR>ozone
