[RESOLVED] VB.NET regex validation differs from Javascript

[savior14]

Given the following codes and my input is new@[email protected]
this one returns false

<asp:RegularExpressionValidator
     ID="REV1"
     runat="server"
     Display="Static"
     ErrorMessage="Error." 
     ControlToValidate="txtEmailAdd"
     ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" />

but this one returns true

Dim myMatch As Match = System.Text.RegularExpressions.Regex.Match(txtEmailAdd.Text, "\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*")
If Not myMatch.Success Then
    Result.Text = "Error."
    Exit Sub
End If

can anyone tell me what's wrong? Thanks in advance.
