[RESOLVED] [2005] Word and number filter

hello,
I am trying to filter 2 things:
1) a username, if the username contains two numbers at the begining of the username then do something

2) look at a string of text if the text contains certain words then do something

I have had a search around and have found filters but they replace the words, if anyone can offer any help that would be great


many thanks

To validate username:

VB Code:

Private Function ValidUserName(ByVal UserName As String) As Boolean
        Dim reg As New System.Text.RegularExpressions.Regex("\d{2}\w+")
        Dim M As System.Text.RegularExpressions.Match = reg.Match(UserName)
        Return M.Success
    End Function

To look for a specific string

VB Code:

If text.IndexOf("SearchString") <> -1 Then

thanks ComputerJy

for the username part, if I wanted to add a msgbox saying username valid if where would I place it.

thanks

VB Code:

Private Sub UserNameEntered(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If ValidUserName(UserNameTextBox.Text) Then
            MessageBox.Show("Valid Username")
        End If
    End Sub

thanks very much
