You use the WithEvents keyword when your declaring an instance of a class that generates events that you're going to handle.

javascript has regex, so does .NET. Just use a regular expression.

This should do it
Function IsValidEmail(strIn As String) As Boolean
' Return true if strIn is in valid e-mail format.
Return Regex.IsMatch(strIn, "^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$")
End Function
God bless msdn...

If you're using .NET, then, yes. Just go into the Tools/Options/Text Editor, choose VB, and check the box.

You know, you ask a different question every time. Yes, of course you can work out a line number from a textbox. Just count the number of newlines.

Hi,
you can take a look here for a start:
http://www.codeproject.com/cs/samples/linenumberingapp.asp[^]
There are also heaps of hits on google which let you use GetCurPos() and GetCursorPos() to get the position of the caret if you wish to return the line you are currently editing. I'm sure there are some built in things in the framework, though I'm really tired and can't think at the moment.
Cheers,
Daniel
