Regular expression

  Asked By: Juana    Date: Jan 08    Category: Asp.net    Views: 538

i'm trying to make a regular expression for an input-field of a winform.
I wanna force the user to enter strings, so not started with a number...
But my regex doesn't work...
Somebody sees what i'm doing wrong?

dim myRegEx As regex
myRegEx = New Regex("^(\d)*(\w)")

Dim match As Match = myRegEx.Match(gegevens)
If (match.Success) Then
End If

give this regex a shot:

myRegEx = New Regex("^[^\d*](\w)*")

you need to put the [^\d*] in there to tell it that you don't want digits to
start out with. it'll let digits pass through after the first nondigit

with a digit OR a *. If the string can start with ANYTHING but a digit
you can use:


If it MUST start with an alphabetic character, you can use:

I have been searching a lot for a regular  expression that validates a
user's input.
The input can be anything but not just numbers alone.

There can be numbers and any special characters in the input along with
other alphabets but I should not allow the user  to enter  just numbers or
special characters without any alphabets.

Can anyone help me with this??
