validating using regular expressions

[dec21st]

just like how it can be done in asp.net, can i use regular expression to validate a vb.net application?

wat are the common or usual way to validate textbox?

 

[kulrom]

PrivateSub TextBox1_Validating(ByVal sender AsObject, _

ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating

'code goes here

EndSub


or


Private Sub TextBox2_Validated(ByVal sender As Object, _

ByVal e As System.EventArgs) Handles TextBox2.Validated

'code goes here

End Sub



Cheers
