In good old MFC, the DDX routines would have built in validation for form entries. For example it was possible to automatically check if the user entered a string in a text box meant for numeric input. Is there any such mechanism in Winforms?

It looks like it hasn't been updated since 2007 - which is probably fine - I'm just being extra cautious before adopting something new into my app that i haven't used before. Is there any reason not to - or what does it do for me t...
This question asking for a phone number format API in Java got me wondering why such an API doesn't seem to exist. Given the number of validation classes available under Apache Commons, I would have thought such an API would be included. My question is, does anyone know of a phone number formatting/validation library available in any l...

I found some sample code like this : protected override void OnError(EventArgs e) { ...
