Child form, which stays in front

[Ronen Kfir]

I'm looking for a way to make an authentication form to my windows form based app. I want this form to be left in front of the parent main form, until user succeccfuly authenticate. If he press cancel it close the parent form. No other from may be load in front if this authentication form. TIA, Ronen Ronen

You may use the ShowDialog() method to wait for a response and cast its return with DialogResult class. Or in the Deactivate event of this login form write: Activate().
