sorry probably very simple

Question

i think i am being a muppet at the moment.
i have a OKbtn that is designated as the accept button for the form. how can i stop the window from closing if the ok fails. for example on a login screen if the username or password is not correct i want the form to stay there
cheers

it was simple. had set the property of the button to dialogresult. this meant that it forced the form to close. soon as i removed this it worked as planned

Your form has a closing event (you may find this in Form VAse Events).
This event has an argument of type CancelEventArgs. Simply set this argument to true and your form will not close.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub
Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
e.Cancel = True
End Sub
