VB.net Prevent Windows form from being closed manually by user

Hi

In VB.net. I use code to close my Windows forms once the user has made a selection. What is the best way to prevent the user from closing any form manually by clicking on the cross on the top right of the form. I want to disable the manual closing of all my forms.

Thanks

Simply control the Form_FormClosing event in this way:

Private Sub Form1_FormClosing(sender As Object, e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
    If e.CloseReason = CloseReason.UserClosing Then e.Cancel = True
End Sub

Hope that helps.
