How can I temporarily prevent a form from getting focus/activating?

Question

my application opens n forms and the user can freely switch back and forth among these forms. When the user decides to confirm the operations performed on one of the forms, I would like to block the other ones until this process (which can potentially open MessageBoxes and/or other forms) comes to an end. It is not enough to disable the forms, since the user can't do anything on them, but the Activated event is fired, and this is exactly what I want to avoid. I tried to set ControlStyles.Selectable to false to all these forms, but it doesn't work.

Just in order to make it clearer, the forms cover the whole screen, so the users activate them clicking on the taskbar. This is the situation where opening a modal form and having the confirm code executed there does not prevent the Activated event to be fired.

Answer 1

尝试使用Form.ShowDialog（）方法。

Answer 2

You can use Form.ShowDialog Method method to display a modal dialog box in your application. When this method is called, the code following it is not executed until after the dialog box is closed.
