Hi

Instead of closing the form when the close button [X] is clicked, I want the
form to minimise. Does anyone know how to do this (using C#)?

Thanks for any help

John

Hi John,

You can hook the "closing" event of the form and minimaze it (and cancel the
event)

private void Form1_Closing(object sender,
System.ComponentModel.CancelEventArgs e)

{

this.WindowState = FormWindowState.Minimized;

e.Cancel=true;

}

Thanks for your suggestion Fran?ois, but thats not quite what I was hoping
for. When my application is running and I choose to shut-down my computer,
my application just gets minimised and stays running and my computer does
not shutdown (because the Closing event is cancelled). What I think I need
to know is how can I tell if the user has clicked on the [X] button so I can
handle that instead of hooking in to the Closing event?

Thanks again

John

Hi John,
Maybe you can try overriding the WndProc and handling the WM_SYSCOMMAND
message, then change the SC_CLOSE command to SC_MINIMIZE before passing it
to base.WndProc method. For more information , you may read the
documentation of the WM_SYSCOMMAND message.

Does it resolve your problem?
Please feel free to reply this thread if you still have problem on it.

Have a nice day.
