ALT+F4

[Ronni Marker]

Hello Gents. Am trying to alter the way ALT+F4 closes an application and hope I can get some guru help here. I have a component that calls an Windows form for a regstration page. On that Windows form I have two buttons. One closes the application by: System.Environment.Exit(); and the other button closes the application by: System.Enviroment.Exit(-1); The first only closes the form that runs inside the component, the later closes the whole application including what ever application who calls the component. Now my problem is that when the form that opens inside the compoent is active and a user hits ALT+F4, then the only the component closes and not the whole application. To me it seems that a standard ALT+F4 is like invoking System.Environment.Exit() and not System.Enviroment.Exit(-1). Is there any way I can force ALT+F4 to close the whole application like System.Enviroment.Exit(-1) does? Cheers, Ronni

Found the answer... private void form1_FormClosing (object sender, FormClosingEventArgs e) { if (e.CloseReason != CloseReason.ApplicationExitCall) { System.Environment.Exit (-1); } }
