Capture Close Button

[paas]

I am using Visual Studio 2005 to write a C# program. And I am wondering if anyone tell me if there is a programattic way to differentiate when a form is being closed via the Close() method as opposed to being closed via a user clicking on the control box 'x'? The CloseReason seems to be the same for either one, and I would like to know which 'Close' is occurring if possible. Thank You...

paas, I dont think there is a difference. However, when calling the form.Close(); method, you could set a flag and then in the OnClosing event, handle that flag and do whatever you want. Regards, Gareth.

Look up the OnClosing event handler, you can handle the close from there.

Thanks everyone for the replies. Unfortunately my initial message was not as detailed as it should have been. I know about the FormClosing event and how I could trap a flag I set before programtically executing a Form.Close(). However, what I really need to know is the difference between the closes that can be executed on the title bar. Either the 'x' close in the right corner, or the 'Close' that can be executed from the dropdown appears when you click in the left corner (on the icon). Can those be differentiated in the Closing event?

Not as far as I can tell. Even if overriding WndProc the same data is sent for both. m.Msg is WM_SYSCOMMAND (0x0112) m.WParam is SC_CLOSE (0xf060)
