i'm not sure why this is, maybe some of you guys can help me out.
i have an MDI application.
i have a MDI child inside the parent.
i click the "X" of the MDI window to shut down the application.
i have a call to MessageBox.Show in the Dispose(bool) method of the child.
nothing shows.
i put a break point, and i can actually step through it and it hits the line where i show a message box, but it passes through it and nothing comes up.
i need this functionality because when the application closes i need to ask a question for each MDI child. it works fine if i close the child inside the MDI parent.
is there some event i can listen to or something like that the ApplicationExit event occurs too late.
thanks!

Hi,
you can use MDI child's FormClosing event, where you can also cancel MDIParent from closing:
private void Form2_FormClosing(object sender, FormClosingEventArgs e){
if (e.CloseReason == CloseReason.MdiFormClosing)
{
e.Cancel = (MessageBox.Show("My MDI Form is closing. Do you want to close me ", "MDI Closing", MessageBoxButtons.YesNo) == DialogResult.No);
}
}
There are quite a few Closing Reasons you can react to differently...
