Double confirmation on exit
Question
I am trying to make it so that the user is prompted to confirm exiting my program in c#, but for some reason, if they say "yes" they would like to exit, the confirmation box would pop up again. I can't figure out why.
if (MessageBox.Show("Are you sure you want to exit?", "Confirm exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
{
e.Cancel = true;
}
else { Application.Exit(); }
Solution
Ah, did you check the CloseReason
for the FormClosing
event? I think you might get the same event for two different reasons (although I don't exactly expect that to happen normally); check your FormClosingEventArgs
to see what the parameters are.
OTHER TIPS
Use this
private void frmMain_FormClosing(object sender, FormClosingEventArgs e)
{
if (MessageBox.Show("Are you sure you want to close?", "Infomate", MessageBoxButtons.YesNo) == DialogResult.No)
{
e.Cancel = true;
}
}
Ah, I figured out how to fix it. I removed the Application.Exit(); event from the FormClosing event, and moved it into the FormClosed event. It all works now.
