Press ESC button and then press Exit. Let me know if that works (I will explain the reason, if that is the case).

And yes, use reply link to reply to the comment or I don't get a notification.

Solution 1

I think that your code that sets 'cancel' to true, is running both times, which means that your app can never close.

Thanks christian. But when we call Application.Exit it will not go to form closing event. And on button click we can not set e.cancel=true.

Help me if you have better answer.

Hi sunder.tinwar,

In the Form_Closed event handler use this code :

Application.ExitThread();

I hope this help,
:)

Hi michael thanks for reply but I figured out why its happening is I am starting lot of threads from my appliation. When I am closing applicaiton I need to close my threads manually then every thing will go fine for me or use Environment.Exit
Anyhow thanks.
