Warning popup before closing MS-DOS window

praboonapraboona Posts: 1Member
Hello Everyone,

I have an application which runs on MS DOS.
While it is running, if I accidentally click on close button on top right it gets closed immediately.

Can anyone help me in creating a warning popup before closing the DOS based applications.

Awaiting an earliest reply.
