Problem in desktop application

Kanhialal, please define "it does not work". What do you mean by that? When you say "it does not work", it sounds vague. We don't know what the problem is; we cannot understand. We need some clarification somehow. If the problem is that you don't see anything; that the image does not show, then it helps to say that. If the problem is that you don't see an image and there is no error message or any other indication of error, then it is unlikely we can help. You need to debug the program. The only other advice I can give is to ensure that your program is catching all possible errors. It might be that there is an error that your program is ignoring. If your program does not ignore it and instead shows you the error then you might know exactly what the problem is.
