Hi

I created C# project ,but there is problem,the problem is if I click on close button in right side upper corner in windows application while program is running ,then it's close,but I cant compile it in second time because its giving error massage "your Test10.Exe is already running",but there is no Test10.exe running,so what I am doing is I close it from task menu. In task menu it show "Test10 " as running process.What is problem with in coding?.In .NET framework it automatically destroy unwanted objects.Please Help me

Thanks

Show us your code. You cannot repair a car when the engine is broken and the hood is closed.

Closing a window doesnot close or terminate an application. Problem shows that your main thread or main window form is still running with hidden state.
However if you want to terminate an application handle the FormClosing event and add following:

Application.Exti();

Here is coding.Column and SheetFormat are class.

Hi

Thanks adatapost for quick reply.I will try that.

Tank50

WorkSheet.... because you use COM, which you didn't terminate it yourself and if you open the task manager you will see Test10.exe is running. Try adatapost help it solves your problem

I think Ramy has the answer here but I also have this happen randomly when everything has been cleaned up properly -- the issue turned out to be the visual studio hosting process. If you go to your project properties then on the left side click debug, the bottom most checkbox defaults to true for "Enable the visual studio hosting process" -- uncheck this for release and debug builds. I turn off the VS hosting process for all of my projects.

Hi

I did what adatapost is saying ,now it working properly.

Thanks
