VB.net Application not exiting completely

Hi, the application I am developing does not exit completely. i.e. the process can be seen in the Task manager. This happens only when I click on the [X] button on the title bar of the window of my MDI form. If I use the File >> Exit in the menu of my application, it exits without leaving any traces. I have used the "End" method there. But the process stays when I click the [X] on the control box on the title bar.

Thanks in advance,

Never use the End method. 

It kills an application, giving it no chance to clean up.

Simply use for the close the close and nothing more.

(The x button does that automatically)


Answer 2


what i think is that if u just click [x] button, it only causes the form onload, and it won't make the application stop.

what to do is u can try use Application.exit() method

here is a link regarding the application exit issues, may be u wanna read it


hope it is useful for u.


Answer 3


To use the application exit is only a good idea if you have started your program with Application.Run, both application Run and Application.Exit are done in most windows programs by the application framework, so it is seldom a good idea to use that.

Despite that some do.



Answer 4


There is a Shutdown mode in the properties of application in VS

Right click your project name->Properties->Application tab->Shutdown mode

two options for u to choose:

1. when startup form closes

2. when last form closes

Choose one base on the specific requirement.
