Answer 1

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

Hi,winLight

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

http://msdn.microsoft.com/en-us/library/system.windows.forms.application.exit%28VS.71%29.aspx

hope it is useful for u.

Answer 3

Jenifer,

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

Hi,winLight

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.
