Which is the appropriate one to use in the above choice?
VB.Net. .Net Framework 1.1
Thank you,

As far as I know both should be avoided unless you have a specific

My understating is by calling the above statements will close the
application properly. Like releasing all the resources....  etc.

That is the reason why I am calling the above statements.

Both will release resources, but custom cleanup code may not be executed!
Could you describe the design of your application in more detail and where
you are calling 'End'/'Application.Exit'?

Application is basically gets the data from the database and prints in a
particualr format. When the user clicks the "Exit" button or "X" on the
right top of the windows form, the application will close.

Simply call 'Me.Close()' inside the form instead of calling 'End' or
'Application.Exit'.

If the .Net version of 'End' works anything like the VB6 version, use
anything else. In VB6, sure, it stops the app but in a way that's similar to
shutting your car off while driving. iow, it "yanks the plug" on the app,
possibly leaving automation objects hanging around waiting for task manager
intervention.

What do you do if you start you application from a sub main and open a form
within sub main?

You close the form (Unload Me).

<shame> Oops... I had a VB.Classic flashback.... it's Me.Close. Just like H.

Pete,

In C# (and other languages) is used a Shared Sub Main as starting point of a
program

In VB Net as in VB6 you have the choise between using that Sub Main or using
the inbuild one in your main-form. (Herfried uses forever that Sub Main in
his samples, I use forever that MainForm (form1).

You would never use End for the reason as Ken Halter has explained.

With a Sub Main you would use
application.exit

With a mainform you would use
me.close

I hope this helps,

Cor

Hello group,

Let me give my opinion about how to properly close a Windows Forms application:

If you haven't a Sub Main, that is, your starting object inherits from System.Windows.Forms.Form, you should finish by closing the main form. You can use Application.Exit (or ThreadExit) or even Environment.Exit, but it won't fire events like Closing or Close.

If you have a Sub Main, you can use Application.Run to start one or more consecutive message pumps. You can do it in two ways:
· Using Application.Run(): You have to quit from the message pump by executing Application.Exit (or ThreadExit if you use multiple threads). The inconvenient has been noted above.
· Using Application.Run(ApplicationContext) or Application.Run(Form): This way you work just like when you have one main form: closing the form will finish the message pump. Additionally, if you use an ApplicationContext you can change the ApplicationContext.MainForm at any time, efectively changing your application's main form (the form that will end the message pump when closed). You can still use Application.Exit or ThreadExit to quit without invoking further events.

Regards.
