Application.exi t() vs Environment.exi t(-1) vs Application.exi tthread()

I am trying to close my application using Application.exi t() in the
frmMain_Closing event. When the form closes the process does not. My
application only has one form (no other classes either). The form has
a really long loop which generates approx. 700 .csv files. I do not create
any threads myself (Application.ex itthread() doesn't work either).
To counteract this I have decided to use the Environment.exi t(-1)
method instead.

What is the difference between the three methods?

Using environment.exi t() seems a strange way to do things considering there
is a Application.exi t method which claims to do what the Environment.exi t()
method does.

Well that's the first problem - you *should* me creating a separate
thread to do your main processing. You should test a flag in that
thread every so often to see whether or not you should exit, and set
that flag in your closing event.

method instead.

Application.Exi t is to do with message pumps - it effectively means
that Application.Run (...) will return at that point.

Application.Exi tThread is similar to Application.Exi t, but only for the
message pump on the current thread.
Using environment.exi t() seems a strange way to do things considering there
is a Application.exi t method which claims to do what the Environment.exi t()
method does.


No it doesn't. How is:

<quote>
This method stops all running message loops on all threads and closes
all windows of the application. This method does not force the
application to exit.
</quote>

the same as

<quote>
Terminates this process and gives the underlying operating system the
specified exit code.
</quote>

? Where is the claim you were talking about?

Hi. I'm pretty new to C# so this may seem like the dumbest question today, but I'm stuck. I have a small application, one Form that opens a connection to a database in its constructor. If the connection goes wrong I display a messagebox and I want the application to end after the user clicks OK. I cant make that happen..... If I use Application.Exit in my constructor the form still lives, if I do a this.dispose the program crashes and...

What is the difference from Application::Exit()? Does Application::Exit() terminate only the main thread and background threads, and not the foreground threads?
