Ending a program while in Form_Load

[Dom]

How do I end a program while in Form_Load? I tried both this.Close(),
and Application.Exi t(), but neither will just end the program there
and then. Instead, both allow Form_Load to continue.

Well, I suppose you could just throw an exception, or just put a "return"
statement after your call to Application.Exi t(). That would prevent the
rest of your Load event handler from executing.

The Application.Exi t() method isn't like the old CRT "exit()" function.
It doesn't terminate the process. It just signals to the application
message pumps to stop and closes all the windows.

I'm not aware of a .NET equivalent to "exit()", though of course an
unhandled exception can terminate the application, albeit messily. You
should avoid implementing code that just terminates the process. It's
extremely unlikely that there's a good reason for wanting to do this, and
you're better off exiting your application cleanly.

Environment.Exi t() is *reasonably* close to exit() I believe.

Perhaps. The docs are extremely vague on exactly how it operates, but
yes...it appears reasonably close to exit().

Still, I wouldn't recommend it as a correct way of exiting a .NET Forms
application. :)

I'm not sure what you mean. The OP has made it very clear that he wants
to optionally continue with the program based on the user's response to a
_dialog_. I don't think there's any "maybe" about this hypothetical
splash form of which you speak.

On the other hand, if one is talking more generally about how to display a
splash form, sure...that's possible and wouldn't involve any conditional
stuff based on the display of that form. But I'm not sure how that'd be
relevant in this thread.

Pete got it right. I don't want the main form shown at all if the
user cancels from the dialog that comes before it. The dialog gives
the user the options that are available at the moment, none of which
may be appropriate.

Pete's solution worked fine for me.
