How can I do this?

Briere,

You should really examine the sample code that accompanies the DGDk. But basically, your main entry function DarkSDK() should contain a while loop:

+ Code Snippet

void DarkSDK( void )
{
  while( LoopSDK() )
  {
    //  Test for a quit condition
    if( dbEscapeKey() )
      exit;

    ... other code ...

    dbSync();
  }
}

I know but sometimes I need to kill the application before that main loop is completed.

Completed? That loop should always run for the life of the application. It should only terminate when you want to quit, hence the Escape Key test.

Yes I know, but there are numerous other loops, and a few processes that take some time before the main application loop completes. The idea is for my error handler to kill the application before it freezes or gets all whacky on the user.

Ahh I see, you should use exception handling

What does LoopSDK do?
Take care of the windows stuff?

[EDIT]
This is why I want to kill it right away.
I do the set up before the main loop of the program, and if the settings files are corrupt or missing, it will cause the user to have the need to restart their computer.

LoopSDK handles all internal DarkBASIC system stuff like playing animation files, music and sound etc, although you would normally have your dbSync call inside this while loop as well. The while loop is your main game loop. Ideally, when your application needs to terminate, all you do is exit this loop so that the DarkSDK function terminates.

What you could try and do, is sub-class the main DBPro window, and, in that messaging loop detect a WM_USER command, which would then send a PostQuitMessage, or something like that.

Come to the last Unofficial DBPro Convention (http://convention.logicstudios.net/)
Dont do anything I wouldn't do. But if you do, take pictures.

Yes, I think you should use exit;, or even return; instead of Application.Kill(); in order to be sure that all the cleaning is properly done.
