GRaceful way to exit a B3D application

Hi folks.

I've a little issue whereby using the 'END' command to terminate my executable sometimes results in a pop GUI stating 'program.exe has stopped working - Windows is looking for a resolution'. Whilst not a biggie - I'd prefer for it to just stop rather than Windows OS thinking that it has fallen over unintentionally.

Anyone had a similar problem?

Are you definitely sure it's End and not something you're calling immediately before it?

The closest problem I've had to that was a library that turned out to have an error in one of the DeInit functions, which were presumably more or less untested since nobody ever uses them mid-application.

@Yasha, thanks for the suggestion - I am using MikhailV's excellent FastImage - although I cannot tell if it is using this that randomly causes a memory exception.

Basically my 'quit' code hangs of a button at the moment:


			If mouseOverButton=8      ;quit
				If button$="Left"
					Bquit=1
					
					VWait 100
					
					End
				Else
					Bquit=0
				EndIf
			EndIf

As you can see, I stuck in a vwait of 100 to try and resolve the issue, it didn't work - I still get random crashes upon trying to quit.

I know the user is exiting the app anyhow - but it'd be nice to end the executable gracefully.

Is anyone aware of how to 'take down / terminate' a B3D program other than using the 'END' statement? Thanks.

End should work anytime for Blitz3D. You are probably not deinitializing FastImage properly.

@Floyd - thanks, I will look into my de-initialization of FastImage - I do not believe I am doing that at all currently - probably the root of my problem.

Anyone know how to de-initiliaze FastImage?

There is a DeInitDraw command that the FastImage documentation suggests calling before EndGraphics or ClearWorld. I would be surprised if omitting this before End was a problem, as commenting it out of the examples has no effect, but seeing if it fixes the problem is cheap, so...

tried the following:

			If mouseOverButton=8      ;quit
				If button$="Left"
					Bquit=1
					
					;trying to stop le crash
					
					DeInitDraw
					
					FreeEntity box_3d1
					
					EndGraphics
					
					ClearWorld
					
					
					
					VWait 100
					
					End
				Else
					Bquit=0
				EndIf
			EndIf

However still giving me a MAV upon quitting.

Is there a way I can capture what is causing the MAV and work it back from there?
