Hi,
I have a DarkBasic-Pro Application. If a user wants to end it and clicks on cross of the window the programm crashes. Is there any easy way to test whether the user tries to end the programm using standard-windows tools?

This is not standard behaviour for a DBP application. Are you using any plugins? It could be that if you aren't ending a plugin that requires it there might be a crash. One standard way around this is to compile the application as "fulldesktop" and give the user another way to end the app such as if they hit the escapekey it triggers a "Do you want to quit (y/n)?" event.



Untested and written on the fly but try it and see how you get on.

Hope that helps...

I'd hazard a guess that the program "opens" a file, but never closes it, or unloads it, or something along those lines.

Good point BFM that's another possibility!

Hi,
an error in my coding, thats sound like a very probable option. Is there an easy way, to see all open file handles?
My other question is, I load some bitmaps using load bitmap,
copy it to another bitmap and use the same bitmap number again to load a new bitmap. Should I delete each bitmap before reloarding?

Shouldn't matter as far as I'm aware.

You can use the FILE OPEN() command within a FOR/NEXT loop to check all the open files.



If those bitmaps you're loading are just to grab the images with GET IMAGE you should use LOAD IMAGE instead. It does exactly the same as LOAD BITMAP with GET IMAGE... the only time you really want to use LOAD BITMAP is when you want to manipulate the image before using GET IMAGE.

There are also plugins like BlitzTerrain that require you to delete their assets before you exit, or it will crash on you.

But that doesn't sound like the problem you're having. Just thought I'd throw it out there.

Hi,
I extended Grog Grueslayer to loaded dlls.

However neither dlls are loaded nor files are open. Is there any similar way to test in a comparable manner for loaded plug-ins?
I have some questions regarding the difference between get image and load bitmap. I just load some png files and copy them together. Is it better to use the image or the bitmap functions. I choose the bitmap, but did not think about the difference between these two different function groups.

If you're doing something like this:


This is exactly the same thing:


Using bitmaps is just intended to set up menus/maps/whatever away from the view of the user so they don't see the image setup before it's done. Now if you're changing the image in any way before grabbing it then it's ok to use bitmaps.

The DLL EXIST is only going to tell you about DLLs that you loaded with the LOAD DLL command. Plugins are included in the EXE by the compiler and are always in memory when your program is running.

If you are altering the image in some way before you use it, then you can use LOAD BITMAP, but if you are just going to use the image unaltered then use LOAD IMAGE. It's faster.

For the program to crash by clicking on the Close button, there has to be something in use that DBPro doesn't automatically clean up when it exits. Probably something you've created or opened using a plugin.
