Circular Maze Generator

[SierraKen]

Here's a circular maze generator I made today. I figured this kind might be easier to make and it was.. sorta. lol. The walls aren't the best but it's the best I know how to do. Tell me what you think and enjoy it. Also put it in its own folder to save mazes as bmp pictures. I might make a JPG version later on but I'm out of energy. lol You can make colorized versions or black and white (to print).
Attached is a color version I made. Oh also, you cannot print the colorized version because it would take too much ink or toner. I set it so it would be impossible to within the app itself.

- Deleted the code until I fix it...

I fix your walls:

Thanks B+!!!! I just have one more problem though, it's not saving the right picture, instead of the first one it's saving the next one it makes after you give it a name. Can you help me with this too? It always takes me at least a half an hour or more to find the right areas to put the _PUTIMAGE and SCREEN, etc. even though I've made these before. It's like a puzzle to me every time. lol Oh and I do agree, I'll stick with just the black and white, the colorized walls were too dark to see that good. I also agree with just having the Hard setting.
Here is what I have so far.. there was 2 conflicting lines as well that I put on accident in the DO Inkey$ LOOP area, so I removed those.

Hi Ken,

Remind me what line 36 is doing.

Seems to me you can just draw the picture and then save it, no need to switch between image pages.

For printing, I guess you need to transfer to an image handle to turn page but do that in the printing part of code.

[SierraKen]

LOL B+ you just saved the day again! I switched it from s& to picture& and now it works! I also cleaned up all the unnecessary code so I believe this might be good! Thank you!

Ahh, maybe I can do without switching, I haven't tried that. I am just glad it works as it is.

[bplus]

LOL, what's the saying? If it works don't fix it.

[SierraKen]

Well I got bored... lol... so I saw if you were right and you were, I didn't need to use switches. Here is the updated code with just 1 (besides the printing code).

and it's OK with printout?

Never mind I found the printer section and it does it's own thing with image as it should.

[SierraKen]

Yep, I didn't touch the printing code. But I did check to make sure I was using the right one for the printing code. I tested a few on my printer.

[SierraKen]

I just used Steve's 2 JPG libraries that he posted the other day and now this saves as a real JPG picture! My first ever! Thanks to all of you guys for the help! I will include the 2 library files that should be in the same folder as this .bas program (I believe). I'll also mention it in that JPG libraries forum thread. Included in the attachments is also the .bas program.

Thank you!
