I just downloaded DekeD 3D editor lite, but everytime i click somewhere with a mouse an window appears with the message:
"Acces violated at adress 00000000. Read of adres 00000000. "
I cant do anything cause everytime i click ok, a new window appears with the same message.
What do I have to do?
Sorry if my english isn't very good. |

Hi there Tomto,
Welcome to these forums, we are very sorry you are experiencing these problems.
1. Try re-downloading and re-installing the software. Make sure you download the installer, not the stand-alone executable.
2. Make sure you are on the latest version of your graphic drivers. Faulty drivers are the #1 cause of these problems. Even drivers a month old can contain bugs that cause exactly this problem.
If that doesn't solve things, please provide us with as much details about your system as possible
- What OS are you on?
- What videocard do you use?
- Did you install the application in any other location than was suggested by the installer?
- Did the installer throw any expections?
Any information you can provide is much appreciated. We really really want to get this particular problem nailed down! |

As a suggestion: You could add a structured exception handler at the top of the program (WinMain), which contained the following information:
Type of exception
GL renderer string
Version of Windows
Install path
Number of files and folders in the install path
When people post the error message, you'd be a lot closer to solution already :-)
Other improvements include the ability to write a mini-dump (for post-mortem debugging), and the recognition of bad graphics drivers and Windows versions up-front, giving a user-friendly dialog box. |

Yeah, something like that could be real useful, but we really keep hoping there is just one major issue, and once we clear that one up there is no need to confront the user with all that techinical fluff  J/k ofcourse.

If we knew how to recognize those bad graphics drivers I think we'd have our problem solved  . Do you by any chance know an application that allows you to simulate poor OpenGL support (i.e. some sort of replacement opengl dll, hooks or similar)? |

I just look for the gl renderer vendor string, and disallow anything with "microsoft" in it. That takes care of 90% of the bad cases. Other things you might want to look for and warn about include "matrox" "sis" or "s3" -- case insensitive, of course. (On this subject, note that "nvidia corporation" actually contains the "ati" substring :-)
When you see "microsoft," it means they don't even have real drivers installed, so just post a dialog to the effect that they need to go get real drivers, with some suggested URLs. |

What about the MS OpenGL 1.4 emulated through DX9 driver?

| I wouldn't want to support that driver. It means users haven't installed the right drivers from the vendors. |

That might be their only driver option, and it offers full hardware opengl 1.4 support. What's the problem?
You should just check for the version info. 1.1 means you have no proper drivers, and are using the old MS opengl.dll. If the 1.4 implementation will get the job done, don't discriminate against it.
For all we know, that dx layer might work better for those users than some of the bastardized 'right' opengl drivers on Vista. Trust me, there is nothing 'right' about my current opengl driver.  They came with a disclaimer that they might not be suitable for accelerating 3d graphics. 
Meanwhile dx works fine, and I imagine that the dx layer would negate some of the gdi + opengl hiccups, artifacts, and bad behaviour that now plagues DeleD.

| Thanks for the suggestions, guys. All this would have been solved by long if we had a battery of testing machines here with crappy video support, but for some reason we keep buying these shiny machines with the latest and greatest polygon-pushing techniques installed... poor us. If you have any tips about emulating bad driver support (besides 'installing vista' )... |

I think we should have that kind of information (except the exception info) in some sort of General Info dialog box under Info menu anyway. Should be easy to build and could help us out solving problems right away. |

You could download and install one of those "old" graphics drivers to test out what you are working on. Then, you can revert back to your "latest and greatest" drivers after you finish.

Trucker: My thoughts exactly, but for some reason I can't find a download site for severely broken NVidia drivers... 
Daaark: Tried it. I am actually typing this from a DOS prompt now, through a telnet 80 session.
[Update]While doing a rollback on my NVidia driver I am now in a situation where all of my OpenGL support is down the drain and I can actually reproduce at least some of these problems. Yahoo. Kinda.[/update]

While waiting for machines to reboot, this thought occurred to me:

| It's like lending your car to a friend, then having him complaining how it crashed on him while he drove it out of the driveway. It could be anything: the breaks, the windshield, the gearbox... but usually it's just a bad driver. |
I consider myself pretty funny. Then again, I haven't had my morning coffee yet, so perhaps I shouldn't be posting on public forums right now. |
