Heyho
I follow the tutorials from rastertek.com. I'am at Lesson 22 and tried to change my engine to release mode the first time.
Now my problem: my engine works in VS 2010 debug AND release mode.
BUT: When I start the executables in my engine-folder, the debug one is fine but the release one not.
On the right side of my spinning cube, a triangle is sometimes missing (black) and also the whole backside is lost... And I don't know why...
And why does the problem just occur, when I start the executable and not when I start it in the Visual Studio?
Could anybody help me?

Could anybody help me?

Just as seabolt said, this is most likely due to e.g. some member variable not being initialized in the constructor. I'd recommend getting yourself a static code analysis tool like cppcheck. Then you can scan your source files, and it will tell you all appearences of unitialized memory (as well as other issues).

Okay thanks for your hints so far...

I downloaded cppcheck and now I'am solving the tons of warnings (many member variables not initialized in the constructor)

Also in debug compile with warning level 4 and set treat warnings as errors, this will most of the time avoid you having extremely annoying release run issues.

How can I debug with warning level 4?

Find your directx control panel and make sure that you're getting all of it's output and see if you're failing anywhere or any warning that DX maybe saving your from.

How to use this DX Control Panel, or is it self-explaining (I didn't try it yet)?

...

If people were using debuggers correctly, programming forums (like GameDev) wouldn't have tons of unnecessary threads where people ask why something doesn't work as expected, including hundrets of code lines for other people to read and find the error.

Knowing how to debug your own program is maybe the most important skill of a programmer. I really don't belive that you are able to write bug-less code directly from your head.

I honestly don't know whether your post isn't just a joke or a trolling attempt, because it sounds so. Or you are maybe making just very small and simple applications.

Besides the other advises from people (not Norman), I would also suggest you this: in the future, verify your code in both modes more often, not just when it's all done. If you know that your application was running in release mode at the end of the previous day and today it doesn't, then you just need to remember what you've added or changed today. (Of course you can go from days to hours.)

I will do it in future. But your advise doesn't help me today..

I will write again when I got rid of all the warnings from cppcheck...
