Run-Time Check Failure #2 - Stack around the variable 'cz' was corrupted.
What my this runtime error mean? Or what could it mean…
I had a working app. Compiled in VS 6.0 but now when I compile it in VS .NET this error happens.
Run-Time Check Failure #2 - Stack around the variable 'cz' was corrupted.
...and justice for all

This happens for example if you write to an invalid address.
Mostly this comes from something like this.
Code:
char buffer[3];
buffer[4] = 'c';
Then when freeing the Variable buffer when leaving the function-scope, it is stated that the stack around that Variable is corrupted, cause you wrote to invalid address.
Check your Variable 'cz'. I think somewhere you wrote something out of their bounds.
Hopen this helps,

I am in the exact same situation (start to womder if it was worth my while porting to .NET)
Is there a way to see what is around the variable on the stack?
The variable it is complaining about is a bool!

Hi, you have to increase the array size in your code. Array value will start from 0 , if you define char buffer[3] then only 0,1,2 are accessible you cannot access buffer[4] because you defined only 3 values.
char buffer[5] ;
buffer[4] = 'c';

Did anyone actually read the line:

And just because someone has an array in code they showed in their reply, doesn't mean the original poster did. What is it about CONVERTING FROM 'VS 6.0' TO 'VS .NET' that causes this error?

VS .NET detects errors which are not detected by previous versions. However, sometimes such errors do not crash the program. For example, code fragment shown by matze42, may be executed corectly, if another variable on the stack is overritten, and program does not use the variable after this.
Try to comment off different part of the function and execute it, to find code line which causes this message. If you still has problems, post code fragments here.

Do clean and than fresh build the project from scratch helps at times.

If only it would be that easy to fix stack corruption!
BTW, this thread is pretty old, and the issue was explained by Alex F (above).
