Hi all

I have the wrong result orpart of the program cannot work when using "start without debugging"in Debug Configuration in VS2008+IVF11.1.060. Then I run the programin Release Configuration, whichhad the same result asin Debug. But when the program used "start debugging" in Debug Configuration, it worked correctly.

So what is the difference between "start debugging" and "start without debugging" in Debug Configuration? What should i do?

Any help would be highly appreciated!

Best regards

Jack

Jack,

Check for uninitialized variable usage.

Starting with Debugging may present your program with different "junk" than starting without debugging.
Do not assume uninitialized variables are 0 or 0.0.

Hi Jim,

Thanks for your reply!

I find my mistake in the program. There is an uninitialized array.

Best regards

Jack
