Error At 0x%08X - C Board

error at 0x%08X

I open up my program with a binary editor and a found about a dozen mesages about bad stuff happening at 0x%08X in the program now my question is where is 0x%08X in the memory stack and how would i find it useing VC++6.0.

> where is 0x%08X in the memory stack It isn't anywhere, this is just a printf formatting string At run time, if there is an error, the code will format whatever value is appropriate as 8 hex digits, with a leading 0x.

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut. If at first you don't succeed, try writing your phone number on the exam paper.

So if there is an error there what would that mean and why would that be described as a location. My program is windows based useing direct draw and i haven't used printf in my program but stdio is included. I am useing of streams though here is the entire mesage: with debug mode on: [email protected]\chkesp.cThe value of ESP was not properly saved across a function call.

oops i though it would just wrap around

> and i haven't used printf in my program That doesn't mean the run time library can't use it.

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut. If at first you don't succeed, try writing your phone number on the exam paper.

okay a few more questions: first i think there is something special about 0x%08X because that was used in the section on directX debging in sunlights tutorial. second why cand visual c++ put the error mesages in a more rational place then the EXE file(it was just by chance that i happend to look there).

> first i think there is something special about 0x%08X Probably not - though it usually means that you've done something horribly wrong. > second why cand visual c++ put the error mesages in a more rational place then the EXE file Where else would they go? I mean, for things like R6028 - unable to initialize heap You can look these up in the help. Without seeing the EXACT text of the error message you got, it's hard to tell you how to go about debugging such things in future.

Its about as close to exact as you can get. I was just wondering if the program used that message say as a generic error message for something or if it was just taking up space. At any rate i think ill just restart my progam from scratch and think of the last one as a learning experiance. Oh and thanks for the help.
