hi all
i am using a .lib in my application and there is function that i call which reads a file and fills some structure variables. variables can go in thousands. when i run it is throws an exception saying
"Windows has triggered a breakpoint in ConsolTest.exe.
This may be due to a corruption of the heap, and indicates a bug in ConsolTest.exe or any of the DLLs it has loaded.
The output window may have more diagnostic information"
what could be going wrong

Heap corruption caused by a lib function

Ah, I understand. Then maybe the compiler options are different. Check the following option in Project Properties:
Configuration Properties\C/C++\Code Generation
Runtime Library
The runtime library should be the same for both the static lib and the project that uses the static lib. You can use any option you like here just made sure you have the same option in both projects.

Actually I already have compiled that with the VC++.NET 2005. But the problem remains there. I dont know what is heap corruption.

I actually made the lib with VC++6 and then built the project with the VC++.NET 2005. The lib is starting the function well. Here i put the call stack trace. at the bottom is our function which causes the problem. I dont know what is going on after that.
