have you looked at file stdafx.h?

OmarSH

what should i looking for ? in "stdafx.h" file??

dusty_dex

Well are you using an external C library? Your error is with the linker, and the function name has been mangled by C++ because somewhere in your code there should be

#ifdef __cplusplus
extern "C" {
#include ...
#endif
.
.
.
#ifdef __cplusplus
}
#endif

Not likely to be stdafx.h but I thought it worth asking because it's related to stdafx.obj :)

No, this is the error from the Linker; you need to understand the difference.

ok guys i am beginner ,what should i do exactly to solve this error ,even i don't know what is the linker ,

We need to see some of your code to be able to figure out what is going on. The first message implies that there is some confusion between c and C++ code in your project. The second message suggests that you have a call to a list destructor in your code. For information on the linker (and building programs in general) see http://msdn.microsoft.com/en-us/library/91621w01(v=vs.71).aspx[^].

I am not sure what you are saying here, but it may be that you need to do a Clean and Rebuild of your project(s).

No, this looks like the debug window of Visual Studio when you are trying to execute your program. You really need to go to that link I provided for you, and learn and understand how programs are built and executed, and the differences between the various phases of that process.

Is the list object being referenced yours or the one from the STL? If the former, it's missing a destructor.
