Visual Studio 6 had an Export Makefile option but as I am now using Visual Studio 2005 I cannot find this option, has it gone?
Does anyone know what is the method to generate a Make file if you wnat to port your code from Windows to a Unix platform?

by lot of R&D I find that This problem is occuring when I am calling
function with arguments i.e.
int function1(int arg)
when I callled the function without arguments no error is occuring
everything is fine i.e.
int function2();

If it is a general issue, i.e. event an empty function give troubles then your calling convention is wrong.
I think you may (if you don't like to post the actual code), at least, post a simple test code that fails on your system.

ok I am sending some piece of code
in my dll my function as follows
extern "C" __declspec(dllexport) void function1();
extern "C" __declspec(dllexport) int function2(int index);
DllMain()
{
}
void function1()
{
// some code
}
int function2(int index)
{
int somevalue
somevalue =index;
return somevalue;
}
now on my applcation.exe
extern "C" __declspec(dllimport) void function1();
extern "C" __declspec(dllimport) int function2(int index);
//function1()
CMyDialog::OnButton()
{
function1();
//no error
}
//Now I called function2()
CMyDialog::OnButton()
{
function2(5);
// Debug error that I already post
}

Why your function definitions don't match function declarations?
Should be
extern "C"
{
__declspec(dllexport) int function2(int index)
{
int somevalue
somevalue =index;
return somevalue;
}
}

I tried this sample.
But i am not getting error if i define just as
int function2(int index){ ...} why?

Because it is allowed.

Hello Everybody,
I too have a same problem.
[1]having a function ABC(arg1, arg2) in a dll that does not uses MFC.
[2]explicitly loading the dll (through LoadLibrary()).
[3]fetching the address of ABC() by using GetProcAddress(...) and storing it in appropriate function pointer.
[4]calling ABC() through the function pointer.
In DEBUG mode when control reaches the function pointer I get a MessageBox with following message :
The value of ESP was not properly saved across a function call.This is usually a result
of calling a function declared with no calling convention with a function pointer declared
with a different calling convention.
MessageBox does not appears in RELEASE mode.
Regards.

If it only happens in Debug mode and works correctly in Release then perhaps this compiler bug is causing it.
I believe it only effects VC2002 and VC2003.

Problem solved. !!!  !!!
I declared function pointer in following way :
typedef int (_stdcall *PFUN_ABC) (arg1, arg2);
PFUN_ABC pFunABC = (PFUN_ABC) GetProcAddress(hDLL, "ABC");
pFunABC(arg1, arg2);
Now works fine in DEBUG and RELEASE.
Thanks.
Regards.

Try changing your calling convention.
See if this works:
extern "C" int __stdcall Adddata(void* item);
