Migration to VC7: CString problem

[Ram Baruch]

Hi,
In my company we're trying to migrate our application
from vc6 to vc7.
in one of our dlls we define the following class:

class __declspec (dllexport) CExString : public CString
{
....
}



and everything is ok until one of our functions, for
example:

void ExportCExStringFunc(CExString& someStr)
{
....
}

is EXPORTED from the dll.

The linker doesn't accept this and we get tons of errors
in the project that IMPORTS this function.

When I changed the class to something like:
class __declspec (dllexport) CExString
{
CString mStr;
}

it was ok, but then, of course, I have differnt problems
and it is not exactly what I wanted.


Does anyone knows something about it?
Thanks,
Ram.
