In C++ Builder 6.0 it is possible to create shared data segments in a DLL. I use it for a Windows
Hook procedure. I have my test software in 2 versions. The first one is made with VC++6.0 and I use 
the way you described

>A have read that for MSVC++ the right method is to use #pragma like this :
>#pragma data_seg("SHARED")
>int MyInt;
>#pragma data_seg()
>#pragma comment(linker, "/SECTION:SHARED,RWS")

In C++ Builder 6.0 I use the way you described too:

>Then, I have found that for C++Builder4.0 the right method is to use #pragma like this :
>#pragma option -zRSHSEG      // change default data segment name
>#pragma option -zTSHCLASS    // change default data class name
>int MyInt;

It is important the shared data are in a seperate file. Check out this:

If you make your DLL with the shared data in the way the technical note shows this you will have your 
DLL with a shared data segment. I have not check if this way works with BCB5, but it works with BCB4
and I did it with BCB6.
