exporting global from EXE to DLL?

Hi all,

I need to export a (dare I say) global variable from my EXE
to a DLL, but Visual Studio's linker seems to be blocking
this. Am I right in deducing that globals must be put
in a DLL and imported into DLLs and EXE from there? I am guessing
that the linker requires that info about the variable to be
in a .lib for it to be importable. In order to try the import,
I am using __declspec(dllimport) in the DLL, but the linker says it
assumes I really mean dllexport and is changing it to that,
then printing errors.

Thanks

 Create a seperate .lib  put your global in it

 then in your DLL and Exe

 extern g_blah;

 put the .lib on the link line for both.
