Global CList

Hi there,
Is there a way to declare a global CList??
If yes, how do you declare this CList in other modules??
eg.
struct myStruct{
           CString var1;
           int var2;
          };

CList<myStruct,myStruct>list_struct;
CList<CString,CString>list_str;

so in this case, how do I declare these 2 list in other "*.h" files?
I am using MSVC++ 4.0

Thanks.

Just like that - but put an extern in front for the .h

ie in the other .h files,

extern CList<myStruct,myStruct>list_struct;
extern CList<CString,CString>list_str;

That should be it.

In the defining .cpp you would have these lines WITHOUT the 'extern' in front - that then make the line a 'definition' instead of a 'declaration'.
