Re: about static member
When you define a static class variable like this, you need to actually
declare the variable.
So, in your CPP file, you'd put something like this:
static CSession Test::session;
In the case of static CDataSource, I'm not even sure what this does. You've
specified a type but declared no variable. ???

Hello!
I have a class lets call it Test see below.
In this class I have two objects of type CSession and
CDataSource.
I want to be able to access these two from the class itself and not from
the instance
so I tried to declare them as static in the the class Test
But when I do so I get the following link errror.
AlterObj.obj : error LNK2001: unresolved external symbol "public: static
class ATL::CSession Handle_DS::Session"
(?Session@Handle_DS@@2VCSession@ATL@@A)
ReleaseMinDependency/DTHToolObjects.dll : fatal error LNK1120: 1
unresolved externals
As you can see I can declare CDataSource as static but not CSession
So I just wonder what I can do to access CSession from the class itself
and not from the
instance ?
Why is it not possible to declare CSession as static ?
class Test
{
...
static CSession session;
static CDataSource; //This works fine
...
}
