illegal reference to non-static member

I am trying to refer to a cstring mycustompath from a different class from my current class.

CString test = CBar::mycustompath + _T("executables\\IECapt");

But I got this error instead:

error C2597: il开发者_如何学JAVAlegal reference to non-static member 'CBar::mycustompath' c:\work\b.cpp 14

How to fix this?

This means that mycustompath is a property of a specific CBar object and not a property of the CBar class. You'll need to instantiate a CBar class

CBar* myBar = new CBar();
CString test = myBar->mycustompath + _T("executables\\IECapt");

or reference one you already have or, if mycustompath doesn't vary by CBar object, you can change it to static in the class:

class CBar
{
public:
    static CString mycustompath;
}

This indicates that CBar::mycustompath is not a static member variable of CBar. You will have to create an instance of CBar to access it:

CBar bar;
CString test = bar.mycustompath + _T("executables\\IECapt");
