Class member initializations

My compiler refuses to compile this code because of "ISO c++ forbids 'in-class initialization of non-const static member `ExStyle' ' How can I bypass this? Using Dev-cpp on Windows

Thanks.:)

here's the code:

Code:

---

#define _WRAPPER_H
class Window
{
HWND hwnd;
      public:
            Window();
            virtual ~Window();//and this
            HINSTANCE hInst;
            DWORD ExStyle=0;
            int  width=400;
            int  height=300;
            int  X=400;
            int  Y=400;
            HWND Parent=HWND_DESKTOP;
            char* name[];
            char* WndClass[]; //Ugly
            DWORD style=WS_SYSMENU;
     
      hwnd=CreateWindowEx(ExStyle,
                          *WndCls,
                          *name,
                          style,
                            X,
                            Y,
                            width,
                            height,
                            Parent,
                            NULL,
                            hInst,
                            NULL);
      };
     
};
#endif

Data members of a class are initialized in the constructor. You're not allowed to give data members a default value before the constructor is called unless they're static (ie. they belong to the class as opposed to objects of the class). You also have public data members, which is a big no-no, and your arrays lack the required sizes, and you try to call a global function in the class definition outside of a member function? I see a mismatched brace, and _WRAPPER_H stomps all over the implementation's namespace.

This seems like an overly complicated attempt for someone who clearly has no idea how classes work. Might I recommend some simpler projects to become familiar with object based and object oriented programming?

Yeah I guess I should review my classes 101...
Thanks for comments.
