Can't implement vector of CTreeCtrl or CWnd

[ardentfreaker]

Hi,

I am not able to add an item to a vector of type CTreeCtrl. This applies to an item of type CWnd in general.

vector<CTreeCtrl> v;
CTreeCtrl obj;
v.push_back(obj);

throws an error :

Error 1 error C2248: 'CObject::CObject' : cannot access private member
declared in class 'CObject' C:\Program Files\Microsoft Visual Studio
8\VC\atlmfc\include\afxwin.h 1820

Vector of strings or other regular items works fine.

Please let me know if you know the answer to the same.

Thanks,
Hemanth

Searching google for "cannot access private member declared in class 'CObject'" will tell you everything you need to know.

Try this as a simplified explanation.

CTreeCtrl obj1;
CTreeCtrl obj2;

obj1 = obj2;

Try this as a simplified explanation.

CTreeCtrl obj1;
CTreeCtrl obj2;

obj1 = obj2;

hello
you can,t copy two instance of class directly to each other, see this:
