I'm trying to user DYNCREATE in my MFC Application, unfortunatly I get the following errors:
Error C2509: 'CreateObject': member function not declared in MainWnd
Error C2509: '_GetBaseClass': member function not declared in MainWnd
Error C2039: 'classMainWnd: is not a member of MainWnd
Error C2248: '_GetBaseClass': cannot access protected member declared in class 'CFrameWnd'

MainWnd is delcared as MainWnd : public CFrameWnd
and I have IMPLEMENT_DYNCREATE(MainWnd, CFrameWnd) in my implementation file and DECLARE_DYNCREATE(MainWnd)

Any help would be appreciated!

your MainWnd is private derived of CFrameWnd

class  MainWnd : CFrameWnd

just do this
class  MainWnd : public CFrameWnd

Sorry, its declared as MainWnd: public CFrameWnd, just an oversight on my part.

Do you have a creator and a destructor?

If you do not need one  declare an empty one :

MainWnd(){};
virtual ~MainWnd(){};

You have entered into deep troubled water of DYNCREATE macro. It shuld not be much of a hassle to come out of it.
Somehow your MainWnd () class is not able to find it parent window i.e. CObject because thats where DYNCREATE macro are implemented. Just go thru ur code and try to trace if you can reach back to cObject. Hopefully that shuld sole ur problem
The way its implemented is

CRuntimeClass * pRuntimeClass = RUNTIME_CLASS (CYourClass);
CObject *pObject = pRuntimeClass->CreateObject ();
ASSERT (pObject->IsKindOf (RUNTIME_CLASS (CYourClass));
