Can I assume that CRatiosWin is not getting deleted in this segment of code?

virtual int ExitInstance()
{
   if (m_pMainWnd)
   {
      m_pMainWnd->DestroyWindow();
      m_pMainWnd = 0;
   }
 
   return CWinApp::ExitInstance();
}

why don't you just pass the parent pointer to the ChildDlg when it's created and check the GetParent against that pointer ?

class IMyTypeInfo 
{
public:
  virtual int getType()=0;

class Dlg1 : public CDialog, public IMyTypeInfo
{
public:
 virtual int getType(){return 1;}

class Dlg2 : public CDialog, public IMyTypeInfo
{
public:
 virtual int getType(){return 2;}

class Dlg3 : public CDialog, public IMyTypeInfo

int iType = ((IMyTypeInfo *)GetParent())->getType();
