In my project which is mfc but linked codejock as static lib and in my project which do not have view class and every thing it doing in the child frame class.  I had a lot crush cause by dc.m_hDC = NULL.  Any idea to fix this quickly?

 

Thanks in the advance.

Child frame should have some internal content - usually created in virtual BOOL OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext);

Do you have one?
e.g. in my sample used new MS FeaturePack I use it this way as like to have calendar and datepiker in one child frame but you can eliminate splitter and create only calendar control here

 

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
 BOOL bRet = TRUE;//CMDIChildWndEx::OnCreateClient(lpcs, pContext);

   if (!m_wndSplitter.CreateStatic(this, 1, 2))
    {
        TRACE0("Failed to create split bar ");
        return FALSE;
   }

 VERIFY(m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CCalViewNew),CSize(200, 200),pContext));
 VERIFY(m_wndSplitter.CreateView(0,1,RUNTIME_CLASS(CDatePickerView),CSize(200, 200),pContext));

 bReady = TRUE;
 
 CMainFrame* pMain = DYNAMIC_DOWNCAST(CMainFrame, AfxGetMainWnd());
 if (pMain)
 {
  CCalViewNew* pCal = DYNAMIC_DOWNCAST(CCalViewNew, m_wndSplitter.GetPane(0,0));
  if (pCal)
   pCal->m_CalendarController.SetDatePicker(pMain->m_Picker);  
 }

 return bRet;
}

 

Another approach - create calendar in dialog - there is sample how to implement it (look in Forum - there is a link to my recent source)
