Close [X] aplication issue

[Rabelo]

Hi!!

I have a MDI aplication that has MDI windows and top windows and unfortunately the document interface is not implemented. When I press the X button on the aplication (not on the child frame) I need to save all modified documents on MDI and on Top Windows, but before save the documents and close the window I need to get the name of the file that is on the view.

The problem is that I cant get acess the all views from the childframe. In OnClose on the MainFrame I made a while to acess all views and get the file name but it is not working. I have tried get the view form several messages like GetActiveView() GetWindow() and send message (WM_SETFOCUS) from all possible ways. (If I get the focus on the view I can get the filename.) nothing is working. What is Wrong?

I wrote on Onclose of the MainFrame:

void CMainFrame::OnClose() 
{
  
  int Maximized(0);
  CMDIChildWnd *CW(MDIGetActive(&Maximized)),*PrimCW(CW);

  while(CW) 
  {
     //--- none of these is working.... ----------------------------------------

    CW->GetDesktopWindow()->SetFocus();
    CW->GetDesktopWindow()->SendMessage(WM_SETFOCUS);
    CW->GetWindow(WM_SETFOCUS);
 
    ///--------------------------------------------------------------------------

    CW->SendMessage(WM_CLOSE);   //--- Ok but I don´t get the file name.
    MDINext();
    CW = MDIGetActive(&Maximized);

    if(CW == PrimCW) CW = NULL;   
  }
  
  CMDIFrameWnd::OnClose();
}

Thank you

Have a look at ths code snippet from MSDN (https://msdn.microsoft.com/en-us/lib...activedocument ) :

   CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->GetMainWnd();

   // Get the active MDI child window.
   CMDIChildWnd *pChild = (CMDIChildWnd*)pFrame->GetActiveFrame();

   // or CMDIChildWnd *pChild = pFrame->MDIGetActive();

   // Get the active view attached to the active MDI child window.
   CMyView *pView = (CMyView*)pChild->GetActiveView();

I did:

  int Maximized(0);
  CMDIChildWnd *CW(MDIGetActive(&Maximized)),*PrimCW(CW);

  while(CW) 
  {
    //-----------------------------------------------------------------------------------------

   CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->GetMainWnd();

   // Get the active MDI child window.
   CMDIChildWnd *pChild = (CMDIChildWnd*)pFrame->GetActiveFrame();

   // or CMDIChildWnd *pChild = pFrame->MDIGetActive();

   // Get the active view attached to the active MDI child window.

   CView *pView = (CView*)pChild->GetActiveView();

   ((DesSecaoView*)pView)->SendMessage(WM_SETFOCUS);    //--- dont work

   ((DesSecaoView*)pView)->SetFocus());        //--- dont work

//------------------------------------------------------------------------------------------
    CW->SendMessage(WM_CLOSE);
    MDINext();
    CW = MDIGetActive(&Maximizada);

    if(CW == PrimCW) CW = NULL;    //---  buffer circular.
  }

And the SetFocus message dont get to the view...

I did:

  int Maximized(0);
  CMDIChildWnd *CW(MDIGetActive(&Maximized)),*PrimCW(CW);

  while(CW) 
  {
    //-----------------------------------------------------------------------------------------

   CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->GetMainWnd();
   CMDIChildWnd *pChild = (CMDIChildWnd*)pFrame->GetActiveFrame();
   ...
   CView *pView = (CView*)pChild->GetActiveView();

   ((DesSecaoView*)pView)->SendMessage(WM_SETFOCUS);    //--- dont work
...
  }

And the SetFocus message dont get to the view...

Sure it doesn't! Just because the WM_SETFOCUS is a notification message! See https://msdn.microsoft.com/en-us/lib...(v=vs.85).aspx
To set a focus you have call the SetFocus API or MFC Cwnd::SetFocus method.
