Getting a document pointer

I have a MDI app (Visual C++ 6.0) and I can get the document pointer in
each of the views. Is there a way for the MainFrame class and/or the
Application class to get the document pointer as well? I need to store
some data in the document in either the Frame class or Application class
that the views will use.

To retrieve all the docs from your MainFrame, you may use this, for example:

CMyApp *myApp =(CMyApp *)AfxGetApp();
POSITION pos = myApp->m_pDocTemplate->GetFirstDocPosition();
CMyDoc *pDoc;

while(pos){
pDoc = (CMyDoc *)myApp->m_pDocTemplate->GetNextDoc(pos);
...
}

To get the active one, use CFrameWnd::GetActiveDocument() (see doc for more infos)

HTH.

Ash to ash and clay to clay, if the enemy doesn't get you, your own folk may.

// I tried this and it seems to work:

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

// 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();
CMyDoc* pDoc = pView->GetDocument();
//
// you'll need to include: mydoc.h and myview.h in your mainframe header.

In MFC, the relation between View and Doc, is control by DocTemplate, if no DocTemplate at APP::InitInstance() , you can not get valide Doc pointer.
You have to direct use DocTemplate var or Doc var of APP.

Thanks to everyone. Program works fine now.

Hi,

I ran into the same problem with you. You said you have worked it out. Could you kindly send me a sample? Millions of thanks!
