Getting info from a Document in a dialog?

[D_D]

I have a dialog called from my Document, and it needs to access a CMap declared in the document (Doc/View architecture). Any idea how I can do this, since GetParent only works for window types?

Thanks,
DD

try this:

CYourAppDoc * CYourDialog::GetDocument()
{
POSITION pos = AfxGetApp()->GetFirstDocTemplatePosition();
CDocTemplate * pSingleDocTemplate = AfxGetApp()->GetNextDocTemplate(pos);
pos = pSingleDocTemplate->GetFirstDocPosition();
return (CYourAppDoc*)pSingleDocTemplate->GetNextDoc(pos);
}

then in some func (in same dialog, of course) call

CYourAppDoc* pDoc = GetDocument();
pDoc->SomeFunc(); // for example....

....don't forget to #include doc header....

stay good

If the document calls up the dialog (and it should if the dialog is dealing with document data), you can also have a CDocument member of the dialog which the document sets.

CMyDialog dlg;
dlg.m_pDoc = this;

In OnInitDialog()

ASSERT(m_pDoc != NULL);

Dear sir,
The following code maybe useful to you:
CView* GetActiveView()
{
CFrameWnd* pFrame = (CFrameWnd*) AfxGetApp()->m_pMainWnd;
ASSERT(pFrame->IsKindOf(RUNTIME_CLASS(CFrameWnd)));

CView *pView = pFrame->GetActiveView();
#if _MFC_VER >= 0x0250
if (pView == NULL)
pView = pFrame->GetActiveFrame()->GetActiveView();
#else
if (pFrame->IsKindOf(RUNTIME_CLASS(CMDIFrameWnd)))
{
CWnd* pWnd = ((CMDIFrameWnd*)pFrame)->MDIGetActive();
if (pWnd)
pFrame = (CFrameWnd*) pWnd;
}
pView = pFrame->GetActiveView();
#endif

return pView;
}

CDocument* GetActiveDocument()
{
CFrameWnd * pFrame = (CFrameWnd *)(AfxGetApp()->m_pMainWnd);
if (pFrame->IsKindOf(RUNTIME_CLASS(CMDIFrameWnd)))
{
CMDIChildWnd * pChild =
((CMDIFrameWnd*)(AfxGetApp()->m_pMainWnd))->MDIGetActive();
if ( !pChild )
return NULL;
return pChild->GetActiveDocument();
}
return pFrame->GetActiveDocument();
}
