Using CDoc variable in MainFrm

[jw81]

Hi I have trouble using CDoc variable in MainFrm. I have included Cdoc.h in MainFrm but the error of undeclared variable still existed.

CDoc& pDoc = GetDocument();
ASSERT_VALID(pDoc);

This is how I normally getting CDoc variable from CView but it doesnt work in MainFrm. Please advise. THanks.

I think there is a GetActiveDocument(). If not that, then use GetActiveFrame(), from there you get the view of the frame and from that the document of the view. Its a bit long winded. If you vote me down, my score will only get lower

Hi Thanks for the advice. Now, I created a new dialog class and i wanna use CDoc variable. AfxGetMainWnd doesnt work. I have tried GetActiveDocument and GetActiveFrame but it is for MainFrm. THanks.
