C++/MFC Document/View accessing variables from CToolBar to CFormView

Hello, I am pretty new to the Document/View based MFC programs.
I am searching for 2 days now to an answer to my problem.

1 I have a toolbar derived class called CToolBarEditor
2 I have derived one so I could replace one of the buttons with an CEdit
3 CToolBarEditor is a member of the Mainframe
4 My main form is a Document/View derived from CFormView called CPC_applicationView

As the view is not a DIRECT member of the Mainframe I can not acces the data in it through the MainFrame.

I want:
- the event handler of the toolbar buttons in CPC_applicationView (already done)
- from here accesing the MainFrame and so the toolbar (caption of edit box)

OR:
- the event handler of the toolbar buttons in MainFrame (already tried)
- from here I can access the toolbar.
- from here accesing the CPC_applicationView and so the members/varibales within.

Concluded: I want bidirection communication between CToolBarEditor and CPC_applicationView

GetParent() does not work because I used DERIVED classes and not the base ones.
also (CMainFrame*)GetParent()->... does not work because of design time.

Please help, even the sample of MFC: document/view doesn't give the solution....

Thank you for your reply.
How does it come that I couldn't find a solution like this on internet?
Or why does the example project not have this?
Anyway, Now I know how to do it, thank you, it worked.

Solution 1

1) make your CXXXtoolbar member a public member in mainfrm.h
2) include mainfrm.h in your view class cpp
3) use code like this below to access your toolbar:
CMainFrame *pFrame = (CMainFrame *)GetApp()->m_pMainWnd;
if (pFrame)
pFrame->m_wndToolBar.DoSomeFunction();
