Accessing MFC MDI View Class data members from a different MFC MDI view class ?

I have data members i.e, int, CString etc. in my MFC MDI View class,
That I need to access from a different view class
e.g.

Code:

---

class CMFCApplication1View : public CView
{
Public:
  CString myString;
  int a;

etc...
...
};

I need to access the above variables from a different MDI view, etc...
e.g.
class CPropertiesWnd : public CDockablePane
{
...
};

---

This is a properties window, I know how to display variables.
But I do not know how to access these variables from a different class

I cant show the variables that change in the View because I don't know how to access them.

How do I do that ?

Please help,
Thank you.

Do this...

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.
yourMDIView *pView = (yourMDIView*)pChild->GetActiveView();

Now use this to access any member in scope of yourMDIView class...
pView->a = 1;

That how to do it.

NO...

This will not work, you cannot include the view's header file in the PropertiesWnd.cpp or .h file.
Therefore this code will not compile.

Also, This forum area seems dead

MFC is not very popular now (or when it was at it's peak) and so not many people are left that coded in MFC.

I have not coded MDI MFC for at least a decade and have forgotten how to do this....

You say you can not add the required header, have you tried a forward declaration?

Have you tried passing the data into the Property page using the CREATESTRUCT?

Have you tried a global pointer to the view and get/set member functions?
