How to get access to CMyView variables from CMainFrame in MFC
-
Hi Everybody I have a SDI project. I have created some dynamics ComboBoxes in my toolbar by ".Create" in my CMainFrame Class. My ComboBoxes are working properly in CMainFrame but I want to set some of my variables in CMyView class by void CMainFrame::OnSelchange_My_Dynamics_Combo_1(). I did my best but I was not successful to send/set data to/at CMyView class. I am beginner in MFC, Please guide me. Best Regards

Have you tried calling
GetActiveView()?"One man's wage rise is another man's price increase." - Harold Wilson

Your
CMyViewobject should be a member of theCMainFrame, so you just need to add apublicmethod toCMyViewthat does what you want.Dear Friend I did it,Because it seemed very easy, but then I get CDocument ERROR! After adding #include "CMyView.h" into CMyMainFrame, I get CDocument ERROR! I searched a lot on the internet, all say use GetActiveView() but it does not work! Best Regards

Yes, dear friend I write the following code inside MyCMainFrame file : MyCView*pView = static_cast (GetActiveWindow()); then when I include MyCView.h file inside MyCMainFrame file to use GetActiveView(), then I get CDocument ERROR!!!

Sorry, we cannot guess what you are doing. You need to show the code that that you are running, and explain exactly what error(s) you see and where it happens.
Dear friend I write the following code inside MyCMainFrame.cpp file : MyCView*pView = static_cast (GetActiveWindow()); pView->m_CMyView_Pulic_Variable; To get access to public variables inside CMyview class. But when I include MyCView.h file inside MyCMainFrame file to use GetActiveView(), then I get CDocument ERROR! In fact, I just want to change a public variable inside CMyView class from MyCMainFrame. How can I get access to CMyView class public variables, from MyCMainFrame? Best Regards

Why are you using
GetActiveWindowrather thanGetActiveView? And what is the exact text of the error you receive and where does it occur?Dear Richard Firstly "HAPPY NEW YEAR" Many thanks for your help, I was engaged with the CMyDoc error, finally I found it, simply it was redefinition of CMyDoc header in 2 different classes that I never guessed such mistake. Best Regards
