Question

I have an MFC view, and I have another project which implements and MFC dialog.
I want to host the dialog in my view.
My view is of class CFormView.

I did it that way in my view code:

m_myDialog->Create(myDialog::IDD, this);

Now, I see my dialog, but I can’t set focus on it and can’t use it.

What do I have to change in order to host my dialog in my view, and be able to use it and set focus to it, just as part of the view?

Thanks

I know this is a few weeks old, but you need to provide more code or a better context of what is taking place.

I had a similar problem to yourself & found this hard to find info on when I first tried this. Following is an abstract of something I’ve used. I’m sure there’s probably a better way to do this, but I find it works the way I want;

        //MyApp.h

        class MyDialogClass;

        class MyApp : public CWinAppEx
        {
        public:
            MyApp();
            virtual BOOL InitInstance();
            //code etc
            MyDialogClass *p_myDlg;
        };


        //MyApp.cpp
        #include "MyApp.h"
        #include "CMyView.h"
        #include "mydialogclass.h"


        BOOL MyApp::InitInstance()
        {
        //code etc

            p_myDlg = CMyView::GetView()->p_myDlg;  

        //can be used here or elsewhere. I have mine linked with a button
            p_myDlg->ShowWindow(true);

        };


        //CMyView.h

        class MyDialogClass;

        class CMyView : public CFormView
        {
         protected: // create from serialization only
            CMyView();
            DECLARE_DYNCREATE(CMyView)

         public:
            enum{ IDD = IDD_CMyView_VIEW };

                static CMyView* GetView();
                MyDialogClass *p_myDlg;
            afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
        };


        //CMyView.cpp
        #include "MyApp.h"
        #include "CMyView.h"
        #include "mydialogclass.h"

        int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct)
        {
            if (CFormView::OnCreate(lpCreateStruct) == -1)
                return -1;

            p_myDlg = new MyDialogClass(this);

            return 0;
        }

        void CMyView::DisplayDialogFoo()
        {

           //can be used here or elsewhere. I have mine linked with a button
           p_myDlg->ShowWindow(true);

        }

        //mydialogclass.h
        class MyDialogClass : public CDialog
        {
            DECLARE_DYNAMIC(MyDialogClass)
         public:
            MyDialogClass(CWnd* pParent /*= NULL*/);
            enum { IDD = IDD_MyDialog_DLG };
        };

        //mydialogclass.cpp
        #include "mydialogclass.h"

        MyDialogClass::MyDialogClass(CWnd* pParent /*=NULL*/)
            : CDialog(MyDialogClass::IDD, pParent)
        {
            Create(IDD, pParent);
        }
