insert ActiveX into MFC without resource file
in [MFC]
|
From: ccwork on 21 Mar 2005 21:47 Hi, I try to insert ActiveX to my program as following: class MyWnd:public CFrameWnd { public: MyWnd() { CString strControlProgid; strControlProgid="mscal.calendar.7"; m_Control.DestroyWindow(); RECT rc; ::GetClientRect(m_hWnd,&rc); BOOL bStat=FALSE; bStat=m_Control.CreateControl(strControlProgid, "", WS_VISIBLE, rc, this, 5000, NULL, FALSE, NULL); if (bStat == FALSE) { ::MessageBox (m_hWnd,"Error!!","Could not place control",MB_OK); } } private: CWnd m_Control; } class MyApp:public CWinApp { MyWnd *wnd; public: BOOL InitInstance() { AfxEnableControlContainer(); wnd=new MyWnd(); } } The error prompt "Error!! Could not place control" always appear. Anyone know what the problem?
From: Ajay Kalra on 21 Mar 2005 22:05 Unless you are doing it somewhere else, you have not created the window represented by MyWnd *wnd. You have created an object on the heap but not yet called wnd->Create or CreateEx etc. -- Ajay Kalra [MVP - VC++] ajaykalra(a)yahoo.com "ccwork" <ccwork(a)discussions.microsoft.com> wrote in message news:7F11C3BC-5063-4246-8C82-DFB5788C07B7(a)microsoft.com... > Hi, > I try to insert ActiveX to my program as following: > > class MyWnd:public CFrameWnd > { > public: > MyWnd() > { > CString strControlProgid; > strControlProgid="mscal.calendar.7"; > m_Control.DestroyWindow(); > RECT rc; > ::GetClientRect(m_hWnd,&rc); > BOOL bStat=FALSE; > bStat=m_Control.CreateControl(strControlProgid, "", WS_VISIBLE, > rc, > this, 5000, NULL, FALSE, NULL); > if (bStat == FALSE) > { > ::MessageBox (m_hWnd,"Error!!","Could not place > control",MB_OK); > } > } > private: > CWnd m_Control; > } > class MyApp:public CWinApp > { > MyWnd *wnd; > public: > BOOL InitInstance() > { > AfxEnableControlContainer(); > wnd=new MyWnd(); > } > } > > The error prompt "Error!!

From: ccwork on 21 Mar 2005 22:21 Sorry. Actually the code is: class MyWnd:public CFrameWnd { public: MyWnd() { Create(NULL,"MFC Tutorial Part 1 CoderSource Window"); CString strControlProgid; strControlProgid="mscal.calendar.7"; m_Control.DestroyWindow(); RECT rc; ::GetClientRect(m_hWnd,&rc); BOOL bStat=FALSE; bStat=m_Control.CreateControl(strControlProgid, "", WS_VISIBLE, rc, this, 5000, NULL, FALSE, NULL); if (bStat == FALSE) { ::MessageBox (m_hWnd,"Error!!","Could not place control",MB_OK); } } private: CWnd m_Control; } "ccwork" wrote: > "Ajay Kalra" wrote: > > > Unless you are doing it somewhere else, you have not created the window > > represented by MyWnd *wnd.

You are creating the window object by calling new MyWnd, but the window has not been created yet. You need to call MyWnd->Create somewhere. IOW, MyWnd->m_hWnd is NULL at the time when you are creating the control. -- Ajay Kalra [MVP - VC++] ajaykalra(a)yahoo.com "ccwork" <ccwork(a)discussions.microsoft.com> wrote in message news:2E66B713-7683-422B-9B81-D7C538327EEB(a)microsoft.com... > "Ajay Kalra" wrote: > > > Unless you are doing it somewhere else, you have not created the window > > represented by MyWnd *wnd.
