Im using MFC GridControl 2.7 taken from code proejct in my application.In my grid control, im making second column as check box column. The default state of check box should be true. Later, user can uncheck the checkbox and depends on the state, furthur functinoality wil go. Here i dont know how to set checkbox as checked in default.

m_ctLstCtrl.Create(listRect, this, IDC_TRENDLISTCTRL);

	// fill it up with stuff
	m\_ctLstCtrl.SetEditable(TRUE);
	

	try {
		m\_ctLstCtrl.SetRowCount(9);
		m\_ctLstCtrl.SetColumnCount(15);
		m\_ctLstCtrl.SetFixedRowCount(1);
		m\_ctLstCtrl.SetFixedColumnCount(1);
		
	}
	catch (CMemoryException\* e)
	{
		e->ReportError();
		e->Delete();
		return -1;
	}

for (int row = 0; row < m_ctLstCtrl.GetRowCount()-1; row++)
{
m_ctLstCtrl.SetCellType(row+1,1,RUNTIME_CLASS(CGridCellCheck));
// m_ctLstCtrl.SetItemState(row+1,1, m_ctLstCtrl.GetItemState(row+1,1) | GVIS_SELECTED); //if i do this, blue colr selection is appearing but not check mark

I have included CLIstCtrl in VIe wcalss in OnCreate(). I added headers details in OnCreate(). I want to add check box in Second column on control. If i add extended style LVS_CHECKBOXES, it adds checkbox to first column. But i want that for second column, how can i do that?

m_ctLstCtrl.Create(WS_CHILD | WS_VISIBLE | LVS_REPORT ,listRect, this, IDC_TRENDLISTCTRL);

m\_ctLstCtrl.SetExtendedStyle(m\_ctLstCtrl.GetExtendedStyle() | LVS\_EX\_GRIDLINES|	 LVS\_EX\_FULLROWSELECT| 	LVS\_EX\_ONECLICKACTIVATE );

	
m\_ctLstCtrl.InsertColumn(0,\_T(""),LVCFMT\_RIGHT,20);
m\_ctLstCtrl.InsertColumn(1,\_T("Visible"),LVCFMT\_LEFT,50);  //checkbox under this header
m\_ctLstCtrl.InsertColumn(2,\_T("Status"),LVCFMT\_LEFT,50);
m\_ctLstCtrl.InsertColumn(3,\_T("Trace color"),LVCFMT\_LEFT,50);
m\_ctLstCtrl.InsertColumn(4,\_T("Object"),LVCFMT\_RIGHT,100);
    m\_ctLstCtrl.InsertColumn(5,\_T("Object"),LVCFMT\_RIGHT,100);
m\_ctLstCtrl.InsertColumn(6,\_T("Object Desc"),LVCFMT\_RIGHT,100);

In OnTimer() im adding data to this Listctrl as

TagListctrl.SetRedraw( FALSE );
TagListctrl.DeleteItem(iTagPos);
index = TagListctrl.InsertItem(iTagPos,indexno);
//for 'Status' and 'Tracecolor'- fil color using OnCUstonDrawList()
TagListctrl.SetItemText(iTagPos,4,"Object");
TagListctrl.SetItemText(iTagPos,5,sName);
TagListctrl.SetItemText(iTagPos,6,sDesc);
TagListctrl.SetRedraw( TRUE );

If i use

class CSplitFrame : public CframeWnd

Here, I call the TrendView using following fucntion in mainfrm.cpp,

void CMainFrame::OnTrendview()
{

if( pTrendDisplayFrame == NULL )
{
	iWindowNumber = 4;
	CDocTemplate \*pTemplate = theApp.pTrendViewTemplate;
	CCS3OprDoc\* pDoc = new CCS3OprDoc;
	pTrendDisplayFrame = (CMDIChildWnd \*)pTemplate->CreateNewFrame( pDoc ,NULL );
	if( pTrendDisplayFrame == NULL )
	{
		MessageBox( "Unable to Create Trend Display" );
		return;
	}
	pTemplate->InitialUpdateFrame( pTrendDisplayFrame,NULL );
}
else
	MDIActivate( pTrendDisplayFrame );

}

Here it comes messagebox “Unable to create trend display” becoz pTrendDisplayFrmae is null. Frame is not created in CreateNewFrame(),it return null from this function call from doctempl.cpp

// create new from resource
if (!pFrame->LoadFrame(m_nIDResource,
WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, // default frame styles
NULL, &context))
{
TRACE(traceAppMsg, 0, "Warning: CDocTemplate couldn't create a frame.\n");
// frame will be deleted in PostNcDestroy cleanup
return NULL;
}

When I use CsplitFrame as MDIChilWNd

class CSplitFrame : public CMDIChildWnd

IT shows assertion error in winmdi.cpp

// walk up two parents for MDIFrame that owns MDIChild (skip MDIClient)
CMDIFrameWnd* CMDIChildWnd::GetMDIFrame()
{
ASSERT_KINDOF(CMDIChildWnd, this);
ASSERT(m_hWnd != NULL);
HWND hWndMDIClient = ::GetParent(m_hWnd);
ASSERT(hWndMDIClient != NULL);

CMDIFrameWnd\* pMDIFrame;
pMDIFrame = (CMDIFrameWnd\*)CWnd::FromHandle(::GetParent(hWndMDIClient));
ASSERT(pMDIFrame != NULL);
ASSERT\_KINDOF(CMDIFrameWnd, pMDIFrame); //Assertion error occurred here
ASSERT(pMDIFrame->m\_hWndMDIClient == hWndMDIClient);
ASSERT\_VALID(pMDIFrame);
return pMDIFrame;

}

My TrendView base class is

class CTrendView : public CView

TrendListView base class is also CView

class CTrendListView : public CView

Im invoking this TrendListView as follow

void CMainFrame::OnTrendListView()
{
// TODO: Add your command handler code here
iGraphView = 0; //Code added by Mohan //Graph view inactive
if( pTrendListDisplayFrame == NULL )
{
iWindowNumber = 11;
CDocTemplate *pTemplate = theApp.pTrendListViewTemplate;
CCS3OprDoc* pDoc = new CCS3OprDoc;
pTrendListDisplayFrame = (CMDIChildWnd *)pTemplate->CreateNew

I saw that one show CFrameWnd. My window is CMDIChildWnd. So i didnt try first. I tried now. i create CSPlitFrame as CFrameWnd and i coded like below. But when i want my particular window , it shows error on calling that view in Mainframe.cpp.

I have MDI MFC application. For a particular child window, i want to split in to two. Already i have toolbar for topview by using OnCreate() in ChildFrame.cpp. I want to add toolbar for bottom view also. ChildFrame OnCreateClient() code:

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
// TODO: Add your specialized code here and/or call the base class

if(iWindowNumber == 4)
{

CRect cr; 
GetClientRect( &cr);

if (!m\_wndSplitter.CreateStatic(this, 2, 1))
	return FALSE;

if(!m\_wndSplitter.CreateView(0,0, RUNTIME\_CLASS(CTrendView),CSize(cr.Width(), cr.Height()-200),pContext)||		
	!m\_wndSplitter.CreateView(1,0, RUNTIME\_CLASS(CTrendListView),CSize(cr.Width(), cr.Height()-550),pContext))
{
	m\_wndSplitter.DestroyWindow();
	return FALSE;
}
//m\_wndSplitter.SetActivePane(1, 0);
return TRUE;

}
return CMDIChildWnd::OnCreateClient(lpcs, pContext);
}

In OnCreate(), im loading toolbar, but it adds only for TopView. I want to add different toolbar for bootmView. Can we add toolbar using CView::OnCreate()? i tried this but it is not happening. Otherwise i have to create 3 splitter window, middle winodw will have toolbar buttons that can be added using CMiddleView::OnCreate(). How can i get that?

I coded like this for my application.

CString bmpFilePath;
HBITMAP hBmp;
hBmp = (HBITMAP)::LoadImage(NULL,bmpFilePath,IMAGE_BITMAP,0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
CBitmap bmp;
bmp.Attach(hBmp);
CDC dcImage;
if(!dcImage.CreateCompatibleDC(pDC))
return;
BITMAP bm;
CBitmap* pOldBitmap;
bmp.GetBitmap(&bm);
pOldBitmap = dcImage.SelectObject(&bmp);
pDC->BitBlt(350,100, bm.bmWidth, bm.bmHeight, &dcImage, 0, 0, SRCCOPY);

Hi, I want 3 split windows in my application,in that left for Tree control and Right window act as a main window and bottom window have list control to show some log of my application. For that i made this code.. in Mainframe.cpp(), in OnCreateClient()

if(!m_SplitterWnd.CreateStatic(this, 2, 1))
return FALSE;

CRect rect;     
GetClientRect(&rect); 

if(!m\_SplitterWnd.CreateView(1, 0, RUNTIME\_CLASS(CBottomView), CSize(rect.Width(), 50),  pContext))        
	return FALSE;       

m\_SplitterWnd.SetRowInfo(0, 800, 50);
m\_SplitterWnd.SetRowInfo(1, 330, 50);

if (!m\_SplitterWnd1.CreateStatic(&m\_SplitterWnd, 1, 2, WS\_CHILD | WS\_VISIBLE | WS\_BORDER |AFX\_IDW\_PANE\_FIRST, m\_SplitterWnd.IdFromRowCol(0,0)))     
 	return FALSE;     
       // first pane     

if(!m\_SplitterWnd1.CreateView(0, 0,  RUNTIME\_CLASS(CTreeMenuView), CSize(rect.Width()/5,rect.Height()-50), pContext))	          
	return FALSE;      
       //Second pane     

if(!m\_SplitterWnd1.CreateView(0, 1, RUNTIME\_CLASS(CMainWindowView), CSize(rect.Width()-rect.Width()/5,rect.Height()-50), pContext))     
	return FALSE;  

	 	int nWidth=rect.Width();
m\_SplitterWnd1.SetColumnInfo(0, nWidth\*0.25, 50);
m\_SplitterWnd1.SetColumnInfo(1, nWidth\*0.75, 50);


return CMDIFrameWnd::OnCreateClient(lpcs, pContext);

And i have to attach all my child window in right side window( CMainWindowView).. In my app class,

pDocTemplate = new CMultiDocTemplate(IDR_MAINFRAME,
RUNTIME_CLASS(CABBHarmonyDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CMainWindowView));
if (!pDocTemplate)
return FALSE;
AddDocTemplate(pDocTemplate);

pGraphViewTemplate = new CMultiDocTemplate(
	IDR\_MAINFRAME,
	RUNTIME\_CLASS(CABBHarmonyDoc),
	RUNTIME\_CLASS(CChildFrame), 
	RUNTIME\_CLASS(CGraphview));
AddDocTemplate(pGraphViewTemplate);

So when i press F5,this GraphView should display in MainwindowView. But it does not appear.Whats the mistake i did? Pls help me.. in Mianframe.cpp

void CMainFrame::OnGraphview()
{

if( pGraphDisplayFrame == NULL )
{		
	CDocTemplate \*pTemplate = theApp.pGraphViewTemplate;
	CABBHarmonyDoc\* pDoc = new CABBHarmonyDoc;
	pGraphDisplayFrame = (CMDIChildWnd \*)pTemplate->CreateNewFrame( pDoc ,NULL );
	if( pGraphDisplayFrame == NULL )
	{
		AfxMessageBox( "Unable to Create Graph Display" );
		return;
	}
	pTemplate->InitialUpdateFrame( pGraphDisplayFrame,NULL );
}
else
	MDIActivate( pGraphDisplayF

In MDI application we cannot move single window to another monitor. I think if you create view using SDI method,then you can move that particular view to next monitor.
