What do you mean? Is your application dialog based, sdi or mdi?

You can add one frame on dialog and create view with CFormView
same:
pMainFrame = (CFrameWnd*) RUNTIME_CLASS(CFrameWnd)->CreateObject();

CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(128,
RUNTIME_CLASS(CDocument),
RUNTIME_CLASS(CFrameWnd),
RUNTIME_CLASS(CFormView));

CCreateContext sContext;
sContext.m_pCurrentDoc = (CDocument*) RUNTIME_CLASS(CDocument)->CreateObject();
sContext.m_pCurrentFrame = NULL;
sContext.m_pLastView = NULL;
sContext.m_pNewDocTemplate = pDocTemplate;
sContext.m_pNewViewClass = RUNTIME_CLASS(CFormView);

m_pMainFrame ->Create(strCssEditorClass, _T(""), WS_CHILD, CRect(0,0,1,1), this, NULL, 0, &sContext);
pMainFrame ->MoveWindow(0,0,200,200);
pMainFrame ->ShowWindow(SW_SHOW);
// OnInitDialog()

.: Your success is also mine :.

hi,

i am getting null value when i use the above code please help me out.

//================================================================

CFrameWnd *pMainFrame = (CFrameWnd*)RUNTIME_CLASS(kiranfrm)->CreateObject();
if(pMainFrame->m_hWnd == NULL)
{
//I am getting Null value here so i cant able to create a Handle.
}

//================================================================

Steps what i have done.

1) Create a Dialog and place a Button and in the Click even i pasted what you have mentioned.
2) Create a CForm and create CFormClass,CFormDoc Class,CFrameWnd Class.

//here is the Total Code please see it

CFrameWnd *pMainFrame = (CFrameWnd*)RUNTIME_CLASS(kiranfrm)->CreateObject();
if(pMainFrame->m_hWnd == NULL)
{
MessageBox("hellow");
return ;
}

CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(128,
RUNTIME_CLASS(kirandoc),
RUNTIME_CLASS(kiranfrm),
RUNTIME_CLASS(kiran));

CCreateContext sContext;
sContext.m_pCurrentDoc = (CDocument*) RUNTIME_CLASS(kirandoc)->CreateObjec();
sContext.m_pCurrentFrame = NULL;
sContext.m_pLastView = NULL;
sContext.m_pNewDocTemplate = pDocTemplate;
sContext.m_pNewViewClass = RUNTIME_CLASS(kiran);

pMainFrame ->Create("", _T(""), WS_CHILD, CRect(0,0,1,1), this, NULL, 0, &sContext);
pMainFrame ->MoveWindow(0,0,200,200); //Error
pMainFrame ->ShowWindow(SW_SHOW); //Error

because m_hWnd is NULL.

CString strClass= AfxRegisterWndClass(CS_VREDRAW|CS_HREDRAW, ::LoadCursor(NULL, IDC_ARROW), (HBRUSH)::GetStockObject(WHITE_BRUSH), ::LoadIcon(NULL, IDI_APPLICATION));

pMainFrame ->Create(strClass, _T(""), WS_CHILD, CRect(0,0,1,1), this, NULL, 0, &sContext);

if you want to go from one dialog to CFormView see

CFrameWnd* pFrame = (CFrameWnd*)AfxGetApp()->m_pMainWnd;<br />
CPictureView* pView = (CPictureView *) pFrame->GetActiveView();

and use from pView->variables or functions

DirectShow? You can have a look at the AMCap sample that comes with the SDK. You can just connect up the Capture filter -> Sample Grabber filter -> Null Renderer to get a bitmap from the Sample Grabber. There are various articles on DirectShow on CodeProject, just look them up.

Use CMain* pmain=(CMain*)GetParent();
pmain->GetDlgItemText(IDC_EDIT1,str);
etc.....//Main is the class from where you are calling this second dialog
I haven't tried this code on the machine right now but hope it works and helps you

Somethings seem HARD to do, until we know how to do them.

    Cdlgbox dlg;
