I wanted to create a control which would behave as a dialog or
formview (you can place controls here). There is a simple way to do it – to take advantage
of ActiveX.
- Create a new MFC ActiveX ControlWizard workspace (no need to special options).
- Insert a new dialog resource named IDC_MYDIALOG (check following: style – child, border
– dialog frame, visible, control, static edge) - Insert a new MFC class named CMyDialog
(base class CDialog) - Add CMyDialog m_MyDialog member to your CDialogCtrl header source
(don’t forget to add #include "MyDialog.h") - Using classwizard add a member function OnCreate (WM_CREATE)
int CDialogCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (COleControl::OnCreate(lpCreateStruct) == -1)
return -1;m_MyDialog.Create(IDD_MYDIALOG, this);
return 0;
}
Modify the member function OnDraw (the dialog’s size depends on the WIDTH and HEIGHT
specified in the HTML file):
void CDialogCtrl::OnDraw(CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
// TODO: Replace the following code with your own drawing code.
// pdc->FillRect(rcBounds, CBrush::FromHandle((HBRUSH)GetStockObject(WHITE_BRUSH)));
// pdc->Ellipse(rcBounds);m_MyDialog.MoveWindow(rcBounds, TRUE);
}
To show the control in your browser use this simple HTML:
<html>
<head>
<title>DialogControl</title>
</head>
<body><center>
<OBJECT ID=“DialogControl” CLASSID=“CLSID:insert here the GUID from ODL file”
HEIGHT=300 WIDTH=300>
</OBJECT>
</center></body>
</html>
