本文介绍如何利用ActiveX技术在MFC环境中创建一个类似对话框的控件，并将其嵌入到浏览器中显示。具体步骤包括创建MFC ActiveX控件项目、设计对话框资源、添加CDialog派生类及成员函数等。
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;
}
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>
<body>
<OBJECT ID="DialogControl" CLASSID="CLSID:insert here the GUID from ODL file"
HEIGHT=300 WIDTH=300>
</OBJECT>
</body>
</html>
调试
In project setting and debug tab –excutable for debug session,you set default webbrower,program arguments set –blank or your html directory
