vs2008中，在OCX控件中应用doc/view基本步骤

1、利用向导创建一个MFC ActiveX Control控件CMyOCX；
2、在工程中加入ActivDoc头文件和执行文件；
class CActiveXDocTemplate : public CSingleDocTemplate
{
    enum { IDR_NOTUSED = 0x7FFF };

    CWnd* m_pParentWnd;
    CFrameWnd* m_pFrameWnd;
    CString m_docFile;
 CView*  m_pView;

public:
    CActiveXDocTemplate(CRuntimeClass* pDocClass,
        CRuntimeClass* pFrameClass, CRuntimeClass* pViewClass);

    CFrameWnd* CreateDocViewFrame(CWnd* pParentWnd);
    void SaveDocumentFile();

    virtual CFrameWnd* CreateNewFrame(CDocument* pDoc,
        CFrameWnd* pOther);
    virtual CDocument* OpenDocumentFile(
        LPCTSTR lpszPathName, BOOL bVerifyExists = TRUE);
};

3、在CMyOCX头文件中包含#include "ActivDoc.h";
4、将CMyOCX头文件和执行文件中的COleControl全部用CActiveXDocControl替换；
5、添加CMyView、CMyDocument、CMyFrame三个类，它们分别继承于CView、CDocument、CFrameWnd，在它们的头文件中分别将它们
的构造函数和析构函数有protected该成public；
6、在CMyOCX执行文件中包含#include "MyDocument.h"  #include "MyView.h"   #include "MyFrame.h"；
7、在CMyOCX执行文件中的构造函数中添加语句：
 AddDocTemplate(new CActiveXDocTemplate(
  RUNTIME_CLASS(CMyDocument),
  RUNTIME_CLASS(CMyFrame),
  RUNTIME_CLASS(CMyView)));
基本模型形成，然后就可以按照自己的需要向里面添加东西了。
