    58) 如何给系统菜单添加一个菜单项 

    给系统菜单添加一个菜单项需要进行下述三个步骤: 
    首先,使用Resource Symbols对话(在View菜单中选择Resource Symbols... 
    可以显示该对话)定义菜单项ID,该ID应大于0x0F而小于0xF000; 
    其次,调用CWnd::GetSystemMenu获取系统菜单的指针并调用 
    CWnd:: Appendmenu将菜单项添加到菜单中。下例给系统菜单添加两个新的 
    int CMainFrame:: OnCreate (LPCREATESTRUCT lpCreateStruct) 

    … 

    //Make sure system menu item is in the right range. 
    ASSERT (IDM_MYSYSITEM &0xFFF0)==IDM_MYSYSITEM) 
    ASSERT (IDM-MYSYSITEM<0xF000) 

    //Get pointer to system menu. 
    CMenu* pSysmenu=GetSystemmenu (FALSE) 
    ASSERT_VALID (pSysMenu) 
    //Add a separator and our menu item to system menu. 
    CString StrMenuItem (_T ("New menu item")) 
    pSysMenu->Appendmenu (MF_SEPARATOR) 
    pSysMenu->AppendMenu (MF_STRING, IDM_MYSYSITEM, strMenuitem) 

    … 

    现在,选择系统菜单项时用户应进行检测。使用ClassWizard处理 
    WM_SYSCOMMAND消息并检测用户菜单的nID参数: 
    void CMainFrame:: OnSysCommand (UINT nID,LPARAM lParam) 

    //Determine if our system menu item was selected. 
    if ( (nID & 0xFFF0)==IDM_MYSYSITEM) 

    //TODO-process system menu item 


    else 
    CMDIFrameWnd:: OnSysCommand (nID, lParam) 

    最后,一个设计良好的UI应用程序应当在系统菜单项加亮时在状态条显示 
    一个帮助信息,这可以通过增加一个包含系统菜单基ID的串表的入口来实现。

    楼上二位没有理解我的意思。可能我没有说清楚,我是想要获得每个文件自己的context menu 
    就是资源管理器里右键单击若干对象后弹出的菜单。

    哎呀,在注册表里加入就可以了Top

    5 楼lhxx(随风) 回复于 2001-02-12 16:15:00 得分 0

    具体是在: 
    HKEY_CLASSES_ROOT\Folder\Shell 
    举个例: 
    如果要加入由键运行得程序为TEST.EXE 
    那么先加入一个主键TEST 
    然后在其下加入一主键command ,将其默认的键值设为test.exe的路径就可以了 
    完成后如下: 
    HKEY_CLASSES_ROOT\Folder\Shell\Test\command\"默认 = test.exe"Top

    6 楼Kaile(领头羊) 回复于 2001-02-12 16:23:00 得分 0

    改写注册表,键值如下: 
    HKEY_CLASSES_ROOT\DIRECTORY\SHELL\MENUNAME 
    HKEY_CLASSES_ROOT\DIRECTORY\SHELL\MENUNAME\COMMAND 设置其值 
    HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\DIRECTORY\SHELL 
    HKEY_LOCAL_MACHINE\SOFTWARE\CLASSES\DIRECTORY\SHELL\COMMAND 设置其值

    难道还是没人懂我的意思吗? 
    我不是想要做文件名关联,也不是想要在系统右键菜单里加入菜单项 
    我是想要获取整个右键菜单并显示出来。我对COM不熟悉,根据MSDN上的说明,要获取 
    IContextMenu就必须先实现IShellExtInit,我不知道该怎么做 

    下面是我写的一段code,最后一句错误返回了。.. 

    IShellFolder *rootpsf, *psf; 
    IContextMenu *pcm; 
    IShellExtInit *pse; 
    ITEMIDLIST *pidl; 
    HMENU hMenu; 
    WORD wsz[MAX_PATH]; 

    rootpsf = NULL; 
    psf = NULL; 
    pcm = NULL; 
    pse = NULL; 
    pidl = NULL; 
    hMenu = NULL; 
    memset(wsz, 0, MAX_PATH); 

    hres = SHGetDesktopFolder(&rootpsf); 
    if (!SUCCEEDED(hres)) 
    goto err_handler; 

    if (!MultiByteToWideChar(CP_ACP, 0, "D:\\Temp\\song.htm", -1, wsz, MAX_PATH)) 
    goto err_handler; 

    hres = rootpsf->ParseDisplayName(hWndMain, NULL, (LPOLESTR)wsz, NULL, &pidl, NULL); 
    if (!SUCCEEDED(hres)) 
    goto err_handler; 

    hres = rootpsf->BindToObject(pidl, NULL, IID_IContextMenu, (LPVOID *)&pcm); 
    if (!SUCCEEDED(hres)) 
    goto err_handler; 

    最后一行总是错误,why?
