急用 谢谢

用GetSystemMenu试试

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

[随风bj]

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"

[Kaile]

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

CSDN程序员光盘里有现成的源代码

文章题目为：

Associate File Extension with Shell OPEN command and Application
将文件扩展名同命令行和应用程序关联

[dx79]

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?

试试这个函数
