用GetSystemMenu试试Top

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

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?

试试这个函数

}
