Proper explorer context menu
I am not writing a shell extension, rather a separate program that
querys for the explorer context menu. I am able to get the shell
folder of the directory I want ot query. I use an IShellFolder to
represent the folder. When I use it to get the desktop, I have the
option of getting the IShellFolder of C:\Documents And Settings
\Mastadex\Desktop or the Virtual folder that represents the desktop.
Both of these menus are completely different. One has a "New" submenu
on it and the other doesn't. The second menu has a properties menu
item that launches the display settings, the first one doesn't.
Is there an easy way of merging the two menus so that I can get both
"New" and the properties menu item that launches the Display Settings.
Here is how I am getting at the menu as if I was trying to get :
Code Snippet
HMENU getMenu(IShellFolder *sh)
{
LPCONTEXTMENU icm1 = NULL, contextMenu = NULL;
HMENU menu = NULL;
shellFolder->CreateViewObject(NULL, IID_IContextMenu,(void**) &icm1);
if (icm1)
{
icm1->QueryInterface(IID_IContextMenu3, contextMenu);
contextMenu->QueryContextMenu(menu, 0, 1, 10000, CMF_NORMAL |
CMF_EXTENDEDVERBS | CMF_EXPLORE);
return menu;
}
return NULL;
}
Basically, the above approach gives me a menu that has the "New"
submenu in it. If I hange the CreateViewObject() function call into
the bottom example, it will NOT give me the "New" submenu, rather
everything else (Paste, Paste Shotcut, Properties that launch the
display settings) that I would assume you would get as if right
clicked on the desktop.
Code Snippet
HMENU getMenu(IShellFolder *sh, LPITEMIDLIST *pidlArray, int numPidls)
{
LPCONTEXTMENU icm1 = NULL, contextMenu = NULL;
HMENU menu = NULL;
shellFolder->GetUIObjectOf(NULL, numItems, (LPCITEMIDLIST *)
pidlArray, IID_IContextMenu, NULL,(void**) &icm1);
if (icm1)
{
icm1->QueryInterface(IID_IContextMenu3, ppContextMenu);
contextMenu->QueryContextMenu(menu, 0, 1, 10000, CMF_NORMAL |
CMF_EXTENDEDVERBS | CMF_EXPLORE);
return menu
}
}
Is there a way to merge the two LPCONTEXTMENU structures so that I can
get all the options form both menus in one menu. I tried manually
moving each item in the HMENU structures into one HMENU, but the
funcitonallity of the menu (when invoked) did not do anything.
I am basing my menu off of this example:

Re: Proper explorer context menu
Hmmm, I don't understand. You are using Explorer interfaces to get the same
menu as Explorer. But yet you don't want the menu for the Desktop virtual
folder nor for a file system folder? I don't think you want to try to merge
menus that are intended to be separate. And what are you going to do with
this menu?

The reason I dont want either menu is because neither have the full
functionality I am looking for. Hence I am trying to merge it. I am
curently useing the menu for the folder because it has the New
submenu. But it doesnt have Paste, or the properties the launches
display properties. I can modify each menu separately, but I dont have
the invoke command for those menu items that I manually add. If it is
not possible to merge the menus, is it possible to invoke some
function that would emulate the "New" submenu? I knwo the values for
each entry are somewhere in the registry.

Raymond Chen wrote a series of articles about hosting context menus, including how to create composite menus:
http://blogs.msdn.com/oldnewthing/archive/2004/10/06/238630.aspx
http://blogs.msdn.com/oldnewthing/archive/2004/10/07/239197.aspx
The "New" menu is available separately:
http://msdn2.microsoft.com/en-us/library/bb774110.aspx
By the way, the desktop background menu is a composite menu containing the DefView's background menu ("Arrange Icons By", "Refresh", "Paste", and "Paste Shortcut") and the desktop folder's menu ("New" and "Properties").
Note that Vista includes a "New -> Folder" item on the context menu for filesystem folders, but only when it is displayed in the navigation pane.

Thanks for the insight Jim,
What I have currently is just the New submenu showing up. I have two
LPCONTEXTMENU variables, one that shows up the new submenu, and the
other shows the regular desktop menu (minus the new submenu). I am
using the following code to get the new submenu:
CoCreateInstance(CLSID_NewMenu, NULL, CLSCTX_ALL, IID_IShellExtInit,
(void **) &psfShellExt);
psfShellExt->Initialize((LPCITEMIDLIST) psfFolder, NULL, NULL);
psfShellExt->QueryInterface(IID_IContextMenu3, (void **) &lpcm);
How would I go about putting them together into something that
resembles a full context menu? Also, how would rendering be handled
since I am calling IContextMenu::HandleMenuMsg() for just one of the
items.
Thanks for the help so far :)
