Detect selection of menu commands from "New" popup menu

Detect selection of menu commands from "New" popup menu

Hi,

I create a folder's background context menu using 
IShellFolder::CreateViewObject() and display it using 
TrackPopupMenuEx(). For the commands from the "New" popup menu, I want 
to do some special handling, so I need a way to tell whether the 
selected command is from this popup menu.
The command IDs aren't constant, so I thought about decrementing the 
command ID until I find a command with the verb "NewFolder". Since the 
"New" popup menu doesn't seem to use more than 3 IDs, I could keep the 
performance hit small and stop after 2 decrements.
Then I'd have the first command ID (ID_FIRST) used by the "New" popup 
menu. If the selected command's ID is >= ID_FIRST and <= (ID_FIRST + 2), 
the selected command would be from the "New" popup menu.
This even works on Windows XP (and probably also on 2003/Vista/2008). 
But on Windows 2000, the "NewFolder" command has no command verb. :-(

How else can I check whether the selected command is part of the "New" 
popup menu? I need this functionality in my Explorer replacement app to 
automatically enter label-edit mode for the newly created item.

i can't think of any way you could reliable catch New menu command ids
if you go through the background menu, but if you manually create the
new menu object (D969A300-E7FF-11d0-A93B-00A0C90F2719) then you have
much more control. Sadly this is misbehaving in vista

btw nice to hear you are working on your own explorer replacement app!
After Jim Mustangpeak, now we only need Jim Barry to create his own,
then we'll all have one each :)

Re: Detect selection of menu commands from "New" popup menu

I'm not sure this will work, but it might be worth a try:

If you implement an IShellView interface, you may be able to pass it to the 
context menu using IObjectWithSite, eg:

IShellView* pMyView;
IContextMenu* pMenu;
// ...
IObjectWithSite* pOWS;
if (SUCCEEDED(pMenu->QueryInterface(IID_IObjectWithSite, (void**)&pOWS)))
{
    pOWS->SetSite(pMyView);
    pOWS->Release();
}

Once the context menu has your IShellView, it should call 
IShellView::SelectItem with the SVSIF_EDIT flag set when it wants an item to 
go into rename mode.

At least I believe this is how Explorer does it :)

Cheers,
Jon

Unfortunately, I don't have anywhere near enough spare time for that! --

Maybe this isn't really an issue. I've found a way to identify commands 
from the "New" menu for XP and above (okay, have not yet checked Vista). 
So I could create a new menu object on older systems and use the other 
method on newer systems.
What does my solution for XP and above look like? Well, I take the 
command id and decrease it until the command verb is "NewFolder". If the 
difference between the clicked command id and the id of the "NewFolder" 
command is 2 (or was it 3?) or less, then the command is part of the new 
menu.
I'm not sure this approach is really reliable. While on my XP and 2003 
systems the menu items below the separator all have the same ID, I'm not 
sure this is guaranteed.

Well, actually this code is for a new ActiveX component.
But last year I've also worked on a clone of XP's Explorer that can be 
used on Vista (I will probably switch to Vista soon and the new Explorer 
drives me nuts). I stopped working on this project when I ran into too 
many problems with thumbnails/UAC shield overlays Vista (maybe I'm just 
too much trying to be perfect *g*). Either I'll revive it or I'll start 
using xplorer² when I switch to Vista.

Re: Detect selection of menu commands from "New" popup menu

Hi Jon,

I already had the same idea. It didn't work (none of my IShellView 
methods was ever called). But I didn't call SetSite and maybe this was 
the problem. I'll try again.

Many thanks

I noticed in context this sounds a bit odd. *g* I implemented 
IShellBrowser (QueryActiveShellView) and IShellView and also handled the 
message WM_GETISHELLBROWSER. None of these was ever called.

I've just tried the IObjectWithSite approach. Unfortunately none of my 
IShellView implementations is ever called.

Thanks anyway
Timo
