Open Desktop Items

Hi,
I'm making a Desktop kind of program.
It scans the Desktop Folder via:

          if( SHGetDesktopFolder(&pDTF) == NOERROR )
          {
               if( pDTF->EnumObjects(hWnd, SHCONTF_FOLDERS | SHCONTF_NONFOLDERS | SHCONTF_INCLUDEHIDDEN, &pEIL) == NOERROR )
               {
                    while( pEIL->Next(1, &pDTIcon, &uNumIcon) == NOERROR )
                    {
                         if( SHGetFileInfo((LPCTSTR)pDTIcon, 0, &fi, sizeof(fi), SHGFI_DISPLAYNAME | SHGFI_PIDL | SHGFI_ICON | SHGFI_TYPENAME | (bSmall ? SHGFI_SMALLICON : SHGFI_LARGEICON)) )
                         {


It works perfectly

But now my question:
I want to open all of the items in the Desktop Folder (not all at once ofcourse). There are also the items like "My Computer" "Internet Explorer" etc. those are "Sytem Folders" (fi.szTypeName). How can I open/run these system folder types??
The "My Documents" is no problem, I can get the path (SHGetPathFromIDList()) and ShellExecute it, but those other ones??

Can somebody help me?

If the question is too hard for 100 points just let me know!

Hmmmmm... Let me look in my code again...

Sorry, I should have said that from the beginning. My Delphi code looks something like this (I've shorted it a bit):

procedure ExecuteDefaultItem(cm: IContextMenu; parentWnd: dword);
var ici  : TCMInvokeCommandInfo;
    menu : dword;
begin
  menu := CreatePopupMenu;
  try
    zeroMemory(@ici,sizeOf(ici));
    with ici do begin
      cbSize := sizeOf(TCMInvokeCommandInfo);
      fMask  := CMIC_MASK_FLAG_NO_UI;
      hwnd   := parentWnd;
      nShow  := SW_SHOW;
    end;
    cm.QueryContextMenu(menu, 0, 1, $7FFF, CMF_DEFAULTONLY);
    ici.lpVerb := pchar(GetMenuDefaultItem(menu, 0, 0) - 1);
    cm.InvokeCommand(ici);
  finally DestroyMenu(menu) end;
end;

Regards, Madshi.

You'd use 'SHGetSpecialFolderLocation()' together with 'SHGetPathFromIDList()' to open them...

when I do this:

     CHAR     szCommand[MAX_PATH+1];
     LPMALLOC      pMem    = NULL;
     LPITEMIDLIST  pSpecFolder = NULL;

     if( SHGetMalloc(&pMem) == NOERROR )
     {
          SHGetSpecialFolderLocation(hWnd,CSIDL_DRIVES,&pSpecFolder);
          SHGetPathFromIDList(pSpecFolder,szCommand);


     }

szCommand is empty :(

As you enumerate throught the contents of the desktop using the "Next" function, you get PIDLs for the items on the desktop returned in the 2nd argument to "Next".
( or at least the Address of an array of ITEMIDLIST pointers).
These PIDLs can be plugged back into the parent directory (the desktop in this case) using pDTF->BindToObject and...
you end up with an IShellFolder interface for the next level down the Namespace hierarchy. You can then EnumObjects on that interface and so on down until you reach the bottom of the tree.

But you will need patience, close attention to whether you've got an ILD, a PIDL or a PILD*. Oh and you will also need plenty of luck.

Cheers

PS. I think the PIDLS you get from EnumObjects are always relative to their parent in the namespace so use IBindToObject on the parent IShellFolder not the root IShellFolder.

I'm doing it like this:

(1) Call IShellFolder.GetUIObjectOf to get an IContextMenu instance of the context menu of the desktop items.
(2) Call IContextMenu.InvokeCommand to "execute" the item. This should open the item.

It's true, tx, one little question before you get your points :-) Can I just invoke command '0' Or do I have to check wich item of the ContextMenu is "open"
