Santosh:

This is actually documented by microsoft - look in the MSDN
Here is a code sniplet :

//pathname = fullpath of the file/folder

LPSHELLFOLDER deskTopFolder;
HRESULT hresult = SHGetDesktopFolder(&deskTopFolder);
if (SUCCEEDED(hresult))
{
OLECHAR olepathname[MAX_PATH];

MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,pathname,-1,olepathname,MAX_PATH);

// Convert the path to an ITEMIDLIST
ULONG chEaten;
ULONG dwAttributes;
LPITEMIDLIST pidl; // this the pidl for the path name

hresult =
deskTopFolder->ParseDisplayName(NULL,NULL,olepathname,&chEaten,&pidl,&dwAttr
ibutes);

// Release desktop
deskTopFolder->Release();
}

If you have access to MSDN, look at the Wicked Code article:

by Miller Freeman, Inc. Volume 12.

Just search for IContextMenu, and Wicked.

Hi Santosh,

When developing an application that interacts with the Windows 95 shell, it
is often necessary to convert an arbitrary path to a file to an ITEMIDLIST.
This can be accomplished using the IShellFolder::ParseDisplayName API.

MORE INFORMATION

Here is an example of how to use the IShellFolder interface to convert the
path to the file README.TXT in the current directory to an ITEMIDLIST. The
example is written in C. If the program is written using C++, accessing
member functions through the lpVtbl variable is unnecessary.

LPITEMIDLIST pidl; LPSHELLFOLDER pDesktopFolder;

char szPath[MAX_PATH];
OLECHAR olePath[MAX_PATH];
ULONG chEaten;
ULONG dwAttributes;
HRESULT hr;

/ // Get the path to the file we need to convert. //
GetCurrentDirectory(MAX_PATH, szPath); lstrcat(szPath, "\\readme.txt");

/ // Get a pointer to the Desktop's IShellFolder interface. // if
(SUCCEEDED(SHGetDesktopFolder(&pDesktopFolder))) {
//
// IShellFolder::ParseDisplayName requires the file name be in Unicode.
//
MultiByteToWideChar(CP_ACP, MB_PRECOMPOSED, szPath, -1,
olePath, MAX_PATH);

//
// Convert the path to an ITEMIDLIST.
//
hr = pDesktopFolder->lpVtbl->ParseDisplayName(pDesktopFolder,
NULL,
NULL,
olePath,
&chEaten,
&pidl,
&dwAttributes);
if (FAILED(hr))
{
// Handle error...
}

//
// pidl now contains a pointer to an ITEMIDLIST for .\readme.txt. This
// ITEMIDLIST needs to be freed using the IMalloc allocator returned
// from SHGetMalloc().
//

...

}

I found the published information (April 1997, Vol. 12, No. 4), yet I
am still unable to put it to any use. I applied the code that was
needed--IShell::ParseDisplayName--but still unsure of its proper use.
Anyone have a simple solution?
