Please Help! ItemIDLists

[Hardeep Singh]

I'm posting a query on ItemIDLists for the third time...
Isn't there anyone who can show me a few lines of code on using an ItemIDList and accessing the folder it represents? The VC++ help on this topic is pretty vague, and I've just been trying to get these things to work but with no success.
I can't even seem to get something as straightforward as the file system directory of the recycle bin using the getpathfromidlist() function... I just can't figure out why that didn't work. So maybe I'm missing something... Please let me know soon.
Thanks.

I am 99% certain, assuming getpathfromidlist() is the same as WIN32's ShGetPathFromIDList(), that this ONLY returns a path from a PIDL if the PIDL represents a path in the normal filing system. The recycle bin is not in the normal filing system, it is a special folder - so you must use the equivalent of ShGetSpecialFolderLocation() to retrieve it. Does this help?

Can you at least tell me how to use the shell interfaces and their functions which will help me access shell objects? If you can I'll be very grateful

Well, I'm afraid I don't know that much myself. All I know is that this snippet:

---
char cBuffer[_MAX_PATH];
CString strDirectory ;

if (SHGetPathFromIDList(lpsList,(LPSTR)cBuffer) )
strDirectory = cBuffer ;
---

will put the path into strDirectory if lpsList (an LPITEMIDLIST, which represents a folder) points to something in the normal file system.

This code snippet will get an LPITEMIDLIST for one of the special folders:

---
CWnd *pWndMain ;
LPITEMIDLIST *plpsList ;

pWndMain = AfxGetMainWnd();
if (pWndMain != NULL)
{
ShGetSpecialFolderLocation(pWndMain-&gt;m_hWnd, CSIDL_BITBUCKET, plpsList);
}
---

The above code gets an identifier of the recycle bin; use one of the other CSIDL_ constants given in the help for the function for the other folders. You would then use the resulting ID for other shell functions. Where a pointer to an ID is required, simply use "plpsList"; where an ID is required itself, use "*plpsList".

ShAddToRecentDocs() adds a file or special item to the Start menu's Documents menu; the first parameter is SHARD_PATH if the second parameter points to a string describing a normal filespec (e.g. "C:\My Work\SomeFile.txt"), or is SHARD_PIDL if the second parameter points to an ID (plpsList from above, for example, to add the recycle bin to the recent docs list - whether this is possible or not, I don't know).

There are many other Sh...() functions, a lot of which I don't understand. I can't really give you any more information than the help file can, but if you want to, write to [email protected] telling me what you want to do and I'll see if I can give you the code to do it; if not, then you will have to resort to this message board again.
