Thanks for your help.

Today, I re-debug my project and found two problem
1. SHGetPathFromIDList get empty path.
2. SHGetFileInfo don't work for virtual code
I put part of my code below:

while ((pEnumIDList->Next(1, &pID, &nReturned) != S_FALSE)
            && (nReturned == 1))
{
     if(hr=pDesktop->GetDisplayNameOf(pID, SHGDN_INFOLDER, &Sret)

             == NO_ERROR)
           StrRetToString(Sret, name);

     if(hr=pDesktop->GetDisplayNameOf(pID, SHGDN_FORPARSING, &Sret)

             == NO_ERROR)
           StrRetToString(Sret, path);

     CUseShGetFileInfo FileInfo;
     ptrPath = path.GetBuffer(MAX_PATH);
     SHGetPathFromIDList(pID, ptrPath);
     path.ReleaseBuffer();

     SHGetFileInfo(
          (LPCTSTR)path,
          FILE_ATTRIBUTE_NORMAL,
          &sfi,
          sizeof(SHFILEINFO),
          SHGFI_SYSICONINDEX | SHGFI_SMALLICON |SHGFI_USEFILEATTRIBUTES);

}

Just a guess, but for virtual folders, you may have to use PIDLs and the
SHGFI_PIDL flag. I think this approach should work for everything, and if
it does, it will save you all the rigmarole associated with getting the
paths.
