如何区分由IShellFolder的EnumObjects返回的项目

问题描述

我正在尝试使用Shell将计算机放入我的工作组中

I am trying to get the computers in my workgroup using Shell

HRESULT hr = S_OK;
ULONG celtFetched;
LPITEMIDLIST pidlItems = NULL;
LPITEMIDLIST netItemIdLst = NULL;
IShellFolder* pFolder = NULL;
IEnumIDList* pEnumIds = NULL;
IShellFolder* pDesktopFolder = NULL;
LPITEMIDLIST full_pid;

hr = SHGetMalloc(&pMalloc);
hr = SHGetDesktopFolder(&pDesktopFolder);
hr = SHGetSpecialFolderLocation(NULL, CSIDL_COMPUTERSNEARME, &netItemIdLst);
hr = pDesktopFolder->BindToObject(netItemIdLst, NULL, 
                                  IID_IShellFolder, (void **)&pFolder);

if(SUCCEEDED(hr))
{
  hr = pFolder->EnumObjects(NULL, SHCONTF_NONFOLDERS, &pEnumIds);

  if(SUCCEEDED(hr))
  {
    STRRET strDisplayName;
    while((hr = pEnumIds->Next(1, &pidlItems, &celtFetched)) == S_OK && celtFetched > 0)
    {
      hr = pFolder->GetDisplayNameOf(pidlItems, SHGDN_NORMAL, &strDisplayName);
      if(SUCCEEDED(hr))
      {
        wprintf(L"%s\n", strDisplayName.pOleStr);
      }
    }
  }
}

但是，这将返回计算机，媒体设备和流设备(它的名称是?).就像说，在我的工作组上有一台名为OSOFEM的计算机... STRRET::pOleStr返回字符串OSOFEM(这是计算机)，OSOFEM(我认为是流设备)和OSOFEM:[email protected]:(这是Windows Media Player) ).

我的问题是如何区分哪台计算机?当然，不能使用名称，因为将始终返回两个完全相同的名称...

But this returns the Computers, Media Devices, and Streaming Devices (is that it name?). Like say, a computer is called OSOFEM on my workgroup... STRRET::pOleStr returns strings OSOFEM (which is the computer), OSOFEM (I think streaming device), and OSOFEM:[email protected]: (which is the Windows Media Player).

My question is how can I distinguish which is the Computer? Of course, there names can''t be used because two exactly the same name will always be returned...
