Windows上通过程序设置盘符对应的友好名称

　　一个小技巧，与常规SetVolumeLabel不同，是指设置资源管理器中盘符对应的友好名称，如下图红框所示:
　　#include   //CoInitialize(NULL); void RenameDrive(BSTR strNewName, BSTR strDriveLetter) {     IShellDispatch* pShellDispatch = NULL;     HRESULT hr = CoCreateInstance(CLSID_Shell,                                   NULL,                                   CLSCTX_INPROC_SERVER,                                   IID_IShellDispatch,                                   (void**)&pShellDispatch);     if (SUCCEEDED(hr) && pShellDispatch)     {           Folder* pFolder = NULL;           VARIANT vt = {};           VariantInit(&vt);           vt.vt = VT_BSTR;           vt.bstrVal = strDriveLetter;           hr = pShellDispatch->NameSpace(vt, &pFolder);           if (SUCCEEDED(hr) && pFolder)           {             Folder2* pFolder2 = NULL;             hr = pFolder->QueryInterface(IID_Folder2, (void**)&pFolder2);            	if (SUCCEEDED(hr) && pFolder2)             {               FolderItem* pFolderItem = NULL;               hr = pFolder2->get_Self(&pFolderItem);               if (SUCCEEDED(hr) && pFolderItem)               {                 pFolderItem->put_Name(strNewName);                 pFolderItem->Release();               }               pFolder2->Release();             }             pFolder->Release();           }           pShellDispatch->Release();       } }
