How to rename or relabel a Network Drive label

Question

I am mounting a network drive to windows using WNetAddConnection2 which is working fine but while mounting the drive by default it assigns the name as Server IP and FolderName ,

NDSTestFolder on 'NAS server (172.24.17.116)'(R:)

I need to rename the drive label using SetVolumeLabel but this fails for the network drive saying invalid parameter while SetVolumeLabel works fine for the local drives.

Is there a way I can rename or relabel a network drive? So that I can change

NDSTestFolder on 'NAS server (172.24.17.116)'(R:)

to

NDS@MyFolder (R:)

Answer 1

Not sure if there's an API for this but the strings are stored in the registry under:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2

Find the correct subkey by parsing the keys there (it will probably look like "##172.24.17.116#NDSTestFolder" ) and change the _LabelFromReg value to whatever you like...

Answer 2

I tried using vb script for renaming thr drive:

LPCTSTR szCode = "Function RenameDrive(strNewName,strDriveLetter) \r\n\
                     Dim objShell \r\n\
                     Set objShell = CreateObject(\"Shell.Application\") \r\n\
                     'if objShell is Not Nothing Then \r\n\
                     objShell.NameSpace(strDriveLetter).Self.Name = strNewName \r\n\
                     'End if \r\n\
                     End Function";

Translated your script into C++:

#include <shldisp.h>

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);
      VariantClear(&vt);
      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();
   }
}
