How to write a LPOLESTR to a text file?

I am very new to c++ and need to write a LPOLESTR to a text file.  Is this possible or do I need to convert it to something else?  Also, are there any specific header files I need to accomplish this?  I have already used the funtion StringfromCLSID to convert GUID's to printable strings but apparently they are not writable.  I can't import the fstream class for some reason also so I havn't used that.

This is the code segment -

// Execute the search
    hr = pSearch->ExecuteSearch(    pszSearch,
                                    rgAttributes,
                                    ARRAYSIZE(rgAttributes),
                                    &hSearch);
      cout << "Search Executed: " << hr << endl;
    if(SUCCEEDED(hr))
    {  
        FILE* myOutputFile;
        myOutputFile = fopen("c:\\TestWatch\\ADDeleted.txt", "w");
        // Call IDirectorySearch::GetNextRow() to retrieve the next row of data
        while(S_OK == (hr = pSearch->GetNextRow(hSearch)))
        {
            ADS_SEARCH_COLUMN col;
            UINT i;
           
            // Enumerate the retrieved attributes.
            for(i = 0; i < ARRAYSIZE(rgAttributes); i++)
            {
                hr = pSearch->GetColumn(hSearch, rgAttributes[i], &col);
                if(SUCCEEDED(hr))
                {      
                                                   
          switch(col.dwADsType)
                    {
                        case ADSTYPE_CASE_IGNORE_STRING:
                        case ADSTYPE_DN_STRING:
                        case ADSTYPE_PRINTABLE_STRING:
                        case ADSTYPE_NUMERIC_STRING:
                        case ADSTYPE_OCTET_STRING:
                            wprintf(L"%s: ", rgAttributes[i]);
                            LPOLESTR pStr;
                            for(DWORD x = 0; x < col.dwNumValues; x++)
                            {                                          
                                StringFromCLSID( (REFCLSID)col.pADsValues[x].OctetString.lpValue, &pStr );
                                                      // write to text file hear                                        fput(pStr, myOutputFile);
                                wprintf(L"%s" ,pStr);
                                CoTaskMemFree((LPVOID)pStr );
                                if((x + 1) < col.dwNumValues)
                                {
                                    wprintf(L",");
                                }
                            }
                            wprintf(L"\n");
                            break;
                    }

                    pSearch->FreeColumn(&col);
                }
            }

            wprintf(L"\n");
        }
            fflush(myOutputFile);
            fclose(myOutputFile);
        // Close the search handle to cleanup.
        pSearch->CloseSearchHandle(hSearch);
    }

An LPOLESTR basically is an UNICODE string. So, all you have to do is using the UNICODE file I/O functions, e.g.

        FILE* myOutputFile;
        myOutputFile = _wfopen(L"c:\\TestWatch\\ADDeleted.txt", L"w");


//...

                                StringFromCLSID( (REFCLSID)col.pADsValues[x].OctetString.lpValue, &pStr );
                                             // write to text file hear
                                    fputws(pStr, myOutputFile);

//...

          fflush(myOutputFile);
          fclose(myOutputFile);
