這裏是封裝到一個類的方法準備到去解決。

bool CBluetooth::ChangeLocalRadioName(LPTSTR newName) 
{ 
    LPTSTR instanceID = GetGenericBluetoothAdapterInstanceID(); 

    if (instanceID == NULL) 
    {  
     //_tprintf(_TEXT("Failed to get Generic Bluetooth Adapter InstanceID\n")); 
     return false; 
    } 
    LPTSTR instanceIDModified = new TCHAR[_tcslen(instanceID)]; 
    _tcscpy(instanceIDModified, instanceID); 
    find_and_replace(instanceIDModified, _TEXT("\\"), _TEXT("#")); 


    HANDLE hDevice; 
    TCHAR fileName[1024] = { 0 }; 
    _tcscpy(fileName, _TEXT("\\\\.\\"));  
    _tcscat(fileName, instanceIDModified); 
    _tcscat(fileName, _TEXT("#{a5dcbf10-6530-11d2-901f-00c04fb951ed}")); 

    hDevice = CreateFile(fileName, GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL); 

    if (hDevice == INVALID_HANDLE_VALUE) 
    { 
     //_tprintf(_TEXT("Failed to open device. Error code: %d\n"), GetLastError());  
     return false; 
    } 

    //Change radio module local name in registry 
    LPTSTR RMLocalName = newName; 
    CHAR bufRMLocalName[256]; 

    HKEY hKey; 
    TCHAR rmLocalNameKey[1024] = { 0 }; 
    LSTATUS ret; 
    _tcscpy(rmLocalNameKey, _TEXT("SYSTEM\\ControlSet001\\Enum\\"));  
    _tcscat(rmLocalNameKey, instanceID); 
    _tcscat(rmLocalNameKey, _TEXT("\\Device Parameters")); 

    ret = RegOpenKeyEx(HKEY_LOCAL_MACHINE, rmLocalNameKey, 
     0L, KEY_SET_VALUE , &hKey); 

    if(ret != ERROR_SUCCESS) 
    { 
     //_tprintf(TEXT("Failed to open registry key. Error code: %d\n"), ret); 
     return false; 
    } 

    ret = RegSetValueEx(hKey, _TEXT("Local Name"), 0, REG_BINARY, 
     (LPBYTE)RMLocalName,strlen(RMLocalName)); 

    if (ret != ERROR_SUCCESS) 
    { 
     //_tprintf(TEXT("Failed to set registry key. Error code: %d\n"), ret); 
     return false; 
    } 

    RegCloseKey(hKey); 

    // This check decides what IO control code to use based on if we're in XP or Vista (and later). 
    OSVERSIONINFO osver; 
    osver.dwOSVersionInfoSize = sizeof(osver); 
    GetVersionEx(&osver); 

    UINT ctlCode = (UINT)(6 > osver.dwMajorVersion ? 0x220fd4 : 0x411008); 
    long reload = 4; // tells the control function to reset or reload or similar... 
    DWORD bytes = 0; // merely a placeholder 

    // Send radio module driver command to update device information 
    if (!DeviceIoControl(hDevice, ctlCode, &reload, 4, NULL, 0, &bytes, NULL)) 
    { 
     //_tprintf(TEXT("Failed to update radio module local name. Error code: %d\n"), GetLastError()); 
     return false; 
    } 



    return true; 

}
