Hi all, I need help using the SDK version 2.52.

I’m trying to send a facial template using this piece of code (adapted from the SDK to suit my necessities):

```auto
public int SendPhoto(DevClock connectedClock, AnvizPhoto photo, AnvizUser user)
{
  int ret = 0;
  if ((connectedClock.DevTypeFlag & (int)AnvizLib.MODE_FP_Type.DEV_TYPE_FLAG_FACEPASS_PICTURE) != 0)
  {
    if (photo.DataLength > 0)
    {
      AnvizLib.CCHEX_DEL_PERSON_INFO_STRU Data;

      Data.EmployeeId = new byte[5];
      Conversions.string_to_byte(user.UserID, Data.EmployeeId, 5);
      Data.operation = 11;

      byte[] photoArray = new byte[photo.DataLength];
      Array.Copy(photo.BinaryData, 0, photoArray, 0, photo.DataLength);

      ret = AnvizLib.CChex_UploadFacePictureModule(anviz_handle, connectedClock.DevIdx, ref Data, photo.BinaryData, photo.DataLength);
    }
  }
  return ret;
}

```

This code works fine, but when I get the CChex\_Update message type in return it gives me an error (Result -1).

```auto
case (int)AnvizLib.MsgType.CCHEX_RET_UPLOAD_FACE_PICTURE_MODULE_TYPE:
{
  AnvizLib.CCHEX_UPLOAD_FACE_PICTURE_MODULE result;
  result = (AnvizLib.CCHEX_UPLOAD_FACE_PICTURE_MODULE)Marshal.PtrToStructure(pBuff, typeof(AnvizLib.CCHEX_UPLOAD_FACE_PICTURE_MODULE));
  DevClock clock = GetConnectedClock(dev_idx[0]);

  if (result.Result == 0)
  {
    SWLogger.DebugFmt("Photo succesfully uploaded. Result {0} [User {1} - Device {2} ({3})]",
                      result.Result, Conversions.Employee_array_to_srring(result.EmployeeId),
                      clock.Clock.Name, clock.Clock.Ip);
  }
  else
  {
    SWLogger.DebugFmt("Photo failed to upload. Result {0} [User {1} - Device {2} ({3})]",
                      result.Result, Conversions.Employee_array_to_srring(result.EmployeeId),
                      clock.Clock.Name, clock.Clock.Ip);
  }
}
break;

```

The picture was downloaded using the CChex\_DownloadFacePictureModule SDK method, getting the result from the CChex\_Update with a message type of CCHEX\_RET\_DOWNLOAD\_FACE\_PICTURE\_MODULE\_TYPE and saved into a SQL Server instance using a VarBinary field to store the data from the picture.

Am I doing something wrong?  
I appreciate any help you can provide.  
Thanks in advance.
