Hi all,

I am trying to get attendance records deleted from a Face Deep 5 device (firmware 03.80.D5-M-ARF-MI, kernel g68b5cdb\_W04, file system 01.80.04).

The problem is that I don’t know if what I’m doing is right or not while sending the CChex\_DeleteRecordInfo call to the FaceDeep5.

I already looked through the SDK manual but it doesn’t show anything related to that.

I am actually trying to delete a number of old records, so I tried this on C#:

```csharp
int delCount = 10;
CCHEX_DEL_RECORD_INFO_STRU delete_record;
if (delCount > 0)
{
    delete_record.del_type = 2;
    delete_record.del_count = Convert.ToUInt32(delCount);
}
else
{
    delete_record.del_type = 0;
    delete_record.del_count = 0;
}
int ret = AnvizLib.CChex_DeleteRecordInfo(_handle, _devIdx.Value, ref delete_record);

```

The returned result does not show any errors, and I also get a positive result from CChex\_Update, but no record is actually being deleted from the FaceDeep 5.

I can still see the attendance records on the device Web UI and also when calling CChex\_DownloadAllRecords / CChex\_TM\_DownloadAllRecords.

Am I missing something here?

I’d greatly appreciate any help in this regard.

Thank you very much.
