Biometrics Fingerprint is giving somebody else's information

Question

I have this Biometrics, but it gives me the completely wrong output - the different userid and the verify date at year 2132.

What can be causing such wrong information? I couldn't find any similar problem on Internet. Does anyone else have encountered the same problem like mine?

            if (axCZKEM1.ReadGeneralLogData(GetMachineNumber()))
        {
            while (axCZKEM1.SSR_GetGeneralLogData(GetMachineNumber(), out sdwEnrollNumber, out idwVerifyMode,
                        out idwInOutMode, out idwYear, out idwMonth, out idwDay, out idwHour, out idwMinute, out idwSecond, ref idwWorkcode))//get records from the memory
            {

                dr["User ID"] = sdwEnrollNumber;
                dr["Verify Date"] = idwYear + "-" + idwMonth + "-" + idwDay + " " + idwHour + ":" + idwMinute + ":" + idwSecond;

                dt_log.Rows.Add(dr);
            }
            ret = 1;
        }
        else
        {
            axCZKEM1.GetLastError(ref idwErrorCode);
            ret = idwErrorCode;

            if (idwErrorCode != 0)
            {
                lblOutputInfo.Items.Add("*Read attlog failed,ErrorCode: " + idwErrorCode.ToString());

Answer 1

The date and time at machine must be wrong.

Answer 2

That is not how you should construct DateTime objects. Try using this constructor to construct the DateTime object and then calling ToString with your desired format. If that fails then you can rule out that :

newitem.SubItems.Add(New DateTime(idwYear, idwMonth, idwDay, idwHour, idwMinute, idwSecond).ToString("yyyy-MM-dd hh:mm:ss"))

I would also suggest setting up a breakpoint when constructing the DateTime object and inspect the values of idwYear/Month/etc. to make sure that the referenced variables have the expected values.

I double-checked the documentation for this method and it looks like the signature is correct. I would also recommend checking that your variables are declared as Integer variables (just to make certain).
