问题
I have a table named Attendancelogs where I am saving the records that I fetch from a biometric device, the table structure is;
LogType defines the type of log i.e. Biometric/Manual
CheckType defines the type of entry i.e. I or O
VerifyMode defines the type of punch i.e. Fingerprint/Password
isIgnore is used to exclude an entry from the logs.
Now, what I am trying to do is to write a function called sortFunc(); that will process on the already stored records in the Attendancelogs table. what this is suppose to do is;
Mark the checkType of each employee as
Ifor the first entry, thenOfor their second entry of the date and so on.If an employee has a last
Iat the end of the day, meaning no check out, then the next day's first punch of that employee (with in 12 AM - 7 AM) is considered check out for the previous day (marking as a nighter case for that employee) the rest entries are considered as sequentialIandO.any multiple entries within 10 seconds (or defined time) is ignored and marked
CheckTypeas "Auto Ignored for x seconds"If an employee is not allowed to use Card/Password then his CheckTypes are marked as
Card not allowedorPassword not allowed
Here is the function that I wrote;
public static bool inn = true;
public void sortLogs(int machineNum)
{
DateTime prevDate = DateTime.MinValue;
DateTime currentDate = DateTime.MinValue;
DateTime prevDateTime = DateTime.MinValue;
DateTime currentDateTime = DateTime.MinValue;

var time = DateTime.ParseExact("00:00:00", "HH:mm:ss", null).ToString("hh:mm:ss tt", CultureInfo.GetCultureInfo("en-US"));
lowerBound = Convert.ToDateTime(time).TimeOfDay;
var time2 = DateTime.ParseExact("07:00:00", "HH:mm:ss", null).ToString("hh:mm:ss tt", CultureInfo.GetCultureInfo("en-US"));
upperBound = Convert.ToDateTime(time2).TimeOfDay;
upperBound = new TimeSpan(7, 0, 0);

This did run but it messes up the "12 AM to 7 AM" checks and the password checks, i.e. not the accurate results.
As one of the example seen ^ consecutive O should not be there. I have been going crazy over this!
