Re: reading text file and calculating the working hours for each employee

hi there,
i made this

<pre>
string[] allLines = System.IO.File.ReadAllLines(@"C:\new.txt");

foreach (string eachRow in allLines)

{

try

{

string[] rowaArray = eachRow.Split(',');

string enrollID = rowaArray[1];

DateTime date1 = DateTime.Now;

DateTime date2 = Convert.ToDateTime(rowaArray[3] + " " + rowaArray[5]);

TimeSpan dtDiff = date1 - date2;

listBox1.Items.Add(dtDiff.Days + " Days " + dtDiff.Hours + " Hours " + dtDiff.Seconds + " Seconds ");

}

catch

(IndexOutOfRangeException ex)

{ }

}
</pre>
i got this output
28 Days 9 Hours 13 Seconds
28 Days 9 Hours 8 Seconds
27 Days 23 Hours 4 Seconds
27 Days 23 Hours 59 Seconds
27 Days 23 Hours 12 Seconds
27 Days 23 Hours 4 Seconds
27 Days 18 Hours 21 Seconds
27 Days 16 Hours 24 Seconds
27 Days 16 Hours 7 Seconds
27 Days 16 Hours 32 Seconds
27 Days 16 Hours 20 Seconds
27 Days 16 Hours 10 Seconds
27 Days 15 Hours 49 Seconds
27 Days 15 Hours 33 Seconds
27 Days 11 Hours 33 Seconds
27 Days 9 Hours 33 Seconds
27 Days 9 Hours 22 Seconds
26 Days 23 Hours 20 Seconds
26 Days 23 Hours 14 Seconds
26 Days 23 Hours 8 Seconds
26 Days 23 Hours 27 Seconds

is this correct? as i feel it's alphabetical.
i want to also ask.if i made a combobox with all employees numbers(enroll no).what event i should use inorder when i select the enroll no.the required number of hours is displayed.

Re: reading text file and calculating the working hours for each employee

It's not alphabetical, it is in order of the lines in your file.
I suspect that what you now need to do is tie your enrol no to "check in" and "check out" from your file, and collect the data for display. That bit is over to you, as I do not have the time to do all your homework for you!
The event you are looking for is (predictably enough) "SelectedIndexChanged"

Good luck!

Re: reading text file and calculating the working hours for each employee

28-May-09 1:11

hi,
i tranced the o/p i have.the output i have isn't logic.
as it's subtract the date/time for today 28/5/2009 from for example:
Enroll No,78,date2,30/4/2009,time2,0:3:43,Check Out
the result is
No:78 Hours 14minutes2 Seconds 34

i should change this

DateTime date1 = DateTime.Now;
to refer to date1 from the file not for DateTime.Now;

but if date1=Convert.ToDateTime(rowaArray[3] + " " + rowaArray[5]); as they are same.
the result will be 0.
have you any idea to change this ?

OriginalGriff28-May-09 1:24

Re: reading text file and calculating the working hours for each employee

28-May-09 1:24

Yes. But you will hav eto do the work - it's not that hard!

Look at the data in the file you showed earlier:

Enroll No,194,date2,30/4/2009,time2,0:3:38,Check Out
Enroll No,78,date2,30/4/2009,time2,0:3:43,Check Out
Enroll No,78,date1,30/4/2009,time1,9:44:47,Check In
Enroll No,107,date1,30/4/2009,time1,9:44:52,Check In
Enroll No,108,date1,30/4/2009,time1,9:57:39,Check In
Enroll No,106,date1,30/4/2009,time1,10:40:47,Check In
Enroll No,109,date1,30/4/2009,time1,15:23:30,Check In
Enroll No,107,date2,30/4/2009,time2,17:6:27,Check Out
Enroll No,194,date1,30/4/2009,time1,17:9:44,Check In
Enroll No,132,date1,30/4/2009,time1,17:32:19,Check In
Enroll No,106,date2,30/4/2009,time2,17:35:31,Check Out
Enroll No,78,date2,30/4/2009,time2,17:35:41,Check Out
Enroll No,132,date1,30/4/2009,time1,17:45:2,Check In
Enroll No,108,date2,30/4/2009,time2,18:33:18,Check Out
Enroll No,109,date2,30/4/2009,time2,22:30:18,Check Out
Enroll No,194,date2,1/5/2009,time2,0:4:18,Check Out
Enroll No,132,date2,1/5/2009,time2,0:4:29,Check Out

Each line is a record:

Number 194 Checked out on 30/4/2009 @ 0:3;38
Number 78 Checked out on 30/4/2009 @ 0:3:43
Number 78 Cheked in on 30/4/2009 @ 9:44:47
and so forth...

This means you have to match up the check in with the appropriate check out, and work out the time difference - I am sure this is what the exercise you were set says (and I have never seen the exercise...)
The data you need is not all on one line. Think about what you have been taught in the course so far: I am sure that the structures and loops etc. cover what you need. Wink | ;)

Re: reading text file and calculating the working hours for each employee

28-May-09 1:28

can you suggest me a good book as i'm still a beginner.i take long time to think what the right thing to put.
i was reading visual c# steop by step..but didn't finish it yet.
thanks,

OriginalGriff28-May-09 1:59

Re: reading text file and calculating the working hours for each employee

28-May-09 1:59

I can't - there are so many of them, and for a complete beginner I really don't know - I came to C# from C++, and all the way back to assembler, so I started with knowledge you don't have and the books I used presummed that knowledge. Anything called step-by-step is probably a good starting point!

Don't think of it in C# terms: try to think "How would I do this if it was on a piece of paper?"

I would:

Call this "The List":

Enroll No,194,date2,30/4/2009,time2,0:3:38,Check Out
Enroll No,78,date2,30/4/2009,time2,0:3:43,Check Out
Enroll No,78,date1,30/4/2009,time1,9:44:47,Check In
Enroll No,107,date1,30/4/2009,time1,9:44:52,Check In
Enroll No,108,date1,30/4/2009,time1,9:57:39,Check In
Enroll No,106,date1,30/4/2009,time1,10:40:47,Check In
Enroll No,109,date1,30/4/2009,time1,15:23:30,Check In
Enroll No,107,date2,30/4/2009,time2,17:6:27,Check Out
Enroll No,194,date1,30/4/2009,time1,17:9:44,Check In
Enroll No,132,date1,30/4/2009,time1,17:32:19,Check In
Enroll No,106,date2,30/4/2009,time2,17:35:31,Check Out
Enroll No,78,date2,30/4/2009,time2,17:35:41,Check Out
Enroll No,132,date1,30/4/2009,time1,17:45:2,Check In
Enroll No,108,date2,30/4/2009,time2,18:33:18,Check Out
Enroll No,109,date2,30/4/2009,time2,22:30:18,Check Out
Enroll No,194,date2,1/5/2009,time2,0:4:18,Check Out
Enroll No,132,date2,1/5/2009,time2,0:4:29,Check Out

Get a blank sheet of paper, and a pen.

Look at the first line of the list, make a note of the Enroll number (194).
Beside this, I would write the date and time (30/4/2009 @ 0:3:38) and that this was a check out.

Look at the next line, and do the same. If the Enroll number is already on my piece of paper, then I would add the information to that, otherwise note it down separately.

Continue through the list doing all the lines.

I would then have:

Enroll No194 30/4/2009 @  0: 3:38,Check Out
Enroll No194 30/4/2009 @ 17: 9:44,Check In
Enroll No194  1/5/2009 @  0: 4:18,Check Out

Enroll No132 30/4/2009 @ 17:32:19,Check In
Enroll No132 30/4/2009 @ 17:45: 2,Check In
Enroll No132  1/5/2009 @  0: 4:29,Check Out

Enroll No109 30/4/2009 @ 15:23:30,Check In
Enroll No109 30/4/2009 @ 22:30:18,Check Out

Enroll No108 30/4/2009 @  9:57:39,Check In
Enroll No108 30/4/2009 @ 18:33:18,Check Out

Enroll No107 30/4/2009 @  9:44:52,Check In
Enroll No107 30/4/2009 @ 17: 6:27,Check Out

Enroll No106 30/4/2009 @ 10:40:47,Check In
Enroll No106 30/4/2009 @ 17:35:31,Check Out

Enroll No 78 30/4/2009 @  0: 3:43,Check Out
Enroll No 78 30/4/2009 @  9:44:47,Check In
Enroll No 78 30/4/2009 @ 17:35:41,Check Out

Now it is easy to see that:

No194 Checked in on 30/4/2009 @ 17: 9:44 and out on 1/5/2009 @  0: 4:18
so he/she was checked in for some 7 hours. 

No132 Checked in on 30/4/2009 @ 17:45: 2 and out on 1/5/2009 @  0: 4:29
so they were in for 6 1/4 hours or so.

All you have to do is translate that into the C# instructions you do know! I can't tell you what those instructions are because I don't know what instructions you do know - please, do not give me a list. Just have a try, it doesn't have to be good (or even work properly to start with) - you obviously know more than you think, since you are correctly using DateTime and TimeSpan structures already!

Post up what you come up with, and I'm sure we can get it working together. Smile | :)

Re: reading text file and calculating the working hours for each employee

29-May-09 23:02

hi,
sorry to disturb you again.actually i think text file won't be the ideal solution for me.the data you see before is from a finger print device.i can grasp it easily from the machine.i already tried to insert it into database but from the text file by using bulk insert.the problem is i will make update to the txt.file everytime an employee checked out or in.

I'm thinking now to make a database and make update on it or trigger.
I want to as how to grasp the data from the machine and insert into the database directly?
i just need steps...

thanks alot,
emmy,

You need to first bind the datatable with the combo box.
It should be something like this:

combobox1.DataSource = dt;
//Then set the datamember and valuemember as follows:

combobox1.DataMember = "Description";
combobox1.ValueMember = "Value";

//This will work...
And if not just write the value member first and then the data member...

Pleasae can someone help me. I have created a custom ribbon and am trying to implement it in an ExcaleAddIn and have created all the neccessary xml for it along with it's events as follows:

I have also created the callbacks for the OnAction event as such:
<pre>public void OnActionCallback(Office.IRibbonControl control, bool isPressed)
{

if (control.Id == "btnNewVersion_Click")
{
//MessageBox.Show("You clicked " + control.Id);
Form frmNewModel = new Form();
frmNewModel.Show();
}
else
{
MessageBox.Show("You clicked a different control.");
}
}

But i still can't get any functionailty out of it. I have successfully added the ribbon to the workbook as a tab but also have some default menu items displaying even after setting the StratFromScratch property to true.

Please help where you can.

Thanks

How about just increasing the number:

...
Student 99999999 : 99999999

stancrm26-May-09 22:22

If you want to add a new student, just get the record from database.
For example, the last record is number "10".
Then just give number "11" to the new student.
It's so easy.

The right way is to add a number automatically in database. It increase the number automatically
and the number is a primary key. That means the number is unique.
