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 | :)

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...

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

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.

I would suggest storing the number in a file outside your app and then read that number when processing a form. Once form has been processed just update the number to the next. This is how I currently do it to store version numbers for batch files generated from my apps.

Are you storing the information in a database? If so, get the database to create the id for you. Make the primary key (the registration number) an identity column and your registration number will be generated upon insertion to the database.

If you storing the information in some other manner, you'll need to just build a counter to increase the registration number by some amount (could be 1, could be more in order to validate a number as a valid registration number and avoid typos) each time. If this is a serious application then you'll need to make sure you do this in a common place (singleton) and that this action is threadsafe.

Rob Philpott.
