"I want to change their email domain" - and the issue is...

Not a question at all!

"Not work propelry" is not informative at all!

On the first lok, below statement:
CAST(DATEDIFF(Minute,FromDate, ToDate) / 60 AS VARCHAR(5)) + ' Hrs' + ':' + RIGHT('0' + CAST(DATEDIFF(Minute, FromDate, ToDate) % 60 AS VARCHAR(2)), 2) + ' Min' AS 'Hr'

returns strings like this: 9 Hrs:22 Min
So, you can't simply sum up values stored in such of string. You need to remove "Hrs" and "Min" from that string, then to split string into 2 fields: hours and mins. At the and, you'll be able to sum it up!

Such of statement: var sentence = from l in doc.Descendants() select (string)l.FirstNode.NextNode.NextNode.ToString() is incorrect.
You should provide more details about your issue, especially what you want to return.

If the first element of array is on position (index) 0, then the 4. element of array points out to... nothing (out of array).
------------------------
index: | 0 | 1 | 2 | 3 |
------------------------
array: | 1 | 9 | 8 | 7 |

You should carefully read my answer and related articles first rather then tranfer your angry onto me.

There's no need to "cast the result to an array", becuase Join method acceppts IEnumerable(Of T).

Dave, there's no need to install Access 2003 Runtime. As you mentioned, installing Access 2013 (or 2010) would be enough. At this moment i do not understand what OP is trying to say us. Is He using WinForms on IIS server?

Player 119 played 2 matches with the same ID. So, your query will return 2 matches, but OP wants to return only 1. Got it?

Chris, thanks for explanation.

Graeme, forgive me if i offended you. It wasn't my intention. I started my programming journey with Pascal and VBA. I have got medium experience with C++. Now, i'm using VB.NET and C# (prefered). As you can see, i'd be able to provide 5 solutions, but the idea to resolve issue would be the same. So, i'd rather to provide one solution (in any language). That's my point of view.

Chris,
Can you tell me the most important idea of coding challenge? Till now, i've been sure that the most important thing is to provide one unconventional solution, but now i see that coding chalenge has been changed into "How many programming languages you know?". I'd suggest to post the rules of coding challenge. If the method of resolving issue is the same (the same idea), the count of solutions couldn't be the reason of glory (upvotes).
Note: i see nothing wrong with six or more solutions of Graeme_Grant: F#, Linq and non-Linq version of C# and VB.NET, PowerShell, BatchScript, WPF(?!?), but... it stinks of bragging.

Does CFP_ID field is numeric data type? Seems, it's numeric. So, why you're using '' aroud its value? This causes the database engine to treat it as string value.
I'd try something like this:
Hide   Copy Code
Dim cb As String = "Update CourseFeePayment set PaymentID=@d2, AdmissionNo=@d3, Session=@d4,TotalFee=@d6, DiscountPer=@d7, DiscountAmt=@d8, PreviousDue=@d9, Fine=@d10, GrandTotal=@d11, TotalPaid=@d12, ModeOfPayment=@d13, PaymentModeDetails=@d14, PaymentDue=@d16 where CFP_ID=@d1"

Well... a challenge has been defined as: Given a collection of items (...whatever) determine the set of subitems in that collection that are repeated. So, there must be some way to compare objects. IEqualityComparer seems to be the best way for object's comparison.
Maciej Los 15-Feb-17 1:50am View
   
In a short: because of usage IEqualityComparer<T>, so any of data type can be used.
