NB: If you're writing a web application, don't use Excel Interop. It's not supported:
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
Assuming you're uploading a new format file (.xlsx), any of the following libraries should do what you need:
If you need to support old format files as well (.xls), then you'll need to use NPOI[^].

Excel work sheets / files can be saved as CSV or XML (among other things); which are, in other words, "strings".
You can store or transport Excel files anywhere if you simple treat the file (contents) as a "long string".

Hi
I am updating record in c#
table name 'Person' .Table structure
Manager_ID int
Employee_ID int
Approved bit
Manager_ID Employee_ID Approved
123 1 0
the Manager who logs in is Manager_ID
the person targeted is Employee_ID
Approved is set 1 or 0
we assume already record is inserted.
query to be Updated is given below.
Update Person set Approved=1 where Manager_ID = 123 and Employee_ID =1
now alert will go to Employee(Employee_ID =1 ,if he logs in) from Manager .
both update query and alert will occur at same time
I am using visual studio 2012 ultimate ,dot net framework 4.6 ,sql server 2008 ,c# and windows 8.1
Thanks and regards

That's how it works.
You could add a timestamp to your recordset that is updated whenever something is written; that way you could ask for the changes of the last five minutes, for example. Alternative, you could calculate a quick hashcode, and compare those to see which of them changed.
Good luck

Why don't you create a separate record for each update so that the live versions are not tweaks every now and then?

I'm writing application in C# (WPF, .net 4.5). I need library for decoding barcodes (EAN128, GS1, code 128, EAN13). Can anyone suggest me ready to use library (free or paid). My scanner connected by USB reads a barcode and sends string od chars (mostly numbers) and I need to decode it to separated PLU, LOT, BBD etc.

does your bar code scanner manufacturer not have any examples to start from?

I think what you need to do is to start looking at what is in a barcode: GS1 isn't a barcode (it's an allocation system for barcode numbers), EAN-13 only provides an Article Number, and Code128 is a transport mechanism that allows EAN128 to contain more than just numeric values. Only EAN128 contains specific fields you can decode into PLU, Serial Number, batch codes, etc. And most of them don't bother: they just contain the Article Number.
Normally what happens is that the AN is read from the barcode, and used as a lookup to your stock database to determine what type of goods it is, what price you are selling it as, and so forth.

I know how barcodes work. I'm working about 12 years with ERP systems that use barcodes. You're right - GS1 it's not a code - it's non-profit organization. I thought about GS1-databar.
EAN13 not only provides Article Number - it also can contain weight or price of article.
My application send string from barcode scanner and only one think I need is to get this string separated into detailed data for example batch after 10, BBD after 15/17, weight after 310x etc. I know many of AI but I need solution which knows all of possible AI and will search string from barcode and seperate data after AI. I don't want to write it from the beggining because I don't want to miss any AI etc.

EAN13 holds only a 13-digit article number: you are thinking about EAN13+2 and EAN13+5 which are extensions to the basic EAN13 spec - and there isn't anything which says what those additional digits must be: they do not have to be weight or price.

We are using EAN13 that contains only 13 digits and in this 13 digits is price or weight with article number without any extra 2 or 5 digits - it's always 13 digits EAN13 code.

If that's true - and I don't believe it for a moment - then what you are doing is probably very dangerous in commercial terms. The only values allowed in an EAN-13 standard bar code is a single Article Number, which is assigned to a comp-any for a specific product by the appropriate national body (for a charge) in order that it is unique world-wide. All POS systems read the barcode, extract the AN, and use it for a DB lookup to identify the exact product scanned, and from that same DB get the weight, price, dimensions, manufacturer and such like. None of that is directly stored in the BC - it's all DB stored and linked to the AN received from the BC.
If you are storing weights and prices in the AN, then unless you have purchased a pretty huge block of ANs from your issuing authority, then you are probably issuing items with EAN13 BCs which identify them to the real world as toothpaste, or rubber gloves, or fresh chicken portions ...

This's not our standard code - we have to print it because some of our clients need such EAN13 code - this code is printed on label only if our customer wants. Clients send us specification of codes which they want from us. Clients' POS systems reads it correctly.
This is just a market need.
|
|
|
|
|
Then you will have to read your clients specification, because what you are doing is non-standard so we cannot tell you what parts of the code you need to extract, or how they are encoded...

I only wanted to show you that EAN13 can also contain weight or price because you wrote that EAN13 contains only article number. My question was about decoding string not only from EAN13 which are the easiest to do - most of all I need help with EAN128, Code128 where are many possibilities and AI.

If it's a "custom code", then it's not EAN13 or anything else "published"; so stop referring to it in that way. Call it what it is: a custom (barcode) encoding.

That's how they work. They decode the barcode and send you the string of characters. From there, you just do whatever you need to do, for example, lookup the value in a database.
There are only 10 types of people in the world, those who understand binary and those who don't.

A barcode reader is just like a keyboard. After is scans the code it decodes it and sends you like it was an input string... To try and interpret the scanned image by yourself will be a total waste of time, and a sure way to errors...
If you have to handle specific barcode formats, buy a scanner can handle it...
