Another way to eliminate problems caused by variant cultures is to use the IFormatter versions of ToString() etc. When dealing with file names, data stored in files, etc., specify CultureInfo.InvariantCulture. When displaying dates, integers, etc., specify CultureInfo.CurrentUICulture.
This gives you the best of both worlds - data interchange will work irrespective of the UI culture, and data will always be displayed in the current culture's preferred format.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Hi,
I have a table with 845 records, I Need to take 100 rows each time and push them to one service. This needs to repeat till records complete in datatable.
Help me on this.
With REgards,
Datta.G

int rowsLeft = yourDataTable.Rows.Count;
int batchSize = 100;
int rowsDone = 0;
while (rowsLeft > 0)
{
IEnumerable<DataRow> rows = yourDataTable.AsEnumerable().Skip(rowsDone).Take(batchSize);
rowsDone += batchSize;
rowsLeft -= batchSize;
}
|

|
|

A simple LINQ query using a combination of Take and Skip should get you the records. Take will get the records and Skip allows you to move past rows you have already taken.

hi
i have a server and many clients, the clients send a lot of request to server
i must keep them into a repository(queue) and do them.
my issue:
i need to a solution or pattern for when one of the request get exception or be failed , move to another queue and if in second queue get exception again go to another queue(just 3 level)
now I'll know how to management it
please help me
thanks

Sorry?
That doesn't make a lot of sense.
Perhaps if you give us an example, or run through the exact sequence of event you are having problems with in more detail?

It sounds to me like you're asking about using a MessageQueue. Windows comes with its own implementation (MSMQ) but there are others available. The syntax you use depends on which one you want to use.

thanks for your answer
i need to a pattern for manage my queue
for example my clients send requests to server and server tell to them i do it and you can continue,
now i must create a repository(include two or three queue) for hold the requests
the severe have a windows service that call queue and process the request
i think it's clear , but what is my problem?
for example the requests connect to each server for get data ,note i have a lot of requests
now i need to a pattern or algorithm that when a request for each reason be failed (for example time out or server is shut down for two hours or ...)
move the request to second queue (because if it stay in first queue,my queue be long and response to other requests be difficult) and i must define a scheduler for second queue and again process the request if get error again move to third queue. and define a scheduler for third queue with low priority
please if it isn't clear tell me
thanks

OK - that makes sense.
So what part of this is giving you difficulties?

thanks for your answer
implement it is my problem
i need to a pattern for identification the requests be failed
witch one is better two queue or one queue?
how to scheduler each queue ? (for example first queue must run non-stop and second queue what time must run)
when a request form fist queue move to second queue after scheduler do process again or move to first queue
please help me
thanks

I can't help you identify "requests that fail" - I have no idea what causes a request to fail, or how you detect it (remember, I can't see your screen or access your hard drive) - but as to the number of queues, that's easy.
Use multiple queues.
Have a "standard feed" queue, and move "failed" items to the "first generation failure" queue. If they fail again, move them to a "second generation failure" queue. (Use Locking to ensure thread safety while adding to or removing from a queue)
And have background tasks that periodically check the queue and retry. If the queue is empty, then it waits a while before looking again.
I'd probably add a timestamp to the "failure" queue, so I don't retry for a reasonable time, increasing with each generation.
But that isn't a pattern!

Or, as I indicated above, just use MSMQ - you kind of get this for free with it.

thanks for your tracking
i can identify "requests that fail", just if possible for you show me a solution or sample code for the rest of it,please.
and what is your suggest for use queue, for example rabbit or MSMQ or apachi.ActiveMQ or ...
thanks

Uhhh....there is no "rest of it". That code would be the bulk of your server and services! It's not possible for anyone else to write your code because none of us has any idea what you're doing, what types of messages your clients are supposed to be sending, what processing you need to do on these messages, what your validation and failure points are, what processing you need to do on a failed message, ... NOTHING.
The only person who's going to be able to write your code is YOU.
If you want examples on how to work with MSMQ, just Google for "C# MSMQ tutorials".

I just published an article on custom-drawing a Button control from scratch in Windows Forms, and after I published it, I found a link on this website that said that some articles are still in Pending status for a whole year due to being understaffed. Is that still the case?
I'm kind of scared right now. I don't want to wait a whole year! 
How long do new articles usually take to get approved these days?

Don't be, it'll take just few months  Just kidding!
The moderation is now done by the community so it'll take a short time to get responses and the article to be approved or rejected.
I had a look at it and as far as I can see there was no download included. I believe that adding a downloadable project would greatly help the article to be published.

Thanks for replying! I did upload files and a downloadable project though. I uploaded the whole C# solution inside a zip file. I will re-upload the files though and see if that fixes it.
|
|
|
|

After you have uploaded the ZIP, remember to use the "include selected files into the article" link just above the uploaded file list. Otherwise the zip doesn't become visible.

Ohhhhh! Thank you <a href="http://www.codeproject.com/Members/Mika">@Mika</a>, I didn't even see that option there.

Wrong forum You should ask here[^]. If you ask me, I think it'll be a bit quicker than that

Sorry about that Thanks for the link. And I sure am glad it doesn't take that long anymore! lol

Okay. Imagine this. You are sitting in a car waiting for your daughter's keyboard lesson to finish. You think you have some spare time to answer questions. Now picture your screen. How likely is it that someone sitting in a car can even begin to answer. In other words, you need to tell us what your code is doing. What errors you're seeing and so on.
|
|
|
|
|
OK. Your code is broken, so debug it, find out why it's not working and fix it!
There, you've been guided.
Really, what did you expect for an answer given the complete lack of information in your original post? We can't see your screen, your code, your hard drive, nothing. We have to rely entirely on what you put in your post to try and help with and what did you give us to work with? NOTHING.

Don't post this here - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.
