If you're using a 32 bit version of windows, the maximum memory space for an application is 2gig (3 if you fiddle some system settings), so you might find you can't hold the whole file in memory

how to tranfer file using Filestream through sockets using UDP in c#..?
I've tried file streaming but at Recieving End i m unable to get the byte recieved in my recieving buffer as RecieveBuff.length() gives the length of buffer but not the total bytes recieved in buffer.
ForExample at rcving end length of buff is 8KB but if last sending packet is of 2KB then how Could I retriev just 2KB as it append the 6KB of garbag data into buffer.
SO PLZ HELP ME OUT ASAP.
Thanx.

Think in Datareaders. If you use it,you open, read and time after you close it. If in this period you try to open another from other thread you will get an exception.

Hi - this is actually the third time you came to this site asking the same question.
It looks like you really need to post to a Crystal Reports forum not a C# forum. Have a search on google to see what you can find.

If the OP who just deleted his post is still around - please don't delete above a thread - it messes up the forum.
I wasn't being unjust - I just didn't want you wasting your time asking the same question in the same place many times and not getting any results.

I am not too clever, if I was, I would have answered your original question. I use what ability I have to the best of it. Always. I was simply trying to help - it is pointless posting the same question over and over.
I hope you find your answer, and if you do, write an article for Code Project on Guntt Gantt Charts in Crystal Reports for C# - thereby helping others.

This is no different to putting urgent plz help in the title. You are not being polite to other posters by doing this because you are assuming that your post is more important than theirs. Just because it is the most important thing that you are dealing with, doesn't make it any more important or urgent than things that other people are dealing with.
This site is volunteer only. If you feel that you really need this information ASAP then you need to consider paying for a support call with Business Objects (or Crystal Reports - or whatever they are calling themselves now). That way, you can guarantee that people will take a look at your problem ASAP.
The problem that you now have is that people know that you repeat post the same issue. This meanst that people are more likely to ignore your posts because they think that they are a repeat of things that have already been posted about.

Hi,
I have some Static label or Some Rich Text label that i set to it in Run Time some String.
In case the string is too long ( the size of the Static label or the Rich Text label is not auto size ( i mean that the size is const ) ) there will be some Tool Tip with the all string.
My question is ... how can i know if the string is too long ?
Is there is some way ?
Thanks for any help.

class myClassThatHoldsTheString
{
const int _myToolTipLength = 50;
private string _myTooltip;
public string MyTooltip
{
get { return _myTooltip;}
set {
if (_myTooltip== value)
return;
if (value.Length > _myToolTipLength)
_myTooltip= value.Substring(0,myToolTipLength );
else
_myTooltip= value;
}
}
}
myControl.Tootip = myInstance.MyTooltip;

I've just re-read the OP question and think I have answered totally the wrong thing...but I am leaving it here anyway!

As i still dont have much programming exp., so there are some question of mine which want as answer.......
-> If i created a peice of code and its working, then i dont even think wheather it is good enough or not, i mean is there other better way?
So, how to analyse this?
(plz dont measure performance in neno-second(resources), as in small application it hardly matters)
-> How to analyse the worst case possibility of code?

if u r using a backend it really matters

Performance and properly architected code matter in all cases. Also, please use proper english and not SMS (Text) Speak in the forums and don't advertise.

This really depends on what you want to analyze. If you are just looking for performance measurements, you can do order analysis or wrap sections of the code in timing blocks. If you are looking for best practices type analysis, you can run tools like NDepend[^] or FxCop[^].
There are a lot of design resources available through CP, the web, or books as well that can give you good design patterns to start to follow.

Learn to spell 'should'
Pick out a small section of your code, a small class, or a few methods and post it here, asking people to critique it for you. Don't post your whole application though.
Whilst this is strictly a forum for answering problems regarding C#, considering the amount of dross that is being posted recently, I imagine you will get loads of people offering advice on how your code can be improved, and constructive criticism on what you have done.
If others don't agree with me, the worst you will get is a few '1' votes (and I'll get a few more for suggesting it!!)
<edit>
Unless you're from NIIT - then you're on your own! (sorry, I have a problem with NIIT students on here at the moment - hopefully one of them will prove me wrong soon.)

I don't think that's likely to happen. They really do seem to like being the dross on the net.

I think that you need to learn to program and experience the mistakes. I learned programming with falling and standing up. Wrote brilliant code that later-on was a piece of crap caused by performance issues. Well this you learn while you are learning and doing.
How you can test if your application is doing fine, work with it.
Your application works fine with a small amount of data, what if you multiply this small amount of data by 1000?
Is my application slowing down? Do I make to much Interface call backs during the process?
Besides that, there are in the market profiling tools that can point out code that is taking to much time to run. Think of ANTS profiler and JetBrains.

I haven't looked too closely at your code but you'll receive a datareceived event as soon as the first byte comes in. Sounds like you're then trying to read everything that's arrived. Most of your data will still be yet to arrive.
Try reading a byte every time you get the datareceived event and then assembling them as you see fit.
This assumes you have set the serial port to send a datareceived event for every byte. If you've set it for more then read as many as you've set.

Dudes,
Why is it that everytime i download a csv file it will include the default.aspx

--> but it always include this
...
...
...
heres my code:
string filename = "default";
Response.Clear();
Response.ContentType = "APPLICATION/CSV";
Response.AddHeader("Content-Disposition", "Attachment; Filename =" + filename + ".csv");
Response.Flush();
Response.WriteFile(Server.MapPath("~/doc/default.csv"));
Did i miss something?

Hello All,
I have two tables First one has PK auto increment column and the second table Has FK I select the last inserted PK in the First table and insert it into the second table as FK. is there is any more professional way to do so or this is the correct way?

If you're using SQLServer you can get the value of @@identity. It's a sql server var that gives you the value of the last autoincrement assigned.
