From the portion of code you have posted it looks to me like it is working as coded. Your program is a set of sequential operations which you try to run in parallel. So sometimes you get the result you expect and sometimes not, depending on which thread gets run first. Your use of threads in this case is superfluous as it does nothing to improve the program.
As Christian said earlier, you would be better to spend more time getting familiar with C# basics before worrying about multi-threading.

It seems to be a synchronization issue here. When you have the function call there, it slows down each iteration thus resulting in a different execution order of the concurrent calls. The fact that your output is right is coincidental because for a larger array, and on a different machine you may still see the unsorted or wrongly rearranged array.

Have you considered just using Array.Sort()? Implementing your own sort is usually a bad idea unless you know what you're doing... Especially if you're locking, unlocking, and redisplaying the whole thing each pass through the loop...
If you want items to show up in sorted order as they're added to the list, then just do that; use an insertion sort or equiv. and let it sort as-needed.
niranjanR wrote: I call showArray(N); before and after the execution of the sorting code.
See, this is what Nish is getting at: if you're running your sort on a background thread, you need some way of communicating your status back to the main thread - otherwise, showArray() will run too early (or too often if you also run it from the worker thread)...

I have 1 table student(ID,Name,Address).
and i make a stored procedure
<br />
CREATE PROCEDURE [dbo].[Proc_Scenario_GetMaxID]<br />
@MaxID as int OUTPUT<br />
as<br />
BEGIN<br />
if((SELECT MAX(ID) FROM student) is not null)<br />
begin<br />
SET @MaxID = (SELECT MAX(ID) FROM student)<br />
end <br />
else<br />
Begin<br />
SET @MaxID=1<br />
END<br />
return @MaxID<br />
END<br />
so i can't get the MaxID in C#.
Please help me !
sorry for my english.

Why can't you ? What have you tried ? ExecuteScalar may work, if not, just build a data reader and read your field.

How to get return value in C# code ? 
Thank !
|
|
|
|

So, if I get this right, what you're saying is that you don't know anything about C# at all and have done nothing to try to learn it ?

Sorry, i have learned C# for 2 weeks 
<br />
SqlConnection connect = new SqlConnection(ConnectionFactory.strconn);<br />
connect.Open();<br />
cmd = new SqlCommand("Proc_student_Add", connect);<br />
cmd.CommandType = CommandType.StoredProcedure;<br />
cmd.Parameters.Add(new SqlParameter("MaxID",varScenario.ID));<br />
<br />
With that stored procedured i can't get return value by "int i = cmd.ExecuteNonQuery();", please help me to resolve this problem.
Thank !

SqlCommand sampleCMD = new SqlCommand("SampleProc", nwindConn);
sampleCMD.CommandType = CommandType.StoredProcedure;
SqlParameter sampParm = sampleCMD.Parameters.Add("RETURN_VALUE", SqlDbType.Int);
sampParm.Direction = ParameterDirection.ReturnValue;
sampParm = sampleCMD.Parameters.Add("@InputParm", SqlDbType.NVarChar, 12);
sampParm.Value = "Sample Value";
sampParm = sampleCMD.Parameters.Add("@OutputParm", SqlDbType.NVarChar, 28);
sampParm.Direction = ParameterDirection.Output;
nwindConn.Open();
SqlDataReader sampReader = sampleCMD.ExecuteReader();
Console.WriteLine("{0}, {1}", sampReader.GetName(0), sampReader.GetName(1));
while (sampReader.Read())
{
Console.WriteLine("{0}, {1}", sampReader.GetInt32(0), sampReader.GetString(1));
}
sampReader.Close();
nwindConn.Close();
Console.WriteLine(" @OutputParm: {0}", sampleCMD.Parameters["@OutputParm"].Value);
Console.WriteLine("RETURN_VALUE: {0}", sampleCMD.Parameters["RETURN_VALUE"].Value);

That's a whole lot more work than is necessary, but I accept it would work.

If you've been learning C# for two weeks, why are you working on calling stored procedures ? There's no way that's a sensible next step for you at this point.
The MSDN site is a good place to look for documentation. You should really also own at least one C# book. Either way, ExecuteNonQuery returns a number that tells you how many rows were changed. The documentation will tell you this. I told you in the first instance that you should call ExecuteScalar, if you had any idea what you were doing, or willingness to do a little research, you should have been able to work that out. Even the intellisense would show you the answer.
If you're doing a course, you should talk to your teacher about getting some resources to help you do some basic research. If, as I expect, you're doing paid work, then you're yet another example of the disgraceful excuse for an industry that has popped up in the third world, where people with no experience work on paid systems and then expect the people in the West who lose their jobs to you, to do the work for you. There is no level on which someone who started to learn C# two weeks ago, should be working on this sort of code, unless they have sufficient experience in another language to be able to do some basic research for themselves and to understand a post like my initial reply.

CREATE PROCEDURE [dbo].[Proc_Scenario_GetMaxID]
(
@MaxID int OUTPUT
)
as
if exists(SELECT [ID] FROM student)
SELECT @MaxID = MAX(ID) FROM student
else
SET @MaxID=1
----------------------------
Because '@MaxID' is OUTPUT
So Your stored procedure...

Hello,
I want to create a simple alternative of PowerPoint slides.
I'll try to explain what I want to program.
I want a form that displays some slides which the contents are stored in the database. This can be a simple text, image or a video. I also want to have a kind of Marquee on bottom of the form. I thought about using DirectX for smooth Marquee, but don't know if that will be the best option. So I want to ask you guys what I better can use.
Greetings,
Abadi

I'm not saying that what I am going to suggest is 'better' than DirectX, in terms of smoothness and control DirectX will probably be 'better'.
If you go to the Code Project Home Page and type c# marquee into the search box at the top you will find several 'marquee' controls. Have a look at the code they contain and see if you can use it.
Also on MSDN there is an example Walkthrough: Creating a Windows Forms Control That Takes Advantage of Visual Studio Design-Time Features [^] that includes a marquee control.

Check the value of xcontrol. If it's never anything other than 0 or 1, then you'll keep calling Lhesaplax and never hit your base case to exit the recursion.

I need to read a file from over 200 pcs on our network using a C# application. This file might not exist so creating it is an easy process--just running a command from the command line on remote pc. I found a tool called psexec which allows running commands on remote pcs: I simply use this tool and run the command. However, it takes very long and I have to keep checking if the file exists. If I run the command on the remote pc right at the remote pc then it is instantaneous.
Is there a better alternative? I simply need to do the following:
1. Check if a file exists and delete it.
2. Recreate the file by running the command on remote pc.
3. Read the file.
I am sure others have had to do this before.

Assuming that your Primary Key Column is an Identity column this[^] might give you some ideas. At the very least, some terms to google for.
Good Luck!
