The user probably cares; he is sitting in front of the monitor waiting 23 seconds for things to happen. With a CPU load of 100% it might last only 8 seconds. And with a better design probably only a fraction of that.

Sadly, what doesn't show up in the 30% is all the idle time the CPU has waiting for disk I/O to complete.
If the CPU is at 30% during all of this, there really isn't too much he can do, other than redesign and try and bypass the off-CPU bottleneck.

Disk I/O can be a factor, but I understood with arrays, i.e. without DataTables, it only took 2 seconds; so everything exceeding that needs scrutinized.

I wonder about his users! If they're complaining that it takes 2 seconds longer to get a Desktop they can use, they really need professional mental help! 
Where I work, it can take upwards of 10 minutes (worst case) to get into a machine on the first login! My laptop takes 5 minutes to get to the point where I can use it! 23 seconds is nothing...

I feel for ya! Thats horrible, luckily we have all new machines here and usually within 10 seconds of logging in the users is fully able to use machine.
I'm also in charge of the login scripts and we keep the stuff it does to a minimum. User impact will be minimal but there is a perception with the users that their computers are slow if we have stuff like this happening. They don't understand it's poor programming, nor do they care.
I actually started writing out console.writeline with time stamps through the loop process of writing the data to the datatable and it was taking 80-120 ms per user in loop. It takes 10 ms for example to create a new row.
I did change two things and was able to shave about 2 seconds off. Something doesn't quite seem right because I was talking to a web developer friend up here and they have a web database that can write/query 40k records in about 5 seconds.
He said my code looked fine also. I'll mess with this in a day or two when I have more and post an update for those of you curious.
Either way I appreciate all the advice everyone has given.

Hi ,
I have a asp.net application which was built in vs 2005 sp using .net framework 2.0 sp1.
when i used the same application in vs 2005 RTM with .net framework 2.0 sp2 , am getting a
lot of errors (compilation).
Is the change in service packs effects this scenario in any way?
Thanks in advance!

Sounds likely. If it worked before, and doesn't work now and the only thing that's changed is the service pack then it stands to reason that this is the problem.

look at the first compilation error first. Maybe show us some...

And what does this have to do with the .NET Framework??

What are you trying to do with this?? Have you added other files as resources??

You can try this tool[^]. I'm not going to say it'll work, nor will I even support the idea. What you're doing is not an accepted practice for a production quality application. Nor is there very much reason to do what you're attempting. Files like this are best left outside the .EXE since modifying an .EXE always risks damaging it to the point it'll never run again without being scrapped and reinstalled.

Hello,
my MDI application includes child windows having the FormBordStyle property set to SizableToolWindow, so the Maximize and Minimize boxes are hidden.
Nevertheless, the child windows can still be maximized by double-clicking on the title-bar; how can I inhibit this feature?
Thank you
|
|
|
|
|
Did you change the FormBorderStyle of this window to FixedToolWindow, or SizableToolWindow?? Hint, hint...
|
|
|
|
|
I changed the FormBorderStyle to SizableToolWindow, since resizing the child windows (by dragging a corner or a border of the window) is allowed in my application.
I just want to prevent child windows from being maximized as a consequence of a double-click on the title-bar.
|
|
|
|
|
In that case, you're going to have to handle the Resize event of your child form. In that handler, check for the windowstate property, and set it back to Normal if it is Maxmimized.
|
|
|
|
|
That's exactly what I was looking for!
Thank you very much.

Hi,
I have been investigating y dot net applications are using more memory while startup, it has been suggested to use performance monitor instead of taskmanager.
Can u please let me know how to use performance monitor for knowing the actual memory usage.
Thanks

You don't need to investigate it. It's been well discussed and documented already.
Read here, http://getdotnetco.web119.discountasp.net/GdncStore/free/Articles/The%20Memory%20Mystery.htm[^] and the other links I gave you last time.
.net memory is not something you need to worry about. Just trust the CLR. Unless you are doing some serious, cutting edge, right on the metal, hardcore processing, the CLR is efficient enough for you.
Rather than measuring things like memory usage, measure things like perceived performance. If your app starts up quick enough, and responds to user clicks fast enough, why do you care about how much memory it is using. Just let the CLR handle itself.
Instead, learn how to write efficient and optimal code within the CLR environment. Learn about the dispose pattern, learn how to manage your resources and learn about the pros/cons of the different data types, structs and class, and the passing semantics (by ref/by value etc)

Hi all,
This is senthil. I got a project(with codes and design) from my client to upgrade.
The project is mainly developed in vb.net (from the design pages i got this information).
In the project code-behind files are separated files.
But the project is not having these code-behind files. And the pages is also running without any failure in the server (with absence of these code-behind files). For upgrade purpose i opened the pages through vb.net IDE, But the code-behind files are not founded.
How this is possible.
Is anything i need to know.
I need these help urgently....
Note* - I didnt convert/migrate the project.
And the developed .Net IDE is VS 2005.
Thanks in advance

Simply the folder you have is a pre-compiled published version of the application where there is no codebehind files exist and everything is converted to dlls !

I'm making a login page with ASP.NET with C#.
and I know that it needs to use Session for saving information of loggined user.
so I used Session like this on "login.aspx.cs" with Login View Control.
[login.aspx.cs]
// Database query.
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Join"].ConnectionString);
SqlCommand cmd = new SqlCommand("SELECT * From User WHERE id = @ID", con);
cmd.Parameters.AddWithValue("@ID", ((TextBox)LoginView1.FindControl("TextBox1")).Text);
string name = rd["name"].ToString();
string pw = rd["password"].ToString();
string pw1 = ((TextBox)LoginView1.FindControl("TextBox2")).Text;
string id = rd["id"].ToString();
// Save to Session variables. There are a lot of components about Session. Keys, Item, Add,
//and so on..
Session["memberid"] = id;
Session["membername"] = name;
if ((string.Equals(pw, pw1)) == true)
{
FormsAuthentication.RedirectFromLoginPage(name, false);
}
....
And I made codes like this whether lggined user is same with Writer on board or not.
[Board.aspx]
public static bool IsWriter(string pdsId, string Writer)
{
string sql = "Select id From t_Pds Where boardId = @boardId And writer = @writer";
SqlCommand cmd = new SqlCommand(sql, DbConn.GetConn());
cmd.Parameters.AddWithValue("@boardId", pdsId);
cmd.Parameters.AddWithValue("@writer", Writer);
cmd.Connection.Open();
string result = (string)cmd.ExecuteScalar(); // result = ID of writer value.
cmd.Connection.Close();
// I can't use Session. When I use "Session", there are no components of Session.
// There are only two values of Session. ( SessionPageStatePersister , SessionParameter)
if (Session["memberid"] == result) //ERROR.
{
return true;
}
else
return false;
}
}
How can I use Session for saving information of User and how can I compare with Writer on Board?? Is there sample code??
