Owe, thats the cute idea. Thanks a loooot. Sure, it is a working code and it is working perfectly. Thank you very much for your help.

No, The data lives in the web servers session context, your just writing code that talks to the web server if the data exist. So you also need to make sure that the data exist before you ask for the data, or else the code will bomb with an object not found. Once the session expires, usually 20 minutes, that's it, the handle to the web servers session context is deleted, and your data is cleared. You can't store session data forever, it's has a short ( finite ) lifespan. If you want to store temporary data, then you write to the database on the server side, or write a cookie on the client side. And ask the browser for the cookie if it exist thus - Request.Cookie 3rd edit: Don't worry about the code, or whether it is public or private. Technically, the object should already be global, in which you can access the data on another web page using the same code. If your using the code to remember who the user is, on many pages after they sign in, then your alright. Just make sure to check the identity when needed.

Oops, sorry, this is my first post and I couldn't see that the question was already answered. Please ignore. I am not sure if I understand the question but here are the results of my testing... -- Original query with bits added in so I get a result set DECLARE @totalIds INT; SET @totalIds = 2 DECLARE @DeletedIDArr VARCHAR(50) DROP table #deletedIds SELECT * INTO #deletedIds FROM (SELECT 1 AS Id UNION SELECT 2) a DECLARE @Iterator INT SET @Iterator = 0 WHILE (@Iterator < @totalIds) BEGIN IF(@Iterator = 0) BEGIN SELECT TOP 1 @DeletedIDArr = CAST(Id AS varchar(50)) FROM #deletedIds END ELSE BEGIN SELECT TOP 1 @DeletedIDArr = (@DeletedIDArr + ',' + CAST(Id AS varchar(50))) FROM #deletedIds WHERE Id NOT IN(SELECT TOP (@Iterator) Id FROM #deletedIds); END SET @Iterator = @Iterator + 1 END SELECT @DeletedIDArr -- My version SET @DeletedIDArr='' SELECT @DeletedIDArr = @DeletedIDArr+CAST(Id AS varchar(50))+',' FROM #deletedIds SET @DeletedIDArr = LEFT(@DeletedIDArr,LEN(@DeletedIDArr)-1) SELECT @DeletedIDArr

Thank you so much for the ideas. Yes, you are right and thats what I am realizing now. At this moment, I am avoiding the extra BLL layer, but I will keep a sharp eye when duplication of code is apparent, and only then, I will add the BLL with only the refactored common methods. So, some of my UI will call DAL and some of my UI will call BLL and over time, depending on BLL will be increased and DAL dependency will decrease.

The data should not be in the program directory.

With specific information about the functional needs of your application it might be more relevant. Reliability on the other hand could be a factor. Portability is probably meaningless because anything that is going to run .Net is going to be able to run SQL Server. Presumably there is no intention at all, under no circumstances, where more than one user of the database is required. If so then SQL Server is probably a better choice. Installation can be made a non-issue by providing an installer that installs everything.

Thanks for the keyword 'Client Server (Network) Programming'. I searched in Google with 'Client Server Programming in C#' and found the VERY RIGHT article that just solved my problem. Here is that article : Introduction to TCP client server in C#[^]

Any assemblies used in your application will use the configuration file from the main executable, unless otherwise specified. Copy the settings necessary for your data access layer to the web.config file. I know the language. I've read a book. - _Madmatt

Hi, Thanks for your reply. Actually I am concerned about the overall speed, So, let assume that, the time taken in server for FILE IO operation and image size calculation is = Ts And the time taken in client for image size calculation on the fly is = Tc, I need to know, if Ts > Tc or Ts < Tc. If Ts < Tc, I will use server side code to calculate image size, I dont care about server load as the page I am rendering is a protetected page, only one user can see that page. If Tc < Ts, then, I will let the browser calculate and display the page. So, can you please tell me which value is higher ? Ts or Tc ? It is very hard to experiment and find out these values, so I thought if this information is already known by others, it would be helpful. Regards.

You need to use Linq Expression objects to get the name of a property, from the property itself. Here's a simple test program that demonstrates what you have to do: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.ComponentModel; using System.Linq.Expressions; using System.Reflection; namespace ConsoleApplication4 { class Program { static void Main(string[] args) { Consumer c = new Consumer(); c.TestIt(); } } public class Demo { public int InstanceProperty { get; set; } public string InstanceField; static public int TypeField; static public int TypeProperty { get; set; } } public class Consumer { public void TestIt() { button1_click(this, new EventArgs()); } private void button1\_click(object sender, EventArgs e) { Demo myDemo = new Demo { InstanceProperty = 10, InstanceField = "Kab" }; string n1 = GetMemberName(() => myDemo.InstanceField); string n2 = GetMemberName(() => myDemo.InstanceProperty); string n3 = GetMemberName(() => Demo.TypeField); string n4 = GetMemberName(() => Demo.TypeProperty); string n5 = GetMemberName(() => myDemo); // This was a surprise - I expected it to fail! } private string GetMemberName<T>(Expression<Func<T>> itemSpecifierExpression) { var bodyAsMemberExpression = itemSpecifierExpression.Body as MemberExpression; if (bodyAsMemberExpression == null) throw new ArgumentException("itemSpecifierExpression does not specify an object or an instance or type member"); var propInfo = bodyAsMemberExpression.Member as MemberInfo; return bodyAsMemberExpression.Member.Name; } } } Note - it may be possible to simplify things a bit, but I've not used Expression enough to be sure. See INotifyPropertyChanging[^] by atverma[^] for the article where I first saw the technique used.

Hi, This is looking great. Quick question, is there any way to modify this code to allow for inner class conversions too? My classes have inner classes and these too differ by name space. I have no idea how reflection works so if you could be kind enough to point out a solution for me it would be great. If not, I'll try to figure it out :/ Thanks a lot for your time.

Thanks, actually I did not mean the Login Control, rather, I meant the LoginName control. But anyway, I have solved the problem by developing a new custom control from scratch. :) Regards,

You can put the NOINDEX meta tag on your page to prevent indexing the content. <META NAME="ROBOTS" CONTENT="NOINDEX"> Without it, I'm afraid Google will be indexing your login page. Returning 301/302 status doesn't really bother google with regards to page rank, a 301 will only prevent google from spidering your original links in future. Freestyle Interactive Ltd | Martin on .Net
