Running Different .NET versions in ASP.NET / Application Pool
Ken Egozi : IRresistible - Running ASP.NET applications of various versions side-by-side: "Running ASP.NET applications of various versions side-by-side
Some annoying problem I've encountered lately.
While developing on my XP machine, I have had some ASP.NET 1.1 applications and ASP.NET 2.0 applications running side-by-side, as virtual directories on the single website allowed by IIS5.1
When I've published an ASP.NET 2.0 application to a production server, running IIS6.0 (on Windows 2003 Server) with already installed ASP.NET 1.1 applications, I've found out that if the old applications are running, the new one returns 'Server Application Unavailable', and vice versa.
A quick search in the Event Viewer revealed that IIS isn't fond of running applications of different ,NET runtime version, in the same process. Quite reasonable that is, yet annoying.
That's when I remembered that I've always said to myself that I should look into the reason that IIS5.0 and IIS5.1 runs each ASP.NET application in a aspnet_wp.exe worker process, while IIS6.0 uses a single w3wp.exe worker process.
A little web search and I've found this: http://technet2.microsoft.com/WindowsServer/en/Library/d0a61f24-942e-4379-adad-8232be03441c1033.mspx, and adjacent pages.
So this is a new feature of ASP.NET, that makes it possible to run a few applications in the same process. Every few applications (virtual directories) are assigned to an application pool, and each application pool runs in its own process.
There are a few settings that can be done for each application pool. Those settings are overriding the defaults in the machine.config file.
Adding an application pool is done through inetmgr.msc, by just adding a new pool to the Application Pools section. Use the option to copy settings from t"

Great Online Ebook on C# Threading
c# supports parallel execution of code through multithreading. A thread is an independent execution path, able to run simultaneously with other threads.
A C# program starts in a single thread created automatically by the CLR and operating system (the "main" thread), and is made multi-threaded by creating additional threads. Here's a simple example and its output http://www.albahari.com/threading/

A Primer on Using DB2 with .NET

Introduction
Working with DB2, from a .NET application developer's perspective, is just like working with any other relational database. One can find endless examples of how to perform databases tasks (from the mundane to the interesting) for Microsoft SQL Server and Oracle, but there is not as much similar documentation for accessing DB2 from Microsoft technologies, including .NET.
A developer currently has different access techniques to programmatically connect .NET programming clients to DB2. For each of these the code is basically the same thanks to the providers involved, but some interesting limitations exist that you should consider."

.NET XML Web Services Repertory
http://www.xmlwebservices.cc/index.htm
Christian Weyer is an expert for Microsoft and Web technologies with focus on .NET. Since the end of 1999 he plays and works with XML, SOAP and related Web Services technologies with having a background of DCOM, CORBA and Java. Being a founding partner of thinktecture he regularly speaks on developer conferences and other events - lately he has been elected as an official speaker for the European INETA speaker's bureau. Christian writes German and English articles about the latest and most promising technologies.Additionally, he is an MVP for ASP.NET and XML Web Services for being very active and knowledgeable in the .NET and Web Services community. Christian is also a Microsoft Regional Director for Germany.His hobbyhorse all around .NET and XML Web Services is the site known as '.NET XML Web Services Repertory'. This place is dedicated to building Web Services on the .NET platform, especially focused on ASP.NET. Here you can find lots of sample code (also available as online demos), a Web Services FAQ, an Essential Tools overview and a growing collection of useful links. Additionally it provides information on interoperability and integration with other SOAP or Web Services platforms - e.g. Systinet WASP, Apache SOAP, Apache Axis or IBM Web Services Toolkit.

How to create a simple setup program for your administrator to run.
How to create a simple setup program for your administrator to run.
This post is better read in mono-space format.
Scenario: As usual you don't have the access right to do ClickOnce
'publish' option. It's just how big companies work so
you have to work with the deployment team.
Well, your ever witty manager tells you to write
an install file that will automatically unzip and copy
the deployment files. Let the administrator run it and
never you.
You know exactly that a virtual directory already
exists and the exact location of this in the server.
Say example "c:\inetpub\wwwroot\MyClient" It
was setup before by someone.
Let me think:
I can create an msi file but it is too much. Hmm...
I can not use Visual Studio 'Setup Project' to create
one msi because it is too much work. Besides it
is considering dependencies like .NET framework
automatically. The thing I don't need here.
So what do I do???
My Solution:
Use 7zip file to create a self extracting file.
It is open source and free It can be downloaded at 7zip.org
The instructions are less clear in 7zip.org but you can
follow it after a few trials. Don't worry, to speed
you up I will describe an example setup.
For example. Imagine you have a directory like these
note ('\' means a folder)
C:
|
+---\WorkArea
|
+---\ClickOnceFiles
| |
| +---\MyClickOnceApp_0_1_0_4
| | |
| | +--
| |
| +---MyClickOnceApp.application
| +---MyClickOnceApp_0_1_0_4.application
| +---publish.htm
| +---setup.exe
| +---run.bat
|
+---\Output
|
+---7za.exe
+---7zSD.sfx
+---config.txt
+---create.bat
First, you can publish locally to your computer to the
'ClickOnceFiles' Folder as above.
Secondly, note that 'run.bat' is copied inside the folder
together with the ClickOnce deployment files.
This is intentional because it will part of the zip
component.
All you have to do is the run CREATE.bat, and it will produce
MySetup.exe in the output directory.
Yes, give MySetup.exe to your system administrator.
(better give its md5 hash also for peace of mind).
And you will look 'cool' from now on.
-------------
Ok, now the descriptions and contents of these files.
The files 7za.exe, 7zSD.sfx can be downloaded from 7zip.org
Look for 7z Library, SFXs for installers
create.bat
----------
del TempFile.7z
7ZA a -r TempFile.7z C:\WorkArea\ClickOnceFiles\*.*
copy /b 7zSD.sfx + config.txt + TempFile.7z output\MySetup.exe
del TempFile.7z
config.txt
----------
;!@Install@!UTF-8!
Title=" Client ClickOnce Files Setup- (C)2006 "
BeginPrompt="Do you want to update Client Deployment Files?"
RunProgram="run.bat"
;!@InstallEnd@!
run.bat
-------
(I know, I know this is not optimized, you can probably use variables
to store the virtual directory path, etc...) but here it is.
@ECHO OFF
CLS
IF NOT EXIST c:\inetpub\wwwroot\MyClient GOTO ERROR_DIR
XCOPY *.* c:\inetpub\wwwroot\MyClient /s /Y 1> nul 2> nul

Using the XmlDataSource Data property for easy samples
More Atlas stuff : Using the XmlDataSource Data property for easy samples: "Using the XmlDataSource Data property for easy samples
Here's a little trick to write samples that involves data binding controls to a database. It's very inconvenient to have to package a sample database with your code (especially when it's just a few lines of code in a blog), and just making sure your users have SQL Server installed is no small thing. All this just diverts the attention from what really matters: your sample code.
It's a little-known feature that XmlDataSource enables you to declaratively expose sample data to the page. Here's how it's done:

Asynchronous WebService calls – the truth behind the Begin… End… functions
After running into this same fundamental problem again (different calling behavior, but same pipelining idea), the behavior is different than I expected based on the documentation. I decided to do some more digging and resolve this once and for all.To illustrate, let’s take a simple WebService function exposed on a service called SimpleService:
public struct Bar { public int i; }
[WebMethod] public int Foo( Bar bar ) { System.Threading.Thread.Sleep(2000); return bar.i; }

The DR Refresh has just been released, it is the same location as before, you can get to it from the VS Zone:
http://www-128.ibm.com/developerworks/db2/zones/vstudio/
Please make sure you uninstall the current DR first - the refresh does not support installing overtop of an already installed DR.
This refresh will coexist with any level of V8, and includes a runtime client that can be installed seperately. It does not require V8 already installed on the machine.
This DR refresh will also work against the Viper test drive server, including the new XML datatype. This functionality should be considered more beta level code.

Stuart Celarier : Transact this! System.Transactions 2.0 tutorial: Part 8 — Enlisting a volatile resource manager in a transaction: "Transact this! System.Transactions 2.0 tutorial: Part 8 — Enlisting a volatile resource manager in a transaction
From the task list we wrote in Part 6, the next items are to change the value of the managed int in a transaction which commits, and in a transaction which aborts. This will require making the volatile resource manager aware of when an ambient transaction is present, and enlisting in it.
Testing a change in a committed transaction
Here’s the task before us.
Item 4. Change the value of a managed int in a transaction that commits.
Following the same process, we’ll create a unit test by first writing the code that the client is expected to write, and then asserting what the client should expect from that code. Then we’ll implement the bare minimum to get the test to pass.
Starting from where we left off, add a unit test to VolatileResourceManagerTest.cs [.vb] that changes the value of an int managed by a VolatileResourceManagerInt inside of a transaction that commits.
[Test]
public void VolatileResourceManagerIntCommit()
{
int i = 3;
int j = 4;
VolatileResourceManagerInt vrmi = new VolatileResourceManagerInt( i );
using ( TransactionScope scope = new TransactionScope() )
{
vrmi.Value = j;
scope.Complete();
}
}
The calling scope.Complete votes to commit the ambient transaction. Since nothing else is voting, the transaction will commit.
The client should expect that the VolatileResourceManagerInt has the correct value before and after assignment, and after the transaction. Here we�"

How to: Perform Custom Authentication Using SOAP Headers
How to: Perform Custom Authentication Using SOAP Headers: "How to: Perform Custom Authentication Using SOAP Headers
The following custom solution is built using ASP.NET to provide an authentication mechanism using SOAP headers. The solution involves a custom HTTP Module on the Web server that executes the following steps:
The HTTP Module parses HTTP messages to check whether they are SOAP messages.
If the HTTP Module detects a SOAP message, it reads the SOAP headers.
If the SOAP message has the SOAP header with authentication credentials, HTTP Module raises a custom global.asax event.
In the sample provided, the HTTP Module authenticates the user and sets Context properties that a Web service can use to decide whether the client is authorized access to the Web service."

System.Data.OracleClient requires Oracle client software version 8.1.7 or greater. on ASPNET 2
Roy Tore Gurskevik's weblog : System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.: "When usign System.Data.OracleClient with Oracle9i client, i got the following message while connecting to the Oracle database from and ASP.NET application.
System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
Cause
Security permissions were not properly set when the Oracle 9i Release 2 client was installed on Windows with NTFS. The result of this is that content of the ORACLE_HOME directory is not visible to Authenticated Users on the machine; this again causes an error while the System.Data.OracleClient is communicating with the Oracle Connectivity software from an ASP.NET using Authenticated User privileges.
Solution
To fix the problem you have to give the Authenticated Users group privilege to the Oracle Home directory.
Log on to Windwos as a user with Administrator privileges.
Start Window Explorer and navigate to the ORACLE_HOME folder.
Choose properties on the ORACLE_HOME folder.
Click the �Security� tab of the �Properties� window.
Click on �Authenticated Users� item in the �Name� list.
Uncheck the �Read and Execute� box in the �Permissions� list under the �Allow� column.
Re-check the �Read and Execute� box under the �Allow� column
Click the �Advanced� button and in the �Permission Entries� verify that �Authenticated Users� are listed with permission = �Read & Execute�, and Apply To = �This folder, subfolders and files�. If not, edit that line and make sure that �Apply To� drop-down box is set to �This folder, subfolders and files�. This should already be set properly but it is important that you verify it.

Brian Knight, SQL Server MVP : Pubs and Northwind databases not installed in SQL Server 2005: "Pubs and Northwind databases not installed in SQL Server 2005
I love the new Microsoft SQL Server 2005 sample databases (AdventureWorks and AdventureWorksDW). Compared with the Northwind and even worse the Pubs databases, they're amazingly more real-world. They show best practices and demostrate a good portion of the 2005 features. The problem lies in a lot of the SQL Server 2000 examples on the Internet still work in SQL Server 2005 and content that's specific to 2005 is still being produced. So, what to do while you wait for the examples to be updated? Why not live like it's 2002 and install the SQL Server 2000 sample databases? That way the sample RDL files, T-SQL scripts and most other examples on the net will work. "

Jeremy D. Miller -- The Shade Tree Developer : Test Driven Development with ASP.Net and the Model View Presenter Pattern
Jeremy D. Miller -- The Shade Tree Developer : Test Driven Development with ASP.Net and the Model View Presenter Pattern: "The traditional approach for building maintainable user interface code is to separate the typical concerns of a user interface with the Model View Controller (MVC) pattern. Unfortunately, ASP.Net is optimized for Rapid Application Development, not for creating maintainable code. A common criticism of the ASP.Net development model (and ASP classic before that) is that it does not enforce or even encourage a clean Model View Controller separation. Many ASP.Net applications seem to be a jumble of data access code, HTML markup, and business logic, but it doesn’t have to be that way. By itself, the “code-behind” model in ASP.Net does not do enough to create a good separation of concerns. Plus it’s difficult to get code-behind code into unit tests.
My preference is to use the Model View Presenter pattern to structure ASP.Net code to create maintainable and testable solutions. I think of MVP as just a flavor of MVC, but it’s worth stating the differences. The central fact of MVP architectures is that the “view” is a very shallow wrapper around the actual screen. Unlike most traditional MVC implementations, the view classes are entirely passive. The Presenter classes are the active classes that are responsible for initiating the view processing. "

ClickOnce security issues
ClickOnce security issues: "In particular, Dominick (in related posts) points to this article by Brian Noyes which indicates the following:
The registry key \HKLM\Software\Microsoft\.NETFramework\Security\TrustManager\PromptingLevel is the one that allows you to customize the prompting behavior. This key is not present by default after a .NET Framework 2.0 installation, so you will have to create it manually if you want to customize these settings.
Dominick has provided these changes in the lockdown registry script. If you are writing ClickOnce applications, be sure to read this post and understand the issues as well as use his suggestions for locking down your own deployment. "

Web Log : Using SQL Server Management Studio (and Profiler) Tools with SQL Express 'User Instances'
Stuart Padley's Web Log : Using SQL Server Management Studio (and Profiler) Tools with SQL Express 'User Instances': "In the SQL Server 2005 Express Edition, available for free here, there is new connection string option: 'user instance=true'. When this connection string option is specified, the SQL Express instance you are connecting to (we call this the parent instance), spins of another instance of the sqlservr.exe process, as a client process (not a server service), running in the security context of the currently logged on user. The connection object passed back to the client is to this new user instance (we also call this the 'child instance'), running as a client process in the user's security context.
Internally (in the SQL Engine Group), we call this feature RANU, 'Run As Normal User', it enables each user to have their own sqlservr.exe process, sandboxed to their own security context.
For troubleshootig purposes, it maybe useful to use your SQL Server Management Studio and/or SQL Server Profiler tools (obtained when purchasing a Workgroup/Standard/Enterprise edition) to connect to the 'user instance'."

Eric Wise : Self Documenting Code
Eric Wise : Self Documenting Code: "Methods
When you name a method, do try to describe its intent. Please don't use generic names like 'GetValue', or 'GetNext', or 'GetAvg'. They are obscure and require the reader to actually drill into the logic to determine what the method actually does. Instead use something like 'GetCustomerId()' or 'GetNextCustomer' or even 'CalculateAvgPrice'.
In addition, when naming methods, since they are 'actions' I try to use the verb-noun naming convention. A good example of this is 'DisplayHourlyReport', a bad example is 'HandleOutput'.
Another advantage to implementing this type of specific naming in your code is that it can give you an excellent heads up when a method is trying to do too much. Many coders, including myself, advocate that a method should be responsible for only one task, and related tasks even if called in line should be abstracted to their own methods. When you are attempting to name a method and you find it difficult because of the scope of the method you should definitely examine it and see if you can break it up into smaller more specific pieces.
Variables
Simliar to the principles for naming methods, name your variables explicitely as to what they accomplish. The worst case scenario of this would be using a variable 'd' which tells me absolutely nothing. Slightly less harsh would be using 'dt, dte, or date'. What is most beneficial to the reader is using a name like 'CurrentDate' or 'MeetingDate'.
Something many are guilty of, including myself, is the use of counters like i or j. This is mostly the fault of our coding book authors since it seems to be in almost any sample code that has a loop counter. However i and j tell us nothing about the loop. This also ties to the use of magic numbers in l"
Test Driven Development (TDD) and Extreme Programming (XP) Agile Methods at Google
Test Driven Development (TDD) and Extreme Programming (XP) Agile Methods at Google: "After reading Applying UML and Design Patterns - An Introduction to Object-Oriented Analysis and Design and Iterative Development by Craig Larman, I am now using a custom version of Agile UP as presented in the book. I say ?custom?, because I am still getting comfortable and knowlegable about various agile methods and trying to find what works for me. Given my love for test driven development, Extreme Programming may better suit my needs, but I will probably take what I need from several methodologies, which is okay.
Regardless, I think the key is iterative development. You want to develop your applications in short iterations ( 1 - 2 weeks for my projects ) that produce quality subsets of your application. For me, these iterations have to produce a compilable and executable subset of the application from which the client can provide feedback. I also agree with Craig Larman in that your initial iterations should focus on a combination of Risk Driven Development and Client Driven Development Requirements. Hit those requirements first that are architecturally significant and difficult as well as provide those features that are signficant to the client. If you wait on the tough stuff until the end, you are setting your project up for doom if it turns out you cannot pull off the critical functionality based on your earlier work. You risk the chance of an application core rewrite."

Enjoy Every Sandwich : SQL Server Express failed to generate user instance
Enjoy Every Sandwich :: "SQL Server - Otherwise (RSS)
Think of it as a default constraint
A fix for that annonying per-user instance problem with SQLExpress
Thanks to fellow DevelopMentor 'Brain' Kevin Jones (RSS) for pointing this one out.
These problems left me stranded for days, then today, on another machine, I hit a different set of problems I kept getting the following 'Failed to generate user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.' and if I set 'User Instance' to false the following 'An attempt to attach an auto-named database for file C:\[app_path]\ASPNetDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.'
..
If you don't want to follow the link, the short answer is that SQLExpress creates a directory per user in 'c:\Documents and Settings\[user]\Local Settings\Application Data\Microsoft\Microsoft SQL Server Data\SQLEXPRESS' that it uses to store information. Deleting this directory has fixed both of my problems. "

AJAX problems for newbies
AJAX problems for newbies: "AJAX problems for newbies
I have some items I learned about AJAX (or Ajax.NET Professional) developer newbies:
You cannot access the controls or HTML elements on your web site if you are using DOM/DHTML on the client-side to modify data. Without a postback you will not get the changed parts of the page. An example: if you have a placeholder control you can set the visibility style to hidden on the client. If you want to have the same value for the visibility value on the server you have to post it back, with AJAX or a full postback.
You should not do too many AJAX requests. One reason is that you can only have two connections at the same time (with one process, i.e. with one running iexplore.exe). If you want to initialize a lot of controls on window onload event you should pack it in one method. If you have some initializing data use the JSON serializer to write this data as a JavaScript to the page instead of invoking a AJAX request later.
The Session and Cache collections are available through the System.Web.HttpContext.Current static value. You can also implement the preferred way with implementing the IContextInitializer interface. This will be needed for future developments.
AJAX should not be used to get MBs of data back to the client. Also, you should have a look at the viewstate, some developers showed me pages that are filling DataSets from a database during Page_Load and again, if they are using AJAX. Decide what you want to use and load within AJAX or the common ASP.NET Page.

SmartNavigation removes CSS and the solution
Sanjay kattimani's blogspace: "Smartnavigation removes CSS after postback
This was the sole reason for blogging this. Yes smartNavigation strips off css after a postback.
Solution - you need to explicitly specify the path of css as absolute path instead of relative path. You can keep it dynamic by adding some server side code as below LINK href=''< =Request.ApplicationPath %>/Styles/Sanjay.css''
Microsoft's documentation of SmartNavigation
If you still wish to use smartnavigation on other browsers take a look at this code project (Free source) Crossbrowser SmartNavigation Alternative II
Conclusion: Use this feature only when you are sure of your audience using latest IE (at least IE 5) only. And make use of it when its absolutely necessary to make your application work better. And do take care of css paths etc."

After downloading fixes from Microsoft Windows Update page or via Automatic Updates, you may notice that Windows XP no longer logs into your account automatically. This is caused by the .NET Framework Update from Microsoft. It creates an additional user account called ASP.NET, which you can see in the Control Panel User Accounts applet. But, don't need to remove this update or don't delete this account. You can still configure Windows XP to automatically login using these methods:
