Since you almost don't need to write any code at all, these controls works fine for doing quick solutions with non-complicated data, (like fetching data from one table).
But when it comes to more complicated data structures it becomes more difficult to maintain these controls.
In these situations it is recommended to have more control, by knowing what is going on under the hood. This is where the Repeater control comes in handy.
In the following six upcoming posts I will show you how to use the Repeater control to establish almost the same things as you can do with the out-of-box controls plus a little more.
Here are the following parts that will be described:
1. Simple Repeater
2. Add, edit and delete Repeater
3. Multi-Row update Repeater
4. Sorting Repeater
5. Paging Repeater
6. All-In-One Repeater
In the next post we will go through the Simple Repeater.

In this small example we have an aspx page that has its valiateRequest turned off:
With the following desing:
If we type in a java script block and presses "Unsafe submit" button, the script will execute.
To prevent the injected script from running we can use Server.HtmlEncode() as follows :
Now when pressing button "Safe submit" the script will be encoded to html and will be unharm for the user:

In this post I am going to show how you in an easy way can select top, bottom and in between rows from a table. The table that I am using is a fictitious Customer table with primary key name CustomerID.
1. Selecting the first 10 rows from Customer table:
SELECT TOP 10 * FROM Customer ORDER BY CustomerID
The code above is quite straight forward using the "TOP" keyword to picking out the first 10 rows.
2. Selecting the bottom 10 rows from Customer table:
SELECT TOP 10 * FROM Customer ORDER BY CustomerID DESC
In this code we also use the "TOP" keyword but now we change the sort order to "DESC" (descenging) letting us picking out the 10 rows from the bottom.
3. Selecting rows between 10-20 from Customer table:
SELECT TOP 10 * FROM Customer WHERE CustomerID IN
SELECT TOP 20 CustomerID FROM Customer ORDER BY CustomerID
) ORDER BY CustomerID DESC
In the code above we use nestled query to achieve the extraction of row 10-20. The inner query picks out row 0-20 and the outer query picks out row 10-20 from the inner query.

In this article I will describe how to configure and use sessions by saving them to an SQL Server database.
1. Open a command prompt.
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727. (Note! This is however not recommended.)

In this article I descibe how you can reset the INSP Service message that pops up in the speedometer display every time you switch on the ignition. (Note! It only works on VW Passat/Audio A4 of model 1996-1999):
1. Press and hold the button that is below your speedometer (right button), at the same time switch the ignition on.
2. The message OIL Service should appear.
3. Release the right button (below speedometer).
4. Press the right button again and the message INSP will appear.
5. Release the right button (below speedometer).
6. Turn the left button (below the tachometer) to the right. INSP message will disappear.
7. Switch the ignition off.
Try switching the ignition on again. Now the INSP Service message should have disappeared.

Fixing iPhone - Could not activate cellular data network. You are not subscribed to a cellular data service.
But I had some problems when trying to access internet through my 3G sim card (with WLAN disabled). I kept getting the message:
Could not activate cellular data network. You are not subscribed to a cellular data service.
After a couple of tries I found the solution as follows:
1. Click on Settings --> General --> Network --> Cellular Data Network.
2. Under APN type in your provider, in my case I typed in:
3. After doing this I was able to access Internet without any error messages.

In this part I will describe how to create a bootable usb 'light windows' a.k.a Bart PE.
1. For this you will need an usb flash stick. I myself tried a No name usb 2GB and it worked fine.
2. You will also need the following files:
-pebuilder3110a (official site download)
-Windows 2003 Server SP1 or srsp1 (two extracted files from the win 2003 sp1)
1. Save the files from above to a place on your disk for example C:\
2. Extract the pebuilder3110a.zip to the folder c:\pebuilder3110a
3. In folder c:\pebuilder3110a create a new folder named: srsp1 (this will be used later)
4. Open a command-prompt and type in the following command to extract the files of Windows
5. A message box will appear asking you to select a directory for extraction, choose:
6. Copy the file setupldr.bin
7. Expand and copy ramdisk.sys by running the command:
expand -r C:\win2003sp1\i386\ramdisk.sy_ C:\pebuilder3110a\srsp1
8. Go to the folder: C:\pebuilder3110a Start BartPE by double clicking pebuilder.exe
9. A windows will appear. Select source to your windows xp cd (in my case F: was my cd letter):
10. If your Windows XP cd has Service Pack 2 included then you need to enable a plugin.
Click on the Plugins button and enable "RpcSS needs to launch DComLaunch Service First - SP2 only" in the list.
11. Click close when done.
12. Click Build, to start building the image that will be used for your usb.
13. If asked to create directory, click Yes.
14. Click Close when done.
15. Plug in your usb stick if you haven't already done that.
16.After building is finished go to command-prompt and type in:
pe2usb -f G: (where G: is my usb drive letter)
17. Type in YES when asked to. This will start creation of your bootable usb stick.
18. When done close the command-prompt window and take out your usb stick. You should now be able to boot from your usb stick.
This concludes the final part, Part 3 - Create a bootable usb 'light windows' a.k.a Bart PE.
By this I have now described three ways of using a usb flash stick booting. I hope you have had good use of this reading.
