Your code is ripe for SQL injection attacks. Define 'doesn't work'. What does it do ? Can you pinpoint the bit that doesn't work ? No-one is going to read all of this...

I just want to know that I have already a web application. I want to use ajax in one of my web forms.
I installed AJAX in my machine. Now to use ajax in my web application should I create a new web site in VS 2005 and select ASP.Net AJAX - Enabled Site
and then copy my all the web forms and datasets from my existing web application to this new AJAX application to be able to use AJAX.
I am wondering if there is any other way to use AJAX in already existing web application.

You cannot modify a collection and enumerate it at the same time. In other words, if you are counting a stack of coins, and someone takes some coins from the counted stack, you have to start your count again.
You can do the following to solve your problem:
1. Search for all the AplicacionID's in one table that don't belong in the other table.
2. Extract the AplicacionID from each row found and place it in an AplicationID collection.
3. Enumerate through the AplicacionID collection, search for the AplicationID in the target table, and, if the AplicacionID is found, delete the row or rows.
I converted a VS 2003 project to VS 2005. It works perfectly alright in VS 2003 but when I try running in VS 2005 I got strange thing going on. The code (my button click event ) runs twice? Has any one run into this kind of situation before please help. Am I missing some thing here? or do I need to set an option here?
Is 'AutoEventWireup' set to 'true' on your web page?
If so, then any event handling methods starting with "Page_..." don't need to be wired up. In VB, they don't need to the 'Handles' clause or an AddHandler statement and in C# you don't need the "+=" event wireup.
Alternatively, you could just set 'AutoEventWireup' to 'false'.

I have an application where on a lot of my ASP.NET pages i need to add text boxes which collect First Name, last Name, Age, Company Name etc and has a button which when clicked enters the above mentioned data into the database.It needs to be entered to the same database table all the time.No, I cannot use session info. I wanna know if it is possible to create a custom web control which does this? So I can add it to my tool box and drag and drop onto my pages as and when I need it. I havent seen instances where you can create a control which does db operation. I know you can use User controls(.ascx) but that way, it needs to be included in every project and every one can see the code and know whatz happening behind it. Help is appreciated. Samples are appreciated even more!!!
i am problem with loading images in Firefox using asp.net .images in the simple
image control are not getting displayed and listview with Images are displaying error but in IE6 every thing is working very fine;)
Wow, I can't beleive what I have been missing. I just recently found that if I drag my css file to my header section (or create a link to the css file), I can set all my style settings via cssClass property and the design view looks like how the page will be rendered.
Previously I was using skins and a .css file in the themes folder. However, when I put the style information in the Theme folder it was not applied in design view.
What gives? Is there no way to have a theme applied in design view, or am I just better off doing it the old school way with just a link to the .css file?
If you set the Theme in the Page directive or in the appropriate section of web.config, it should display just fine. However if you set the Theme from code (Page.Theme = "Theme1"), then the design view will be not available to show it.
Sidenote: sadly the VS2005 designer is not capable of rendering complex layouts achieved with divs and CSS, so it is better not to rely on it. Use "View page in browser" option instead.
