Two, I have decided to upgrade the Crystal Report of my web application to the new version which was released before 10 days (last version of Crystal Report for Visual Studio 2010) , because whenever I open my Visual Studio 2010 web application it keeps asking me if I want to upgrade to the new version or not of the Crystal Report and he just said "you are using old version which is "10.0..." ", so each time he asks me I ignored and tell hem keep the current version.

So, I decided to upgraded today and say "Yes" I want to upgrade.
Anyhow, I have finished everything (compiling, and deploying the web site to the server), The development PC "Which is my PC 'Windows XP' " was the crystal Report working fine.
So I test to run the one that I have uploaded in the Production Server in a separate Virtual Directory because I don't' want to touch the live one, then whenever I tried to see the report of the crystal report but It failed and gave me message "Database Login failed".

The solution for that as below:

This problem is the same problem of running two version of asp.net framework, so it's solution will be like the old one which is to put each version of the crystal report of your web site in a separate Application Pool of the IIS.

Hope this solved problem of many users facing this problem.

If you are looking to enhance your web application using AJAX to provide a more fluid user experience, but you don't know where to start, you might want to start here... using code-behind page methods right in your client script.

One of the most powerful features of ASP.NET AJAX is its ability to tie back-end code to the users' browser in the form of JavaScript with the communication all behind the scenes. Although ASP.NET AJAX can interface with web services so well, you may not have the need or even want to create a web service to do some basic functionality; you may just want to use a method in your page class.

This article is going to discuss a 'real world' scenario where you might use ASP.NET AJAX to call methods on your page. The scenario is that of a "contact us" page. Most contact us pages follow a similar format: 1) display a form for the user to fill out, 2) validate that form against whatever requirements you might have and 3) display a "thank you" message to the user letting them know that you have received the message.
