In one of the previous articles we saw that we can use the web.config file to save our connection string. We also talked about the advantages which comes down to easily altering the connection string if it changes in the future. What we did not talked about was encrypting connection string. When we store the connection string in the web.config file it's stored in a readable form. If anyone can open the web.config file he can read the connection string and security will be jeopardize....

Often you need to pass variable content between your html pages or aspx webforms in context of Asp.Net. For example in first page you collect information about your client, her name and last name and use this information in your second page.
For passing variables content between pages ASP.NET gives us several choices. One choice is using QueryString property of Request Object. When surfing internet you should have seen weird internet address such as one below.
http://www.localhost....

There are many ways to do connection strings in asp. ASP+ presents a new frontier to perform connection strings. Many of the quickstart demos have the connection string listed in every page. This is ok for demo purposes, BUT what if you want to change your password. The only way is touch every page, NO WAY!...

You want to determine if your site has been visited by the IP address 231.34.124.3. How can you quickly figure out if the string "231.34.124.3" is in the array?...

This article will demonstrate how you can use StringBuilder, StringCollection and StringDictionary objects to work efficiently with Strings. Strings are the most heavily used things in software programming especially in ASP.NET web development. Because the HTML page that is rendered in the client side web browser is basically text as string type so you will need to work with strings a lot. There is an object of type String that represents a string in the .NET Framework and contains many useful m...

You may have noticed that the Replace method of the String and StringBuilder classes are case-sensitive methods. However, VB.NET supplies a Replace method which you could use in VB.NET and wrap in a class to use in other languages. That would be too easy though. :) Here are a few ways to implement case-insenstive replaces. Code #1 provides a case-insensitive replace function. Code #2 is sample ASPX page. Select the version you would like to see in the select list....

For years, classic ASP developers implemented page authentication by inserting some generic code at the top of each page that would grab user credentials, attach a cookie, and redirect. All that repetitive code was swept away by the ASP.NET HTTP modules for authentication. As a result, ASP.NET applications don't have to link each and every page being secured to the authentication module of choice. Everything can be done declaratively through the web.config file and a bunch of external resources,...

This article gives you a general view of the Encryption of Connection string inside the Web.config feature and
how you can use encryption and increase the security and keep the secure connection with the database. The .NET Framework 2.0 allows you to encrypt configuration sections within the Web.config or machine.config files. Encryption support for configuration files is added to the .NET Framework 2.0. The .NET Framework libraries
support for encryption and decryption in code. In this ar...

Using query strings to send data from the browser to the server is a widespread approach. Giving the visitor of a web application the oportunity of modifying them by transmitting them in clear text, is certainly a potential security threat. Thus, I encourage developers to encode query strings, even if they do not contain confidential data. However, I am aware that it is still possible to alternate an encoded query string, but with an appropriate exception handling this is harmless....

While I was writing this article, I saw that a fellow CP'ian, Ivo Beltchev, has already posted a typesafe string format library. The method I used in my library is quite similar to his. But my library is much simpler, and uses std::basic_string and C string functions to do the job instead of rolling out my own string routines, and doesn't use the Win32 API, but it doesn't support locale....

Query strings are a very convenient way of passing information to a new window or to a following page. The problem with query strings is that the information is visible. In my experience, the wiseass users see the query strings in the browser and try to duplicate the functionality: like "Oh, when I click the button, I get 'DeleteInventory.aspx?item=123&user=george&id=99' so, if I want to delete the item #222, I just need to use 'DeleteInventory.aspx?item=222&user=george&id=99' right?" Wrong, the...

This is an in-depth, behind-the-scenes look at strings in the Common Language Runtime and the .NET Framework. This study provides detailed information of the implementation of strings, describes efficient and inefficient ways of using strings.
I plan on developing a series of articles, exploring the underlying implementations of various fundamental features in C# and the framework, of which this is the first article, if The Code Project community finds this information helpful and offers ...
