CodeProject: Binary Formats in JavaScript: Base64, Deflate, and UTF8
This article demonstrates using binary formats in JavaScript.

This article demonstrates the using of binary formats in JavaScript code. JavaScript, by its nature, cannot operate with binary data represented as a fragment of memory – as a byte array. That makes it difficult to use community developed algorithms and encodings. A good example is the DEFLATE compressed format. This raises more problems if the JavaScript code has to be run on a web browser: data has to be delivered over HTTP.
In the proposed implementation, a byte array is emulated by a regular JavaScript array of objects. Also, the given implementation tries to solve the problem of binary data transfer to a client-side script. Let’s assume we have DEFLATE compressed data (.NET’s System.IO.Compression namespace, Java’s java.util.zip.*, PHP’s http_deflate) and there is a way to transfer it to the client in BASE64 format.

CodeProject: Paging of Large Resultsets in ASP.NET

The paging of a large database resultset in Web applications is a well known problem. In short, you don't want all the results from your query to be displayed on a single Web page, so some sort of paged display is more appropriate. While it was not an easy task in the old ASP, the DataGrid control in the ASP.NET simplifies this to a few lines of code. So, the paging is easy in ASP.NET, but the default behavior of the DataGrid is that all resulting records from your query will be fetched from SQL server to the ASP.NET application. If your query returns a million records this will cause some serious performance issues (if you need convincing, try executing such a query in your web application and see the memory consumption of the aspnet_wp.exe in the task manager). That's why a custom paging solution is required where desired behavior is to fetch only the rows from the current page.
