The JavaScript CompressorRater

The JavaScript CompressorRater compares several popular tools used for compressing JavaScript. At the moment, it compares JSMin, Dojo shrinksafe, Packer and the YUI Compressor (which has been recently been released and has very good results so far). Dojo shrinksafe and YUI Compressor require Java and Rhino installing. Packer can be run online and JSMin is a command line tool (with code available in several languages for use within your own applications).

Before using any of these tools, it is best to check your syntax is correct (adding the optional semi-colons and checking the code with JSLint).

You can see the results of the compression with several popular JavaScript libraries: jQuery, Prototype, YUI and Scriptaculous. Mootools and Dojo are missing from the comparison. Rather than using one tool to compress your code, it may be better to try several and use the one that gives you the best results.

Basic Excel Spreadsheet Generation (ASP/ASP.NET)

The 'correct' way to generate Excel spreadsheets is through the use of Office Web Components . However, due to the licensing (see MSKB Article ) you cannot use them on a public internet site (as a client license for Office is needed for each user retrieving the document). However, this can be overcome due to the fact that Excel recognises HTML code. You can therefore output HTML that can be opened in Excel: First of all, set the content type and response header to make the browser handle it as an Excel spreadsheet. ASP VBScript: <%@Language="VBScript"%> <% Response.ContentType="application/vnd.ms-excel" Response.AddHeader "content-disposition", "attachment; filename=ExcelFileName" %> ASP JScript: <%@Language="JScript"%> <% Response.ContentType="application/vnd.ms-excel"; Response.AddHeader("content-disposition", "attachment; filename=ExcelFileName"); %

The HTML Agility Pack is an HTML parser for .NET, supporting XPATH and XSLT parsing. Basically the HTML equivalent of XmlDocument . Example use (from site): HtmlDocument doc = new HtmlDocument(); doc.Load("file.htm"); foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href]") { HtmlAttribute att = link["href"]; att.Value = FixLink(att); } doc.Save("file.htm");
