How Base64 Content Encoding Works

The term “Base64” refers to a specific MIME content-transfer encoding. It’s also used as a generic term for any similar encoding scheme that encodes binary data by treating it numerically and translating it into a base-64 representation.

Incrementing a C# Variable Efficiently

Calling JTidy from Java to Convert HTML to XHTML

The open source JTidy project does an excellent job of converting HTML files to the newer XHTML standard. The following code shows how to invoke JTidy programmatically from Java: /*In: C:Data_Localxmldocs est.htmlOut: C:Data_Localxmldocs estXHTML.xml*/import org.w3c.tidy.Tidy;import;import;import org.w3c.dom.Document;public class HTML_to_XHTML{ public static void main(String[] args){ try{ FileInputStream FIS=new FileInputStream(“C://Data_Local //xml//docs//test.html”);

Using the OneWay Web Service Attribute

When you call a web service method that doesn’t return a value (a void method), you don’t want to waste time waiting until the call returns. But by default, the calling thread blocks until the server responds. In such cases, you can use the OneWay Boolean attribute of the SoapDocumentMethod

Dances with Workflows (One Newbie’s Journey)

ecently I started working with a client who was interested in using Windows Workflow Foundation (WF) in a custom application. Having never used WF before, I thought it might be interesting to document the experience and my assumptions as I started learning and implementing the technology in production. I talked
