Keep 'em coming! | | | | | DTDs and Markup Languages | | A DTD in an XML or HTML document provides a list of the elements, attributes, comments, notes, and entities contained in the document. It also indicates their relationship to one another within the document. In other words, a DTD is the grammar of an XML or HTML document. When using a DTD for an XML document (including XHTML), the DTD is there to provide structure for your documents. It is easy to write an XML document, but without the DTD it has no syntactic meaning to the computer. | | | | | How to Implement Java Comments | | Java comments are either explanations of the source code or descriptions of classes, interfaces, methods, and fields. This article deals with the former type which are known as implementation comments. They are usually a couple of lines written above or beside Java code to clarify what it does. | | | | | Checking Your Email with Ruby | | Checking your email with Ruby is as simple as using the pre-installed POP3 email libraries. POP3 is used to check your mailboxes on ISP mail accounts. It's one of the ways a number of popular email clients, like Outlook Express, Eudora and Thunderbird, check and download the email you have stored on your ISP's server. Though the IMAP protocol is often used too, especially on mobile devices and in corporate environments, most mail servers support the POP3 protocol. | | | | | What is Visual Basic? | | It's a computer programming system developed and owned by Microsoft. Visual Basic was originally created to make it easier to write programs for the Windows operating system. The basis of Visual Basic is an earlier programming language called BASIC that was invented by Dartmouth College professors John Kemeny and Thomas Kurtz. Visual Basic is often referred to using just its initials, VB. | | | | | | |  | You are receiving this newsletter because you subscribed to the About Programming newsletter.
