(Integers are probably the first.) So there is a lot of useful string processing built into VB.NET. The Filter function is one and a new article here at About Visual Basic gives you a fast explanation showing how to use it.</p>...<p><a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://visualbasic.about.com/b/2012/08/19/filter-function-string-processing-in-vb-net.htm">Read Full Post</a></p> http://visualbasic.about.com/b/2012/08/19/filter-function-string-processing-in-vb-net.htm Sun, 19 Aug 2012 09:41:55 +0000 2012-08-19T09:41:55Z http://visualbasic.about.com/b/2012/08/12/257773.htm <p>Although you will find these terms mentioned in technical articles, you won't find any methods with these names. In fact, "Shallow Copy" is the only type of copying directly supported by a method and that one is named MemberwiseClone. (Where Microsoft got that name, I do not know. If you think you can explain it, let the rest of us know.)</p>...<p><a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://visualbasic.about.com/b/2012/08/12/257773.htm">Read Full Post</a></p> http://visualbasic.about.com/b/2012/08/12/257773.htm Sun, 12 Aug 2012 19:27:04 +0000 2012-08-12T19:27:04Z http://visualbasic.about.com/b/2012/08/04/does-this-microsoft-example-make-sense-to-you.htm <p>Check out the example at <a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://msdn.microsoft.com/en-us/library/system.string.clone(v=vs.100).aspx">Microsoft's page about the String.Clone Method</a>.

Design Patterns, on the other hand, are all about the why and how of programming, not the syntax. This article, one of a series about design patterns in VB.NET, discusses what might be the most popular design pattern, the Singleton pattern.</p>...<p><a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://visualbasic.about.com/b/2012/07/14/design-patterns.htm">Read Full Post</a></p> http://visualbasic.about.com/b/2012/07/14/design-patterns.htm Sat, 14 Jul 2012 14:25:22 +0000 2012-07-14T14:25:22Z http://visualbasic.about.com/b/2012/07/08/using-timespan-and-datetime.htm <p>A companion article here at About Visual Basic, <a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://visualbasic.about.com/od/usingvbnet/a/ticktimer01.htm">Of Ticks and Timers</a> describes the fundamental basis of DateTime and TimeSpan from the point of view of the Ticks that they're made of.

The rap is that you need the ability of a class to inherit from more than one parent to be able to do things like dynamic binding and polymorphism.</p>...<p><a href="http://clk.about.com/?zi=1/1hc&#038;zu=http://visualbasic.about.com/b/2012/06/23/multiple-interfaces.htm">Read Full Post</a></p> http://visualbasic.about.com/b/2012/06/23/multiple-interfaces.htm Sat, 23 Jun 2012 22:05:05 +0000 2012-06-23T22:05:05Z
