Today I realized that I miss those Visual Basic/Visual C++ type operators. You know the ones: Left, Mid, Right. I'm so used to using them, that I decided to override the string class. Simple enough, right? I just inherit from the System.String and then I get all the nice string methods, plus my own: Left, Mid, and Right. The problem, though, is that the System.String class is sealed. You can't inherit from it. So now what? Must I give up the dream of using those fine old methods?... |

Arguably, the reason that Java has become so popular as a programming language is because of the way it has abstracted away the difficulties in performing input/output and networking operations. C# has taken the same approach and has provided libraries that hide these complications. The previous two articles in this series have focused around the different language structures that a Java programmer needs to know to build simple C# programs; this article is going to focus on a few C# namespaces d... |

The clipboard is where your data is stored when you copy or cut some text or an image or a file or a folder. The clipboard is common across processes, which means we can use the clipboard as a mechanism to transfer data between two processes. Win32 gave us a Clipboard API with functions like OpenClipboard and GetClipboardData which most of you might be familiar with. In .NET Microsoft has encapsulated the functionality of most of these functions into some classes. The most prominent of these cla... |

If you want to write more portable code, using structured exception handling in a C++ program is not recommended. However, you may sometimes want to mix C and C++ source code, and need some facility for handling both kinds of exceptions. Because a structured exception handler has no concept of objects or typed exceptions, it cannot handle exceptions thrown by C++ code; however, C++ catch handlers can handle C exceptions. As such, C++ exception handling syntax (try, throw, catch) is not acce..... |
