In last month’s piece, objects came under the microscope, and in particular we looked at the “axis” of commonality/variability analysis that inheritance offers us. While inheritance isn’t the only form of commonality/variability available within a modern object-oriented (OO) language such as C# or Visual Basic, it certainly stands at the center of the OO paradigm. And, as also discussed, it doesn’t always provide the best solution to all problems.... |

One of the first things I tend to write whenever I try something new in a programming language, are console test applications. These test applications tend to start turning into complete test harnesses - quickly start outgrowing the original functionality. Typically they also start handling all of the special cases that I uncover as I develop.... |

First of all, if you are thinking Outlook Express, just forget it. The only three ways of integrating with Outlook Express are (and this is just my guessing) by paying Microsoft a lot of money and by giving them a really good reason to why you want to do that, or by hooking in through the encryption-entry, or by creating a proper hook and hacking your way in there. I've done the hacking (due to missing funds) and it's not a pretty sight, it works but it's everything from clean.... |

This article describes how to add variable replacements into your snippet generated code, or even a simple copy and paste function. The first thing we need to do is trap the code changed event from the IDE, we need to have a mechanism that allows us to look up a value to replace. Now we need to replace the inserted code. This will also allow us to use the functionality as an inline variable replacement, like word uses auto-correct. Secondly, we need this mechanism to work in conjunction with the... |

One of the fundamental ideas behind COM is that of binary compatibility. According to Microsoft, a client written in any language can use a COM component. This is sort of true. What is left to discover is that some client environments require more "support" from the component. Clients fall into roughly 2 camps of unequal capability. The first camp is exemplified by languages like C++, and (later by) VB. These languages are perfectly aware of QueryInterface (QI) and can generally access any in... |

This step-by-step article describes how to handle Excel events from an Automation client that is developed with Visual C# .NET. Visual C# .NET uses delegates to handle Component Object Model (COM) events. Delegates are a new concept in Visual Studio .NET.

You may want to display, or embed, an Office document directly on a Visual C# .NET Form. Visual C# .NET does not provide an OLE control that allows you to embed an Office document on a form. If you want to embed an existing document and open it as an in-place ActiveX document object within a Visual C# .NET form, a potential solution for you is to use the Microsoft WebBrowser control. This article demonstrates how to browse to an existing Office document and display it inside a Visual C# .NET for... |
