This article is intended to help developers choose between a class and a structure when writing an application. You can review the basic points of comparison between the two types in the "Structures and Classes" topic of the Visual Studio .NET product documentation. To find this topic, start Visual Studio .NET, select Index from the Help menu, and type "structures, Visual Basic" in the "Look for" field.... |

Glad you asked! A logical operator is an operator that compares the truth value of two statements (one to its right and one to its left, like: Expr1 AND Expr2), and, depending upon the truth value of these two statements, returns true or false. While that may sound confusing, once we look at an example I think things will clear up a bit!... |

This article demonstrates how to access information about disk drives attached to a web server supporting ASP.
The techniques described here could have many uses, such as:
* Making sure a server supporting uploading of files has sufficient disk space available before large files are uploaded.
* Creating an ASP document that will allow remote monitoring of disk space while the server administrator is out of town.... |

Considering I program in Microsoft® Visual Basic®, this shouldn't come as a big surprise, but I just love it when software supports some form of extensibility model. Call them add-ins in Microsoft® Office, or plug-ins in Adobe Photoshop® and Microsoft® Windows Media® Player, it is all the same to me. All of these terms indicate some way that I can add my own little bit of functionality to an already existing piece of software.
Now, as I said in my first column, I often write complete applicat... |

Here's what I've learned: If you sit in the front row on an airplane, you'd better not do something you don't want everyone on the plane to see. Last summer, I took a trip from Los Angeles to Washington DC. A long ride. I had purposefully requested the bulkhead row at the front of the coach section (didn't get upgraded on this one) so I could get some work done. Because of the never-ending weight-loss cult by which I've been brainwashed, I drink a lot of water. I have clean insides. This also me... |

When we implement an application using remoting, we'll have three key components to the application: the Client (the application calling the server); the Server Library (the DLL containing the objects to be called by the client); and the Host (the application running on the server that hosts remoting and the Server Library).
Basically, we create our server-side objects in a Visual Basic .NET Class Library project. Then, we expose the classes in that DLL from our server-side remoting host appl... |

Do loop is the most versatile of all of the loop constructs. This is because you can easily make it loop as many times as you like based on any criteria you like. (However, you'd have to go through some trouble to use it to traverse a collection — For Each…Next is much better for that.) The power of the Do loop is in the use of the While and Until keywords. You can use While or Until at either the beginning of the loop or the end of the loop to control whether the loop will go around again. Let'... |

For my last project, I had a requirement where I can use PropertyGrid control. I tried to get information on that, from Microsoft and searching all over Internet, newsgroups, but I could find only a couple of articles from Microsoft. That's it, surprising, and not even a single example in VB.NET that compiles without errors and explains all in and outs of PropertyGrid control.
So, I decided to put all the information I collected, with fully functional working examples in VB.NET (which is my f... |

The code for this Windows application is so compact, it is presented here inline. Belying its small size, however, the app actually solves a real-world problem, namely the need to measure events of a few minutes' duration to about a half-second granularity. How long does Photoshop take to launch? How long have I been on the phone? "I'll bring your stapler back in five minutes." Yeah, right.... |

In VB.Net/c# we can generate emails and send them to the relevant people. Why can’t a sales manager receive an email with the daily statistics of their field agents? How about sending an email to the mobile users and have them receive the message right from within their business application. Customers could get an invoice emailed to them right at the point of sale and not sometime later.The problem is to allow our eVB or VB.NET/C# applications to generate these emails.
