String Combinatorics with Visual Basic.NET

Wed, 21 Jun 2006 14:00:00 EDT

Sooner or later you'll probably find it useful to be able to create and manipulate combinations programmatically. By far the most useful kinds of combinations are string combinations. A string combination of order (n, k) is a subset of k strings chosen from a set of n strings, where order doesn't matter.

Converting VB6 to VB.NET, Part I

Thu, 26 May 2005 09:00:00 EDT

If you're one of the many who have VB6 code, you have three basic options: stay with VB6, convert to .NET, or rewrite from scratch. In this article, we will look at converting VB6 code to VB.NET and C#. I'll discuss when it makes sense to convert versus staying with VB6 or rewriting from scratch. I will cover what converts well and what does not, different ways to do the conversion, how to get code ready to convert, and handling issues after the conversion.

Converting VB6 to VB.NET, part 3

Wed, 12 Jan 2005 00:00:00 EST

This is the third and final installment in a three-part series. In the first installment (.NETDJ, Vol. 2, issue 9), I covered general conversion issues, in the second installment (Vol. 2, issue 10), I finished general conversion issues, and covered issues associated with database conversions. In this final installment, I will cover ASP Web page conversions, converting to VB.Net 2005, converting to C#, and finally, I will cover some arguments for converting.

Does Java Patents Case Affect Microsoft Too?

Hewlett-Packard, IBM, and Microsoft are all licensees of the same patents that Kodak is successfully suing Sun Microsystems for infringing, the Eastman Kodak Co. revealed yesterday.

Converting VB6 to VB.NET, Part II

Mon, 04 Oct 2004 00:00:00 EDT

Last month (Vol. 2, issue 9), I gave an executive overview of the conversion process, and started looking at converting general VB6 code to VB.NET. This month I will finish general conversions, including DLLs, then start on database conversions. Next month, in the final segment, I will cover converting ASP.NET Web pages, and look at converting to VB.NET 2005 and C#.

.NET Makeover

Mon, 13 Sep 2004 00:00:00 EDT

As developers in the 1990s, we became accustomed to migrating applications from one version of VB to the next. We expected Microsoft to continually provide new VB releases that addressed feedback from the developer community (also known as 'identified bugs'), made VB software developers more productive, and took another step toward 'true' object-oriented (OO) programming. While Active Server Pages (and VBScript) provided a foothold into Web development, they also represented a step backward in the path to building OO systems.

Using Features of Visual Basic .NET to Trace Your Application

Mon, 13 Sep 2004 00:00:00 EDT

At one time or another, most applications have to determine when a certain subroutine or function is executed and inform the user when an important event or an error occurred. Over the years, clever developers created different methods for these kinds of notifications. At some point in time, just about every Visual Basic programmer has tried using a message box to show when a method or subroutine was called. While this technique might work well for debugging, it's highly error-prone. Because there are legitimate times when a message box should be shown to the user, the developer can't just comment out every call to MessageBox.
