Sometimes looking at past and what you did before makes you happy. Yesterday I was deleting some test projects from my Visual Studio 2003 projects folder and saw my old 3D XO (Tic-tac-toe) game. I wrote it in cloudy years (inspired from a famous novel by Ali Ashraf Darvishian ) in university when I had...

One of famous common easy techniques in Visual Basic casing structures which is familiar to most of Visual Basic developers is the ability to compare a value with several variables in Select Case statements. It has been pointed many times but as I saw the lack of this technique in someone’s code...

I recently received the following email message regarding a Podcast interview I did about 6 months ago: Hi Jackie, Hope all is well! We did an interview with you on VB6 to VB.NET migration back in the early part of this year for .NET Cast. I wanted to give you a short update - the Feb 14th episode "XML...

The latest Deitel book (I reviewed a couple of chapters and got a freebie) arrived today. Visual Basic 2005 for Programmers, Second Edition runs nearly 1300 pages and boasts dozens of Microsoft, industry, and academic reviewers. I'm a person who learns to program by hacking about at the keyboard, playing...

As you see , that team lists the precise issues they're working on for the service pack release. What a great idea! I don't work in C++, but it...

I wasn’t sure I was going to report a version of Y using Object rather than explicit recursive types, but it turned out to be so easy and pretty that I couldn’t resist.

Ok, we have almost everything on hand to write a clean and honest recursion-free factorial in VB, albeit with recursive types. I actually struggled with this for some time, the problem being that we have functions of Long to Long —call those of type df , then functions from df to df —call those of type...
