(Page 1 of 4 )
Upgrading Visual Basic 6.0 applications to .NET involves a good bit of automation thanks to an upgrade wizard. Even so, there are certain issues involved, and some applications might be better off left in VB 6. This article will take you step by step through an upgrade, explain the core issues, and help you decide which of your applications to upgrade.
Visual Basic 6.0 is a lightweight, robust and powerful development environment built for developers. With the release of Visual Basic .NET, developers gradually shifted their attention to .NET and hence there was a need to upgrade existing Visual Basic 6.0 applications. It is nearly impossible to convert an existing Visual Basic 6.0 application to Visual Basic .NET from scratch. It will involve a substantial amount of time and investment.
For the purpose of this article, I will make use of a free open source application which is named MetaCoder. I had initially developed this little application using Visual Basic 6.0. It will enable you to generate Meta codes for your web pages. I am currently working to port this application into .NET, and I will show you how to do this using Visual Basic .NET 2003 in a step-by-step manner. You can download MetaCoder right here.
In this article, I will examine the steps required to upgrade an existing Visual Basic 6.0 project using Visual Basic .NET 2003, and also provide some explanation of additional issues which you will commonly face during an upgrade. Visual Basic .NET ships with a cool tool called upgrade wizard. This wizard will perform all the required tasks associated with an application upgrade.
