With Microsoft. NET platform, Visual Basic is beginning to become a completely object-oriented language, referred to as vb.net. Although there have been some fundamental changes, the enthusiasm of developers from VB6 to vb.net is still quite high, even for experienced programmers. In this article, I'll list the changes in the Visual Basic language and illustrate them where appropriate. The list here may not be complete, but it already includes most of

A friend who designs a lot of TV must notice that many animated scenes are beautifully crafted, so can you design a similar scene with VB6, the answer is yes, the following code can slowly draw a random shape, you can set the density of tree trees, and can slowly in this tree "knot" A specified number of red "fruits"--very interesting.

Can VB6 handle structured exceptions. C ++ builder extends the processing of structured exceptions and supports the _ finally keyword to ensure that the routine has only one exit. It is a very scientific method to handle errors, it demonstrates the profound programming experience and wisdom of C ++ builder developers. VB. NET's imitation of it is the biggest praise for the handling of structural exceptions.See an example of VB. NET structured exceptio

In the work, you may encounter the need to migrate the code written in VB to VB. NET, there are a lot of details to deal. Fortunately, after so many years of Internet development, many questions have been answered on the Internet, so you can search for them to solve them. I have also encountered the migration from VB to VB. NET. Now I will summarize the problems encountered and their solutions or alternative methods to facilitate future users.

VB6 language basics After preparation, we can start programming. For the general application development process in Visual Basic 6, the interface is designed first, and then functional code is written. In the previous introduction, after creating a project (such as "Project 1"), a form Form1 is automatically created. In the example in this chapter, we will start to design this form. You can save this program while doing it, and we will continue to use
