Specifically, VB6 cannot implement class inheritance in the true sense (for example, inheritance in C ++), but implements also provides similar functions. We first create a class module cbase. CLs The Code is as follows: Private mvarbaseproperty as string Public sub basefunction () Msgbox "Hello world !" End sub Public property let baseproperty (byval vdata as string) Mvarbaseproperty = vdata End Property Public property get baseproperty () as stri

A review of the changes from VB6 to vb.net When creating a asp.net page, you need to use a compatible one. NET programming language, such as C #, VB. NET or JScript.NET. But there are many important changes from Vb6/vbscript to vb.net, which is the content of this article. Also, if you want to get more information about it, I strongly recommend that you read Mi

: If X=y Then Dim Z As Integer ' Other code End If Z=100 ' Outside of If ... Then Block The above code works very well in VB6 because it does not have a module-level variable scope. Module-level variables occur in other advanced programming languages, such as C + +. Variables defined in the Declaration module, as in the If ... The variables defined in the then module will fall out of scope when the decl

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.

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. (i) Programming principles We can draw "tree trunks and branches" on the

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 progra

Fortunately, we can use COM components to maximize the functionality of the ASP. You know, anything that can be written in a language such as VB,VC and VJ and other programming languages can be applied to the development of your Web site, which is COM (Component Object model).
