In addition, developers will be able to create highly scalable, threading code with clear free threads, as well as to incorporate modern language constructs such as highly maintainable code for structured exception handling. Visual Basic will provide all the language features that developers need to create robust, scalable, distrib

In addition, developers can write highly scalable code through explicit free threads, and write highly maintainability code through other modern language concepts such as structured exception handling.

real threat to traditional VB. Does VB. NET surpass Windows platforms? Interestingly, some advances in the Java camp seem to have an impact on Visual Basic programming. Microsoft has failed to make full use of the cross-platform version of the language. This means that Sun's Java will lead the cross-platform field because of its ability to run on any platform, which will bring practical commercial bene

Relatively speaking, the use of events is relatively simple. Before use, we must first define the event, which means to notify Visual Basic of what events are called. An event may have its own parameters. For example, a command button has a click event, which has no parameters. In addition, the text editing box has a keypress event, which processes related content using a value named "keyascii. Defining an

Starting from the basic concepts and syntax, learning a language, especially now is a visual development, but I suggest not to drag several widgets first, instead, you must first understand the concepts, syntaxes, and specifications of the language. Although VB. Net is very similar to the previous VB6 syntax, the current VB. Net is a brand new object-oriented language, so there are some differences between

At the end of the second part of this tutorial, we encountered a small problem, but it is actually a big problem. If we have time, this problem should be worth our effort. Remember how we encountered that problem? At that time, we first compiled ActiveX DLL and then compiled the test program using the DLL. Next, we re-compile the DLL, Which is because the content in the DLL needs to be modified. However, an error occurs when you run the test program again!Although, we can re-compile the test pr
