When you run Setup, you create a table of contents for Visual Basic, which allows you to select the VisualBasic part you want to install. In addition to the operating system files in the \os directory, other files on the CD are not compressed, so they can be used directly from the disk. For example, there are a number of tools and parts in the \tools directory that can be run or installed directly from the

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

These two data structures run through this book and are used to create more advanced data structures, such as the hash table introduced in chapter 5th. The 3rd Chapter: you will learn recursion, a practical technique that is used by many algorithms (such as the quick sort introduced in chapter

Visual Summary: This article explores the possibilities of using Visual Basic 6.0 in test automation and lists some examples that are applied in practical work Deficiencies of an existing automated testing tool At present, an obvious fact in front of software test automation is that the tools currently available do not do what we want them to do; it is unrea

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.

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
