Now, lets get down to learning a few basic rules about writing the VB program code. First of all, let me say that though VB is very much similar to VB6 in terms of Interface and program structure, their underlying concepts are quite different. In order to qualify as a fully object oriented programming language, it must have three core technologies namely encapsulation, inheritance and polymorphism.
These three terms are explained below: Encapsulation Encapsulation refers to the creation of self-contained modules that bind processing functions to the data. These user-defined data types are called classes. Each class contains data as well as a set of methods which manipulate the data. The data components of a class are called instance variables and one instance of a class is an object. For example, in a library system, a class could be member, and John and Sharon could be two instances two objects of the library class.
Below is a list of all our latest articles you should be able to find just about any VB 6. Also please use the links on the left to browse our different sections or the search in the upper right corner of this page to find something specific.
It teaches you how to create a multi-page document, with page headers, footers, page numbers, shapes, and images. In the previous tutorial we looked out how to create a simple PDF document that was one page and was only text.
If you've seen many PDF documents on the web or elsewhere you know that they usually include more than just text. Fortunately we are able to do these things as well. Many times people have to purchase controls to do it for them. Not with this Visual Basic tutorial. This is the first in a series of tutorials.
It covers the creation of a basic PDF document. NET developers.
One of the biggest examples of this is the Visual Basic Power Pack that was released in Check out how to make use of it in your next. NET app. Level: VB. NET Input Box Sometimes you want to simply get the user's attention and let them know some information.
This is easy with the MessageBox. However, what if you not only want to get their attention but you also want them to input some information? Have no fear this article will show you exactly how to get that same functionality. Level: Writing To Text Files Once you start developing even the most basic of desktop applications you will hit a point where you need to save data out to a file. The simplest way to do this is to simply save it out into a text file if you want to get more advanced you can encrypt it.
This tutorial gives you the understanding you need to save data out into a simple text format. Level: Reading Text Files So you have a file full of text how can you parse and read it. This File Reading VB. NET tutorial explains exactly how. It goes over examples of fixed width files, tab and comma delimited files, and even how to use the. After going through these examples you will be handling text files with the best of them.
This is means as a developer we should be learning what all the Win32 API offers so that we aren't limited by the language or libraries we are using.
Level: Simple and advanced Conditional Experssions Comparisons in programming allow us to do the most simple and powerful thing - make a choice. By using comparisons we can do things like branch in different directions if something is true, or loop over a bunch of things until a comparison is false, etc. This tutorial explains all the operations VB. NET supports when doing comparisons. This will provide a solid foundation for some of the more advanced features of Visual Basic.
Yes, yes there is, and it is called join. Delimiter is an optional parameter that indicates what you want to place between elements are added to the string. By default this parameter is set to "".
Multidimensional arrays can be thought of as arrays-of-arrays. For example, to visualize a two dimensional array we could picture a row of CD racks. To make things easier, we can imagine that each CD rack could be for a different artist. Like the CDs, the racks would be identifiable by number.
Below we'll define a two dimensional array representing a row of CD racks.
The strings inside of the array will represent album titles. You could also add a third dimension if you wanted. Keeping with our CD rack analogy, you could picture this third dimension as a hallway with several rooms. Inside of each room would be a row of CDs racks. If you wanted your hallways to have 10 rooms, each with CD racks like the ones in the above example, you could declare your array as follows: Dim cdRackHallway 0 to 9, 0 to 1, 0 to 3 As String In Visual Basic 6.
In Visual Basic. NET, the maximum number of dimensions an array can have is Most arrays you will need to deal with will only be one or two dimensions. Multidimensional arrays can require a decent amount of memory, so use them with care, especially large multidimensional arrays.
Lastly, for multidimensional arrays it should be noted that only the last dimension can be resized. That means that given our example above, once we created the array with two CD racks, we would not be able to add more racks, we would only be able to change the number of CDs each rack held.
