Error Handling Visual Basic / Miscellaneous
When using your application, a user may encounter various types of problems, some of which could come from you by some negligence when you worked on the project. Some other problems could occur only at the time the application is being used. Some other problems could be caused by the computer on which the application is being used. While developing your application, you should anticipate as many problems as possible as take appropriate actions.
Inheritance Visual Basic / Miscellaneous
Inheritance is the process of creating a new class that is based on an existing class. When a class hold a foundation that another class can use, you can create the new class that is based on the old one: this is the foundation of class inheritance, or simply called inheritance.
How To Program A Barcode Maker Visual Basic / Miscellaneous
This tutorial will show you how to input data into a text box and get a barcode image from it. You will also learn how to work with clipboard and checksum controls.
How to Juggle 30 Balls Blindfolded Visual Basic / Miscellaneous
Visual Basic has become much more complex with each new version. Unless projects, particularly large enterprise ones are properly managed, embarrassing statistics such as those mentioned above will only worsen. This tutorial outlines some of the fundamental issues involved in developing large-scale distributed systems using Visual Basic 6.
Mixed Languages with Visual Studio Visual Basic / Miscellaneous
In this relatively short tutorial, we'll discuss the concept of mixed language programming (MLP). We'll go into some of the pros and cons and considerations of doing MLP with Visual Studio.
Minutiae Visual Basic / Miscellaneous
This tutorial is going to cover a rather broad range of information about Visual Basic. Think of this tutorial as a Visual Basic programmer's smorgasbord. You'll learn about such topics as the advantages and disadvantages of compiling to p-code and native code. You'll get some hints on how to optimize your applications beyond just writing excellent code.
DIB SECTION Visual Basic / Miscellaneous
DIB Section is a type of Bitmap which is organized on the same structures DIBs are managed on but with the facilities of DDBs.
Ways of doing Image Processing Visual Basic / Miscellaneous
The Windows GUI is standing upon two pillers. Vector Graphics and Bitmap Graphics. Being quite difficult to manage, Vector Graphics are always very painful to handle but the possiblities are nearly impossible to find a limit. Where as Bitmaps are concerned, they are heavy Windows objects ( though DIBs are not ). Since the arrival of electrifying GUIs in the Windows, the interest of programmers towards Image Processing has awfully increased. This article shall tell you how to do it and how to make it work faster.
Animations using DIB Section Visual Basic / Miscellaneous
Random animations are always nothing more than a good procedure which must be able to run for always and must be able to calculate certain random values. In our case the randomely calculated values are the points (X,Y,Z).
Polygons Visual Basic / Miscellaneous
This short tutorial teaches you how draw polygons using the windows API. The windows API are the functions that windows uses to run so you should be careful using them as they can crash windows.
Graphics Commands Visual Basic / Multimedia
In VB there are a limited number of graphics features, but mixed with the judicious use of the Windows API a programmer can create some pretty fair graphics applications. When VB falls short, there is also no shortage of third party OCXs which can step in and add to the capabilites of VB.
Command Descriptions Visual Basic / Getting Started
In the earlier lesson you were introduced to coding, and reviewed a chart which groups VB commands into useful categories. In this section of the tutorial, I take each one of the commands and provide the syntax and a brief description of what the command does. For details, you can turn to the VB HELP file. My intent is to allow you to skim quickly over the commands to determine which one can help out in your situation.
Printing Visual Basic / Miscellaneous
An important fact is that how well the data is presented to the user can make or break the success of the application. Learning to use the printing tools of VB is critical to your success as a programmer.
Saving Files Visual Basic / File Manipulation
Visual Basic has built in file handling functions. These are not the fastest functions but it is not noticeable unless you are handling very large files. There are two common ways which we will cover in this tutorial. I consider these two functions to be the simplest.
