File system object example
This tutorial will explain how to create a file system object in visual basic
File Handling
If you want to be an expert VB programmer then you'll need to know a lot about how VB handles files - what is possible and what is not, plus how to do something in the smallest code or in the least amount of time. To do this you need to understand the file handling features which VB offers.
Creating and sending HTML email in Visual Basic - Part 2
This tutorial briefly explains how to import HTML file into the message body and automatically attach pictures and other objects this HTML file depends on.
check whether a file exists

Internet Programming
In this tutorial I will cover how to perform file transfers between your PC and a web server.
Creating Multimedia Applications-Part II
Now, with some modifications, we will transform the CD player into an audio file player. This player will be created in such a way that it could search for wave and midi files in your drives and play them.
Projects
A typical VB application might consist of more than one forms, each of which may have multiple controls. In VB, the information about each form (it's own properties as well as those of the controls that are on the form) is saved into it's own file.
Command Descriptions
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.
Command Summary
Fact is, that few of the VB commands stand alone. More often than not, a command supports only one aspect of a topic. For example, the OPEN command opens a file so you can read it, whereas the LINE INPUT command reads one line of data at a time. And so it is in all of the areas of capability which VB supports. This page provides my own interpretation of VB command grouping.
Ping an ip address remotely
This VBScript provides the functionality for ping an ip address remotely by an IIS server. This file require IIS to access the ping.exe.
Playing WAV Sound Files in Visual Basic
Have you ever wanted to play a WAV file from your Visual Basic applicaiton? Here's the API call you need to use to play WAV files.
Learning the basics of programming
ACCESS provides two ways of interacting with the VBA language. The most useful of the two is saved modules that contain VBA procedures. Procedures are batches of programming commands that can be executed to do interesting things like process transactions against master tables, provide sophisticated error checking, and so on. The second way to interact with VBA is directly through the interpreter. When you type a
statement into the interpreter, it is executed immediately. Although there is little business use for this feature, it does making learning the language and testing new statements easier. (pdf file, install Acrobat Reader to read this tutorial)
How to Create and Call a Function in Visual Basic.NET
This tutorial will show how to create a function and how to call it. Using implementations of a button and label, a function is called and output to the user.
Built-In Procedures
If the .NET Framework doesn't have a function (or a class) you are looking for, you can create one and be able to use it over and over again in different programs. You can even create one or a series of commercial functions (or classes) and be able to distribute or sell it. To make this happen, you can "package" one or more procedures (or classes) in a library.
Creating VB Function For MS Excel
You can create your own functions to supplement the built-in functions in Microsoft Excel spreadsheet which are quite limited. These functions could be very useful and powerful if you know how to program them properly. One main reason we need to create user defined functions is to enable us to customize our spreadsheet environment for individual needs.
VB Overview
Visual Basic is a much-enhanced version of the BASIC programming language and the BASIC Integrated Development Environment (IDE). The bottom line of the enhancement is the VB can create Windows programs whereas BASIC could only create DOS programs. Ok, so the modifications are very major, but the idea holds true that Visual Basic is BASIC for Windows.
Creating Multimedia Applications-Part I
You can create various multimedia applications in VB that couold play audio CD, audiofiles, VCD , video files and etc.
To be able to play multimedia files or multimedia devices, you have to insert Microsoft Multimedia Control into your VB applications
that you are going to create.
How to create custom progress bar using Visual Basic
This tutorial will show you how to create custom progress bar using Visual Basic.
How to Create an Image Map in Visual Basic.NET
This tutorial will show how to create an image map with the help of ASP.NET’s ImageMap control. An ImageMap control displays an image on a page, and when a HotSpot region defined within the ImageMap control is clicked, the control either generates a postback to the server, or navigates to a specified URL. In this tutorial we will use a simple image of earth and display a message when the HotSpot region clicked.
Class Construction and Destruction
It should appear to us clearly by now that inheritance is useful by allowing us to use an object that was already created but "upgrade" it with new features that were not available when the original object was born. In most cases, when creating a class, you may not thing that other classes would be inherited from it. In fact, this will usually not be your concern: you simply create a class and use it as needed. In some other cases, rather as you build your experience with Visual Basic. You may create a class that, although useful at the time, you may already think of other classes that would be based on it. This means that, at the time you are creating such a class, you would already keep inheritance in mind. Visual Basic provides various features that can assist you with creating and implementing class with different goals in mind.

Creating database applications in VB-Part II
you have learned how to create a simple database application using data control. In this lesson, you will work on the same application but use some slightly more advance commands.
Graphics Commands
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.
Creating database applications in VB-Part I
Visual basic allows us to manage databases created with different database program such as MS Access, Dbase, Paradox and etc. In this lesson, we are not dealing with how to create database files but we will see how we can access database files in the VB environment.
How to Use a BulletedList Control
A bulleted list control adds a bulleted list to the web site. We are also able to choose what is put in the bulleted list. This item is best used when making headlines of steps, examples, etc. As you will see it is simple to create and use.
Introduction to Procedures
A procedure is a set-aside assignment the compiler must take care of to complement a program. A program developer writes the procedure and a user would only see the result. There are two categories of procedures you will use in your programs: those that have already been created thus made available to you, and those you will create yourself.In v basic, like most other languages, there are two types of procedures: functions and sub routines.
