Handling Events in VB.NET
Visual Basic .NET event handlers have a common architecture that always uses the arguments sender and e to provide the ability to write code that does whatever is needed. But using these arguments isn't always the same. This article explores the techniques that you can use to handle events in Visual Basic .NET.

Display a PDF With VB.NET
PDF is an Adobe format for presenting documents. But since Adobe is a competitor to Microsoft, there's uneven support for the format in Microsoft products. You can save Office files as PDF files, but Microsoft doesn't provide any software tools for integrating the format into systems created with VB.NET. But you can do it anyway. This Quick Tip shows you how.

ImageList in VB.NET
The ImageList control has been a feature of Visual Basic since VB6 days. But most people don't use it, probably because it's just not clear to many programmers what the ImageList will do. This article explains it.

Disposing Objects in VB.NET
Disposing an object is something that you won't have to worry about in VB.NET very often. .NET includes a technology called Garbage Collection that usually takes care of everything silently and efficiently. But occasionally, usually when using file streams, sql objects or graphics (GDI+) objects, you may need to take control of disposing objects in your own code. Or, you might write your own class that implements the IDisposable interface. This article gives you some useful advice.

IEnumerable and IEnumerator
IEnumerable and IEnumerator are frequently tossed into technical articles these days. That's because this technique forms a core element of .NET technology. Unfortunately, the articles don't say a thing about what they do. This article, written in the 'from the ground up' style, fills in that missing explanation.

The basics that you need to code in Visual Basic .NET are explained in this segment of the About Visual Basic VB Express tutorial. This doesn't cover all of the language in detail because you can get that at Microsoft's site and in the Help for VB Express. What it does is show you where you can get information and briefly explain the basic structure of the VB.NET language.

Application Settings in VB.NET
VB.NET gives you a great new way to save application settings like connection strings or size and color by application or by user. The methods used in VB.NET are different than the ones in VB.NET 1.1 and other .NET languages such as C#. But technical articles I have read and even on Microsoft's own pages make mistakes. The goal of this article is to clear up as much confusion as possible, but some remaining problems are documented in it as well.

VB.NET Region Directive
In the very first edition of VB.NET, compiler generated code was kept in a hidden Region section to protect it from being accidentally changed. When Framework 2.0 was released, Microsoft started using partial classes to do the same thing. But the Region directive is still available to programmers to use to make their own code better organized and easier to read. This Quick Tip shows you how to use it, and why.

Chart Control in VB ASP.NET
ASP.NET 4.0 has added the Chart control as a standard feature. It was available in ASP.NET 3.5 as a download. Writing the code for the charts themselves is reasonably complex, mainly because charts are reasonably complex. But the question that pops up most often isn't about the coding the charts. It's about how to make the Chart control work in the first place. That's what this article is about.

TableLayout FlowLayout VB.NET
The ability to design your application interface was given a huge boost when Microsoft intoduced the two new controls TableLayoutPanel and FlowLayoutPanel in Framework 2.0. Using these controls, you can create forms where the other controls, like Textbox and Listbox, stay right where you want them to be. And you can even get autosizing effects that were previously only available with third party purchased controls. This article shows you how to get the most from these controls.

A structure and a multidimensional array have a lot in common in Visual Basic .NET programming. Often, you can use either one and your program will work just as well either way. But there are some clear differences. This Quick Tip helps you understand both of them so you can manage information inside a program better.

Class Declaring Reference Type
A reference type in VB.NET is an object stored in a type of memory called the Heap. Program code doesn't use the memory directly; it uses pointers to the memory instead. If you create a class in your code and then instantiate the class as an object, it's a reference type. But there are several ways in VB.NET that you can declare one. This article explains these different methods.

In VB 6, it was common to be required to use Windows API calls to get things done. In VB.NET, it doesn't happen very often, and, quite frankly, it's a lot harder to do. Before .NET 2.0, using SetEnvironmentVariable was one one of the times when a Win API call was necessary. This article shows you how to call this API in Windows.

Casting in VB.NET - Part One
Casting is the process of converting one data type to another, for example, from an Integer type to a String type. Some operations in VB.NET require specific data types to work. Casting creates the type you need. Part One of this two part series introduces casting. This article comparies the performance of DirectCast, CType and TryCast.

Using Namespaces in VB.NET
Namespaces keep Visual Basic .NET organized. .NET by itself is huge and the names of individual software objects frequently overlap. Add in the code that all of the .NET programmers write and you have a giant pot of names that would be chaos if there wasn't a way to organize it and keep one software object from interfering with another. The way it's done is namespaces. This article explains what they are and how to use them.

Simple Databases in VB.NET
A lot of programmers still use a sequential file when they need to save and retrieve data in a Visual Basic program. There are a lot of better alternatives, however. Free programming tools from Microsoft make it easy to use a database rather than a sequential file. And the new SQL Server Compact 3.5 database files make it even easier. This article shows you how it's done.

Part 10 of an Intro to VB.NET
Part 10 of the Visual Basic .NET 2010 Express tutorial is all about the vastly expanded ways that different kinds of collections can be programmed. In addition to a very flexible Array, VB.NET also provides Collections, Stacks, and Queues and lots of methods and properties for all of them. The Signature Block program is upgraded to allow multiple blocks in this segment as well.

Extension Methods
A normal class has to be instantiated as an object before the methods in it can be used. But if a method is shared, then the class it's in doesn't have to be instantiated and the method can be used directly. What if you need both? Then you need a feature introduced in VB.NET 2008 called extension methods. This article tells you how that works.
