I am a beginner. I wanted to share some experiences with other beginners. The first frustration we have is finding a book that teaches us what we want to learn. When looking at beginners books we all want to avoid the books that are too simple, but can\'t yet crack the secret code the upper level books. I think there is some secret language that developers talk in;...

Beginners and seasoned object-oriented programmers know that they create an instance of a class by invoking the class\' constructor preceded by the New keyword. For example, the following code constructs an instance of class MyClass by calling its no-argument constructor: New MyClass() You get one object each time a constructor is called. If you call a class\' constructor three times, you get three instances of the class. Also note that even if you don\'t write...

Technology Toolbox VB.NET, C# Other: .NET Framework Library E veryone wants reliable applications. The .NET Framework helps by minimizing conflicts between components with a new versioning strategy involving public and private components. And remember, .NET relies heavily on components. Private components reside in the same directory as the application using them. Applications don\'t consider component version when they\'re using private components; an app loads whatever physical file it...

Technology Toolbox VB.NET, VB6 W ithin the next few years, most shops will run a lot of VB6 code along with a growing amount of .NET code. You can make these two code bases interoperate as well as possible using the .NET runtime\'s interoperability services. These let you write Visual Basic .NET (VB.NET) applications that use existing VB6 ActiveX DLLs or other COM DLLs, and they let you write VB6 apps that use DLLs created with VB.NET. You can create .NET applications that leverage your...

Technology Toolbox VB.NET, SQL Server 2000, ASP.NET E ffective n-tier applications require consistent communication between the tiers. The .NET DataSet class helps this communication process by providing mechanisms for manipulating data in a single tier and transferring data between different tiers. In this column, I\'ll show you some of the ways the DataSet class can help you build a Web application that performs and scales better. First, a little background on Web application...

Technology Toolbox: VB.NET, C# V B6 lets you use the UserControl designer to create your own controls, but you must write a lot of delegation code to wrap up constituent controls\' properties and methods. .NET\'s object-oriented architecture lets you use inheritance to simplify the process of creating a control, allowing you to focus on the additional functionality you want to add instead of on delegation code. Take a look at this month\'s feature article, \" Subclass Controls in .NET ,\" to...

A DO.NET provides a unified programming model and a common set of classes for performing any sort of data access, regardless of the language you use to develop the code. Rebuilt from the ground up but aligned with ADO as much as is possible and sensible ADO.NET makes the transition from a client/server, connection-based model to a model that enables disconnected front ends to download records, work offline,...

Often we need to use TCP over IP sockets to do communications instead of the familiar HTTP protocol that web developers are used to. Prior to the arrival of the .NET platform, this usually involved a ton of Winsock code and C - style API declarations. I recently had to rewrite a TCP socket client class from VB 6.0 into .NET for communication to a mainframe system. I knew that if I ran the original VB 6.0 DLL project through the VB.NET...

Visual Basic .NET offers its users, among many other things, a fully object-oriented programming (OOP) experience. Some former VB6 developers have prepared themselves well to embrace this new version of the language. Others, however, need more time and guidance in taking on this new challenge and opportunity. In this VB.NET OOP series, Budi Kurniawan introduces many facets of object-oriented design and programming to VB programmers new to OOP. Discussions...

The dust has settled, and an uneasy peace lies across the land. Visual Basic .NET developers continue to struggle to remain loyal to VB. They know intellectually that VB is truly a first-class language in .NET but somehow they still don\'t quite believe it. Meanwhile, C++ developers have largely stayed aloof from the language wars, too busy trying to decode a multitude of language extensions such as: typedef __gc __managed __confused...
