25.) Intercepting keys in custom UITypeEditor's - Introduction
by Palo Mraz on VB.NET Download Source Code Read Comments Rate this resource Viewed 10582 times Rating: 9 users 3.00 out of 5 Next > The article assumes that you're familiar with Visual Basic .NET and the Visual Studio .NET Windows Forms designer. When developing Windows Forms controls it is often useful to provide your own, drop-down type editors for some of the control's properties. Custom type editors provide for richer design-time experience and they might be the deciding factor...

26.) Writing Plugin-Based Applications - Introduction
by Tim Dawson on VB.NET Download Source Code Read Comments Rate this resource Viewed 20017 times Rating: 93 users 4.15 out of 5 Next > Doing this in .NET is actually slightly easier than in COM, in my opinion, and far more powerful. For instance, getting your COM plugins to show an interface within a dialog shown by the host application was a bit of a nightmare, and required calls to SetParent and inventive use of window styles to get working properly. This is trivial in .NET because of...

by Karl Moore on VB.NET Read Comments Rate this resource Viewed 7283 times Rating: 20 users 3.55 out of 5 Next > Checking whether an Internet connection is available isn5;t always as easy as it sounds. Admittedly, there is a Windows API call that can check whether a connection exists, but it5;s extremely fragile and returns incorrect results if the machine has never had Internet Explorer configured correctly. Oops. The best method is to actually make a Web request and see whether it...

29.) Implement Versioning in .NET
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...

30.) Call VB6 From .NET
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...
