Creating
Windows Services in .NET
While Windows service applications (previously called NT Services) have been
around for a long time, Peter Aitken says they were "a real bear" to
program. VB.NET (or any full .NET language) can now create Windows services
easily. Learn how to create Windows services and simplify developing
applications that run for extended periods and don't require user interaction.
Getting
Started with Remoting in .NET
Remoting lets isolated processes communicate with each other and can improve
security and stability at the same time. While the idea of getting two processes
to communicate is a simple one, the process is much more involved. Nonetheless,
the .NET framework simplifies remoting enormously. In this article, Peter Aitken
gives you the sample code and information you need to get started.
Upgrade
Your INI Files to XML with .NET
If you're migrating applications to .NET, you should also consider migrating
those old INI files. Russell Jones shows how you can easily translate them to
XML, use them from .NET without making Windows API calls, and simultaneously get
rid of the limitations imposed by the obsolete INI file format.
Another Chapter from Bellinaso's
ASP.NET Website Programming
"ASP.NET Website Programming - Problem Design Solution" by Kevin
Hoffman and VB2TheMax member Marco Bellinaso shows you how to build an
interactive website from design to deployment. Packed with solutions to website
programming problems, this book will have you building well-engineered,
extendable ASP.NET websites quickly and easily. With "ASP.NET Website
Programming" you will learn to Establish a solid, scalable website
foundation; Provide flexible user accounts integrating with ASP.NET's built-in
security; Create message forums that enable formatted messages but defend
against cross-site scripting; Generate revenue from advertising; Build a web
interface for uploading, downloading, editing, and managing the files on your
site; Add opinion polls, email newsletters, and news management; Deploy the
finished site on a live server; Build websites using good n-tier coding
techniques. The site we build is modular. You can slot the modules into your own
website, modify them, or use them as examples of particular ASP.NET techniques.
A few weeks ago we uploaded Chapter 4 "Maintaining
the Site"
This week we've added Chapter 11 "Deploying
the Site"

Tip
of the Week: Release COM Objects Immediately
When you use a COM or COM+ from a .NET application and then you set the object
reference to Nothing (or let it go out of scope), the object isn't released
immediately. The reason: your program communicates with the COM object through a
Runtime Callable Wrapper (RCW) object, which is responsible for the real
object's lifetime, thus the object will be actually released only when the RCW
is garbage collection, which might happen several minutes later or even only
when the entire application is shut down.
In most cases this behavior is acceptable, but at times it may be essential that
the COM object be explicitly released when the .NET application doesn't need it
any longer. You can do this by calling the ReleaseComObject static method of the
Marshal class (in the System.Runtime.InteropServices namespace):
' Create the object
Dim obj As New MyComObject()
' Use it
' ....
' Explicitly release it
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
obj = Nothing
Microsoft named its rich-UI framework Windows
Forms, but you can take it beyond forms to develop any type of rich-UI
application you're familiar with, from dialog-based to MDI apps. Here's how to

MICROSOFT: COVERING THEIR BETS WITH .NET | Analysis
Nothing polarizes an Internet technology discussion than the mention
of Microsoft. In one corner you have Microsoft and its supporters,
steadfastly sticking to the belief that Microsoft is a powerful, but
fundamentally honest competitor who continually drives innovation to
meet customer needs. In the other corner are the Microsoft-haters,
who clamor about how Microsoft is an evil monopoly hell-bent on
taking over the Internet, and eventually the world. Microsoft's
development of its new .Net Web Services platform has only added fuel
to the fire. Customer-focused innovation? Or arrogant, irrational
hubris?
