This article is the last part of the three part series on SynchronizationContext. SynchronizationContext is a class introduced by .NET 2.0 with little documentation or explanation of how to use it. I have tried to explain in part one how to use this class, and in part two, how to create your own SynchronizationContext. In part two, I showed how to build a SynchronizationContext that will marshal code from any .NET thread into a STA thread. I have done this so I can execute COM code that needs to...

Multithreaded programming can be quite difficult, and there’s a tremendous body of concepts and tools to learn when one embarks on this task. To help out, the Microsoft .NET Framework provides the SynchronizationContext class. Unfortunately, many developers aren’t even aware of this useful tool....

How to Resolve synchronization errors after migrating MS-Exchange mailbox  Version: 0.00     Price: $0.00

Migration of Exchange mailbox can be done with the ExProfre.exe tool. But at times, when the ExProfre.exe tool migrates the Exchange Server user profile, it results in numerous synchronization problems. Synchronization error messages appear in the event log. In such pathetic situations, you face problems while converting OST file into PST file. To overcome these situations a third-party OST to PST converter is needed. With the help of a converter, you are able to convert OST to PST with much eas...

Use Data Caching Techniques to Boost Performance and Ensure Synchronization  Version: 0.00     Price: $0.00

Performance is an important concern for any application, but becomes critical when the app is a Web Service accessed by thousands of clients simultaneously. One hardware approach to distributing Web Services requests evenly is a Web farm consisting of multiple servers. Once on a Web farm, Web Service performance can be improved by using ADO.NET DataSet objects to cache frequently accessed data, reducing round-trips to the database. Here the author describes data caching in a Web farm environment...

This short article is about the three less well understood methods of the Monitor class: Wait, Pulse, and PulseAll. The MSDN documentation for these methods explains what they do, but not why or how to use them. I will try to fill this gap and demystify them....

By far, the most common use of thread synchronization is to ensure mutually exclusive access to a shared resource by multiple threads. In the Win32® API, the CRITICAL_SECTION structure and associated functions offers the fastest and most efficient way to synchronize threads for mutually exclusive access when the threads are all running in a single process. The Microsoft® .NET Framework doesn't expose a CRITICAL_SECTION structure, but it does offer a similar mechanism allowing mutually exclusive ...

The article introduces a method of synchronizing two PostgreSQL databases. Although, this seems to be an easy task, no product (slony, londiste, ...) really satisfied the needs within the maps.bremen.de project. Either they have special prerequsits that didn't apply for our problem or they didn't support synchronizing of large objects....

I don't know why, but there is really not much information about this new class within the .NET framework. The MSDN documentation contains very little information on how to use SyncrhronizationContext. Initially, I must say that I had a hard time understanding the reason for this new class and how to use it. After reading a lot on the subject, I finally understood the purpose of this class and how it should be used. I decided to write this article to help other developers understand how to use t...

In part one, I explained the role of SynchronizationContext within the .NET framework 2.0. It is mostly used to allow threads to communicate with the UI thread. We have learned in part one that the SynchronizationContext by itself does nothing to marshal code between threads; in fact, this class should be an abstract class. The .NET framework provided us a version of this class to marshal code into the UI thread, but what about coding your own version of SynchronizationContext to do something el...

While developing a multithreaded application it is very important to maintain synchronization between multiple calls to the same method. Consider for example that you have a function that writes to a file. If at the same time multiple threads call this function it is bound to throw an exception as previous method call is yet to finish with the file. To avoid such situations you can use Monitor class....

Microsoft Sync Framework is a comprehensive platform for synchronizing offline and online data, and facilitates collaboration and offline access for applications, services and devices alike. It is protocol- and database-independent and includes technologies and tools that enable device roaming, sharing and the ability to take networked data offline before synchronizing it back at a later point in time....

In my last column, I showed the various thread synchronization mechanisms employed by the Microsoft® .NET Framework (see Concurrent Affairs: Performance-Conscious Thread Synchronization). I then examined the performance characteristics of all these mechanisms and determined that the Interlocked methods performed the best because the calling thread never has to transition to kernel mode. I then looked at how to build some simple locks using the Interlocked methods....

Welcome to part 7 of the Debug Tutorial series. In this section, we will learn about locks and synchronization objects in Windows.

This way, we get the best of both worlds....

Creating multilingual applications while being easy and improving greatly with each version of the .NET Framework, making the translations or replicating your fallback resource file across languages is a daunting task.

What happens is during the development of your application, you create key/value pairs in your .resx files, one at a time. This is not difficult, and VS.NET has a pretty good editor for resx files right there in VS.NET design environment itself. So far, so good....
