Silverlight, HttpWebRequest, HTTP Stacks and the UI Thread

This one comes from a customer who thought that they were seeing an issue in using the browser HTTP stack in Silverlight to make lots of HTTP requests. The issue seemed to be that the stack was blocking the UI thread and causing the UI to stutter. The suspicion was that the blocking was occurring while data was being read from the stream that is handed back to you when you’re reading an HTTP

MVVM Light - what's the Messenger?

MVVM Light offers a class specific to every ViewModel instance that is used in the context of an application - Messenger. One might ask - what exactly is it and why it is needed?

Android HTTP Camera Live Preview Tutorial

The Android SDK includes a Camera class that is used to set image capture settings, start/stop preview, snap pictures, and retrieve frames for encoding for video. It is a handy abstraction of the real hardware device. However, the SDK doesn't provide any camera emulation, something that makes testing camera enabled applications quite difficult. In this tutorial, I am going to show you how to use

How I store Enumerations in the Database

One of the things I come across in databases now and then is a collection of single tables with a name like "MessageType". You have a look in them and it turns out to have 6 or so rows with no foreign key relationships.

Thread safe observable collection

If you ever wrote something more, then standard UI input-output, you sure got into wide range of exceptions like “The calling thread cannot access this object because a different thread owns it” or “This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher thread”. What the problem? The problem is old like condom in my wallet

Why should I use ObjectDataProvider?

There are many ways to instantiate an object that will be used as the data source for bindings. I have seen many people create the object in code and set the DataContext of the Window to that instance, which is a good way to do this. You may have noticed that I have been adding the source object to the Window’s Resource Dictionary in most of my previous posts, which works well too. We have an

Protocol Buffers and WCF

WCF performance has many aspects. In the previous series I explored how using GZip/Deflate compression can increase performance in areas with low network latency. However, the penalty is that the CPU utilization is much higher. Therefore, it does not apply to many people's situations. Instead of compressing messages after they are built, it would be better if we could build smaller messages.

Corning is not only imagining those scenarios – the company is engaged in research that could bring them alive in the not-too-distant future. You can get a

Why is there the message '!Do not use this registry key' in the registry?

Under Software\Microsoft\Windows\Current­Version\Explorer\Shell Folders, there is a message to registry snoopers: The first value is called "!Do not use this registry key" and the associated data is the message "Use the SH­Get­Folder­Path or SH­Get­Known­Folder­Path function instead." I added that message.The long and sad story of the Shell Folders key explains that the registry key exists only

A simple way to run C# code from bat file

I read an interested article demonstrated how to run a bat file with embedded C# code. I repost this example here, because the original post is written in Russian. Despite the fact that there are other more powerful solutions and frameworks to achieve the same goal (e.g. Powershell) – I think the way presented by the author, is very useful for different scenarios. /*@echo off && clsset WinDirNet=

IIS7 Native API (C++) Starter Kit

OverviewTo extend the server, IIS7 provides a new (C++) native core server API, which replaces the ISAPI filter and extension API from previous IIS releases.

NOTE: The IIS7 native (C++) server API is

"Cool" button creation in Expression Blend Tutorial

In this article we will look at some of the ways to create “cool” or gel buttons in Expression Blend. If you look at the default look and feel of a WPF button in Expression Blend or Visual Studio, you will notice that it doesn’t look “cool”. It’s still that dinosaur chrome looking button control, whereas Expression Blend and Windows Presentation Foundation (WPF) are not just about functionality

Named Pipes in WCF are named but not by you (and how to find the actual windows object name)

If Windows Communication Foundation (WCF) implementation has its own idiosyncrasies, named pipes provider is the champion. First, let’s start with the name of the provider. Named Pipes in Windows can be used to communicate between process on the same machine or between different machines across a network. WCF only implements the on-machine part of it. Named Pipes name has the format \\ServeName\

Loading Assemblies off Network Drives

.NET 4.0 introduces some nice changes that makes it easier to run .NET EXE type applications directly off network drives. Specifically the default behavior – that has caused immense amount of pain – in previous versions that refused to load assemblies from remote network shares unless CAS policy was adjusted, has been dropped and .NET EXE’s now behave more like standard Win32 applications that

Debugging WPF and Silverlight Binding Errors In Visual Studio

Recently I was working with a Microsoft Silverlight project, debugging a XAML binding error. After a few hours of searching, I found a blog describing how to alter the WPF Trace Settings to enable a more verbose output while debugging. After changing the trace level, you will see a more detailed output in the Debugger Output Window. Below is is a screenshot of the how to enable the proper

Detecting Certificate Authority compromises and web browser collusion

The Tor Project has long understood that the certification authority (CA) model of trust on the internet is susceptible to various methods of compromise. Without strong anonymity, the ability to perform targeted attacks with the blessing of a CA key is serious. In the past, I’ve worked on attacks relating to SSL/TLS trust models and for quite some time, I’ve hunted for evidence of non-academic CA

Revocation doesn't work (18 Mar 2011)

When an HTTPS certificate is issued, it's typically valid for a year or two. But what if something bad happens? What if the site loses control of its key? In that case you would really need a way to invalidate a certificate before it expires and that's what revocation does. Certificates contain instructions for how to find out whether they are revoked and clients should check this before

Hacker Spies Hit Security Firm RSA

Top security firm RSA Security revealed on Thursday that it’s been the victim of an “extremely sophisticated” hack. The company said in a note posted on its website that the intruders succeeded in stealing information related to the company’s SecurID two-factor authentication products. SecurID adds an extra layer of protection to a login process by requiring users to enter a secret code number

It offers an intuitive API and a modular architecture to easily add support for new codecs, container formats and transmission

Synchronization Contexts in WCF

One of the more useful features of the Windows® Communication Foundation (WCF) is its reliance on the Microsoft® .NET Framework synchronization context to marshal calls to the service instance (or to a callback object). This mechanism provides for both productivity-oriented development and for powerful extensibility. In this column, I describe briefly what synchronization contexts are and how WCF

WCF Service InstanceContextMode and ConcurrencyMode combinations

What does the InstanceContextMode and ConcurrencyMode attributes in a wcf service do?A short MSDN description of this describes it as follows: “A session is a correlation of all messages sent between two endpoints. Instancing refers to controlling the lifetime of user-defined service objects and their related InstanceContext objects. Concurrency is the term given to the control of the number of

IKVM.Reflection Update

Missing MembersTo support mcs I previously added some limited support for missing members. This has now been extended substantially to allow full fidelity reading/writing of assemblies. Normally IKVM.Reflection behaves like System.Reflection in how it tries to resolve member and assembly references, but now it is possible to customize this to enable reading a module without resolving any

Stored Procedure Definitions and Permissions

I wrote a post a while back that showed how you can grant execute permission ‘carte blanche’ for a database role in SQL Server. You can read that post here. This post is going to build on that concept of using database roles for groups of users and allocation permissions to the role. I recently had a situation where a tester wanted permission, for themselves and the rest of the testing team, to

A Silverlight Resizable TextBlock (and other resizable things)

In this blog post I present a simple attached behaviour that uses a Thumb control within a Popup to adorn any UI element so that the user can re-size it. A simple feature that has become quite popular on the web is to attache a small handle to text areas so that the user can resize them, this is useful if a user wants to add a large piece of text to a small comment form for example.

Using Query Classes With NHibernate

Even when using an ORM, such as NHibernate, the developer still has to decide how to perform queries. The simplest strategy is to get access to an ISession and directly perform a query whenever you need data. The problem is that doing so spreads query logic throughout the entire application – a clear violation of the Single Responsibility Principle. A more advanced strategy is to use Eric Evan’s

Wrapping a not thread safe object

Introduction    A colleague came to me with a question the answer for seemed very straight forward, yet an implementation took us more than a few minutes. The question was: I have a legacy object which is not thread safe, and all its methods, by its nature, synchronous. It was originally written to run on GUI thread in client application. Later on, this object had to be moved to server where it

Handling WP7 orientation changes via Visual States

It is pretty well known that an app can be notified of the phone’s orientation changes via the PhoneApplicationFrame.OrientationChanged event. However, if you are as serious about sharing the work between the designer and the developer as I am, you will not be happy with this – the changing of the layout should be the responsibility of the designer, not the developer. Of course, the best way to

Compressing messages in WCF part two - Expanding the GZipMessageEncoder and fixing another bug

The GZipMessageEncoder is a great sample for learning about MessageEncoders in general. In this post, I will expand the GZipMessageEncoder to do both GZip and Deflate compression. This will accomplish two things: (1) explain various pieces of a MessageEncoder and (2) set a groundwork for future posts. Since the MessageEncoder will now support both GZip and Deflate, it would be a good idea to

Figuring out why my SVCHOST.EXE is at 100% CPU without complicated tools in Windows 7

The SvcHost.exe process hosts services that run in the background on Windows. It's literally "Service Host." You may have a dozen services or more running inside that process. More complex is that you'll sometimes see multiple SvcHost.exe's in your TaskManager.  Let me tell you now, Task Manager will not save you. You can see the PIDs for a running Service for the Services tab, but when a service

Delay Binding Updates within a certain Context

This came up on Twitter today and since I have a solution that's been working well for me I opted to share. When making a series of data changes that will update Bindings, How can you keep a WPF/Silverlight UI from reflecting any of these changes until you're all done?  In other words, we need the ability to treat a series of Property changes as a single unit of work. While this works better with

How does the C runtime know whether to use the static-linking or dynamic-linking version of the header file?

In response to a description of what happens when you get dll­import wrong, nksingh asks, "This seems like a problem for the CRT. As far as I know, VC gives you the option of statically or dynamically linking the CRT. But it seems like the headers will have to make a choice to support one thing better than the other.

But not all have a blessed memory; moreover, there are better things to

Implement pagination with NHibernate ICriteria

I want to share my experience about implementing a pageable and sortable grids using NHibernate ICriteria. Many web applications use grids as a common representation of search results or list of data required by some business rules. We can extract data from database and paginate or order the records on the server side, but this creates a list of limitations in ordering the records and a big

Simple paging with ASP.NET MVC and NHibernate

This post demonstrates how you can do efficient paging using ASP.NET MVC and NHibernate.To make paging efficient we need to pass the start index and the number of records to return to the database. So that we can display page links we also need to pass some information to our view such as the number of pages available and the current page index. I found the cleanest way of doing this was to

Implementing the virtual method pattern in C#, Part One

I was asked recently how virtual methods work "behind the scenes": how does the CLR know at runtime which derived class method to call when a virtual method is invoked on a variable typed as the base class? Clearly it must have something upon which to make a decision, but how does it do so efficiently? I thought I might explore that question by considering how you might implement the "virtual and

Code Contracts

Code contracts provide a way to specify preconditions, postconditions, and object invariants in your code. Preconditions are requirements that must be met when entering a method or property. Postconditions describe expectations at the time the method or property code exits. Object invariants describe the expected state for a class that is in a good state. Code contracts include classes for

Kaxaml is a hobby and was created to be shared, so it's free! Feel free to download and try it out. If you don't like it, it cleans up nicely. Kaxaml is designed to be "notepad for XAML." It's supposed

Exception handling in T-SQL/TRY…CATCH – Underappreciated features of Microsoft SQL Server

As we continue our journey through the “Underappreciated features of SQL Server”, this week are are looking at a few of the T-SQL enhancements that the community felt did not get the deserved attention. This was in response to Andy Warren’s editorial of the same name on SQLServerCentral.com. Today, we will look at exception handling in T-SQL using the TRY…CATCH statements introduced since SQL

WCF Extensibility – Behaviors

The first part of this series will focus on the behaviors. There are four kinds of behaviors, depending on the scope to which they apply: service, endpoint, contract and operation behaviors. The behavior interfaces are the main entry points for almost all the other extensibility points in WCF – it’s via the Apply[Client/Dispatch]Behavior method in the behavior interfaces where a user can get a

7 Ways to Protect your .NET Code from Reverse-Engineering

59 Open Source Tools That Can Replace Popular Security Software

It's been about a year since we last updated our list of open source tools that can replace popular security software. This year's list includes many old favorites, but we also found some that we had previously overlooked. In addition, we added a new category -- data loss prevention apps. With all the attention generated by the WikiLeaks scandal, more companies are investing in this type of

Debian GNU/Linux 6.0 (squeeze)

I have been a bit slack in not writing about the release of Debian GNU/Linux 6.0, which was made over a month ago now. A new Debian stable release is always a big deal, not least because it doesn't happen very often, and it doesn't happen on a predictable, regular schedule. It is also because Debian is the base used for a lot of other Linux distributions, including Ubuntu (and thus Linux Mint the

Application Recovery applies to

ASP.NET WF4 / WCF and Async Calls

How should you use WF4 and WCF with ASP.NET? For this post I’ve created a really simple workflow and WCF service that delay for a specific amount of time and then return a value.  Then I created an ASP.NET page that I can use to invoke the workflow and WCF service to test their behavior The Workflow DefinitionFirst off – let’s get one thing straight.  When you create a workflow, you are creating

Anatomy of a .NET Assembly - PE Headers

Today, I'll be starting a look at what exactly is inside a .NET assembly - how the metadata and IL is stored, how Windows knows how to load it, and what all those bytes are actually doing. First of all, we need to understand the PE file format. PE files.NET assemblies are built on top of the PE (Portable Executable) file format that is used for all Windows executables and dlls, which itself is

7000 Concurrent Connections With Asynchronous WCF

It’s rare that a web service has some intensive processor bound computation to execute. Far more common for business applications, is a web service that executes one or more IO intensive operations. Typically our web service would access a database over the network, read and write files, or maybe call another web service. If we execute these operations synchronously, the thread that processes the

Generating Open XML WordprocessingML Documents

This is a blog post series on parameterized Open XML WordprocessingML document generation.  While it is easy enough to write an purpose-built application that generates WordprocessingML documents, too often, developers find themselves building new applications for similar but somewhat different scenarios.  However, if we take the right approach, it is possible to build a simple document

Sainuu ... for people wondering what that is - its HI in Mongolian.. So here I am in Mongolia on my vacation and its going great... My blog will be neglected by me for the next couple of weeks..:) Ok now back to WPF.. One interesting problem that comes to mind is the Window occupying all screen space on Maximizing when the WindowStyle is set to None. So this means that even if we do have the

Understanding SynchronizationContext

SynchronizationContext - MSDN Lets You DownI 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 SynchronizationContext. 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

Amazon Accidentally Posts Android Apps, Reveals Pricing – Similar, But Sometimes Cheaper

According to Frank from the site, "This morning, just for funzies, I entered http://www.amazon.com/apps in the address bar and found

[WPF] Binding to an asynchronous collection

As you may have noticed, it is not possible to modify the contents of an ObservableCollection on a separate thread if a view is bound to this collection : the CollectionView raises a NotSupportedException : This type of CollectionView does not support changes to its SourceCollection from a thread different from the Dispatcher threadTo illustrate this, let’s take a simple example : a ListBox bound

How can I propagate changes across threads?

I hope you didn’t get your hopes up too much when you read the title for this post. This time, instead of showing off what we support in our platform, I will explain to you what we don’t. The scenario I have in mind is when you want to bind a control in the UI thread to a collection or property that is modified in a different worker thread.

SQL Server: How to Avoid Big Single Error Log File on Production Servers

One thing, strange I found on our production database servers was a BIG SINGLE Error log file. It was taking long time to open and exploring it for required information was even worse.

MonoDevelop often makes use of threads to run operations on the background. Although we make sure to invoke all GUI update methods through the main GUI thread, sometimes there is a bug and an update is done in the secondary thread, which causes all sort of random locks and crashes. To make it easier to track down those bugs, I created a simple profiler module for Mono which can detect invocations

Writing code in C# is really all about the programmatic manipulation of values. A value is either of a value type, like an integer or a decimal, or it's a reference to an instance of a reference type, like a string or an exception. Values you manipulate always have a storage location that stores the value; those storage locations are called "variables". Often in a C# program you manipulate the
