In essence, it accepts messages from producers, and delivers them to consumers. RabbitMQ, and messaging in general, uses some jargon. Note that the producer, consumer, and broker do not have to reside on the same machine; indeed in most applications they don't. "Hello World" (using the .NET/C# Client) In this part of the tutorial we'll write two programs in C#; a producer that sends a single message, and a consumer that receives messages and prints them out.
In the diagram below, "P" is our producer and "C" is our consumer. The .NET client libraryRabbitMQ speaks AMQP, which is an open, general-purpose protocol for messaging. Now we have the .NET client binary, we can write some code. Sending We'll call our message sender Send and our message receiver Receive.cs. In Send.cs, we need to use some namespaces: Set up the class:
Felice Pollano Blog - Multiple Charts with WPF Dynamic Data Display. I was looking for a good open source charting library and I noticed that is a little difficult to find something really useful and easy to use. I had a look at the WPF Toolkit charting library, a little old for sure, but look promising at a first glance. Unfortunately it is not so easy to use, not brilliant in term of speed and with some discutable behavior, as for example the absence of a way to remove the chart animation, or removing the fancy bullet in the line chart. By digging a little deeper I found the WPF Dynamic Data Display Even if it seems not recently updated in term of source code, it has a professional level functionality, easy to customize and use, and with some effort MVVM compatible. Make sure to download the unreleased latest source changeset because it is dramatically different from the released one.
Here below we show hoe to use this charting library for a very common task, creating multiple chart with the same X Axis. This is the only trick. Xaml Side: Microsoft Web API – the REST is done by WCF (Part 1) Postings published on this series so far: (c) geek&poke When speaking of SOA today, many developers still think about Web Services (which in case of .NET are ASP.NET Web Services or Windows Communication Foundation, briefly WCF) handling SOAP using XML and other standards to enable Remote Procedure Calls (read: calling functions on remote computers). As remote computers may be part of foreign domains or even available on the internet the need for authentication and authorization came up fast and has been satisfied by introducing the WS-Security extension to SOAP. Another need of course has been to have reliable messaging which lead to another extension called WS-Reliability.
In order to be able to describe schemas of SOAP messages WSDL had been introduced. As you can see, there is a great effort to exchange data between two endpoints on the network. And even worse: the list of extensions and format definitions is by far not complete, not to mention the problems arising in the wild. ASP.NET WebAPI Hosting Techniques. Download Sample Code Introduction In this article we shall see different methods of WebAPI hosting. We will be creating a class library for API Controller and reference the same in various hosting projects. If you started working with WebAPI , soon you will start copy pasting the WebAPI controllers and related things over and over in each projects say you have planned to host one in Console or wish to perform unit testing or host the same in IIS as Web Application. When you are hosting your WebAPI in IIS , all your API controllers gets compiled and will be available in the application domain so you can make a HTTP Web request to your API controller.
There is currently a bug associated with the WebAPI framework, When you are hosting your WebAPI in a console or windows service using HttpSelfHostServer , the HttpControllerDispatcher is unable to map the incoming URL request to the API controller if you are trying to reference the WebAPI as a class library. 1. 2. Background Using the code 1.
Your First Web API (C# HTTP is not just for serving up web pages. It is also a powerful platform for building APIs that expose services and data. HTTP is simple, flexible, and ubiquitous. Almost any platform that you can think of has an HTTP library, so HTTP services can reach a broad range of clients, including browsers, mobile devices, and traditional desktop applications. ASP.NET Web API is a framework for building web APIs on top of the .NET Framework. In this tutorial, you will use ASP.NET Web API to create a web API that returns a list of products. Software versions used in the tutorial Create a Web API Project In this tutorial, you will use ASP.NET Web API to create a web API that returns a list of products.
Start Visual Studio and select New Project from the Start page. In the Templates pane, select Installed Templates and expand the Visual C# node. In the New ASP.NET Project dialog, select the Empty template. You can also create a Web API project using the "Web API" template. Adding a Model That's it! WPF: TabControl Series - Part 1: Colors and Sizes. Introduction The out-of-the-box TabControl is pretty ugly (is that just my personal opinion?). Attempting to KISS, meaning i.e. simply changing the colors used for rendering the TabControl itself and/or the TabItems however will not give you all too much of a chance to "remedy" its appearance. Instead, you'll have to completely replace the control's Style (that is, its default template). I'll try to cover some aspects in the scope of this article. Overview This article is part of a multi-part series. Outcome: the result of what's covered in this article First, let's see what we'll be left with at the end of this article (in other words "lessening the ugly screenshot coming up next" Before we start, please note that I wrapped up everything provided in the scope of this article as a sample solution.
Also, you'll notice that, in the screenshots, the TabControl appears larger than it would be in a real-world application. Status quo: the default appearance Alright, let's get started. But wait!

C# 5.0/4.0 in a Nutshell - PredicateBuilder. Dynamically Composing Expression Predicates Suppose you want to write a LINQ to SQL or Entity Framework query that implements a keyword-style search. In other words, a query that returns rows whose description contains some or all of a given set of keywords. We can proceed as follows: IQueryable<Product> SearchProducts (params string[] keywords) { IQueryable<Product> query = dataContext.Products; foreach (string keyword in keywords) { string temp = keyword; query = query.Where (p => p.Description.Contains (temp)); } return query; } The temporary variable in the loop is required to avoid the outer variable trap, where the same variable is captured for each iteration of the foreach loop.
So far, so good. But this only handles the case where you want to match all of the specified keywords. Of all the things that will drive you to manually constructing expression trees, the need for dynamic predicates is the most common in a typical business application.

Using IFilter in C# Download source files and demo project - 33.7 Kb What's in a IFilter? The IFilter interface was designed by Microsoft for use in its Indexing Service. Its main purpose is to extract text from files so the Indexing Service can index them and later search them. Some versions of Windows comes with IFilter implementations for Office files, and there are free and commercial filters available for other file types (Adobe PDF filter is a popular one). So what else is new?
There are already quite a few articles and pieces of information on how to use the IFilter interface in .NET (see the Links section), so why write another article you ask? Issues with the current implementations These are the issues I and others have found with the current implementations, I'll discuss each in detail below: Extracting text from very large files. Extracting text from very large files public static string GetTextFromFile(string path) COM threading issues Adobe PDF filter crashing the application when it's closed.

Drag-and-Drop Attached File From Outlook (97 and above) to C# Window Form. Download source - 7.04 Kb Introduction Recently, I decided to write a quick program that would allow me to drag-and-drop an attached zip file from an e-mail message to a C# Windows Form program so that I could extract specific types of files to be printed. Little did I know that I would be stepping into a relatively unknown area of drag-and-drop technology, especially it appears as it relates to e-mail attachments. The purpose of this article is to provide a simple example of how to drag-and-drop e-mail attachments from Outlook to a C# Windows Form program.
This article will not teach the fundamentals of drag-and-drop. Background I teach computer programming (C++ mainly) at a local college. The issue became the amount of manual work required to extract the "solution" sets for potentially each homework problem, open a solution, print each of the source files, open the next solution, etc. Little did I realize that I was about to step into quicksand. And now we start the trip ..... Voila! Chat Application using Web services in C# Download EasyTalk.zip - 1.67 MB Introduction All of us are more or less using many of the chat applications available in the market everyday but still sometimes wonder of how it has been developed. This is a simple private chat application developed in DotNet using a web service. The application (EasyTalk, I named it) targets mainly the beginners who still sometimes fear of using the web service.
The audience will get a taste of how web servcie can be easily developed and can be used in a chatting application.

Download source - 27.18 KB Introduction The firm I work for sells a product that implements its own file server and runtime environment.
The code base is old and two years ago a project was initiated to create a new interface using C# and .NET 2.0. One of the features on the wish list was the ability to copy/cut/drag/drop files between the proprietary file server environment and Windows Explorer. Bringing files into the proprietary environment was easy through the use of the CF_HDROP format.
However, trying to extract files was proving to be a problem. Since the files do not exist in the Windows environment, the CF_HDROP format was not available. Using the Code This code implements a class called DataObjectEx that is derived from System.Windows.Forms.DataObject and System.Runtime.InteropServices.ComTypes.IDataObject. For this project, the following namespaces need to be referenced: The next method we need to implement is an override of GetData. Points of Interest History.
