Windows Services. Generics in the .NET Compact Framework - Welcome to Live Mesh! Parametric polymorphism (aka Generics) is one of the most interesting new features added to .NET CLR and languages in version 2.0 (Whidbey).
There are many good articles describing the feature and its’ implementation for the full .NET CLR. For those who interested in the design fundamentals of generics I’d strongly recommend the article by Don Syme and from Microsoft Research, who originally designed and implemented .NET generics. Bulk Insert into SQL CE 3.5 in C# Adding much data to a SQL CE database can be very slow.
If you try to for example add 10000 single records in one table with normal SQL INSERT command’s it would take at least 50 sec. So this could really use a performance boost. After some research I found this site: This really put into perspective the different ways you could do a bulk import with SQL CE. And in my project I decided to test the 3rd option with the ResultSet. SQL Compact 3rd party tools. This is an attempt at a comprehensive list of SQL Server Compact Microsoft and 3rd party tools, both commercial and non-commercial.

There are some scenarios where need to check programmatically if the given file is a .NET assembly or not.
How do we do that? One way is to use reflection and try to load that file (assembly). If the assembly gets loaded, and doesn’t throw any exception, then yes, it’s a valid .NET assembly. If it’s not a valid file, then it’ll throw a “BadImageFormatException”. The idea of checking weather a file is assembly or not by loading it and checking if exception is thrown or not; doesn’t seem to be too clean way at least to me. .NET assemblies are regular Win32 PE files. Here is the code sample that does the same: The .NET File Format. Index Introduction The standards of the .NET format are public, you can find them on Microsoft and in your .NET SDK (look after "Partition II Metadata.doc"), but they are intended to be more like a reference, not really a guide.
So, the truth is that a description of the format can be useful. I mean, there's a huge difference between having the WinNT.h and having the full explanation of its structures and stuff. The documentation given by Microsoft has some explanations, but a lot of passages aren't very clear at all. Getting Started. Building a .NET Disassembler (Part 1) There was a time, long ago, when I was in college, and thought it would be awesome to crack code.
This largely means digging into the bytes of an application, and seeing how it works, and possibly modifying the application code to suit your needs. Back in the days where just about everything was C/C++ or at least native code, this meant using a disassembler (like win32dasm for example) and strong assembly language skills. Actually, before I go much farther with this:<legal_disclaimer> Disassembling or decompiling applications, reverse engineering, modifying code, etc all have possible legal ramifications.
Reading PE format using data marshaling in .NET - Sergey Akopov. I recently picked up a book on IL by Serge Lidin titled Expert .NET 2.0 IL Assembler.
It is by far the most interesting book that I’ve read on .NET internals, which is actually fairly easy to follow thanks to the friendly nature of the managed environment and the awesomeness of the author. If you want to satisfy your curiosity about disassembling and generating IL code, this is the best book on the market. Anyway, the first couple of chapters in the book go over the Portable Executable (PE) format which is really vital in understanding how your compiler pieces together assemblies and how the loader is able to resolve dependencies and get everything into memory to get things executing. While going through the explanation of the PE format in the book is enough to understand the bare minimum, i decided to go hands-on and write a little PE parser.
Before i throw down some code, I’d like to reference a few resources which will help in understanding the PE format better. So, where do we begin?

Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format. Long time ago, in a galaxy far away, I wrote one of my first articles for Microsoft Systems Journal (now MSDN® Magazine).
The article, "Peering Inside the PE: A Tour of the Win32 Portable Executable File Format," turned out to be more popular than I had expected. To this day, I still hear from people (even within Microsoft) who use that article, which is still available from the MSDN Library. Unfortunately, the problem with articles is that they're static. Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format, Part 2.
Ast month in Part 1 of this article, I began a comprehensive tour of Portable Executable (PE) files. I described the history of PE files and the data structures that make up the headers, including the section table. The PE headers and section table tell you what kind of code and data exists in the executable and where you should look to find it. Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format. Calculating Metrics and Searching with a CodeDOM (Part 8) Introduction This article is about basic analysis of code in a CodeDOM, such as calculating metrics on it and searching it. Sources are included. This is Part 8 of a series on CodeDOMs. In the previous parts, I’ve discussed CodeDOMs, provided a C# CodeDOM, a WPF UI and IDE, a C# parser, solution/project CodeDOM classes, covered loading type metadata, and handled resolving symbolic references in a CodeDOM.

Head First C# - Source Code. Why doesn’t MEF support open-generics for exports? Because MEF is not type based. Update: We’ve posted an extension for doing open generics in MEF contrib. Read about it here: I get this question all the time. Recently it popped it’s head on the forums in this thread (which I referred to in my last post) In that thread, Andrew was asking why the following does not work? Open-generic support in MEF Contrib. A while ago I said it couldn’t be done, at least without hacky string parsing. Folks weren’t happy and they let us know it including Oren. Our team know the power that open-generic support brings to systems, but at the time there was no clean way to implement it in MEF. Then a bunch of time passed, and we actually added some APIs to MEF which suddenly made achieving support a reality (thanks to Wes for pointing the path), and not in the hacky string-parsing way I had described.
It all came together a few weeks ago after I was pairing with my friend Karl Shifflett on the Cider team. Managed Extensibility Framework - Understanding ContractBasedImportDefinition & GetExports. May 3, 2011 at 9:35 AM Edited May 3, 2011 at 12:29 PM Hi, I'm not sure if this is a bug or my understanding of how this works is not clear: In the following code I would have expected exportedTypes to be an empty enumeration (i.e. no items) because of ExportedType class not inheriting from IExportedType (see commented out code on class definition) and the fact that the isPrerequisite parameter is set to true. Ideally I would only want exports that only match typeof(IExportedType) when the isPrerequisite parameter is set to true or have I misunderstood something? Математическая библиотека для .NET.

ЕСИА. Using the OPTION (RECOMPILE) option for a statement - Kimberly L. Tripp. I started this series with the post titled: Little Bobby Tables, SQL Injection and EXECUTE AS. I then moved to discussing some of the differences with the post titled: EXEC and sp_executesql – how are they different? Today, I want to address a few of the comments as well as continue with a few tips and tricks using these commands.
First off – could we have helped the performance of the sp_executesql statement? Yes… If we know that a statement returns a varying amount of data (based on the parameters supplied) then we can use the SQL Server 2005 feature WITH RECOMPILE to tell SQL Server that the statement being executed should have it's own plan created and that prior plans (if they exist) should not reuse the statement.

Demo Europe: VCs Get Their Pick Of Hungry Start-ups. It’s a great time to be a venture capitalist (VC) in Europe, according to Hendrik Brandis, co-founder and managing partner of German VC firm Earlybird – because everyone wants your money. Although the European scene is improving, the demand for funding still outstrips supply, Brandis told the first ever Demo Europe event, held at the Digital October conference centre in Moscow. This makes it ideal, evidently, for investors because the number of start-ups looking for funding means VCs are spoilt for choice. No IP, No VC. Матричные фильтры обработки изображений.
