ADO. NET is the core of. NET interoperability with the database, and the Ado.net entity database enhances the ability of the. NET application to interconnect with the database, and we can easily strongly type data interoperation with the underlying database through the Ado.net Entity Data model. Greatly facilitates the design personnel, thus also enhances the database operation security. A very special problem has recently been encountered when using the domain data service to siverlight [the results in the application are not the same as the results of the database], after repeated experiments, finally found ...

ASP.net 4.0 has been improved in many ways, and the ASP.net 4.0 white paper describes a number of ASP.net 4.0 mechanism changes and improvements. In my blog, there are also several articles about asp.net4.0 's feature modification. But as a whole new framework and runtime, there is certainly a lot of internal APIs and extension points that are not exposed as clearly. For example today from this article Three Hidden extensibility Gems in asp.net 4 introduction ...

First, Dotfuscator Professional version of the crack use Method 1 to copy the assembly files in the cracked patch to the vs2005 Dotfuscator Community version of the installation directory to overwrite the original file. The default installation path for the program is C:\Program Files\Microsoft Visual Studio 8\application\preemptive Solutions\dotfuscator Community Edition 2.

From the previous example, you can see that if you move your finger away from the screen while the picture is moving, the picture stops immediately, in which case WPF provides another inertia effect (inertia). 　　It allows the UI unit to move more physically, more realistically, and more smoothly. On the basis of the preceding code, additional manipulationinertiastarting events need to be added for <Canvas>. <canvas x:name= "Touchpad&q ...

On the Internet, there are many Silverlight projects released every day, some open source, some just for demonstration. In the early days of Silverlight learning, most of them need to imitate learning, so it is best to discover a Silverlight project that can view the source code. However, Silverlight Publishing is just publishing the resource bundle XAP, and all the resources are in this XAP file, how do you view the resources and code? Below I will demonstrate the method of Decompile, in the demo I will use Silverl ...

I believe most developers are more aware of caching, many developers use predefined or custom caching in software development, and get the expected performance boost from the application. This and subsequent articles will detail and discuss the mechanism of caching implementation under the. NET system, and discusses its advantages and disadvantages. . NET caching mechanism: using the actual value of the cache written in Kevinhoffman,lonnykruger's book: Developers often need to temporarily store data (temporary data) in a storage medium for quick access ....

On the last mention of the performance of memcached, indeed, the cache is not omnipotent, but there is no cache is absolutely not? It's true. PlentyOfFish is to do so, it is also the internet giants of the use of WISC (Windows + IIS + SQL Server + C #) architecture of the Web site, MS can not always take MySpace to say things, now of course will not let this opportunity to hype, But the irony is that people don't use server controls that look pretty.

by ASP.net MVC's built-in extensibility, developers can use third party libraries, such as jquery. 　　When using ASP.net webforms, it is more difficult to use jquery instead of asp.net AJAX. At the beginning of this article, the version of ASP.net mvc was preview 4, and some of the techniques used in preview 4 might not work in earlier versions. Preview 4 can be downloaded from the CodePlex. ...

1, why asp.net 2.0 data-bound controls do not need to write code to complete the update, delete, new and other data operations? ASP.net 1.x, a control such as the DataGrid uses an expression such as DataBinder.Eval (Container.DataItem, "ColumnName") to bind data from the data source to the control. However, it is not possible to automatically remove new values from the control while updating the data back to the database. So asp.net ...

Let me give you an example of three ways to generate a random number that is not duplicated by using 10 random numbers that generate 1-10:1. Using a while loop to generate random numbers through a while loop until a repeat is generated, this method is easier to think of, but inefficient, with the instance code as follows: static void Main (string] args) {int] result = new INT[10]; int tmp =-1; ...

In asp.net applications, the <%@%>, <%#%>, <%=%> that are commonly used on asp.net pages.       Use the <%$%> binding resource project in a globalized project to use <%:%> bind viewdata in asp.net mvc. &...

Dynamically add some additional responsibilities to an object. 　　In terms of extended functionality, the decorators pattern is more flexible than the way in which subclasses are generated.  Take the. NET Framework 2.0 System.IO class as an example. System.IO.Streampublic abstract class Stream:marshalbyrefobject, idisposable{public abstract int ...

At present, Wpf/silverlight technical data is very scarce in China, and only some basic tutorials. In order to more deeply analyze the technical connotation of wpf/silverlight, solve the difficult and incurable diseases in the development process, decompose the characteristic details of the practical application cases, the "Wpf/silverlight depth Solution" series is bred and born. The entire series of all articles are original, by my personal development experience combined with the relevant information compiled, the process will inevitably have mistakes or improper places also hope that readers friendly points out. ...

ASP.net MVC2 combines System.ComponentModel.DataAnnotations provides a very effective framework for entity validation. For the processing of error messages, it provides two choices by default: String constants are read from an assembly resource file But here we have our own resource file scenario, where we need to localize our control error messages. Because we can only supply constants in metadata, string manipulation is not possible. A more direct and troublesome way is to ...

Brahma is an open source library for parallel computing, written by C # and supported to run on a variety of processors. Currently, Brahma contains only one graphics processor (GPU) module, but its modular structure can support more kinds of processors. With Brahma, statements in the same C # method can run on both the CPU and the GPU without the need for additional code. Brahma performs parallel computations by converting LINQ statements into target processor code, and the generated code differs according to the target processor. For example, for dire ...

. NET always supports optional parameters, but the C # language does not support that optional parameters are usually prohibited except for invoking a COM library. Now, with the support of C # 4 for optional parameters, we can see that optional parameters are being used more and more, not just in legacy code. 　　These applications include interoperability with dynamic languages, read-only data types, and many places in asp.net mvc. Obviously, COM is still the main option for optional parameters. For example, when you use the Office library, a function may have more than 20 ...

Over the past 6 months, ASP. NET Development team has been publishing the preview version of ASP.net MVC 2, then the beta, and now the RC (the final version of the candidate version). Given that the final release is not too far off, I think it's time to start a new asp.net MVC 2 blog series with multiple sections designed to discuss new features and how to make the most of them. asp.net mvc 2 Last March, we released ASP.net MVC 1.0. Since then, almost a ...

Lucene.Net is an open source project for Full-text indexing that is currently widely used in. NET environments and is used for full-text indexing in project development. A few small problems in the development process are searching for multiple fields and multiple indexed directories. 1, a multiple-field search is to have more than one field of the content of the comparison search, similar concepts in SQL is select * from Table where a like '%query% ' or b '%query% '.
