CLR Interop is simply a technique for making unmanaged and managed code callable to each other. This technology enables developers to reuse existing managed or unmanaged builds and, depending on their needs, weighs the simplicity of managed code and the flexibility of unmanaged code, choosing a programming language that is appropriate for its own reality, without having to think too much about the language in which the reusable component is developed. Interop Chinese means interoperability, sinc

I've noticed a trend in my own recent programming that leads to this month's column theme. Recently, I've done a lot of win32®interop in applications based on the Microsoft®.net Framework. I'm not saying that my application is full of custom interop code, but sometimes I run into the. Net Framework class library with some minor but complicated, inadequate content that can be quickly reduced by invoking the WINDOWS®API. So I think it's not surprising that there are any functionality limitations t

NET Framework-based applications.ProgramCompleted a lot of Win32 InterOP. I am not saying that my application is full of custom InterOP code, but sometimes I will. net Framework class library encountered some secondary but complex, inadequate content, by calling the Windows API, you can quickly reduce this trouble. Therefore, I think

The Invoke and BeginInvoke of Control are relative to the branch thread (because they are generally called in the branch thread to update the main thread ui). Invoke is immediately inserted into the main thread for execution, and BeginInvoke is executed only after the main thread ends. Recently, the Invoke and BeginInvoke involved a huge number of tasks, so I ch

Today I stumbled upon some information about invoke and BeginInvoke, and I was not quite sure of the difference between them. So it took a little time to study it. The biggest difference, according to MSDN, is that BeginInvoke is part of asynchronous execution. Control.Invoke Method (Delegate): Executes the specified delegate on the thread that owns the underlying window handle of this control.Control.BeginInvoke method (Delegate): Executes the spec

Recently, the invoke and begininvoke involved a huge number of tasks, so I checked some relevant information and sorted it out as follows.

I. Differences between dynamic proxy and static proxy. (1) The Proxy class code is fixed and won't be huge because of the increasing size of the business; (2) AOP programming can be implemented, which cannot be implemented by the static Proxy; (3) decoupling, for web services, you can separate the data layer from the business layer. (4) the advantage of dynamic proxy is non-intrusive code extension. The static proxy mode itself has a big problem. If the number of class methods is increasing, the

Because there is some configuration information that needs to be saved so that the next startup program finishes initializing, this is actually a kind of class persistence.

Some of the things that need to be programmed at the underlying layer of Wince recently are used in processes in PPC,. NET Compact framework does not support the process component. If you find these items online, you have never touched the underlying things before. I think it is better. Let's take a look at them! 1. With the support of. NET Compact framework, P/invoke can easily and efficiently develop applications suitable for mobile devices without

CURL (clients for URL) is a common command line tool used to transmit data based on URLs. It supports HTTP, HTTPS, FTP, and other protocols. In fact, on Windows, a similar command Invoke-WebRequest has been added since Powershell 3.0. The following Help information is displayed when you execute Get-Help Invoke-WebRequest. Take a look at the ALIASES section. The curl is in the column. That is to say, you can
