GEF (Graphical Editor Framework) Eclipse project entry series (3) --- Draw2D demo, gef --- draw2d In the article "GEF (Graphical Editor Framework) Eclipse project getting started series (2) --- setting up the Draw2D development environment", I will introduce you to setting up the development environment of Draw2D. Next

In the "GEF (graphical Editor Framework) Eclipse Project Starter series (2)---draw2d development environment" article, I give you an introduction to the draw2d development environment of the building. Next, according to the software industry practice, need to show an example, so that everyone is more interested in learning and explore the technology. Well, nonsense, the author Jiehuaxianfo, using Dan Rubel,

After the binding is successful, the small circle is solid and saved again. Figure 3-3 bind a map control and code object Step 4: Save the project, Run "command + R", and debug "helloworld map ".

. NET Core series: 3. Use multiple projects. netcore Through the previous two articles, we have learned how to create a new project, how to generate and run our applications, and what the content in the project. json file (roughly) means. However, most projects usually require multiple projects or referenced class libraries. We want to create a class library project and an application project. How to refere

In the Mifare card, energy and data are transmitted through an antenna. The antenna in the card contains several turns of coils and is directly connected to the chip without additional components. The coil is embedded in plastic to form a passive non-contact card. The card reader sends a set of Fixed-frequency electromagnetic waves to the IC. The card contains an IC series resonance circuit, which is the same as the frequency of the reader. In this w

Excel Secondary Development Series Previously we talked about the Excel programming model and common Excel operations. In this section, I will explain how to create an Excel application-level secondary development program. Many useful materials can be found on Microsoft's basic website. Here we mainly talk about the secondary development of Office projects: http://msdn.microsoft.com/zh-cn/library/cc668205.aspx. 1. Create an Excel Project, for example:

There are rows of n squares, with red (red), powder (Pink), Green (green) Three colors each lattice, each color, requires that any adjacent squares can not be the same color, and the first and the first two squares also different colors. All the requirements of the coating method.Idea: Using recursive algorithms.A[1]=3,a[2]=6,a[3]=6There are two kinds of situatio

[Serialization] FPGA OpenGL series instances 3-8 Decoder Based on OpenGL I. Principle: Decoding is the inverse process of encoding. Its function is to identify binary codes with specific meanings and convert them into control signals. A logic circuit with decoding function becomes a decoder.The decoder can be divided into two types:CodeConvert to one of the valid signals. This decoder can be called a
