Interface development requires a certain amount of time for both Web development and Winform development, especially for interfaces with a large number of database fields, generally, more controls need to be placed on the editing interface for data display. Every time this happens, it is a headache. Repeated mechanical operations make people very tired and annoying, however, this is required. Because database fields are related to the page layout, you can use the database metadata of the Code

CSharp database code generation tool and csharp Generation Tool There are many projects with many database table fields in the project, and I don't know when to press it one by one. I think it's a sudden whim to make a tool for all and for all. It took me one night to write this thing, and the code was messy. It took a lot of time to use this tool.

QR code generation and scanning, QR code generation and ScanningQR code generation and scanning collect the generation and scanning function code of QR codes. The scanning function includes scanning of QR codes and bar codes, which has a 360 scan UI effect and serves as a tool for QR codes. :Http://www.dwz.cn/z9GIySour

There are a number of strategies for garbage collection in Java, at present, the garbage collection of commercial virtual machines adopts "generational collection", which divides memory into several pieces according to the different survival cycle of the object, and generally divides the Java heap into Cenozoic and old years, and adopts a more suitable collection algorithm according to the characteristics of each age. The collection algorithm used in the Cenozoic: Replication algorithm. The idea

Abstract:Many companies often add their logo to the QR code for commercial purposes. However, if the logo block area is large enough, the QR code Becomes unrecognizable. Is there a way to "empty" the above area in advance (to specifically place the logo), while other areas are dedicated to placing the valid data of the QR code? -- This is the question to be discussed in this article. This article focuses on the advanced application and improvement of QR codes. The main idea isImprove the QR code

Use ILSpy to view the Session. SessionID generation algorithm and sessionid generation algorithm. 　　Reason In InProc mode, asp.net sessions are easy to lose and often need to be logged on again. distributed sharing is not supported. So when we are studying how to implement a native Session in Redis, we wanted to use GUID as the key to store the cookie, and we were wondering whether we could implement the sa

Generation Process of new part encoding and generation process of part Encoding1. Background 1.1 region-level code In the system, we divide the region-level codes into: district, street, community, and cell ). The numbers they correspond to are: Area: 2; Sub-District: 3; Community: 4; Unit grid: 51.2 tcregion table and vcregion table The tcregion table contains information about all regions.

than 100, so the corresponding questions are generated directly. The following class implements efficiency considerations in two scenarios. If traversal is fast, you can directly call AddTest to add one more time. If the query is fast, you can use KindOfTestNeed to extract the query conditions, the results generated by the current code are the same each time. If there is a real library, you can use the Randomization of the query results and the Randomization of the KindOfTestNeed condition to g
