Automatic Coding of multi-level classified archive ID numbers in the basic archive management module of ERP (V1.0)
This Stored Procedure implements the automatic encoding technology for multi-level classified file ID numbers. This version (V1.0) now only implements three-bit encoding at each level,
This version has the following features:Different codes can be generated based on different database ta
positioning (positioning) removes elements from the normal flow of documents and also overrides the box model-related styles, it is ranked first. The box model is ranked second because it determines the size and position of the component.Other properties only affect the interior of the component (inside) or do not affect the first two sets of properties, so it is followed.
Positioning
Box model
Typesetting
Borders and backgrounds

C # explain the basic content of operators and expressions frequently used in coding,[Preface]
As the saying goes, it's better to hit the iron, so let's sum up a little bit if you learn something about it.[Overview]
This summary mainly summarizes the operators, Operation expressions, and some additional content when talking about operators and operation expressions.[Operator]
The operators are similar to th

time you write, you can directly write non-repeated code, and the level will naturally improve.2. The code is easier to understand. First, the name should be standardized. Try to name it in a way that you can understand. Writing code again does not show how high your syntax is. Try to use easy-to-read statements, and it looks easy to find errors. In my course, I only use the simplest statement to write a program. I may not be able to take the test, but I still need to write a software. In our C

Forward prediction frame, the previous I or P frame was used to encode the prediction. Several B-frames can be inserted between I-frames and p-frames. B-frames are encoded from the nearest adjacent I-frames or p-frames for Bidirectional prediction. When a p-frame is formed, the reference frame storage only requires the storage of one frame of the image. When B frames are formed, the reference frame storage requires the storage of the first and second frames of the image. The image group GOP is

The most important habit, however, is to keep comments updated in a timely manner, because outdated comments are more misleading than those without comments.Additional reading

Think of annotations that give you a lot of hints about future readers of your code, and what the reader needs (not to read too much) is to understand your code only with comments and function attribute names. For example, when you have a five or six-line program that performs a specific task, if you provide a line of code for the purpose and why it is described here, the reader can skip the details directly. There is no hard-
