If WebBrowser1.Document. All (I). tagName = "HTML" Then
The Code 39 code rules are:1, each five line represents a character;2, The thick line is 1, the thin wire represents 0;3, the gap between lines of the width of the expression 1, a narrow representation of 0;4, five lines plus the four gap between them is nine-bit binary encoding, and this nine bit must have three bits is 1, so called 39 yards;5, the first and last of the bar
Java static code block, construction code block, and local code block
There are three types of code blocks to be learned, which have never been known before. Now we have sorted it out. As a note, I also hope to provide some help to the viewer.

Meaning: four-digit binary numbers are used to represent one digit in the value (0 ~ 9), BCD code for short, that is, BCD code.
It can also be understood that the decimal number is expanded into a binary number in the form of 8421 (14 is displayed as a binary number in the form of 8421, or 00010100 decimal number indicates 20)
The BCD code of 14 is 20.
The functi
Why?
The computer uses binary to represent a value. For example, decimal number 10 is expressed as 1010 in binary number. Set the computer to 8 characters, that is, 1 byte. The highest digit indicates the symbol. 0 is positive and 1 is negative.Let's take a look at the problems with the addition, subtraction, multiplication, division, and number represented by the original code:
Decimal: 1-1 = 1 + (-1) = 0
