EAN instance.The syntax format for Usebean is as follows:　　Where the id attribute is the instance name of JavaBean, the class property determines the implementation class of the JavaBean. The scope property is used to specify the scope of the JavaBean instance, which has the following 4 values:Page: The JavaBean instance is valid only on this page.Request: The JavaBean instance is valid for this time.Session: The JavaBean instance is valid within thi

Suppose that the contents of EAN are numbered from left to right: N13, N12, N11, N10, N9, N8, N7, N6, N5, N4, N3, N2, N1, where the N1 is the calibration bit to be requested: 1, c1= (n2+n4+n6+n8+n10+n12) *3; 2, C2=n3+n5+n7+n9+n11+n13; 3, add C1 and C2, take its single-digit number, set to C3; 4, check bit N1=10-C3 For example, here is an example of a EAN13 barcode: The top three 690 represent China, 690~694 on behalf of China, other maps can check

People with C + + development experience will find that we can use 0 as false, not 0 as true. A function is of type bool, but we can return the type of int and automatically convert 0 to False, not 0 to true. The code example is as follows: Copy Code code as follows: #include #include using namespace Std; the bool Fun ()//function return type is bool, but we can return the int type in the function. { return 1; } void Main () { int a=1; The IF (a)//a is of

In any other location, the hyphenation symbol identifies an ANSI character range.When a range of characters is specified, the characters must appear in ascending order (A-Z or 0-100). [A-z] is a valid pattern, [z-a] is an invalid mode.Ignore character order []; it is treated as a 0-length character ("").Reference address:http://office.microsoft.com/zh-cn/assistance/HP010322842052.aspx ////////////////////////////////////////////////////
