1. MySQL has multiple rows that access tables. The most commonly used rows are sequential access and index access. Sequential access refers to browsing a table in one row, that is, full table scan. Disadvantage: It is very time-consuming and inefficient. Index access: Read Only the rows that show the required features, including at least one index, similar to the directory in the book.

CSS3 animation (1): 5 types of pre-loaded animation effects and 35 types of CSS
Animation effect:

By using the member function, you do not need to obtain the edit box.
To obtain part of the text in the editing box, you can send an em_setsel message, where wparam indicates the start position and lparam indicates the end position. However, if you want to obtain a part of the text, your focus must be on this text box:
SendDlgItemMessage(IDC_EDIT3,EM_SETSEL,1,2);m_edit3.SetFocus();
To sum up, seven Chinese methods are commonly used:

Given the string a and its length n and the specific position p, return the rotated result. 5 Test Examples:6 "Abcdefgh", 8,47 return: "FGHABCDE"8 */9 /*Ten eg:a = "Abcdefgh", n = 8, p = 4 One first, A is reversed, a = "
this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time.
