Physical intrusion, malicious it, and lack of good defense technologies make it difficult to effectively protect critical infrastructure networks. According to some security experts, helping water supply facilities, power plants and manufacturing operate and manage critical infrastructure networks is more vulnerable to a series of different threats than most information technology systems, it is difficult to defend against certain types of attacks. "For information security management personnel,

There are many rect records on the progress bar. Each rect shows an operation name. When the name is too long to display all records, you need to process the string. My method is to directly display the string in the middle of the rect when the length of the string is smaller than the width of the rect. When the value is greater than the rect width, the rect width must be used as the reference. Specific implementation of C ++CodeAs follows: csize size = dc. gettextextent (STR); If (size. C

Android GIS Development Series-Introductory season (5), in this article, we know how to find features. Now there is a need to find a point 5000 meters in the range of features, then how to do it? First we need to draw a circle with a radius of 5000 meters on the map and then query the relevant features based on the queryparameters. Specific as follows:One, draw a circle with a radius of 5000 meters1. Determine the center point: centerpoint2. Radius of 50003. Divide a circle into 120 points (whic

Common classes Crect: A class used to represent a rectangle. It has four member variables: Top left bottom right. The tables are the coordinates in the upper left corner and lower right corner. You can construct it using the following methods: Crect (int l, int T, int R, int B); Specify four coordinates Crect (const rect srcrect); constructed by rect Structure Crect (lpcrect lpsrcrect); constructed by rect Structure Crect (point, size); coordinate and Size Structure in the upper left corner Cr
