that causes the problem is:for (thread_index = 0; Thread_index If the main thread is running fast enough (because the mainline threads is very fast for new threads after deleting sleep (1), it is possible to change the parameters of some threads (that is, Thread_index).at this point, passing the reference is not the appropriate choice, and the value is correctThis error behavior can occur when there is insufficient attention to shared variables and multiple execution paths. You need to be very

Design and Analysis of BASIC Program for arm9-based on S3C2440------- JustdoI have recently learned the design of the basic program of ARM9. I have recorded my experiences and hope to help beginners. To learn how to use the arm program, first go to the structure principle di

the exchange, so to the middle by, so fill: A + 1, N-2 There are many such problems, such as the split-half method and the root of the equation using the bipartite method. There are two things left behind: 1. A description of a small problem, that is, a recursive boundary. 2. A description of a big problem into a small problem.The small problem of finding out the split half method is: Low = high; the small problem of root of the binary method is FABS (x1-x2) PS: Let's try again. I didn't e

errors and events for communication controls are: Mscomm-er-break received 1 breaksignal MSCOMM-ER-CDTOCD Signal Timeout MSCOMM-EV-CDCD Signal Change 2, inquiry method. The program designer is responsible for reading the value of the commevent and handling any errors or events that occur. This approach is typically used for simple application design. 1.2 Properties of communication controls The key o

From: http://www.cnblogs.com/wangkewei/archive/2009/03/08/1406354.htmlI have read a lot of articles about user interface design recently and summarized them as follows:1. Two typographical messages: wm_size and wm_settingchange. We need to process typographical operations in these two messages.(1) If the window size changes, the window will receive the wm_size notification. The low text of the lparam parameter of the wm_size message specifies the new

A recently developed program requires a high speed of code. At the same time, because the implemented code speed cannot meet the requirements, it searches. Add this article to favorites. Source: http://www.kuqin.com/language/20090314/39898.html SummaryWhether you are willing to admit it or not, everyone wants the program to run faster and better. Every day, people catch up with me, as if tomorrow is the las

queries for each customer. In some cases, you may want to open an invoice, write the customer information you need to contact in the invoice header, and then list each item in order. Mysql is not suitable for these types of tasks, because it may depend on several queries of the first few query results, and these tasks are beyond the mysql layout design capability. In general, in addition to mysql, tools are also required to execute tasks that include

problems, they can also help users better use the system. In fact, all the programs have some of the same requirements for testability, so we can extract these requirements to abstract into a separate system (class), so that all programs can provide a unified testing interface.2. Some key points of design log class1) can be saved into a separate file, as the above analysis, some programs to perform a long time, must be the

Use the if statement to design the selection program. if statements are generally divided into two methods: Single-condition single-branch and single-condition dual-branch if statements. 1.1 General syntax for if statements with one condition and one branch: If (expression ){ Statement B; } Statement execution process: first, execute expression A. If expression A is not 0, execute statement sequence

I have been very excited since I received this classic masterpiece "window Program Design" at on May 23, March 2. This book gives me the feeling that I want to "C ++ primer plus", or better, both of them share a common feature that allows you to eliminate basic blind spots and lift your doubts from the past. Everything starts and ends. After 10 days, I only saw Chapter 10. Ah, it was a little slow, but bec
