Create a Windows application and use multiple threads to scan a computer in a CIDR block. Obtain the DNS domain name based on the IP address of the computer. If the computer is not online, a prompt is returned. The initial interface is required.
After you enter the IP address range, click scan to automatically display the DNS information of each IP address in listboxstatus. The specific requirements are as follows:
(1) Verify the selected IP address range. If it is not a valid IP address, a pro
Synchronization: The concept of object locks. If multiple threads share an object, the operating system generates a lock for each object with one word, and the lock and object one by one correspond. If a thread wants to manipulate an object, it must get the lock on the object.Lock: Synchronous Statement or synchronization method (a synchronous statement is used here). Resolves an interaction thread with tim
This article was reproduced from: http://www.cnblogs.com/youngforever/p/3250270.htmlThese two days to see the process of synchronization and communication, read a few books on the introduction, but also from the Internet search a lot of information, the more confused, the more puzzled by these issues are very tangled.
What is the difference between process synchronization and mutex?
What are the synchronization methods for a process?
What are the communication methods of the pro
Some problems often occur when you operate interface controls or components in multiple threads.
When we operate controls in multiple threads, we generally use the followingCode.
Delegate void msgdel (string Str); protected void msgevent (string Str) {If (txtcontent. invokerequired) {txtcontent. begininvoke (New msgdel (msgevent), STR); return;} txtcontent. TEXT = STR ;}
However, during the debug operation, I still encounter problems such as "cross-thread
