Basic concepts of Events-Beginning Visual C #, A trigger condition is required for an event, such as timed occurrence, Mouse clicking, and the event itself. Therefore, the simplest events-related example is as follows: // Time trigger class TimerTrigger {private Timer myTimer; public TimerTrigger () {myTimer = new Timer (100);} public TimerTrigger (int timeInterval) {myTimer = new Timer (timeInterval);} //

In fact, using Visual Basic ActiveX exe technology can easily implement multithreading.Let's not talk about the principle. Let's give an example. If you are interested, you can discuss it together.1. Create a new project, select ActiveX Exe as the type, and rename the project to TestExe.Add a Form in the project and put a Timer control.Rename Class1 to clsTest. Note that its Instancing must be set to 5-Mult

In fact, using the ActiveX EXE Technology of Visual Basic can easily achieve multithreading. The principle is not to say first, to give an example, if interested, we can discuss together 1. A new project, type selection ActiveX Exe, project renamed to Testexe Add a form to the project and put a timer control on it. Rename Class1 to Clstest, note that its instancing to be set to 5-multiuse, the following is

server encounters a dynamic program, it can be delivered directly to the fastcgi process to execute, and the resulting results are returned to the browser. This approach allows HTTP servers to handle static requests in a single-minded manner or to return the results of a dynamic script server to the client, which greatly improves the performance of the entire application system.Nginx does not support direct parsing of external programs, all external

Tutorial on the basic usage of Regular Expressions in Ruby programs, ruby Regular Expressions Most of Ruby's built-in types are similar to other programming languages. Mainly include strings, integers, floats, and arrays. However, only script languages such as Ruby, Perl, and awk provide support for built-in expression types. Although the regular expression is relatively hidden, it is a powerful text proces
