standard. So. NET platform provides a common language framework that is of great benefit to scripting writers. Osborn: We've talked about Java, C + +, and scripts. At pdc[: [Microsoft] Professional Developer Conference] I hear a lot of people arguing. NET Il (il is the Microsoft intermediate language, all compilers must produce it to run in. NET Framework) and Java bytecode running in Java virtual machines are no different. From your conversation, obviously you don't agree with that. Would yo

Today we will share with you a beautiful and flexible vertical jQuery accordion effect. The main idea is to expand click and display more information on the accordion. If you are interested, refer to the following Section. The jQuery-Based Multi-Level accordion is a beautifying multi-level accordion special effect code.

Exception trapping in C # I believe everyone is familiar with the common use of exception captures are: 1. try{...} catch (Exception ex) {throw ex;} 2. try{...} catch (Exception) {throw;} 3. try{...} catch (Exception ex) {throw new Exception ("Exception description", ex); I believe we are all familiar with these 3 kind

, there is always an unexpected exception thrown, which is a good practice to capture exception directly.Scenario: When the client invokes the WCF service, we all need to do exception handling at the customer, the most common error exception for the communicationexception,timeoutexception,exception example is as follows:Try { //Execute method call ......

)] can be used to make an application into a single instance. Windows applications load the form using the application. Run () method. In the main method, create a new mutex. If you can create a new mutex, the application is allowed to run. If mutex has been created, the application will not start. This ensures that only one instance is running for any use. // Checks whether a new mutex is created.Bool newmutexcreated = false;// The mutex name is prefixed with local,// Make sure that it is crea
