Transmission starts or ends, that is, data communication with the client. If data is transmitted, the ls command also causes data transmission. USERCONTROL_CONNOP_TRANSFEROFFSETS Shows the transmission progress. For example, you need to display the current number of transmitted bytes and transmission rate to the admin window during file transmission. All the information is displayed in the lower half of the admin window. FSM_THREADCANQUIT: These messages are sent whe

In practice, you sometimes need to import a large amount of data into the database and then use it for various program calculations. In this experiment, we will use step 5 to complete this process and record the time spent by various methods in detail. The tools used in this experiment are vs2008, SQL Server 2000, and SQL Server 2008. The methods in step 5 are respectively used to import 1 million pieces of

ArticleDirectory 1. scenario settings 2. Server Module Design 3. Summary The previous blog explains how to implement the IDL parser. This article uses the IDL parser to build a chat server.Program. This program is used to test the function of the IDL parser. The network layer uses the ffown library described in the front blog. We only need to define the chat. IDL file, and the IDL parser automatically generates message emissions.
