摘 要 VB是一种可视化的、面向对象和采用事件驱动方式的结构化高级程序设计语言，可用于开发Windows环境下的各类应用程序。在Visual Basic环境下，利用事件驱动的编程机制、新颖易用的可视化设计工具，使用Windows内部的广泛应用程序接口（API）函数，以用动态链接库（DLL）、对象的链接与世隔嵌入（OLE）、开放式数据连接（ODBC）等技术，可以高效、快速地开发Windows环境下功能强大、图形界面丰富的应用软件系统。为了提高数据吞吐率以及实现实时数据处理(如随时取数、随时暂停设备、随时开始传输、随时存盘、随时显示波形、随时设备控制输出等功能), 我们采用一种必威体育精装版、最灵活的设计思想，即数据采集传输和数据处理相独立的思想TCP/IP应用程序的开发，winsock套接字以及winsock通信等问题。 关键词：VB 数据处理 网络系统 网管软件 Abstract VB is a visual, object-oriented event-driven approach and the use of the structure of high-level programming language, can be used for the development of the Windows environment of various applications. In Visual Basic environment, the use of event-driven programming mechanism, the new easy-to-use visual design tools, within the wider use Windows application program interface (API) function, to use dynamic link library (DLL), the object Links embedded with the World at (OLE), open-end data connectivity (ODBC), and other technology, can be highly efficient and rapid development of the Windows environment powerful, rich graphical interface application software system.  In order to improve data throughput and real-time data processing (for example, at any time from the number of suspended equipment at any time, at any time beginning transmission, archiving at any time, at any time display waveform, at any time equipment control output, and other functions), we have adopted a latest and most flexible design thinking That the transmission of data acquisition and data processing of independent thinking  VB-based network management systems, drainage network for the network system management, from data collection and network management system functions, complete network management software design, research TCP / IP application development, winsock socket and winsock communications issue.
