摘要：以实际工程为背景，介绍了在I丑bwindows／CVI环境下，基于ActiveX技术访问Microsoft Excel 2003的方法，以及创建 自动化仪器驱动器的方法。详细阐述了访问Excel具体函数的使用方法，实现了对Excel的访问。通过该工程实例，说明 了本方法具有重要的工程实用价值。(Abstract：The approach of accessing to Microsoft Excel 2003 based on ActiveX technology in LabWindows／CVI environment is intrt~ uced，in 8cN~ence，the establishments of driving scheme for automatic instruments are presented in detail．To realize the access to Excel，the operations of accessing to the real functions are intensively illustrated as wel1．Th e experiments in the real environment demonstrate that this method illustrated here is of great value for practical applications．)

利用labview操作者框架写的模拟串口通信，非常不错。(The analog serial communication written by the labview operator framework is very good.)

采用虚拟仪器LabWindows/CVI软件平台开发了基于PCI-6221多功能数据采集卡的实时频谱分析仪。(Virtual instrument LabWindows/CVI software platform based on real-time spectrum PCI-6221 multifunction data acquisition card analyzer.)

基于labview的TCP客户端程序发送主机通常将发送缓冲区中的数据按内存地址从低到?的顺序发出,接收主机把从?络上接到的字节依次保存在接收缓冲区中,也是按内存地址从低到?的顺序保存。 TCP/IP协议规定,?络数据流应采??端字节序,即低地址?字节。 socket API是?层抽象的?络编程接?,适?于各种底层?络协议,如IPv4、 IPv6,以及后?要讲的UNIX Domain Socket。(Based on the TCP client program to send the host LabVIEW will usually send buffer according to the data in the memory address from low to order issued, the receiving host to receive from the network bytes on sequentially stored in the receive buffer, and according to the memory address from low to preservation order. The TCP/IP agreement, network data flow should be endian, low byte address. Socket API is layer abstract network programming interface, suitable in various underlying network protocol, such as IPv4, IPv6, and UNIX Domain Socket to say.)
