MSComm控件资料,Visual Basic 6.0(以下简称VB) 是一种功能强大、简单易学的程序设计语言。它不但保留了原先Basic语言的全部功能，而且还增加了面向对象程序设计功能。它不仅可以方便快捷地编制适用于数据处理、多媒体等方面的程序，而且利用ActiveX控件MSComm还能十分方便地开发出使用计算机串口的计算机通信程序。本文结合计算机通信的两个例子，详细介绍如何在VB中使用MSComm控件。 处理方式 -MSComm information, Visual Basic 6.0 (VB hereinafter) is a powerful, relatively simple programming language. It not only retains the original Basic language functionality, but also an increase of object-oriented programming design functions. It will not only facilitate the efficient preparation of the application to data processing, multimedia and other aspects of the procedure, and the use of MSComm ActiveX control can be very convenient to use the computer to develop the computer serial port Communication Program. Based on computer communication, the two examples in detail how to use VB MSComm. Approach
