谁能给一个运用MSComm控件的实例，主要功能就是给一个串口发送一个数据（只发送就行）
邮箱：445763455@qq.com
最好是用VC编的一个窗口程序，不是MFC~
如果回答得好帮我解决问题了还追加分呐！
最好是能给我一个完整的工程，能让我直接运行的，而不是把主要代码贴上来。
我自己找到了一个叫MSComm控件的视频，但他是用在MFC上的，我在自己用VC写的窗口函数上运用MSComm控件就出现了一些问题，比如添加MSComm控件时说“不支持此接口”谁能帮忙解决下啊？

Answer 1

楼上 发过了，我这里就 免了

不贵，推荐 书籍

Visual C++_Turbo C串口通信编程实践

Answer 2

已发送,请查收.

其中能执行的是\第1章 串口编程调试精灵\Debug\CommWizard.EXE
文件.
