vb.net当中如何才能使用mscomm32.ocx和MSWINSCK.OCX？

[kw123]

为什么我增加MSCOMM32.OCX的时候，系统提示：不兼容....，无法增加？

我怎样才能使用MSCOMM32.OCX组件呢？

同样，如何才能在VS。NET中使用串口控件！！！

[supershagua]

安装VB6里面的activeX控件就可以了

[wangchong]

1,安装VB6
2,添加引用。
但版本高的操作系统好像不是很稳定！！

[kw123]

好象不行啊！

[tanzsf]

最好别用,我用过发现不太稳定,有一些错误在程序中会捕捉不到

[kw123]

不行，重新回答！！！
