越来越觉得自己不是搞技术的料了，搞点小东西都觉得力不从心啊！说到这，真的很佩服电脑圈圈和匠人，05年跟圈圈吃过饭，那时正要毕业，是去他那边寻求帮助的。虽然没见过匠人，但看他的博客，不得不佩服啊！尽力搞的，反正也不是工作，只是业余的，能学好就开心了，压力没那么大！

今晚从8点搞到现在，从写了一个最简单的软件，简单到自己都不好意思，不管怎样，起码成功了第一步

这是VB写的界面，够简单吧

这个是51TCP板发数据给VB接收后的图，TCP板发送字符16000

下面是VB代码，先发上来，以后还要接着改，习惯不好，都没写些注释，呵呵，大家见谅！

End Sub

Private Sub sock_Close(Index As Integer)

End Sub

Private Sub sock_ConnectionRequest(Index As Integer, ByVal requestID As Long)
