vb.net从一台主机通过socket同时向多台主机传送信息，如何操作？

用VB5 Winsock控件创建TCP/IP通讯程序随着Windows 95中文版和Windows NT Server 4.0中文版的流行， Microsoft公司推出了相应平台上的开发软件: Visual Basic 5.0 中文企业版。它为Windows环境下的网络开发提供了强大的工具，Winsock控件就是其中之一。 Winsock控件建立在TCP、UDP协议的基础上，完成与远程计算机的通信。即使对TCP/IP不太熟悉的用户，使用该控件也可以在十几分钟内创建一个简单的客户机/服务器程序。下面我们对Winsock控件的事件、方法、属性按其在程序中出现的顺序分别作详细的介绍，以便更好地理解程序源代码。

vb.net中SendMessager的问题

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As String, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long

改为

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As String, ByVal wMsg As integer, ByVal wParam As integer , ByVal lParam As String) As integer

再试试VB.NET发短信，

可能你VB.NET发短信的声明使用vb6。0 复制过来VB.NET发短信的VB.NET发短信，long 全部改成integer
