如果是使用WINSOCK进行TCP连接连接后如何发送16进制数据包？

最好就是让对方发送一个反馈包然后发送下一个或者定义一个数据包的结构,在包头存放标签,数据大小等然后放数据最后发包过去（我自己做的加了MD5验证）'这是接收数据的winsock'Execute函数是处理数据的:Private Function Execute(ID As Integer, b() As Byte, ret As Boolean) As Byte()'ret是是否返回发送一个数据包，b()是数据，ID是winsock的index（这是支持多sock的）Private Sub wsi_DataArrival(Index As Integer, ByVal bytesTotal As Long)'Debug.Print bytesTotal'If bytesTotal = 2 Then Stop'Debug.Print UBound(buff(bi).b)If bytesTotal <= 0 Then Exit SubDim bi As Integer, br As Long, kh As kHeader, kf As kFooterbi = FindIDBuff(Index + 1)If bi = -1 Thenbi = NewBuffindexbuff(bi).ID = Index + 1Dim t() As ByteReDim t(LenB(kh) -
