为什么在VB.NET 中的AxWinsock1.SendData(TextBox2.Text)和AxWinsock1.GetData(strData)发送和接收都会出现错误的?
源码如下:
接收:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
AxWinsock1.SendData(TextBox2.Text)
Catch OE As System.Runtime.InteropServices.COMException
End Try

End Sub
发送:
Private Sub AxWinsock1_DataArrival(ByVal sender As Object, ByVal e As AxMSWinsockLib.DMSWinsockControlEvents_DataArrivalEvent) Handles AxWinsock1.DataArrival
Dim strData As Object
AxWinsock1.GetData(strData)
TextBox1.Text = strData
End Sub

没有人知道的吗?

当然连接了的,发送信息只是执行Catch OE As System.Runtime.InteropServices.COMException而已,如果没有这句就会出现COM错误了.

如果没有这句Catch OE As System.Runtime.InteropServices.COMException,执行到发送AxWinsock1.SendData(TextBox2.Text)
这句时会提示这个错误:
未处理COMException
所需事物或请求的错误协议或连接状态
检查异常的ErrorCode属性以确定COM对象返回的HRESULT
