MSWinsock.Winsock事件的VisualBasic处理(MSWinsock.Winsoc

2019-07-31 22:41发布

我尝试使用下面的代码来处理Winsock_Connect事件(其实我需要它在Excel宏):

Dim Winsock1 As Winsock 'Object type definition

Sub Init()
    Set Winsock1 = CreateObject("MSWinsock.Winsock") 'Object initialization
    Winsock1.RemoteHost = "MyHost"
    Winsock1.RemotePort = "22"
    Winsock1.Connect

    Do While (Winsock1.State <> sckConnected)
        Sleep 200
    Loop
End Sub

'Callback handler
Private Sub Winsock1_Connect()
    MsgBox "Winsock1::Connect"
End Sub

但它永远不会尽管Winsock1.State“连接”到Winsock1_Connect子程序。 我想使用标准的MS库,因为我没有在我的电脑上的管理权限,我不能够注册一些自定义库。 谁能告诉我,我哪里错了?

Answer 1:

您是否使用MSWinsock卡住?
下面是使用自定义的Winsock对象的位置/教程。

还...你需要一个“类”模块中声明为Winsock1 WITHEVENTS:

Private WithEvents Winsock1 As Winsock

最后,请确保您引用winsock的ocx控件。

Answer 2:

文档关于Winsock控件
http://msdn.microsoft.com/en-us/library/aa228119%28v=vs.60%29.aspx
这里的例子:

我简单的例子与在VBScript事件处理:

Dim sock
Set sock = WScript.CreateObject("MSWinsock.Winsock","sock_")
sock.RemoteHost = "www.yandex.com"
sock.RemotePort = "80"
sock.Connect

Dim received
received = 0

Sub sock_Connect()
    WScript.Echo "[sock] Connection Successful!"
    sock.SendData "GET / HTTP/1.1"& vbCrLf & "Host: " & sock.RemoteHost  & vbCrLf & vbCrLf
End Sub

Sub sock_Close()
    WScript.Echo "[sock] Connection closed!"
End Sub

Sub sock_DataArrival(Byval b)
    Dim data
    sock.GetData data, vbString
    received = received + b
    WScript.Echo "---------------------------------------"
    WScript.Echo " Bytes received: " & b  & " ( Total: " & received & " )"
    WScript.Echo "---------------------------------------"
    WScript.Echo data
End Sub

'Wait for server close connection
Do While sock.State <> 8
    rem WScript.Echo sock.State
    WScript.Sleep 1000
Loop

输出将是:

cscript /nologo sockhttp.vbs

[sock] Connection Successful!
-------------------------------
 Bytes received: 1376 ( Total: 1376 )
