Question

我正在尝试使用以下代码处理Winsock_Connect事件（实际上我需要在Excel宏中使用它）：

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

但它永远不会进入Winsock1_Connect子程序，尽管Winsock1.State是“已连接”。我想使用标准MS库，因为我的PC上没有管理权限，我无法注册一些自定义库。任何人都可以告诉我，我错了吗？

Answer 1

你是否坚持使用MSWinsock？
Here是使用自定义winsock对象的网站/教程。

另外......你需要在“Class”模块中声明Winsock1 WithEvents ：

Private WithEvents Winsock1 As Winsock

最后，请确保引用winsock ocx控件工具 - ＆gt;参考文献 - ＆gt;浏览 - ＆gt; ％SYSEM％\ MSWINSCK.OCX

我在VBscript中使用事件处理的简短示例：

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!
