Winsock client senddata

Hi everybody,

I have a strange problem.

I using winsock to telnet to some routers.

When I have textbox to send command, senddata works. But when I usind field from database, NO!

There is a script in the attachment!


cmdConnect works!
cmdDisconect works!
But cmdSend NO!



Please help,

Your problem is here:

Code:

---

cmdConnect mtNetwork, mtUsername, mtPassword
cmdSend (Rs.Fields("TaskType1"))
cmdDisconnect

---

Winsock operates asynchronously, that means that control is passed back to your code immediately the SendData has been executed - not when it has actually sent the data - so you're closing the connection before it's had a chance to send the data.

You should use the Winsock_SendComplete event, which is triggered when the data has actually been sent, to close the socket.

You think something like this?

Code:

---

Public Sub cmdDisconnect()
    If WinsockSendFinish = True Then
    Winsock.Close
    End If
    If Winsock.State = sckClosed Then
    WinsockSendFinish = False
    End If
   
While Not WinsockSendFinish
        DoEvents
    Wend
   
End Sub

Public Sub cmdSend(tekst As String)
    broj = 0
    Winsock.SendData Chr(13) & Chr(10)
    Winsock.SendData tekst & Chr(13) & Chr(10)
    WinsockSendFinish = True
End Sub

---

In form_load I put WinsockSendFinish = False

...


And again I have the same problem :(

No, more like this:

Code:

---

Private boSent As Boolean

Private Sub Winsock_SendComplete()
boSent = True
End Sub

Public Sub cmdSend(tekst As String)
    broj = 0
    Winsock.SendData Chr(13) & Chr(10)
    boSent = False
    Winsock.SendData tekst & Chr(13) & Chr(10)
    Do Until boSent = True
        DoEvents
    Loop
    Winsock.Close
End Sub

---

Doogle,

thanks wery much for help!

I'am new in this... :rolleyes:


I replace code and try...

two times do command, and next time no :confused:

I just add to code

Code:

---

Public Sub cmdConfigurationSend()
    Dim ConnectString As String
    ConnectString = Chr$(IAC) & Chr$(DOTEL) & Chr$(ECHO) _
                      & Chr$(IAC) & Chr$(DOTEL) & Chr$(SGA) _
                      & Chr$(IAC) & Chr$(WILLTEL) & Chr$(NAWS) _
                      & Chr$(IAC) & Chr$(WILLTEL) & Chr$(TERMTYPE) _
                      & Chr$(IAC) & Chr$(WILLTEL) & Chr$(TERMSPEED)
    If logovano = False Then Winsock.SendData ConnectString
End Sub

---

And put Sub after connect before login code.

That code I find in project of some Telnet...
If I understood well, this make vt100 terminal..

Now works!!! :thumb:



Thanks again!
