Question

Method 'SendData' of object 'IMSWinsockControl' failed

Asked by: jbrugman

Hi.

I use a std. class module winsock.cls (from hector), together with the reference to MSWINSCK.OCX

Now i've written a client with the following code,
ps. the error i get is the same as the question,
when i first start the connection in another function, like in loading the form, it works fine.
At inserting a doevents, it works one time, using sleep doesn't make a difference.

Any ideas?
code:
On Error GoTo errorhandler
    Dim ip As String
    ip = "127.0.0.1"
   
    ' Make the connection to the server.
    If (myTCPClient.TCPClient.state <> 0) Then myTCPClient.TCPClient.SocketClose
    Call myTCPClient.TCPClient.ClientConnect(ip, 1001)
    If myTCPClient.TCPClient.state = 6 Then Form1.Text1.Text = "open..."
   
    ' DoEvents
   
    ' Send the data to the server.
    myTCPClient.TCPClient.SendData sfile + vbCrLf
   
    myTCPClient.TCPClient.SocketClose
   
errorhandler:
Debug.Print (Err.Description)

Hi!

I've got no idea about the Winsock coding with the winsock API, but, why not use the winsock control instead?  It's easier to code with it.

Anyway, here's another winsock API link for you in case the problem lies with the class after all:

A tutorial:

Description: This program will teach you how to use the winsock api's. I made this easy to understand so that anybody can use it. even beginers! isn't that crazy? *fixed, with subclassing function now!* if you like this, please vote for me! thanks!
 
An example:

http://www.planetsourcecode.com/vb/scripts/ShowZip.asp?lngWId=1&lngCodeId=25603&strZipAccessCode=hatB256037872
Description: This is a great chat program that doesn't uses MsWinsock control, just API calls! It has an INI for remmembering options, home made buttons and you can add it to your systray when you don't need it (msgs from peer will popup in a very clever way). It also includes 1 simple back door (open any program on peer) (I strongly advise you to deactivated, to do so comment the !run commands in the General.Bas). Thanx to your feed back i've already...


That's it!

I alreaddy found the answer.
Winsock api can not be used, becouse in some cases it deletes / corrupts your stack, and even the following solution will not work then.

Ps. winsock also uses a form, and for an activex dll, i have no use for them.

Anyway, for the record:

    ' Open the connection to the server.
    Do While (myTCPClient.TCPClient.State <> sckClosed)
        DoEvents
    Loop
    myTCPClient.TCPClient.Connect "127.0.0.1", 1001
   
    ' Wait fot the server response.
    Do While (myTCPClient.TCPClient.State <> sckConnected)
        DoEvents
    Loop
   
    ' Send the document to the server.
    myTCPClient.TCPClient.SendData theData
