Telnet looping in timers
I'm writting some code for a school project now to telnet to webservers using winsock to see if a particular page is there using the GET command. The user clicks a button and it tries different urls when connected. I'm having trouble with it, I can't get the program to request other files after the first. I have set the code up in a timer and got a run time 40006 error "wrong protocol or connection state", where I have commented:
---------begin code--------------------
Private Sub tmrURL2_Timer()
If (winsck.State <> 0) Then
winsck.Close
End If
winsck.RemoteHost = CStr(HOST)
winsck.RemotePort = 80
winsck.Connect
Dim string_to_send As String
string_to_send = "GET /whatever.html" 'change right here for string
If (winsck.State = 0) Then
func.send_to_buffer ("You need to connect first!")
txtCMD.Text = ""
Else
If (string_to_send <> "") Then
winsck.SendData string_to_send & vbCrLf
'the above line is where I receive the error
func.send_to_buffer_norm (txtCMD.Text)
txtCMD.Text = ""
txtCMD.SetFocus
Else
func.send_to_buffer ("Nothing to send!")
txtCMD.Text = ""
txtCMD.SetFocus
End If
End If
End Sub
-----------end code insert------------------
If there is a better way to set this up without the use of so many timers, I would like to know. Please let me know how I can work around that error also. Thanks in advance, dissoluten.
