I'm currently making a code that will login to a cisco router, and show the version, then return the version to me. The connection to the cisco router is using telnet, and I'm using Dimac's w3Sockets code to Connect, login, and return data. Reference
But currently I'm having some problems, since the router sometimes need the login typed 2 times, or having a key pressed to update the terminal(telnet),meaning i have to check if it gets logged in or not. But the problem is that using dimac code, i can only wait() and waitFor(), and if it none data comes whilst waiting, it keeps on waiting. Is there away to do like: "if wait fails goto"
I've tryed "on error goto", but since its not a error, but just keeps waiting, that dont work. Also, To locate where it gets stuck I have it write to my textbox everytime it takes a step in the code, but its like the dimac code overtakes vb.net. ex: If i send some text to a textbox in the same sub as the connect code is, and it gets stuck at a wait, it dont even write to the textbox, eventhough the textbox.text command was suppose to execute before the wait().
Code:
Private Sub telnet(ByVal port)
TextBox3.Text = TextBox3.Text & Environment.NewLine & "Telnet func Called" 'Cant execute this if it gets stuck at login below. ??

I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.

I have an sql database with multiple tables. I have been adding new columns to one of the tables as I need them, but now suddenly it has stopped allowing me to add columns.Everything works as usual until I add the 150th column to the table. When I drag the table from the server explorer to the dataset designer i get the following error:"Some updating commands could not be generated automatically. The database returned the following error: Dynamic SQL generation is not supported against a SelectCommand that does not return any base table information.If I remove the 150th column, everything works great. I tried using the wizard to regenerate the select and update statements, but it fails with the same error.

i was used to be vb 6.0. but now im starting with vb 2010 because 6.0 is old. but now i have a few problems with converting some things for my game that im making.
in 6.0 it was
modPlayer (module)
Public Player(1 To MAX_PLAYERS) as PlayerRec
Private Type PlayerRec
Name as string
Level as string
End Type
but this code gives in 2010 some errors; it says it should be structures right now?
Module modPlayerRec
Public Player(0 To 100) As PlayerRec
Structure PlayerRec
Public Name As String
End Structure
End Module
what should be the right code for vb 2010? this is not working what i have right now.
