I have a VPN connection set up on my computer. I am trying to make a button in my VB.NET program to connect/disconnect to/from the VPN connection. I have tried making a shortcut to the VPN on my desktop and calling it with the Shell method but I get an error saying file not found. I have also added the shortcut extension ".lnk" and still have the same error.

For an answer to this questions I've been looking years from now, then I couldnt find it and now it's complicated. I am working on a project to fully manage a computer's connection, it can check IP, change it, etc. But, I really, really need a function to sucessfully connect/disconnect a PC from the ineternet without promps or other screens, IPCONFIG and DHCP command aren't useful!, im exploring RAS but couldnt come to anything yet

I am building a chat client/server. And I can connect and chat just fine, but when a user disconnects, the server does not recognize this and acts weird, often spamming the last message that was sent by the user..Also, it's like the client does not disconnect from the server even when I close the client app. Once I exit the program, VB acts like it is still debugging. Once the server is shut down however, I get this error:
IOException was unhandled:Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
serverStream.Read(inStream, 0, buffSize)I don't know how to make my client and server accept the fact that a client has disconnected...
I am currently working on a messenger client that connects to a server then back to the clients for full chat room support.I have it operational however when you close the client before connecting to server it closes normal, if you close the client after you have connected to the server then the client dissapears but it is still running in processes. To make it worse if you close the process it then kills the server.What I need is a disconect button code so it will stop crashing it.Here is my code Client:
Imports System.Net.Sockets
Imports System.Text

I am working on a code for a chat client/server and I have it all working, I can connect and chat locally and global. The problem I am having is that when someone just hits the X in the corner to exit it crashes my server as well as the fact that if someone wants to they can make their username the same as someone elses.
[Code]...
Im using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...
Private Sub getMessage()
For infiniteCounter = 1 To 2
[CODE]...
And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.

Would it be possible to make a webbrowser link to the cookies and such of any windows user account no matter which windows user account you were on. So the user would use a drop down list or something then press a button and be able to switch to another user accounts internet explorer favourites, cookies, and flash cookies, rather than having to log out and then log into another user account?

I have an ADSL connection that requires username password login (PPPoE). This looks just like a phone dial up connection dialog box.But all the codes i've seen for automatically connecting to internet, or even detecting a connection do not work.I'm looking for a way to have my software check for an active connection to internet, and absent that, to connect via the default connection.I'm on XP. I don't know if that makes a difference.I have set properties to save the username password and not to prompt for them. So if I double-click the connection it will connect without any dialog box.

I've came across a little problem with my tcp / ip server. My client can connect to it with 127.0.0.1 ( localhost ), and 192.168.0.X, but every remote connection fails to connect.
Here's the connection rituals:
Server
listener = New System.Net.Sockets.TcpListener(System.Net.IPAddress.Any, Port)
listener.Start()
listenThread = New System.Threading.Thread(AddressOf doListen)
listenThread.IsBackground = True
listenThread.Start()

client = New System.Net.Sockets.TcpClient(IP, Port)
client.GetStream.BeginRead(readBuffer, 0, BYTES_TO_READ, AddressOf DoRead, Nothing)

View 3 RepliesI have a client that wants to connect to his MySQL database using Dial-up/Modem connection. All i know is a phone number. I will be using VB.NET 2005 for this project. We also have a LAN Connection setup to other computer, but some of this computer only uses Dial-up to connect. The LAN connection works fine because i can just use the Local IP to create a connection string.But my problem is how do i get to connect to a remote server using a Dial-up? I know building a connection string require an IP to connect. Do i need to get the IP after a dial-up connection is connected or to i need to use different approach? I have a server and i have 10+ clients, the server has a T1 connection + a dial-up modem installed also.I created a POS system to all the clients, Some clients uses dial-up some uses LAN. What the server do is all the records of the clients POS will be sync to one database on the server in one table. If i'm in the server and and i selected a station/client and click SYNC button all the records on that client will be sync to the server.
View 2 RepliesI am a ASP Classic Programmer, professionally for a little over a year, I have developed some rather nice sites, including the one in my signature (Still a work in progress).
I have been forced to use ASP.NET (VB) for a FileUpload control, as it offers a self controlled way of creating Thumbnails, without the use of 3rd party controls, which is great, as my hosting server does not allow for 3rd party installs on their servers.
So.
The code below is what I have so far for connecting to the database and displaying a record is the "cookie" exist on the users computer.
Unfortunantly, this is not working, and to be honest with you, their is not a whole lot of resources available to show how to do this correctly.
So I am stuck with a lot of post and hoping that someone can actually assist me with this and tell me what I am doing wrong and maybe correct my code.
I am getting an error about the "Connection is closed"
If you want to re-write my code, I prefer something simple and basic, as the only thing that I am doing to checking rather the user is logged in, and if so, display a record from the database. I am NOT in the need for the DataGrid, so please do not suggest it, as I am only needing to check this one thing.
I would like to also add, that I have successfully contect to my database with the FileUpload control and save file names of the images uploaded, so I know that my connection string is done properly> But, for some reason the "SELECT" statement is causing a HUGE issue. (It was easier to insert, than to select, I am not use to that)
CODE:
i connect the Datagridview by using command connection not coding. now i have "table3tableadabter", "table3bindingsource" and "database3dataset" below the form ? the search string " "Select * from tabel3 Where test2 like '" & Me.TextBox1.Text & "%';"" how i can do serch and the result will be shown in datagridview.
