Ignore, resolved the problem Why would a WebRequest return data that is hours out of date? Do I have to set something to ensure that it's not looking at cached information. It worked so well yesterday, and today it's hopeless...

I build an app and i want it to block surfing when a "user" didn't chose, but I can�t find a way to stop the network adapter from c#. I saw and tried a lot of examples and advices from all other the net, but none worked for me. I tried to disabled the adapter- public void DisableNetWork(string interfaceName) { SelectQuery wmiQuery = new SelectQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionId != NULL"); ManagementObjectSearcher searchProcedure = new ManagementObjectSearcher(wmiQuery); foreach (ManagementObject item in searchProcedure.Get()) { if (((string)item["NetConnectionId"]) …

My application uses httpwebrequest class to access a secured service. I have received a certificate which I installed on the pc. the web service requires a username and password. I get the following message when running the app: "The underlying connection was closed. Could not establish trust relationship for the SSL/TLS secure channel" My code is below but I don't know what is wrong or what else to do. Thanks.

I have a service that uses the tcpClient to send and receive data. I can unplug the network cable and the service does not know the connection has been broken. This is the code that is used to test the connection. The call to send does not throw an error. How can I get my service to know the connection has broken? Any help is greatly appreciated. Private Function IsConnected() As Boolean SyncLock (_sendSyncObject) If Not _tcpClient Is Nothing Then Try If IsConnectionInCloseWait() Then Return False Dim data(0) as byte _tcpClient.Client.Blocking = False _tcpClient.Client…

IIS hosted WCF service does not work Hi all: I am trying to learn WCF. I have tried serveral examples from the Web which do not work as they were instructed for me. I must be doing something wrong but am not sure what. I have windows 7 home, VS2012. I created a solution call Greetings. In the service I added a class Library where I put the Interface and Service class. To that solution I added a website using the wcf service template type. I added the reference to th greeting class library that has my interface and service class. This is supposed to be hosted by IIS. I wrote a client app to access the service but the error tells me there no service at the endpo…

I am trying to learn how to write a web client. I wrote a WCF web client to the same site in the code below and that worked. I would also like to write one similar to the code below. Any ideas on what I am doing wrong would be great. I am getting the error: InnerException = {"Content-Length or Chunked Encoding cannot be set for an operation that does not write data."} Public Class Form1 Dim manualWebClient As New System.Net.WebClient() Private Sub Jack() Handles Button1.Click manualWebClient.Headers.Add("Content-Type", "text/xml; charset=utf-8") manualWebClient.BaseAddress = "http://ws.cdyne.com" Dim reqstr As String = "<s11:Envelope xmlns…

Hi all: I have been given a set of schemas and wsdl. I have to write an application that will submit a request to a service and get a response. I don't even know where to begin. Can someone tell me What type of service I am writing and some of the things I may need to do to make use of the schemas and wsdl to make a valid request? I hope this is even enough info for someone to give me some direction of what I can do to start. Please excuse my ignorance. Thanks.

Hi everyone, Following is the callback method that I use in my socket programming at client side for async receiving of data from server:- Public Sub OnDataRecieved(ByVal async As IAsyncResult) Dim Recieved_Size As Integer = m_clientSocket.EndReceive(async) ...........(rest of the code) End Sub What my doubt is that when "Recieved_Size" = 0, should I conclude that the socket has got disconnected? If not, then under what cases should Recieved_Size be = 0 ? Why I am asking is that whenever the connected server gets disconnected then "OnDataRecieved" method gets called and the resulting "Recieved_Size" is = 0. But it should be called only whe…

Hello, I am using visual basic 2005. I found on the web the following function that extracts HTML from webpages. It is very useful but unfortunately it does not work with redirected pages. That is, when I put in it a URL of a redirect page it gives me nothing or error. I added to it ".AllowAutoRedirect = True" but still it did not work. I wonder how to make it work for redirected pages. I appreciate the help. Public Function GetPageHTML(ByVal URL As String, _ Optional ByVal TimeoutSeconds As Integer = 10) _ As String ' Retrieves the HTML from the specified URL, ' using a default timeout of 10 seconds Dim objRequest As Net.HttpWebRequ…

Hello , Please bear in mind that im not an experts, and my knowledge hardly exceeds what google search results has to offer a noob. i have a multi-client server application, for video conferencing, and everything works good untill more than 4 or 5 users connects to the server.

Client Connection Code VideoSoc = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); int Videoport = 8003; IPAddress server_ip = IPAddress.Parse(textBox1.Text); IPEndPoint ConnEndPoi…

This one seems to be pretty weird. I'm using asynch TCP sockets in my program. I have one class called ConnectionManager (implemented on the server machine), which has this NetMain event running on its own thread: Private Shared Sub NetMain() Dim TcpListen As TcpListener = New TcpListener(m_ListenPoint) Try TcpListen.Start() Catch ex As Exception RaiseEvent Exception(ex) End Try ServerGroup = New EthServerPool() Do If (TcpListen.Pending) Then If (ServerGroup.UpperBound < m_MaxClients) Then ServerGroup.AddSock…
