VS 2008 DNS.gethostentry Error ' No Such Host Is Known'
Sep 3, 2010I have been trying to trace a list of urls by using the url to get the ip and then use that to assign it a country. When using DNS.gethostentry or even DNS.gethostbyname I get the following error:
SocketExceptionwascaught: No such host is known
Now I even tried fetching the url first using httpwebrequest to ensure the url is valid but the error keeps showing up regardless. I know there are a few urls that don't work but I thought my code would catch and continue.

Error: 0 - An Existing Connection Was Forcibly Closed By The Remote Host
May 19, 2012Below error is thrown in a already opened program which connects to different database
A transport-level error has occurred when sending the request to the server.
(provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
Program details: code done using vb.net with MSSQL 2008 as back-end
Two instance of same exe where running simultaneously in same PC but error was thrown only by one instance Program uses both sqlconnection(ADO.NET) and ADODB connection(upgraded from VB6) and the error is thrown by both types of connection. If the error is due to network problem with the server then why few programs work fine? I am not able to trace the reason for this behavior of the program. Can I know why this error occurs and why only in few programs of same instance.

View 3 RepliesC# - Get The Host Out Of The Request Object?
Aug 3, 2009I need to get the host out of the Request object. Which property should I use and why?
From MSDN:Uri.DnsSafeHost Property A String that contains the unescaped host part of the URI that is suitable for DNS resolution; or the original unescaped host string, if it is already suitable for resolution.
vs
Uri.Host Property A String that contains the host name. This is usually the DNS host name or IP address of the server.
My testing has been with the ASP.NET Development Server. Both of these always return localhost. Even when I put in 127.0.0.1, both return localhost.Reading on, the DnsSafeHost property will handle IPv6 addresses, as well as Unicode to ASCII conversion if needed. It can also account for IRI and IDN. Even though I currently don't care about these things, should I just use the DnsSafeHost property to be safe?
Cannot Copy VWD Files To Host
Aug 25, 2009In my ignorance, I thought I could subscribe to any host, so I chose hostmonster, and copy files from Visual Web Developer to it, thereby creating my first website. Wrong! Hostmonster is linux-based, so the files won't copy without assigning an index page at the site. The rep at the host said that linux doesn't read the language(s) I've been using to develop pages, Visual Basic and C#.

Host Forms In On-form Web Browser?
Sep 30, 2009I've done simple preliminary research without success--I'm posting now simply because time is an issue. I wanted to see if I could use the on-form web browser to pull up forms not on the server or internet, but locally hosted in the solution. Based on what the user selects in a combo box, I need certain parameters (any 5 are relevant out of approx 100 total). I was hoping to do this without a button--pulling up a form with command button is a last resort. Is this possible?
