hi Dejan,
Thanks for answering my query...
Tried using this code in local ;and gave 'yahoo' for checking.
Please see the output i got
yahoo.com

No match for "YAHOO.COM".
A lso I understood Request.Form["WhoisServer"] gives the hostname in the hostname dropdownlist.
Why we need to use Request.Form.?Why not to use WhoisServer.SelectedValue. / DomainName.Text?
The values I gave for WhoisServer are whois.networksolutions.com (.COM, .NET, .EDU),
whois.ripe.net(Europe),whois.cira.ca (.CA),whois.nic.uk(.CO.UK),whois.domain-registry.nl(.NL).
But when I uploaded this page and checked online i didnt get any response. So I changed the value for TcpClient and gave as
- TcpClient objTCPC = new TcpClient(ddlWhoIs.SelectedValue,43);
Then also no respnse..
Again I gave as
didnt select hostname value from dropdown box.
System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond at
System.Net.Sockets.TcpClient.Connect(String hostname, Int32 port) at System.Net.Sockets.TcpClient..ctor(String hostname, Int32 port) at Reach.domain.btnAvailable_Click(Object sender, EventArgs e) in c:inetpubwwwrootOSDTestdomain.aspx.cs:line 61
Since I want to use this code in my project i dont want my client to see the terms and conditions.
Only need to know its available or not.
Hope I am not confusing you.
Please make me clear my doubts.
Regards,
Reshmy.
