.NET Forum / .NET Framework / New Users / August 2004MSSupport: Compact Framework connection issue
"Unable to read data from the transport connection" error received when trying to connect to a website through a firewall that requires a username, password, and domain. The code works from behind firewalls that don't require domains. The customer can connect to the website in Pocket Internet Explorer. A dialog comes up that asks for user, password, and domain. How can we get this dialog to come up in our VB .NET application? Windows Mobile 2003 SE operating system Here is the code: myRequest = System.Net.WebRequest.Create(RsURL) myRequest.Timeout = 30000 myProxy = New System.Net.WebProxy myUri = New Uri(Utils.GetOption(cmd, "ProxyServer")) ' Associate the new Uri object to the myProxy object. myProxy.Address = myUri sProxyUser = Utils.GetOption(cmd, "ProxyUser") sProxyDomain = Utils.GetOption(cmd, "ProxyDomain") myNetworkCred = New System.Net.NetworkCredential(sProxyUser, Utils.GetOption(cmd, "ProxyPwd"), sProxyDomain) myProxy.Credentials = myNetworkCred myRequest.Credentials = myNetworkCred myRequest.Proxy = myProxy Hi Mike, The dialog is popped up by IE, we can not make it show in the program. Do you mean just the Firewall need authentication or both the website and the firewall need authentication? If both need, then the program works when both authentication without domain or just one of them? Also I think you may try to specified the username with format as below in the NetworkCredential to see if that works domainname\username Best regards, Peter Huang Microsoft Online Partner Support  SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Why can't a VB .NET app make the same dialog popup that IE has? Isn't VB .NET one of the premier application development tools for Windows Mobile? That's why I chose it. Can C# make it popup? Just the firewall needs authentication. Their firewall may use "Window Integrated Authentication" which I understand v1 of the .NET Compact Framework doesn't support. Where can I get v2 Beta of the .NET CF? > Hi Mike, > [quoted text clipped - 13 lines] > Peter Huang > Microsoft Online Partner Support Hi Mike, I am sorry if I make any confusion. I mean the dialog is popped up by IE and handled by IE, i.e. when the IE get the 407 response, it will popup the dialog and then collect the username and password to resend the request. But we can not popped up such dialog in out windows application, the dialog I mean here is that the dialog popped up and we input user/pass and then the system will pass the credential automatically. But in windows application we can do the same job, e.g. we can run in the try ...catch , when the security exception occur, we can pop up a dialog and collect the usr/pass and then pass it to the request( here we need to handle the credential transportation ourselves), so here we do not need to popup such dialog, what we need to do is how to send the correct credentials. For compact formwork 2.0 issue, here is some information. In addition, Microsoft highlighted great momentum around the .NET Compact Framework. Version 2.0 is included in the beta release of Visual Studio?2005, the next major version of Visual Studio being released at the conference. Microsoft .NET Compact Framework 2.0 provides a richer application development environment for mobile developers through dramatically increased productivity, performance and extensibility. In addition, the .NET Compact Framework partner roster continues to grow, and Microsoft has received positive feedback from smart device application builders and customers that have benefited from the combination of the familiar Visual Studio development environment and the .NET Compact Framework. One customer that has experienced cost reductions and increased productivity benefits from this combination of tools is the global logistics company TNT Express. The company recently used the .NET Compact Framework to develop a field force remote management application, which was deployed to more than 24,000 of its employees around the world. The use of .NET Compact Framework enabled TNT Express's existing base of developers to build the application with reduced costs and time to market. http://www.microsoft.com/presspass/press/2004/jun04/06-29MobileDevTechEdWith O2PR.asp We may get the vs 2005 beta release here. http://lab.msdn.microsoft.com/vs2005/ Best regards, Peter Huang Microsoft Online Partner Support SignatureGet Secure! - www.microsoft.com/security This posting is provided "AS IS" with no warranties, and confers no rights. Thanks Peter. Are you located in China? I notice that your posts are always at night by U.S. time. Hi Mike, Yes, you are right. So there is a few hours' time difference. Anyway, if you have any problem, please feel free to post here.
