Call to Server with HttpWebRequestClass before logged on to windows

[tobeki]

Hi guys,

i hope you can help me with my head-against-the-wall-bouncing-problem. First the scenario:

winlogon.exe (with customized GINA) calls a win32-DLL which calls to my C++-DLL (ummaged C / managed C++ bridge), which references my HttpWebRequest-C#-DLL which calls the Http-Server-address.

If i run my HttpWebRequest class standalone from a testApp.exe, AFTER windows logon, to call the remote Http-Server it works. But if try to call the server (above described scenario) BEFORE logged on to windows this creation fails with a System.Configuration.ConfigurationErrorsException:

HttpWebRequest req = new (HttpWebRequest) WebRequest.Create(server-uri);

My HttpWebRequest-C#-DLL does not lie in the winlogon.exe (system32) application folder, but it is referenceable via GAC. Is this a permission problem with machine.config ? How can i fix it ? Can i provide an app.config to my C#-DLL with permission settings to allow the Http-Server-Call?

Thanks in advance and
greatings from Bavaria

The exception in detail:
"The configuration system could not be initialized.."

Says you have illegal characters.
Your locale (language/keyboard/etc) settings are stored on a per user basis.
So if you're not logged on as a user, you're getting the system default local, which could possibly be en-US and not have the characters you are after

thanks for your reply!
so you think that in system internal use the url parameter is not interpreted as e.g. http://192.168.2.4:8181/CustomerServer/servicename, but as (EN locale) http>&&192.168.2.4>8181&CustomerServer&servicename ?
the test messagebox shows the url with correct special characters.. but i am not able to debug this from GINA. maybe you are right.
For testing.. is there a way to set the locale to a fixed locale (en or ger) programmatically before i call the HttpWebRequest / WebClient class ?

The developer system is a Windows Server 2003 (en) with VS2008 (en). The test machine (the windows-client i get the exception) runs on a XP Professional (ger)

Yes that def sounds like a language setting issue.
I think if you look up globalization and Culture settings you should find help on it.
I've never done it myself so I cannot be sure.

ok i have tested the "locale-case". It is not the problem. But this code of line

Uri url = new Uri("www.googe.com");

called from Windows GINA, before logged on to windows does show a bluescreen.

I seems to me that some System.Net classes, neccessary for http-communication, are not initialized yet (at this moment).. :(

Problem solved without System.Net.
