How can I call the windows authentication window from C# code?

Posted By:      Posted Date: October 14, 2010    Points: 0   Category :.NET Framework
 

Hi,

To begin with: I DO NOT WANT A SOLUTION FOR ASP.NET

 

I have a windows application which tries to get information from the internet. But the connection to the internet can only be established through a proxy server.

Normally, the users who use the application log in with their credentials and that should automatically connect to the proxy server. But, for example, when you try opening Internet Explorer which is set up to use a proxy, it pops up the log-in window to authenticate to the proxy server, in case it is not saved.

My problem is, if it is saved, I can take the default credentials and proxy server using

System.Net.WebProxy.GetDefaultProxy(); (I know this is deprecated, but it works for me. I would appreciate a more elegant solution).

and

System.Net.CredentialCache.DefaultCredentials

But, in case it is not saved, I want to pop-up the windows authentication window like the IE does. Is it possible to that? If yes, I would appreciate a little help, otherwise I have to write my own authentication window.

Please respond asap.

Thanks in advance.

Unable to call an asmx web service using windows authentication from a Service workflow

  
Hello, I need to use an existing asmx service from inside my service workflow and I am unable to call it. This asmx service is hosted in a web application with iis set to windows authentication, anonymous is not allowed. I need to send the authentication, only way seems too be using transport for basicHttpBindings. Every time I try to call the service I get an error saying that there is nothing listening to the url of the service generated automatically by VS when I added the Service Reference ? my web config <configuration> <configSections> </configSections> <system.web> <compilation debug="true" targetFramework="4.0" /> </system.web> <system.serviceModel> <protocolMapping> <add scheme="http" binding="wsHttpBinding" bindingConfiguration="WindowsCreds" /> </protocolMapping> <bindings> <basicHttpBinding> <binding name="UtilitiesSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"

Windows Service crashing on call to unmanaged code, even though console app version works

  

I have a C# program that at some point calls 2 functions from an unmanaged dll using p/invoke.  Everything works fine when I'm running in a console app.  When I compile the same program as a windows service and run it, it crashes.  The console app and service should be identical as far as my code is concerned... all either program does is create an object from another assembly of mine and run a Start() method on it.

I have used VS2010 to debug the managed and unmanaged code, and when I step through the Console app everything looks great.  When I attach the debugger to the service, i can step through the first function in the unmanaged code, control returns to the managed code, and then later when it comes to the point where it calls the second unmanaged function, the process terminates immediately before the debugger steps into the first line of unmanaged code.  There are no exceptions that I can see, and the only thing written to the event log is the generic "service terminated unexpectedly" message.  Running "sc query" on the command line lets me know the win32_exit_code is 1067.

Im running everything in .net 4, on winxp 32bit.  The serivce is running as Local System ideally, but the same behavior exists when I run it under my user account. 

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Web Matrix + Windows Authentication

  

I'm curious if its possible to get windows auth working with asp.net webpages/webmatrix.

I've got it published to IIS with windows auth turned on and anonymous/forms/basic turned off.

I'm guessing the WebSecurity Helper probably won't work here but can you access User.Identity.Name etc?

Sorry for the newbie questions, I've only just started working with asp.net ^^,

Using windows authentication to access SQL when using ASP.NET 4.0 via COM+

  

I am using SQL Server 2008 under windows authentication, front end is ASP.NET which uses COM+ to access database.

COM+ components are configured to run as domain user.

When looking through the logs (SQL Profiler), I can see the login name as the configured identity instead of windows indentity.

I have got Website running under "Intergrated Windows Authentication" and database is running locally on webserver.

Web configure contains entry for <identity impersonate="true"/>.

My connection string is

connectionString="data source=db01\test01;initial catalog=test; integrated security=SSPI;persist security info=False; Trusted_Connection=Yes"

Any ideas?

Regards

ASP.NET: Combine Web and Windows Services to Run Your ASP.NET Code at Scheduled Intervals

  

If you want to schedule ASP.NET tasks, one solution is to use a Web service to provide an interface to your ASP.NET application and build a Windows service that calls to it at scheduled intervals. Thus the ASP.NET application doesn't have to own the scheduling logic. Here the author shows how to schedule your ASP.NET tasks using a Windows service to initiate the Web service call because Windows services can start themselves when Windows boots up.

Threading: Break Free of Code Deadlocks in Critical Sections Under Windows

  

Critical sections, a mechanism that prohibits more than one thread at a time from executing a particular section of code, is a topic that has not received much attention and thus tends not to be well understood. A solid understanding of critical sections in Windows can really come in handy when you need to track down multithreading performance issues in your code. This articles delves under the hood of critical sections to reveal information useful in finding deadlocks and in pinpointing performance problems. It also includes a handy utility program that shows all of your critical sections and their current states.

Debug: Detect and Plug GDI Leaks in Your Code with Two Powerful Tools for Windows XP

  

In a previous article, the author devised a simple method to detect Graphical Device Interface (GDI) objects that are not properly released by Win32-based applications on Windows 9x platforms. Because some newer versions of Windows require a slightly different approach to GDI leaks, the author has updated his techniques for those operating systems. He builds and explains two tools designed to detect and eradicate GDI leaks in applications running on Windows XP, Windows 2000, and Windows NT.

Windows UI: Our WinMgr Sample Makes Custom Window Sizing Simple

  

Programmers using Visual Basic have always had an advantage over C++ programmers when it comes to component and window sizing. There are many third-party Visual Basic-based solutions to this age-old problem, but unfortunately, there are few elegant alternatives for the C++ crowd, short of using a full-fledged windowing toolkit. This article explains how to circumvent the tedious task of hardcoded pixel arithmetic. It starts by introducing a window sizing rules system, and then moves on to show how CWinMgr, a data-driven class, can intelligently manage an MFC application's window sizing.

Windows Script Host: New Code-Signing Features Protect Against Malicious Scripts

  

Downloading scripts from the Web or e-mail leaves users vulnerable to security risks because scripts can't be signed. But now developers can use Windows Script Host (WSH) to hash scripts so users can verify their source and safety. With WSH, scripts can be signed or verified using all the same tools ordinarily used to sign EXE, CAB, DLL, and OCX files. This article discusses public-key cryptosystems, the process of signing and verifying scripts in WSH, and several warnings about attacks that could potentially be made against cryptographically secured scripts and ways in which to avoid them.

Browser window is opening up on the second click with javascript code

  

Hi,

I am trying to set a javascript code to open up a new browser window with this URL that exists like shown below.

On the first click nothing happens but on the second click the browser window is opening up.

 

How is it possible to make it open up on the first click ?

                                <asp:ImageButton ID="ImageButton3" runat="server" Height="84px" 
                                    ImageUrl="~/images/1.jpg" Width="165px" 
                                    onclick="ImageButton3_Click" />

    protected void ImageButton3_Click(object sender, ImageClickEventArgs e)
    {
        String openURL = "javascript:window.open('" + "Folder1/testing.aspx" + "');return false;";
        ImageButton3.OnClientClick = openURL;
    }
