In it's very basic form I have a WebClient request for some xml in a Page.xaml code behind. Something like:
public Page()
{
InitializeComponent();
Uri uri = new Uri("Dummy.xml", UriKind.Relative);
WebClient webClient = new WebClient();
webClient.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient_DownloadStringCompleted);
webClient.DownloadStringAsync(uri);
}
void webClient_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error == null)
{
//Do something
}
}
If I setup my Silverlight project to run through an asp.net hosted page, and then put Dummy.xml in the ClientBin folder (relative to the xap) it works fine.
If I setup the project using just the automatically generated test page option, and again put the xml relative to the xap, the request doesn't work (although the completed event does fire).
My question is why? Is it a requirement that any Silverlight project that dynamically downloads has to be on a server?
Cheers

First up, try to avoid using the auto generated test page. It requires you to understand how the silverlight security by default model works when the xap is being accessed as a file.
To answer your question, you're encountering the security designed to prevent unauthorised cross-domain access.
Yes, there is no webserver for it to connect to! The autogenerated test page just opens that XAP directly without invoking Visual Studio's web server. If you want to do this you must use the other option to create a website with the silverlight project. Alternatively, you can embed the XML file in the XAP as a resource and access it as a resource.

I know that removing URL extensions is the new model for website programming. Unfortunately, my site is hosted on a hybrid server configuration. The call to my site goes into an Apache server that recognizes that my call is for a .aspx page, and passes the call along to an IIS server to complete the call. This complicates my website at this point because I am coding in Visual Studio 2015, and it models after the new rules of removing the extensions, and the call is never passed along to the IIS server.
I am not a big HTML guy, and I cannot find anything to place in web.config or my global.asax file for code to tell the system to overwrite the rule of removing the extension, and to keep my extensions. I have seen several posts here to remove the extensions, but nothing to keep them.
Basically, when I call www.mysite.com/Default.aspx, the current config removes the .aspx extension, and the call is for www.mysite.com/Default. I want to KEEP the .aspx extension on the call to the site so that it passes through the Apache server and to the IIS server. Any help would be greatly appreciated.
Have a look in your App_Start directory for a class called RouteConfig.cs and disable AutoRedirectMode using this line of code
settings.AutoRedirectMode = RedirectMode.Off;
This is what automatically removes extensions from your web pages.
Full example below...
public static class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
var settings = new FriendlyUrlSettings();
settings.AutoRedirectMode = RedirectMode.Off;
routes.EnableFriendlyUrls(settings);
}
}
I am working on Web Form project to deploy on production. In this project, dynamic folder is created on fly and put the new css style as per data configuration from database. This was handled by Handlers in web form. Application works locally without any error. But when I publish on production it does not find the dynamic created css file path. Its not physical exists it creates on fly. So it fails to download css and it missing all images and styles. Another team had developed this application and we are moving this from FireHost to Azure site. It was working on Firehost but no any luck on Azure site yet. I tried to remove manifest file in production by adding remove attributes .manifest in web.config. But no any luck yet. I appreciate your help Thanks
I am getting 404 errors,
Failed to load resource: the server responded with a status of 404 (Not Found)
I have the style css inject this way in site.master page.
<link href="/Styles/Dynamic/CompanySite.css" rel="stylesheet" type="text/css" />
It did not mentioned handlers in web.config. There is separate handlers folders and pages. In pages code behind file look like this in page load method.
StringBuilder sb = new StringBuilder(File.ReadAllText(Server.MapPath("~/Styles/CompanyStyles.css")));
string sPrimaryColor = "#B1D74C";

var BannerId = new CompanyThemeDataLogic().GetBannerId();
if (BannerId.HasValue)

}
sb.Replace("#PRIMARY#", sPrimaryColor);

Response.Write(sb.ToString());
Its not physical exists it creates on fly. So it fails to download css
and it missing all images and styles.
Where have you stored the files after the folder being created? Do you store them in website Azure vm disk? Please note
the VM disk storage is not persistent
if you have >= 2 instances on Azure to host the web app, and then you just created the css/images files on 1 instance (VM), later your end user may hit the other instance that has no such files.
so please store your files in Azure storage - blob and use its url in your project to connect to css/image files
I'm developing a website in VB.Net, visual studio 2010, that requires accessing a webservice to access the user's login information.
They are logged in through a separate page and when they redirect to my page I access their credentials through the webservice and then handle the session through my own scripts.
What I need to know is:
Can a webservice be checked on pageload if a condition isn't met?
I have not worked with webservices before and have no clue how to add parameters or how to get a value from it. Is it possible to add the reference to my login class(or a class in general)?
I have added a reference through the visual studio: website -> add web reference
But this simply generated a bunch of files and I can't find a good tutorial online about how to use the generated references/files.
I thought it was supposed to generate some class files, however it added a folder (.discomap) with the following types:
.disco
.wsdl
.xsd
Finally, can I test this webservice (which is online and running) on my local host?
Thanks!
It sounds like you're wanting to call these services from your code behind.
When you added a web reference it should have generated a bunch of class files you can use to call the service methods. You should be able to do this from localhost.
A WCF service call from the code behind would look something like this
ServiceReference1.Service1Client client = new
ServiceReference1.Service1Client();
string returnString;
returnString = client.GetData(Param);
label1.Text = returnString;
We have an application that has been developed by the third party, and I don't want to go back to them to get them to add in cache control for specific pages.
All the pages that need caching disabled are in a single directory.
The issue is that IE seems to not follow Cache-control:nocache properly, so we need to add in Pragma:nocache and cache age as well.
Is there a way to do this using configs in the directory? will it cascade through all child directories? Can it be done via the main web.config?
To be clear, I'm not looking for a way to do this via code, it needs to be via configuration of either IIS or the web.config files.
We're using ASP.NET 2.0 and 4.0, on IIS 6.0.
This can be done in IIS using the UI, it's actually quite easy, or atleast it was in my use case.
All you do is simply open up IIS manager, navigate to the site and then the directory you want to add the headers to Right Click -> properties.
Click the "Headers" tab, and add in the headers you require.
This goes recursively down the child directories, and adds the headers before any added by the code.
In IIS 7.0/7.5, you can use the StaticContent section of a web.config in each of the directories.
You can do that on global.asax
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpApplication app = (HttpApplication)sender;
string cTheFile = HttpContext.Current.Request.Path;
if (cTheFile.Contains("/ExtraDir/"))
{
// add your header here
app.Response.AppendHeader("Pragma", "no-cache");
}
//... rest code of...
}
I searched high an low and still cannot find a definite answer.
How do I configure IIS 7.0 or a Web Application in IIS so that ASP.NET Runtime will handle all requests -- including ones to static files like *.js, *.gif, etc?
What I'm trying to do is as follows.
We have kind of SaaSy site, which we can "brand" for every customer. "Branding" means developing a custom master page and using a bunch of *.css and other images.
Quite naturally, I'm using VirtualPathProvider, which operates like this:
public override System.Web.Hosting.VirtualFile GetFile(string virtualPath)
{
if(PhysicalFileExists(virtualPath))
{
var virtualFile = base.GetFile(virtualPath);
return virtualFile;
}
if(VirtualFileExists(virtualPath))
{
var brandedVirtualPath = GetBrandedVirtualPath(virtualPath);
var absolutePath = HttpContext.Current.Server.MapPath(brandedVirtualPath);
Trace.WriteLine(string.Format("Serving '{0}' from '{1}'",
brandedVirtualPath, absolutePath), "BrandingAwareVirtualPathProvider");
var virtualFile = new VirtualFile(brandedVirtualPath, absolutePath);
return virtualFile;
}
return null;
}
The basic idea is as follows: we have a branding folder inside our webapp, which in turn contains folders for each "brand", with "brand" being equal to host name. That is, requests to http://foo.example.com/ should use static files from branding/foo_example_com, whereas http://bar.example.com/ should use content from branding/bar_example_com.
Now what I want IIS to do is to forward all requests to static files to StaticFileHandler, which would then use this whole "infrastructure" and serve correct files. However, try as I might, I cannot configure IIS to do this.
II7 already does that if the application pool's Managed Pipeline Mode is set to Integrated which is the default. In Integrated mode, ASP.NET handles all requests including those for static objects.
If you have to leave your application pool in Classic Mode then you need to use the same techniques you would use in IIS 6 to explicitly create handlers for the various static extensions.
Additional Information Based on Comments: I think your missing piece is creating an HttpHandler to handle the other extensions (.js, .css, etc.). Without this, then ASP.NET will use the default handling for these types of files. You would create a reference to you handler in your web.config. This article is an example of creating an HttpHandler for static files.
Kudos to everyone, but the problem was in totally different space.
VirtualPathProvider cannot be used in a pre-compiled web site. I'm furious.
