I'm using a webbrowser control in WPF to show a virtual earth map, but because I'm developing behind a proxy of my company, every time I try to see the map, I have to insert my credentials.
I would like to insert them automatically in the c# code, how can I achieve that?
I already try in the navigating event of the web browser using:
void webBrowser_Navigating(object sender, NavigatingCancelEventArgs e)
{
//NetworkCredential credential = new NetworkCredential("u007239", "****", "****");
//e.WebRequest.Proxy.Credentials = credential;
}
But this doesn't work because I'm getting that e.webrequest is a null object.
all the help is welcome.
Can you not just put the following in your app.config?
<configuration>
<system.net>
<defaultProxy useDefaultCredentials="true" enabled="true"></defaultProxy>
</system.net>
</configuration>

I am using wpf webview2 to build an app , the webview2 will navigate to my website which has one button to connect to audio , but i want to make it connect to audio automatically , so i tried use code like
document.getElementById("audioBtn").click(); to try to connect to audio.
But seems this doesn't work, i still have to manually click the button rather than trigger the click by script. (maybe due to some browser security policy ?)
I also tried to auto allow the permission in webview2
private void CoreWebView2_PermissionRequested(object sender, CoreWebView2PermissionRequestedEventArgs e) { e.State = CoreWebView2PermissionState.Allow; }
So how can i automatically connect to audio ? Both the WPF application and the web application is mine.. so there is no security risk..
thank you so much...

private void CoreWebView2_PermissionRequested(object sender, CoreWebView2PermissionRequestedEventArgs e) { e.State = CoreWebView2PermissionState.Allow; }
You might be trying that click before the content is properly loaded, in which case there will be no document there or element in it.
Assuming this is the problem then you can handle the navigation completed event.
https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2.navigationcompleted?view=webview2-dotnet-1.0.1245.22
Something like:
wv2.CoreWebView2.NavigationCompleted += (s, at) =>
{
wv2.ExecuteScriptAsync("document.getElementById('audioBtn').click();");
};
Before you navigate
I am using the ReportViewer in my WPF application and I am trying to get a custom protocol to work with the application. So I get the ability to open sub-programs inside my application when a url is clicked inside the ReportViewer.
When I click on the custom-protocol-url (inside the ReportViewer) nothing happens.
When I open the same report via the Web-Browser, my URL works flawlessly.
It seems like the ReportViewer doesn't allow custom protocols? Has anyone experienced that aswell? Is there any documentation on that?
http, https and mailto are working in the ReportViewer.
I am just adding an Action in the Report pointing to my url
customurl://123
Url definition:
[HKEY_CLASSES_ROOT\customurl]
#="URL: customurl Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\customurl\shell]
[HKEY_CLASSES_ROOT\customurl\shell\open]
[HKEY_CLASSES_ROOT\customurl\shell\open\command]
#="\"C:\\Extra Programme\\TestAlert.exe\" \"%1\""
Testalert (just the test-program by microsoft):
static string ProcessInput(string s)
{
// TODO Verify and validate the input
// string as appropriate for your application.
return s;
}
static void Main(string[] args)
{
Console.WriteLine("Alert.exe invoked with the following parameters.\r\n");
Console.WriteLine("Raw command-line: \n\t" + Environment.CommandLine);
Console.WriteLine("\n\nArguments:\n");
foreach (string s in args)
{
Console.WriteLine("\t" + ProcessInput(s));
}
Console.WriteLine("\nPress any key to continue...");
Console.ReadKey();
}
I have looked into the code of ReportViewer and found an if statement, that checks if the url starts with either http:// or https:// or mailto:.
It gets this information with Uri.UriSchemeHttp, Uri.UriSchemeHttps and Uri.UriSchemeMailto
So you could overwrite eg. Uri.UriSchemeHttp with "customurl" (if your url is customurl://123) before rendering the report.
var field = typeof(Uri).GetField("UriSchemeHttp");
field.SetValue(null, "customurl");
The more elegant solution would be, to use a webbrowser control and just show the SSRS Web-Page

I'm building a Silverlight app that will run on Azure. My VS solution has two projects: the web role and the Silverlight. The web role has a Service that works. (I can go to localhost:88/expenseservice.svc/expenses and get the data I want.)
I am trying to access that data from Silverlight:
private void MainPage_Loaded(object sender, RoutedEventArgs args)
{
WebClient data = new WebClient();
data.DownloadStringCompleted += new DownloadStringCompletedEventHandler(data_DownloadStringCompleted);
Uri dataSource = new Uri("localhost:88/expenseservice.svc/expenses");
data.DownloadStringAsync(dataSource);
}
void data_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
if (e.Error != null)
{
MessageBox.Show(e.Error.InnerException.Message);
return;
}
// ...
}
However, this does not work. The message box shows the error:
The URI prefix is not recognized.
Here is the full exception:
e.Error.InnerException = {System.NotSupportedException: The URI prefix is not recognized.
at System.Net.WebRequest.Create(Uri requestUri)
at System.Net.WebClient.GetWebRequest(Uri address)
at System.Net.WebClient.DownloadStringAsync(Uri address, Object userToken)}
Is it complaining about localhost? Am I supposed to be doing something differently? Perhaps this is what "Add Service Reference" is for?
I think the prefix is not recognized because it is missing. The prefix should be the first part that describes what kind of service your URI is pointing to. For example http:// of svn:// and so on..
Just add the right one and it should work.. (I've never used Silverlight neither anything Microsoftish so I'm just guessing)
I've created a Silverlight project that produces [something].xap file to package a few silverlight UserControls. I would like to manipulate that .xap file through the use of javascript in the browser to show and hide user controls based upon java script events.
Is it possible to do this?
If so any sample could or links to documentation would be appreciated.
Thanks in advance

Here's my solution...not sure if it's the "best-practices" way...comments????
In the App class within my Silverlight application I have the following code:
private Page _page = null;
private void Application_Startup(object sender, StartupEventArgs e)
{
_page = new Page();
this.RootVisual = _page;
HtmlPage.RegisterScriptableObject("App", this);
}
Also to the App class I add a [ScriptableMember] to be called from JavaScript
[ScriptableMember]
public void ShowTeamSearch(Guid ctxId, Guid teamId)
{
_page.ShowTeamSearcher(ctxId, teamId);
}
The Page class is the default one that get's created within the Silverlight Control project, it really doesn't have any UI or logic, it's just used to swap in/out the views.
Login oLogin;
TeamSearcher oSearcher;
public Page()
{
InitializeComponent();
oLogin = new Login();
oSearcher = new TeamSearcher();
oLogin.Visibility = Visibility;
this.LayoutRoot.Children.Add(oLogin);
}
Also a method is added to show/hide the views...this could/will probably get more advanced/robust with animations etc...but this shows the basic idea:
public void ShowTeamSearcher(Guid ctxId, Guid teamId)
{
oSearcher.UserTeamId = teamId;
oSearcher.UserContextId = ctxId;
LayoutRoot.Children.Remove(oLogin);
LayoutRoot.Children.Add(oSearcher);
}
Then to invoke this in the JavaScript after assigning the id of oXaml to the instance of the silverlight host.
var slControl = document.getElementById('oXaml');
slControl.Content.App.ShowTeamSearch(sessionId, teamId);
This seems to work and isn't all that bad of a solution, but there might be something better...thoughts?

I'm trying to use the WebClient class to download a html file from another website and present it as a text stream, But I'm getting a security error, what am I doing wrong, or is this another one of Silverlights security "Features"
[code]
namespace ImageScrape
{
public partial class Page : UserControl
{
public Page()
{
InitializeComponent();
}
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
WebClient cl = new WebClient();
cl.OpenReadCompleted += new OpenReadCompletedEventHandler(cl_OpenReadCompleted);
cl.OpenReadAsync(new Uri(#"http://www.google.co.uk/",UriKind.Absolute));
}
void cl_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
{
testTextBlock.Text = e.Result.ToString();
}
}
}
[/code]
EDIT
Thanks guys, I was really hoping I wouldn't have to create this as a WCF service as 1) I only know the basics and 2) The idea is that you can use this .xap without having to connect to a central server, mainly because for this I don't have a server that I could host a WCF service on.
Does anyone know a way to get around this, or anywhere that would host a WCF service for free?
I think there are security issues with going directly to another site from the silverlight client.
The best work around for this would be to move this code into a web service and then serve the content you require to client from there.
