I am looking for a way to implement Internet explorer - a desktop version in my Winodws 8 app . This is caused by my c# application- i need to run javascript page but its impossible in metro version of IE. Is there any method to do this?
I `ll describe my problem: when i want to load html of DOM page(rendered by javascript) i cant because javascript can run (I use WebView). I tried to open this page using Desktop version and it worked perfectly. Unfortunately Metro IE10 cant show the content and my WebView too.
Thanks for help.
You can sure inject in the c# webview a javascript file:
This is the action for a button:
private async void Lamp_Click(object sender, RoutedEventArgs e)
{
Uri uri = new Uri("ms-appx:///js/injected.js");
StorageFile file = await StorageFile.GetFileFromApplicationUriAsync(uri);
string text = await FileIO.ReadTextAsync(file); //reading content as string
var script = "(function(){" + text + "})()";
}
try
{
var result = wv.InvokeScript("eval", new string[] { script });
}
catch (Exception) { }
wv is you id name for the webview element in the xaml

I have an wpf app that I want to use to open another wpf app.
Call them image viewer (Gallery) and image storage (AppToAppCommunication).
Image storage app shows a list of available images.
Then, on ListBox selection changed I have this code:
private async void lbImages_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var options = new LauncherOptions();
options.ContentType = "image/jpg";
var filePath = Environment.CurrentDirectory + "\\Images\\" +
((ListBoxItem)((ListBox)sender).SelectedItem).Content;
var file = await StorageFile.GetFileFromPathAsync(filePath);
var token = SharedStorageAccessManager.AddFile(file);
ValueSet inputData = new ValueSet();
inputData.Add("Token", token);
Uri uri = new Uri("myprotocol:");
//await Launcher.LaunchUriAsync(uri); // #works
//await Launcher.LaunchUriAsync(uri, options, inputData); // #doesn't
}
Now, when I use the line at #works, it works, with no image shown, as expected.
But, when instead I use line at #desn't, it gives me this error:
Now I tried clicking OK on the popup and running a new VS instance an waiting for it to load, but it never does.
I've tried running both applications from the same solution and I can get to a breakpoint in override void OnActivated in image viewer app (Gallery) when using the #works line in image storage app (AppToAppCommunication), but I can't get to that same breakpoint when using the #doesn't line.
I don't know what the problem is and I am not able to debug it.
How could I go about finding a way to debug this properly?
So I'm creating a program that can go into google and search for the word that has
been saved into a variable. So my question is how I can do this, without having it go to a URL instead just going to Google and search "whatever" Here's the code.
private void button2_Click(object sender, EventArgs e)
{
if (Script.Text == Script.Text)
{
Console.AppendText("\n[1] Loading Websites of " + Script.Text + "...");
}
WebClient wc = new WebClient();
Process.Start(#"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", "Scripts " + Script.Text);
}
This should solve your problem
public static void GoToSite(string url)
{
System.Diagnostics.Process.Start("chrome.exe", url);
}
you can also change browser dynamically by adding a second params
You can also do this:
String stringToSearch = “stackoverflow”;
System.Diagnostics.Process.Start(#"C:\Program Files\Internet Explorer\iexplore.exe", "http://www.google.com.au/search?q=" + stringToSearch);
This assumes IE is the default browser on your machine. If Chrome or Firefox is the default browser, then code will fail.
This is a useful link:

Maybe you can put it in a try catch block and see if there is an exception. If there is an exception with starting IE, then open chrome.
I'm trying to use the Twitter Service from the UWPCommunityToolkit, which I have running as a standalone UWP (Universal Windows Platform) app, but when I import it into Unity (2017.2.0f3) as a library, it doesn't open the authentication window.
This is what shows up on the working standalone UWP app:
When in unity, it seems to go through the setup code, but not run this line properly:
var result = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, startUri, endUri);
https://github.com/Microsoft/UWPCommunityToolkit/blob/master/Microsoft.Toolkit.Uwp.Services/Services/Twitter/TwitterDataProvider.cs#L293
It just returns WebAuthenticationStatus.UserCancel, whereas on the standalone UWP, it'd return WebAuthenticationStatus.Success. Note, it also returns WebAuthenticationStatus.UserCancel on the standalone UWP app when the user clicks the close button on the pop up.
Is it possible to run WebAuthenticationBroker.AuthenticateAsync (https://learn.microsoft.com/en-us/windows/uwp/security/web-authentication-broker) in Unity? Are there any other ways to do web authentication on the Windows platform using Unity?
I've also tried TwitterKit, but unfortunately, it doesn't have support for Windows UWP (only iOS and Android).
Thanks!
LINQ to Twitter supports UWP. It has a UniversalAuthorizer that works like this:
private async void TweetButton_Click(object sender, RoutedEventArgs e)
{
var authorizer = new UniversalAuthorizer
{
CredentialStore = new InMemoryCredentialStore
{
ConsumerKey = "",
ConsumerSecret = ""
}
};
await authorizer.AuthorizeAsync();
var ctx = new TwitterContext(authorizer);
string userInput = tweetText.Text;
Status tweet = await ctx.TweetAsync(userInput);
ResponseTextBlock.Text = tweet.Text;
await new MessageDialog("You Tweeted: " + tweet.Text, "Success!").ShowAsync();
}

I'm creating a simple news feed, it i want it can open the browser to show the details of the news, but i don't know how to close the browser , here is the code of how I open the browser,anyone can teach me how to off the browser using uwp? '
public async void test()
{
RootObject mynews = await NewsProxy.GetNews();
string website = mynews.articles[i].url;
var uriWeb = new Uri(websites);
var success = await Windows.System.Launcher.LaunchUriAsync(uriWeb);
if (success)
{
//Uri launched
}
else
{
// uri launch failed
}
}
var success = await Windows.System.Launcher.LaunchUriAsync(uriWeb);
Your code is actually telling the OS to Launch the given url and the OS in turn launches the default browser with the given URL. So you are not actually launching the browser.
In order to have full control over the browser behavior you can implement your own WebView and then use the url to navigate your WebView.
webView1.Navigate("http://www.contoso.com");
(MSDN Documentation for WebView)
I want to be able to open a PDF using the native Windows Reader Application when a user clicks on a button. So far I am able to use the following code to successfully open files that end with the (.PNG) extension. However, when I let the link to open the (.PDF) file I get the following error.
The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
The file destination is correct.
Here is my code:
private async void btnLoad_Click(object sender, RoutedEventArgs e)
{
// Path to the file in the app package to launch
string imageFile = #"Data\Healthcare-Flyer.pdf";
var file = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync(imageFile);
if (file != null)
{
// Set the option to show the picker
var options = new Windows.System.LauncherOptions();
options.DisplayApplicationPicker = true;
// Launch the retrieved file
bool success = await Windows.System.Launcher.LaunchFileAsync(file, options);
if (success)
{
// File launched
}
else
{
// File launch failed
}
}
else
{
// Could not find file
}
}
}
