I have two fully trusted out of browser applications.
What i want is to be in one and a user clicks a button and that opens the second silverlight oob application.
Is this possible?
pinvoke and sllauncher contain the answer that you seek.

Can I automate actions like filling and submitting a form, clicking links et.c. in a real browser (i.e. IE11 or Firefox) using only a Silverlight or an XBAP application?
I would be grateful if you could let me know any other solution (other than the two above) that can do the automations without the need to manually install third party software (like Selenium or Telerik Testing Framework).
No one answered, so I'll tell you what worked and what not.
Silverlight solutions didn't work due to the Same-origin browser policy.
The XBAP solution actually worked. I created a new XBAP application and loaded it in my other application inside an iframe.
The user must accept the pop-up and the XBAP application opens a new WebBrowser control doing its stuff.
The whole thing only supports IE.
I am developing a windows phone application.
In a page I placed a button and on this button click I open the webbrowser and redirects to our website pages for some processes. There are many webpages. In the last webpage we added a button "Close". In the close button click I want to close the webbrowser and open the application back with the last state before opening the webbrowser. How can I do this ?
Thanks.
I will refer to the button in the app as "app button" and the button in the web page as "close button".
Add a WebBrowser control called webBrowser1 to the Windows Phone app. Make it cover the entire screen, and set it's Visibility property to Collapsed.
On the app button's click event, use
webBrowser1.Visibility = System.Windows.Visibility.Visible;
webBrowser1.Navigate(new Uri("http://yourwebsite.com/page");
to show the web browser and navigate it to the first page on your website.
Make the close button on the last page of your site navigate to a new page on your site, called "close.html" or whatever you want. In javascript, this would look like
<Button onclick="window.location.href='http://yourwebsite.com/close.html';">
Back in the app: On webBrowser1's Navigating event use,
if (e.Uri.ToString().Contains("close.html"))
{
webBrowser1.Visibility = System.Windows.Visibility.Collapsed;
}
When the you click the button on the last page of your site, it navigates to "close.html". When this happens, the Web Browser's Navigating event fires. Since this event fires every time you change pages, you need to check to see if the new url contains "close.html", the page your close button is navigating to. If it does, the Web Browser will be hidden and you will see your app again.
.
(In VB, the code would be )
webBrowser1.Visibility = System.Windows.Visibility.Visible
webBrowser1.Navigate(New Uri("http://yourwebsite.com/page")
And
If e.Uri.ToString.Contains("close.html")
webBrowser1.Visibility = System.Windows.Visibility.Collapsed
End If
Edit: I was thinking in generic terms when i wrote the answer and did not remember that you are asking specifically about the webbrowser (hence, using a webbrowsertask launcher). Thank you #Claus for point out the OAuth situation. So, i am amending my answer to explain that it is possible and also mention an issue with using the launcher as there is no way guarantee to return back to a given point in your launcher app (as it is with choosers due to the availability of callbacks).
It is not possible to achieve this in general terms. That is, there is an application A which opens another application B and from application B you would like to close-it-and-open-A. There are many reasons why i think it is not possible:
- How does one get the address/reference to the application A. No API for that at the moment.
- There is no content-handler/plugin where a 3rd party can register an app with the web-browser.
- Most importantly, security, security, security. This would open doors for attacks from the web.
However, for your requirement of application B being a web-browser, it is possible to use a task launcher WebBrowserTask. As #claus suggests, you could have Window.close() javascript in your last page to close the browser and hence reveal the app underneath it (hopefully, A). The problem here is that if, the user opens an app (let's call it C) after the browser has launched (and before the browser is closed), and the user does not close C, then when the browser gets closed, the user will be returned to C and not to the launcher App! This is not what you want based on your requirement.
So, if you would like to achieve the kind of effect you are describing in your question, it is best that you embed the Web-browser in your application (as a full-screen app) and from that vantage point you can interact between the web-browser (control) and the (host) app via Javascript.
Hopefully, this helps.
As we all know very well..
whenever we create application inside silverlight it is asking us for hosting it
by dialogue box at given below.
My question is what if i unchecked the check box[Host the silverlight application in a new web site].
Means what kind of problem we have to face later if I don't host our Silverlight Application in any of the option given by dialogue box.
Basically it is not a problem at all. You can add a website at any time later.
In the project settings of a website there is a Silverlight tab. Under that you will find the option to add Silverlight projects to the website. This will setup the links to generate the XAP in ClientBin as well as giving you the option to create test pages for each Silverlight app added. The test pages will give you the sample JS you need to host your Xap later.
You will have to eventually host your application somewhere otherwise it will stay on your local harddrive and hardly reach any clients. So if you have an existing web site you could simply copy-paste the necessary javascript to this site later in order to embed your Silverlight application. In this case you can uncheck this checkbox.
Our application uses a webbrowser control on a form to navigate to our website when a certain action is performed on our 'text-based' legacy application.
All was fine in IE5, 6 and 7 but now it appears IE8 shares session cookies not only between tabs in the same intance but also between all instances. This is a major bother if a user wants to have two separate instances looking at different client details at the same time.
One can disable the latter behaviour by starting IE with the command line switch -nomerge.
Does anybody know how we can achieve the same effect programatically with the WebBrowser control?
Thanks in advance chaps.
If the same Silverlight application is running in two web browser tabs, does each tab use a separate application domain?
If you know where Microsoft explicitly provides this information, please include a reference.
Not direct from Microsoft, but one AppDomain per Silverlight instance:

To clarify Corbin's answer:
Its one AppDomain per instance of the Silverlight control, so that two Silverlight apps on the same page are segmented into AppDomains. Depending on the browser, there may be separations between tabs (e.g. IE8 and Chrome uses separate processes, whereas Firefox and IE7 do not). The only way to get two Silverlight instances to talk with each other is on the same page and to communicate through the HTML Bridge.
The browser is completely in control of the tabs, and should keep them separate for obvious security reasons.
