I recently updated from CefSharp 1.25.7 to the most recent (39.0.0-pre02) in the hopes that it would be easier to detect when a link is clicked. In 1.25.7 there was a navigation type but that was very unreliable and even directly clicking links would just count as "other" instead of "link clicked".
Basically my use case is that I have a hosted "start page" in my application that has many links. I would like to let the user open those links in their external browser, which isn't hard other than the fact that I don't know what is a link click and what is the page just navigating around. Most of our users (myself included) will have firewalls so when they open the first time it will redirect a bunch. Unfortunately some of those redirections and navigations have transition type of "LinkClicked" for some reason so I can't just check that in the IRequest in OnBeforeBrowse. Any ideas how I could tell that a link was actually clicked so I know to direct it to the system to open in their default browser?

I am developing a PWA using react JS
There is a requirement that we need to display the add to Home screen even after the App has been added to the Home screen for the first time
Can any body suggest if this is possible and how?
INFO: Mostly this app will be run on Google Chrome and Safari
Refer to this answer. You simply can't do that, unless you want to do it in specific development/test machines where you can set the below chrome flag,
chrome://flags/#bypass-app-banner-engagement-checks
You can't expect all your end users to set this flag, so this can't be a solution for all the real users.
I also don't see why you would have to show the banner even after adding to home screen, for any other use case. Browsers don't allow this for obvious reasons. It will be annoying the user, if the prompting is left to developers. Linked answer have more clarification on the same.
I'm just trying out a simple app in the CocoonJS launcher which contains some links that open some external page.
This works fine, but the problem is that I can't identify a way to go back a page (i.e. history back). The launcher app just displays the page in fullscreen, no user controls visible at all. This is troublesome, because when my users tap on an ad, I want them to be able to go back to the game.
Am I missing something or is this simply not supported?
I do not know of any way to display a navigation bar or something similar.
Nevertheless, you can open your external urls via Cocoon.App.openURL(url); which will enable the user to open it via a normal browser where you can navigate back.
Regards.
I agree with the solution proposed by Scdev. Also, interstitials or fullscreen ads usually have a dismiss button themselves. I might be misunderstanding something.

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.
I have a tab with an iframe external web page that loads... I would love a hyperlink inside that web page to link one of my photo albums in "theater" mode so you don't leave the page. However, any link I program inside that web page just brings in that photo album inside (not popped up and not in theater mode no matter if I have the &theater in the url).
Can I get some help on how to do this? Thanks!
this is a limitation of iframes in general. Less of a limitation and more of a security issue. As you said.. the iframe loads and external page - a page that could essentially come from anywhere. To protect the integrity of the site displaying this external page, the iframe can not access the page that contains it.
You might want to try opening a new window using javascript :
window.open ("{path_to_image}","title","menubar=1,resizable=1,width=350,height=250");
as you can see there are several options that you can set to customize the popup window.
Here is another link with some info about iframes
i have just had an app denied in the windows phone market place because i didn't adhere to the "close application on back button" rule.
currently i am doing the following:
open app
if you've never entered your details, navigate to the save details page
on arriving at this "first entry" page i cancel the use of the back button
because as you can see the first view that the user sees is my "first entry" page although i'm trying to be smart and lock the user from going back to an empty main page (because they havent entered their details) i'm really stopping them from exiting on the first screen.
as there is no way to exit using code in silverlight as per
http://blogs.msdn.com/b/ptorr/archive/2010/08/01/exiting-a-windows-phone-application.aspx
what am i supposed to do?
should i let the user navigate back and then try and capture that they have just hit back and navigate back again? (this seems like and odd way of doing it)
or is there a way for me to capture the first navigation instance and simply not store the first page actually loading into the history, so that when they hit back, it exits anyway?
I'm going to assume you mean "close app on back button rule"
I think the approach that will work for you and stick within cert reqs is to redirect the intial navigation... this will cause your initial page to not enter the backstack. Peter offers two implementations for this here.
