My problem
I am currently developing an electron (v4.2.10, I can't upgrade) application with the primary purpose of browsing on a specific homepage (using electron-navigation) and making their flash games playable.
I have included the Pepper Flashplayer (v32.0.0.156) for this purpose and so far it is all working well.
However when trying to print a page including a flash game it will print a blank page. Trying the same in my current versions of Chrome or Firefox (with current flash player) yields the same result, however in Edge it works.
What I've tried so far
I have no access to the actual pages of the site or any of the swf files
The pages with the swf files are http (I tried setting browserWindow web preference disableWebSecurity to true, no change)
I have tried different versions of the flashplayer
Screenshotting the page is sadly not an option
I have looked into the plugin nw-flash-trust but I am accessing an external source
When I downgraded electron to v3.0 it actually managed to print most of the display, which may point to it being related to the underlying chromium version
Does anyone have an idea how I can fix this? I have absolutely no knowledge of flash development itself. I would love to be able to print on v4.10 too. Many thanks for any help!

I'm developping a web server based on SpringFramework 4 and I hope to return some files and open them directly in the browser.
So far, I succeed to treat PDF by using Header Content-disposition: inline. But it is not working for word/excel. Google Chrome proposes to download the later or download/open by application.
So I hope to know
whether or not it's possible to open them directly in the browser
if yes, how to do that
As far as i know there is no built in Excel viewer for most browsers (IE is different because it is part of Windows, and so is Office). PDF is a different story ... there are loads of plug-ins available.
You might want to consider opening it in google docs, or office.com.
Apparently, there is a plugin available for firefox ... http://www.microsoft.com/en-gb/download/details.aspx?id=27106
BUT that does mean any users will have to have it installed for them to get the behaviour you want!
I have been doing a lot of reading and studying to figure out.
I basically just want my main AngularJS application to run, but also include an embedded Chrome Extension app - in this case, have regularly scheduled alarms (using the chrome.alarm API).
I want all users of my AngularJS app to have automatic access to the Chrome extension app, embedded in the main clientside one with lots of other Angular features.
It seems like I have to manually enable my Chrome app in Developer mode on my browser and even drag my Chrome app specifically to a location in my Chrome browser. I don't understand how end users can just automatically use my Chrome app then.
I need to add here I have never really used jQuery, only AngularJS but AngularJS extensively. My AngularJS app is the frontend, the backend is provided by Rails.
Some advice would be really helpful. I hope I am not downvoted as it is strange how sometimes questions get downvoted and I am not sure why...I don't really know where else to go with this question.
EDIT:
Ok some code to demonstrate:
myangularapp.controller('myappcontroller', function($scope, $http) {
var delayvar = 5;
chrome.alarms.create("arandomalarm", {delay: delayvar});
};
This doesn't just work as part of my AngularJS, I tried creating a manifest.json file in the app/assets folder too. As well as a background.js file there and my-chrome-app.js file. "chrome.alarms" is undefined, but I haven't enabled Developer mode yet. But still, how are end users supposed to use it if just to make me use it I need to do so much specific browser configuration?
You should have a look at Content Scripts and then at Message Passing which explains you how to communicate between a web page and an Chrome extension.
its not possible to automatically install a chrome extension. the user must install it from the chrome store.
you may make it easier for them to install it by providing an inline installation from your webpage. its in the official documentation and you can see an example on this page with the "add to chrome" button:
http://plusfortrello.com (one of my chrome extensions which has inline installation inside that page).
that example button is further customized to display a message instead if the user is not on chrome desktop.
if your extension also has permission to your webpage then you can also detect from your webpage if the extension is already install it (to hide the button, send messages to it and such).
I am creating an application that runs in chromium portable in full screen with the --kiosk flag. It is written in HTML, JavaScript, and CSS. I am also using the HTML5 File System to store some large sets of data. The application opens up in full screen, and the info bar to request permanent storage pops up.
The problem is that, while running in kiosk mode, you cannot select either "OK" or "Cancel" to the file system's request to store data. You can only close the info bar with the "X". This results in the file system not getting any kind of quota and the application fails.
So is there a way to have unlimited storage for an application running from "file:///"? I have tried using --unlimited-storage but it doesn't seem to work for a webpage.
Is there a way to open up in full screen without using --kiosk? Any other work arounds or suggestions are welcome.
What version of Chromium Portable are you using? I had a similar issue awhile back, but I don't have the same problem in the newer versions. I am using the latest version as of now which is Chromium Portable 30.0.1599.10 (released on 2013-08-21).
I am currently making a web app and I have used a manifest file to get my web app to work offline. This works great and using Google Chrome, Opera etc I can view what is being cached by right clicking, inspecting the element and viewing the resources.
The problem I have is that I want to view what is stored in the cache in the app when it is being used on an i-pad. I have give this a Google but cant seem to find anything. Is there a way of displaying what is stored in the cache using some JavaScript or JQuery and then having this displayed on a web page within the app.
The app consists of a webview which is currently pulling in other html pages which are being stored in the cache using the manifest. I want to add a simple settings page where what is being stored in the cache can be viewed within the app. Hope that explains enough I would really appreciate any help with this matter.
I don't know of a way to get at this information with JavaScript either, but here are the alternatives I use.
In Mobile Safari, I connect the device to a Mac, open Safari on the Mac, open the site in Mobile Safari or open the native app going to the screen with the UIWebView, go back to the Mac and open the Develop menu. From there you can select the Storage option and view what's in the appcache.
In Chrome, you can view what's stored in the appcache using the URL chrome://appcache-internals/.
If the appcache was saved successfully, you could also simply go to the file itself in your browser.
I have linked to the Jquery library at google in my header, and my local copy of the Galleria Javascript file - as the instructions on the Galleria website said to do.
The code functions perfectly in Chrome. However, when attempting to view the site in IE9 I am faced with "Internet Explorer restricted this webpage from running scripts or ActiveX controls." This is preventing (without user input) the Javascript/Jquery/Galleria stuff to function; it is also prevented an embedded Youtube video from displaying.
What am I missing - plenty of other websites use these functions and I don't get IE giving this message. What do I need to add or change?
I am viewing the website from my PC - it is stored locally at the moment.
Cheers!
This is happening because you are running your website locally. You can be sure that this will not happen once you upload it to a webserver.
You can also run a local webserver. I can recommend WAMP:
