I have a small 2D game engine written in C#, using DirectX. Is it possible to somehow run it in a browser as a plugin? Like for example Flash and others, where you go to a site with a game and it will ask you to install a certain plugin and then you can play the game in the browser, with mouse and keyboard input.
I have searched around for hours and I still don't know what I'm looking for. I have so far primarily focused on Internet Explorer, but there are plugins, addons, extensions, etc I don't know what I need really.
Yes I think it is possible.
For example, I have an HTML page which includes an element like this:
<object id="simpleControl1"
classid="http:RenderTextProject5.dll#RenderTextProject.ScrollableControl"
height="300"
width="300">
</object>
The 'classid' attribute value has the following meaning/syntax:
RenderTextProject5.dll is the filename of a compiled .NET assembly
RenderTextProject.ScrollableControl is the qualified name (namespace plus classname) of a class which subclasses System.Windows.Forms.Control
I can then see the control being rendered in the browser.
I'm using IE (IE8, but it used to work with IE6 too), and I have the .NET framework installed on my machine (but I think I needn't have the RenderTextProject5 assembly installed on the client machine).
There may be some other caveats too (e.g. I needed to run in the Intranet security zone).
See Return of the Rich Client: Code Access Security and Distribution Features in .NET Enhance Client-Side Apps.
Look for Silverlight.. It is maybe not exactly what you need but it is a browser plugin capable of running C# code ;)
There is a relatively new plugin called Unity. It is a bit more complex, as it is a dev/3D authoring environment on its own, but uses C# as its language as far as I know. However I don't know if pure 2D programming is possible (well, may be worked around using ortho 3d?).
The basic version is free to download recently, maybe worth a check.
It is possible to run C# applications in a web browser without using plugins. For example, C# applications can be compiled into JavaScript applications using JSIL.

I need to build a web based application that can list available ssid in the area.
From my understanding, these probably can do what i want
Java applet
Adobe Flash
However, Im not sure whether these can do or not
HTML5/JavaScript
Java Web Start
I'm a .NET developer and I'm not familiar with these web technologies.
Are there any other method to get a list of SSID that i have not mentioned?
Thanks.
You'll never be able to list available SSID's with HTML5, Javascript, or any other strictly web-based technology. That's a very low-level task and won't be natively possible in any browser for security reasons. That being said, you may be able to draw on some technology like Java Applets, ActiveX, or even Silverlight 5 if I remember correctly. I don't know your project requirements, but you're better off creating a native application for this type of feature. If this application is being used by/sold to the general public, you're setting yourself up for a lot of headache by going with Applets/ActiveX/etc.
I'm a Microsoft stack developer most familiar with Windows Forms and WPF, but have a need to develop a Linux desktop application that can display some web apps in a modern browser that offers very recent HTML 5, CSS 3, SVG, etc.
I'm thinking GtkSharp running on top of Mono is probably the replacement for WinForms/WPF running on top of .NET which will best leverage what I already know. As for the embedded browser control, I have other requirements strongly advocating CEF over any other solution (although I'm still open to strong suggestions to do otherwise).
Anyone have experience with any of this?
Try looking at CefGlue, it has a CefGlue.Demo.GtkSharp project which would indicate it's possible.
https://bitbucket.org/xilium/xilium.cefglue/
https://bitbucket.org/xilium/xilium.cefglue/issues/108/linux-support
Personally I've never used CefGlue so I cannot say more than I've seen in passing.
I have used several solutions like Berkelium project, CEfSharp, awesomium.net, The Web application i built constitutes of Javascipts, xml, CSS. When I used these solutions for files published on server they properly work out but when i give path like (file:///path) it stops responding.
Depending on your needs as alternatives to file:// maybe look at either:
Implementing a SchemeHandler as showcased by both the CefSharp.WinForms.Example and WPF ditto.
Maybe even an OWIN married with CEF implementation, like Harley
or see this other answer: Ajax not working in CefSharp based WebView with local files
I've found this nice article about the "injected Way", but the author never finished it :
http://hightechstartups.blogspot.ch/2012/05/different-way-of-developing-browser.html
I would like a bare bone cross browser extension, without any 3rd party extensions or framework (to be as light as possible and not dependant on a 3rd party) that would load Jquery and a JS from a distant server and the ability to load it before or after the page is fully loaded.
I've read a lot of topics about the subject, but since IE10, Chrome 26 and FF20 are out with their new cross-link limitations, i was wondering if somebody had ressources, source code or tutorial about the following requirements :
I need :
Cross browser extension supporting (IE 8+ or 9+ worse case, Chrome
26+, FF20+, Safari)
Ability to inject a single JS hosted on another server. Inserts a script tag that references a javascript file in the head of the HTML
page and then be executed
Not be dependant on a third party extension (greasmonkey) or framework (Kango, Crossrider)
Ability to load before or after the page is fully loaded
This method allows me to customise the browser extension depending on the user's location and it also avoid having updates as the JS is updated on each page refresh.
I'm aware of the downsides, but i would like to achieve this.
I'm aware of cross browser framework like Kango or crossrider, but both don't fit me needs.
The closest example i could find is this How can I run a <script> tag that I just inserted dynamically from a BHO
but it only covers IE and as i got very little Csharp experience, i would like to see a full example to understand it properly and learn from example.
I would LOVE to have a few examples, even if it's not cross-browser (IE being the worst part for me).
Thanks a lot for your support !
Update1:
About Kango and Crossrider, Kango is 2000$ if you want to use IE and for Crossrider you're required to be distributed and monetized by them.
I've managed to code for IE and Chrome, but i was looking for an "elegant" way and figured it was the best place to ask given the level of knowledge of people on this site.
For the installer i currently use NSIS, but i'll test Wix too.
Finally i guess the only way for me would be to learn C++ and .net to get it to work with IE, but if anyone could provide more source code it would be great to test speed and compatibility and discuss here what's the best solution.
Why do Kango or Crossrider not fit your needs? Both frameworks allow you to manipulate the page's DOM (which is what you want):
Kango: Adding content script
Crossrider: documentation, example code
If you want to code your own solution, take a look at the relevant documentation:
Content scripts (Chrome)
The Page mod Jetpack API (Firefox)
Injected scrips (Safari)
Injected scripts (Opera)
Internet Explorer does not natively support extensions. It took me about 80 hours to create a stable and reliable IE extension which supports cross-site AJAX, a (preference) storage method and injection of scripts as early as possible in any frames based on its URL. I developed and tested the extension with Visual Express 2010 on Windows XP and Windows 7, for IE 8-10 (the extension might work on IE6/7, but I decided to not support these ancient and rarely used browsers).
First, I wrote an extension in C# based on LiveReloadIEExtension (a sample IE extension, which in turn is based on this Stack Overflow answer - see also this blog post). It was functional, but it required .NET 4, lacked support of frames, and it's relatively slow.
So, I decided to write an IE extension from scratch in C++. A good starting point is available at http://www.wischik.com/lu/programmer/bho.html: Sample code for C++ BHO, which changes the document's background based on key/mouse events. I've also learned a lot by looking at other code samples on CodeProject, topics on the MSDN forums, questions and answers on Stack Overflow, lots of other blogs, and the MSDN documentation:
DWebBrowserEvents2 interface lists several events which you use to find an appropriate injection point.
Scripting Object Interfaces (MSHTML) lists even more interfaces. You'll be mainly interested in the iHTMLDocument, iHTMLDocument2, ... interfaces.
After creating the IE extension, you want to deploy it of course. I used Wix toolset to create a MSI.
Since I don't really have a good idea for word to search with myself I’d like to ask you:
Is there some project, technology, w/e that enables you to build a 'browser' with a very slim ui. Just some CI and a customised "starting page".
I'm thinking of something like the Webkit engine (and interface) Valve/Steam uses for it's clients store page.
In what direction should I search for something like that ? How would one start implement something like that ?
Answers to questions:
We need this to provide something like a "Kiosk" application (for touchscreens) and shippable to our Customers. Running a browser in "full screen" is a temporary solution.
As of Platforms: Windows is absolutely sufficient for now, but Mac/Linux wouldn't hurt.
Prism looks nice so far but lacks the "shippable" part, e.g. I see no way of packaging it.
Take a look at Mozilla Prism. It's a "UI-Less" version of the Mozilla/Gecko rendering engine aimed at deploying web apps on the Desktop. It's also multi-platform. It might be fairly close to what you need, with comparably little work.
WebKit has bindings for many languages, is cross-platform, and is full-featured as a HTML engine. A bit of work capturing signals and calling functions will make it into any kind of web browser you like.
You could use Adobe Air, follow this tutorial and include your website within an iframe. That would allow you to build an executable you can ship to your customer.
Various graphics toolkit libraries contain some components which can display a limited amount of HTML. I've seen this in qt (a C++ GUI library) and in Java Swing, and have indeed built a tiny "browser" in Java within a couple of hours. Java Swing lets you attach a link listener so links can be made clickable and thereby jump to different URLs. Thus, my application could be made to work as a very limited browser.
This approach lets you display text, images and links; in the case of Java, there's even fairly good support for CSS styling. However, there's no simple way to make buttons and form fields work, and of course no support for manipulating the DOM or anything else done in JavaScript.
