Is it possible for a Xcode "CommandLine application" (written in C++) to be launched with a custom URL scheme? I know you can do this with a Cocoa application, but would it be possible with C++?
It doesn't matter what language you use; it is not possible to bind a URL scheme to a command-line tool. The opening of URLs happens by an Apple Event to the application, not directly running the program with the URL (particularly since it may already be running, but this is true whether it is or not).
You could try embedding an Info.plist in the executable to give it a bundle identifier and declare its support for the URL scheme, which may enable you to bind the URL scheme to the executable. I would still be surprised if opening such URLs worked, but it's worth a shot.

I'm currently struggling with a problem regarding Deep Linking for a C++ application: the current goal is to allow the user to take certain action in the app after clicking on a browser link. I didn't have any issues managing to allow the user to open the application using this... The issue comes when I try to make the application do something specific, depending on the URL's "parameters". Here's an example, to better illustrate my current goal:
If I open this link from a browser:
mybeautifulapp://action=banana
Then, the application should go to the "banana" section.
If I open this other link:
mybeautifulapp://action=apple
It should go to the "apple" section.
However, I have no idea where to get the URL's parameters themselves. I.e., everything after "mybeautifulapp://". Currently, I'm able to get the app to open using any of these URLs. However, I'm not sure how to get the app to do something specific, depending on the URL's contents.
I initially thought that the C++ app would receive the URL in its Main function arguments. I tried parsing them, but turns out that nothing related to the URL itself ever reaches the Main function. If that's the case, then, where can I receive the URL in order to parse it? I found a lot of information for Android, iOS, and Electron applications, but nothing for C++ apps
Hei there, I'm not experienced at all in C++ as I need to start learning year the next year at my university, though, I've been creating a browser based game and I'm looking for someone to transform it into pc app.
Though, I'm wondering how to make that application send a http request via POST to a file on my webserver with the username / pw.
After all the tutotials I've been reading, I concluded that none worth spending my time with, because they all based on own database, and I'm looking for one that connects to a maestro server and requests the data from there.
This may not be the answer you are looking for, but you may consider two alternatives to a more pure C++ application.
If you already have a working browser game, try to take that same code and put the html/javascript/whatever in a file and give the file a ".hta" extention. It basically opens inside a browser to run your files, but it acts more like an application from the user's viewpoint. (And, as much as I hate Windows, they're pretty fun to create if I may say so). However, your source code with this option is easily read because it can be renamed to a text file (or html file).
You could use Visual C++ (or VB.net, which you have tagged to the question, as well as "Visual" C#) to create an application which mostly consists of a browser view. It could be a "standalone" application (however would rely completely on the .Net framework - may or may not be what you want) that basically accomplishes the same as the option above, but adds that you can "hide" your files inside your application.
Using the two above alternatives, you could make an application relatively quickly that would load your files, which I assume you have already created. Note that neither of the above alternatives will work on anything other than Windows OS's.
If the two above alternatives are not what you want, or if you have questions about either one, I'd be glad to attempt to help.
I've been able to find a friend that would do it in Delphi because I wouldn't want users to download net framework just for this ap.
So the program that would fit most for any apps is Delphi Prism XE (even if it's an addon of Visual Studio)
Are there any tools to run C++ applications written in QT on standard web browsers?
My C++ app has to run from a webpage, do some math, and return the result back to the webpage.
Check out NaCl (Native Client). No Qt, but you can use c++.
You can't. You can write the server side in a web app in C++, of course, but the Qt GUI framework is only for applications that show their user interface on the machine they are running on. (With the usual caveats in the case of remote X11 connections and so forth, but that won't help you for a web app).
I have read about a sample application like this. I think you can search for this term "Qt WebKit Hybrid application". In that example, the user interface is written in HTML and Javascript and the backend in C++. Even, the C++ objects ownerships can be transferred to Javascript. I'm not sure I'm correct but I'm partially correct.
EDIT:
Here is the link.

It's possible to compile C++ code to JavaScript using Emscripten, and then call compiled C++ functions from JavaScript, as explained here. This will allow you to run C++ code in a web browser or other JavaScript environment, without any additional plugins.
There is one more solution to this, you can write a browser plugin. I think that this is better then ActiveX and NaCl. For details on how to write plugins check this: How to write a C++ FireFox 3 plugin (not extension) on Windows?
Maybe you could embed the code in an ActiveX control.
I am planning to use yui or jquery ui as front end for native c++ applications. I found no bindings present for this purpose. Will it be feasible/possible to do this ? If it is so, then how shall i proceed? please suggest advice.thanks
#rwik - I can see your point and desire to do what you intend and I would presume it to be a wise move to be making at this point in time considering the vast facilities browsers bring to the table as well as other aspects... I know we are in September now and I have come across this pretty late, but this is also for others who have a similar problem...
As far as I know, descending from JavaScript in to C++ is pretty murky, mostly due to the heterogenous nature of Javascript engines [Rhino, Tracemonkey, Spidermonkey, V8, Caracan,Charka, etc] employed by different browsers. But there are indeed ways to do this - depending on how dirty you want to get your hands and, indeed, on your abilities...
If you were to go with Google as a browser, you should take a look at projects such as cproxyv8 - http://code.google.com/p/cproxyv8/ or v8-juice - http://code.google.com/p/v8-juice/ which both offer interesting facilities...
My preference however is with Mozilla - simply because of XML User-Interface Language (XUL) which, if you do not know, allows you to speedily create your own user interfaces by giving direct access to its layout engine. I.e., you can even do away with the browser look and have your own independent layout while still having all browser facilities at your disposal.
With respect to C++/Javascript interaction - projects should exist for all alternatives - it pays to check.
I wish you good luck if you haven't already solved this problem.
I'd recommend QT instead.
However since native C++ has nothing to do with GUI I'm going to assume you are making a library in C++. However Yui is basically just JavaScript as is jQuery. So if you're asking can a web page or script be a C++ application the answer is not really.
What you could do is create a web service which uses your C++ library and exposes an interface for your web based application to call it indirectly.
One way to accomplish this is to embed WebKit into your application and provide your custom C++ functionality via a plugin. Both the WebKit framework on OSX and the Chromium Embedded Framework on Windows allow this style of application development. This allows you to write a UI using local Javascript/HTML files without the need for a webserver.
There are no direct bindings in JQuery and YUI because these libraries run in a web browser. Thus unless you’re planning to write your own browser plugins, the integration with the C++ will happen at the webserver that serves the data to the browser.
You could feed the data from your C++ code directly into JQuery/YUI by building web services directly in C++. But you might want to build a web application that will be serving your JQuery/YUI pages and that act as user interface controller (like in the MVC pattern). Web application languages like Java, PHP, etc. all have ways to call native code. Java has JNDI and in PHP you build extensions that link to C++ code.
Is there any browser I could embedd in C++ application on Windows?
I need all features typical browser has (HTTP client, cookies support, DOM style HTML parser, JavaScript engine) except rendering.
Because I don't need rendering capability (and that's rather big part of a browser) I would prefer a browser with non monolithic design so I wouldn't have to include rendering stuff into my project.
It would be nice if it had C++ rather than C API.
I need this embedded browser mainly because I have much trouble finding C++ HTML parser which could handle broken HTML like browsers do.
If you know any, please answer Library Recommendation: C++ HTML Parser SO question or at least vote on it to increase a chance someone will give a good answer.
Sounds like all you need is something like libcurl which is an HTTP library and will let you do GET/POST/etc.
When I think browser I generally think rendering/JavaScript and not HTTP library.
Edit
In that case I'd look at WebKit (which I think has a C++ API) and hope you don't have to pull too much in.
Edit Again
On second thought (since rendering is such a big part of what browsers do), you might be better off using a stand-alone JS engine like SpiderMonkey and a stand-alone XML parser like Xerces-C (plus maybe tidy to make your HTML into XML).
I'm a bit confused by your question regarding embedding a web browser for which you don't need rendering capabilities. A web browser is rendering web pages by definition, unless you just need HTTP and XML with JavaScript capabilities which is a subset of a browser functionalities?
If you need a web browser to embed in your C++ application, I would suggest to consider Qt that comes with the WebKit plugin. It is C++, LGPL and has a very nice IDE (Qt Creator). I tried Qt with Qt Creator on unix (Ubuntu) and it was very impressive. The debugger is a bit light but it is just the first version. The adapter of Qt into visual c++ 2008 is now free.
You might also want to check out Awesomium-- it's free for non-commercial use and has all of the features you're looking for (if you don't need rendering, simply don't use it).
There is a project called CEF = The Chromium Embedded Framework - it is:
a simple framework for
embedding Chromium-based browsers in other applications. It is a
BSD-licensed open source project founded by Marshall Greenblatt in
2008 and based on the Google Chromium project. Unlike the Chromium
project itself, which focuses mainly on Google Chrome application
development, CEF focuses on facilitating embedded browser use cases in
third-party applications.
and yes:
The base CEF framework includes support for the C and C++ programming
languages.
Including javascript support and html parsing makes this non-trivial task - you have to use one of the available browsers.
IE is usable through its COM model - you can create instance of it in your window be it invisible or not and call its javascript/html capabilities.
It has been designed to be used like that since the beginning and certainly it is working fine.
The other options are:
Gecko/Mozilla - a couple of years ago it wasn't usable like this, currently I think it is.
WebKit/V8 - no public API has been released for chrome yet, you could use webkit itself, but it doesn't have javascript engine. Another option is to take a look at the Chrome codebase and see if you could get out of it what you need.
I would probably go for IE, since it is maybe the easiest option and I have already used it. The other options seem to me more like building a browser instead of just using it.
How about Gecko ? You may not need the entire engine but you may find some its components useful like SpiderMonkey which is a JavaScript engine written in C.
I'd recommend picking up Qt for C++ programming. It has a built-in library that embeds Webkit with all the bells'n'whistles, and Qt is a great C++ library in general.
Old question, I know, but take a look on

IActiveScript and family COM interfaces allows script execution (not only JS, any language that registers as script interpeter, for that matter) in-memory.
