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

I was trying to make a webscraper in C++ (I know I could use some other language but I'm just trying to learn). There's a webpage I'm trying to get the html code to but the page changes after a second or two with the links I want. How do I make the program wait until sometime to return the html?
Edit: I want to make a curl call once and then wait some time and then do another curl call to the same webpage after some time. (Not open the link again as it would give the same page)
You have three options:
investigate the site and figure out how the javascript code is changing the page, then replicate that in C++ (either by hard-coding a URL or parsing parts of the page),
embed a full browser engine that understands JavaScript and click the link after it changes, or
abandon C++ and use a dedicated scraping tool like CasperJS or Scrapy or wring or ...
I would inspect the page and see if you can make option 1 work, but option 3 is by far the easiest approach.
I have this website that I'm editing for a friend and they want to get rid of this message at the checkout screen but their boss doesnt know who implemented it. Its an error message at the top in read that says "If you are having trouble checking out, please contact us at sales#cbobaby.com" and is in the check out page. This is an open cart website and I only work with wordpress sites so I'm having trouble figuring out where the source of the message is coming from. I've dug through some of the template files in the theme and I can't seem to find or delete anything that gets rid of it. My question is if there is anything in Chrome dev tools that would help me identify the source or template it lives in? I only use dev tools for adjusting css but I know there's so much more you can do it with. Thanks.
No, DevTools can't relate your front-end code to what generates it for the DOM. For the exact same reason we are unable to persist edits in the DOM to your source.
You need to use grep, or some code editor with "find all" functionality and look for some part of the string. If that fails, search your database and see if it is coming out of there. You can then either edit the database and hope nothing breaks, or try to back-track through the application logic to find where is calling that part of the DB. It should give you some ground as to where to look.
In the Sources tab, you can see the resources, that are loaded when you are on a particular page. You can also use the Inspect tool in the Elements tab to find the element that hosts that bit of text to narrow things down in your search.
To add to this, if content is generated on the server side, the resources you see will likely be a merge from multiple generated sources, e.g. with templates in your case. You can search your solution for aspects of the DOM elements you see in Chrome Developer Tools, but look for the static parts instead of the dynamic parts. For example, the text itself won't be part of the template file, a placeholder will exist - a CSS class could be useful.
I was looking into trying to get my C++ application to do the following:
Open internet explorer
Open a webpage
Enter a name and password into specific forms in the webpage
Click the submit button on the webpage to open a new page
From my searching on the Internet it seems like using COM may make this possible, although I may be incorrect on that. I am doing my best to learn COM at the moment but some help would be great. I'm looking to do this without using MFC.
I have noticed this question which I kind of what I am looking for but I am having trouble understanding the suggested solutions. For example, I do not have a IWebBrowser2 option in my toolbox.
EDIT:
To make my question clearer, I had this task complete in a C# version by simply running a coded UI test but this will not work with C++. I am looking to open IE (not in the application itself), find the username and password forms, pass them string, then find the submit button on the page and click it.
This is very possible from c++. You will have to dive into the winapi to do some Keystroke stuff as well as window handling.
I'm not going to go into all of the code, but you have to do something like the following:
Start ie (if you give it a command line arg with the webpage, it will
open that page).
Make sure the ie window is focused (either just wait
if you want to keep it simple or use window's api to go through each
open HANDLE and find the window you want)
Use SendInput to send an Alt + D (to gain focus to the url bar, in firefox it will be a CTRL + L instead)
Use SendInput and javascript injection to modify the DOM as necessary
You can also submit the form (after everything is as you want it) using the above JS injection capability.
Yes, it is possible, but you have to embed a web browser control in your application, and it is not straightforward (I don't think you can automate DHTML in an external instance of Internet Explorer via COM).
I see that you don't want to use MFC, and this complicates even more the problem. Perhaps you can do it via ATL, I advise against even trying to do it without a framework.
If you could use MFC, then you could use a CDHtmlDialog form and access the underlying COM interfaces to automate the actions.
In the past, I developed an MFC application that used HTML as its user interface, but I used the CDHTMLView class that you can find here: http://www.codeproject.com/Articles/1783/Integrating-DHTML-into-MFC-Views
You can use this as an entry point for learning how to deal with DHTML events and how to play around with the IWebBrowser2 interface.
You should really take a look at WebDriver which is able to do exactly what you are describing. See (http://code.google.com/p/selenium/wiki/InternetExplorerDriverInternals) for more information about the InternetExplorerDriver internals. Even if you are not able to use the project directly, you can certainly browse the source to get a better idea of how what you want to do can be achieved.
What you want to do makes not much sense.
There are many APIs available to embed a browser view into your program. For example Qt offers this.
Then you can just do your HTTP POST request yourself and display the answer you get in your browser view.
That is a much cleaner solution.
Pro tip: Don't use Internet Explorer.
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.
This is my first substantial MFC application.
My out-of-the-wizard MFC app wants to open a blank, new file of the type I specified for my app, when it starts, but that's not meaningful for my application. I want my app to open some connections to some remote sites and get data from them.
Where should I consider interrupting or overriding MFC's default behavior? I could subclass CWinApp::ProcessShellCommand(). I could modify the CCommandLineInfo object it works on. I could excise the whole command line processing and just call my go-get-the-data functions. I probably should just altogether excise the whole document-as-a-file related processing. I'm not opening or saving any files, except debug files or logs that are outside of the UI's concern. The only saving or collecting of local information is via a database, to which and from which I handle the serialization myself, so no CArchive, either.
I've got all this code but it's hanging in front of me disjointed and disintegrated. I'm too new to this and there's too many alternatives. Some simple guidance for a simple beginner is what I'm asking for.
So, if you'll say, sure, lop off the document-as-file handling, tell me, please, where I need to go to do that bit of surgery, I can see it's not just one object that'd be affected. And so forth. Thanks.
You might consider generating a new application, but when you do, tell it that you want a database application without file handling. Even if you don't use its database capability, it'll produce an application whose basic layout is set up roughly for what you're trying to do, so you'll basically just substitute your database interface for what it provides, but won't get involved with trying to rip out file handling and such that's apparently irrelevant for your program.
I found an answer with respect to modifying default file opening. While I made the database app Coffin suggested, I saw the phrase "storing database objects in views" and I rather aimlessly searched MSDN with that. If I was going to try the database app approach and do my own serialization, I had to learn about this.
I thus found an MSDN page concerning handling the file menu in database apps, which discusses how to alter and even disable the OnFileOpen command. It's applicable to OnFile New and it is the approach I was hoping for.
