I'm rewriting an old product (written in C++) as a new VSCode extension. The UI part is going to be redesigned and implemented using Typescript.
Is it possible to somehow salvage the functionality logic and invoke it somehow (e.g. wrap it in some library and use it)?
If it's possible, would the solution work for both Windows and Linux VSCode use?

I am completely new in using SKIA as well as WebAssembly. I have build SKIA library on windows and currently using it with C++.
I heard of WASM which can convert C, C++ codebase to run on browser. I have tried that too with some sample native code written in C and achieved it. This is really awesome.
Now I am trying to build a framework which can run natively as well as on web with the same codebase. Is it possible to do with SKIA ? If yes, How can I do it ? There is very less information regarding this on the internet which is not that clear. So I thought of getting some information from here. Any help or pointers on this would be appreciated.
The goal is to write whole code using C++ and SKIA, build it on Windows. And I want to use WASM to convert the same code to run on the browser. How ?
SKIA is using D3D or OpenGL to render, it also create a Window using system calls. WASM does not have any "system" calls, like any OS has. You have to virtualize all such calls as WASM module imports API.
I have some codes in Qt Creator that work properly. I need to use this codes but in win32 application in .net framework. Does anyone have any idea how can I do this? I am totally new to Qt and do not know how to use this useful codes in c++ project?
I appreciate any help in advance
I think I could not get my message across. Qt is c++ but It has some differences with the native c++ app that we use in .net framework. so I can't just copy all the codes in my project to run it properly. Can we make a dll or library to use this qt code in .net or not? and how can I do this?
I really need help. Thank you so much
For almost all cases, you do not want to mix .net and Qt in same application. It's less work to just take the logic and rewrite it for .net (managed C++ or C#).
Next best option might be to keep the parts separate and have them communicate through some IPC mechanism.
This is, because any non-trivial Qt code depends on it's own event loop, so getting the existing Qt code play nice with other event loop is always a hassle, and trying to get it play nicely when actual application is managed .net code... No, just no, unless you have a very compelling reason, are expert on both Qt and .net, and have extra time to make it work right.
I'm not sure if you don't know how to download and install Qt or how to create a Qt project in Visual Studio IDE. Try this installation guide.
Do you want to link the Qt library to your win32 c++ app? I think you should build the qt source code first with your win32 compiler. I think you could include the qt header and link the library as normal win32 library to your application after that.
I am planning to build an app in C++ for ipad. I have never build any app for ios. I want to know whether is it possible to write a C++ app using Lucene library in ipad. Can i write the code in visual c++ and compile it in xcode. Can i use the same code to work in mac os as well? I really wanted to build the app in Java so it works every where but unfortunately I pad doesnt support java.
Please provide me some good suggestions to build this app.
Thank you.
No. You can't build for iPad in Visual Studio.
You can include C++ in "Objective-C++" files, named .mm, but you will have to learn a minimum of Objective-C in which to include your C++ code.
As for using the same code for mac, it depends on how well you separate your logic from your display code - you can reuse some code, but you can't simply hit "build for Mac" and have iPad apps magically run on the Mac. You'll have to, at the very least, build a totally separate interface.
Building apps for iOS, etc requires some simple steps :
Buy a Mac
Learn some Objective-C
There is no other way around that makes sense.
I want to use Xcode as my major complier for C++. However, I'm having a hard time starting programming. Which kind of project and target should I select if I want to write some applications with user interface?
I've been coding with Xcode for one semester but all the projects were half-done the time I saw them, so I really don't know how to start by myself. I tried the Command Line target but it did not seem to generate an application.
Sorry for asking these naive questions. Thanks for any help!
You can start with a barebones project by going to New -> New Project -> Application (under Mac OS X) -> Command Line Tool. This will give you a basic main() function that you can enter code into. This is what I use alot of the time for algorithm practice.
If you want your app to use a GUI framework, you can either choose the template that #sblom suggested and make a Cocoa Application (here is a good guide to get you started), or you could use a C++ framework such as wxWidgets or Qt (usually used with it's own IDE, Qt Creator).
Note that while Cocoa is in Objective C, you could just as well program in C++ for the core functionality of your app, just make sure the implementation files have a .mm suffix.
You'll need to use Mac OS X -> Application -> Cocoa Application. Unfortunately, it won't exactly be in plain ol' C++, although you can use C++. You'll have to use Objective-C to make actual calls into the Cocoa Framework (well, there are ways to make the calls using straight C/C++, but that's really cumbersome.)
I will highly recommend to use QT but not WX.
We use WX for years in our Valentina Studio application. And we going switch to QT asap. Reasons are that WX on MAC has weak progress. Troubles with Cocoa support. QT looks much more better choice ...
I have to create an application for testing that is relatively simple. If a user plugs in a device into a USB (hid library), the form will say "Pass". If no device is detected, it will say "Fail".
I want to create the app to run on WinXP+. It must be a forms application as it needs to be visual and have colors. The biggest requirement for me is that it must be stand-alone (a user just double clicks, the file and it opens, no installation). I need to avoid installing any extra .dll files and want to avoid the .net framework all together. It has to be written in C++.
So my question is, what are my options? I am new to Forms applications and the only forms application I have written required the .net framework.
From my research, Visual C++ seems out of the question as it requires .net for Forms apps. What about Turbo C++ by Borland? It seems outdated, but can it do the job?
I would suggest Borland C++ Builder 5 or 6. Visual C++ lacks the functionality to create C++ form apps, if we dismiss MFC
I'd say Visual C++ would probably still be your best option. A standard simple Win32 C/C++ program using only the native API will should suite your needs just fine. If you're targeting XP+, then the only dependency would be "msvcrt.dll" which is included with Windows by default.
Edit: This article on MSDN should get you started in the right direction.
What you're talking about is C++/CLI, it's microsoft's dialect of C++ that requires a .Net framework. Please distinguish it from real (native) C++, which can be used to create what you want to. Visual C++ is perfectly fine, just make sure you don't create a .Net project.
Forms are a .NET library. It's not Windows or anything like that, you can use the native GUI libraries in Win32 with no problem or any native wrapping of them. You can implement this in native C++ easily in Visual Studio.
If you're looking to create the application in a rapid fashion (i.e. stock UI components that you can drag and drop onto forms), my experience is that Embarcardero C++ Builder effectively solves that problem space.
I like Visual C++ but it's not a great environment for rapidly creating forms based applications. I want to emphasize that I'm referring to Rapid Application Development (RAD) tools. There are plenty of great C++ IDEs and libraries for creating forms based applications and all of them should be able to create standalone exes.
