How can i solve this error in my code C++ - c++

This error makes my code wrong & I can't debug my code correctly.
This is my screen when I am debugging my code:
I can't understand the error. What is it and how can it be solved?

It means you do not have SDK (and tools) for Windows XP target compilation.
You either need to:
change platform target of the Project ( Yer Project -> Properties -> General -> Platform Toolset)
or install that feature (Control Panels -> Programs and functions -> Visual Studio X -> modify -> select "Windows XP support for C++")

Visual Studio 2019 Always run OLD version code

I tried many things that searched on google.
listing I had.
Project -> Property -> Debugging -> Debugging = Auto
Build -> Configuration Manager -> Check OK "BUILD" option ( Also I checked solution platforms and configs. )
Tools -> Option -> Build & Run -> Always Build. and Uncheck "just startup project & dependencys"
Those are what I did to build every pressing F5.
It doesn't work. even though I restart computer or visual studio.
What should I do for it?
ps. My Project is Visual Studio C++ (Empty)
I had the same problem. Looking for days but finally i found a solution.
The first step is to completely delete Visual Studio (installer as well,yes) and then install it again.This time check on "general options" and not "recommended for C++" in the beginning of the installation(Its where you choose the color of the IDE).I know it's sounds..weird.Let me know if it worked for you too!
This may be due to your visual studio having settings that launch the old working code if the current code has some issues.
You could change that setting using the below steps:
Tools > Options > Project and Solutions > Build and Run
Do below settings on the left pull-down menu
On Run, when build or deployment error occurs > Do not launch

change microsoft compiler from vc14 to vc12 in devenv.exe

I compile command line most of my applications using msvc12's vsvarsall.bat and setting the platform. Now I have a project that comes with a visual studio solution and it compiles with msvc14. To keep compatability I would like to compile with vc12. How do I switch compilers inside devenv.exe?
Open the project in msvc, then go to "Project -> Properties -> Configuration Properties -> General -> Platform Toolset".

Best way to start a project: OpenCV + GUI (C++)

Hey this is my first question here on stackoverflow, allow me to add that i'm a newbie in programming.
Which would be the best or the "right" way/approach to start a OpenCV with a friendly GUI (not console based) software.
Which IDE should i be using to achieve this ?
I have Visual Studio 2012 and Qt.
1.Empty CLR Project
File -> New -> Project -> VC++ -> CLR-> CLR Empty Project
Then:
Project -> Add New Item -> VC++ -> UI -> Windows Form
2. MFC Application
File -> New -> Project -> VC++ -> MFC -> MFC Application
I've also searched for Emgu CV which seems to be working better with C#.
What about Qt ???
Thank you in advance
Try Code blocks or Visual Studio 2013.
I would prefer VS2013 if I was you.

How can I create a C++ project in Visual Studio 2010 Ultimate

I was new to Visual Studio and I want it to debug some of my c++ files.
The VS 2010 Ultimate was already installed in my lab system.
Now to debug after referring to internet and also here I came to know that we need to start a new project as below
File -> New -> Project -> Visual C# -> Win32 -> Win32 Console application
But in my VS there was no Win32 under Visual C# but there was Windows in which there was Console application, which I selected.
Then we need to add the C++ files under the source files directory. But I didn't find any such directory in this console application.
Is there any problem with installation or configuration.
Can anyone please help me.
the correct path to start a win32 C++ console project is
File -> New -> Project -> Visual C++ -> Win32 -> Win32 Console application
and if you don ´t find path it mean that you.have a custom setup.
find your setup DVD and/or use Add and Remove program to " modify " the setup. When installation program ask for the component you need check the C++ box. finish the setup and and after you will have a specific section for c++ project ....

How do I create a native application using Visual C++ 2008?

I am getting started in C++. How can I setup Visual Studio 2008 to create native (not managed) code?
Choose a Win32 Project.
If you're just getting started you probably want a Win32 Console Application, and not a Win32 App. File -> New -> Project -> Visual C++ -> Win32 -> Win32 Console Application
When you create the project itself you'll probably want to click Next before you click Finish, and select Empty Project so that VS won't add a bunch of junk to your project for you.
File -> New -> project (maybe go to other lang if you see c#) -> visuall c++ -> win32
You can choose other types there it still be native.
(like mfc, but I doubt if you really need something other then the basic win32)
In the new projects dialog, choose any project type under the Visual C++ group. You'll need Visual Studio Pro, or Visual Studio Express for C++.
