According to this link, .natvis files can be used to visualise native objects. Specifically, I would like to be able to inspect Eigen::Matrix objects using this .natvis file.
However, the link above does not contain any information on how to actually use a .natvis file in VS Code. Is it possible using a custom .natvis file?
Here is my launch.json file for reference:

I want to break when and where an exception occurs. However, I cannot find where to enable this. There are no exception checkboxes in the breakpoint panel.
Running on windows 10 using mingw g++ v11.2
How do I enable break on exception?
I've just started to use VSCode, I meet this error and try some ways to fix but it doesn't work.

Problem fixed by doing these steps below.
Go to Windows Control Panel (You can do this by opening File Explorer and in the path type 'Control Panel' (without quotes) and hit Enter);
From the Control Panel, click on 'Clock and Region'.
Click Region. A new screen will open.
In the screen that opened, click on Administrative and search for the button "Change system location".
Check the option: "Beta: Use Unicode UTF-8 for world language support"
Restart the computer.

the problem was with Launch.json
the path files should not have any spaces like in my case "prog files" was error and i replaced and rename folder with "progfiles"
"program": "D:\\Progfiles\\vscode\\hello.exe",
"args": [],
"stopAtEntry": false,
"cwd": "D:\\Progfiles\\vscode",
"environment": [],

It was GDB.exe here earlier, But it said it couldn't find it , Even I couldn't find it..
So I put gdb32.exe as i was able to find that out , But it still didn't debug anything
i am fed up of this problem now...
Code Blocks says Please specify executable path,It can't be found
Please help, Thanks
Code::Blocks can be installed without MinGW, which is okay as MinGW-w64 is much better maintained. But MinGW-w64 needs to be installed separately.
You can download a standalone MinGW-w64 from https://winlibs.com/ and the site also explains on how to add this compiler and debugger to the settings.
I have Problem in debugging c++ programs in Visual studio code. Although, debugging was working before. I had not change any configuration or setting. When i opened visual studio code today then i saw that error.

I have not changed anything in system/vc code/ configuration etc.
Then, why debugging stops working.
The program setting specifies the program you want to debug. Here it is set to the active file folder ${fileDirname} and active filename with the .exe extension ${fileBasenameNoExtension}.exe, which if helloworld.cpp is the active file will be helloworld.exe.
The main problem is vccode is not able to find the current file for debugging.
These are some links that might work for you.

Configuration
Over the weekend I had installed a gcc through the MSYS2 bash. I set it up in VS code and have it working properly. I even had the GDB working (yes I know this is a debugger). But, my main question is, is it possible to use the debugging function in VS code to debug rather then GDB. Pressing F5 it pulls up the launch.json file and gives me launch: program 'enter program name, for example c:\School\a.exe' does not exist .After some research I see you give it a file to the args to allow it run in debugger. When I do this though I can't seem to either give it the right file or make it work overall. I am also using a.exe rather than a.out. I'm unsure if this has effect.

VS Code does not have an internal debugger (see here). You need to use GDB or the visual studio debugger (if you have the latter).
In your launch.json you need to modify the entries:
"program": this is the path to the program you want to debug, i.e. your compiled program (can be a relative path to your project folder)
"miDebuggerPath": this is the path to GDB
"args": these are arguments, you want to pass to your programm for debugging purposes, i.e. you can leave this blank
So the launch.json file for you would look something like this:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}\\CSE340\\project2\\main.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": true,
"MIMode": "gdb",
"miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe", // Path where your gdb.exe is located
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
]
}
]
}
${workspaceFolder} is a path variable to your workspace and seems to point to C:\\School\\, so maybe you'll need to modify the value of "program" to point to the application that you want to debug. You could also specify the absolute path to your program.
Also, do not forget to compile your code with debug-flags (-g), these are needed by GDB in order to step through the code. For example:
g++ -g main.cpp -o main.exe
