The values in the file did not show up in VS, Project Properties, Debugging. This example assumes the script is long-running and omits the --wait-for-client flag, meaning that the script will not wait for the client to attach. Once you've tested the Debug version of your application, you should also compile and test the Release version. Expressions that you enter in the Debug Console are run on the remote computer as well. Following this guide, I set up the argument in the launch.json file: But when I press on Debug, it says that my argument is not recognized and Visual Studio Code says: As Visual Studio Code is using PowerShell, let's execute the same file with the same argument: So: the same file, same path, and same argument. # Pause the program until a remote debugger is attached, python3 -m debugpy --listen 1.2.3.4:5678 --wait-for-client -m myproject, "Python: Current File (Integrated Terminal)", "Python: Current File (External Terminal)", "/Users/Me/Projects/PokemonGo-Bot/pokemongo_bot/event_handlers/__init__.py", "${workspaceFolder}/pokemongo_bot/event_handlers/__init__.py", 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope, Configure IntelliSense for cross-compiling, Tutorial - Configure and run the debugger, Configuring Python environments - environment variable definitions file, Debugging by attaching over a network connection. You can test this with a useful debugging feature called a conditional breakpoint. They just pass the arguments string to the Python parser, and things can be done easily. For a short walkthrough of basic debugging, see Tutorial - Configure and run the debugger. Had the same issue but both declarations mentioned above didn't work. If clicking the "Debug python file" doesn't pass the arguments then add "purpose": ["debug-in-terminal"] in the launch.json file. Have you ever had the need to start Visual Studio from a piece of code and the code you needed to debug (the reason why you open Visual Studio instance in the first place) needs command line arguments. VS Code will try to automatically detect your debug environment, but if this fails, you will have to choose it manually: Here is the launch configuration generated for Node.js debugging: If you go back to the File Explorer view (E (Windows, Linux Ctrl+Shift+E)), you'll see that VS Code has created a .vscode folder and added the launch.json file to your workspace.

In the terminal, start Python with the script, for example, python3 myscript.py. Make sure to pass the appropriate command line options to the debug target so that a debugger can attach to it. Optionally a preLaunchTask can be specified that is run before the individual debug sessions are started. Stack Overflow . Then you do it like "args: ["--city", "Auckland", "--year", "2000"]. Enter currentDate = DateTime.Parse("2019-11-16T17:25:00Z").ToUniversalTime() at the bottom of the Debug Console window and press the Enter key. According to your description, please try to follow these steps: 1. open vs -->select menu" Tools "--> Options --> Environment --> General -->uncheck the checkbox Optimize rendering for screens with different pixel densities.. 2. close the vs and reopen is and then open your project to check whether the issue persists. There is more than one way to configure the Run button, using the purpose option. VS Code debuggers typically support launching a program in debug mode or attaching to an already running program in debug mode. Prepare to debug console projects - Visual Studio (Windows) Continue program execution by selecting the Continue button in the toolbar. 3.
