Question

Task bar

How to make a program that opens other applications and can pin other applications to the taskbar?
For example, you need to open visual studio code, and for this you need to fix this program.
Simple taskbar.
Python.

Answer 1

You need to understand how it all works: what is the taskbar, how applications get there in Windows itself, and how each of these stages can be implemented in python.
Of course, you can take and tell all this, but it will be more useful if you yourself dig and understand, make your own code and, if something is missing in it or does not work the way you want, then bring your code and there will be something talk.

Answer 2

You don't need to pin it to run visual studio code.
These are two separate issues that are not directly related.
Googled on the first try for "python run external" and "winapi pin to taskbar".
Run from python Attach
to the panel in Windows
