GetWindowText does not read the columns for each row in the list view, why?

The option to read the details of the columns in the list view must be enabled (activated) in GetWindowText  on Windows 11, 10, ... etc. and MS Server OS!

1.) ... Read out columns for each column row in the list view!
2.) ... I want to create a C++ tool that reads the columns for each row!
3.) ... Advantages and disadvantages of such a list view selection tool!

1.) Read out columns for each column row in the list view!

(Image-1) Read the columns details from each row in the list view!

2.) I want to create a C++ tool that reads the columns for each row!
