Question

How to read the highlighted/Selected Text from any window using c#.

i tried 2 approaches.

Answer 1

That's because both Firefox and Visual Studio don't use the built-in Win32 controls for displaying/editing text.

It is not possible in general to be able to get the value of "any" selected text, because of the fact that programs can re-implement their own version of the Win32 controls any way they see fit, and your program cannot possibly expect to work with all of them.

However, you can use the UI Automation APIs which will allow you to interact with the majority of 3rd-party controls (at least, all the good ones - such as Visual Studio and Firefox - will likely work with the UI Automation APIs since it's a requirement for accessibility)
