I am trying to get full path of window which is on top.
My application is in background and when user press specific key then i want to know the path of current window which is On top.

I try following code but this code is showing my own application path.

What I have tried:

C#

protected override void WndProc(ref Message m)
        {
            base.WndProc(ref m);
            if (m.Msg == 0x0312)
            {
                Process currentProcess = Process.GetCurrentProcess();
                MessageBox.Show(currentProcess.MainModule.FileName);
            }
        }

There is no such thing as "path of window".

Well...yes, it will.
There are two problems here. The first is that in order for you application to be activated by a key to find out which window is on top, it has to have the input focus. which means...it's on top...:laugh:

Secondly, if you look at the documentation for Process.GetCurrentProcess Method (System.Diagnostics)[^] it returns a process associated withteh currently executing code: i.e. the code that is trying to find out which process is tip most - this will always be your application!

Pretty much, you can't do what you want - though the link will show you how to get all processes on your system - unless you can install a Global Hook which can trap out the key at a level much, much higher than your application. While this can be done (Processing Global Mouse and Keyboard Hooks in C#[^] shows how) it's not something for a beginner to attempt - mistakes can leave your system seriously unstable!
