This is going to be PInvoke city…

You’ll need to PInvoke the following API’s in User32.dll

Win32::GetForegroundWindow() in returns the HWND of the currently active window.

/// <summary> /// The GetForegroundWindow function returns a handle to the foreground window. /// </summary> [DllImport('user32.dll')] static extern IntPtr GetForegroundWindow(); 

Win32::GetWindowThreadProcessId(HWND,LPDWORD) returns the PID of a given HWND

[DllImport('user32.dll', SetLastError=true)] static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId); 

In C#

Process.GetProcessByID() takes the PID to create a C# process object

processInstance.MainModule returns a ProcessModule with FileVersionInfo attached.
