How to programmatically get current directory of a Windows command line or Windows explorer?

Question

I'm writing a Qt C++ program on Windows and it has registered a global shortcut Ctrl+j . Whenever the user press Ctrl+j , the program's UI will show up. When the active window is a Windows command line or a Windows explorer and the user presses Ctrl+j , I want to get the current directory of the Windows command line or a Windows explorer. Is that possible?

For Windows Explorer you can write a BHO and communicate with it from your application. BHO - Browser Helper Object - will load into Windows Explorer process and can access anything, eg windows handles, text in the textboxes etc. We've done this for Internet Explorer.
