How to get active window that is not part of my application?

Question

How can I get the Window Title that the user currently have focus on? I\'m making a program that runs with another Window, and if the user does not have focus on that window

Answer 1

Use GetForegroundWindow to retrieve the handle of the focused window and GetWindowText to get the window title.

[ DllImport("user32.dll") ]
static extern int GetForegroundWindow();

[ DllImport("user32.dll") ]
static extern int GetWindowText(int hWnd, StringBuilder text, int count);   

static void Main() { 
     StringBuilder builder = new StringBuilder(255) ; 
     GetWindowText(GetForegroundWindow(), builder, 255) ; 

     Console.WriteLine(builder) ; 
}
