Question

I’d like to know how to grab the Window title of the current active window (i.e. the one that has focus) using C#.

See example on how you can do this with full source code here:

http://www.csharphelp.com/2006/08/get-current-window-handle-and-caption-with-windows-api-in-c/

[DllImport('user32.dll')] static extern IntPtr GetForegroundWindow();  [DllImport('user32.dll')] static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count);  private string GetActiveWindowTitle() {     const int nChars = 256;     StringBuilder Buff = new StringBuilder(nChars);     IntPtr handle = GetForegroundWindow();      if (GetWindowText(handle, Buff, nChars) > 0)     {         return Buff.ToString();     }     return null; }
