Hi All!

is there any event or properti, which can tell if a chat window is in the background or active?

No not really but convo notifier and convo close sometimes work like that. Heres the links:

I like the second one.

Features:

    * Displays a toast message when someone starts a conversation with you.
    * Displays a toast message when someone adds you to his/her contact list.
    * Displays a toast message when someone removes you from his/her contact list.
    * When you already have a conversation window opened with the remote user, you won't get a toast message.
    * When you click the toast, a conversation window with the remote user will be opened. POSTED FROM THE THREAD

You can check: (code not tested)

code:

---

if(ChatWnd.Handle == GetForegroundWindow())
{
  // Window is on top.
}

function GetForegroundWindow()
{
  return Interop.Call("user32.dll", "GetForegroundWindow");
}

Working thanks

While it may work, it's not ideal. Checking the window state for a value may be more reliable.

My MSDN learning fails me right now...
