Yes, i'm actually making a code, you'll have to use cwnd.dll, it might be the same thing as your dll, cwnd.dll have a lot of more feature but the help file is in french...
Edit : in fact you will have to play with this :
Cwnd.dll 1) open you dialog
2) dock the dialog to the channel window with :
//noop $dll(path\cwnd.dll,setParent,$dialog(your_dialog).hwnd $window(#your_channel).hwnd)
3)Use dialog -s to move your dialog where you want (dialog -s dialog X Y -1 -1)
4)Use this :
//noop $dll(path\cwnd.dll,remWindowLong,$dialog(Your_dialog).hwnd style WS_DLGFRAME) .
I hope this help
