Titolo: [?] Docking al desktop

Salve a tutti,
avrei bisogno di fare il docking di una finestra direttamente al desktop, di
modo che la mia finestra si 'incolli' ad uno dei bordi dello schermo,
riducendo l'area utile dello schermo, un po' come è in grado di fare ICQ
all'occorrenza, oppure semplicemente come la traybar se la mettete sempre in
primo piano. C'è qualcuno che ha un esempio oppure un sito da cui
scaricarlo? So che questo argomento è già stato trattato (almeno una volta,
me lo ricordo io stesso), ma purtroppo non ne ho trovato traccia... quindi
scusatemi se ho ripostato la domanda.
grazie, assa.

grazie mille, ma purtroppo non è quello che cercavo...
questo esempio va benone se si vuole fare il docking di una form ad un'altra
form, ma non per quello che voglio fare io...
grazie lo stesso, assa.
