[API WIN32] Inserire il testo di una editibox nella listview di un'altra finestra?

giovannigiorgio · 31-03-2010, 09:13

Ciao a tutti,
Ho una applicazione multiwindow. Voglio inserire il testo di una editbox di una finestra nella listview contenuta in un'altra finestra. Non riesco a trovare il modo. Qualcuno mi aiuta?
Grazie.
Vi posto il codice funzionante ma senza quello che voglio io.

Codice:
