[Paulo Margarido]

hello,

i'm using a componente that implementes a twain interface, i name it ScannerLib

where i have a class

Twain : System.Windows.Forms.Form, IMessageFilter

and in the other aspx class i use it to interact with a scanner (Mustek's Bear Pawn )

i can start the DS, negotiate with him some capabilities, but when i ask for Aquire its supost to receive some messages passed by the scanner
than i could PreFilterMessage this messages in order to get the scanned image.

but i'm missing any step!
