LocalConnection uses shared memory and AMF0. You can connect from VB.NET but if you don't have any particular/special reason.....then avoid doing it (and use ExternalInterface as it was recommended)
(I personally did this with c#/fluorine and using the docs from here http://osflash.org/doku.php?id=localconnection but abandoned the whole idea) Zoli -----Original Message----- From: Francis Cheng [mailto:[EMAIL PROTECTED] Sent: Thursday, April 27, 2006 2:51 AM To: Flashcoders mailing list Subject: RE: [Flashcoders] LocalConnection from SWF <-> Visual Basic? David is correct, LocalConnection does not write to a file--it uses shared memory. I'm not an expert on LocalConnection, but it doesn't surprise me that you can experience some latency if a dozen SWF files are all sharing memory with a single gateway SWF file. The beleaguered gateway SWF would have to manage a dozen different shared memory allocations (and I believe there is polling involved). As for the original question about communicating with a VB application, if you can publish for Flash Player 8, ExternalInterface is the way to go.
