RE: [flexcoders] Re: Socket communications in Flex
Are you sending the magic character that flash interprets as the end of a piece of data coming in on a socket connection? It's been two years since I did this, so I can't remember what that character is, probably either a null or a newline. That's the only special thing I remember doing with a socket server, if you don't do that then it can appear as if it's not working. -Original Message- From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of markgoldin_2000 Sent: 15 February 2009 16:50 To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Socket communications in Flex I was able to create a server socket using VB code.

Re: [flexcoders] Re: Socket communications in Flex
It's \0 or null character for the XMLSocket class. This limitation doesn't exist when you use the binary sockets.
Re: [flexcoders] Re: Socket communications in Flex
Firewall? Is the port you're using open? Is the data event firing at all? If so, what's in it? If not, either your server is not serving data like you think it is, or the data can't get to your flex app because there's something in the way.

RE: [flexcoders] Re: Socket communications in Flex
Yes. I wrote a socket server in VB.Net that talked to a Flex app. It was years ago but I'll send you the code if you like.
