• Angel Dimitrov Both Async and Sync reads from the same Network Stream? (EXTREMELY STUCK!)

  Hi guys I'm really stuck! I'm programming a network heavy app with a TCP client in VB.NET 2005. I need it to have an async read of the network stream so that it can react to any impromptu messages sent by the server but also SOMETIMES have a syncronous read when the client has sent data to the server expecting a reply. I can have the two (async and sync) reads working independantly, but as soon as I try to use both the app hangs. I' ...Show All

• Dwaine Why do I have to XmlInclude derived classes in order to serialize?

  Hey Guys, Perhaps some of you braintrusts can shed some light on something for me. We built a web-app (nothing crazy, pretty simple) for a client using ASP.NET 2.0 Beta 2.  On the development machine, the .NET Dev server, it runs fine.  Does exactly what it's supposed to.

  We extensively use XML schema in our application, exchanging XML instances between the client and the server. We create typed dataset wrappers on top of the schema to speed up the development.
