[Mono-devel-list] NetworkStream

[Rafael Teixeira]

Did you compile with VS.NET/vbc in Windows, or is compiling with mbas in Linux?

If so, mbas currently doesn't automatically initializes local
variables as vbc seems to do so you need to be explicit:

                  Dim llogReadEverything As Boolean = false

Hope it helps,

Just because DataAvailable is true does NOT mean that you may be able to read ALL the data you are expecting from the stream, it might not have arrived yet, and as you are expecting to be able to read it all it might return 0 (I think it should block though, which is why it must work on .NET)
> 4.) After some of the diagnoses above, file a bugzilla report.
