winsock

C# socket server, which has roughly 200 - 500 active connections, each one constantly sending messages to our server.

About 70% of the time the messages are handled fine (in the correct order etc), however in the other 30% of cases we have jumbled up messages and things get screwed up. We should note that some clients send data in unicode and others in ASCII, so that's handled as well.

Messages sent to the server are a variable length string which end in a char3, it's the char3 that we break on, other than that we keep receiving data.

Could anyone shed any light on our ProcessReceive code and see what could possibly be causing us issues and how we can solve this small issue (here's hoping it's a small issue!)

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
The dynamic Type in C# Simplifies COM Member Access from Visual FoxPro

I’ve written quite a bit about Visual FoxPro interoperating with .NET in the past both for ASP.NET interacting with Visual FoxPro COM objects as well as Visual FoxPro calling into .NET code via COM Interop. COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot… >>> More
