DO Chat Example

I am working on a chat program that I could use to explain and demonstrate Distributed Objects (cause I think they are really cool). I have two applications, the server, which is intended to not be seen by the students, and the client, which is intended to be built by the students. It works so far

Inconsistent Socket Communications

I am trying to set up a client-server chat application for practice. I am getting inconsistent communications. Meaning that it works some of time and doesn't work some of the time during the same application run. Any help will be greatly appreciated Here are the projects: www.justingiboney.com/co

Re: DO Chat Example

inconsistent nature of the program: I start up the server on one machine. I also set up a client on that machine and another one. During the process of sending messages back and forth. Some get sent, and others do not. Thanks > On Jul 26, 2008, at 3:38 AM, Justin Giboney wrote: >> It works so fa

Re: Subclassing NSArrayController?

This is maybe an answer as well as a question. Doesn't the bindings call the init method when creating a class object? Couldn't you just overwrite the init method on your custom class to set any necessary values? Justin Giboney On Aug 19, 2008, at 8:27 AM, Chris Poliquin wrote

Re: Simple NSView Question

Thanks for the help. For some reason I pulled a custom view onto the screen and also pulled an object over to the file (instantiating an object). I connected the outlet to that instead of the view in the window. I don't know what I was thinking. Works well now. Thanks Justin Gibone

Re: Vended Object Setters

Actually that didn't work... it appears to be setting it as I go through the set method, but when I go to get it it is almost as if it is calling an object in a different memory set. I set up the protocol, and I am using bycopy. Thanks, Justin Giboney On Apr 17, 2008, at 9:25 AM

Re: GUI Time Field

Thank you for response, I hope I have improved my code. I am binding my text field to the variable "theDateTime." I know this works because if I uncomment the commented line, I can see the date and time. The problem is that the UI isn't updating. Thanks again. Justin Gi
