Parse form values from HTTP POST

Does anyone know what the best way to parse form values from and HTTP Post is? I have a mini HTTP server in my app, and it needs to accept posts. I'm using CFHTTP to implement the server, so I have a CFHTTPMessageRef. I'm trying to figure out how to turn that into a dictionary of keys and

Re: MacBook Wake On Lan

Hi! If a MacBook does not go to sleep when it's closed, my guess is that it would probably overheat. I don't think that trying to override that behavior is a good idea at all, even if it is possible (which it may or may not be). As a side note, this is likely the wrong list for such a q

Animation curve is always linear though specified to be S-like

The problem is that my animation always seems to perform linearly, not S-like, although I specify it to do the latter. Here's my code: @interface MyAnimation : NSAnimation { } ... @end @implementation MyAnimation - (id)init { self = [super initWithDuration:0.1F animationCurve:NSAnimationEas

Re: passing an object between views

If I understand your question, it appears the concept you're missing is the Model-View-Controller (MVC) design pattern around which Cocoa is heavily designed. The controller should be where your XML (which belongs to the model layer) is generated. The controller would conceptually have an outlet

[Q] Using SFAuthorizationView in a Preference Pane project

How are you doing? I write a sample preference pane in which there are a few text fields and check boxes. They are organized as two groups: one for system-wide setting, and the other for a user-specific setting. I use the SFAuthorizationView for restricting users to access a system-wide sett

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 Giboney On Au
