When new fields are added to a dialog by engineers on a team, the new widgets can often not be inserted in tab correct order.

• What's your favorite cross domain cookie sharing approach?

  - by Haoest

  I see iframe/p3p trick is the most popular one around, but I personally don't like it because javascript + hidden fields + frame really make it look like a hack job. I've also come across a master-slave approach using web service to communicate (http://www.15seconds.com/issue/971108.htm) and it seems better because it's transparent to the user and it's robust against different browsers. Is there any better approaches, and what are the pros and cons of each?

• What will be the setup process for website development?

  - by Vijay Shanker

  Hi, I want to create a simple site for my personal usage. And this only in python based technologies. So I want to get a expert oponian on this topic. What should i used as platform? I did a search for available options and found Django, grok, web2py and many more of these. Which one a novice use should use? If I choose to use only the basic python scripts then what option i have to work on? http://wiki.python.org/moin/WebBrowserProgramming. This link on python site confused me more, instead of solving my curiosity about the topic. Please give some pointer to accurate and easy to understand reading materials. I have got a idea of developing java based web applications using either spring-webmvc and struts. Can I relate Java process to python process for web development?

• How to seperate the model from the view?

  - by geejay

  I have a bunch of model objects. These objects end up being rendered as views (say forms) in a rich client app. I started to annotate the fields in the model objects (Java annotations) with things that let me render them as forms on the fly (e.g displayname, group, page, validvalues). I now realise that the view has crept into the model. How should I seperate the view logic out of the model objects? TECH: Java, Java Annotations, Eclipse RCP

• What is the best way to do Bit Field manipulation in Python?

  - by ZebZiggle

  I'm reading some MPEG Transport Stream protocol over UDP and it has some funky bitfields in it (length 13 for example). I'm using the "struct" library to do the broad unpacking, but is there a simple way to say "Grab the next 13 bits" rather than have to hand-tweak the bit manipulation? I'd like something like the way C does bit fields (without having to revert to C). Suggestions?

• Fastest way to store/retrieve a dictionary - SQL, text file...?

  - by AP257

  Hi all, This is a really really super dumb question, so I apologise, but I'd be grateful for some advice. I've got a text file of words and word frequencies. It's very large - theoretically we're talking millions of rows. I just want to retrieve values from the file, and do it as quickly and efficiently as possible (for a web app, in Django). My question is: what is the best way to store and retrieve the values? Should import them into SQL? Or keep the file and use grep? Or put them into a JSON dictionary...? Or some other way? Sorry for the dumb question, would be very grateful for advice!

• What's the simplest way to make a scrollable list of controls with labels?

  - by Jon Cage

  Using C++/CLI and Windows Forms, I'm trying to make a simple scrollable list of labelled text controls as a way of displaying some data fields. I'm having trouble making a TableLayoutPanel scrollable - every combination of properties I've tried seems to result in some really peculiar side effects. So I have two questions: Is this the best way to do it. If it is a reasonable approach, what magic combination of settings should I apply to the table layout panel to make it play ball?
