• Is there a way to look up the Publishers URL using the linkshare.com API

  - by steve

  I'm able to retrieve the URL of a publisher only if their URL is in the title or the description using regular expression in linkshare's coupon API but in doing so, that leaves me with a lot of publishers not having a reference to their website which I need for the type of site that I am building. I was wondering if anyone else knows a way to reference the publishers URL preferably by their publisher ID or some other way?

• Converting upper-case string into title-case using Ruby

  - by wsb3383

  Hi, all. I'm trying to convert an all-uppercase string in Ruby into a lower case one, but with each word's first character being upper case. Example: convert "MY STRING HERE" to "My String Here". I know I can use the .downcase method, but that would make everything lower case ("my string here"). I'm scanning all lines in a file and doing this change, so is there a regular expression I can use through ruby to achieve this? Thanks!

  - by Jryl

  I'm working with Twitter Bootstrap and the regular navbar you see in the guides: http://twitter.github.io/bootstrap/components.html#navbar I don't want the navigation to stretch all the way left or right but stay where I can see both sides just like in the guide.

• Allow IExtenderProvider control to attach to controls on a UserControl

  - by Justin

  VB.NET 2.0 Framework I developed a control that implements IExtenderProvider in order to attach to controls and display a form for translating of the text of that control. This works great on regular controls on the form but the IExtenderProvider is not attaching to controls on UserControls, which makes sense. Is it possible to modify the UserControls or my IExtenderProvider control to enable it to attach to controls on a UserControl? Thanks!

• Building a decision-making game in jQuery? Where would I store data....

  - by redconservatory

  I built a slideshow/decision-making game in Flash but would like to try to redo it using jQuery. The slideshow part seems simple enough, however I have a series of user decisions that I'm not sure how to approach. In flash, if the user makes a decision, I would just store this in a variable or shared local objects, is this the same for jQuery? i.e. mix regular javascript variables with the jQuery?
