• easy hex/float conversion

  - by yeus

  I am doing some input/output between a c++ and a python program (only floating point values) python has a nice feature of converting floating point values to hex-numbers and back as you can see in this link: http://docs.python.org/library/stdtypes.html#additional-methods-on-float Is there an easy way in C++ to to something similar? and convert the python output back to C++ double/float? This way I would not have the problem of rounding errors when exchanging data between the two processes... thx for the answers!

• What does wikipedia use for text and revision diffs

  I'm trying to take 2 versions of text (10 pages long) and compare the 2 to produce the difference. I know Wikipedia has a similar feature to compare revisions. Does anyone know what they use? I'm hoping they're using a php-driven solution.

• MySQL : Insert Exactly Same Data Multiple Rows Without PHP Loop

  - by Robert Hanson

So, I just need to insert some exactly same data and it's multiple rows (dynamic) but by using single INSERT syntax below : INSERT INTO outbox_multipart (TextDecoded) VALUES ('$SMSMessage') how to have this single INSERT syntax, but produce n number of rows?

• jQuery slideToggle - when div is toggled it pushes content out of viewable area (IE)

  - by Chris

  This is an annoying ocurrance in IE when I use the jQuery slideToggle effect. Without the div being open, page looks normal. The minute I toggle the div open, it extends past the current content, overtop of the footer, and out of the viewable browser area (Even after scrolling all the way down). This feature seems to work just fine in firefox. Do I need an additional hack or CSS to make it work in IE8?

• iOS - Open certain view controller with URL scheme

  - by hansenmd

  I'm playing around with URL schemes in my app. I easily made one to open my app, just adding the necessary items to info.plist. This current URL "myappname://" takes the user to the initial view controller, FirstTableViewController, but I was wondering if it would be possible to modify that URL scheme so it I can have one that takes the user to a certain view controller, such as ThirdTableViewController. I would use this as a handy feature in something like Launch Center.

  I was wondering if there's a way to check if an index exists before creating it or destroying it on MySQL. It appears that there was a feature request for this a few years back, but I can't find any documentation for a solution. This needs to be done in a PHP app using MDB2.

  Hi guys, I've got a TextBox in which user can input a their desired username. Underneath I've got a checkbox that once clicked it copies the user's email adress into the textfield and then disable it to prevent further changes. This feature is implemented by using jQuery. The problem is that I've got a RequiredFieldValidator on that TextBox and it looks like it can't validate a disabled textfield, even if the value is set. How can I solve this?
