• Change color of disabled radiobutton list element

  - by Dave

  I've got a radiobuttonlist with a bunch of list items, some of them disabled. The label control beside the radio button turns gray, which can be hard to read. How do I change the color of the label? I've tried CSS, changing the forecolor - nothing seems to work: currentButton.Attributes.Add("class", "disabled"); Any ideas?

• Convert PPT to PNG via python

  - by uswaretech

  I want to convert PPT to png, or other image formats using Python. This question has been asked on SO, but essentially recommends running OpenOffice in headless X server, which was an absolute pain last time I used it. (Mostly due to hard to replicate bugs due to OO crashing.) Is there any other way, (Hopefully using Linux CLI utilities only, and pure Python above them?)

• Firefox add-on for examining z-indexes

  - by hekevintran

  I'm working on a fairly large site and am having trouble managing z-indexes. Is there a Firefox add-on that will look at a page and give me an ordered list of every element with a z-index declared? That would save a ton of times for the cases where a z-index was wrong or hard to find.

• What are some funny error pages websites have?

  - by Dean

  This question is along the same lines as What are some funny loading statements to keep my users amused, I want screenshots of all the coolest "error" pages site's throw up when something's broken. I know pandora.com talks about a panda ravaging it's way through the office, twitter's has the little birds floating around or something, sourceforge had one with some funny robots the other day. I'm sure I saw a blog once that had a bunch of them, but it's kinda hard to google "error pages". Community Wiki, of course :)

• Securing a .NET Application [closed]

  - by beakersoft

  Duplicate: Protecting .NET Code from Reverse Engineering We've recently released a small application and this weekend I found a cracked version of it on Piratebay that had the registration checking removed, so the app ran as if it was a registered version. Apart from using a code obfuscation tool (which doesn't seem to be that hard to get around), are there any standard things we should be doing to make our .NET applications more difficult to crack?

• Tic-Tac-Toe AI: How to Make the Tree?

  - by cam

  I'm having a huge block trying to understand "trees" while making a Tic-Tac-Toe bot. I understand the concept, but I can't figure out to implement them. Can someone show me an example of how a tree should be generated for such a case? Or a good tutorial on generating trees? I guess the hard part is generating partial trees. I know how to implement generating a whole tree, but not parts of it.

• How to convert a string into a Point?

  - by NateD

  I have a list of strings of the format "x,y". I would like to make them all into Points. The best Point constructor I can find takes two ints. What is the best way in C# to turn "14,42" into new Point(14,42);? I know the Regex for doing that is /(\d+),(\d+)/, but I'm having a hard time turning those two match groups into ints in C#.

• How to output LogCat to Console?

  - by Shooshpanchick

  Is there a way to make LogCat's output to appear in Console view in Eclipse? LogCat view is much less convenient that Console, because it's hard to see long messages in it (they are trimmed by column border) and there are no clickable highlighting in exception stack traces to quickly navigate to source of error.

• How to define multiple CSS attributes in JQuery?

  - by Edward Tanguay

  Is there any syntactical way in JQuery to define multiple CSS attributes without stringing everything out to the right like this: $("#message").css("width", "550px").css("height", "300px").css("font-size", "8pt"); If you have, say, 20 of these your code will become hard to read, any solutions?

• Is it worth purchasing Mahout in Action to get up to speed with Mahout, or are there other better sources?

  - by gab

  I'm currently a very casual user of Apache Mahout, and I'm considering purchasing the book Mahout in Action. Unfortunately, I'm having a really hard time getting an idea of how worth it this book is -- and seeing as it's a Manning Early Access Program book (and therefore only currently available as a beta-version e-book), I can't take a look myself in a bookstore. Can anyone recommend this as a good (or less good) guide to getting up to speed with Mahout, and/or other sources that can supplement the Mahout website?

• ruby socket dgram example

  - by Bub Bradlee

  I'm trying to use unix sockets and SOCK_DGRAM in ruby, but am having a really hard time figuring out how to do it. So far, I've been trying things like this: sock_path = 'test.socket' s1 = Socket.new(Socket::AF_UNIX, Socket::SOCK_DGRAM, 0) s1.bind(Socket.pack_sockaddr_un(sock_path)) s2 = Socket.new(Socket::AF_UNIX, Socket::SOCK_DGRAM, 0) s2.bind(Socket.pack_sockaddr_un(sock_path)) s1.send("HELLO") s2.recv(5) # should equal "HELLO" Does anybody have experience with this?

So %ProgramFiles%\Internet Explorer\hmmapi.dll becomes C:\Program Files\Internet Explorer\hmmapi.dll I like to know if there is an API call that can do this, or do I have to do this the hard way and detect %..% sequences and replace them with the appropriate environment variable?

• Pretty-printing of numpy.array

  - by camillio

  Hello, I'm curious, whether there is any way to print formated numpy.arrays, e.g., in the way similar to this: x = 1.23456 print '%.3f' % x If I want to print the numpy.array of floats, it prints several decimals, often in 'scientific' format, which is rather hard to read even for low-dimensional arrays. However, numpy.array apparently has to be printed as a string, i.e., with %s. Is there any solution ready for this purpose? Many thanks in advance :-)

• Word 2007, Open XML - embedding an image

  - by agnieszka

  Do you know what basic information MUST include a paragraph (w:p) in document.xml inside a *.docx document, that specifies an image? I do know there must be <a:blip r:embed="rId4" /> specifing the relation id, but what else? It's very hard to find it in google and experimenting with cutting out tags from a ready document or reading the specification takes a lot of time. An example with all the required tags would be greatly appreciated.
