• Why ObservableCollection is not updated on items change?

  - by PaN1C_Showt1Me

  I noticed that ObservableCollection in WPF reflects changes in GUI only by adding or removing an item in the list, but not by editing it. That means that I have to write my custom class MyObservableCollection instead. What is the reason for this behaviour? Thanks

• How do I arbitrarily distort a textured polygon?

  - by Archagon

  I'd like to write a program that lets me arbitrarily distort a textured polygon by dragging its vertices. I want the texture to distort fluidly and without overlap, assuming the new polygon doesn't intersect itself. I should also be able to repeat the process with the new shape, and with a minimum amount of loss. Are there any algorithms for doing this?

  - by Inferis

  Title says it all. I'm trying to write an extension for VS2010, but I get this every time: Hit F5 to start debugging A new instance of visual studio starts up I can see a bunch of DLLs loading in the debug host while the new instance is starting It then fails with a "LoaderLock". When I continue after that, the new instance is fully functional, but there's no debugging happening at all. The same happens when creating an addin. Any clues?

• Is there any way to send a mail from within my iPhone application?

  - by Mustafa

  I want to send an email from within my iPhone application, primarily because i don't want to quit my application. Is there ANY way to do that? Solution: 1) I found this open source API which does that: http://code.google.com/p/skpsmtpmessage/ Anyone can write their own smtp client for this purpose. (If you can invest that much time - that is) 2) Use a web service to send the message details and handle message sending functionality at server end. Thanks.

• convert string to argv in c++

  - by aaronstacy

  I have an std::string containing a command to be executed with execv, what is the best "C++" way to convert it to the "char *argv[]" that is required by the second parameter of execv()? To clarify: std::string cmd = "mycommand arg1 arg2"; char *cmd_argv[]; StrToArgv(cmd, cmd_argv); // how do I write this function? execv(cmd_argv[0], cmd_argv);

• Listing defined functions in bash

  - by Charles Duffy

  I'm trying to write some code in bash which uses introspection to select the appropriate function to call. Determining the candidates requires knowing which functions are defined. It's easy to list defined variables in bash using only parameter expansion: $ prefix_foo="one" $ prefix_bar="two" $ echo "${!prefix_*}" prefix_bar prefix_foo However, doing this for functions appears to require filtering the output of set -- a much more haphazard approach. Is there a Right Way?

• Creating a byte array from a stream

  - by Bob

  What is the preffered method for creating a byte array from an input stream? Here is my current solution with .NET 3.5. Is it still a better idea to read and write chunks of the stream? Stream s; byte[] b; using (BinaryReader br = new BinaryReader(s)) { b = br.ReadBytes(s.Length); }

• jquery multiple ajax check for all done? (order not important)

  - by second

  Is there a neat way to make sure a bunch of ajax callbacks have all finished? They don't need to be executed in order, i just need all the data to be there. one idea is to have them all increment a counter on completion and check if counter == countMax, but that seems ugly. Also, are there sync issues? (from simultaneous read/write to the counter)

• How can I determine a file extension given a file path in LaTeX?

  - by Frank

  I am attempting to write a LaTeX package which leverages the minted package's \inputminted command. My \mycommand command takes two parameters, the first being a path to a file, and I want to pass the file's extension to the \inputminted command: \newcommand\mycommand[2]{ \inputminted{#1}{...} } Note that the above won't work since the full path is passed to \inputminted. Example: \mycommand{/path/to/Test.java}{blah} should invoke \inputminted{java}{...}

  Would you write something like: enum XYZ_TYPE {X=1, Y=2, Z=3}; I saw it and the suffix _TYPE confuses me in the enum context. There is a strong prospect that it is because I am not bright.

• C++ enum in foreach

  - by Spencer

  I've have a card class for a blackjack game with the following enums: enum Rank { Ace, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King }; enum Suit { Clubs, Diamonds, Hearts, Spades }; When I create the deck I want to write the code like this: // foreach Suit in Card::Suit // foreach Rank in Card::Rank // add new card(rank, suit) to deck I believe there is no foreach in c++. However, how do I traverse an enum? Thanks, Spencer
