• Printing values of all fields in C++ structure

  - by Zhinkaas

  Say a simple structure struct abc { int a; char b; } I got some value in a variable defined as its structure and now I want to print below a = [some value] b = [some character] What is the best way to achieve this for an arbitrary structure without having to write a dump...(...) function for each of the structure I encounter?

• How can I retrieve all the returned variables from a function?

  - by user1447941

  import random def some_function(): example = random.randint(0, 1) if example == 1: other_example = 2 else: return False return example, other_example With this example, there is a chance that either one or two variables will be returned. Usually, for one variable I'd use var = some_function() while for two, var, var2 = some_function(). How can I tell how many variables are being returned by the function?

• How can I ensure that nested transactions are committed independently of each other?

  - by Caldera

  If I have a stored procedure that executes another stored procedure several times with different arguments, is it possible to have each of these calls commit independently of the others? In other words, if the first two executions of the nested procedure succeed, but the third one fails, is it possible to preserve the results of the first two executions (and not roll them back)? I have a stored procedure defined something like this in SQL Server 2000: CREATE PROCEDURE toplevel_proc .. AS BEGIN ... while @row_count <= @max_rows begin select @parameter ... where rownum = @row_count exec nested_proc @parameter select @row_count = @row_count + 1 end END

• Answered: Selecting even table rows from a table element

  - by mvrak

  The issue I am having is: How do I go from a variable pointing at an element to using CSS selectors? I want to make this work: function highlight(table) {$(table " > :even").toggleClass('highlight');} where table is a reference to a table element. I don't want answers that tell me to use $('#table') because that defeats the point of the generality I am trying to make. Thanks

• Weird constants

  - by Quassnoi

  I've seen these in real code: #define SCREEN_DIMENSIONS 2 #define THREE_THOUSAND_FIVE_HUNDRED_TWENTY_TWO 3522 What is the weirdest constant you've ever seen? P. S. And of course my favorite in JScript: bool b; switch (b.ToString().length) { case 4: // true ... break; case 5: // false ... break; )

• Just seen a factory style object creating in JavaScript (without literals). What else do I need to k

  - by alex

  I have just seen this in code var thisYear = (new Date()).getFullYear(); See it live on JSbin. This is cool, as I've always done something like that in 2 lines, i.e. create the new object instance and assigned it to a variable, then called the method on it. Is this new method fine to use everywhere? Any gotchas?

  - by Brian Roisentul

  I'm working with ruby on rails 2.3.4 and I yesterday I found out I cannot send emails any more.

• Extract dates from filename(C#3.0)

  - by Newbie

  I have a situation where I need to extract dates from the file names whose general pattern is [filename_]YYYYMMDD[.fileExtension] e.g. "xxx_20100326.xls" or x2v_20100326.csv The below program does the work //Number of charecter in the substring is set to 8 //since the length of YYYYMMDD is 8 public static string ExtractDatesFromFileNames(string fileName) { return fileName.Substring(fileName.IndexOf("_") + 1, 8); } Is there any better option of achieving the same? I am basically looking for standard practice. I am using C#3.0 and dotnet framework 3.5 Thanks

• Push SVG String into Dom?

  - by Colin

• Matlab - building an array while looping

  - by Mark

  Hello, I have a for loop that loops over one array... for i=1:length(myArray) In this loop, I want to do check on the value of myArray and add it to another array myArray2 if it meets certain conditions. I looked through the Matlab docs, but couldn't find anything on creating arrays without declaring all their values on initialization or reading data into them in one shot. Many thanks!

• C#: How to find the default value for a run-time Type?

  - by George Mauer

  So given a static type in your code you can do var defaultMyTypeVal = default(MyType); How would you do the same thing given a variable of Type so you can use it during runtime? In other words how do I implement the following method without a bunch of if statements or using Generics (because I will not know the type I'm passing into the method at compile time)? public object GetDefaultValueForType(Type type) { .... }

• 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?

• How do I convert a number (as a String) to an array of bytes in Java?

  - by user1795595

  I'm creating a method specific method for a java project i'm working on. The UML given specifies the return type to be of static byte[] that accepts the arguments (String, byte) So far, looks like this: public static byte[] convertNumToDigitArray(String number, byte numDigits) { } This method is supposed to convert a number (as a String) to an array of bytes. The ordering must go from most to least significant digits. For example, if the number String is “732” then index 0 of the array should contain 7. The last argument (numDigits) should match the length of the string passed in. How do I do this?

• How to pass a file (read from Java) most effectively to a native method?

  - by soc

  Hi, I have approx. 30000 files (1MB each) which I want to put into a native method, which requires just an byte array and the size of it as arguments. I looked through some examples and benchmarks (like http://nadeausoftware.com/articles/2008/02/java_tip_how_read_files_quickly) but all of them do some other fancy things. Basically I don't care about the contents of the file, I don't want to access something in that file or the byte array or do anything else with it. I just want to put a file into a native method which accepts an byte array as fast as possible. At the moment I'm using RandomAccessFile, but that's horribly slow (10MB/s). Is there anything like byte[] readTheWholeFile(File file){ ... } which I could put into native void fancyCMethod(readTheWholeFile(myFile), myFile.length()) What would you suggest?

• Source Code Browser

  - by James Fielding

  Hello I'm looking for a piece of relatively simple software to browse large C++ project. What I would like is something that is somewhere between a simple text editor and a full-blown IDE like Eclipse. I would like syntax highlighting, a way to see all classes/methods defined in a file, a way to find where a particular method is called from and where a variable is declared/defined. Any ideas? Thank you!

• Prevent Excel from evaluating unneeded expressions in OR()

  - by Wesley

  IF(OR(ISNA(MATCH(8,B10:B17,0)),MATCH(8,B10:B17,0)>8),"",...BLAH...) I understand how to fix this problem by rearranging my formula. I have it the way it is to show this point. You can see the OR() statement checks to see if the first MATCH() returns NA. When it does, OR() should automatically return TRUE and not evaluate the second MATCH() because conditions have been met for the OR() to return true no matter what other arguments there are. You'll notice that the first and second MATCH() functions do the same thing. What's happening is the entire function is returning NA because the second MATCH() is executing even though it doesn't have to, the OR() has been satisfied with one TRUE, therefore the function should return "". Is this a bug or is this intentional?

  I am curious to know if there is a way to edit code in VS 2008 right when it has hit a breakpoint and I am walking thru the code... can I modify the code (such as the value in a variable or if my stepthrough line is about to hit an if statement ... can I modify the if statement....etc)? So far, I have to stop running VS, modify the code, then hit F5 and wait till the breakpoint is hit again.
