• When parsing XML with jquery, how can we pass the current node from within each() to another functio

  - by Johusa

  Say we have an XML document with many book nodes... When parsing XML with jquery, how can i pass the current node from each() iteration to another function that will do some stuff until something is reached and then go back to the previous function (passing along the current node from this function back to the first function)? Here something more descriptive (this is just an example out of my head, not accurate): function MyParser(x1,x2,dom) { // if i am called by anotherFunction(thisNode) proceed from the passed node dom.find('book').each(function() { var Letter = thisNode.find(author).charAt(0); if(x1 == Letter) { // print everything till the next letter (x2) anotherFunction(thisNode) } } } function anotherFunction(x2,thisNode) { //continue parsing here until you reached x2 //when x2 is reached, return to previous function passing again the current node }

• Need help with a sub query/group/order (get latest comment for each ordered topic)

  - by Scarface

  Hey guys I have a query that currently finds the latest comment for each of a user's topics and then orders topics by that comment's timestamp. What I want to do is expand on this query's use and print the latest comment for each topic. The problem with this query is that while it orders the topics correctly, it prints seemingly random comments for each topic. I am trying to implement a sub query but I am not quite sure how to approach it. I was thinking that I just had to somehow use this query to get the comments. If anyone has any ideas I would really appreciate it. Here is what I think I need to add SELECT * FROM comments where topic_id='$topic_id' ORDER BY timestamp DESC LIMIT 1 Here is the query I need to modify SELECT topic.topic_title, topic.content_type, topic.subject_id, topic.creator, topic.description, topic.topic_id,comments.message,comments.user FROM comments JOIN topic ON topic.topic_id = comments.topic_id WHERE topic.creator = '$user' AND comments.timestamp > $week GROUP BY topic_id ORDER BY MAX(comments.timestamp) DESC

• c++ Mixing printf, cout with wprintf, wcout

  - by Bo Jensen

  I know you should not mix printing with printf,cout and wprintf,wcout, but have a hard time finding a good answer why and if it is possible to get round it. The problem is I use a external library that prints with printf and my own uses wcout. If I do a simple example it works fine, but from my full application it simply does not print the printf statements. If this is really a limitation, then there would be many libraries out there which can not work together with wide printing applications. Any insight on this is more than welcome.

• Problem with CFNetRegister

  - by xtrahotsauce

  I'm trying to work with CFNetServices by trying to start up and publish a service asynchronously. I'm trying to use the example code from here: http://developer.apple.com/mac/library/documentation/Networking/Conceptual/NSNetServiceProgGuide/Articles/CFNetServices.html#//apple_ref/doc/uid/30001276-SW3, but CFNetRegisterWithOptions always fails. (CFNetRegister is deprecated now). When I print out the error struct, it looks like this: (gdb) p error $1 = { domain = 10, error = -72004 } Which doesn't seem correct to me. Does anyone know what might be wrong? Thanks!

• Python 3.1: Syntax Error for Everything! (Mac OS X)

  - by Nathan G.

  I updated to Python 3.1.3 (I've got OS X 10.6). If I type python in Terminal, I get a working 2.6.1 environment. If I type python3 in Terminal, I get a 3.1.3 environment. Everything looks fine until I do something. If I try to run print "hello", I get a syntax error. This problem is the same in IDLE. I tried deleting everything for 3.1 and then reinstalling, but it hasn't worked. Ideas? Thanks in advance!

• Number 0 is not saving to database as a prefix in SQL Server of CHAR data type column

  - by gmhk

  I am trying to insert an value as '019393' into a table with a CHAR(10) column. It is inserting only '19393' into the database I am implementing this feature in a stored procedure, doing some manipulation like incrementing that number by 15 and saving it back with '0' as the prefix I am using SQL Server database Note: I tried CASTING that value as VARCHAR before saving to the database, but even that did not get the solution Code SELECT @fromBSB = fromBSB, @toBSB = toBSB, @type = Type FROM [dbo].[tbl_REF_SpecialBSBRanges] WHERE CAST(@inputFromBSB AS INT) BETWEEN fromBSB AND toBSB SET @RETURNVALUE = @fromBSB IF(@fromBSB = @inputFromBSB) BEGIN PRINT 'Starting Number is Equal'; DELETE FROM tbl_REF_SpecialBSBRanges WHERE Type = @type AND fromBSB = @fromBSB AND toBSB = @toBSB INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@type, CAST('0' + @fromBSB + 1 AS CHAR), @toBSB) INSERT INTO [tbl_REF_SpecialBSBRanges] ([Type], [fromBSB], [toBSB]) VALUES(@inputBSBName, @inputFromBSB, @inputToBSB) END

• Will Sytem.currentTimeMillis always return a value >= previous calls?

  - by 1984isnotamanual

  http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#currentTimeMillis() says: Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds. It is not clear to me if I am guaranteed that this code will always print ever increasing (or the same) numbers. while (1) { System.out.println(System.currentTimeMillis() ); }

• PHP from database and query

  - by Kyle R

  I have a table: id, affiliate Each time somebody clicks a link, a new row is inserted, ID being the ID of the page, and affiliate being the ID of the affiliate. For example: Page ID: 9 Affiliate ID: 1 Page ID: 9 Affiliate ID: 2 Page ID: 9 Affiliate ID: 3 I only have 3 affiliates. I want to select this information, and group them by affiliate, for the ID. I have tried this query: SELECT COUNT(*) FROM table WHERE id = '9' GROUP BY affiliate It works fine when I do it in php my admin, how do I get the info in PHP? I have tried: $q = mysql_query("SELECT COUNT(*) FROM table WHERE id = '" . $id . "' GROUP BY affiliate"); $r = mysql_fetch_array($q); When trying to print the data onto the page, I am only getting one result. Do I need to use a foreach/while loop to get all 3? How would I go about doing this? Thank you!

• Getting all matches for a regexp on clojure

  - by Deleteman

  I'm trying to parse an HTML file and get all href's inside it. So far, the code I'm using is: (map #(println (str "Match: " %)) (re-find #"(?sm)href=\"([a-zA-Z.:/]+)\"" str_response)) str_response being the string with the HTML code inside it. According to my basic understanding of Clojure, that code should print a list of matches, but so far, no luck. It doens't crash, but it doens't match anything either. I've tried using re-seq instead of re-find, but with no luck. Any help? Thanks!

• C++ Declaring an uninitialized variable without a null constructor

  - by xbonez

  Consider the DUPoint class, whose declaration appears below. Assume this code appears in a file named DUPoint.h: #include <string> class DUPoint { public: DUPoint (int x, int y); int getX () const; int getY () const; void setX (int x); void setY (int y); void print(); private: int x_; int y_; }; Is it true that you cannot declare an uninitialized DUPoint variable with a statement such as DUPoint P; using this class as currently configured because it has no null constructor?

• doubt in - Function Objects - c++

  - by Eternal Learner

  I have a class class fobj{ public: fobj(int i):id(i) {} void operator()() { std::cout<<"Prints"<<std::endl; } private: int id; }; template<typename T> void func(T type) { type(); } My Doubt is if I invoke func like Method 1: func(fobj(1); the message I wanted to print is printed. I was always thinking I needed to do something like Method 2: fobj Iobj(1); // create an instance of the fobj class func(Iobj); //call func by passing Iobj(which is a function object) How does Method 1 work? I mean what exactly happens? and how is a call made to the operator() in class fobj ?

• A server-side language to Learn

  - by Roth

  I'm a graphic designer, with experience in print design. In fact, I'm working on digital prepress since 4 years ago. I'm doing a course on web design right now, although I have been studying it on my own for a while, online. So, my question is, what kind of server-side language do I need to learn? I'm feel comfortable with HTML, CSS, and Javascript, even with preprocessors like SASS and LESS, but server-side scripting becomes a nightmare to me. So, what kind of language is necessary to learn? Any book or resource to that specific language? Thanks a lot for your answers.

• Java/Swing: JTable.rowAtPoint doesn't work correctly for points outside the table?

  - by Jason S

  I have this code to get a row from a JTable that is generated by a DragEvent for a DropTarget in some component C which may or may not be the JTable: public int getRowFromDragEvent(DropTargetDragEvent event) { Point p = event.getLocation(); if (event.getSource() != this.table) { SwingUtilities.convertPointToScreen(p, event.getDropTargetContext().getComponent()); SwingUtilities.convertPointFromScreen(p, this.table); if (!this.table.contains(p)) { System.out.println("outside table, would be row "+this.table.rowAtPoint(p)); } } return this.table.rowAtPoint(p); } The System.out.println is just a hack right now. What I'm wondering, is why the System.out.println doesn't always print "row -1". When the table is empty it does, but if I drag something onto the table's header row, I get the println with "row 0". This seems like a bug... or am I not understanding how rowAtPoint() works?

• Partially fattening a list

  - by alj

  This is probably a really silly question but, given the example code at the bottom, how would I get a single list that retain the tuples? (I've looked at the itertools but it flattens everything) What I currently get is: ('id', 20, 'integer') ('companyname', 50, 'text') [('focus', 30, 'text'), ('fiesta', 30, 'text'), ('mondeo', 30, 'text'), ('puma', 30, 'text')] ('contact', 50, 'text') ('email', 50, 'text') what I would like is a single level list like: ('id', 20, 'integer') ('companyname', 50, 'text') ('focus', 30, 'text') ('fiesta', 30, 'text') ('mondeo', 30, 'text') ('puma', 30, 'text') ('contact', 50, 'text') ('email', 50, 'text') def getproducts(): temp_list=[] product_list=['focus','fiesta','mondeo','puma'] #usually this would come from a db for p in product_list: temp_list.append((p,30,'text')) return temp_list def createlist(): column_title_list = ( ("id",20,"integer"), ("companyname",50,"text"), getproducts(), ("contact",50,"text"), ("email",50,"text"), ) return column_title_list for item in createlist(): print item Thanks ALJ

• python's `with` statement

  - by Prestel Nué

  Hi there, seems like I do not understand something with---the python with statement. Consider this class: class test(object): def __enter__(self): pass def __exit__(self, *ignored): pass now, when using it with with, like in with test() as michael: print repr(michael) I would expect some output like <test instance at memore blah>. But I get None. Something wrong here? Any suggestions would help. (I am using Python 2.6.6.) EDIT: Thanks to ephement for pointing me to the documentation. The __enter__ method should read def __enter__(self): return self

• Why the streams in C++?

  - by oh boy

  As you all know there are libraries using streams such as iostream and fstream. My question is: Why streams? Why didn't they stick with functions similar to print, fgets and so on (for example)? They require their own operators << and >> but all they do could be implemented in simple functions like above, also the function printf("Hello World!"); is a lot more readable and logical to me than cout << "Hello World"; I also think that all of those string abstractions in C++ all compile down to (less efficient) standard function calls in binary.

• What does this java output mean?!

  - by Phil

  public class Arrys { private int[] nums; //Step 3 public Arrys (int arrySize) { nums = new int[arrySize]; } public int [] getNums (){ return nums; } } Test class: public class TestArrys { public static void main(String args[]) { //Step 4 Arrys arry = new Arrys(10); System.out.println("\nStep4 "); for(int index = 0; index < arry.getNums().length; index++) { System.out.print(arry.getNums()); } } } It's incredibly simple, that is why I think I'm doing something fundamentally wrong. All I want is to display the value of the array. This is what I get back. I am totally lost, there is nothing in my book that explains this nor does googling it help.
