• Globally overrride MonthNames for all instances of a specific culture

  - by Pauli Østerø

  So, i have this problem where Microsoft actually got the month names wrong for the Greenlandic culture (kl-GL). I also know that i can pass my own array of string to the DateTimeFormatInfo.MonthNames Property, but it seems like the values i specify is only used in the scope of that one CultureInfo instance. Is there a way to tell .Net that every time i have an instance of the kl-GL culture these specific monthnames should be used? I know that you can create user specific cultures, but i don't have access to some legacy code to actually change the code to use a my own userspecified culture.

• Obtaining kerning information

  - by chadb

  How can I obtain kerning information for GDI to then use in GetKerningPairs? The documentation states that The number of pairs in the lpkrnpair array. If the font has more than nNumPairs kerning pairs, the function returns an error. However, I do not know how many pairs to pass in, and I don't see a way to query for it. EDIT I tried to do the following, however, it still gave me 0. Font* myFont = new Font(L"Times New Roman", 10); Bitmap* bitmap = new Bitmap(256, 256, PixelFormat32bppARGB); Graphics* g = new Graphics(bitmap); SelectObject(g->GetHDC(), myFont); //DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), -1, NULL ); DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), INT_MAX, NULL );

• How to make sure the value is reset in foreach loop in PHP

  - by kwokwai

  Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?

• file_get_contents() removing tab and new line characters

  - by Patrick Murray

  I am having an issue today with the file_get_contents() function. When reading large files, the newline and tab characters are often removed. Here is a minified example of how I am using this. I hope I am not the only one who has encountered this issue! :O Thank you for your time! <?php $file_name = "template.html"; $data = array( 'title' => 'Hello, World!', 'content'=> 'Hey stackoverflow!'); $file_contents = file_get_contents($file_name); foreach($data as $comment_name => $replacement_value){ $search = "<!-- ".strtoupper($comment_name)." -->"; $file_contents = str_replace($search, $replacement_value, $file_contents); } echo $file_contents; ?>

• Reference variable to an object instantiated/initialized in another class in Java

  - by Alex

  The reason I'm asking is because I'm getting NullPointerException. I now this is very easy but I'm pretty new programming and find this a bit confusing. So say I have initialized an object in a class and want to access that same object from another class. Like now for instance I'm working on a small Chess game, in my model Game class I have an instance of Board, an object. Board, in turn, has an array of Squares. Square[][]. Game has board, board has Square[][]. Now if I want to access the Square[][] through the object board (in Game) of type Board. Do I just declare a variable with the same name and type or do I have to initialize it again? Board board OR Board board = new Board(); Note, I have already initialized board in the class Game so if I do it again, won't they be two totally different Board objects?

• Split string into sentences based on periods

  - by rookie

  Hi all, I have written this piece of code that splits a string and stores it in a string array:- String[] sSentence = sResult.split("[a-z]\.\s+"); However, I've added the [a-z] because I wanted to deal with some of the abbreviation problem. But then my result shows up as so:- Furthermore when Everett tried to instruct them in basic mathematics they proved unresponsiv I see that I loose the pattern specified in the split function. Its okay for me to loose the period, but loosing the last letter of the word disturbs its meaning. Could some one help me with this and in addition also could someone help me with dealing with abbreviations? Like because I split the string based on periods, I do not want to loose the abbreviations. Thanks in advance

• Hibernate - join un related objects

  - by CuriousMind

  I have a requirement, wherein I have to join two unrelated objects using Hibernate HQL. Here is the sample POJO class class Product{ int product_id; String name; String description; } and Class Item{ int item_id; String name; String description; int quantity; int product_id; //Note that there is no composed product object. } Now I want to perform a query like select * from Product p left outer join Item i on p.product_id = i.item_id I want a multidimensional array as an output of this query so that I can have separate instances of Product and Item, instead of one composed in another. Is there any way to do this in Hibernate?

• Examples of both beautiful and ugly java code?

  - by tputkonen

  I would like to demonstrate how difficult it is for a layman to identify high quality code from flawed code. I'm thinking of doing this with the help of two java methods. Both of the methods should look like they do the same, pretty simple thing. However one of them should have several kind of flaws, for example: iteration with array off by one error string concatenations causing lots of objects to be created (as opposed to StringBuffer in the "good" code, which looks more complicated) possibly null pointer exception (but it should not be trivial to spot) Those are just some examples, all kinds of other issues including bugs and performance related structures are highly appreciated. Methods should be around 10-20 lines of length, and the task they do should be something simple - preferably printing something in an iteration.

• Question about a dialog form and submit errors

  - by user248959

  Hi, I have the link below that executes the action message/new which shows a form inside a jqueryui modal dialog. <div id="myDialog"> </div> echo jq_link_to_remote('Enviar mensaje', array( 'url' => 'mensaje/new?receptor='.$miembro->getId().'&tipo=0&estado=0', 'update' => 'myDialog', 'complete' => "jQuery('#myDialog').dialog({ width:375, height:220, top:123, resizable:false, modal:true, autoOpen: false }); jQuery('#myDialog').dialog('open')" )); The point: if there are submit errors the form is not showed inside the dialog form but in a empty page (mensaje/create).. Any idea? Javi

• Xcode automatically converts the object to NSArray

  - by Farrukh Javeid

  I have been working on an app and during the development, I am facing a very strange problem. I have a NSMutableArray tempSortedArray, which is full of objects of Store types. All the objects are valid as I can see them in my GUI, the problem arises when I iterate through the array, at index 90, which can be generally anyone, the XCode converts the Store object to NSMutableArray object. Any idea, why this is happening. This is the code to check out what I am doing: NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"cashBack" ascending:NO]; NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor]; NSArray *sortedArray = [storesArray sortedArrayUsingDescriptors:sortDescriptors]; for (int i = 0; i < [tempSortedArray count]; i++) { Store *currentStore = [tempSortedArray objectAtIndex:i]; NSLog(@"store class: %@", [currentStore.class description]); if (currentStore.cashBackTypeString != (id)[NSNull null]) { //do whatever is required to do here }

  if running function returns server misconfiguration error function build_path($cid) { $result = array(); $DB = new MySQLTable; $DB->TblName = 'shop_categories'; $where['cat_id']['='] = $DB->CleanQuest($cid); $res = $DB->Select('cat_id,cat_name,cat_parent', $where); if($res !== 'false') { $pid = mysql_fetch_array($res); if($pid['cat_parent'] !== 0) { Echo $pid['cat_parent']; build_path($pid['cat_parent']); } else { Echo $pid['cat_id']; return true; } } return false; } I can't find an error here. Please help. Sorry for disturbing you all. The trouble was in comparison 'if($pid['cat_parent'] !== 0)': $pid['cat_parent'] was a string with int(0) Can i build this function to store full path without using GLOBALS and SESSION vars?

• Syncronizing indices of function pointer table to table contents

  - by Thomas Matthews

  In the embedded system I'm working on, we are using a table of function pointers to support proprietary Dynamic Libraries. We have a header file that uses named constants (#define) for the function pointer indices. These values are used in calculating the location in the table of the function's address. Example: *(export_table.c)* // Assume each function in the table has an associated declaration typedef void (*Function_Ptr)(void); Function_Ptr Export_Function_Table[] = { 0, Print, Read, Write, Process, }; Here is the header file: *export_table.h* #define ID_PRINT_FUNCTION 1 #define ID_READ_FUNCTION 2 #define ID_WRITE_FUNCTION 3 #define ID_PROCESS_FUNCTION 4 I'm looking for a scheme to define the named constants in terms of their location in the array so that when the order of the functions changes, the constants will also change. (Also, I would like the compiler or preprocessor to calculate the indices to avoid human mistakes like typeo's.)

• Using JS script for "raining images". Can't seem to hide pre-loaded image

• How to use templated classes as function arguments? (C++)

  - by Keand64

  I have a class declared along the lines of template<int a, int b> class C { public: array[a][b]; } and I want to use it as argument in a function like this: bool DoSomeTests(C &c1, C &c2); but when I compile, it tells me 'use of class template requires template argument list.' I tried template<int a, int b> bool DoSomeTests(C &c1, C &c2); but I get the same error. How can I fix this?

• Java 7 New Features

  - by John W.

  I have done some good reading on the new java.util.concurrent features being introduced with the java 7 release. For instance, Phaser, TransferQueue and the more exciting Fork Join Framework. I recently saw a power point made by Josh Bloch about even more features that are going to be introduced however that link has been lost. For example I remember one change is being able to build a Map the same way you can build an array for: Map myMap = {"1,Dog","2,Cat"}; and so forth (this may not be 100% correct but the idea is there) Does anyone know of a list or just can name some new things to look forward to? Note: I did see a question asked http://stackoverflow.com/questions/213958/new-features-in-java-7 however it was asked ~2 years ago and I am sure the list of updates are more concrete. Thanks!

• UITableViewCell height with 0 rows

  - by Typeoneerror

  I've got a moderately uncustomized UITableView in my application that presents an array of up to 6 peers for a networking game. When no peers are found the numberOfRowsInSection is 0, so when it loads up, there's no rows in the table: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 0; } Trouble is, the height of each cell is not adjusted to match heightForRowAtIndexPath unless the numberOfRowsInSection is 0. I hard-coded in "1" for this and the height is adjusted. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return kTableRowHeight; } Can anyone tell me why this is? Will once the data that is being presented is longer than "0" length, will the height of the table cells jump to the correct height? I'd like them to be the correct height even if the row length is 0.

• Creating attribute sets and attributes programatically magento

  I am using the code listed on the following link =: http://www.magentocommerce.com/wiki/5_-_modules_and_development/catalog/programmatically_adding_attributes_and_attribute_sets Everything works until the point: // Just add a default group. else { $this->logInfo("Creating default group [{$this->groupName}] for set."); $modelGroup = Mage::getModel('eav/entity_attribute_group'); $modelGroup->setAttributeGroupName($this->groupName); $modelGroup->setAttributeSetId($id); // This is optional, and just a sorting index in the case of // multiple groups. // $modelGroup->setSortOrder(1); $model->setGroups(array($modelGroup)); } I am unsure where the object reference would need to be set from - I am attempting to have this as a separate file that can be automated - I am running this file by doing a require_once 'app/Mage.php'; Mage::app(); Any help in this would be greatly appreciated Thanks

• Which is more efficent PHP: array_intersect() OR array_intersect_key()

  - by Jordan Rutty

  Is it more efficient to use the key intersect or the value intersect if both key and value have the same contents for example: Array ( [743] => 743 [744] => 744 [745] => 745 [746] => 746 [747] => 747 [748] => 748 ) Is there any difference in performance in using one or the other with the same values. Similar to the difference of using double or single quotes?

• Get n Number of words using regex in Java

  - by Aymon Fournier

  I have a section of a book, complete with punctuation, line breaks etc. and I want to be able to extract the first n words from the text, and divide that into 5 parts. Regex mystifies me. This is what I am trying. I creates an array of index size 0, with all the input text: public static String getNumberWords2(String s, int nWords){ String[] m = s.split("([a-zA-Z_0-9]+\b.*?)", (nWords / 5)); return "Part One: \n" + m[1] + "\n\n" + "Part Two: \n" + m[2] + "\n\n" + "Part Three: \n" + m[3] + "\n\n" + "Part Four: \n" + m[4] + "\n\n" + "Part Five: \n" + m[5]; } Thanks!

• Detecting coincident subset of two coincident line segments

  - by Jared Updike

  This question is related to: How do I determine the intersection point of two lines in GDI+? (great explanation of algebra but no code) How do you detect where two line segments intersect? (accepted answer doesn't actually work) But note that an interesting sub-problem is completely glossed over in most solutions which just return null for the coincident case even though there are three sub-cases: coincident but do not overlap touching just points and coincident overlap/coincident line sub-segment For example we could design a C# function like this: public static PointF[] Intersection(PointF a1, PointF a2, PointF b1, PointF b2) where (a1,a2) is one line segment and (b1,b2) is another. This function would need to cover all the weird cases that most implementations or explanations gloss over. In order to account for the weirdness of coincident lines, the function could return an array of PointF's: zero result points (or null) if the lines are parallel or do not intersect (infinite lines intersect but line segments are disjoint, or lines are parallel) one result point (containing the intersection location) if they do intersect or if they are coincident at one point two result points (for the overlapping part of the line segments) if the two lines are coincident

• Stopping and Starting Apache Using PHP (!)

  - by Abs

  Hello all, I have two problems which are related. 1) I have a batch file that contains this: net stop wampapache net start wampapache Which tries to stop and start my wamp server. When I double click the stop.bat file with the above it works successfully. When I try to run that from my PHP script, it stops the server but doesn't start it fully which I am guessing is because Apache is waiting for that PHP process to exit? function php_kill(){ exec('stop.bat', $output = array(), $return); return $return; } 2) Is there a way to restart my webserver (apache) whilst keeping session variables that PHP needs available? Thanks all

• PHP Casting as Object type in foreach Loop

  Within the following code, $quiz_object->personalities contains an array of Personality() objects. // Loop through each personality that exists for the quiz foreach($quiz_object->personalities AS $existing_personality) { // Show all of the existing personalities echo $existing_personality->GetQuizMakerPersonalityHTML(); } How do I "cast" (I think that's the right word) my variable $existing_personality within the foreach loop as the object type? I wish to do this so that when I type $existing_personality->, I get the list of public functions available for that object type. At the moment, Zend doesn't know that it refers to a Personality object within the loop.
