• How to call a function from another function in c++?

  - by karikari

  I have this function definition inside my cpp file; LRESULT CRebarHandler::onSetRedraw(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled) { bHandled=false; if (m_ieVer==6){ if (!m_hWndToolbar) scanForToolbarSlow(); } return S_OK; } My problem is I don't know how to call it from another function inside the same file. I want to call it from this function: void CRebarHandler::setButtonMenu2(){ bool b=false; onSetRedraw(0,0,0,false); <------ is this the correct way? } Must I provide all the 4 values? Can I just send no value? Help me..

• javascript regular expressions

  - by Zhasulan Berdybekov

  Help me with regular expressions. I need to check the text on the hour and minute. That is the first case, the text can be from 0 to 12. In the second case, the text can be from 1 to 60. this is my code: var hourRegEx = /^([0-9]{2})$/; //You can fix this line of code? $(document).ready( function(){ $('form.form').submit(function(){ if( $('input.hour').val().match(hourRegEx) ){ return true; } return false; }); }); In my case, the code says that, for example 52, too, the correct answer

• access a property via string with array in php?

  - by sprugman

  (This is in drupal, but I don't really think that matters.) I have a big list of properties that I need to map between two objects, and in one, the value that I need to map is buried inside an array. I'm hoping to avoid hard-coding the property names in the code. If I have a class like this: class Product { public $colors, $sizes; } I can access the properties like this: $props = array('colors', 'sizes'); foreach ($props as $p) { $this->$p = $other_object->$p; } As far as I can tell, if each of the properties on the left are an array, I can't do this: foreach ($props as $p) { $this->$p[0]['value'] = $other_object->$p; } Is that correct, or am I missing some clever way around this?

• Django model data consistency

  - by Mark

  When creating a form, you can define a bunch of methods, clean_xyz, to make sure the data gets forced into the correct format. Is there any way to do this on a model level? Perhaps I can override the field setters somehow? I want it so that if I write something like my_address.postal_code = 'a1b2c3' It will automatically get formatted into A1B 2C3. Perhaps throw an exception if it can't be converted. That way I know I'll never have any malformed data in the database.

• CSS and JQuery: spaces inside image name break code of url()

  - by Shyam

  Hi, I have a page that is supposed to display a larger version of an image when hovered over a thumbnail. I have a 'div' with an ID and the JQuery code is as following: $(document).ready(function(){ $('img').hover(function() { var src = $("#im" + this.id).attr("src"); $('#viewlarge').css('backgroundImage','url(' + src +')'); return false; }); }); The images I use, are generated by a Ruby script that "generate" an image with a similar, yet different id. However, sometimes, photo's are uploaded that have "spaces" inside. My developer tools tell me that the background-image is not set correctly, yet the image path is correct and the browser don't have problems finding the image. My question is, can I somehow sanitize the url 'src', so spaces won't be a problem? I am aware of doing this server side, yet I would like to know how to do this with JQuery/JS too. Thanks!

• PHP String to Float

  - by John

  I am not familiar with PHP at all and had a quick question. I have 2 variables @pricePerUnit and @invoicedUnits. Here's the code that is setting these to values: $InvoicedUnits = ((string) $InvoiceLineItem->InvoicedUnits); $pricePerUnit = ((string) $InvoiceLineItem->PricePerUnit); If I output this, I get the correct values. Lets say 5000 invoiced units and 1.00 for price. Now, I need to show the total amount spent. When I multiply these two together it doesn't work (as expected, these are strings). But I have no clue how to parse/cast/convert variables in PHP. What should I do?

• Reference and Value confusion

  - by rgamber

  Hi I read this question on Stack overflow, and tried to do an example. I had the below code: public static void main(String[] args){ int i = 5; Integer I = new Integer(5); increasePrimitive(i); increaseObject(I); System.out.println(i); //Prints 5 - correct System.out.println(I); //Still prints 5 System.out.println(increaseObject2(I)); //Still prints 5 } public static void increasePrimitive(int n){ n++; } public static void increaseObject(Integer n){ n++; } public static int increaseObject2(Integer n){ return n++; } Does the increaseObject print 5 because the value of reference is changing inside that function? Am I right? I am confused why the increasedObject2 prints 5 and not 6. Can anyone please explain?

• Optimal strategy to make a C++ hash table, thread safe

  - by Ajeet

  (I am interested in design of implementation NOT a readymade construct that will do it all.) Suppose we have a class HashTable (not hash-map implemented as a tree but hash-table) and say there are eight threads. Suppose read to write ratio is about 100:1 or even better 1000:1. Case A) Only one thread is a writer and others including writer can read from HashTable(they may simply iterate over entire hash table) Case B) All threads are identical and all could read/write. Can someone suggest best strategy to make the class thread safe with following consideration 1. Top priority to least lock contention 2. Second priority to least number of locks My understanding so far is thus : One BIG reader-writer lock(semaphore). Specialize the semaphore so that there could be eight instances writer-resource for case B, where each each writer resource locks one row(or range for that matter). (so i guess 1+8 mutexes) Please let me know if I am thinking on the correct line, and how could we improve on this solution.

• scope of variables java

  - by qxc

  Is a variable inside the main, a public variable? public static void main(String[] args) { ......... for(int i=0;i<threads.length;i++) try { threads[i].join(); } catch (InterruptedException e) { e.printStackTrace(); } long time=0; .... } i and time are they both public variables? Of course if my reasoning is correct, also any variable belonging to a public method should be considered public.. am i right? Thanks

• Won't connect to the database

  - by user1657958

  I'm confused...I'm using the same code in a different document and in there it's not a problem to get a connection to the database. But in the new document it's just not working...(password, username, database name...all is checked and correct) :-/ <?php define ("DB_HOST", "db1234567.db.hello.com"); // set database host define ("DB_USER", "db1234567"); // set database user define ("DB_PASS","password123"); // set database password define ("DB_NAME","db1234567"); // set database name $link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die("Couldn't make connection."); $db = mysql_select_db(DB_NAME, $link) or die("Couldn't select database"); ?> In the browser I get this: "Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'db1234567'@'123.123.12.12 (using password: YES) in /homepages/12/1234567/test/test.php on line 8 Couldn't make connection." Would be cool if someone could help me :) I'm not seeing any error... Thx!

• My dropdownlist is not selecting an item as expected (MVC 1)

  - by Jen

  OK so I have 2 pages where this kind of behaviour is implemented. It works on one but doesn't work in another and I have no idea why. Despite the data containing a list of selectitems and one of them is selected the dropdown list is not displaying this selection (ie. it resets to the blank item). I don't know how to further debug this. In my page: <%= Html.DropDownList("CampusId", ViewData.Model.Campuses, new { @class = "large search_box" })%> In my controller. Campuses = AdminRepository .ListAll<Campus>(a => a.Description) .ToSelectListItem<Campus>(a => a.CampusId, a => a.Description, criteria.CampusId, true); I can see that campuses does have the correct list item marked as selected - so why when it is displayed on the page is it no longer marked as selected?! I can't see anything else obviously modifying the list. Thanks :)

• Why does php's file_get_contents incorrectly retrieve json files from xkcd?

  - by hally

  In writing a PHP script to download xkcd comics, i incurred errors when trying to get specific comics (as opposed to the latest one). Specifically, pointing file_get_contents at the following url: xkcd.com/$COMIC_NUM/info.0.json inexplicably retrieved the xhtml version of the comic's page on xkcd.com, and not a JSON file. However, if i request the exact same url in my browser, the correct JSON file is downloaded. I'm not sure why this is happening, but i suspect it has something to do with the request headers being sent. Please help! :S

• PHP Math issue with negatives [closed]

  - by user1269625

  Possible Duplicate: PHP negatives keep adding I have this code here.... $remaining = 0; foreach($array as $value=>$row){ $remaining = $remaining + $row['remainingbalance']; } What its doing is that it is going through all the remaining balances in the array which are -51.75 and -17.85 with the code above I get -69.60 which is correct. But I am wondering how when its two negatives if they could subtract? Is that possible? I tried this $remaining = 0; foreach($clientArrayInvoice as $value=>$row){ $remaining = $remaining + abs($row['remainingbalance']); } but it gives me 69.60 without the negative. Anyone got any ideas? my goal is to take -51.75 and -17.85 and come up with -33.90 only when its a negative to do subtract. otherwise add

• Client-server application between two computers in the same network (using boost::asio)

  - by Edwin

  I'm trying to set up a basic communication between my desktop PC and my laptop (latter one using wireless connection) both being in the same network, using the boost::asio tutorials: synchronous client and synchronous server (in c++). When I run both the server and client on the same machine (using the localhost and the datetime port as parameters), it works splendidly. But if I try to set up the laptop as server (tested it with netstat -anb from the command prompt, it is indeed running and listening to port 13 as it's supposed to, and I even deactivated the firewall to make sure it doesn't cause any problems), I cannot connect to it with the client (set up on the PC), no matter what IP I tried (localhost, and basically any IPs that ipconfig -all gave me). So no matter what I tried, I cannot find the correct address that which the client can use to connect to the server. Could anyone help me please?

• How does exactly Qt work?

  - by Somebody still uses you MS-DOS

  I have seen that you can write your application in Qt, and can be run in different operating systems. And - correct me if I'm wrong - you don't need to have Qt installed in all of these plataforms. How does exactly this works? Does Qt compiles to the desired plataform, it bundles some "dlls" (libs), how? Is different from programming a Java application for the sake of cross-plataform? If you use Python to write a Qt application with Python bindings, does the final user needs to have Python installed?

• Can typeid() be used to pass a function?

  - by Kerb_z

  I tried this and got the output as: void Please explain the following Code: #include <cstdio> #include <typeinfo> using namespace std ; void foo() { } int main(void) { printf("%s", typeid(foo()).name());// Please notice this line, is it same as typeid( ).name() ? return 0; } AFAIK: The typeid operator allows the type of an object to be determined at run time. So, does this sample code tell us that a function that returns void is of *type void*. I mean a function is a method and has no type. Correct?

• how do I refactor this to make single function calls?

  - by stack.user.1

  I've been using this for a while updating mysql as needed. However I'm not too sure on the syntax..and need to migrate the sql to an array. Particulary the line database::query("CREATE TABLE $name($query)"); Does this translate to CREATE TABLE bookmark(name VARCHAR(64), url VARCHAR(256), tag VARCHAR(256), id INT) This is my ...guess. Is this correct? class table extends database { private function create($name, $query) { database::query("CREATE TABLE $name($query)"); } public function make($type) { switch ($type) { case "credentials": self::create('credentials', 'id INT NOT NULL AUTO_INCREMENT, flname VARCHAR(60), email VARCHAR(32), pass VARCHAR(40), PRIMARY KEY(id)'); break; case "booomark": self::create('boomark', 'name VARCHAR(64), url VARCHAR(256), tag VARCHAR(256), id INT'); break; case "tweet": self::create('tweet', 'time INT, fname VARCHAR(32), message VARCHAR(128), email VARCHAR(64)'); break; default: throw new Exception('Invalid Table Type'); } } }

• Writing out to a file in scheme

  - by Ceelos

  The goal of this is to check if the character taken into account is a number or operand and then output it into a list which will be written out to a txt file. I'm wondering which process would be more efficient, whether to do it as I stated above (writing it to a list and then writing that list out into a file) or being writing out into a txt file right from the procedure. I'm new with scheme so I apologize if I am not using the correct terminology (define input '("3" "+" "4")) (define check (if (number? (car input)) (write this out to a list or directly to a file) (check the rest of file))) Another question I had in mind, how can I make it so that the check process is recursive? I know it's a lot of asking but I've getting a little frustrated with checking out the methods that I have found on other sites. I really appreciate the help!

• Can we match Any to a generic type? [Scala 2.8]

  - by Jus12

  Please point me to correct link if this has been answered before. I have this code: def getResult(a:Any):Any = a def getAnswer[T](i:Int) = { val result = getResult(i) result match { case t:T => Some(t) case _ => None } } This gives me a unchecked warning and everything matches to T. For instance, when I do getAnswer[Int](2), I get Some(2) (as expected). However, if I do getAnswer[String](2), I also get Some(2) which is not expected (I need None). Is there any way to work around type erasure and somehow get getAnswer to work correctly (i.e., return Some(result) if and only if the result is of type T)? Thanks in advance.

• What is the purpose of @ as part of a member name in C#?

  - by thelaughingdm

  As you can imagine, Googling or Binging for any phrase containing an '@' is difficult. In creating a new web service, one of the members of the imported C# proxy class is prefixed with the @. For example: plan.@event = new Insurance.Event(); I assume that it is Visual Studio's way resolving potential conflicts with reserved words because 'event' is a reserved word. Changing the property in the web service interface to something other than 'event' (i.e. 'healthevent') removes the @ from the property. Is this a correct assumption?

• Question About Classic MVC

  - by kernix

  Hello, In classic MVC the model notifies the view about changes made on it. In C# this means I have to subclass the View I'm interested in and in the subclassed class register to the model's event. For example, if I were to implement MVC using C# and Winforms, I had to subclass TextBox class and then register inside the MyTextBox's constructor for the model events. Am I correct? How was this issued in Smalltalk? Does one also need to subclass every View in order to register the model's events, or is there some way to dynamically add events to the views on the fly? Thanks
