• why it is up to the compiler to decide what value to assign when assigning an out-of-range value to

  - by Allopen

  in C++ Primer 4th edition 2.1.1, it says "when assigning an out-of-range value to a signed type, it is up to the compiler to decide what value to assign". I can't understand it. I mean, if you have code like "char 5 = 299", certainly the compiler will generate asm code like "mov BYTE PTR _sc$[ebp], 43"(VC) or "movb $43, -2(%ebp)"(gcc+mingw), it IS decided by the compiler. but what if we assign a value that is given by the user input? like, via command line? and the asm code generated will be "movb %al, -1(%ebp)"(gcc+mingw) and " mov cl, BYTE PTR _i$[ebp] mov BYTE PTR _sc$[ebp], cl "(VC), so now how can compiler decide what will happen? I think now it is decided by the CPU. Can you give me a clear explanation?

  Hi, I have the following file structure: C:/wamp/myproject/admin/webroot/images I have an index.php file lying inside the admin folder which calls a header.inc.php file lying in the same folder. header.inc.php has the following code- <td align="left" valign="top" class="header-bg"> <table width="100%" border="0" cellspacing="0" cellpadding="0"> index.php calls a css file (css.css) through the following code: <link href="<?php echo (WS_DIR_CSS); ?>/css.css" rel="stylesheet" type="text/css" /> The css lies in the following location: C:/wamp/myproject/admin/webroot/css The css files has a class which has the following code: .header-bg { background:url(../images/header_bg.jpg) left top repeat-x; height:77px; } The image header_bg.jpg is not being displayed in the browser.

• Subquery vs Traditional join with WHERE clause?

  - by BradC

  When joining to a subset of a table, any reason to prefer one of these formats over the other? Subquery version: SELECT ... FROM Customers AS c INNER JOIN (SELECT * FROM Classification WHERE CustomerType = 'Standard') AS cf ON c.TypeCode = cf.Code INNER JOIN SalesReps s ON cf.SalesRepID = s.SalesRepID vs the WHERE clause at the end: SELECT ... FROM Customers AS c INNER JOIN Classification AS cf ON c.TypeCode = cf.Code INNER JOIN SalesReps AS s ON cf.SalesRepID = s.SalesRepID WHERE cf.CustomerType = 'Standard' The WHERE clause at the end feels more "traditional", but the first is arguably more clear, especially as the joins get increasingly complex. Only other reason I can think of to prefer the second is that the "SELECT *" on the first might be returning columns that aren't used later (In this case, I'd probably only need to return cf.Code and Cf.SalesRepID)

• How to use TestAndSet() for solving the critical section problem?

  - by Dan Mantyla

  I'm studying for an exam and I'm having difficulty with a concept. This is the pseudo code I am given: int mutex = 0; do { while (TestAndSet(&mutex)); // critical section mutiex = 0; // remainder section } while (TRUE); My instructor says that only two of the three necessary conditions (mutual exclusion, progress, and bounded waiting) are met with this code, but I don't understand which one isn't being met...?? How should the code be modified to support the missing condition to solve the critical region problem? Thanks in advance for any insight!

• Generating pagination links

  - by alpheus

  I am trying to implement a paging system that displays nearby page numbers as well as pages at each extreme. For example, if the user is on page 20 of 40, the following links should be displayed: 1, 2 ... 18, 19, [20], 21, 22 ... 39, 40. The solution would be similar to the one described here: http://90poe.com/alex-lee-on-bell-curve-pagination I have seen code to do this in PHP, but not in ASP.net (ideally I am looking for C# code). If anyone has done anything like this previously, it would be very helpful to see your code.

• Safe ASCII char to replace whitespace before storing

  - by AngryWhenHungry

  My code passes a big bunch of text data to a legacy lib, which is responsible for storing it. However, it tends to remove trailing whitespace. This is a problem when I read the data back. Since I cannot change the legacy code, I thought about replacing the all spaces with some uncommon ASCII character. When I read back the text, I can replace them back. Is this a bad idea, considering that I cannot touch the legacy storage code? Which character can I use as a substitute? I was considering some char upwards of 180. There will only be spaces - no tabs or newlines - in the data. The data is alphanumeric, with special characters.

• Expected symbol problems with this function declaration

  - by Derek

  I am just getting back into the C programming realm and I am having an issue that I think is linker related. I am using cmake for the first time as well, so that could be adding to my frustration. I have included a third party header file that contains a typedef that my code is trying to use, and it has this line: typedef struct a a_t so my code has a_t *var; //later..... var->member;// this line throws the error which throws the error: dereferencing pointer to incomplete type So am I just missing another include file, or is this a linker issue? I am building this code in QtCreator and using cmake. I can dive on a_t to see that typedef declaration in the included header, but I can't seem to dive on "struct a" itself to see where it's coming from. Thanks

• Help Fix a bug - Unexpected T_STRING

  - by thecoshman

  So I have just rebuilt my server, just on local network. Stick my site back on it, try to run the code, and I get a anice T_STRING error. This is all very strange, as I have not changed the code :S <?php $window_ID = -1; if(isset($_POST["window_ID"]) AND $_POST["window_ID"] != null){ $window_ID = trim($_POST["window_ID"]); } ?> This is the start of the file, apter this rather loverly snipit of PHP the rest is just XMl, yet on line 6 appertnlty there is an unexpected T_STRING, which is strange considering all that is on that line is the ?>, then the XML starts up... Any one got any ideas what has gone wrong here? Any chance it ould be magic quotes? I had turned it of before, but I want to now update my code to check for the magic quotes and avoid its stupid actions.

• How to use YT thumb in plugin

  - by Frank Morrison

  I'm using two plugins on my wordpress site: Auto post youtube Pulls a youtube video then drafts it for me. I use this on my index page beside the post code and the thumbnail appears great: <?php tern_wp_youtube_image(); ?> Top Ten Which I use to display the most viewed posts on a page. Not looking great at the moment, but will fix styling later. This is the code to display popular posts: <?php if(function_exists('tptn_show_pop_posts')) tptn_show_pop_posts(); ?> Is it possible for me to use the youtube image in the popular post function? Or is it because they are seperate they cannot work together without a lot of code? Thanks in advance! Some links incase anybody wants to check them out http://wordpress.org/extend/plugins/top-10/ http://www.ternstyle.us/products/plugins/wordpress/wordpress-automatic-youtube-video-posts/wordpress-automatic-youtube-video-posts-functions

• iPhone SDK: How do I programatically change the background image of a UIButton added to a NIB?

  - by user304583

  I've seen several questions/answers related to entirely creating a button in code, but not one which would let me know how to change the button image in code, when I originally added the button to my NIB in Interface Builder. I know how to change the background in Interface Builder.. but I want to change it in code, so I can change it automagically. Any help really appreciated! Perhaps the answer is so obvious nobody needs to ask.. if so please forgive the dweeb that I am and help! :-)

• is "Object();" a predefined function in javascript?

  - by Qlidnaque

  I come across code such as "personObj=new Object();" where a new object called personObj is being defined. What I'm trying to find out is whether Object() is a prefined function in javascript, because I understand by using the mentioned code, a instance of a class is being formed but in the example code where I'm studying from, the class Object() is not being defined anywhere, so I was wondering if Object() was a predefined function in javascript and whether I can be directed to some online resources, as all that shows up in google when I try to find Object() are articles in general javascript object oriented programming.

• Profiling help required

  - by Mick

  I have a profiling issue - imagine I have the following code... void main() { well_written_function(); badly_written_function(); } void well_written_function() { for (a small number) { highly_optimised_subroutine(); } } void badly_written_function() { for (a wastefully and unnecessarily large number) { highly_optimised_subroutine(); } } void highly_optimised_subroutine() { // lots of code } If I run this under vtune (or other profilers) it is very hard to spot that anything is wrong. All the hotspots will appear in the section marked "// lots of code" which is already optimised. The badly_written_function() will not be highlighted in any way even though it is the cause of all the trouble. Is there some feature of vtune that will help me find the problem? Is there some sort of mode whereby I can find the time taken by badly_written_function() and all of its sub-functions?

• Submit multiple forms as one

  - by Stephen Sarcsam Kamenar

  I have two forms on the page. To the user it looks like 1 form, and I actually wish it was one form. But the way I'm trying to reuse code and include things, I can't avoid two forms in the source code... trying to act as one. I don't want to do ajax submit, I want a normal post submit, my form handler has redirects in it. How can I submit both of these, and get values that make sense on the server side. something like $_POST['form1]['whatever'] $_POST['form2]['thing'] Maybe take all the inputs from form 2, rename all of them with a prefix, and append them to form 1? I can't find a non-messy way of doing this. I don't think I need code, just a plan. Least messy idea wins.

• How to get the class of an input inside a jQuery each loop?

  - by Paul Atkins

  Hi, I have function which appends inputs inside a list item when a link is clicked. I then loop through these inputs using an each loop using the code below. It is working correctly as shown, however instead of using field.name I want to use the class of the input as the array key but when i try to do this the class is shown as undefined. Here is the code I am currently using: var values = {}; $.each($('li :input').serializeArray(), function(i, field) { values[field.name] = field.value; }); Here is the code I have inside the list item once I have appended the hidden inputs using jQuery append: <li><input type="hidden" name="group" class="group" value="2"/><input type="hidden" name="condition" class="condition" value="isany"/><input type="hidden" name="value" class="value" value="1,2"/></li> I can get the name attribute fine but class is always undefined. Could anybody help with this?

  How can i call a function form a variable. var upfunction = init; //or var upfunction = init(); I have tried the above code and it does not work.

Sorry if this is a noob question but all i do is copy and paste code i have found.

• HTML block nested in PHP if statement - is this considered bad practice?

  - by JYelton

  Consider the following example: <table> <tr> <td>Row One</td> </tr> <?php if ($rowtwo) { ?> <tr> <td>Row Two</td> </tr> <?php } ?> </table> If $rowtwo is true, the second row is output, otherwise it is skipped. The code works as desired, however I am evaluating Netbeans (7 beta) as a PHP IDE (instead of just using a text editor). Netbeans flags the code with an error: Misplaced non-space characters insided [sic] a table. Should I consider an alternate way of writing this code, or is Netbeans incapable of understanding this flow control wrapper for HTML output?

• non-CDN Hosted jQuery caused strange some behaviour

  - by kwokwai

  Hi all, I was using this JQuery in this download link, and included it in the head tag of a HTML web page: <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> In a php web page, I got these few lines of codes: $.ajax({ url: 'http://mywebsite.com/site1/toavail/, type: "post", success: function(data) { // some more code here } }); When I tested the HTML page in IE 6, and 7, I saw the same warning message: "permission denied" When I tested it in Firefox 3, nothing was returned from the server web page. Later, I changed the JQuery source link to be: http://code.jquery.com/jquery-1.4.2.js then I refreshed the web page, and I could saw the returned value.

• Why call iframe from javascript

  - by sammville

  I want to know why some ad codes or embed codes don't directly give you iframe code to embed on your site instead they give a javascript code which links to another javascript file on their server. The file on their server calls the iframe which serves the content. Why is this done and what are the benefits of this method. Example: this is the code issued by amazon: <script type="text/javascript" src="http://www.assoc-amazon.co.uk/s/ads.js"></script> Which opens another javascript file that calls the iframe.

• Confused by "let" in Clojure

  - by Tom Dalling

  I just started playing with Clojure, and I wrote a small script to help me understand some of the functions. It begins like this: (def *exprs-to-test* [ "(filter #(< % 3) '(1 2 3 4 3 2 1))" "(remove #(< % 3) '(1 2 3 4 3 2 1))" "(distinct '(1 2 3 4 3 2 1))" ]) Then it goes through *exprs-to-test*, evaluates them all, and prints the output like this: (doseq [exstr *exprs-to-test*] (do (println "===" (first (read-string exstr)) "=========================") (println "Code: " exstr) (println "Eval: " (eval (read-string exstr))) ) ) The above code is all working fine. However, (read-string exstr) is repeated so I tried to use let to eliminate the repetition like so: (doseq [exstr *exprs-to-test*] (let [ex (read-string exstr)] ( (do (println "===" (first ex) "=========================") (println "Code: " exstr) (println "Eval: " (eval ex)) ) )) ) But this works once for the first item in *exprs-to-test*, then crashes with a NullPointerException. Why is the addition of let causing the crash?

• C# - Printing out groupnames, items and subitems in a loop?

  - by Nike

  What I'm trying to do, is to store all groupnames, items and subitems from a listview into a string. Take a look at the following screenshot. I'm kind of stuck though, with the loop. I'm pretty sure i can figure out how to actually store it in a variable though. The following code will loop through all of the listview Items: int countGroups = csslistview.Items.Count; foreach (ListViewItem lvi in csslistview.Items){ //code here countGroups++; } But i can't figure out how to loop through all of the Groups. I tried this, but it's not working: int countGroups = csslistview.Groups.Count; foreach (ListViewItem lvi in csslistview.Items){ //code here countGroups++; } I'm trying to echo it out as CSS, if you're wondering. The grouname is the id/class/tag, the item is the rule, and the subitem is the property. So, any ideas?

• Auto Re-Running of Tests that fail

  - by Tangopop

  I have a set of Selenium/MbUnit Tests that work fine, but tend to take a while to run (over 4 hours) A problem i am finding is that about 1 in 20 test seems to timeout when running. I have confirmed the Selenium GRID is working and the Selenium RC's are all fine, it just seems to be a qwerk of the system. What is really annoying though is that if i run these tests again they will usually pass. What i want to know is if there is a way for me to auto rerun the tests (probably in the code) if a perticular type of exception is caught... I have attempted to put a few lines of code in the catch statement but i know this is a very hacky way of re running the tests. Here is the code: catch (AssertionException e) { if (e.Message() == "TimeOut") //Something similar to this { this.Test(); } else { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } } Any suggestions?
