  • Referencing invalid memory locations with C++ Iterators

    - by themoondothshine
    I am a big fan of GCC, but recently I noticed a vague anomaly. Using __gnu_cxx::__normal_iterator (ie, the most common iterator type used in libstdc++, the C++ STL) it is possible to refer to an arbitrary memory location and even change its value without causing an exception! Is this expected behavior? If so, isn't a security loophole? Here's an example: #include <iostream> using namespace std; int main() { basic_string<char> str("Hello world!"); basic_string<char>::iterator iter = str.end(); iter += str.capacity() + 99999; *iter = 'x'; cout << "Value: " << *iter << endl; }

  • how to set and access variable values from another classess

    - by BittenApple
    I am modifying QuartzDemo example app and want to do set and read values of integer type variables in other classes which are already included. For example, in MainViewController.m I want to set a numeric value (simple numbers from 1-100) to a variable which is then going to be called (read) in file QuartzImages.m. Question is how to define variable properly, set and access (read) the value. I am a beginner with Obj C and iPhone SDK in general and have some experience with Delphi and VB but this doesn't help at all :) Thank you, whoever and wherever you are, person who will take me out of this endless googling loop.

  • trying to set a dropdown in MVC

    - by RJ
    I almost have this solved but need a little push. Here's what I have: In the database I have a field called active that is a bit field (True/False) I have placed a dropdownlist on the View form like this: <%= Html.DropDownList("lstActive", new SelectList((IEnumerable)ViewData["ActiveList"])) %> In my controller, I simply have this code to generate the True/False in the dropdown: List<string> activeList = new List<string>(); activeList.Add("True"); activeList.Add("False"); ViewData["ActiveList"] = new SelectList(activeList); I want to bind to the field in the database called active and select it in the dropdown. When I view it like this I get this: So the questions are these: Obviously I am not pointing to the Value and Text property but what is that in this case? And how do I select the value that is in the database? Any help would be appreciated.

  • String Object. Clarification needed

    - by mac
    Guys, help me clarify. Say i have the following line in my program: jobSetupErrors.append("abc"); In the case above where jobSetupErrors is a StringBuilder(), what i see happen is: New String Object is created and assigned value "abc" value of that String object is assigned to the existing StringBuilder object If that is correct, and I add 1 more line ... jobSetupErrors.append("abc"); logger.info("abc"); In the above example are we creating String object separately 2 times? If so, would it be more proper to do something like this? String a = "abc"; jobSetupErrors.append(a); logger.info(a); Is this a better approach? Please advise

  • How do I guarantee row uniqueness in MySQL without the use of a UNIQUE constraint?

    - by MalcomTucker
    Hi I have some fairly simple requirements but I'm not sure how I implement them: I have multiple concurrent threads running the same query The query supplies a 'string' value - if it exists in the table, the query should return the id of the matching row, if not the query should insert the 'string' value and return the last inserted id The 'string' column is (and must be) a text column (it's bigger than varchar 255) so I cannot set it as unique - uniqueness must be enforced through the access mechanism The query needs to be in stored procedure format (which doesnt support table locks in MySQL) How can I guarantee that 'string' is unique? How can I prevent other threads writing to the table after another thread has read it and found no matching 'string' item? Thanks for any advice..

  • An RMIPRoxyFactoryBean factory in Spring?

    - by Robert Munteanu
    I'm currently using a Spring RmiProxyFactoryBean to access remote services. Since requirements have changed, I need to specify at runtime a different host - there can be many of them - , but the remoteServiceInterface and the non-host components of the remoteServiceUrl remain the same. Conceptually speaking, I'd see a bean definition similar to: <bean class="org.springframework.remoting.rmi.RmiProxyFactoryBeanFactory"> <property name="serviceInterface" value="xxx"/> <property name="serviceUrl" value="rmi://#{HOST}:1099/ServiceUrl"/> </bean> which exposes a Object getServiceFor(String hostName); Is there such a service available with Spring? Alternatively, do you see another way of doing this? Please note that the host list will not be known at compile or startup time, so I can't generate it in the xml file.

  • How to use LINQ To Entities for filtering when many methods are not supported?

    - by Kinderchocolate
    Hi, I have a table in SQL database: ID Data Value 1 1 0.1 1 2 0.4 2 10 0.3 2 11 0.2 3 10 0.5 3 11 0.6 For each unique value in Data, I want to filter out the row with the largest ID. For example: In the table above, I want to filter out the third and fourth row because the fifth and sixth rows have the same Data values but their IDs (3) are larger (2 in the third and fourth row). I tried this in Linq to Entities: IQueryable<DerivedRate> test = ObjectContext.DerivedRates.OrderBy(d => d.Data).ThenBy(d => d.ID).SkipWhile((d, index) => (index == size - 1) || (d.ID != ObjectContext.DerivedRates.ElementAt(index + 1).ID)); Basically, I am sorting the list and removing the duplicates by checking if the next element has an identical ID. However, this doesn't work because SkipWhile(index) and ElementAt(index) aren't supported in Linq to Entities. I don't want to pull the entire gigantic table into an array before sorting it. Is there a way?

  • Exploding a range of dates with LINQ

    - by Robert Gowland
    If I have a pair of dates, and I want to generate a list of all the dates between them (inclusive), I can do something like: System.DateTime s = new System.DateTime(2010, 06, 05); System.DateTime e = new System.DateTime(2010, 06, 09); var list = Enumerable.Range(0, (e - s).Days) .Select(value => s.AddDays(value)); What I'm stuck on is that I've got a list of pairs of dates that I want to explode into a list of all the dates between them. Example: {2010-05-06, 2010-05-09}, {2010-05-12, 2010-05-15} should result in {2010-05-06, 2010-05-07, 2010-05-08, 2010-05-09, 2010-05-12, 2010-05-13, 2010-05-14, 2010-05-15} Note the pairs of dates are guaranteed not to overlap each other.

  • Mapping restful ajax requests to spring

  • PHP - BUG with filter_var and FILTER_VALIDATE_FLOAT

    - by Samuele
    I think there is a bug in this filter_var or maybe I'm doing something wrong: Try this: $options = array( 'options' => array( 'default' => 3, 'min_range' => 1000.0, 'max_range' => 5000.6, ) ); $VariableValue2 = 5698; $VariableValue4 = 5698.2; $chicco3 = filter_var($VariableValue2, FILTER_VALIDATE_INT, $options); $chicco4 = filter_var($VariableValue4, FILTER_VALIDATE_FLOAT, $options); It suppose to don't validate it... Infact the value: 5698 is greater than 5000.6!!!! But with FILTER_VALIDATE_INT it work FINE!! It return 3 that is the default value in case it don't validate it... PERFECT... Instead, with FILTER_VALIDATE_FLOAT it validate it... It return 5698.2!!! I'm doing something wrong??? Thank you to everybody... Samuele

  • h:selectOneMenu not populating a 'selected' item

    - by dann.dev
    I'm having trouble with an h:selectOneMenu not having a selected item when there is already something set on the backing bean. I am using seam and have specified a customer converter. When working on my 'creation' page, everything works fine, something from the menu can be selected, and when the page is submitted, the correct value is assigned and persisted to the database as well. However when I work on my 'edit' page the menu's default selection is not the current selection. i have gone through and confirmed that something is definitely set etc. My selectOneMenu looks like this: <h:selectOneMenu id="selVariable" value="#{customer.variableLookup}" converter="#{variableLookupConverter}"> <s:selectItems var="source" value="#{customerReferenceHelper.variableLookups()}" label="#{source.name}" /> </h:selectOneMenu> And the converter is below. It very simple and just turns the id from string to int and back etc: @Name( "sourceOfWealthLookupConverter" ) public class SourceOfWealthLookupConverter implements Serializable, Converter { @In private CustomerReferenceHelper customerReferenceHelper; @Override public Object getAsObject( FacesContext arg0, UIComponent arg1, String arg2 ) { VariableLookup variable= null; try { if ( "org.jboss.seam.ui.NoSelectionConverter.noSelectionValue".equals( arg2 ) ) { return null; } CustomerReferenceHelper customerReferenceHelper = ( CustomerReferenceHelper ) Contexts.getApplicationContext().get( "customerReferenceHelper" ); Integer id = Integer.parseInt( arg2 ); source = customerReferenceHelper.getVariable( id ); } catch ( NumberFormatException e ) { log.error( e, e ); } return variable; } @Override public String getAsString( FacesContext arg0, UIComponent arg1, Object arg2 ) { String result = null; VariableLookup variable= ( VariableLookup ) arg2; Integer id = variable.getId(); result = String.valueOf( id ); return result; } } I've seen a few things about it possibly being the equals() method on the class, (that doesn't add up with everything else working, but I overrode it anyway as below, where the hashcode is just the id (id is a unique identifier for each item). Equals method: @Override public boolean equals( Object other ) { if ( other == null ) { return false; } if ( this == other ) { return true; } if ( !( other instanceof VariableLookup ) ) { return false; } VariableLookup otherVariable = ( VariableLookup ) other; if ( this.hashCode() == otherVariable.hashCode() ) { return true; } return false; } I'm at my wits end with this, I can't find what I could have missed?! Any help would be much appreciated

  • How do I get this php statement that gets all the values from database and outputs as checkboxes to

    - by ggfan
    I am a bit lost in all these "" and '' and . in this statement. Basically this query is to get all the tagname from table "tag" and display them for the users as checkboxes. If they have clicked 'submit' and they missed another field(say the title of a post), it would still have the tag they chose displayed. The part I need help with is the echoing part. It doesn't seem to remember the tag when they click submit. $query4 = "SELECT * FROM tags ORDER BY tagname"; $data4 = mysqli_query($dbc, $query4); while ($row4 = mysqli_fetch_array($data4)) { echo "<li><input type='checkbox' name='postingtag[]'"; if (!empty($postingtag)){ echo "value='$postingtag'"; } else{ echo "value='{$row4['tagID']}'"; } echo ">{$row4['tagname']}</li>"; }

  • __defineSetter__ on innerHTML stops it from rendering

    - by Tokimon
    Hi, i'm trying to create a watch method for HTML elements, using __define[GS]etter__ when a property is changed. It reacts just fine when i set the value, but if the property listened to, is innerHTML, it somehow fails to render the given string. So basically, when im adding something to innerHTML it doesn't show. Im using the watch method described in this previous question: http://stackoverflow.com/questions/1269633/javascript-watch-for-object-properties-changes I could of cause just not listen to innerHTML changes, but i'm also wondering if the __defineSetter__ somehow prevents original handling of setting the value. Thanks!

  • In SQL, how can I count the number of values in a column and then pivot it so the column becomes the

    - by Josh Yeager
    I have a survey database with one column for each question and one row for each person who responds. Each question is answered with a value from 1 to 3. Id Quality? Speed? -- ------- ----- 1 3 1 2 2 1 3 2 3 4 3 2 Now, I need to display the results as one row per question, with a column for each response number, and the value in each column being the number of responses that used that answer. Finally, I need to calculate the total score, which is the number of 1's plus two times the number of 2's plus three times the number of threes. Question 1 2 3 Total -------- -- -- -- ----- Quality? 0 2 2 10 Speed? 2 1 1 7 Is there a way to do this in set-based SQL? I know how to do it using loops in C# or cursors in SQL, but I'm trying to make it work in a reporting tool that doesn't support cursors.

  • Why can't I open a new window on my jquery ajax callback?

    - by KyleGobel
    to show my problem in a couple examples... THIS WORKS $.post("SomePage.aspx", { name : "value" }, function (data) { alert(data); }, "text"); THIS DOESN'T WORK $.post("SomePage.aspx", { name : "value" }, function (data) { window.open("http://www.google.com"); }, "text"); In the first example, I get alerted with what i'm expecting. In the second example, nothing happens. No window is opened. If I add an alert or something before or after the window.open call, the alert works fine, but the window doesn't open. If I add a window.open completly after the $.post method, the window opens fine (of course this doens't help me at all). I'm wondering why I can't open a window in the callback. What do I have to do to be able to open a window? I'd like to open a window to show some fancy results. Any help is appreciated, thanks.

  • What ports, besides 80, need to be available to send (only send) email using phpmailer to gmail over SSL?

    - by Wobblefoot
    Using phpmailer I keep getting a 110 timeout and "Unable to connect to host" when sending email from my web server. The authentication details are right and they work on another server I have (login, pwd, ports etc and gmail acct set up for SSL connections on 465), but it's failing on my new server. FIREWALL: I allow related/established, port 80 and a port for SSH on INPUT, then this on OUTPUT: 7906 474K DROP tcp -- any any anywhere anywhere tcp dpt:smtp 0 0 ACCEPT tcp -- any any localhost.localdomain yw-in-f109.1e100.net tcp dpt:submission 0 0 ACCEPT tcp -- any any localhost.localdomain gx-in-f109.1e100.net tcp dpt:ssmtp 0 0 DROP tcp -- any any anywhere anywhere tcp dpt:submission 9 540 DROP tcp -- any any anywhere anywhere tcp dpt:ssmtp This output chain works on my other server and disabling it doesn't get mail delivered either. WEB SERVER: Varnish (80) Nginx (8088) Drupal 7 PHP5-FPM APC MySQL All works beautifully, except for outgoing email. What else could it be? I understand phpmailer does NOT require a local MTA or procmail (this is sort of the point - I don't want the security or admin overhead of a full blown MTA on my web server). Am I wrong? Do I need an MTA as well? What local ports and programs are used to authenticate over SSL and route mail using phpmailer? Any ideas at all greatly appreciated - wasted a day on this nonsense already!

  • Flex RGBA colors in CSS

    Hello all, I am trying to style a DataGrid component so that the background is transparent (Flex 4). Rgba colors work fine if I make "alternatingItemColors" an attribute on the component, but if I try to declare it in my css stylesheet, I cannot declare the alpha value. Works (mxml): <mx:DataGrid id="songGrid" width="800" height="529" dataProvider="{songs}" itemClick="handleRowClick(event);" x="145" y="168" headerStyleName="dataGridHeader" alternatingItemColors="[0xFFFFFFFF, 0xFFFFFFFF]"> Doesn't Work (css): mx|DataGrid { alternatingItemColors: #FFFFFFFF, #FFFFFFFF; } If I enter the values as "0xFFFFFFFF", I get a parse error, because it's not proper css (of course, most of flex's css isn't proper css, but I digress...). So, is there any way to declare the alpha value of these colors in the css?
