• drupal themes: .info file: how do I add more than 1 css file / js file to my theme?

  - by egarcia

  I'm creating a new Drupal theme. Until now, I only needed to include a single css file and a single js file. So my theme.info file had something like this: stylesheets[all][] = css/style.css scripts[] = js/script.js Now I must include jquery and jquery-ui in order to use a calendar date. These come with 2 new javascript files, and 1 additonal css file that I must add to the site. The calendar input form is going to be used in all pages (on a side block) so it is ok for me to load the extra css/javascript on all pages. I think the easiest thing would be to reference them on the .info file itself. At first I tried to just put them there with separate spaces: stylesheets[all][] = css/style.css css/ui-lightness/jquery-ui-1.8.1.custom.css scripts[] = js/jquery-1.4.2.min.js js/jquery-ui-1.8.1.custom.min.js js/reservations.js I emptied drupal's cache and... none of them loaded. I then tried separating each file with a comma, and flushing the cache again. Same result. I've browsed some drupal pages, but could not find how to add several javascript/css files on one theme (they always seem to add just 1 of each). So, how do I include several css/javascript files on the .info file?

• What's keeping this timer in scope? The anonymous method?

  - by Andy

  Ok, So I have a method which fires when someone clicks on our Icon in a silverlight application, seen below: private void Logo_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { e.Handled = true; ShowInfo(true); DispatcherTimer autoCloseTimer = new DispatcherTimer(); autoCloseTimer.Interval = new TimeSpan(0, 0, 10); autoCloseTimer.Tick +=new EventHandler((timerSender,args) => { autoCloseTimer.Stop(); ShowInfo(false); }); autoCloseTimer.Start(); } Whats meant to happen is that the method ShowInfo() opens up a box with the company info in and the dispatch timer auto closes it after said timespan. And this all works... But what I'm not sure about is because the dispatch timer is a local var, after the Logo_MouseLeftButtonUp method finishes, what is there to keep the dispatch timer referenced and not availible for GC collection before the anonymous method is fired? Is it the reference to the ShowInfo() method in the anonymous method? Just feels like some thing I should understand deeper as I can imagine with using events etc it can be very easy to create a leak with something like this. Hope this all makes sense! Andy.

• Wicket: How to implement an IDataProvider/LoadableDetachableModel for indexed lists

  - by cretzel

  What's the best way to implement an IDataProvider and a LoadableDetachable in Wicket for an indexed list? Suppose I have a Customer who has a list of Adresses. class Customer { List adresses; } Now I want to implement a data provider/ldm for the adresses of a customer. I suppose the usual way is an IDataProvider as an inner class which refers to the customer model of the component, like: class AdressDataProvider implements IDataProvider { public Iterator iterator() { Customer c = (Customer)Component.this.getModel(); // somehow get the customer model return c.getAdresses().iterator(); } public IModel model(Object o) { Adress a = (Adress) o; // Return an LDM which loads the adress by id. return new AdressLoadableDetachableModel(a.getId()); } } Question: How would I implement this, when the adress does not have an ID (e.g. it's a Hibernate Embeddable/CollectionOfElements) but can only be identified by its index in the customer.adresses list? How do I keep reference to the owning entity and the index? In fact, I know a solution, but I wonder if there's a common pattern to do this.

• Cocoa framework development: sharing between projects

  - by e.James

  I am currently developing a handful of similar Cocoa desktop apps. In an effort to share code between them, I have identified a set of core classes and functions that can be common across all of these applications. I would like to bundle this common code into a framework which all of my current applications (and any future ones) can link against. Now, here's the hard part: I'm going to be developing this framework as I go, so I need each of my desktop apps to have a reference to it, but I want to be able to edit the framework source code from within each of the app projects and have the framework automatically rebuilt as required. For example, let's say I have the Xcode project for DesktopAppNumberOne open, and I decide that one of my framework classes needs to be changed. I would like to: Open and edit the source file for that framework class without having to open the framework project in Xcode. Hit "build" on DesktopAppNumberOne, and see the framework rebuilt first (because one of its sources has changed), then see parts of DesktopAppNumberOne rebuilt (because one of the frameworks it links against has changed). I can see how to do this with only one app and one framework, but I'm having trouble figuring out how to do it with multiple apps that share a single framework. Has anyone had success with this approach? Am I perhaps going about this the wrong way? Any help would be appreciated.

• How can I change the VisualState in a View from the ViewModel?

  - by Decker

  I'm new to WPF and MVVM. I think this is a simple question. My ViewModel is performing an asynch call to obtain data for a DataGrid which is bound to an ObservableCollection in the ViewModel. When the data is loaded, I set the proper ViewModel property and the DataGrid displays the data with no problem. However, I want to introduce a visual cue for the user that the data is loading. So, using Blend, I added this to my markup: <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="LoadingStateGroup"> <VisualState x:Name="HistoryLoading"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="HistoryGrid"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Hidden}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="HistoryLoaded"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="WorkingStackPanel"> <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Hidden}"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> I think I know how to change the state in my code-behind (something similar to this): VisualStateManager.GoToElementState(LayoutRoot, "HistoryLoaded", true); However, the place where I want to do this is in the I/O completion method of my ViewModel which does not have a reference to it's corresponding View. How would I accomplish this using the MVVM pattern?

• XForms relation of 'constraint' and 'required' properties

  - by Danny

  As a reference, the most similar question already asked is: http://stackoverflow.com/questions/8667849/making-xforms-enforce-the-constraint-and-type-model-item-properties-only-when-fi The difference is that I cannot use the relevant properties since I do want the field to be visible and accessible. I'm attempting to make a XForms form that has the following properties: It displays a text field named 'information'. (for the example) This field must not be required, since it may not be necessary to enter data. (Or this data will be entered at a later time.) However, if data is entered in this field, it must adhere to the specified constraint. I cannot mark the field as not relevant since this would hide the field and some data may need to be entered in it. The trouble now is that even though the field has no data in it, the constraint is still enforced (i.e. even though it is not marked as 'required'). I have taken a look at the XForms 1.1 specification, however it does not seem to describe how the properties 'required' and 'constraint' should interact. The only option I see, is to add a part to the constraint such that an empty value is allowed. e.g.: . = '' or <actual-constraint However, I don't like this. It feels like a workaround to add this to every such field. Is there any other way to express that non-required fields should not need to match the constraint for that field? (Am I missing something?)

• How to get SimpleRpcClient.Call() to be a blocking call to achieve synchronous communication with RabbitMQ?

  - by Nick Josevski

  In the .NET version (2.4.1) of RabbitMQ the RabbitMQ.Client.MessagePatterns.SimpleRpcClient has a Call() method with these signatures: public virtual object[] Call(params object[] args); public virtual byte[] Call(byte[] body); public virtual byte[] Call(IBasicProperties requestProperties, byte[] body, out IBasicProperties replyProperties); The problem: With various attempts, the method still continues to not block where I expect it to, so it's unable ever handle the response. The Question: Am I missing something obvious in the setup of the SimpleRpcClient, or earlier with the IModel, IConnection, or even PublicationAddress? More Info: I've also tried various paramater configurations of the QueueDeclare() method too with no luck. string QueueDeclare(string queue, bool durable, bool exclusive, bool autoDelete, IDictionary arguments); Some more reference code of my setup of these: IConnection conn = new ConnectionFactory{Address = "127.0.0.1"}.CreateConnection()); using (IModel ch = conn.CreateModel()) { var client = new SimpleRpcClient(ch, queueName); var queueName = ch.QueueDeclare("t.qid", true, true, true, null); ch.QueueBind(queueName, "exch", "", null); //HERE: does not block? var replyMessageBytes = client.Call(prop, msgToSend, out replyProp); } Looking elsewhere: Or is it likely there's an issue in my "server side" code? With and without the use of BasicAck() it appears the client has already continued execution.

• How does someone without a CS degree get an interview in a sluggish economy?

  - by Anon

  I've been programming off and on since 4th grade (for about 20 years). Technology is one of my passions but after working in the field for a couple years out of High School, I spent nine months and $15,000 getting an accredited certificate in music performance instead of CS. I've been doing lots of self study but I think a CS degree is overkill for most line of business applications. Even so, HR departments can't be expected to know that... How does one get their foot in the proverbial door without a degree, especially in a smaller "fly-over country" market? ...or... Where can I get the cheapest/easiest degree that will pass muster (including testing out of as much as possible)? Don't get me wrong, I'm down with learning new things but I don't necessarily need the expense or coaching to motivate me. EDIT Consolidating good answers: Networking/User Groups Portfolio/Open Source Contributions Look for hybrid jobs (How I got my start :) ) Seek un-elitist companies/hiring managers. (Play the numbers game) Start my own business. (This is a bit challenging for a family man but a very good answer. My reason for searching is to reduce my commute thereby allowing more time to cultivate income on the side) Avail myself of political subsidies to constituents in the teachers' unions ;) .

• Silverlight WinDg Memory Release Issue

  - by Chris Newton

  Hi, I have used WinDbg succesfully on a number of occasions to track down and fix memory leaks (or more accurately the CLRs inability to garbage collect a released object), but am stuck with one particular control. The control is displayed within a child window and when the window is closed a reference to the control remains and cannot be garbage collected. I have resolved what I believe to be the majority of the issues that could have caused the leak, but the !gcroot of the affected object is not clear (to me at least) as to what is still holding on to this object. The ouput is always the same regardless of the content being presented in the child window: DOMAIN(03FB7238):HANDLE(Pinned):79b12f8:Root: 06704260(System.Object[])- 05719f00(System.Collections.Generic.Dictionary2[[System.IntPtr, mscorlib],[System.Object, mscorlib]])-> 067c1310(System.Collections.Generic.Dictionary2+Entry[[System.IntPtr, mscorlib],[System.Object, mscorlib]][])- 064d42b0(System.Windows.Controls.Grid)- 064d4314(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4360(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3860(System.Windows.Controls.Border)- 064d4218(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d4264(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3bfc(System.Windows.Controls.ContentPresenter)- 064d3d64(System.Collections.Generic.Dictionary2[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]])-> 064d3db0(System.Collections.Generic.Dictionary2+Entry[[MS.Internal.IManagedPeerBase, System.Windows],[System.Object, mscorlib]][])- 064d3dec(System.Collections.Generic.Dictionary2[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]])-> 064d3e38(System.Collections.Generic.Dictionary2+Entry[[System.UInt32, mscorlib],[System.Windows.DependencyObject, System.Windows]][])- 06490b04(Insurer.Analytics.SharedResources.Controls.HistoricalKPIViewerControl) If anyone has any ideas about what could potentially be the problem, or if you require more information, please let me know.

• PHP JQuery: Where to specify uploadify destination folder

  - by Eamonn

  I have an uploadify script running, basic setup. Works fine when I hard code the destination folder for the images into uploadify.php - now I want to make that folder dynamic. How do I do this? I have a PHP variable $uploadify_path which contains the path to the folder I want. I have switched out my hard coded $targetPath = path/to/directory for $targetPath = $uploadify_path in both uploadify.php and check_exists.php, but it does not work. The file upload animation runs, says it is complete, yet the directory remains empty. The file is not hiding out somewhere else either. I see there is an option in the Javascript to specify a folder. I tried this also, but to no avail. If anyone could educate me on how to pass this variable destination to uploadify, I'd be very grateful. I include my current code for checking (basically default): The Javascript <script type="text/javascript"> $(function() { $('#file_upload').uploadify({ 'swf' : 'uploadify/uploadify.swf', 'uploader' : 'uploadify/uploadify.php', // Put your options here }); }); </script> uploadify.php $targetPath = $_SERVER['DOCUMENT_ROOT'] . $uploadify_path; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetFile = $targetPath . $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('jpg','jpeg','gif','png'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } }

• xcode project-/target-settings-syntax for linker flag force_load on iPhone

  - by Kaiserludi

  Hi all. I am confronted with the double bind, that on the one hand for one of the 3rd party static libraries, my iPhone application uses, the linker flag -all_load has to be set in the application project- or target settings, otherwise the app crashes at runtime not finding some symbols, called internally from the lib, on the other hand for another 3rd party static lib -all_load must not be set on application level, or the app won't build thanks to a "duplicate symbols"-linker error. To solve this issue I now want to use force_load instant of load_all, as it due to documentation it does the same like all_load, but only for the passed path or lib-file, instead of all libs. The problem with force_load is, I do not have a clue, how to pass a path or file as parameter with it, when passing it via xcode project- or target-settings. All syntax-possibilities coming to my mind either lead into xcode thinking its another linker flag instead of a parameter to the previous one, or the linker is throwing syntax related errors or the flag simply does nothing at all in comparison to not being set. I also opened the .pbxproj-file in a text-editor to edit it to the correct command line syntax manually, but when reloading the project with xcode, it auto changes the syntax into interpreting the parameter to force_load as a separate flag. Anyone having an idea on this issue? Thx, Kaiserludi.

• Weak hashmap with weak references to the values?

  - by Razor Storm

  I am building an android app where each entity has a bitmap that represents its sprite. However, each entity can be be duplicated (there might be 3 copies of entity asdf for example). One approach is to load all the sprites upfront, and then put the correct sprite in the constructors of the entities. However, I want to decode the bitmaps lazily, so that the constructors of the entities will decode the bitmaps. The only problem with this is that duplicated entities will load the same bitmap twice, using 2x the memory (Or n times if the entity is created n times). To fix this, I built a SingularBitmapFactory that will store a decoded Bitmap into a hash, and if the same bitmap is asked for again, will simply return the previously hashed one instead of building a new one. Problem with this, though, is that the factory holds a copy of all bitmaps, and so won't ever get garbage collected. What's the best way to switch the hashmap to one with weakly referenced values? In otherwords, I want a structure where the values won't be GC'd if any other object holds a reference to it, but as long as no other objects refers it, then it can be GC'd.

• jQuery carousel clicks update <select> list's "selected" option to match clicked item's title attrib

  - by Scott B

  The code below allows me to change a preview image outside the carousel widget so that it matches the element under the mouse. For example, if the user mouses over image2's thumbnail, the script updates .selectedImage so that it displays image2's full size version. I'd like to enhance it so that the #myThumbs options listing updates its "selected" option to match the carousel image that receives a click. Mouseover changes the preview image and click changes the select list to match the same name. The items in the carousel will have the same title attribute as the items in the select list, so I would expect that I can pass that value from the carousel to the select list. $(function() { $("#carousel").jCarouselLite({ btnNext: ".next", btnPrev: ".prev", visible: 6, mouseWheel: true, speed: 700 }); $('#carousel').show(); $('#carousel ul li').hover(function(e) { var img_src = $(this).children('img').attr('src'); $('.selectedImage img').attr('src',img_src); } ,function() { $('.selectedImage img').attr('src', '<?php echo $selectedThumb; ?>');}); }); <select id="myThumbs"> <option>image1</option> <option selected="selected">image2</option> <option>image3</option> </select>

• Pros and Cons of using SqlCommand Prepare in C#?

  - by MadBoy

  When i was reading books to learn C# (might be some old Visual Studio 2005 books) I've encountered advice to always use SqlCommand.Prepare everytime I execute SQL call (whether its' a SELECT/UPDATE or INSERT on SQL SERVER 2005/2008) and I pass parameters to it. But is it really so? Should it be done every time? Or just sometimes? Does it matter whether it's one parameter being passed or five or twenty? What boost should it give if any? Would it be noticeable at all (I've been using SqlCommand.Prepare here and skipped it there and never had any problems or noticeable differences). For the sake of the question this is my usual code that I use, but this is more of a general question. public static decimal pobierzBenchmarkKolejny(string varPortfelID, DateTime data, decimal varBenchmarkPoprzedni, decimal varStopaOdniesienia) { const string preparedCommand = @"SELECT [dbo].[ufn_BenchmarkKolejny](@varPortfelID, @data, @varBenchmarkPoprzedni, @varStopaOdniesienia) AS 'Benchmark'"; using (var varConnection = Locale.sqlConnectOneTime(Locale.sqlDataConnectionDetailsDZP)) //if (varConnection != null) { using (var sqlQuery = new SqlCommand(preparedCommand, varConnection)) { sqlQuery.Prepare(); sqlQuery.Parameters.AddWithValue("@varPortfelID", varPortfelID); sqlQuery.Parameters.AddWithValue("@varStopaOdniesienia", varStopaOdniesienia); sqlQuery.Parameters.AddWithValue("@data", data); sqlQuery.Parameters.AddWithValue("@varBenchmarkPoprzedni", varBenchmarkPoprzedni); using (var sqlQueryResult = sqlQuery.ExecuteReader()) if (sqlQueryResult != null) { while (sqlQueryResult.Read()) { //sqlQueryResult["Benchmark"]; } } } }

• Zend Form - how do I create these custom form elements?

  - by Jeremy Hicks

  This is a very specific instance where I'm having difficulty getting Zend Form to produce the correct output and supply the correct validation. I may have to go create a composite element but thought I'd ask here first. Here is the HTML I'm trying to get Zend Form to produce. I'd like this to be able to work where if the validation doesn't pass that the error messages still show up inline with the field that produced the error. <tr> <td>Budget</td> <td> <input type="radio" name="budget" value="unlimited" /> unlimited <br /> <input type="radio" name="budget" value="limited" /> $ <input type="text" name="budget_amount" /> every <select name="budget_period"> <option value="day">day</option> <option value="week">week</option> <option value="month">month</option> <option value="year">year</option> </select> </td> </tr> <tr> <td></td> <td><input type="checkbox" name="include_weekends" value="yes" /> include weekends?</td> </tr> The user can choose either unlimited or limited for the budget value, however, if they choose limited, then they are required to enter a value for the budget amount field and choose a value from the select for the budget period field.

• How to vertically align text in a button with a background drawable?

  - by neutrino

  I had a simple button set up with a background image defined like android:background="?attr/button" where ?attr/button was a reference to a simple 9-patch png. Everything worked fine, text in the button was aligned correctly. Then I needed to have a different background for a pressed state of the button. So I changed that to android:background="@drawable/state_button" where @drawable/state_button is an xml with the following states <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/button_pressed" /> <!-- pressed --> <item android:state_focused="true" android:drawable="@drawable/button_pressed" /> <!-- focused --> <item android:drawable="@drawable/button" /> <!-- default --> </selector> And after that I can't align the text properly. If I put android:gravity="center_vertical" the text is drawn about 1/4 of the button height from the top. I double-checked my 9-patch images, everything seems fine with them. And I also tried having regular pngs for the background, it also doesn't change anything.

• Linker error: wants C++ virtual base class destructor

  - by jdmuys

  Hi, I have a link error where the linker complains that my concrete class's destructor is calling its abstract superclass destructor, the code of which is missing. This is using GCC 4.2 on Mac OS X from XCode. I saw http://stackoverflow.com/questions/307352/g-undefined-reference-to-typeinfo but it's not quite the same thing. Here is the linker error message: Undefined symbols: "ConnectionPool::~ConnectionPool()", referenced from: AlwaysConnectedConnectionZPool::~AlwaysConnectedConnectionZPool()in RKConnector.o ld: symbol(s) not found collect2: ld returned 1 exit status Here is the abstract base class declaration: class ConnectionPool { public: static ConnectionPool* newPool(std::string h, short p, std::string u, std::string pw, std::string b); virtual ~ConnectionPool() =0; virtual int keepAlive() =0; virtual int disconnect() =0; virtual sql::Connection * getConnection(char *compression_scheme = NULL) =0; virtual void releaseConnection(sql::Connection * theConnection) =0; }; Here is the concrete class declaration: class AlwaysConnectedConnectionZPool: public ConnectionPool { protected: <snip data members> public: AlwaysConnectedConnectionZPool(std::string h, short p, std::string u, std::string pw, std::string b); virtual ~AlwaysConnectedConnectionZPool(); virtual int keepAlive(); // will make sure the connection doesn't time out. Call regularly virtual int disconnect(); // disconnects/destroys all connections. virtual sql::Connection * getConnection(char *compression_scheme = NULL); virtual void releaseConnection(sql::Connection * theConnection); }; Needless to say, all those members are implemented. Here is the destructor: AlwaysConnectedConnectionZPool::~AlwaysConnectedConnectionZPool() { printf("AlwaysConnectedConnectionZPool destructor call"); // nothing to destruct in fact } and also maybe the factory routine: ConnectionPool* ConnectionPool::newPool(std::string h, short p, std::string u, std::string pw, std::string b) { return new AlwaysConnectedConnectionZPool(h, p, u, pw, b); } I can fix this by artificially making my abstract base class concrete. But I'd rather do something better. Any idea? Thanks

• Creation of Objects: Constructors or Static Factory Methods

  - by Rachel

  I am going through Effective Java and some of my things which I consider as standard are not suggested by the book, for instance creation of object, I was under the impression that constructors are the best way of doing it and books says we should make use of static factory methods, I am not able to few some advantages and so disadvantages and so am asking this question, here are the benefits of using it. Advantages: One advantage of static factory methods is that, unlike constructors, they have names. A second advantage of static factory methods is that, unlike constructors, they are not required to create a new object each time they’re invoked. A third advantage of static factory methods is that, unlike constructors, they can return an object of any subtype of their return type. A fourth advantage of static factory methods is that they reduce the verbosity of creating parameterized type instances. I am not able to understand this advantage and would appreciate if someone can explain this point Disadvantages: The main disadvantage of providing only static factory methods is that classes without public or protected constructors cannot be subclassed. A second disadvantage of static factory methods is that they are not readily distinguishable from other static methods.I am not getting this point and so would really appreciate some explanation. Reference: Effective Java, Joshua Bloch, Edition 2, pg: 5-10 Also, How to decide to use whether to go for Constructor or Static Factory Method for Object Creation ?

• C++ operator lookup rules / Koenig lookup

  - by John Bartholomew

  While writing a test suite, I needed to provide an implementation of operator<<(std::ostream&... for Boost unit test to use. This worked: namespace theseus { namespace core { std::ostream& operator<<(std::ostream& ss, const PixelRGB& p) { return (ss << "PixelRGB(" << (int)p.r << "," << (int)p.g << "," << (int)p.b << ")"); } }} This didn't: std::ostream& operator<<(std::ostream& ss, const theseus::core::PixelRGB& p) { return (ss << "PixelRGB(" << (int)p.r << "," << (int)p.g << "," << (int)p.b << ")"); } Apparently, the second wasn't included in the candidate matches when g++ tried to resolve the use of the operator. Why (what rule causes this)? The code calling operator<< is deep within the Boost unit test framework, but here's the test code: BOOST_AUTO_TEST_SUITE(core_image) BOOST_AUTO_TEST_CASE(test_output) { using namespace theseus::core; BOOST_TEST_MESSAGE(PixelRGB(5,5,5)); // only compiles with operator<< definition inside theseus::core std::cout << PixelRGB(5,5,5) << "\n"; // works with either definition BOOST_CHECK(true); // prevent no-assertion error } BOOST_AUTO_TEST_SUITE_END() For reference, I'm using g++ 4.4 (though for the moment I'm assuming this behaviour is standards-conformant).

• python gui generate math equation

  - by Nero Dietrich

  I have a homework question for one specific item with python GUIs. My goal is to create a GUI that asks a random mathematical equation and if the equation is evaluated correctly, then I will receive a message stating that it is correct. My main problem is finding out where to place my statements so that they show up in the labels; I have 1 textbox which generates the random equation, the next textbox is blank for me to enter the solution, and then an "Enter" button at the end to evaluate my solution. It looks like this: [randomly generated equation][Empty space to enter solution] [ENTER] I've managed to get the layout and the evaluate parameters, but I don't know where to go from here. This is my code so far: class Equation(Frame): def __init__(self,parent=None): Frame.__init__(self, parent) self.pack() Equation.make_widgets(self) Equation.new_problem(self) def make_widgets(self): Label(self).grid(row=0, column=1) ent = Entry(self) ent.grid(row=0, column=1) Label(self).grid(row=0, column=2) ent = Entry(self) ent.grid(row=0, column=2) Button(self, text='Enter', command=self.evaluate).grid(row=0, column=3) def new_problem(self): pass def evaluate(self): result = eval(self.get()) self.delete(0, END) self.insert(END, result) print('Correct')

I want to put them into a structure where I can reference them like this: youtube[0][repeated] = 3; youtube[0][download] = "http://www.youtube.com/get_video?video_id=dw1Vh9Yzryo&fmt=36" youtube[1][repeated] = 3; youtube[1][download] = "http://www.youtube.com/get_video?video_id=bOF3o8B292U&fmt=36" youtube[2][repeated] = 3; youtube[2][download] = "http://www.youtube.com/get_video?video_id=yAY4vNJd7A8&fmt=36" "This video was repeated " + youtube[0][repeated] + " times and you can download it here: " + youtube[0][download]; How can I set this multidimensional array up? Been Googling for hours and I don't know how to set it up. Can anyone help me out?

• MVC View Model Intellesense / Compile error

  - by Marty Trenouth

  I have one Library with my ORM and am working with a MVC Application. I have a problem where the pages won't compile because the Views can't see the Model's properties (which are inherited from lower level base classes). They system throws a compile error saying that 'object' does not contain a definition for 'ID' and no extension method 'ID' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) implying that the View is not seeing the model. In the Controller I have full access to the Model and have check the Inherits from portion of the view to validate the correct type is being passed. Controller: return View(new TeraViral_Blog()); View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<com.models.TeraViral_Blog>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Index2 </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Index2</h2> <fieldset> <legend>Fields</legend> <p> ID: <%= Html.Encode(Model.ID) %> </p> </fieldset> </asp:Content>

• Issues with intellisense, references, and builds in Visual Studio 2008

  - by goober

  Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give!

• How do i make divs go into another row when full?

  - by acidzombie24

  My code is something like the below. When theres 3 images everything is fine once theres 4 it gets full and moves the entire div.top into another row. How do i make the div inside top just start a new row instead? I tried writing .top width=500px but once it hits or passes it instead the images inside are squeeze together instead of each being 150x150. I tried max-width on top instead and in opera and chrome i see the border of top as 500width but the images continue to render pass it. (i have a firefox problem with my div so the width looks fixed to something else). So how do i make these divs go into another row? and not try to squeeze together <div class="top"> <div><a href><img/></a></div> <div><a href><img/></a></div> <div><a href><img/></a></div> </div>

• Stop an executing recursive javascript function

  - by DA

  Using jQuery, I've build an image/slide rotator. The basic setup is (in pseudocode): function setupUpSlide(SlideToStartWith){ var thisSlide = SlideToStartWith; ...set things up... fadeInSlide(thisSlide) } function fadeInSlide(thisSlide){ ...fade in this slide... fadeOutSlide(thisSlide) } function fadeOutSlide(thisSlide){ ...fade out this slide... setupUpSlide(nextSlide) } I call the first function and pass in a particular slide index, and then it does its thing calling chain of functions which then, in turn, calls the first function again passing in the next index. This then repeats infinitely (resetting the index when it gets to the last item). This works just fine. What I want to do now is allow someone to over-ride the slide show by being able to click on a particular slide number. Therefore, if slide #8 is showing and I click #3, I want the recursion to stop and then call the initial function passing in slide #3, which then, in turn, will start the process again. But I'm not sure how to go about that. How does one properly 'break' a recursive script. Should I create some sort of global 'watch' variable that if at any time is 'true' will return: false and allow the new function to execute?
