• How to check a bool setting in my iphone app

  - by dusk

  I have a setting in Root.plist with Key = 'latestNews' of type PSToggleSwitchSpecifier and DefaultValue as a boolean that is checked. If I understand that correctly, it should = YES when I pull it in to my code. I'm trying to check that value and set an int var to pass it to my php script. What is happening is that my boolean is either nil or NO and then my int var = 0. What am I doing wrong? int latestFlag; NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults]; BOOL latestNews = [prefs boolForKey:@"latestNews"]; if (latestNews) latestFlag = 1; else latestFlag = 0; NSString *urlstr = [[NSString alloc] initWithFormat:@"http://www.mysite.com/folder/iphone-test.php?latest=%d", latestFlag]; NSURL *url = [[NSURL alloc] initWithString:urlstr]; //these are auto-released NSString *ans = [NSString stringWithContentsOfURL:url]; NSArray *listItems = [ans componentsSeparatedByString:@","]; self.listData = listItems; [urlstr release]; [url release];

• Passing Extras and screen rotation

  - by Luis A. Florit

  This kind of questions appear periodically. Sorry if this has been covered before, but I'm a newbie and couldn't find the appropriate answer. It deals with the correct implementation of communication between classes and activities. I made a gallery app. It has 3 main activities: the Main one, to search for filenames using a pattern; a Thumb one, that shows all the images that matched the pattern as thumbnails in a gridview, and a Photo activity, that opens a full sized image when you click a thumb in Thumbs. I pass to the Photo activity via an Intent the filenames (an array), and the position (an int) of the clicked thumb in the gridview. This third Photo activity has only one view on it: a TouchImageView, that I adapted for previous/next switching and zooming according to where you shortclick on the image (left, right or middle). Moreover, I added a longclick listener to Photo to show EXIF info. The thing is working, but I am not happy with the implementation... Some things are not right. One of the problems I am experiencing is that, if I click on the right of the image to see the next in the Photo activity, it switches fine (position++), but when rotating the device the original one at position appears. What is happening is that Photo is destroyed when rotating the image, and for some reason it restarts again, without obeying super.onCreate(savedInstanceState), loading again the Extras (the position only changed in Photo, not on the parent activities). I tried with startActivityForResult instead of startActivity, but failed... Of course I can do something contrived to save the position data, but there should be something "conceptual" that I am not understanding about how activities work, and I want to do this right. Can someone please explain me what I am doing wrong, which is the best method to implement what I want, and why? Thanks a lot!!!

• How to Object Array to List

  - by Peter Black

  (C#) I have 2 classes. 1 is called Employee. The other is my "main". I am trying to take a list and assign each value in list to an array of Employee object. //Inside "Main" class int counter = NameList.Count; Employee[] employee = new Employee[counter]; for (int i = 0; i <= counter; i++) { employee[i].Name = NameList[i]; employee[i].EmpNumber = EmpNumList[i]; employee[i].DateOfHire = DOHList[i]; employee[i].Salary = SalaryList[i]; employee[i].JobDescription = JobDescList[i]; employee[i].Department = DeptList[i]; } This returns the error: An unhandled exception of type 'System.NullReferenceException' occurred in Pgm4.exe Additional information: Object reference not set to an instance of an object. I think this means that I am not calling the list properly. Any help would be much appreciated. Thank you.

• Transfering a set with a Wildcarded Generic to a List in Java

  - by Daniel Bingham

  I have a data type that contains a set and a method that expects List<? extends MyClass>. The data type has Set<? extends MyClass>. I need to be able to move the stuff out of the set and into the List. The order it goes into the list doesn't matter, it just needs to start keeping track of it so that it can be reordered when displayed. Suffice to say that changing the Set into a List in the data type is out of the question here. This seems pretty easy at first. Create a new method that takes a Set instead of a List, changes it into a list and then passes it on to the old method that just took a list. The problem comes in changing the set to a list. public void setData(Set<? extends MyClass> data) { List<? extends Myclass> newData = ArrayList< /* What goes here? */ >(); for(ConcordaEntityBean o : data) { newData.add(o); } setData(newData); } Obviously, I can't instantiate an ArrayList with a wildcard, it chokes. I don't know the type at that point. Is there some way to pull the type out of data and pass it to ArrayList? Can I just instantiate it with MyClass? Is there some other way to do this?

• How to access widgets created within functions in later function calls in Qt

  - by Inanepenguin

  So currently I have code, in C++, that creates a few QLabels, a QLineEdit, and a QCheckBox when a selection is made from a QComboBox. However, I would like to be able to access the widgets I have created in a later function to destroy them if a new selection is made from the combo box. I am able to access the objects created from using the Designer by doing ui-Object but i am not able to do that with objects created by using my own code. Can I do that some how, because I know how to work with that. In short, I would like to be able to dynamically create/destroy QWidgets based on selections made by the user. Is there a reference I should know of to do this, or any documentation? Or am I just completely going about this the wrong way? Here is the code I presently have for creating the objects: if (eventType == QString::fromStdString("Birthday")) { QLabel *label1 = new QLabel ("Celebrant: "); QLabel *label2 = new QLabel ("Surprise: "); QLineEdit *lineEdit = new QLineEdit; QCheckBox *box = new QCheckBox; ui->gridLayout->addWidget(label1,3,0,1,1, 0); ui->gridLayout->addWidget(label2,4,0,1,1,0); ui->gridLayout->addWidget(lineEdit,3,1,1,1,0); ui->gridLayout->addWidget(box,4,1,1,2,0); }

• Will this web service accept both raw xml and an object?

  - by ChadNC

  We have a web service that provides auto insurance quotes and a company that provides an insurance agency management system would like to use the web service for thier client but they want to pass the web service raw xml instead of using the wsdl to create a port, the object the service expects and calling the web method. The web service has performed flawlessly by creating an object like so com.insurance.quotesvc.AgencyQuote service = new com.insurance.quotesvc.AgencyQuote(); com.insurance.quotesvc.QuotePortType port = service.getQuotePortType(); com.insurance.quotesvc.schemas.request.ACORD parameter = null; Then create initialize the request object with the other objects that make up the response. parameter = factory.createACORD(); parameter.setSignonRq(signOn); parameter.setInsurancesSvcRq(svcRq); And send the request to the web service. com.insurance.quotesvc.schemas.response.ACORD result = null; result = port.requestQuote(parameter); By doing that I am able to easily marshall the request and the result into an xml file and do with them as I wish. So if a client was to send the web service via an http post as raw xml inside of a soap envelope. Would the web service be able to handle the xml without any changes being made to the web service or would there need to be changes made to the web service in order for it to handle a request of that type? The web service is a JAX_WS and we currently have both Java and C# clients consuming the web service using the method described above but now there is another client who wants to send raw xml inside of a soap envelope instead of creating the objects. I feel pretty sure that they will be making the call to the web service using vb. I'm sure I'm missing something obvious but it is eluding me at the moment and any help is greatly appreciated.

• Why wouldn't an embedded silverlight control work in a page?

  - by rsteckly

  Hi, I have a silverlight application project in my solution. The other project is a web application project that has a .xap file in ClientBin. When I created the silverlight project, it asked if I wanted the asp.net application to host it (and I said yes). In the root directory, there is a test page for the silverlight control. That loads the control. In another directory, I insert the SAME asp markup to get the silverlight control to launch again. Nothing happens. Why would the silverlight launch on one page and not on the other? Can people help point me to documentation about dependencies that I might not know about? I've put a reference to Silverlight.js on the page as well. Here's the markup: <div id="silverlightControlHost"> <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="../ClientBin/Editor.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="3.0.40818.0" /> <param name="autoUpgrade" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40818.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div> </div>

• Linq - reuse expression on child property

  - by user175528

  Not sure if what I am trying is possible or not, but I'd like to reuse a linq expression on an objects parent property. With the given classes: class Parent { int Id { get; set; } IList<Child> Children { get; set; } string Name { get; set; } } class Child{ int Id { get; set; } Parent Dad { get; set; } string Name { get; set; } } If i then have a helper Expression<Func<Parent,bool> ParentQuery() { Expression<Func<Parent,bool> q = p => p.Name=="foo"; } I then want to use this when querying data out for a child, along the lines of: using(var context=new Entities.Context) { var data=context.Child.Where(c => c.Name=="bar" && c.Dad.Where(ParentQuery)); } I know I can do that on child collections: using(var context=new Entities.Context) { var data=context.Parent.Where(p => p.Name=="foo" && p.Childen.Where(childQuery)); } but cant see any way to do this on a property that isnt a collection. This is just a simplified example, actually the ParentQuery will be more complex and I want to avoid having this repeated in multiple places as rather than just having 2 layers I'll have closer to 5 or 6, but all of them will need to reference the parent query to ensure security.

• Node.js/Express Partials problem: Can't be nested too deep?

  - by heorling

  I'm learning Node.js, Express, haml.js and liking it. I've run into a prety annoying problem though. I'm pretty new to this but have been getting nice results so far. I'm writing a jquery heavy web app that relies on a table containing divs. The divs slide around, switch back and fourth and are resized etc to my hearts content. What I'm looking for a way to switch (template?) the divs. Since I've been building in express and mimicking the chat example it would make sense to use partials. The rub is that I've been using inexplicit divs in haml, held within a td. The divs are cunstructed as follows: %tr %td .class1.class2.class3.classetc Which has worked fine cross browser. Parsing the classes works great for the js code to pass arguments around, fetch values etc. What I'd like to be able to do is something like: %tr %td .class1.class2.class3.classetc %ul#messages != this.partial('message.html.haml', { collection: messages }) Any combination I've tried with this has failed however. And I might have tried them all. If I could put a partial into that div I'd probably be set. And you can nest them as long as you use #ids instead of .classes. But if you use more than one class it breaks! I think that's the most accurate way of summing it up. How do you do this? I've checked out various templating solutions like mu.js and micro template like by John Resig. I earlier checked out this thread on templating engines. It's very possible I'm making some fundamental mistake here, I'm new to this. What's a good way to do this?

• How do you use boost iterators

  - by Neil G

  It worked, and then I added the typedefs so that I could have a const_sparse_iterator as well.

• jQuery.data() works in Mac OS WebKit, but not on iPhone OS?

  - by rpj

  I'm playing around with jQTouch for an iPhone OS app that I've been toying with off and on for a while. I wanted to try my hand building it as a web app so I started playing with jQTouch. For reference, here is the page+source (all my code is currently in index.html so you can just "View Source" to see it all): http://rpj.me/doughapp.com/wd/ Essentially, I'm trying to save pertinent JSON objects retrieved from Google Local into DOM objects using the data() method (in this example, obj is the Google Local object): $('#locPane').data('selected', obj); then later (in a different "pane"), retrieving that object to be used: $('#locPane').bind('pageAnimationEnd', function(e, inf) { var selobj = $(this).data('selected'); // use 'selobj' here ... } In Chromium and Safari on the desktop OS (Snow Leopard in my case), this works perfectly (try it out). However, the same code returns undefined for the call to $(this).data('selected') in the second snippet above. I've also tried $('#' + e.target.id).data('selected') and even the naive $('#locPane').data('selected'). All variants return undefined in the iPhone OS version of WebKit, but not on the desktop. Interestingly, the running this on Mobile Safari in the iPhone Simulator fails as well. If you look at the full source, you'll see that I even try to save this object into my global jQTouch object (named jqt in my code). This, too, fails on the mobile platform. Has anyone else ever ran into this? I'll admit to not being a web/javascript programmer by trade, so if I'm making an idiot's error please call me out on it. Thank you in advance for the help! -RPJ Update: I didn't make it clear in the original post, but I'm open to any workaround if it works consistently. Since I'm having trouble storing these objects in general, anything that allows me to keep them around is good enough for now. Thanks!

• Creating object/array to method in request based on __gettypes in PHP

  - by LochNess

  I'm having trouble with the array or object that should be passed based on the response from __gettypes. The __gettypes response: [0] => struct CDataWrapper { schema;any; } [1] => struct NewMember { MemberDetail MemberDetails;ArrayOfHobby Hobbies; } [2] => struct MemberDetail { string Name; string Age; string Sex; } [3] => struct ArrayOfHobby { Hobby Hobby; } [4] => struct Hobby { string Name; string HoursUsedOnHobbyWeekly;boolean Favourite; } ... etc. The methods are: [0] => ReceiveMemberResponse ReceiveMember(ReceiveMember $parameters) [1] => ReturnMemberResponse ReturnMember(ReturnMember $parameters) So far I have this PHP: $client = new SoapClient('http://domain.com?wsdl'); class MemberDetail { public $Name = ''; public $Age = ''; public $Sex = ''; } $mc = new MemberDetail(); $mc->Name= 'Bob'; $mc->Age= '14'; $mc->Sex= 'Male'; $myParam = array('ReceiveMember'=>$mc); $wcf = $client->ReceiveMember($myParam); $wcfResult = $wcf->ReturnMember; print_r($wcfResult) when i call the page it returns: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. I'm not really sure how to create the array or object to pass on as $myParam since im no expert with PHP either.

• StructureMap Configuration Per Thread/Request for the Full Dependency Chain

  - by Phil Sandler

  I've been using Structuremap for a few months now, and it has worked great on some smaller (green field) projects. Most of the configurations I have had to set up involve a single implementation per interface. In the cases where I needed to choose a specific implementation at runtime, I created a factory class that used ObjectFactory.GetNamedInstance<(). In the smaller projects, there were few enough of these cases where I was comfortable with the references to ObjectFactory. My understanding is that you want to limit these references as much as possible, and ideally only reference the ObjectFactory once. I am working to refactor a larger codebase to use IOC/StructureMap, and am finding that I may need many of these factory classes with ObjectFactory references to get what I need. Essentially, I am creating a "root service" with the ObjectFactory, so that everything in the dependency chain is managed by the container. The root service is created by name (i.e. "BuildCar", "BuildTruck"), and the services needed deeper in the dependency chain could also be constructed using the same name--so the "IAttachWheels" service could vary based on whether a car or truck is being built. Since the class that depends on IAttachWheels is the same in both configurations, I don't think I can use ConstructedBy in the registry to choose the implementation. Also, to be clear, the IAttachWheels implementations need to be managed by the container as well, because the dependency chain runs fairly deep. I looked briefly at Profiles as an option, but read (here on StackOverflow) that changing profiles essentially changes implementations for all threads. Is there a feature that is similar to profiles that is thread/request specific? Is the factory class that references ObjectFactory approach the right way to go? Any thoughts would be appreciated.

• How to change image on locale base in magento?

  - by Nil

  I want to change search image in magento. On search in magento the image name is btn_search.gif. Right now it take image from skin/frontend/default/default/images. And the file is /app/design/frontend/default/default/template/catalogsearch/form.mini.phtml where mention this tag as <input id="search-button" type="image" src="<?php echo $this->getSkinUrl('images/btn_search.gif') ?>" alt="<?php echo $this->__('Search') ?>" /> I check the code and i found that we can pass locale as _type in this as <input id="search-button" type="image" src="<?php echo $this->getSkinUrl('images/btn_search.gif', array('_type'=>'local')) ?>" alt="<?php echo $this->__('Search') ?>" /> But when i check the code this will just check in locale directory that this file exist in that locale or not. If this exist then it will take skin image. I want to use that locale image instead of that skin image. So when i click on french store i get the image which is i set in /app/design/frontend/default/default/locale/fr_FR/images/btn_search.gif I check the code for getSkinUrl in /app/code/core/Mage/Core/Model/Design/Package.php. And i found that he check locale for file but it return skin url. Is there any method which return locale url ?

• Handling row selection from a simple grid using jquery and asp.net mvc

  - by Jonn

  Using a simple table and jquery, how would you manually handle selection using jquery? So far, I've managed to add a gridrowselected class on the tr when the click event is called so that I'll know which row is currently selected. But I don't know how to pass the selected data back to the controller (or at least an index I placed on the row). I tried something like this $(function() { $('#ProjectList .gridrow').click(function() { // Get row's index var projectId = $(this).find('input[name$=ProjectId]').val(); // Remove the input if it already exists var parentForm = $(this).parents('form'); parentForm.remove('input[name="selectedRows"][value="' + projectId + '"]'); // If it is selected, create the form. If it's not selected then the input just gets removed (the user must have clicked on it and deselected the row) if ($(this).hasClass('gridrow-selected') === true) { parentForm.append($('<input>', { type: "hidden", name: "selectedRows", value: projectId })); } }); }); which I'm expecting to create a hidden input so that when I post, selectedRows gets passed onto the controller. But all it does is create the input, but the data still doesn't get passed to the controller.

• IIS 6.0 Rewrite rules for Wordpress (Forward slash not working and other things)

  - by DigitalBlade

  Hi, I am using Wordpress 3.0.4 on IIS 6.0 and Windows Server 2003, hosted by a company. I was having lots of issues using permalinks. I have fixed most, but now I have an issue with a forward-slash not being added to the address. This would be fine on most websites, but not on IIS for some reason. Specifically, if I go to "mysite.com/wp-admin" I can log-in and get to the dashboard, but as soon as I click anything there i am redirected to a broken link. For example: "mysite.com/post-new.php". If I add the slash at the end it's fine. So I tried to have a rewrite rule to automatically add the slash to such address: RewriteRule /wp-admin /wp-admin/ [L] But it still doesn't work. For your reference, here's the complete file: [ISAPI_Rewrite] RewriteBase / RewriteCond ${REQUEST_FILENAME} !-f RewriteCond ${REQUEST_FILENAME} !-d # For special WordPress folders (e.g. theme, admin, etc.) RewriteRule /wp-admin /wp-admin/ [L] RewriteRule /wp-(.*) /wp-$1 [L] RewriteRule /(.*\.(?:jpg|jpeg|gif|css|txt|xml|html|png|js)) /$1 [I,L] # Rules to ensure that normal content gets through RewriteRule /images/(.*) /images/$1 [L] RewriteRule /favicon.ico /favicon.ico [L] RewriteRule /robots.txt /robots.txt [L] RewriteRule /phpmyadmin/(.*) /phpmyadmin/$1 [L] RewriteRule /phpmyadmin /phpmyadmin/ [L] # For all WordPress pages RewriteRule ^/$ /index.php [L] RewriteRule /(.*) /index.php/$1 [L] Any ideas?

• UIDocumentInteractionController & ARC: [UIPopoverController dealloc] reached while popover is still visible

  - by muffel

  This issue or similar issues have been discussed here before, but I didn't find any working solution for me. I am using the following code to display a UIDocumentInteractionController on an ARC-enabled iOS 7 project: - (void) exportDoc{ // [...] docController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:path]]; docController.delegate = self; [docController presentOpenInMenuFromBarButtonItem:mainMenuButton animated:YES]; } First I didn't want to create a property that holds the controller reference, but as many people said that there are not alternatives to it. It is defined as @property (strong) UIDocumentInteractionController* docController; exportDoc is run in the main thread using NSOperationQueue. Whenever it is executed, I get the following error message: Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.' This is what the backtrace says: (lldb) bt * thread #1: tid = 0x1c97d9, 0x000000019a23c1c0 libobjc.A.dylibobjc_exception_throw, queue = 'com.apple.main-thread', stop reason = breakpoint 2.1 frame #0: 0x000000019a23c1c0 libobjc.A.dylibobjc_exception_throw frame #1: 0x000000018d982e90 CoreFoundation+[NSException raise:format:] + 128 frame #2: 0x0000000190bc348c UIKit-[UIPopoverController dealloc] + 96 frame #3: 0x0000000190e18fc8 UIKit-[UIDocumentInteractionController dealloc] + 168 frame #4: 0x000000019a255474 libobjc.A.dylib(anonymous namespace)::AutoreleasePoolPage::pop(void*) + 524 frame #5: 0x000000018d881988 CoreFoundation_CFAutoreleasePoolPop + 28 frame #6: 0x000000018e42cb18 Foundation-[NSOperationInternal _start:] + 892 frame #7: 0x000000018e4eea38 Foundation__NSOQSchedule_f + 76 frame #8: 0x000000019a813fd4 libdispatch.dylib_dispatch_client_callout + 16 frame #9: 0x000000019a8171dc libdispatch.dylib_dispatch_main_queue_callback_4CF + 336 frame #10: 0x000000018d942c2c CoreFoundation__CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE + 12 frame #11: 0x000000018d940f6c CoreFoundation__CFRunLoopRun + 1452 frame #12: 0x000000018d881c20 CoreFoundationCFRunLoopRunSpecific + 452 frame #13: 0x0000000193511c0c GraphicsServicesGSEventRunModal + 168 frame #14: 0x00000001909b2fdc UIKitUIApplicationMain + 1156 * frame #15: 0x000000010000947c MyApplicationmain(argc=1, argv=0x000000016fdfbc80) + 108 at main.m:16 frame #16: 0x000000019a82faa0 libdyld.dylibstart + 4 As far as I understand the autoreleasepool just releases the controller.

• How can I bind multiple Jquery UI Slider with "year" Select?

  - by arthur_br

  Hi, I'm trying to render sliders instead of select components. Each page has several select components marked with class='jqselect' and all of them will have decreasing year values (some years may be missing). Eg. a select may have values [2010, 2009, 2006, 2005, 2004]. I have tried binding it both following the examples in the jQuery UI doc (but ignoring the missing years) and using selectToUISlider by filamentgroup (http://www.filamentgroup.com/lab/update_jquery_ui_slider_from_a_select_element_now_with_aria_support//). None of them work. Here is what I've done so far: Binding selects with following slider container divs: $('#content div.jqslider').slider({ animate: true, min: $(this).prev().children().last().val(), max: $(this).prev().children().first().val(), slide: function(event, ui) { var select = $(this).prev(); select.val($(this).slider('option', 'value')); console.log($(this).slider('option', 'value')); //debug } }); This renders the slider, but console logs values from 0 to 100 and selects obviously does not change with the event. Using selectToUISlider: $('#content select.jqselect').selectToUISlider(); This does not even render the slider, throwing an error 'b is undefined' in jquery-min.js (line 30, v1.4.2). If I pass the identifier of only one of the sliders, it is rendered but very buggy. Please, I'm stucked in the by two days and any help is much appreciated. Regards, Arthur

  I have a Web Site project, and within it I have a user Web Control defined in an ascx file. The control is added to the Site.Master, and it shows up correctly on the page and everything is fine. I need to override some of the control's fields on one of the pages that derive from Site.Master. // In OnLoad: MyControlName control = (MyControlName) Page.Master.GetBaseMasterPage().FindControl("controlID")); The issue is that MyControlName doesn't register as a valid Type on the child page. If I add a second instance of the control to the child page directly, the above works as needed, but if the control isn't placed directly on the page, and instead is only defined in the master page, the type is undefined. The control is not in a namespace, and is defined within the project, so I don't know why it is having such an issue location the appropriate type. If I put a breakpoint in the OnLoad, the type listed for the control is ASP.my_control_name_ascx, but using that does not work either. Why can't the child class reference the correct type? Can I fix this? Thanks!

• ASP.NET MVC4: How do I keep from having multiple identical results in my lookup tables

  - by sehummel

  I'm new to ASP.NET so this may be an easy question. I'm seeding my database with several rows of dummy data. Here is one of my rows: new Software { Title = "Microsoft Office", Version = "2012", SerialNumber = "12346231434543", Platform = "PC", Notes = "Macs really rock!", PurchaseDate = "2011-12-04", Suite = true, SubscriptionEndDate = null, SeatCount = 0, SoftwareTypes = new List<SoftwareType> { new SoftwareType { Type="Suite" }}, Locations = new List<Location> { new Location { LocationName = "Paradise" }}, Publishers = new List<SoftwarePublisher> { new SoftwarePublisher { Publisher = "Microsoft" }}} But when I do this, a new row is created for each location, with the LocationName being set in each row like this. We only have two locations. How do I get it to create a LocationID property for the Software class and in my Locations class. Here is my Location class: public class Location { public int Id { get; set; } [Required] [StringLength(20)] public string LocationName { get; set; } public virtual Software Software { get; set; } } I have this line in my Software class to reference this table: public virtual List<Location> Locations { get; set; } Again, what I want when I am done is a Locations table with two entries, and a LocationID field in my Software table. How do I do this?

• Best practice for managing changes to 3rd party open source libraries?

  - by Jeff Knecht

  On a recent project, I had to modify an open source library to address a functional deficiency. I followed the SVN best practice of creating a "vendor source" repository and made my changes there. I also submitted the patch to the mailing list of that project. Unfortunately, the project only has a couple of maintainers and they are very slow to commit updates. At some point, I expect the library to be updated, and I expect that my project will want to use the upgraded library. But now I have a potential problem... I don't know whether my patch will have been applied to this future release of the 3rd party library. I also don't know whether my patch will even still be compatible with the internal implementation of the upgraded components. And in all likelihood, someone else will be maintaining my project by that point. Should I name the library in a special way so it is clear that we made special modifications (eg. commons-lang-2.x-for-my-project.jar)? Should I just document the patch and reference the SVN location and a link to the mailing list item in a README? No option that I can think of seems to be fool-proof in an upgrade scenario. What is the best practice for this?

• Implementing Tagging System with PHP and mySQL. Caching help!!!

  - by Hamid Sarfraz

  With reference to this post: http://stackoverflow.com/questions/2122546/how-to-implement-tag-counting I have implemented the suggested 3 table tagging system completely. To count the number of Articles per tag, i am using another column named tagArticleCount in the tag definition table. (other columns are tagId, tagText, tagUrl, tagArticleCount). If i implement realtime editing of this table, so that whenever user adds another tag to article or deletes an existing tag, the tag_definition_table is updated to update the counter of the added/removed tag. This will cost an extra query each time any modification is made. (at the same time, related link entry for tag and article is deleted from tagLinkTable). An alternative to this is not allowing any real time editing to the counter, instead use CRONs to update counter of each tag after a specified time period. Here comes the problem that i want to discuss. This can be seen as caching the article count in database. Can you please help me find a way to present the articles in a list when a tag is explored and when the article counter for that tag is not up to date. For example: 1. Counter shows 50 articles, but there are infact 55 entries in the tag link table (that links tags and articles). 2. Counter shows 50 articles, but there are infact 45 extries in the tag link table. How to handle these 2 scenerios given in example. I am going to use APC to keep cache of these counters. Consider it too in your solution. Also discuss performance in the realtime / CRONNED counter updates.

• Why strings behave like ValueType

  - by AJP

  I was perplexed after executing this piece of code, where strings seems to behave as if they are value types. I am wondering whether the assignment operator is operating on values like equality operator for strings. Here is the piece of code I did to test this behavior. using System; namespace RefTypeDelimma { class Program { static void Main(string[] args) { string a1, a2; a1 = "ABC"; a2 = a1; //This should assign a1 reference to a2 a2 = "XYZ"; //I expect this should change the a1 value to "XYZ" Console.WriteLine("a1:" + a1 + ", a2:" + a2);//Outputs a1:ABC, a2:XYZ //Expected: a1:XYZ, a2:XYZ (as string being a ref type) Proc(a2); //Altering values of ref types inside a procedure //should reflect in the variable thats being passed into Console.WriteLine("a1: " + a1 + ", a2: " + a2); //Outputs a1:ABC, a2:XYZ //Expected: a1:NEW_VAL, a2:NEW_VAL (as string being a ref type) } static void Proc(string Val) { Val = "NEW_VAL"; } } } In the above code if I use a custom classes instead of strings, I am getting the expected behavior. I doubt is this something to do with the string immutability? welcoming expert views on this.

• How make this jquery function reusable?

  - by Pandiya Chendur

  Comsider this jquery function, function showresults(jsonobj) { $.each(jsonobj, function(i, employee) { divs += '<div class="resultsdiv"><br /><span style="display: inline-block;width:150px;" class="resultName">' + employee.Emp_Name + '</span><span class="resultfields" style="padding-left:100px;">Category&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Desig_Name + '</span><br /><br /><span id="SalaryBasis" class="resultfields">Salary Basis&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.SalaryBasis + '</span><span class="resultfields" style="padding-left:25px;">Salary&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.FixedSalary + '</span><span style="font-size:110%;font-weight:bolder;padding-left:25px;">Address&nbsp;:</span>&nbsp;<span class="resultfieldvalues">' + employee.Address + '</span></div>'; }); } Here i am iterating my json data and drawing div elements.... As you see these div elements are hardcoded how to pass these html div elements dynamically by a variable... var divs=<div></div> function showresults(jsonobj,divs) { $.each(jsonobj, function(i, employee) { divs += divs Is this correct way of doing but there will be an error employee object wont be there know when my divs variable declared outside the function... Any suggestion...
