• iphone bookmarklet cookie persistence

  - by Larry Davis

  I have an iphone (jqtouch based) web app that uses cookies for authentication. The use flow is as follows : user goes to the mobile landing page and is instructed to save the page as a bookmarklet on their home page. they launch the bookmarklet to go to a login page to login and get a cookie. the cookie works and they can navigate throughout the web site. However this session cookie is not persistent. If they leave safari and then restart using the saved bookmarklet, the cookies set during their previous session are gone. Just using safari (ie: launch safari directly rather than through the bookmarklet) to navigate the pages works fine (ie: start safari, go to url, do login, restart safari, go back to url). I find that that the cookies that were active when the bookmarklet was created are persistent but any cookies set during the session when safari is accessed through the bookmarklet are not persistent. I'm wondering if this is a safari/iphone issue and/or if there is any way around this. Many thanks for any insight you can provide.

• Auto-sizing and positioning in Flex

  - by Addsy

  I am working on a flex app that uses XML templates to dynamically create DisplayObjects. These templates define different layouts that can be used for each page of content in the app (ie , 2 columns, 3 columns etc etc). The administrator can select from one of these and populate each area with their content. The templates add one of 3 types of DisplayObject - HBox, VBox or a third component - LibraryContentContainer (an mxml component that is defined as part of the app) - which is effectively a canvas element with a TextArea inside. The problem that I am getting is that I need each of these areas to automatically resize to fit the length of the content but don't seem to be able to find an effective way to do so. In the LibraryContentContainer, when the value of the TextArea is set, I am calling .validateNow() on the LibraryContentContainer. I then set the height property on both the TextArea and LibraryContentContainer to match the textHeight property of the TextArea. In the following example, this is the LibraryContentContainer, viewer is the TextArea and the value property of the TextArea is bound to this.__Value. v is the variable containing the content for the textarea this.__Value = v; this.validateNow(); this.viewer.height = this.viewer.textHeight; this.height = this.viewer.height; This works to a degree in that the TextArea grows or shrinks depending on the length of content, but it's still not great - sometimes there are still vertical scrollbars even tho the size of the TextArea has grown. Anyone got any ideas? Thanks Adam

• .NET 4 RTM MetadataType attribute ignored when using Validator

  - by bart

  I am using VS 2010 RTM and trying to perform some basic validation on a simple type using MetadataTypeAttribute. When I put the validation attribute on the main class, everything works. However, when I put it on the metadata class, it seems to be ignored. I must be missing something trivial, but I've been stuck on this for a while now. I had a look at the Enterprise Library validation block as a workaround, but it doesn't support validation of single properties out of the box. Any ideas? class Program { static void Main(string[] args) { Stuff t = new Stuff(); try { Validator.ValidateProperty(t.X, new ValidationContext(t, null, null) { MemberName = "X" }); Console.WriteLine("Failed!"); } catch (ValidationException) { Console.WriteLine("Succeeded!"); } } } [MetadataType(typeof(StuffMetadata))] public class Stuff { //[Required] //works here public string X { get; set; } } public class StuffMetadata { [Required] //no effect here public string X { get; set; } }

• ASP.NET MVC: what mechanic returns ViewModel objects?

  - by Dr. Zim

  As I understand it, Domain Models are classes that only describe the data (aggregate roots). They are POCOs and do not reference outside libraries (nothing special). View models on the other hand are classes that contain domain model objects as well as all the interface specific objects like SelectList. A ViewModel includes using System.Web.Mvc;. A repository pulls data out of a database and feeds them to us through domain model objects. What mechanic or device creates the view model objects, populating them from a database? Would it be a factory that has database access? Would you bleed the view specific classes like System.Web.Mvc in to the Repository? Something else? For example, if you have a drop down list of cities, you would reference a SelectList object in the root of your View Model object, right next to your DomainModel reference: public class CustomerForm { public CustomerAddress address {get;set;} public SelectList cities {get;set;} } The cities should come from a database and be in the form of a select list object. The hope is that you don't create a special Repository method to extract out just the distinct cities, then create a redundant second SelectList object only so you have the right data types.

• UITableViewCell background size

  - by quano

  I'm trying to set the size of my background to be a little shorter than the default, creating some space between the cells. This has proven to be difficult. Setting the frame of the background view seems to do nothing: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSString *reuseIdentifier = @"cell"; UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:reuseIdentifier]; if (!cell) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:reuseIdentifier] autorelease]; // Set up the cell... cell.contentView.backgroundColor = [UIColor clearColor]; cell.backgroundView = [[[UIView alloc] initWithFrame:CGRectMake(0, 4, 320, 42)] autorelease]; cell.backgroundView.backgroundColor = [UIColor blackColor]; cell.backgroundView.alpha = .2; cell.selectedBackgroundView = [[[UIView alloc] initWithFrame:CGRectMake(0, 4, 320, 42)] autorelease]; cell.selectedBackgroundView.backgroundColor = [UIColor whiteColor]; cell.selectedBackgroundView.alpha = .2; cell.font = [UIFont fontWithName:@"MarkerFelt-Thin" size:22.0f]; cell.selectedTextColor = [UIColor blackColor]; cell.textColor = [UIColor whiteColor]; NSDictionary *dict = [files objectAtIndex:indexPath.row]; cell.text = [dict objectForKey:@"name"]; return cell; } Any help? Also, setting the selected background view doesn't do anything. When a cell is selected, the background is completely blank. Why is this? I'm using iPhone OS 2.2.1. I also do this: - (void)viewDidLoad { [super viewDidLoad]; self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone; self.tableView.backgroundColor = [UIColor clearColor]; self.tableView.rowHeight = 50.0f; } You can download the code here (made a small project for this issue only): http://dl.dropbox.com/u/608462/tabletest2.zip

• How do you display a list of images, from a folder on hard drive, on ASP.NET website?

  - by Jordan S

  I am trying to make a simple photo gallery website. Using ASP.NET and C#. Right now I don't have a server set up but I am just using the development one that Visual Studio Starts when you make a website project and run it. I have a folder on my hard drive that contains an unknown number of images. I want to write a piece of code that will go through each image and add them to the default webpage. I have tried this code but it doesn't work. What am I doing wrong? Should I be using a ListView control or a DataView or something like that? Do I need to add a virtual directory in order to access the images? If so, how do I to that on this test server? ALSO, how do I set the position and alignment of these pictures? For example, how would I make it so that the pictures are in a line vertically and centered on the webpage? protected void Page_Load(object sender, EventArgs e) { string[] filesindirectory = Directory.GetFiles(@"C:\Users\Jordan\Desktop\Web Images"); int i = 1; foreach (string s in filesindirectory) { Image img = new Image(); img.ID = "image" + i.ToString(); img.ImageUrl = s; img.Visible = true; Page.Controls.Add(img); i++; } }

• Why is my app delegate's didFinishLaunchingWithOptions method all of sudden being called AFTER my Ro

  - by BeachRunnerJoe

  Hi. I've been playing with the iPad's SplitView template in Xcode. Here are two of the many important methods that are auto-generated for you by the Split View-based Application template... AppNameAppDelegate.m #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after app launch rootViewController.managedObjectContext = self.managedObjectContext; // Add the split view controller's view to the window and display. [window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; } RootViewController.m #pragma mark - #pragma mark View lifecycle - (void)viewDidLoad { [super viewDidLoad]; self.clearsSelectionOnViewWillAppear = NO; self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0); NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } } When you build and run the project before making any changes at all, the application:didFinishLaunchingWithOptions method is called before the RootViewController:viewDidLoad method is called. I'm new to iPhone development, but I'm assuming this is the correct and typical sequence. However, as soon as I changed the RootViewController code and set it as a subclass of UIViewController (instead of UITableViewController by default), and made the respective adjustments in Interface Builder, suddenly the RootViewController:viewDidLoad is being called before the application:didFinishLaunchingWithOptions method. I need to get it back to the way it was working before because, as you can see in the code, the viewDidLoad method depends on didFinishLauchingWithOptions method to execute so it can set the rootViewController's managedObjectContext that it uses to perform the fetch request. Any ideas what caused this? Any ideas how I can fix this? Thanks so much in advance for your help! I'm gonna keep researching and playing with the code.

• Salesforce/PHP - outbound messages (SOAP) - memory limit issue

  - by Phill Pafford

  I'm using Salesforce to send outbound messages (via SOAP) to another server. The server can process about 8 messages at a time, but will not send back the ACK file if the SOAP request contains more than 8 messages. SF can send up to 100 outbound messages in 1 SOAP request and I think this is causing a memory issue with PHP. If I process the outbound messages 1 by 1 they all go through fine, I can even do 8 at a time with no issues. But larger sets are not working. ERROR in SF: org.xml.sax.SAXParseException: Premature end of file Looking in the HTTP error logs I see that the incoming SOAP message looks to be getting cut of which throws a PHP warning stating: Premature end of data in tag ... PHP Fatal error: Call to a member function getAttribute() on a non-object This leads me to believe that PHP is having a memory issue and can not parse the incoming message due to it's size. I was thinking I could just set: ini_set('memory_limit', '64M'); But would this be the correct approach? Is there a way I could set this to increase with the incoming SOAP request dynamically? UPDATE: Adding some code $data = fopen('php://input','rb'); $headers = getallheaders(); $content_length = $headers['Content-Length']; $buffer_length = 1000; $fread_length = $content_length + $buffer_length; $content = fread($data,$fread_length); /** * Parse values from soap string into DOM XML */ $dom = new DOMDocument(); $dom->loadXML($content); ....

• Fluent NHibernate IDictionary with composite element mapping

  - by Alessandro Di Lello

  Hi there, i have these 2 classes: public class Category { IDictionary<string, CategoryResorce> _resources; } public class CategoryResource { public virtual string Name { get; set; } public virtual string Description { get; set; } } and this is xml mapping <class name="Category" table="Categories"> <id name="ID"> <generator class="identity"/> </id> <map name="Resources" table="CategoriesResources" lazy="false"> <key column="EntityID" /> <index column="LangCode" type="string"/> <composite-element class="Aca3.Models.Resources.CategoryResource"> <property name="Name" column="Name" /> <property name="Description" column="Description"/> </composite-element> </map> </class> and i'd like to write it with Fluent. I found something similar and i was trying with this code: HasMany(x => x.Resources) .AsMap<string>("LangCode") .AsIndexedCollection<string>("LangCode", c => c.GetIndexMapping()) .Cascade.All() .KeyColumn("EntityID"); but i dont know how to map the CategoryResource entity as a composite element inside the Category element. Any advice ? thanks

• Programmatic skins in Flex

  - by Flexer

  Hi, I am having 2 problems creating programmatic skin for Canvas. First problem: I would like to have background with rounded corners and I am using GraphicsUtil.drawRoundRectComplex in order to have round corners for only the upper two corners. The problem is that drawRoundRectComplex takes for each corner one single parameter - the corner radius. However my scaleX and scaleY factors are different and in fact the corners are not properly rounded because I either can set the radius using scaleX or scaleY. Graphics.drawRoundRect is better because it takes two parameters for the corners - elipse width and height and then you could apply both scale factors but it doesn't allow me to specify different radius for different corners. I am looking for an idea how to use GraphicsUtil.drawRoundRectComplex when scaleX and scaleY are different. Second problem: Even though I set my programmatic skin through style - < the skin's updateDisplayList gets executed only once and after that somehow "backgroundImage" style gets "undefined" and my programmatic skin is not associated anymore to the Canvas instance. As a workaround I am setting on each resize event "backgroundImage" style again but this is ugly. What could cause such "silent" resetting of the "backgroundImage" style to undefined? Thanks!

• UiModeManager - NightMode (FroYo)

  - by Kaloer

  Hi there, I have been trying to turn off the buttons' light in my application using the UiModeManager's nightmode function. The default Desk Clock application (Nexus One) turns off the buttons' light when it is dimmed, and I want to do this as well. I've tried using the following code: UiModeManager mgr = (UiModeManager) getSystemService(UI_MODE_SERVICE); mgr.setNightMode(UiModeManager.MODE_NIGHT_YES); The UiModeManager.setNightMode(int mode) documentation says this: Sets the night mode. Changes to the night mode are only effective when the car or desk mode is enabled on a device. Does that mean that the device has to be physically in a desk dock? I can set the device to car mode using the UiModeManager.enableCarMode(int flags) method. This works fine, but it doesn't turn off the lights, it only dims the screen's backlight. Is there a way to set the device into desk mode without using a physical desk dock? As the FroYo source code is not yet released, I cannot look at the build-in Desk Clock application. Thanks in advantage.

• Generic wrapper for System.Web.Caching.Cache functions

  - by David Neale

  I've created a generic wrapper for using the Cache object: public class Cache<T> where T : class { public Cache Cache {get;set;} public CachedKeys Key {get;set;} public Cache(Cache cache, CachedKeys key){ Cache = cache; Key = key; } public void AddToCache(T obj){ Cache.Add(Key.ToString(), obj, null, DateTime.Now.AddMinutes(5), System.Web.Caching.Cache.NoSlidingExpiration, System.Web.Caching.CacheItemPriority.Normal, null); } public bool TryGetFromCache(out T cachedData) { cachedData = Cache[Key.ToString()] as T; return cachedData != null; } public void RemoveFromCache() { Cache.Remove(Key.ToString()); } } The CachedKeys enumeration is just a list of keys that can be used to cache data. The trouble is, to call it is quite convuluted: var cache = new Cache<MyObject>(Page.Cache, CachedKeys.MyKey); MyObject myObject = null; if(!cache.TryGetFromCache(out myObject)){ //get data... cache.AddToCache(data); //add to cache return data; } return myObject; I only store one instance of each of my objects in the cache. Therefore, is there any way that I can create an extension method that accepts the type of object to Cache and uses (via Reflection) its Name as the cache key? public static Cache<T> GetCache(this Cache cache, Type cacheType){ Cache<cacheType> Cache = new Cache<cacheType>(cache, cacheType.Name); } Of course, there's two errors here: Extension methods must be defined in a non-generic static class The type or namespace name 'cacheType' could not be found This is clearly not the right approach but I thought I'd show my working. Could somebody guide me in the right direction?

• Forcing an item to remain in place in a jQuery UI Sortable list

  - by calumbrodie

  I've set up a jQuery sortable list but I need to be able to keep some items in the sortable 'fixed' in place and for the other items to sort around them. I thought that there would be built in methods to achieve this, alas this is not the case. I'm able to set up the list and not include the items in question: <ul id="fruit"> <li class="fixed">apples</li> <li>oranges</li> <li>bananas</li> <li>pineapples</li> <li>grapes</li> <li class="fixed">pears</li> <li>mango</li> </ul> <script type="text/javascript"> $('#fruit').sortable({items: "li:not('.fixed')"}) </script> This stops me from drag/dropping these items but they still move if the items around them are sorted. There may be a way to do this using the many callbacks that this method has but I've been unable to work this out. Maybe this method would be a good addition to the UI Sortable options?

• How i can add border to ListViewItem, ListView in GridView mode.

  - by Andrew

  Hello! I want to have a border around ListViewItem (row in my case). ListView source and columns generated during Runtime. In XAML i have this structure: <ListView Name="listViewRaw"> <ListView.View> <GridView> </GridView> </ListView.View> </ListView> During Runtime i bind listview to DataTable, adding necessary columns and bindings: var view = (listView.View as GridView); view.Columns.Clear(); for (int i = 0; i < table.Columns.Count; i++) { GridViewColumn col = new GridViewColumn(); col.Header = table.Columns[i].ColumnName; col.DisplayMemberBinding = new Binding(string.Format("[{0}]", i.ToString())); view.Columns.Add(col); } listView.CoerceValue(ListView.ItemsSourceProperty); listView.DataContext = table; listView.SetBinding(ListView.ItemsSourceProperty, new Binding()); So i want to add border around each row, and set border behavior (color etc) with DataTriggers (for example if value in 1st column = "Visible", set border color to black). Can i put border through DataTemplate in ItemTemplate? I know solution, where you manipulate with CellTemplates, but i don't really like it. I want something like this if this even possible. <DataTemplate> <Border Name="Border" BorderBrush="Transparent" BorderThickness="2"> <ListViewItemRow><!-- Put my row here, but i ll know about table structure only during runtime --></ListViewItemRow> </Border> </DataTemplate>

• Kohana multi language website

  - by Sobek

  .I'm trying to set up a multi language website with kohana v3, following this tutorial: http://kerkness.ca/wiki/doku.php?id=example_of_a_multi-language_website Routing to a controller or action within i.e. website/controller/action seems to work as the url is properly redirected to website/lang/controller/action. However this is not working for ajax request calls. I have to manually edit the url with the appropriate language, to successfully retrieve the data. This also applies for anchors on the html page. In addition to this problem, the overflow parameter 'id' also doesn't work. It takes the 'lang' variable as its parameter. I have setup my default route just like in the tutorial i.e.: Route::set('default', '((<lang>)(/)(<controller>)(/<action>(/<id>)))', array('lang' => "({$langs_abr})",'id'=>'.+')) ->defaults(array('lang' => $default_lang,'controller' => welcome', 'action' => 'index')); Any help is much appreciated !

• Is there a way to update a ViewModel in MVC2?

  - by Juvaly

  This code works: [HttpPost] public ActionResult Edit(int id, FormCollection fc) { Movie movie = ( from m in _ctx.Movie.Include("MovieActors") where m.MovieID == id select m ).First(); MovieActorViewModel movieActor = new MovieActorViewModel(movie); if (TryUpdateModel(movieActor)) { _ctx.ApplyPropertyChanges(movieActor.Movie.EntityKey.EntitySetName, movieActor.Movie); _ctx.SaveChanges(); } return View(movieActor); } However, I am not sure how to test this, and in general would much rather have the method take a typed model like: [HttpPost] public ActionResult Edit(MovieActorViewModel movieActor) Is this possible? What changes to my MovieActorViewModel class do I need to make in order to enable this? That class looks like this: public class MovieActorViewModel { public Movie Movie { get; set; } public Actor Actor { get; set; } public PublisherDealViewModel(Movie movie) { this.Movie = movie; this.Actor = ( from a in this.Movie.Actors where a.ActorID == 1 select a ).First(); } } The view is typed (inherits ViewPage) simple: <% using (Html.BeginForm()) {%> Movie Title: <%= Html.TextBoxFor(model=>model.Movie.Title) %><br/> Actor Name: <%= Html.TextBoxFor(model=>model.Actor.Name) %> <% } %>

• DataGridViewColumn.DataPropertyName Property

  - by Captain Comic

  Hi I have a DataGridView control and I want to populate it with data. I use DataSource property // dgvDealAsset is DataGridView private void DealAssetListControl_Load(object sender, EventArgs e) { dgvDealAssets.AutoGenerateColumns = false; dgvDealAssets.DataSource = DealAssetList.Instance.Values.ToList(); } Now problem number one. The class of my collection does not contain only simple types that I can map to columns using DataPropertyName. This is the class that is contained in collection. class MyClass { public String Name; MyOtherClass otherclass; } class MyOtherClass { public String Name; } Now I am binding properties of MyClass to columns col1.DataPropertyName = "Name" // Ok col2.DataPropertyName = "otherclass" // Not OK - I will have empty cell The problem is that I want to display otherclass.Name field. But if I try to write col2.DataPropertyName = "otherclass.Name" I get empty cell. I tried to manually set the column private void DealAssetListControl_Load(object sender, EventArgs e) { dgvDealAssets.AutoGenerateColumns = false; dgvDealAssets.DataSource = DealAssetList.Instance.Values.ToList(); // iterate through rows and set the column manually foreach (DataGridViewRow row in dgvDealAssets.Rows) { row.Cells["Column2"].Value = ((DealAsset)row.DataBoundItem).otherclass.Name; } But this foreach cycle takes about minute to complete (2k elements). How to solve this problem?

• how to show avg of employees salary in a NSTextField using NSArrayController and cocoa bindings

  - by Miraaj

  Hi all, I am new to cocoa bindings so I tried to make a simple application which will simply calculate avg of employees salary and display it in a text field, using cocoa bindings. I followed these steps: Made the model class : Person with one property for now - @property (readwrite, assign) int salary; In the application delegate class I initialized a mutable array : personArray with certain objects like this: Person *person1 = [[Person alloc] init]; person1.salary = 5000; Person *person2 = [[Person alloc] init]; person2.salary = 15000; Person *person3 = [[Person alloc] init]; person3.salary = 7000; Person *person4 = [[Person alloc] init]; person4.salary = 9000; Person *person5 = [[Person alloc] init]; person5.salary = 11000; personArray= [[NSMutableArray alloc] initWithObjects:person1, person2, person3, person4, person5,nil]; In IB I dropped a NSArrayController object, set its mode as Class - Person, added key salary in attribute pane. Then in bindings pane, binded contents array to ApplicationDelegate class with model key path set to self.personArray. Dropped a NSTextField on window. Binded its value to ArrayController object. Assigned controller key as - arrangedObjects. Assigned Model key path to @avg.salary When I executed the application I found no value being displayed in the text field. Can anyone suggest me where I may be wrong? Thanks, Miraaj

• Command-Line Parsing API from TestAPI library - Type-Safe Commands how to

  - by MicMit

  Library at http://testapi.codeplex.com/ Excerpt of usage from http://blogs.msdn.com/ivo_manolov/archive/2008/12/17/9230331.aspx A third common approach is forming strongly-typed commands from the command-line parameters. This is common for cases when the command-line looks as follows: some-exe COMMAND parameters-to-the-command The parsing in this case is a little bit more involved: Create one class for every supported command, which derives from the Command abstract base class and implements an expected Execute method. Pass an expected command along with the command-line arguments to CommandLineParser.ParseCommand – the method will return a strongly-typed Command instance that can be Execute()-d. // EXAMPLE #3: // Sample for parsing the following command-line: // Test.exe run /runId=10 /verbose // In this particular case we have an actual command on the command-line (“run”), which we want to effectively de-serialize and execute. public class RunCommand : Command { bool? Verbose { get; set; } int? RunId { get; set; } public override void Execute() { // Implement your "run" execution logic here. } } Command c = new RunCommand(); CommandLineParser.ParseArguments(c, args); c.Execute(); ============================ I don't get if we instantiate specific class before parsing arguments , what's the point of command line argument "run" which is very first one. I thought the idea was to instantiate and execute command/class based on a command line parameter ( "run" parameter becomes instance RunCommand class, "walk" becomes WalkCommand class and so on ). Can it be done with the latest version ?

• Crystal report subreport parameter autobinding logic feeds duplicate parameters to different subrepo

  - by quillbreaker

  I have a report, and I place the same subreport within the footer twice. The report has three parameters and the subreport has four parameters. When I try to run the report through the report designer, it prompts me for seven parameters instead of the eleven I was hoping for. It prompts for one set of parameters for the subreport (with a default prompt of @parameter(subreport.rpt)/@parameter(subreport.rpt - 01), and passes the same set of parameters to both subreports. This isn't what I want the report to do. Furthermore, if I look at 'show report parameters', it does show eleven parameters, with the same value for both subreport parameter sets. So it knows that it's two different subreports, but it does not want to let me enter it that way. Is there some way I can make crystal designer realize that it should take different values for each subreport? The only solution I've found is to add 8 more parameters, one for each subreport / subreport parameter combination, and bind them individually. It works, but it feels like a workaround. Does anyone have a better solution?

  Take the following example data: Payroll Forname Surname Month Year Amount 0000001 James Bond 3 2011 144.00 0000001 James Bond 6 2012 672.00 0000001 James Bond 7 2012 240.00 0000001 James Bond 8 2012 1744.50 0000002 Elvis Presley 3 2011 1491.00 0000002 Elvis Presley 6 2012 189.00 0000002 Elvis Presley 7 2012 1816.50 0000002 Elvis Presley 8 2012 1383.00 How would i PIVOT this on the Year + Month (eg: 201210) but preserve Payroll, Forename & Surname as seperate columns, for example, the above would become: Payroll Forename Surname 201103 201206 201207 201208 0000001 James Bond 144.00 672.00 240.00 1744.50 0000002 Elvis Presley 1491.00 189.00 1816.50 1383.00 I'm assuming that because the Year + Month names can change then i will need to employ dynamic SQL + PIVOT - i had a go but couldnt even get the code to parse, nevermind run - any help would be most appreciated! Edit: What i have so far: INSERT INTO #tbl_RawDateBuffer ( PayrollNumber , Surname , Forename , [Month] , [Year] , AmountPayable ) SELECT PayrollNumber , Surname , Forename , [Month] , [Year] , AmountPayable FROM RawData WHERE [Max] > 1500 DECLARE @Columns AS NVARCHAR(MAX) DECLARE @StrSQL AS NVARCHAR(MAX) SET @Columns = STUFF((SELECT DISTINCT ',' + QUOTENAME(CONVERT(VARCHAR(4), c.[Year]) + RIGHT('00' + CONVERT(VARCHAR(2), c.[Month]), 2)) FROM #tbl_RawDateBuffer c FOR XML PATH('') , TYPE ).value('.', 'NVARCHAR(MAX)'), 1, 1, '') SET @StrSQL = 'SELECT PayrollNumber, ' + @Columns + ' from ( select PayrollNumber , CONVERT(VARCHAR(4), [Year]) + RIGHT(''00'' + CONVERT(VARCHAR(2), [Month]), 2) dt from #tbl_RawDateBuffer ) x pivot ( sum(AmountPayable) for dt in (' + @Columns + ') ) p ' EXECUTE(@StrSQL) DROP TABLE #tbl_RawDateBuffer

• jQuery Validation Plugin: Validating Checkboxes with Different Names

  - by Michael

  I have a set of 4 checkboxes, all with different names, and require that at least 1 is checked. I know there are a few posts on here already trying to answer this question. The solution that seems to be most logical to me is the answer posted on Question 1734840, but I can't seem to get it working! What's wrong with my code? Or any other new coding ideas to get this working? I have set the class on all of them to 'require-one'. My jQuery code is $(document).ready(function(){ $("#itemForm").validate({ highlight: function(element, errorClass, validClass) { $(element).addClass(errorClass).removeClass(validClass); $(element.form).find("label[for=" + element.name + "]") .addClass("radioerror"); }, unhighlight: function(element, errorClass, validClass) { $(element).removeClass(errorClass).addClass(validClass); $(element.form).find("label[for=" + element.name + "]") .removeClass("radioerror"); }, rules: { 'require-one': { required : { depends: function(element) { var allBoxes = $('.require-one'); if (allBoxes.filter(':checked').length == 0) { if (allBoxes.eq(element).length != 0) { return true; } } return false; } } } , }, errorPlacement: function(error, element) { if ( element.is("#other_descrip") ) error.appendTo("#othererror" ); if ( element.is("#itemlist") ) error.appendTo("#itemerror" ); } }); });

• Redirect to new page if cookie doesn't exist or if the value of cookie is 'false'

  - by liquilife

  I have a DOB 'Are you over 18' script which when the form is filled out, validates if they are over 18 or not for a tobacco site I am working on. When this form is filled it stores a cookie 'ageCheck' with a value of either true or false. I'm having some issues with a bit of javascript which is stored on all the pages to determine if they can view the page or if they need to be redirected to the verification page. The javascript is supposed to set a div ID to 'display:block' if passed and if no cookie is found OR the cookie value is false is supposed to redirect them to the age verification page. However, it's just not working. I see the cookies are set correctly. Below is my code.. any help is appreciated. <script> document.body.onload = function() { var ageCheck = getCookie('ageCheck'); if ('true' == ageCheck) { document.getElementById('content').style.display = ''; } else { document.location = '/ageCheck.html'; } } function getCookie(c_name) { if (document.cookie.length > 0) { c_start = document.cookie.indexOf(c_name + "="); if (c_start != -1) { c_start = c_start + c_name.length + 1; c_end = document.cookie.indexOf(";", c_start); if (c_end == -1) c_end = document.cookie.length; return unescape(document.cookie.substring(c_start, c_end)); } } return ""; } </script>
