• Returning a CSS element

  - by TMP

  Is there a way to return a CSS element? I was using Adobe Edge and adding some of my own code in their code tab, but in order to create boundaries I would need to keep track of margin-top or margin-left. The following code works to move the element "woo" but I'm not sure how to call the elements to add something like "|| sym.$("woo").css({"margin-left"0px"}) to the move left code. //Move RIGHT if (e.which == 39) { sym.$("woo").css({"margin-left":"+=10px"}); } //Move UP else if (e.which == 38) { sym.$("woo").css({"margin-top":"-=10px"}); } //Move Left else if (e.which == 37) { sym.$("woo").css({"margin-left":"-=10px"}); } //Move DOWN else if (e.which == 40) { sym.$("woo").css({"margin-top":"+=10px"}); } EDIT: I changed the Left if statement to the following: else if (e.which == 37 && ($("woo").css("margin-left")>0)) { It seems to be working to some extent except for now it won't move left at all! I tried doing <0 too in case I was screwing up a sign but it won't let me move the element left either.

• Troubleshooting "Parse error: syntax error, unexpected T_STRING" in echo statement

  I am back to php after like 5 years and I need help with the following please:) It keeps telling me the error: Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in header.php (in the first echo invoke) <?php $result = mysql_query("SELECT * FROM menu WHERE disabled=0 ORDER BY orderx ASC") or die(mysql_error()); $i=1; while($row = mysql_fetch_array($result)) { echo "<li class='sddm'.$i.'

• Looking for good PHP editor or IDE with 'IntelliSense'

  - by Andrew

  Hello, I'm looking for suitable PHP Editor or IDE with syntax auto-completion. I've tried trial versions of programs like Zend Studio, PHPDesigner, NetBeans PHP, NuSphere PhpED, and similar -- but none of them fully satisfied me. I quite liked hint window with detailed info about what function does and what it returns. Also I liked the way NetBeans auto-complete code (for example inserts all required parameters in function declaration as "dummy fields" and then you can jump between them using TAB in order to edit them). On the other hand, environment of NetBeans doesn't belong to the nicest. In this regard I prefer PHPDesigner with its sleek and light interface. At this moment I don't use any of the debugging options, since I don't know yet how to use profiller, breakpoints, watches and what not, so at this point my only concern is good autocompletion. For this purpose NetBean would be great choice, but with future in mind I am not sure debugging will be good in NetBeans, especially as I would prefer to use remote Linux server for this. So in short, I'm looking for editor that: Have similar code auto-completion (IntelliSense) like NetBeans Allow you to debug code using remote server (or sets up own debugging server like PHPDesigner does) without need to run Apache and similar on local computer Is preferably easy to use / intuitive interface Any ideas?

• Find items with belongs_to associations in Rails?

  - by dannymcc

  Hi Everyone, I have a model called Kase each "Case" is assigned to a contact person via the following code: class Kase < ActiveRecord::Base validates_presence_of :jobno has_many :notes, :order => "created_at DESC" belongs_to :company # foreign key: company_id belongs_to :person # foreign key in join table belongs_to :surveyor, :class_name => "Company", :foreign_key => "appointedsurveyor_id" belongs_to :surveyorperson, :class_name => "Person", :foreign_key => "surveyorperson_id" I was wondering if it is possible to list on the contacts page all of the kases that that person is associated with. I assume I need to use the find command within the Person model? Maybe something like the following? def index @kases = Person.Kase.find(:person_id) or am I completely misunderstanding everything again? Thanks, Danny EDIT: If I use: @kases= @person.kases I can successfully do the following: <% if @person.kases.empty? %> No Cases Found <% end %> <% if @person.kases %> This person has a case assigned to them <% end %> but how do I output the "jobref" field from the kase table for each record found?

• Can I use a static cache Helper method in a NET MVC controller?

  - by Euston

  I realise there have been a few posts regarding where to add a cache check/update and the separation of concerns between the controller, the model and the caching code. There are two great examples that I have tried to work with but being new to MVC I wonder which one is the cleanest and suits the MVC methodology the best? I know you need to take into account DI and unit testing. Example 1 (Helper method with delegate) ...in controller var myObject = CacheDataHelper.Get(thisID, () => WebServiceServiceWrapper.GetMyObjectBythisID(thisID)); Example 2 (check for cache in model class) in controller var myObject = WebServiceServiceWrapper.GetMyObjectBythisID(thisID)); then in model class.............. if (!CacheDataHelper.Get(cachekey, out myObject)) { //do some repository processing // Add obect to cache CacheDataHelper.Add(myObject, cachekey); } Both use a static cache helper class but the first example uses a method signature with a delegate method passed in that has the name of the repository method being called. If the data is not in cache the method is called and the cache helper class handles the adding or updating to the current cache. In the second example the cache check is part of the repository method with an extra line to call the cache helper add method to update the current cache. Due to my lack of experience and knowledge I am not sure which one is best suited to MVC. I like the idea of calling the cache helper with the delegate method name in order to remove any cache code in the repository but I am not sure if using the static method in the controller is ideal? The second example deals with the above but now there is no separation between the caching check and the repository lookup. Perhaps that is not a problem as you know it requires caching anyway?

• ASP.NET output caching - dynamically update dependencies

  - by ColinE

  Hi All, I have an ASP.NET application which requires output caching. I need to invalidate the cached items when the data returned from a web service changes, so a simple duration is not good enough. I have been doing a bit of reading about cache dependencies and think I have the right idea. It looks like I will need to create a cache dependency to my web service. To associate the page output with this dependency I think I should use the following method: Response.AddCacheItemDependency(cacheKey); The thing I am struggling with is what I should add to the cache? The dependency my page has is to a single value returned by the web service. My current thinking is that I should create a Custom Cache Dependency via subclassing CacheDependency, and store the current value in the cache. I can then use Response.AddCacheItemDependency to form the dependency. I can then periodically check the value and for a NotifyDependencyChange in order to invalidate my cached HTTP response. The problem is, I need to ensure that the cache is flushed immediately, so a periodic check is not good enough. How can I ensure that my dependant object in the cache which represents the value returned by the web service is re-evaluated before the HTTP response is fetched from the cache? Regards, Colin E.

• Can a stateless WCF service benefit from built-in database connection pooling?

  - by vladimir

  I understand that a typical .NET application that accesses a(n SQL Server) database doesn't have to do anything in particular in order to benefit from the connection pooling. Even if an application repeatedly opens and closes database connections, they do get pooled by the framework (assuming that things such as credentials do not change from call to call). My usage scenario seems to be a bit different. When my service gets instantiated, it opens a database connection once, does some work, closes the connection and returns the result. Then it gets torn down by the WCF, and the next incoming call creates a new instance of the service. In other words, my service gets instantiated per client call, as in [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]. The service accesses an SQL Server 2008 database. I'm using .NET framework 3.5 SP1. Does the connection pooling still work in this scenario, or I need to roll my own connection pool in form of a singleton or by some other means (IInstanceContextProvider?). I would rather avoid reinventing the wheel, if possible.

• MySQL: Complex Join Statement involving two tables and a third correlation table

  - by Stephen

  I have two tables that were built for two disparate systems. I have records in one table (called "leads") that represent customers, and records in another table (called "manager") that are the exact same customers but "manager" uses different fields (For example, "leads" contains an email address, and "manager" contains two fields for two different emails--either of which might be the email from "leads"). So, I've created a correlation table that contains the lead_id and manager_id. currently this correlation table is empty. I'm trying to query the "leads" table to give me records that match either "manager" email field with the single "leads" email field, while at the same time ignoring fields that have already been added to the "correlated" table. (this way I can see how many leads that match have not yet been correlated.) Here's my current, invalid SQL attempt: SELECT leads.id, manager.id FROM leads, manager LEFT OUTER JOIN correlation ON correlation.lead_id = leads.id WHERE correlation.id IS NULL AND leads.project != "someproject" AND (manager.orig_email = leads.email OR manager.dest_email = leads.email) AND leads.created BETWEEN '1999-01-01 00:00:00' AND '2010-05-10 23:59:59' ORDER BY leads.created ASC; I get the error: Unknown column 'leads.id' in 'on clause' Before you wonder: there are records in the "leads" table where leads.project != "someproject" and leads.created falls between those dates. I've included those additional parameters for completeness.

• Help with MySQL Query using CASE statement

  - by hairdresser-101

  I am trying to group a number of customers together based on their "Head Office" or "Parent" location. THis works ok except for a flaw which I didn't forsee when I was developing my system... For customers that did not have a "Parent" (standalone business) I defaulted the parent_id to 0. Therefore, my data would look like this: id parent_id customer 1 0 CustName#1 2 4 CustName#2 - Melbourne 3 4 CustName#2 - Sydney 4 0 CustName#2 (Head Office) What I want to do is Group my results together so that I have one row for CustName#1 and one row for CustName#2 BUT my problem is that there is no parent record for parent_id=0 and these rows are being excluded when using an inner join. I've tried using a case statement but that is not working either (parents are still being ignored) Any help would be greatly appreciated. Here is my query (My CASE is basically trying to get the business_name from the customer table based on the parent_id EXCEPT when the parent_id = 0, THEN just use the customer_name that is listed in the job_summary table): SELECT js.month_of_year, (CASE js.parent_id WHEN 0 THEN js.customer_name ELSE c.business_name END) as customer, SUM(js.jobs), SUM(js.total_cost), sum(js.total_sell) FROM JOB_SUMMARY js INNER JOIN customer c on js.parent_id=c.id group by js.month_of_year, (CASE c.parent_id WHEN 0 THEN js.customer_name ELSE c.business_name END) ORDER BY `customer` ASC

• jQuery Tablesorter - column not sorting alphabetically

  - by McGirl

  I'm not sure what's going wrong here. This is the page: http://www.utexas.edu/ssw/cswr/projects/project-list/ The first column sorts, but it isn't returning data in the correct order (alphabetical). The table itself is being generated by a custom PHP function that pulls info from a WordPress database. I thought that might be the issue, but as you can see the fourth column (End Date) sorts correctly. I also thought it might be the links in the first column that were messing things up, but adding the text-extraction code from this page broke the sorting altogether. This is the jQuery code I'm current using to call Tablesorter: <script type="text/javascript" id="js"> jQuery(document).ready(function($) { $(document).ready(function() { // call the tablesorter plugin, the magic happens in the markup $("#projectTable").tablesorter({ // pass the headers argument and assing a object //debug: true, //sortList: [[0,0]], headers: { 0: { // set the column to sort as text sorter: 'text', }, // assign the secound column (we start counting zero) 1: { // disable it by setting the property sorter to false sorter: false, }, // assign the third column (we start counting zero) 2: { // disable it by setting the property sorter to false sorter: false }, 3: { sorter:'digit' } } }); // Works only with plugin modification $("#projectTable").bind("sortStart",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").show(); } }).bind("sortEnd",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").hide(); } }); }); }); </script> Thanks for your help!

• Retrieve specific preceding sibling nodes attributes

  - by Matthieu BROUILLARD

  Is there an XPath way of recovering directly one specific attribute of preceding sibling nodes of an XML node using an XPath query? In the following example, I would like to retrieve the values of the alt attribute of each img nodes that precede the div element marked with the id=marker. <content> <img alt="1" src="file.gif" /> <img alt="2" src="file.gif" /> <img alt="3" src="file.gif" /> <img alt="4" src="file.gif" /> <div id='marker'></div> </content> For this example, I want to retrieve the values 1 2 3 4. I use the following XPath query //div[@id='marker']/preceding-sibling::img in order to retrieve the node list I want <img alt="1" src="file.gif"/> <img alt="2" src="file.gif"/> <img alt="3" src="file.gif"/> <img alt="4" src="file.gif"/> As it is a node list I can then iterate on the nodes to retrieve the attribute value I am looking for, but is there an XPath way of doing it? I would have expected to be able to write something like: //div[@id='marker']/preceding-sibling::img@alt or //div[@id='marker']/preceding-sibling@alt::img but I don't even know if it is possible once you have used an XPath Axe like preceding-sibling.

• How can I find "People's Contacts" folders via Outlook's object model?

  - by Dennis Palmer

  I have some code that locates all the contact folders that a user has access to by iterating through the Application.Session.Stores collection. This works for the user's contacts and also all the public contacts folders. It also finds all the contacts folders in additional mailbox accounts that the user has added via the Tools - Account Settings... menu command. However, this requires the user to have full access to the other person's account. When a user only has access to another person's contacts, then that person's contacts show up under the "People's Contacts" group in the Contacts view. How do I find those contact folders that don't show up under Session.Stores? In order to see the other user's contacts folder without adding access to their full mailbox, click File - Open - Other User's Folder... from the Outlook menu. In the dialog box, enter the other user's name and select Contacts from the Folder type drop down list. Here's the code (minus the error checking and logging) I'm using to find a list of all the user's Outlook contact folders. I know this can (and maybe should) be done using early binding to the Outlook.Application type, but that doesn't affect the results. EnumerateFolders is recursive so that it searches all sub folders. Dim folderList = New Dictionary(Of String, String) Dim outlookApp = CreateObject(Class:="Outlook.Application") For Each store As Object In outlookApp.Session.Stores EnumerateFolders(folderList, store.GetRootFolder) Next Private Sub EnumerateFolders(ByRef folderList As Dictionary(Of String, String), ByVal folder As Object) Try If folder.DefaultItemType = 2 Then folderList.Add(folder.EntryID, folder.FolderPath.Substring(2)) End If For Each subFolder As Object In folder.Folders EnumerateFolders(folderList, subFolder) Next Catch ex As Exception End Try End Sub

• Linq: Why won't Group By work when Querying DataSets?

  - by jrcs3

  While playing with Linq Group By statements using both DataSet and Linq-to-Sql DataContext, I get different results with the following VB.NET 10 code: #If IS_DS = True Then Dim myData = VbDataUtil.getOrdersDS #Else Dim myData = VbDataUtil.GetNwDataContext #End If Dim MyList = From o In myData.Orders Join od In myData.Order_Details On o.OrderID Equals od.OrderID Join e In myData.Employees On o.EmployeeID Equals e.EmployeeID Group By FullOrder = New With { .OrderId = od.OrderID, .EmployeeName = (e.FirstName & " " & e.LastName), .ShipCountry = o.ShipCountry, .OrderDate = o.OrderDate } _ Into Amount = Sum(od.Quantity * od.UnitPrice) Where FullOrder.ShipCountry = "Venezuela" Order By FullOrder.OrderId Select FullOrder.OrderId, FullOrder.OrderDate, FullOrder.EmployeeName, Amount For Each x In MyList Console.WriteLine( String.Format( "{0}; {1:d}; {2}: {3:c}", x.OrderId, x.OrderDate, x.EmployeeName, x.Amount)) Next With Linq2SQL, the grouping works properly, however, the DataSet code doesn't group properly. Here are the functions that I call to create the DataSet and Linq-to-Sql DataContext Public Shared Function getOrdersDS() As NorthwindDS Dim ds As New NorthwindDS Dim ota As New OrdersTableAdapter ota.Fill(ds.Orders) Dim otda As New Order_DetailsTableAdapter otda.Fill(ds.Order_Details) Dim eda As New EmployeesTableAdapter eda.Fill(ds.Employees) Return ds End Function Public Shared Function GetNwDataContext() As NorthwindL2SDataContext Dim s As New My.MySettings Return New NorthwindL2SDataContext(s.NorthwindConnectionString) End Function What am I missing? If it should work, how do I make it work, if it can't work, why not (what interface isn't implemented, etc)?

• View Models (ViewData), UserControls/Partials and Global variables - best practice?

  - by elado

  Hi I'm trying to figure out a good way to have 'global' members (such as CurrentUser, Theme etc.) in all of my partials as well as in my views. I don't want to have a logic class that can return this data (like BL.CurrentUser) I do think it needs to be a part of the Model in my views So I tried inheriting from BaseViewData with these members. In my controllers, in this way or another (a filter or base method in my BaseController), I create an instance of the inheriting class and pass it as a view data. Everything's perfect till this point, cause then I have my view data available on the main View with the base members. But what about partials? If I have a simple partial that needs to display a blog post then it looks like this: <%@ Control Language="C#" AutoEventWireup="true" Inherits="ViewUserControl<Post>" %> and simple code to render this partial in my view (that its model.Posts is IEnumerable<Post>): <%foreach (Post p in this.Model.Posts) {%> <%Html.RenderPartial("Post",p); %> <%}%> Since the partial's Model isn't BaseViewData, I don't have access to those properties. Hence, I tried to make a class named PostViewData which inherits from BaseViewData, but then my containing views will have a code to actually create the PostViewData in them in order to pass it to the partial: <%Html.RenderPartial("Post",new PostViewData { Post=p,CurrentUser=Model.CurrentUser,... }); %> Or I could use a copy constructor <%Html.RenderPartial("Post",new PostViewData(Model) { Post=p }); %> I just wonder if there's any other way to implement this before I move on. Any suggestions? Thanks!

• NSOperation for animation loop causes strange scrolling behaviour

  - by Tricky

  Hi, I've created an animation loop which I run as an operation in order to keep the rest of my interface responsive. Whilst almost there, there is still one remaining issue. My UIScrollViews don't seem to be reliably picking up when a user touch ends. What this means is, for example, if a user drags down on a scroll view, when they lift their fingers the scrollview doesn't bounce back into place and the scrollbar remains visible. As if the finger hasn't left the screen. It takes another tap on the scrollview for it to snap to its correct position and the scrollbar to fade away... Here's the loop I created in a subclassed NSOperation: (void)main { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; _displayLink = [[CADisplayLink displayLinkWithTarget: self selector: @selector(animationLoop:)] retain]; [_displayLink setFrameInterval: 1.0f]; [_displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode: NSRunLoopCommonModes]; while (![self isCancelled]) { NSAutoreleasePool *loopPool = [[NSAutoreleasePool alloc] init]; [runLoop runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; [loopPool drain]; } [_displayLink invalidate]; [pool release]; } DOes anyone have any idea what might be going on here, and even better how to fix it... Thanks!

• Using ember-resource with couchdb - how can i save my documents?

  - by Thomas Herrmann

  I am implementing an application using ember.js and couchdb. I choose ember-resource as database access layer because it nicely supports nested JSON documents. Since couchdb uses the attribute _rev for optimistic locking in every document, this attribute has to be updated in my application after saving the data to the couchdb. My idea to implement this is to reload the data right after saving to the database and get the new _rev back with the rest of the document. Here is my code for this: // Since we use CouchDB, we have to make sure that we invalidate and re-fetch // every document right after saving it. CouchDB uses an optimistic locking // scheme based on the attribute "_rev" in the documents, so we reload it in // order to have the correct _rev value. didSave: function() { this._super.apply(this, arguments); this.forceReload(); }, // reload resource after save is done, expire to make reload really do something forceReload: function() { this.expire(); // Everything OK up to this location Ember.run.next(this, function() { this.fetch() // Sub-Document is reset here, and *not* refetched! .fail(function(error) { App.displayError(error); }) .done(function() { App.log("App.Resource.forceReload fetch done, got revision " + self.get('_rev')); }); }); } This works for most cases, but if i have a nested model, the sub-model is replaced with the old version of the data just before the fetch is executed! Interestingly enough, the correct (updated) data is stored in the database and the wrong (old) data is in the memory model after the fetch, although the _rev attribut is correct (as well as all attributes of the main object). Here is a part of my object definition: App.TaskDefinition = App.Resource.define({ url: App.dbPrefix + 'courseware', schema: { id: String, _rev: String, type: String, name: String, comment: String, task: { type: 'App.Task', nested: true } } }); App.Task = App.Resource.define({ schema: { id: String, title: String, description: String, startImmediate: Boolean, holdOnComment: Boolean, ..... // other attributes and sub-objects } }); Any ideas where the problem might be? Thank's a lot for any suggestion! Kind regards, Thomas

• Email function using templates. Includes via ob_start and global vars

  - by Geo

  I have a simple Email() class. It's used to send out emails from my website. <? Email::send($to, $subj, $msg, $options); ?> I also have a bunch of email templates written in plain HTML pierced with a few PHP variables. E.g. /inc/email/templates/account_created.php: <p>Dear <?=$name?>,</p> <p>Thank you for creating an account at <?=$SITE_NAME?>. To login use the link below:</p> <p><a href="https://<?=$SITE_URL?>/account" target="_blank"><?=$SITE_NAME?>/account</a></p> In order to have the PHP vars rendered I had to include the template into my function. But since include does not return the contents but rather just sends it directly to the output, I had to wrap it with the buffer functions: <? abstract class Email { public static function send($to, $subj, $msg, $options = array()) { /* ... */ ob_start(); include '/inc/email/templates/account_created.php'; $msg = ob_get_clean(); /* ... */ } } After that I realized that the PHP vars are not rendered as they are being inside of the function scope, so I had to globalize the variables inside of the template: <? global $SITE_NAME, $SITE_URL, $name; ?> <p>Dear <?=$name?>,</p> ... So the question is whether there is a more elegant solution to this? Mainly I am concerned about my workarounds using ob_start() and global. For some reason that seems to me odd. Or this is pretty much the common practice?

• Please help me with a Git workflow

  - by aaron carlino

  I'm an SVN user hoping to move to Git. I've been reading documentation and tutorials all day, and I still have unanswered questions. I don't know if this workflow will make sense, but here's my situation, and what I would like to get out of my workflow: Multiple developers, all developing locally on their work stations 3 versions of the website: Dev, Staging, Production Here's my dream: A developer works locally on his own branch, say "developer1", tests on his local machine, and commits his changes. Another developer can pull down those changes into his own branch. Merge developer1 - developer2. When the work is ready to be seen by the public, I'd like to be able to "push" to Dev, Staging, or Production. git push origin staging or maybe.. git merge developer1 staging I'm not sure. Like I said, I'm still new to it. Here are my main questions: -Do my websites (Dev, Staging, Production) have to be repositories? And do they have to be "bare" in order to be the recipients of new changes? -Do I want one repository or many, with several branches? -Does this even make sense, or am I on the wrong path? I've read a lot of tutorials, so I'm really hoping someone can just help me out with my specific situation. Thanks so much!

• Pros/cons of reading connection string from physical file vs Application object (ASP.NET)?

  - by HaterTot

  my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production). It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings. I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often). I was considering storing the connection string in Application["ConnectionString"]. So the code would be public static string GetConnectionString { if (Application["ConnectionString"] == null) { XmlDocument doc = new XmlDocument(); doc.Load(HttpContext.Current.Request.PhysicalApplicationPath + "bin/ServerEnvironment.xml"); XmlElement xe = (XmlElement) xnl[0]; switch (xe.InnerText.ToString().ToLower()) { case "local": connString = Settings.Default.ConnectionStringLocal; break; case "development": connString = Settings.Default.ConnectionStringDevelopment; break; case "production": connString = Settings.Default.ConnectionStringProduction; break; default: throw new Exception("no connection string defined"); } Application["ConnectionString"] = connString; } return Application["ConnectionString"].ToString(); } I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons? Do you think I'd see a small performance gain by implementing the function above? THANKS

  - by HansDampf

  Okay, here is my problem: Im implementing an algorithm in Java and part of it will be following: The Question is to how to do what I will explain now in an efficient way. given: array a of length n integer array perm, which is a permutation of [1..n] now I want to shuffle the array a, using the order determined by array perm, i.e. a=[a,b,c,d], perm=[2,3,4,1] ------ shuffledA[b,c,d,a], I figured out I can do that by iterating over the array with: shuffledA[i]=a[perm[i-1]], (-1 because the permutation indexes in perm start with 1 not 0) Now I want to do some operations on shuffledA... And now I want to do the reverse the shuffle operation. This is where I am not sure how to do it. Note that a can hold an item more than once, i.e. a=[a,a,a,a] If that was not the case, I could iterate perm, and find the corresponding indexes to the values. Now I thought that using a Hashmap instead of the the perm array will help. But I am not sure if this is the best way to do.

• ActionScript Tweening Matrix Transform (big problem)

  - by TheDarkIn1978

  i'm attempting to tween the position and angle of a sprite. if i call the functions without tweening, to appear in one step, it's properly set at the correct coordinates and angle. however, tweening it makes it all go crazy. i'm using an rotateAroundInternalPoint matrix, and assume tweening this along with coordinate positions is messing up the results. works fine (without tweening): public function curl():void { imageWidth = 400; imageHeight = 600; parameters.distance = 0.5; parameters.angle = 45; backCanvas.x = imageWidth - imageHeight * parameters.distance; backCanvas.y = imageHeight - imageHeight * parameters.distance; var internalPointMatrix:Matrix = backCanvas.transform.matrix; MatrixTransformer.rotateAroundInternalPoint(internalPointMatrix, backCanvas.width * parameters.distance, 0, parameters.angle); backCanvas.transform.matrix = internalPointMatrix; } doesn't work properly (with tweening): public function curlUp():void { imageWidth = 400; imageHeight = 600; parameters.distance = 0.5; parameters.angle = 45; distanceTween = new Tween(parameters, "distance", None.easeNone, 0, distance, 1, true); angleTween = new Tween(parameters, "angle", None.easeNone, 0, angle, 1, true); angleTween.addEventListener(TweenEvent.MOTION_CHANGE, animateCurl); } private function animateCurl(evt:TweenEvent):void { backCanvas.x = imageWidth - imageHeight * parameters.distance; backCanvas.y = imageHeight - imageHeight * parameters.distance; var internalPointMatrix:Matrix = backCanvas.transform.matrix; MatrixTransformer.rotateAroundInternalPoint(internalPointMatrix, backCanvas.width * parameters.distance, 0, parameters.angle - previousAngle); backCanvas.transform.matrix = internalPointMatrix; previousAngle = parameters.angle; } in order for the angle to tween properly, i had to add a variable that would track it's last angle setting and subtract it from the new one. however, i still can not get this tween to return the same end position and angle as is without tweening. i've been stuck on this problem for a day now, so any help would be greatly appreciated.

• Java Iterators - Trying to get a for each loop to work

  - by CS Student

  So I have a Tree<E> class where E is the datatype held and organized by the tree. I'd like to iterate through the Tree like this, or in a way similar to this: 1. Tree<String> tree=new Tree<String>(); 2. ...add some nodes... 3. for (String s : tree) 4. System.out.println(s); It gives me an error on line 3 though. Incompatible types required: java.lang.String found: java.lang.Object The following works fine and as expected though, performing a proper in-order traversal of the tree and printing each node out as it should: for (TreeIterator<String> i = tree.iterator(); i.hasNext(); ) System.out.println(i.next()); Any idea what I'm doing wrong? Do you need to see more of the code?

• Escaping colons in hibernate createSQLQuery

  - by Stratosgear

  I am confused on how I can create an SQL statement containing colons. I am trying to create a view and I am using (notice the double colons): create view MyView as ( SELECT tableA.colA as colA, tableB.colB as colB, round(tableB.colD / 1024)::numeric, 2) as calcValue, FROM tableA, tableB WHERE tableA.colC = 'someValue' ); This is a postgres query and I am forced to use the double colons (::) in order to correctly run the statement. I then pass the above statement through: s.createSQLQuery(myQuery).executeUpdate(); and I get a: Exception in thread "main" org.hibernate.exception.DataException: \ could not execute native bulk manipulation query at org.hibernate.exception.SQLStateConverter.convert(\ SQLStateConverter.java:102) ... more stacktrace... with an output of my above statement changed as (notice the question mark): create view MyView as ( SELECT tableA.colA as colA, tableB.colB as colB, round(tableB.colD / 1024)?, 2) as calcValue, FROM tableA, tableB WHERE tableA.colC = 'someValue' ); Obviously, hibernate confuses my colons with named parameters. Is there a way to escape the colons (a google suggestion that mentions that a single colon is escaped as a double colon does NOT work) or another way of running this statement? Thanks.
