• JQuery Div not animating in click function

  - by Doug

  Hi Everyone! I have the following code, I am attempting to have a div animate on a click event, but for some reason the div is immediately moving to the location and it's not animating to the coordinates specified, what am I doing wrong here? code: $(document).ready(function() { $('#example1').click(function(e){ var x = e.pageX - this.offsetLeft; var y = e.pageY - this.offsetTop; $('#example1-xy').html("X: " + x + " Y: " + y); var leftOfShip = x; //var leftOfShip = document.getElementById("ship").style.left + 20; $("#ship").animate({left: $("#ship").css("left",leftOfShip)},5000); }); }); Any Advice would be of help!!

• WPF List of ViewModels bound to list of Model objects.

  - by Eric

  In the model, I have: public ObservableCollection<Item> Items { get; private set; } In the ViewModel, I have a corresponding list of ItemViewModels: public ObservableCollection<ItemViewModel> ItemViewModels ... In the XAML, I will bind (in this case a TreeView) to the ItemViewModels property. My question is, what goes in the "..." in the ViewModel shown above? I am hoping for a line or two of code to binds these two ObservableCollections (providing the type of the ViewModel to construct for each model object). However, what I'm fearing is necessary is a bunch of code to handle the Items.CollectionChanged event and manually updates the ItemViewModels list by constructing ViewModels as necessary. Thanks! Eric

• Exception wrapping and HTML pages

  - by dotnetdev

  Hi, We have a sharepoint 2007 project at work. The exception handling policy is to log to the Sharepoint logs. In this case, would the best approach be to call that method and then rethrow the exception higher up? Except if I rethrow it to be caught higher up, there is no other exception handling code so what would happen in this case? Also, if you are going to display a more friendly error to the user (which uses information in the exception object), then this would be a good use of exception wrapping. Would it be a good idea to make a custom aspx page and add these to customerrors, so that on init (not sure of the exact event), I can display exception info in the passed parameter on the page. However, a static html page can't do this so I don't see the point in wrapping exceptions (unless there is a page or alert which uses the exception object). So if a project uses html pages for errors, is there a point in wrapping exceptions? Thanks

• UIWebView appears null when calling fro a method

  - by Alexidze

  I have a major problem when trying to access a UIWebView that was created during ViewDidLoad, the UIWebView appears null here is how i declare the property @property (nonatomic, retain) UIWebView *detailsView; the implementation @implementation iPadMainViewController @synthesize detailsView; - (void)viewDidLoad { [super viewDidLoad]; detailsView = [[UIWebView alloc] initWithFrame:CGRectMake(500, 0, 512, 768)]; [self.view addSubView:detailsView]; } When accessing from - (void)loadDetailedContent:(NSString *)s { NSLog(@"%@", detailsView); } I get NULL, is it a normal behavior or am i doing something wrong? here is the touchesBegan that is being called, from the views subclass that is being touched, -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { iPadMainViewController *mycontroller = [[iPadMainViewController alloc] init]; self.delegate = mycontroller; [self.delegate loadDetailedContent:NewsId]; }

• Does anybody have practice in programming PCMEF - architectures?

  - by Erkki

  PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?

• simulate to change the background color when click the link

  - by tom

  I have the following HTML and the java script below to simulate the background color change when the link block is clicked, but it doesn't seem to work. Any reason why? If I have only the onmousedown event handled, the background color will be changed to blue for sure. But if both onmousedown and onmouseup are handled, nothing would change visually. note... function changeColorOnMouseDown() { document.getElementById('note').style.background='blue'; } function changeColorOnMouseUp() { document.getElementById('note').style.background='#d8dde7'; }

• Java serial comm notifyOnDataAvailable configure receive buffer size?

  - by fred basset

  Hi All, I have a Java serial driver that's using the notifyOnDataAvailable mode to enable async. receive notification. I see an occasional problem where the SerialPortEvent.DATA_AVAILABLE serial event is not called until a relatively large no. of characters have been received (e.g. 34). The problem is that the sender sent a 20 byte packet, so the Java receiver did not send an ACK until the sender did a retry of the 20 byte send. Is there any way in Java COMM to configure the size of the receive buffer?

• how to exchange variables between extern iframe and site

  - by helle

  hey guys, for developement reasons (working with facebook-connect) i put the connect iframe in an iframe. on that way i am able to work on the connect-thing independent of my ip and don't have to develop on the live-server. the iframe holding the connect-button iframe is on my server, accessing the same db-server as the developer version (developer version is running on localhsot). as far as good ... BUT how can i let the parent site know, that the user has connected, so that i get his profile-picture displayd as reaction to this? how can i react in generally on an action/event/JS in an iframe? is there a way? can the iframe post data to the parent site? like a time-stamp and fb_userid? if the iframe stuff doesn't work ... i thougt of saving the ip to the fb_userid (to db) and check matches ... but i don't like this idea.

• embed multiple youtube videos to chromeless player cue

  - by Quaze

  So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

• Can events fired from an iframe be handled by elements in its parent?

  - by allyourcode

  Suppose I have a page located at www.example.com/foo, and it contains an iframe with src="http://www.example.com/bar". I want to be able to fire an event from /bar and have it be heard by /foo. Using the Prototype library, I've tried doing the following without success: Element.fire(parent, 'ns:frob'); When I do this, in ff 3.5, I get the following error: Node cannot be used in a document other than the one in which it was created" code: "4 Line 0 Not sure if that's related to my problem. Is there some security mechanism that's preventing scripts in /bar from kicking off events in /foo?

• Monitoring file upload progress in Actionscript 3

  - by helloworlder

  I'm trying to track the progress of a file upload in AS3, and I'm getting strange behavior. When I select a file and upload it, the progress is instantaneously 100% even if the file is 10 or more megabytes, but it's not finished. The onComplete event is fired about 30 second to a few minutes later (depending on file size) when the file has really finished uploading. I've tested this locally and on the server, the behaviour is the same. Has anyone else experienced this? Very frustrating ... Otherwise, the file is uploading fine. The code is simple: myFileReference.addEventListener(ProgressEvent.PROGRESS, onUploadProgress); function onUploadProgress(e:ProgressEvent) { var pctDone:Number = (e.bytesLoaded / e.bytesTotal) * 100; trace(pctDone); }

• Would this rollback/stop all records from inserting?

  - by chobo2

  Hi I been going through this tutorial http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx and them make a SP like this CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc Now my requirements require me to mass insert and mass update one after another. So first I am wondering can I merge those into one SP? I am not sure how it works with this OPENXML but I would think it would just be making sure that the XPath is right. Next what happens while it would be running this combined SP and something goes wrong. Would it roll back all the records or just stop and the records that happened before this event that crashed it would be inserted?

• jquery: Toggle elements based on result from a function

  - by Svish

  I have a number of table rows that I would like to toggle the visibility of. They should be visible if a data item I have set on them earlier equals a selected value in a form. This is what I have so far: $('#category-selector').change(function(event) { var category_id = $(this).val(); if(!category_id) { $('tr', '#table tbody').show(); } else { $('tr', '#table tbody').toggle(); } }); Of course this just toggles them on and off. Thing is that I thought I was able to give toggle a function that would decide if each row should be on or off, but it turns out I can only give it a boolean condition which would be an all or nothing deal kind of... So, I have this function: function() { return $(this).data('category_id') == category_id; } How can I use that to go through all the rows and toggle them on or off? Or is there a better approach to this? What should I do?

• The correct point in time to read an ASP .NET 1.1 control property in order to change page output

  - by RossMan

  Using ASP .NET 1.1 with CMS 2002 and C#. Trying to read the contents of a CMS HTML placeholder control into a string reader object so certain logic can be performed and the page output modified before it is displayed: StringReader srHtml = new StringReader(this.HtmlPlaceholderControl1.Html); The problem is that the Html property is empty during Page_Load, I've tried in a PreRender overload as well, but the property is still empty. The HtmlPlaceholder control does render html when the page load has completed. Which event should be handled in order to read the propery of the web control?

• Get text when enter is pressed in a text box in wxPython

  - by Sam

  I have a (single line) TextCtrl. The user types data into this. When they press enter, the contents of the box need to be extracted so they can be processed. I can't figure out how to catch enter being pressed. According to the docs, with the style wx.TE_PROCESS_ENTER set on my TextCtrl, it should generate a wx.EVT_COMMAND_TEXT_ENTER event when enter is pressed in the box, which I could then catch. However, wx.EVT_COMMAND_TEXT_ENTER seems not to exist (I get "module has no attribute EVT_COMMAND_TEXT_ENTER), so I'm a bit stuck. Googling just gets a couple of hits of people complaining wx.EVT_COMMAND_TEXT_ENTER doesn't work, so I guess I need another way of doing it.

• Handling download abort in PHP

  - by Aron Rotteveel

  Is it somehow possible to handle a download abort in PHP? In this specific case I am not speaking of a connection abort, but handling the event that triggers when the 'cancel' button in the browser download dialog button is clicked. Since this dialog already interprets the headers of the file that is to be download but does not actually start the download, it only seems logical there should be some way to catch this. Small (pseudo) code example to clear things up: // set some headers header('...'); // Question: what happens between the part where the headers are sent // and the actual data is being outputted to the client? IE: this is the part // where the download dialog should show up // Logical question that follows is: is there a way to detect a 'cancel'? $filename = '/some/file.txt'; $handle = fopen($filename, 'rb'); // output data to client while (!feof($handle)) { echo fread($handle, 8096); } fclose($handle);

• WCF: How to find out when a session is ending?

  - by TomTom

  I have a WCF application that is using sessions. Is there any central event to get thrown when a session ends? How can I find out when a session is ending WITHOUT (!) calling a method (network disconnect, client crashing - so no "logout" method call)? The server is hosted as: [ServiceBehavior( InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Reentrant, UseSynchronizationContext = false, IncludeExceptionDetailInFaults = true )] Basically because it is using a callback interface. Now, I basically need to decoubple the instance created from the backend store when the session terminates ;) Any ideas?

• How to get dataset to populate data into dbgrid in Delphi 6?

  - by Chris J

  I have created a DBGrid in Delphi 6 and tied it to a DataSource contained in a DataModule. The Dataset for that source in also located in the same module. In the OnShow event for the form, I activate the dataset and set a label equal to the rowcount for the dataset. This shows several hundred rows but nothing shows in the dbgrid. If I activate the dataset in the IDE, the grid populates with the expected data. Does anyone have any idea why this behaviour would change between the IDE and normal runtime? We are also using SDAC connection components. All 3rd party component choices are not mine to change. I can elaborate as necessary for clarification, but I mainly need troubleshooting ideas to start at.

• Put specific tds from a table row into edit using jQuery (then update w/ ajax)

  - by bbqsauced

  I'm somewhat new to jQuery, so I could use some help here. This is my issue: I have a php script outputting a dynamic table. Each row has an "edit" button, plus some other fields. Only 3 of those need to be turned into an input box. The edit button should only put that specific row into "edit mode." I got as far as assigning each row a unique class by adding a number to the end of it. I have been able to use jQuery to change all of the rows into edit mode, but I need it to be specific to a row. An example row would have classes like name0, price0, and desc0. The next row would go on to classes name1, price1, and desc1 (for the fields that need changed). How can I reference these values and pass them to jQuery so it processes an event on just those elements?
