  • How to change Jquery UI Slider handle

    - by Tom
    I want to modify the stock JQuery UI slider so that the handle has a arrow on it rather than being a square. i.e. I want to use a custom image as the handle. There are a few tutorials that do it: http://jqueryfordesigners.com/slider-gallery/ http://www.ryancoughlin.com/2008/11/04/using-the-jquery-ui-slider/ http://www.keepthewebweird.com/creating-a-nice-slider-with-jquery-ui/ But I can't get it to work. The following code results in a stationary handle image: <!DOCTYPE html> <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <style type="text/css"> #myhandle {position: absolute;z-index: 100;height: 25px;width: 35px;top: auto;background: url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat;} </style> <script type="text/javascript"> $(document).ready(function(){ $("#slider").slider({handle: '#myhandle'}); }); </script> </head> <body> <div id="slider"><div id="myhandle"></div></div> </body> </html> It is as if JQuery doesn't pick up that I want to use the myhandle id for the handle. I'm wondering: Do I need a plugin for JQuery to recognise the handle option? (it is not documented in http://docs.jquery.com/UI/Slider). Or perhaps it only worked in an old version of JQuery? Any ideas?

  • Cannot get UISearchBar Scope Bar to appear in Toolbar on iPad

    - by Jann
    This is really causing me fits. I put a toolbar on the IUView on the iPad. I added the following: Search Bar (not Search Bar and Search Display) to the toolbar. I set the options to be as follows: Show Cancel Button, Show Scope Bar, Scope Button Titles are: "Title1" and "Title2" (with Title2's radio button selected). Opaque, Clear Context and Auto Resize are checked. I hooked up the delegate of Search Bar to the "File's Owner" and linked it to IBOutlet theSearchBar. In my viewWillAppear I have the following: [theSearchBar setScopeButtonTitles:[NSArray arrayWithObjects:@"Near Me",@"Everywhere",nil]]; //Just in case: [theSearchBar setShowsScopeBar:YES]; //doesn't seem to do anything: //[theSearchBar sizeToFit]; searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:theSearchBar contentsController:self]; [self setSearchDisplayController:searchDisplayController]; [searchDisplayController setDelegate:self]; [searchDisplayController setSearchResultsDataSource:self]; //again--does not seem to do anything..but people have suggested it: [theSearchBar sizeToFit]; Okay, so far, I thought, so good. So, I made the File's Owner .m file to be a delegate for: UISearchBarDelegate, UISearchDisplayDelegate. My issue: I have yet to implement the delegates necessary to do the search but still... shouldn't I be seeing the scopeBar next to the search field when I click into the search field? Just so you know I DO see the log of the characters I type, so the delegate is working. I have the following dummy functions in the .m file (just in case) // called when keyboard search button pressed - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar { NSLog(@"Search Button Clicked\n"); [theSearchBar resignFirstResponder]; } // called when cancel button pressed - (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar { NSLog(@"Cancel Button Clicked\n"); [theSearchBar resignFirstResponder]; } - (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText { NSLog(@"Search Text So Far: '%@'\n",searchText); } - (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar { return YES; } - (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar { return YES; } Why doesn't the Scope Bar appear? A results UIPopoverController appears with the title "Results" and "No results found" (of course) when i type the first character in my search...but no scope bar. (not that i expect anything other than "No Results Found". I am wondering where the scope bar is supposed to appear...in the titleView of the UIPopover? In the toolbar to the right of the search area? Where?

  • Telerik Object reference not set to an instance of an object

    - by Duncan
    Hi, I have a main form which contains multiple worker threads. These threads raise events which update Telerik controls on the main form.

The application have a good internet connection and there is no problem reaching the app server-side api. I see in analytics that lots of startups and click-events the past few days are lost, even I know the traffic is normal since i can see statistics from the the server api. In the analytics reports I see a day by day under-reporting. So the problems seems to be spreading/growing to all the devices using this application. Im wondering why google does not answer this in their mail-groups - several people have complained about this...well, well... I found this thread relevant: http://stackoverflow.com/questions/682560/java-net-socketexception-broken-pipe But, I'm still not sure if there is anything I can do to fix it or not. If there is nothing I can do to fix it, I guess its not my fault that it got broken. But i got a feeling it is, since the problem got dramatically worse on the last deploy to Android market. Anyone else with experience on Google Analytics for android ?

  • Playing an InputStream video in Blackberry JDE.

    - by Jenny
    I think I'm using InputStream incorrectly with a Blackberry 9000 simulator: I found some sample code, http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/How%5FTo%5F-%5FPlay%5Fvideo%5Fwithin%5Fa%5FBlackBerry%5Fsmartphone%5Fapplication.html?nodeid=1383173&vernum=0 that lets you play video from within a Blackberry App. The code claims it can handle HTTP, but it's taken some fandangling to get it to actually approach doing so: http://pastie.org/609491 Specifically, I'm doing: StreamConnection s = null; s = (StreamConnection)Connector.open("http://10.252.9.15/eggs.3gp"); HttpConnection c = (HttpConnection)s; InputStream i = c.openInputStream(); System.out.println("~~~~~I have a connection?~~~~~~" + c); System.out.println("~~~~~I have a URL?~~~~" + c.getURL()); System.out.println("~~~~~I have a type?~~~~" + c.getType()); System.out.println("~~~~~I have a status?~~~~~~" + c.getResponseCode()); System.out.println("~~~~~I have a stream?~~~~~~" + i); player = Manager.createPlayer(i, c.getType()); I've found that this is the only way I can get an InputStream from an HTTPConnection without causing a: "JUM Error 104: Uncaught NullPointer Exception". (That is, the casting as a StreamConnection, and THEN as an HttpConnection stops it from crashing). However, I'm still not streaming video. Before, a stream wasn't able to be created (it would crash with the null pointer exception). Now, a stream is being made, the debugger claims it's begining to stream video from it...and nothing happens. No video plays. The app doesn't freeze, or crash or anything. I can 'pause' and 'play' freely, and get appropriate debug messages for both. But no video shows up. If I'm playing a video stored locally on the blackberry, everything is fine (it actually plays the video), so I know the Player itself is working fine, I"m just wondering if maybe I have something wrong with my stream? The API says the player can take in an InputStream. Is there a specific kind it needs? How can I query my inputstream to know if it's valid? It existing is further than I've gotten before. -Jenny Edit: I'm on a Blackberry Bold simulator (9000). I've heard that some versions of phones do NOT stream video via HTTP, however, the Bold does. I have yet to see examples of this though. When I go to the internet and point at a blackberry playable video, it attempts to stream, and then asks me to physically download the file (and then plays fine once I download). Edit: Also, I have a physical blackberry Bold, as well, but it can't stream either (I've gone to m.youtube.com, only to get a server/content not found error). Is there something special I need to do to stream RTSP content?

  • Eventlet or gevent or Stackless + Twisted, Pylons, Django and SQL Alchemy

    - by Khorkrak
    We're using Twisted extensively for apps requiring a great deal of asynchronous io. There are some cases where stuff is cpu bound instead and for that we spawn a pool of processes to do the work and have a system for managing these across multiple servers as well - all done in Twisted. Works great. The problem is that it's hard to bring new team members up to speed. Writing asynchronous code in Twisted requires a near vertical learning curve. It's as if humans just don't think that way naturally. We're considering a mixed approach perhaps. Maybe do the xmlrpc server part and process management in Twisted still but the other stuff in code that at least looks synchronous while not being as such. Then again I like explicit over implicit so hmmm. Anyway onto greenlets - how well does that stuff work? So there's Stackless and as you can see from my Gallentean avatar I'm well aware of the tremendous success in it's use for CCP's flagship EVE Online game first hand. What about Eventlet or gevent? Well for now only Eventlet works with Twisted. However gevent claims to be faster since it's not a pure python implementation it instead uses libevent. It also has fewer idiosyncrasies and defects supposedly. The documentation there is minimal in comparison to Eventlet and it's maintained by 1 guy as far as I can tell. This makes me leery but all great projects start this way so... Then there's PyPy - I haven't even finished reading about that one yet - just saw it in this thread: Drawbacks of Stackless. So confusing - I'm wondering what the heck to do - sounds like Eventlet is probably the best bet but is it really stable enough? Anyone out there have any experience with it? Should we go with Stackless instead as it's been around and is proven technology - just like Twisted is as well - and they do work together nicely. But still I hate having to have a separate version of Python to do this. what to do.... This somewhat obnoxious blog entry hit the nail on the head for me though: Asynchronous IO for Grownups We're stuck using MySQL as well - I never knew how great PostgreSQL was until having had to work on a production OLTP system in MySQL instead - but that's another story. But if that monkey patch thing really works then wow. Just wow.

  • Building the DropThings ASP.NET Solution

    - by Sephrial
    Hi all, I'm attempting to build a project called DropThings but I am getting all these errors and I'm not sure how to resolve them. Can anyone lend a helping hand?

  • JQuery dialog momentairly displayed on page load

    - by Kevin Won
    I created a page that has a JQuery based dialog using the standard JQuery UI function. I do this with out of the box functionality of JQuery... nothing special at all. Here is my HTML for the dialog: <div id = "myDialog"> <!-- ... more html in here for the dialog --> </div> Then the JQuery called in javascript that transforms the <div> to a dialog: // pruned .js as an example of kicking up a JQuery dialog $('#myDialog').dialog({ autoOpen: false, title: 'Title here', modal: true } }); Again, plain-vanilla JQuery. So you start this wizard by clicking on a link on the parent page, and it then spawns a JQuery dialog which has a significant chunk of HTML that includes images, etc. As I continued developing this page, I started to notice that when I loaded the page in the browser that the <div> tags I was putting in that JQuery transforms into dialogs would very briefly be displayed. Then the page would act as expected. In other words, the dialog would not be hidden, it would be displayed briefly in-line in the page. Quite ugly and unprofessional looking! But after a split second, the page would render correctly and look just as I expected/wanted. Over time, as the page size grew, the time the page would remain incorrectly rendered grew. My guess is that the rendering engine of the browser is rendering the page as it is loading, then at the end it is kicking off the JQuery that will transform the <div> into a dialog. This JQuery function will then transform the simple <div> to a JQuery dialog and hide it (since I have the autoOpen property set to false). Some browsers <cough>IE</cough> display it longer than others. My large-ish dialog now causes the page to incorrectly render for about 1 second... YUCK! I came up with a resolution to this problem which works OK, but I'm wondering if someone knows of a better way.

  • Single Sign On for a Web App

    - by Jeremy Goodell
    I have been trying to understand how this problem is solved for over a month now. I really need to come up with a general approach that works -- I'm basically the only resource who can do it. I have a theory, but I'm just not sure it's the easiest (or correct) approach and I haven't been able to find any information to support my ideas. Here's the scenario: 1) You have a complex web application that offers secure content on a subscription basis. 2) Users are required to log in to your application with user name and password. 3) You sell to large corporations, which already have a corporate authentication technology (for example, Active Directory). 4) You would like to integrate with the corporate authentication mechanism to allow their users to log onto your Web App without having to enter their user name and password. Now, any solution you come up with will have to provide a mechanism for: adding new users removing users changing user information allowing users to log in Ideally, all these would happen "automagically" when the corporate customer made the corresponding changes to their own authentication. Now, I have a theory that the way to do this (at least for Active Directory) would be for me to write a client-side app that integrates with the customer's Active Directory to track the targeted changes, and then communicate those changes to my Web App. I think that if this communication were done via Web Services offered by my web app, then it would maintain an unhackable level of security, which would obviously be a requirement for these corporate customers. I've found some information about a Microsoft product called Active Directory Federation Service (ADFS) which may or may not be the right approach for me. It seems to be a bit bulky and have some requirements that might not work for all customers. For other existing ID scenarios (like Athens and Shibboleth), I don't think a client application is necessary. It's probably just a matter of tying into the existing ID services. I would appreciate any advice anyone has on anything I've mentioned here. In particular, if you can tell me if my theory is correct about providing a client-side app that communicates with server-side Web Services, or if I'm totally going in the wrong direction. Also, if you could point me at any web sites or articles that explain how to do this, I'd really appreciate it. My research has not turned up much so far. Finally, if you could let me know of any Web applications that currently offer this service (particularly as tied to a corporate Active Directory), I would be very grateful. I am wondering if other B2B Web app's like salesforce.com, or hoovers.com offer a similar service for their corporate customers. I hate being in the dark and would greatly appreciate any light you can shed ... Jeremy

  • Uploadify Hanging at random on 100%

    - by Matty
    I am using Uploadify (http://www.uploadify.com/) to enable my users to upload images via my web application. The problem I am having is that every now and then (at what appears to be random) when the progress bar reaches 100% it 'hangs' and does nothing. I was wondering if any developers familiar with uploadify may have any idea how to solve this? I am in desperate need of some help. Here is my front-end code: jQuery(document).ready(function() { jQuery("#uploadify").uploadify({ 'uploader' : 'javascripts/uploadify.swf', 'script' : 'upload-file2.php', 'cancelImg' : 'css/images/cancel.png', 'folder' : 'uploads/personal_images/' + profileOwner, 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'fileDesc' : 'Image files', 'fileExt' : '.jpg;.jpeg;.gif;.png', 'sizeLimit' : '2097152', 'onComplete': function(event, queueID, fileObj, response, data) { processPersonalImage(fileObj.name); arrImgNames.push(fileObj.name); showUploadedImages(true); document.getElementById("photos").style.backgroundImage = "url('css/images/minicam.png')"; }, 'onAllComplete' : function() { completionMessage(arrFailedNames); document.getElementById("displayImageButton").style.display = "inline"; document.getElementById("photos").style.backgroundImage = "url('css/images/minicam.png')"; }, 'onCancel' : function() { arrImgNames.push(fileObj.name); arrFailedNames.push(fileObj.name); showUploadedImages(false); }, 'onError' : function() { arrImgNames.push(fileObj.name); arrFailedNames.push(fileObj.name); showUploadedImages(false); } }); }); And server side: if (!empty($_FILES)) { //Get user ID from the file path for use later.. $userID = getIdFromFilePath($_REQUEST['folder'], 3); $row = mysql_fetch_assoc(getRecentAlbum($userID, "photo_album_personal")); $subFolderName = $row['pk']; //Prepare target path / file.. $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'.$subFolderName.'/'; $targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name']; //Move uploaded file from temp directory to new folder move_uploaded_file($tempFile,$targetFile); //Now add a record to DB to reflect this personal image.. if(file_exists($targetFile)) { //add photo record to DB $directFilePath = $_REQUEST['folder'] . '/'.$subFolderName.'/' . $_FILES['Filedata']['name']; addPersonalPhotoRecordToDb($directFilePath, $row['pk']); } echo "1"; die(true); } thanks for any help!!

  • IE7 relative/absolute positioning bug with dynamically modified page content

    Hi, I was wondering if there's anyone having an idea how to tackle with the following problem in IE7: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>IE7 absolute positioning bug</title> <style type="text/css"> #panel { position: relative; border: solid 1px black; } #spacer { height: 100px; } #footer { position: absolute; bottom: 0px; } </style> <script type="text/javascript"> function toggle() { var spacer = document.getElementById("spacer"); var style = "block"; if (spacer.style.display == "block" || spacer.style.display == "") { style = "none"; } spacer.style.display = style; } </script> </head> <body> <div id="panel"> <button onclick="toggle();">Click me</button> <br /><br /><br /> <div id="spacer"></div> <div id="footer">This is some footer</div> </div> </body> </html> When you run this in IE7 you'll see that the "footer" element stays after modifying the CSS for "panel". The same example tested in IE8, FF and Chrome behaves exactly as expected. I've already tried updating the element's class but this does not work if the browser's window has been opened maximized and no further size changes were made to the window (which is about 90% of the use cases we have for our product.... :( ) I'm stuck with a CSS-based solution however I think that I can make an exception in this case if it can easily be made IE7-specific (which means that other browsers will behave in a standard way with this). Please help!

  • Testing Django Inline ModelForms: How to arrange POST data?

    - by unclaimedbaggage
    Hi folks, I have a Django 'add business' view which adds a new business with an inline 'business_contact' form. The form works fine, but I'm wondering how to write up the unit test - specifically, the 'postdata' to send to self.client.post(settings.BUSINESS_ADD_URL, postdata) I've inspected the fields in my browser and tried adding post data with corresponding names, but I still get a 'ManagementForm data is missing or has been tampered with' error when run. Anyone know of any resources for figuring out how to post inline data? Relevant models, views & forms below if it helps. Lotsa thanks. MODEL: class Contact(models.Model): """ Contact details for the representatives of each business """ first_name = models.CharField(max_length=200) surname = models.CharField(max_length=200) business = models.ForeignKey('Business') slug = models.SlugField(max_length=150, unique=True, help_text=settings.SLUG_HELPER_TEXT) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) phone = models.CharField(max_length=100, null=True, blank=True) mobile_phone = models.CharField(max_length=100, null=True, blank=True) email = models.EmailField(null=True) deleted = models.BooleanField(default=False) class Meta: db_table='business_contact' def __unicode__(self): return '%s %s' % (self.first_name, self.surname) @models.permalink def get_absolute_url(self): return('business_contact', (), {'contact_slug': self.slug }) class Business(models.Model): """ The business clients who you are selling products/services to """ business = models.CharField(max_length=255, unique=True) slug = models.SlugField(max_length=100, unique=True, help_text=settings.SLUG_HELPER_TEXT) description = models.TextField(null=True, blank=True) primary_contact = models.ForeignKey('Contact', null=True, blank=True, related_name='primary_contact') business_type = models.ForeignKey('BusinessType') deleted = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) address_1 = models.CharField(max_length=255, null=True, blank=True) address_2 = models.CharField(max_length=255, null=True, blank=True) suburb = models.CharField(max_length=255, null=True, blank=True) city = models.CharField(max_length=255, null=True, blank=True) state = models.CharField(max_length=255, null=True, blank=True) country = models.CharField(max_length=255, null=True, blank=True) phone = models.CharField(max_length=40, null=True, blank=True) website = models.URLField(null=True, blank=True) class Meta: db_table = 'business' def __unicode__(self): return self.business def get_absolute_url(self): return '%s%s/' % (settings.BUSINESS_URL, self.slug) VIEWS: class Contact(models.Model): """ Contact details for the representatives of each business """ first_name = models.CharField(max_length=200) surname = models.CharField(max_length=200) business = models.ForeignKey('Business') slug = models.SlugField(max_length=150, unique=True, help_text=settings.SLUG_HELPER_TEXT) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) phone = models.CharField(max_length=100, null=True, blank=True) mobile_phone = models.CharField(max_length=100, null=True, blank=True) email = models.EmailField(null=True) deleted = models.BooleanField(default=False) class Meta: db_table='business_contact' def __unicode__(self): return '%s %s' % (self.first_name, self.surname) @models.permalink def get_absolute_url(self): return('business_contact', (), {'contact_slug': self.slug }) class Business(models.Model): """ The business clients who you are selling products/services to """ business = models.CharField(max_length=255, unique=True) slug = models.SlugField(max_length=100, unique=True, help_text=settings.SLUG_HELPER_TEXT) description = models.TextField(null=True, blank=True) primary_contact = models.ForeignKey('Contact', null=True, blank=True, related_name='primary_contact') business_type = models.ForeignKey('BusinessType') deleted = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) address_1 = models.CharField(max_length=255, null=True, blank=True) address_2 = models.CharField(max_length=255, null=True, blank=True) suburb = models.CharField(max_length=255, null=True, blank=True) city = models.CharField(max_length=255, null=True, blank=True) state = models.CharField(max_length=255, null=True, blank=True) country = models.CharField(max_length=255, null=True, blank=True) phone = models.CharField(max_length=40, null=True, blank=True) website = models.URLField(null=True, blank=True) class Meta: db_table = 'business' def __unicode__(self): return self.business def get_absolute_url(self): return '%s%s/' % (settings.BUSINESS_URL, self.slug) FORMS: class AddBusinessForm(ModelForm): class Meta: model = Business exclude = ['deleted','primary_contact',] class ContactForm(ModelForm): class Meta: model = Contact exclude = ['deleted',] AddBusinessFormSet = inlineformset_factory(Business, Contact, can_delete=False, extra=1, form=AddBusinessForm, )

  • How to convert an NSArray of NSManagedObjects to NSData

    - by carok
    Hi, I'm new to Objective C and was wondering if anyone can help me. I am using core data with a sqlite database to hold simple profile objects which have a name and a score attribute (both of which are of type NSString). What I want to do is fetch the profiles and store them in an NSData object, please see my code below: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"GamerProfile" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES]; NSArray *sortDecriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDecriptors]; [sortDescriptor release]; [sortDecriptors release]; NSError *error; NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; NSData *data = [NSKeyedArchiver archivedDataWithRootObject:items]; [self SendData:data]; [fetchRequest release]; When I run the code I'm getting the error "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[GamerProfile encodeWithCoder:]: unrecognized selector sent to instance 0x3f4b530'" I presume I have to add an encodeWithCoderClass to my core data NSManagedObject object (GamerProfile) but I'm not sure how to do this even after reading the documentation, My attempt at doing this is below. I'm not sure if I'm going along the right lines with this as get a warning stating "NSManagedObject" may not respond to '-encodeWithCoder'" I would really, really appreciate it if someone could point me in the right direction!! Thanks C Here is the code for my GamerProfile (CoreData NSManagedObject Object) with my attempt at adding an encodeWithCoder method... Header File #import <CoreData/CoreData.h> @interface GamerProfile : NSManagedObject <NSCoding> { } @property (nonatomic, retain) NSString * GamerScore; @property (nonatomic, retain) NSString * Name; - (void)encodeWithCoder:(NSCoder *)coder; @end Code File #import "GamerProfile.h" @implementation GamerProfile @dynamic GamerScore; @dynamic Name; - (void)encodeWithCoder:(NSCoder *)coder { [super encodeWithCoder:coder]; [coder encodeObject:GamerScore forKey:@"GamerScore"]; [coder encodeObject:Name forKey:@"Name"]; }

  • Pass or Get a value from Parent ViewModel down to Sub-ViewModel?

    - by mkmurray
    I am using the MVVM Light framework as well as Unity for DI. I have some nested Views, each bound to a corresponding ViewModel. The ViewModels are bound to each View's root control DataContext via the ViewModelLocator idea that Laurent Bugnion has put into MVVM Light. This allows for finding ViewModels via a static resource and for controlling the lifetime of ViewModels via a Dependency Injection framework, in this case Unity. It also allows for Expression Blend to see everything in regard to ViewModels and how to bind them. As I stated the Views have a healthy dose of nesting, but the ViewModels don't really know anything about each other. A parent view binds to its corresponding ViewModel via the static resource ViewModelLocator (which uses Unity to control the construction and lifetime of the ViewModel object). That parent view contains a user control in it that is another sub-view, which then goes and gets its corresponding ViewModel via the ViewModelLocator as well. The ViewModels don't have references to each other or know any hierarchy in regard to each other. So here's an example of how the ViewModels do interact via messaging. I've got a parent View that has a ComboBox databound to an ObservableCollection in its ViewModel. The ComboBox's SelectedItem is also bound (two-way) to a property on the ViewModel. When the selection of the ComboBox changes, this is to trigger updates in other Views and sub-Views. Currently I am accomplishing this via the Messaging system that is found in MVVM Light. So I'm wondering what the best practice would be to get information from one ViewModel to another? In this case, what I need to pass down to sub-ViewModels is basically a user Guid representing the currently logged in user. The top-most parent View (well, ViewModel) will know this information, but I'm not sure how to get it down into the sub-ViewModels. Some possible approaches I can think of: Should the sub-ViewModel ask the static resource ViewModelLocator for a reference to the same object the parent View is using and access the property that way? It seems like ViewModels going through each other's properties is not very clean and couples them together unnecessarily. I'm already using messaging to notify the sub-Views that the user selected a new item in the ComboBox and to update accordingly. But the object type that is being selected in the ComboBox is not really directly related to this data value that the sub-Views need.

  • Messing with Encoding and XslCompiledTransform

    - by Josemalive
    Hello, im messing with the encodings. For one hand i have a url that is responding me in UTF-8 (im pretty sure thanks to firebug plugin). Im opening the url reading the content in UTF-8 using the following code: StreamReader reader = new StreamReader(response.GetResponseStream(),System.Text.Encoding.UTF8); For other hand i have a transformation xslt sheet with the following code: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"> <xsl:output method="xml" indent="yes"/> <xsl:template match="@* | node()"> <xsl:copy> <xsl:apply-templates select="@* | node()"/> <br/> hello </xsl:copy> </xsl:template> </xsl:stylesheet> This xslt sheet is saved in UTF-8 format too. I use the following code to mix the xml with the xslt: StringWriter writer = new StringWriter(); XslCompiledTransform transformer = new XslCompiledTransform(); transformer.Load(HttpContext.Current.Server.MapPath("xslt\\xsltsheet.xslt"); XmlWriterSettings xmlsettings = new XmlWriterSettings(); xmlsettings.Encoding = System.Text.Encoding.UTF8; transformer.Transform(xmlreader, null, writer); return writer; Then after all im render in the webbrowser the content of this writer and im getting the following error: The XML page cannot be displayed Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later. Switch from current encoding to specified encoding not supported. Error processing resource 'http://localhost:2541/Results.... <?xml version="1.0" encoding="utf-16"?> Im wondering where is finding the UTF-16 encoding take in count that: All my files are saved as UTF-8 The response from the server is in UTF-8 The way of read the xslt sheet is configured as UTF-8.

  • Can't get tokens when using OAuth with LinkedIn API

    - by Angela
    Hi, was wondering if anyone can help me to get this basic OAuth implementation to work using the LinkedIn API: The output for the indexes oauth_token and oauth_token_secret are blank. The file I refer to in OAuth.php are a set of classes to help generate the token requests and tokens. That file is here: http://www.easy-share.com/1909603316/OAuth.php <?php session_start(); require_once("OAuth.php"); $app_token = "YOUR APP TOKEN GOES HERE"; $app_key = "YOUR APP KEY GOES HERE"; $domain = "https://api.linkedin.com/uas/oauth"; $sig_method = new OAuthSignatureMethod_HMAC_SHA1(); $test_consumer = new OAuthConsumer($app_token, $app_key, NULL); $callback = "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?action=getaccesstoken"; # First time through, get a request token from LinkedIn. if (!isset($_GET['action'])) { $req_req = OAuthRequest::from_consumer_and_token($test_consumer, NULL, "POST", $domain .

  • T-SQL selecting values that match ISNUMERIC and also are within a specified range. (plus Linq-to-sql

    - by Toby
    I am trying to select rows from a table where one of the (NVARCHAR) columns is within a numeric range. SELECT ID, Value FROM Data WHERE ISNUMERIC(Value) = 1 AND CONVERT(FLOAT, Value) < 66.6 Unfortunately as part of the SQL spec the AND clauses don't have to short circuit (and don't on MSSQL Server EE 2008). More info: http://stackoverflow.com/questions/789231/is-the-sql-where-clause-short-circuit-evaluated My next attempt was to try this to see if I could achieve delayed evaluation of the CONVERT SELECT ID, Value FROM Data WHERE (CASE WHEN ISNUMERIC(Value) = 1 THEN CONVERT(FLOAT, Value) < 66.6 ELSE 0 END) but I cannot seem to use a < (or any comparison) with the result of a CONVERT. It fails with the error Incorrect syntax near '<'. I can get away with SELECT ID, CONVERT(FLOAT, Value) AS Value FROM Data WHERE ISNUMERIC(Value) = 1 So the obvious solution is to wrap the whole select statement in another SELECT and WHERE and return the converted values from the inner select and filter in there where of the outer select. Unfortunately this is where my Linq-to-sql problem comes in. I am filtering not only by one range but potentialy by many, or just by the existance of the record (there are some date range selects and comparisons I've left out.) Essentially I would like to be able to generate something like this: SELECT ID, TypeID, Value FROM Data WHERE (TypeID = 4 AND ISNUMERIC(Value) AND CONVERT(Float, Value) < 66.6) OR (TypeID = 8 AND ISNUMERIC(Value) AND CONVERT(Float, Value) > 99) OR (TypeID = 9) (With some other clauses in each of those where options.) This clearly doesn't work if I filter out the non-ISNUMERIC values in an inner select. As I mentioned I am using Linq-to-sql (and PredicateBulider) to build up these queries but unfortunately Datas.Where(x => ISNUMERIC(x.Value) ? Convert.ToDouble(x.Value) < 66.6 : false) Gets converted to this which fails the initial problem. WHERE (ISNUMERIC([t0].[Value]) = 1) AND ((CONVERT(Float,[t0].[Value])) < @p0) My last resort will have to be to outer join against a double select on the same table for each of the comparisons but this isn't really an idea solution. I was wondering if anyone has run into similar issues before?

  • Handling Model Inheritance in ASP.NET MVC2 & NHibernate

    - by enth
    I've gotten myself stuck on how to handle inheritance in my model when it comes to my controllers/views. Basic Model: public class Procedure : Entity { public Procedure() { } public int Id { get; set; } public DateTime ProcedureDate { get; set; } public ProcedureType Type { get; set; } } public ProcedureA : Procedure { public double VariableA { get; set; } public int VariableB { get; set; } public int Total { get; set; } } public ProcedureB : Procedure { public int Score { get; set; } } etc... many of different procedures eventually. So, I do things like list all the procedures: public class ProcedureController : Controller { public virtual ActionResult List() { IEnumerable<Procedure> procedures = _repository.GetAll(); return View(procedures); } } but now I'm kinda stuck. Basically, from the list page, I need to link to pages where the specific subclass details can be viewed/edited and I'm not sure what the best strategy is. I thought I could add an action on the ProcedureController that would conjure up the right subclass by dynamically figuring out what repository to use and loading the subclass to pass to the view. I had to store the class in the ProcedureType object. I had to create/implement a non-generic IRepository since I can't dynamically cast to a generic one. public virtual ActionResult Details(int procedureID) { Procedure procedure = _repository.GetById(procedureID, false); string className = procedure.Type.Class; Type type = Type.GetType(className, true); Type repositoryType = typeof (IRepository<>).MakeGenericType(type); var repository = (IRepository)DependencyRegistrar.Resolve(repositoryType); Entity procedure = repository.GetById(procedureID, false); return View(procedure); } I haven't even started sorting out how the view is going to determine which partial to load to display the subclass details. I'm wondering if this is a good approach? This makes determining the URL easy. It makes reusing the Procedure display code easy. Another approach is specific controllers for each subclass. It simplifies the controller code, but also means many simple controllers for the many procedure subclasses. Can work out the shared Procedure details with a partial view. How to get to construct the URL to get to the controller/action in the first place? Time to not think about it. Hopefully someone can show me the light. Thanks in advance.

  • DynamicMethod for ConstructorInfo.Invoke, what do I need to consider?

    - by Lasse V. Karlsen
    My question is this: If I'm going to build a DynamicMethod object, corresponding to a ConstructorInfo.Invoke call, what types of IL do I need to implement in order to cope with all (or most) types of arguments, when I can guarantee that the right type and number of arguments is going to be passed in before I make the call? Background I am on my 3rd iteration of my IoC container, and currently doing some profiling to figure out if there are any areas where I can easily shave off large amounts of time being used. One thing I noticed is that when resolving to a concrete type, ultimately I end up with a constructor being called, using ConstructorInfo.Invoke, passing in an array of arguments that I've worked out. What I noticed is that the invoke method has quite a bit of overhead, and I'm wondering if most of this is just different implementations of the same checks I do. For instance, due to the constructor matching code I have, to find a matching constructor for the predefined parameter names, types, and values that I have passed in, there's no way this particular invoke call will not end up with something it should be able to cope with, like the correct number of arguments, in the right order, of the right type, and with appropriate values. When doing a profiling session containing a million calls to my resolve method, and then replacing it with a DynamicMethod implementation that mimics the Invoke call, the profiling timings was like this: ConstructorInfo.Invoke: 1973ms DynamicMethod: 93ms This accounts for around 20% of the total runtime of this profiling application. In other words, by replacing the ConstructorInfo.Invoke call with a DynamicMethod that does the same, I am able to shave off 20% runtime when dealing with basic factory-scoped services (ie. all resolution calls end up with a constructor call). I think this is fairly substantial, and warrants a closer look at how much work it would be to build a stable DynamicMethod generator for constructors in this context. So, the dynamic method would take in an object array, and return the constructed object, and I already know the ConstructorInfo object in question. Therefore, it looks like the dynamic method would be made up of the following IL: l001: ldarg.0 ; the object array containing the arguments l002: ldc.i4.0 ; the index of the first argument l003: ldelem.ref ; get the value of the first argument l004: castclass T ; cast to the right type of argument (only if not "Object") (repeat l001-l004 for all parameters, l004 only for non-Object types, varying l002 constant from 0 and up for each index) l005: newobj ci ; call the constructor l006: ret Is there anything else I need to consider? Note that I'm aware that creating dynamic methods will probably not be available when running the application in "reduced access mode" (sometimes the brain just won't give up those terms), but in that case I can easily detect that and just calling the original constructor as before, with the overhead and all.

  • NTRU Pseudo-code for computing Polynomial Inverses

How should i implement that line in my code. Can someone give me an example. The above algorithm is for computing Inverse polynomials for NTRUEncrypt key generation. The pseudo-code can be found on page 28 of this document. Thanks in advance.

  • Doubt about adopting CI (Hudson) into an existing automated Build Process (phing, svn)

    - by maraspin
    OUR CURRENT BUILD PROCESS We're a small team of developers (2 to 4 people depending on project) who currently use Phing to deploy code to a staging environment, before going live. We keep our code in a SVN repo, where the trunk holds current active development and, at certain times, we do make branches that we test and then (if successful), tag and export to the staging env. If everything goes well there too, we finally deploy'em in production servers. Actions are highly automated, but always triggered by human intervention. THE DOUBT We'd now like to introduce Continuous Integration (with Hudson) in the process; unfortunately we have a few doubts about activity syncing, since we're afraid that CI could somewhat interfere with our build process and cause certain problems. Considering that an automated CI cycle has a certain frequency of automatically executed actions, we in fact only see 2 possible cases for "integration", each with its own problems: Case A: each CI cycle produces a new branch with its own name; we do use such a name to manually (through phing as it happens now) export the code from the SVN to the staging env. The problem I see here is that (unless specific countermeasures are taken) the number of branches we have can grow out of control (let's suppose we commit often, so that we have a fresh new build/branch every N minutes). Case B: each CI cycle creates a new branch named 'current', for instance, which is tagged with a unique name only when we manually decide to export it to staging; the current branch, at any case is then deleted, as soon as the next CI cycle starts up. The problem we see here is that a new cycle could kick in while someone is tagging/exporting the 'current' branch to staging thus creating an inconsistent build (but maybe here I'm just too pessimist, since I confess I don't know whether SVN offers some built-in protection against this). With all this being said, I was wondering if anyone with similar experiences could be so kind to give us some hints on the subject, since none of the approaches depicted above looks completely satisfing to us. Is there something important we just completely left off in the overall picture? Thanks for your attention &, in advance, for your help!

  • C# SerialPort - Problems mixing ports with different baud rates.

    - by GrandAdmiral
    Greetings, I have two devices that I would like to connect over a serial interface, but they have incompatible connections. To get around this problem, I connected them both to my PC and I'm working on a C# program that will route traffic on COM port X to COM port Y and vice versa. The program connects to two COM ports. In the data received event handler, I read in incoming data and write it to the other COM port. To do this, I have the following code: private void HandleDataReceived(SerialPort inPort, SerialPort outPort) { byte[] data = new byte[1]; while (inPort.BytesToRead > 0) { // Read the data data[0] = (byte)inPort.ReadByte(); // Write the data if (outPort.IsOpen) { outPort.Write(data, 0, 1); } } } That code worked fine as long as the outgoing COM port operated at a higher baud rate than the incoming COM port. If the incoming COM port was faster than the outgoing COM port, I started missing data. I had to correct the code like this: private void HandleDataReceived(SerialPort inPort, SerialPort outPort) { byte[] data = new byte[1]; while (inPort.BytesToRead > 0) { // Read the data data[0] = (byte)inPort.ReadByte(); // Write the data if (outPort.IsOpen) { outPort.Write(data, 0, 1); while (outPort.BytesToWrite > 0); //<-- Change to fix problem } } } I don't understand why I need that fix. I'm new to C# (this is my first program), so I'm wondering if there is something I am missing. The SerialPort defaults to a 2048 byte write buffer and my commands are less than ten bytes. The write buffer should have the ability to buffer the data until it can be written to a slower COM port. In summary, I'm receiving data on COM X and writing the data to COM Y. COM X is connected at a faster baud rate than COM Y. Why doesn't the buffering in the write buffer handle this difference? Why does it seem that I need to wait for the write buffer to drain to avoid losing data? Thanks!

    For those interested, I have now modified the SubSonic 2.x code to recognize and support DataTable parameter types. You can read more about SQL Server 2008 features here: http://download.microsoft.com/download/4/9/0/4906f81b-eb1a-49c3-bb05-ff3bcbb5d5ae/SQL%20SERVER%202008-RDBMS/T-SQL%20Enhancements%20with%20SQL%20Server%202008%20-%20Praveen%20Srivatsav.pdf What this enhancement will now allow you to do is to create a partial StoredProcedures.cs class, with a method that overrides the stored procedure wrapper method. A bit about good form: My DAL has no direct table access, and my DB only has execute permissions for that user to my sprocs. As such, SubSonic only generates the AllStructs and StoredProcedures classes. The SPROC: ALTER PROCEDURE [dbo].[testInsertToTestTVP] @UserDetails TestTVP READONLY, @Result INT OUT AS BEGIN SET NOCOUNT ON; SET @Result = -1 --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] ON INSERT INTO [dbo].[tbl_TestTVP] ( [GroupInsertID], [FirstName], [LastName] ) SELECT [GroupInsertID], [FirstName], [LastName] FROM @UserDetails IF @@ROWCOUNT > 0 BEGIN SET @Result = 1 SELECT @Result RETURN @Result END --SET IDENTITY_INSERT [dbo].[tbl_TestTVP] OFF END The TVP: CREATE TYPE [dbo].[TestTVP] AS TABLE( [GroupInsertID] [varchar](50) NOT NULL, [FirstName] [varchar](50) NOT NULL, [LastName] [varchar](50) NOT NULL ) GO The the auto gen tool runs, it creates the following erroneous method: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(string UserDetails, int? Result) { SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); sp.Command.AddParameter("@UserDetails", UserDetails, DbType.AnsiString, null, null); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } It sets UserDetails as type string. As it's good form to have two folders for a SubSonic DAL - Custom and Generated, I created a StoredProcedures.cs partial class in Custom that looks like this: /// <summary> /// Creates an object wrapper for the testInsertToTestTVP Procedure /// </summary> public static StoredProcedure TestInsertToTestTVP(DataTable dt, int? Result) { DataSet ds = new DataSet(); SubSonic.StoredProcedure sp = new SubSonic.StoredProcedure("testInsertToTestTVP", DataService.GetInstance("MyDAL"), "dbo"); // TODO: Modify the SubSonic code base in sp.Command.AddParameter to accept // a parameter type of System.Data.SqlDbType.Structured, as it currently only accepts // System.Data.DbType. //sp.Command.AddParameter("@UserDetails", dt, System.Data.SqlDbType.Structured null, null); sp.Command.AddParameter("@UserDetails", dt, SqlDbType.Structured); sp.Command.AddOutputParameter("@Result", DbType.Int32, 0, 10); return sp; } As you can see, the method signature now contains a DataTable, and with my modification to the SubSonic framework, this now works perfectly. I'm wondering if the SubSonic guys can modify the auto-gen to recognize a TVP in a sproc signature, as to avoid having to re-write the warpper? Does SubSonic 3.x support Structured data types? Also, I'm sure many will be interested in using this code, so where can I upload the new code? Thanks.

  • Get the string representation of a jquery DOM object's entire HTML

    - by Scozzard
    Hi, I have had a bit of a look around and am having some difficulty solving a wee issue I am having. I basically have a string of HTML, I convert that to a JQuery DOM object so that I can easily remove all elements that have a certain class using JQuery's .remove(). I.e., var radHtml = editor.get_html(); var jqDom = $(radHtml); $(".thickbox", jqDom).remove(); $(".thickboxcontent", jqDom).remove(); editor.set_html(this.innerHTML); NOTE: The HTML is derived from content in a RADEditor text editor so there are no parent HTML tags, so can look as follows: <p>This is a header</p> <p>this is some content followed by a table </p> <a href="#TB_inline?height=350&amp;width=400&amp;inlineId=myOnPageContent0" class="thickbox">Test Thickbox</a> <div id="myOnPageContent0" class="thickboxcontent"> <table class="modal"> <thead> </thead> <tbody> <tr> <td>item</td> <td>result</td> </tr> <tr> <td>item 1</td> <td>1</td> </tr> <tr> <td>item 2</td> <td>2</td> </tr> <tr> <td>item 3</td> <td>3</td> </tr> </tbody> </table> </div> Here is what the jqDom.html() returns from the HTML above: "This is a header" I was wondering if there was an easy way to do this - have some html and remove all elements (in this case divs) that have a certain class (but leaving their contents). JQuery doesnt have to used, but I would like to. Manipulating the DOM object is fine - it is getting the full DOM object in its entirety as a string that I am having the problem with. Any help would be much appreicated. Thanks.

  • Problem adding subviews (UIButtons) to subclass of UIImageView

    - by samfu_1
    I'm adding a custom button/keypad to my application. Thus far, I have a UIImageView subclass that contains an animation that slides it from the bottom of the screen, and then back down when the user no longer needs it. I'm having trouble adding UIButtons to this UIImageView, however. Since this is a subclass of UIView, I'm attempting to add buttons to my view via the initWithFrame: method. (slideDown method is the added animation) in my UIImageView Subclass, I have a UIButton ivar object added: -(id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame: frame]) { UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect]; button.frame = CGRectMake(16.0, 20.0, 50.0, 50.0); [button setTitle: @"Go" forState: UIControlStateNormal]; [button addTarget: self action: @selector(slideDown) forControlEvents: UIControlEventTouchUpInside]; self.button1 = button; [self addSubview: button1]; NSLog(@"Button added"); } return self; } In my view controller, I instantiate my UIIMageView Subclass in the -(void)viewDidLoad: method as follows: -(void)viewDidLoad { //other objects init'ed ButtonPad *customPad = [[ButtonPad alloc] initWithImage: [UIImage imageNamed: @"ButtonPad.png"]]; customPad.frame = CGRectMake(0.0, 480.0, 320.0, 300.0); self.buttonPad = customPad; [self.view addSubview: buttonPad]; [customPad release]; [super viewDidLoad]; } My current app allows the view to slide up and down off of the screen without any problems. However, the button never appears. I have also tried adding the button to my buttonPad object by instantiating & adding it as a subView to the buttonPad in my view controller file. This worked... but it didn't allow the button to function. I am wondering: A.) Is it appropriate to add buttons or any subview for that matter to the UIView initWithFrame: method or should I be adding these subviews as a subview to my buttonPad in the view Controller file? B.) Since I am creating a custom button/keypad, am i following a valid approach by using a normal UIViewController or should I be using something like a modal view Controller? ( I have little knowledge about these.)
