• Add UIView Above All Other Views, Including StatusBar

  - by Mike Stead

  I'm wanting to create a view (UIControl) which blocks all input and shows a UIActivityIndicatorView while authenticating a user. The UIActionSheet and UIAlertView both manage to add a black semi-transparent view over the top of all other views to block input and I'd like to do similar. I've tried adding my view to the top UIWindow in the [[UIApplication sharedApplication] windows] array, and while this does place it above the UIKeyboard if it's visible, it doesn't place it over the StatusBar (which makes sense). My next attempt was to extend UIAlertView, remove all of its subviews and set its layer.contents = nil, then add the ActivityIndicator as a subview. This works well, but I can't seem to kill the default bouncy transition of the UIAlertView when you call it to "show". Does anyone have any pointers towards the best way tackle this problem that gives me full control? Oh and I know blocking input is not great but I do ensure it's for a short period of time and it has the benefit of making it clear to the user that their action, which must complete for them to progress, is processing.

• Zend framework helper intellisense

  - by Nicky De Maeyer

  Not so much a programming problem, but more a productivity problem. We've got quite a few custom view and action helpers in our project. Working with around 7 programmers. Now when someone, creates a helper or if one would want to use a helper, it all goes through the brokers. This means we do not get intellisense for those helpers, which can be real time consuming, having to go look in the docs or the code files. This is ofcourse true for both build in and custom helpers. Does any1 share this pain? Does any1 have a solution for this?

• PLCameraController is not adding in viewcontroller

  - by sujyanarayan

  Hi, I've declared PLCameraContoller instance in my AppDelegate class as:- self.cameraController = [PLCameraController performSelector:@selector(sharedInstance)];[cameraController setDelegate:self]; And I'm accessing it in one of my viewcontroller class as:- del = [[UIApplication sharedApplication] delegate]; UIView previewView = [del.cameraController performSelector:@selector(previewView)]; previewView.frame = CGRectMake(0,0, 320, 480); self.view = previewView; [del.cameraController performSelector:@selector(startPreview)]; [del.cameraController performSelector:@selector(setCameraMode:) withObject:(NSNumber)1]; Where "del" is an instance of my AppDelegate class. But i can see only black background in my viewcontroller view in iphone device. Also if i remove "self" from the appdelegate.m code of cameracontroller it also showing blank. How can i get camera in my view controller? I'm pretty much struggling with it. Thanks in Adv.

• Ajax Fancy Capture in CakPHP

  - by Constantin.FF

  I have found a nice ajax capture which i would like to use in a CakePHP framework website. The plugin can be found here: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin What I have tried: in the controller: public function index($slug = null, $capture = false) { if($capture AND $capture =="get_capture"){ $rand = rand(0,4); $_SESSION['captcha'] = $rand; echo $rand; die; } if (!empty($this->data) && $_POST['captcha'] == $_SESSION['captcha']) { .... save the post } } in the view: $selectURL = " $(function() { $('.ajax-fc-container').captcha({ borderColor: 'silver', captchaDir: 'http://localhost/img/capture', url: 'http://localhost/contacts/index/contacts/get_capture', formId: 'MessageIndexForm', }); });"; $this->Html->scriptBlock($selectURL, array('inline' => false)); also I have tried with url: 'http://localhost/js/capture.php' which is the original file coming with the plugin but still not working.

• a4j:commandButton causes full page reload on IE7

  - by Greg Charles

  Our process allows users to activate their account, and then configure e-mail preferences. We're using the tag: <a4j:commandButton id="activate" action="#{controller.agreeAction}" image="/img/ok.png" styleClass="activate-button" reRender="mainContent, sideBar" oncomplete="showEmailDialog();" /> This works fine on Firefox, but on IE, the showEmaiDialog() fires off to display the new dialog, and then the full page reloads, which instantly hides it again. I put in numerous alert() calls to make sure of what was happening. I see the e-mail dialog until I clear the final alert box in in the showEmailDialog() script, and then I see the alerts that I put into jQuery(document).ready(). Why does IE do a full page reload instead of just refreshing the requested sections?

• Setting Position of NSWindow before Display

  - by Armin Ronacher

  Right now I'm setting the position of a window that is about to open like this: -(void) setActiveNodeDialog:(ISKNodeDialogController *)dialog { if (activeNodeDialog) [[activeNodeDialog window] close]; activeNodeDialog = dialog; if (activeNodeDialog) { [activeNodeDialog setMainWindowController:self]; NSRect windowRect = [[self window] frame]; NSRect dialogRect = [[activeNodeDialog window] frame]; NSPoint pos; pos.x = windowRect.origin.x + windowRect.size.width - dialogRect.size.width - 10; pos.y = windowRect.origin.y + 32; [[activeNodeDialog window] setFrameOrigin:pos]; [[activeNodeDialog window] makeKeyAndOrderFront:nil]; } } The problem with that is, that the window will "jump" when shown. And that even though I set the position before showing the window with "makeKeyAndOrderFront". The window is a NSPanel *. Anyone any ideas how to fix the jumping? Setting the position in awakeFromNib is not an option because the main controller is set later.

• algorithm advice for finding maximum items within a time period

  - by darren

  Hi everyone. I have a database schema that is similar to the following: | User | Event | Date |--------|---------------|------ | 111 | Walked dog | 2009-10-1 | 222 | Walked dog | 2009-10-2 | 333 | Fed Fish | 2009-10-5 | 222 | Did Laundry | 2009-10-6 | 111 | Fed Fish | 2009-10-7 | 111 | Walked dog | 2009-10-18 | 222 | Walked dog | 2009-10-19 | 111 | Fed Fish | 2009-10-21 I would like to produce a query that returns the maximum number of times a user performs some action within a time period. For example, given a time period of 5 days, what is the maximum number of times user 111 walked the dog? The most obvious solution would be to start at some zero point and move forward each day, summing up 5 day periods along the way, then taking the maximum total out of all the 5 day windows. the approach seems incredibly costly however. I would appreciate any suggestions you may have.

• How to index a string like "aaa.bbb.ddd-fff" in Lucene?

  - by user46703

  Hi, I have to index a lot documents that contain reference numbers like "aaa.bbb.ddd-fff". The structure can change but it's always some arbitrary numbers or characters combined with "/","-","_" or some other delimiter. The users want to be able to search for any of the substrings like "aaa" or "ddd" and also for combinations like "aaa.bbb" or "ddd-fff". The best I have been able to come up with is to create my own token filter modeled after the synonym filter in "Lucene in action" which spits out multiple terms for each input. In my case I return "aaa.bbb", "bbb.ddd","bbb.ddd-fff" and all other combinations of the substrings. This works pretty well but when I index large documents (100MB) that contain lots of such strings I tend to get out of memory exceptions because my filter returns multiple terms for each input string. Is there a better way to index these strings?

• Workaround for richfaces combobox hotkey bug

  - by John

  Hi, Does anyone know a workaround for the bug https://jira.jboss.org/jira/browse/RF-8076 ? Just to clarify things, we have a form with multiple inputs, one of them being a combobox with auto complete features. We've setup a hotkey via <rich:hotKey key="return" ... /> It works great everywhere except in the combobox, and I would really like to get it working on the combobox as well. The behaviour I want when the ENTER key is pressed inside the combobox is: If the combobox context was modified by auto complete then do nothing Else action the event on ENTER key pressed We're running on seam/richfaces. I'm open to any workaround, but simplicity is much sought for. Thanks!

• JQuery display problems?

  - by DuH

  I'm new to JQuery and was wondering how can I have Changes saved! displayed only once even if the user presses the submit button multiple times for example if a user decides to change there info three different times the text, Changes saved!Changes saved!Changes saved! is displayed i only want Changes saved! displayed once. How can I fix this problem? What part of my code needs to be fixed? Here is the JQuery code. $(function() { $('#changes-saved').hide(); $('.save-button').click(function() { $.post($('#contact-form').attr('action'), $('#contact-form').serialize(), function(html) { $('div.contact-info-form').html(html); $('#changes-saved').append('Changes saved!').show(); }); $('a').click(function () { $('#changes-saved').empty(); $('#changes-saved').hide(); }); return false; // prevent normal submit }); });

• How small is *too small* for an opensource project?

  - by Adam Lewis

  I have a fair number of smaller projects / libraries that I have been using over the past 2 years. I am thinking about moving them to Google Code to make it easier to share with co-workers and easier to import them into new projects on my own environments. The are things like a simple FSMs, CAN (Controller Area Network) drivers, and GPIB drivers. Most of them are small (less than 500 lines), so it makes me wonder are these types of things too small for a stand alone open-source project? Note that I would like to make it opensource because it does not give me, or my company, any real advantage.

• Why does addSubview load the view asynchronously

  - by moshe

  I have a UIView that I want to load when the user clicks a button. There happens to be some data processing that happens as well after I call addSubview that involves parsing an XML file retrieved from the web. The problem is the view doesn't show up until after the data processing even if addSuview is called first. I think I'm missing something here, can anyone help? Code: I have a "Loading..." view I'm adding as a custom modal (meaning I'm not using the modalViewController). This action is linked to a button in the navigationController. - (IBAction)parseXml:(id)sender { LoadingModalViewController *loadingModal = [[LoadingModalViewController alloc] initWithNibName:@"LoadingModalViewController" bundle:nil]; [navigationController.view addSubview:loadingModal.view]; [xmlParser parse]; }

• Passing a variable to jsp when reloading an iframe using javascript

  - by Vee

  In my javascript code I load a jsp page in an iframe and pass some variables like this: htmlData[i++]="<iframe id=\"mapframe\" frameborder=\"0\" style=\"width:330px;height:300px\" src=\"" + "mapURL.jsp" +"&lat=" + AjxStringUtil.urlComponentEncode("33.65") +"&lng=" + AjxStringUtil.urlComponentEncode("-84.42") +"&accord=" + AjxStringUtil.urlComponentEncode(accord) +"\"></iframe>"; Then I have to reload that jsp page after an action, and I do this: accord = ui.newHeader.text(); document.getElementById('mapframe').contentWindow.location.reload(); The reload works except that the "accord" variable is not getting updated. When I call it from the jsp, it still has its original value. How do I pass the new value when reloading the iframe/jsp? It shouldn't make any difference, but I am working with jquery and this is for a Yahoo zimlet. Thanks.

• Symfony Rewrite rules on Zeus webserver

  - by Ben

  I would like to run a symfony project on a zeus webserver, however i cannot get the rewrite rules to work. Has anyone done this successfully The symfony .htaccess is as follows: Options +FollowSymLinks +ExecCGI <IfModule mod_rewrite.c> RewriteEngine On # uncomment the following line, if you are having trouble # getting no_script_name to work #RewriteBase / # we skip all files with .something #RewriteCond %{REQUEST_URI} \..+$ #RewriteCond %{REQUEST_URI} !\.html$ #RewriteRule .* - [L] # we check if the .html version is here (caching) RewriteRule ^$ index.html [QSA] RewriteRule ^([^.]+)$ $1.html [QSA] RewriteCond %{REQUEST_FILENAME} !-f # no, so we redirect to our front web controller RewriteRule ^(.*)$ index.php [QSA,L] </IfModule> From what I can tell the following should work on zeus: match URL into $ with (^(.*)$) if matched then set URL = index.php But it doesn't... I can only load the home page from / all other pages just 404. Thanks..

• Partial form with nested routes

  - by jerhinesmith

  I have two models -- User and Entry -- that are related through a has_many relationship (a User has many Entries). I'm using RESTful routing, and have the following in my routes.rb file: map.resource :user, :controller => "users" do |user| user.resources :entries end This seems to work, but in my partial _form file, when I do this: form_for [@current_user, @entry] do |f| # Form stuff end It generates a URL like this: /user/entries.%23%3Cuser:0xb6a6aea8%3E instead of /user/entries Am I missing something? I should note that the correct classes are applied to the form when doing creation vs. editing, so it does seem to be correctly interpreting what I'm trying to do -- it's just that I can't submit the form to an invalid url.

• Weird behavior of an ASP.NET MVC application - track of errors

  - by Alex

  Before migrating from ASP.NET WebForms I had a very good way to monitor all my application errors in the Events Log (Administrative Tools). But now after moving to asp.net MVC, all I get is the same mistake occurring every minute (something about Site Master). I know it's not right, because there are other mistakes, but they are not displayed. I purposefully put in division by zero operation, and it didn't track it. I had to implement the OnException method of a controller, and send e-mails with error details which is very inconvenient. How can I solve this problem?

• How to force HtmlUnit to save page?

  - by booroondook

  Hello. I'm using HtmlUnit to click on a HtmlElement that triggers Javascript action: currentPage = ((HtmlElement) currentPage.getByXPath("//*[contains(@onclick, 'check();')]").get(0)).click(); The element is: <a href="#" onclick="check(); return false;"> The page returned is quite similar to the page, containing that element: same URL, mostly same HTML, but there are some minor differences in the HTML and HtmlUnit doesn't save the new page. I'm using HttpAnalyzer to sniff the traffic and I see that the Webclient correctly handles JS and send the right request. The response is also correct, but when I dump the contents of the currentPage to a file, I see that the actual page didn't change. How can I fix it?

• UITableView setting standalone delegate object?

  - by fuzzygoat

  Hi have setup a sample application using a UITableView. Initially I did this by conforming my controller to and , added a tableView in IB and connected "datasource" & "delegate" to Files Owner. It all works so thats good. What I have been trying out is creating my own class for the delegate. I created a new class and added and , but quickly found I could not connect the tableViewdataSource / delegate. To solve this I added an "Object" (NSObject) in IB and set it to my new class. I then connected the dataSource and delegate outlets to this object. It sort of works, the app runs and displays the tableView, but when I try and scroll the table the app crashes. Can I ask if I am going about this the right way? gary

• 8051 microcontroller kit recommendation?

  - by LucidDefender

  I'm a first year Computer Science student looking to get started with development for micro-controllers. I'd like to use the 8051, as it's common as dirt, and is used frequently in the real world. During my junior or senior year, I'll be taking a PIC micro-controller based embedded design class, so I'd rather not do PIC now; otherwise, I'll be fairly bored during that course. Most commercial kits I see are for the AVR or PIC series of microprocessors. I'm just looking for something with decent development tools, documentation, and enough add-ons to keep my novice self occupied for the summer. Any recommendations for an 8051 family kit? Thanks!

• What's a good way to create an Event Calendar

  - by iFloh

  Hi, I want to create an Event Calendar for my iPhone App. In a first instance the Event Calendar is supposed to list the Events and have a Details View with additional info. It is also supposed to contain an action to trasfer a specific event to the iPhone Calendar. First thoughts go towards using a UITableView where I make the event dates as sections. Since the Calendar is supposed to span many month I am unsure whether this really is the best way to go about it. Any suggestions? Do you probably know some sample code that I might use ? thanks in advance

• Ruby on Rails - f.error_messages not showing up

  Hi, I've read many posts about this issue but I never got this to work. My model looks like this: class Announcement < ActiveRecord::Base validates_presence_of :title, :description end My controller's create method(only its relevant part) looks like this: def create respond_to do |format| if @announcement.save flash[:notice] = 'Announcement was successfully created.' format.html { redirect_to(@announcement) } format.xml { render :xml => @announcement, :status => :created, :location => @announcement } else @announcement = Announcement.new @provinces = Province.all @types = AnnouncementType.all @categories = Tag.find_by_sql 'select * from tags where parent_id=0 order by name asc' @subcategories= '' format.html { render :action => "new" } #new_announcement_path format.xml { render :xml => @announcement.errors, :status => :unprocessable_entity } end end end My form looks like this: <% form_for(@announcement) do |f| %> <%= error_messages_for 'announcement' %> <!--I've also treid f.error_messages--> ...

• Mockito upgrade causes null pointer problems

  - by Ann Addicks

  We upgraded from mockito-all-1.8.5.jar to mockito-all-1.9.0.jar and now see null pointers when using annotations for the classes being mocked. Here is an example: @Mock private static IAccountManager accountManager; @Mock private static IBusinessUnitManager businessUnitManager; private static Gson parser; @InjectMocks private static DownloadController downloadController; @BeforeClass public static void setUpBeforeClass() throws Exception { parser = new Gson(); downloadController = new DownloadController(accountManager, businessUnitManager, parser); } @Before public void setUp() throws Exception { MockitoAnnotations.initMocks(this); Mockito.reset(accountManager, businessUnitManager); } As soon as accountManager is referenced in the download controller, it throws a npe. This worked in 1.8.5.

• 2008 Datacenter Word Automation issue

  - by Brad

  We have an application that uses word automation. It works fine under Windows XP, but does not work on our Windows Server 2008 64-bit virtual machine running on VMware ESX unless it is running as the domain administrator. Under any other account (including a local admin), Word starts, uses a lot of CPU for 40 seconds when opening a document, and then just hangs. Our application does not access anything not on the local machine, and this machine is not being used for anything else (not a domain controller, etc). I know others have posted similar issues, with the solution of creating a Desktop folder somewhere under the windows directory. We did this, and it did not solve the problem (Word did not get as far as it did before we did this though). Please don't turn this into a thread about why I am trying to do this, whether I should do this, or whether I need to. For argument sake, I don't need to do this, but understanding what privilege a local admin does not have that is needed to do this is a legitimate concern.

• Attaching javascript events to form widgets

  - by user334017

  I have a form with a drop down menu and I want to do a javascript action whenever the user changes the selection. I imagine it is possible find the input later, using javascript, and attach an event to to it; but it seems like it would be easier if there was some sort of attribute or option that could be defined in form-configure(): e.g. $this->widgetSchema['menu'] = new sfWidgetFormChoice(array( ... 'onclick' => javascript function )); obviously this doesn't work, and it probably wouldn't be an onclick method either, but my question is how do you attach a javascript event to a input/widget?
