• Xcode 3.2 + LLVM = no local symbols when debugging

  - by glebd

  I have a project for Mac OS X 10.5 that I'm building on 10.6 using Xcode 3.2. When I use GCC 4.2 for Debug build and hit a breakpoint, Xcode debugger displays local variable information normally. If I choose LLVM GCC 4.2 or Clang LLVM, when I hit breakpoint, local symbols are not available, and GDB says No symbol 'self' in current context if I try to print self or any other local symbol. In all cases Generate debug info option is set. The Debug configuration is set to $(NATIVE_ARCH) and 10.5 SDK, Build active architecture only option is set. When GDB starts, I can see it is being configured as x86_64-apple-darwin. I must be missing something obvious. How do I make GDB show local symbols when using a LLVM compiler?

• wpf manually generate TreeViewItem container

  - by viky

  I am creating a TreeView at runtime. It has several nodes(TreeViewItem), each one having a name. Initially it is collapsed. A separate comboBox displays Names of all TreeViewItem. I have to highlight a TreeViewItem based on the Name selected. I am using a recursive function and gets the TreeViewItem container like this: if (parent.ItemContainerGenerator.Status != GeneratorStatus.ContainersGenerated) continue; TreeViewItem container = parent.ItemContainerGenerator.ContainerFromItem(child).As<TreeViewItem>(); but it is parent.ItemContainerGenerator.Status = GeneratorStatus.NotStarted for all the collapsed items. How can I generate containers for them manually(Without expanding them)?

• ASP.NET - How to add a label to a RadioButtonList ListItem?

  - by EWizard

  I have a RadioButtonList with two ListItems included: <asp:RadioButtonList runat="server" ID="optRollover" OnSelectedIndexChanged="RolloverOptionSelected" AutoPostBack="true"> <asp:ListItem Value="0">100% </asp:ListItem> <asp:ListItem Value="1">Less than 100%</asp:ListItem> </asp:RadioButtonList><br /> On the first ListItem I need to have a label that displays some text from the code behind of the page. Logically it seems to me like I would be able to do something like this: 100% Obviously this does not work because I am getting an error: The 'Text' property of 'asp:ListItem' does not allow child objects. Can anyone think of a way around this constraint?

• Custom realm/starting Tomcat 6.0 from Netbeans 6.8/first HTTP request

  - by Drew

  I'm using NetBeans 6.8 and Tomcat 6.0.xx. I've created a custom realm and updated the NetBeans project build.xml to deploy the realm to Tomcat. When I debug the project, NetBeans starts the Tomcat server and makes an initial HTTP GET request for 'manager/list'. Tomcat graciously hands this request off to my custom realm for authentication. The request gets denied and NetBeans displays the following error in the output window: (note: error is displayed after NetBeans gets access denied) Access to Tomcat server has not been authorized. Set the correct username and password with the "manager" role in the Tomcat customizer in the Server Manager. Do I have something incorrectly configured? How do I prevent NetBeans from issuing this initial request? Thanks, Drew

• xDebug cant find my files. Always looks in localhost

  - by sleeper

  I'm running win7-64bit, NetBeans 7.1.1 and WampServer 2.2 (which has xDebug) I've configured php.ini (xdebug.remote_enable=on, etc.) I create a directory (virtual host called example.dev) and add a test file. (c:/wamp/example/test-xdebug.php) I run debug in NetBeans and the following url displays: http://localhost/example/test-xdebug.php?XDEBUG_SESSION_START=netbeans-xdebug This fails. The browser coughs up the following error message. Not Found. The requested URL /example/test-xdebug.php was not found on this server. I add the correct path to the virtual host, and xDebug Runs Flawlessly: http://example.dev/test-xdebug.php?XDEBUG_SESSION_START=netbeans-xdebug Tried every configuration I could think of. If this is a php.ini config issue, I sure as heck cant find it. If its a NetBeans issue, there is not an option/interface to modify i (that I can find). Please illuminate! thanks sleeper

• IPhone UIView:Is it possible to enable userinteraction only on subviews?

  - by Syg

  Hi guys, I created a viewcontroller that displays a button which is used to slide a view onto the screen. The idea is to place for instance three such viewcontrollers onscreen, resulting in three buttons at the bottom of the screen providing navigation. The viewcontrollers get stacked, so to the top one is now overlaying the other views and therefore the other buttons. Only the top viewcontroller's button is working in this situation, where I would like all three of them to be clickable. I tried disabling userinteraction on the view and enabling it on the buttons only, but it looks like the superview settings overrule the subview settings. Any ideas?

• iPad UISPlitViewController question

  - by saikamesh

  Hi, It is mentioned in the Apple's documentation that if we use UISPlitViewController in our app, then that should be the root view controller. In our iPone app we are showing splash screen for some seconds till the loading of the app finishes. Once it is loaded the home screen needs to be displayed in a SplitViewController. If we use SplitViewController as the root view. How will we show the splash screen which is displayed in a single view where as SplitVieController displays two ViewControllers. Please explain me the how this can be done.

• Visualizing read-only folders

  - by Paul-Jan

  My application displays a folder structure in a tree. The user can browse the contents in these folders, and drag content into the folders. However, some of these folders are readonly (meaning no content can be dragged into them). I'm looking for a clear way of depicting this to the user, so they are aware which folders they can drag to before actually having to try it, i.e. hover state. Something not too alarming or interrupting (no big red crosses overlayed on top of the folder icons, for instance), preferably a recognized standard. Specifically, we are talking about an Outlook add-in showing a SharePoint folder tree here, but I'd much rather get the answer from a generic viewpoint. From the top of my head, I simply don't seem to know any applications that visually mark readonly folders.

• Jquery datePicker

  - by Shane

  I have slight issue with the jquery datepicker in that it displays ABOVE the target box. This is due to the way my page is set up. I found the issue with CSS in my page via firebug, unfortunately it conflicts with about 20 elements. Next I tried hooking into the "beforeShow event" which works but then after the event fires it just recalculates and puts it where ever it wants. beforeShow: function() { $('#ui-datepicker-div').show(); var offset = $('#ui-datepicker-div').offset(); $('#ui-datepicker-div').css({ top: (offset.top + 222) + 'px' }) } Does anyone else have any ideas how how I can reposition this? I just need to move it down by about 200 odd pixels.

• Windows Command Line

  - by Markus O'Reilly

  Does anyone know how to break out of a for loop when it's typed directly into the windows command-line? I know you can use gotos and labels to break out of it when it's in a batch file, but I can't find anything about breaking out of one on the command line. Here's a simple example: C:> for /l %i in (1,0,1) do @ping -n 1 google.com || (echo ^G & msg user "Google is down!" & QUIT) This should infinitely ping google.com. If it ever fails, it beeps (echo ^G), displays a message box to the user "user" that says "Google is down!", and QUITs. I don't know how to do the quit part though. I guess I could do something like taskkill /f /im cmd.exe, but I was looking for something more elegant. Any tips?

The Apple Mac os X CD is something which inspired me. thanks a lot.

• Setting TreeView.DataContext doesn't refresh the tree

  - by dan gibson

  I have a List that I've bound to a TreeView. Setting TreeView.DataContext works - everything displays correctly. I then change the list (add an item to it) and set TreeView.DataContext again (to the same value) but the tree does not refresh with the new items. How do I get the treeview to refresh? This is basically my code: public class xItemCollection : ObservableCollection<xItem> { } public class xItem : INotifyPropertyChanged { xItemCollection _Items; public xItem() { _Items = new xItemCollection(); } public xItemCollection Items {get{return _Items;}} } ... this.RootItem = new xItem(); treeView.DataContext = this; Adding items to the list works until the tree is rendered for the first time. After it is rendered, adding/removing items does not refresh the tree.

• Using PHP script to fill in XML

  - by Yaaqov

  Hi - we are all familiar with "embedding" PHP scripts in HTML pages to do tasks like displaying form results, but how can that be done in a way that displays XML? For example, if I wrote: <? xml version='1.0' ?> <Responses> <?php $body = $_GET['Body']; $fromPh = $_GET['From']; echo echo "<Msg>Your number is: $fromPh, and you typed: $body.</Msg>" ?> </Response> I get a message that states "parse error, unexpected T_STRING on line 1". Any help or tutorials would be appreciated.

• cross domain access in iframe from parent to child

  - by Aparna

  Hi, Could someone please help me with this- I've 2 applications AAA and BBB. The homepage of AAA contains an iFrame which displays the application BBB. When I login to AAA, the same login details should be used to login to BBB(single signon) and on pageload of the homepage of AAA, homepage of BBB should also be loaded in the iFrame. I tried to use javascript to access the form elements of login page of BBB to enter the login data and submit. But the browser gives me a 'Access is denied' error. I did a little reading and came to know that cross- domain communication is not allowed by the browser. Could someone tell me how i can go about achieving this?

• Why does UIImageView "darken"/saturate PNG images, and can I stop it?

  - by Ben

  I have a PNG file in a UIImageView, and next to that I have an EAGLView which displays the continuation of that same image (long story) as a texture, carved from the same original PNG. The point is, that these images, which should match up flawlessly, actually have somewhat differing color saturation. Normally I'd blame my handling of the PNG texture load in GL, but when I hold Preview (with the PNG) up to the iPhone simulator, it's GL that's spot on, and the UIImageView that's wrong! It's taken the image and made it ever-so-slightly more saturated. The image view is opaque with 100% alpha. I verified this on a clean UIImageView with another PNG file when put next to Preview. Anyone know what's up?

• IE8 Debugger: how to load external javascript files?

  - by Chris Barnhill

  I have downloaded and installed IE8. I was playing around with the debugger, but I could not figure out how to load external javascript files. It displays the javascript from the main page, but I need to debug the script in the external files. I have googled various articles that show a screenshot of an IE8 debugger with a drop-down for selecting which script to debug, but my debugger does not feature this. Can anyone help me with this? Thanks.

• XAMPP is caching .html files running as PHP

  - by Lee

  I have XAMPP (latest version) installed on my Mac OS 10.6.3 I've added the following to .htaccess because I want .html to be interpreted as PHP. AddType application/x-httpd-php .php .html The problem is that the default XAMPP config seems to be caching .html files as static... so even though the PHP statements inside are being called (for example, 'echo time()' in index.html displays the dynamic output)... the actual file is being cached. When I make changes to a .html file, I've having to restart Apache for it to load the newest changes. Looking at httpd.conf, it looks like it's loading the following cache mods.. LoadModule file_cache_module modules/mod_file_cache.so LoadModule cache_module modules/mod_cache.so LoadModule disk_cache_module modules/mod_disk_cache.so LoadModule mem_cache_module modules/mod_mem_cache.so Any idea how to implement a system whereby it checks the timestamp of the file, before loading it from cache? Thanks!

• Using jQuery's $.getScript(), can I sense 304 Not Modified Headers?

  - by Tom

  I have an application (a widget) where I use $.getScript() on a 5 minute timer, loading a file every five minutes. I then take the contents of the file I just downloaded, and rebuild my page, so that my widget can update. Most of the time, however, the file is unchanged, and firebug displays a 304 Not Modified header every 5 minutes, as my timer executes $.getScript(). I would like to sense when the file is not modified, so that I don't use up user resources, rebuilding the page for no reason. Is it possible to obtain html headers when using $.getScript()?

• loading data from file into 2d array

  - by Chris

  I am just starting with perl and would like some help with arrays please. I am reading lines from a data file and splitting the line into fields: open (INFILE, $infile); do { my $linedata = <INFILE>; my @data= split ',',$linedata; .... } until eof; I then want to store the individual field values (in @data) in and array so that the array looks like the input data file ie, the first "row" of the array contains the first line of data from INFILE etc. Each line of data from the infile contains 4 values, x,y,z and w and once the data are all in the array, I have to pass the array into another program which reads the x,y,z,w and displays the w value on a screen at the point determined by the x,y,z value. I can not pas the data to the other program on a row-by-row basis as the program expects the data to in a 2d matrtix format. Any help greatly appreciated. Chris

• WPF ComboBox SelectedItem - change to previous value

  - by Taylor

  Hello, I have a ComboBox that has the SelectedItem bound to the ViewModel. <ComboBox SelectedItem="{Binding SelItem, Mode=TwoWay}" ItemsSource="{Binding MyItems}"> When the user selects a new Item in the View ComboBox, I want to display a prompt and verify that they want to make the change. In the SetItem Property setter in the View Model, I display a Dialog to confirm the selection. When they say yes, it works fine. My problem is, when the user clicks on "No" I am not sure who to get the ComboBox to revert back to the previous value. The Property in the ViewModel has the correct older value, however in the View the ComboBox displays the newly Selected Value. I want the user to select an item, confirm they want to go ahead with it, and if they decide not to, I want the ComboBox to revert back to the previous item. How can I accomplish this? Thanks!

• OpenLayers .containsPoint after pan

  - by Adrian

  I've seem to have hit a bug or i have overlooked something. I written some code that enumerates through all the vector features on a OpenLayers Vector layer - to check if the mouse is inside a vector feature - if so then it displays some info based on the feature. I had to write my own methods to do this because the existing OpenLayers Controls( select etc) stop after finding a feature under the mouse, and i the possibility of several features being stacked on top of one another. My problem is that the .containsPoint method seems to be using coords from before a 'pan'. After zooming in or out the geometry seems to be in the right place and .containsPoint is works correctly when I wave the mouse over the map. Do I need to do something after the map has been panned to update something( feature's geometry)

• BigDecimal precision not persisted with javax.persistence annotations

  - by dkaczynski

  I am using the javax.persistence API and Hibernate to create annotations and persist entities and their attributes in an Oracle 11g Express database. I have the following attribute in an entity: @Column(precision = 12, scale = 9) private BigDecimal weightedScore; The goal is to persist a decimal value with a maximum of 12 digits and a maximum of 9 of those digits to the right of the decimal place. After calculating the weightedScore, the result is 0.1234, but once I commit the entity with the Oracle database, the value displays as 0.12. I can see this by either by using an EntityManager object to query the entry or by viewing it directly in the Oracle Application Express (Apex) interface in a web browser. How should I annotate my BigDecimal attribute so that the precision is persisted correctly? Note: We use an in-memory HSQL database to run our unit tests, and it does not experience the issue with the lack of precision, with or without the @Column annotation.

But I cannot resolve the Company - Passenger (Show all Passengers of a Company). My controller for Company: function index(){ //grab all companies and pass it to the view: $companies = $this->Company->find('all'); $this->set('companies', $companies); } This displays all companies with all their respective cars. However the array does not contain an entry for passenger. What do I have to do to completely resovle the Company - Car - Passenger relation?
