  • How to add and relate a node within the parent nodes add form in Drupal.

    - by Espen Christensen
    Hi, I want to accomplish the following scenario in Drupal: You have 2 content-types. Lets say, an application-form for a lisence, and a content-type for persons. Then when you go to add a lisence in the "node/add" submission form in Drupal, i would like to add a relative number of persons that would be related to this lisence, and only this lisence. Say you would like to apply for a lisence, and relate 4 persons to this lisence, then insted of creating the lisence and then create the 4 persons and relate them to the lisence, i would like to do this "inline". So when i add a lisence, there would be a way to add 1 or more persons that would relate to the lisence node. Is this possible, and if so how? I have been looking at the node reference module, and that manages to reference a node to another, but not to add them inline with the other. With the web-development framework Django, there is a way to this with something called "inline-editing", where you get the content-type fields inside another content-type creation form. There you bind them togheter with a ForeignKey. Anybody know of something simular in Drupal, if not, is it another way to achive something simular, that would be as user-friendly?

  • How do I reference an unsigned assembly from a VSTO Word Doc project?

    - by Gishu
    I created a new project in VS2008. Project type Visual C# > Office > 2007 > Word 2007 Document Added some code.. got Word to do a few jumps through some custom hoops.. all fine. Now I need to reference another assembly (CopyLocal as false) which is not signed. So I add the project reference. Now the project will not build complaining error MSB3188: Assembly 'X.dll' must be strong signed in order to be marked as a prerequisite. The error code page is concise (now accustomed to this) Been googling and reading posts ever since.. No Luck. How do I get around this ? Or is the hidden commandment that all references (for VSTO?) must be strong named / signed. I cannot sign 'X.dll' and be done with it because it is a binary that I don't control also it depends on another bunch of unsigned dlls.. can't set off a chain sign reaction. Update: Solved the build issue by turning CopyLocal=True. But this meant dumping the referenced X.DLL and all its dependencies into the bin\debug folder... Ughh! Tried creating a subfolder called bin\debug\refExecs and referencing X.dll CopyLocal=false from there. The error message was back.

  • how to access a type defined in one .ml file in another .ml file

    - by user339261
    Hi, I m very new to ocaml and i m facing the problem below, In a.ml a record type t is defined and is also defined transparently in a.mli, i.e. in d interface so that the type definition is available to all other files. a.ml also has a function, func, which returns a list of t. Now in another file, b.ml i m calling func, now obviously ocaml compiler wud nt be able to infer d type of objects stored in d list, for compiler its just a list. so in b.ml, i hav something like dis, let tlist = A.func in let vart = List.hd tlist in printf "%s\n" vart.name (name is a field in record t) Now here i get a compiler error sayin "Unbound record field label name" which makes sense as compiler can't infer d type of vart. my first question: how do I explicitly provide d type of vart as t here? i tried doing "let vart:A.t = " but got the same error. I also tried creating another function to fetch the first element of d list and mentioning return type as A.t, but then i got the "Unbound value A.t". I did this: let firstt = function [] - 0 | x :: _ - A.t x ;; The problem is compiler is unable to recognize A.t (a type) in b.ml but is able to recognize function A.func. If I remove A.t from the b.ml, i don'get any compiler errors. Please help, its urgent work. Thanks in advance! ~Tarun

  • AuthorizationExecuteWithPrivileges and osascript failing

    - by cygnl7
    I'm attempting to execute an uninstaller (written in AppleScript) through AuthorizationExecuteWithPrivileges. I'm setting up my rights after creating an empty auth ref like so: char *tool = "/usr/bin/osascript"; AuthorizationItem items = {kAuthorizationRightExecute, strlen(tool), tool, 0}; AuthorizationRights rights = {sizeof(items)/sizeof(AuthorizationItem), &items}; AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagExtendRights | kAuthorizationFlagPreAuthorize | kAuthorizationFlagInteractionAllowed; status = AuthorizationCopyRights(authorizationRef, &rights, NULL, flags, NULL); Later I call: status = AuthorizationExecuteWithPrivileges(authorizationRef, tool, kAuthorizationFlagDefaults, (char *const *)args, NULL); On Snow Leopard this works fine, but on Leopard I get the following in syslog.log: Apr 19 15:30:09 hostname /usr/bin/osascript[39226]: OpenScripting.framework - 'gdut' event blocked in process with mixed credentials (issetugid=0 uid=501 euid=0 gid=20 egid=20) Apr 19 15:30:12: --- last message repeated 1 time --- ...

  • Subscription website architecture questions + SQL Server & .NET

    - by chopps
    Hey Guys, I have a few questions about the architecture of a subscription service I am about to embark on and I am looking for some feedback on how best to set it up. I won’t have a large amount of customers as Basecamp, maybe a few hundred and was wondering what would be a solid architecture for setting up the customer sites. I’m running SQL Server and .NET on a dedicated machine. Should create a new database for each customer as to have control and isolation of data or keep them all in one database? I am also thinking of creating a sub-domain for each customer as well so modifications can be made to each site as needed. The customer URLs would look like this: https://customer1.foobar.com https://customer2.foobar.com I am going to have the ability to ‘plug-in’ reports that will be uploaded to the site so each customer can customize as needed. Off the top of my head this necessitates having each sub domain on its own code-base for the uploading of these reports. So on the main site the customer would sign up for their new subscription and I would programmatically create a new directory for the customer from the main code base and then create a sub domain pointing to the new directory for the customer and then finally their database. Does this sound about right? Am I on the right track? How do other such sites accomplish the same thing? Thanks for letting me bend your ear for a bit on this.

  • Mimic remote API or extend existing django model

    - by drozzy
    I am in a process of designing a client for a REST-ful web-service. What is the best way to go about representing the remote resource locally in my django application? For example if the API exposes resources such as: List of Cars Car Detail Car Search Dealership summary So far I have thought of two different approaches to take: Try to wrangle the django's models.Model to mimic the native feel of it. So I could try to get some class called Car to have methods like Car.objects.all() and such. This kind of breaks down on Car Search resources. Implement a Data Access Layer class, with custom methods like: Car.get_all() Car.get(id) CarSearch.search("blah") So I will be creating some custom looking classes. Has anyone encoutered a similar problem? Perhaps working with some external API's (i.e. twitter?) Any advice is welcome. PS: Please let me know if some part of question is confusing, as I had trouble putting it in precise terms.

  • DNS-Based Environment Determination

    - by zvolkov
    Found the following here. The questions is: where can I find more details on how exactly implement this on Windows? Any guide or how-to anybody? Or maybe you can provide your invaluable suggestions? Specifically, how do I make so that "all QA servers would first resolve entries in qa.example.com first and then if that lookup failed they would try example.com" (I'm a dev, not a DNS specialist, but our IT Support has refused to help on this:() Use DNS Based Environment Determination for your servers. Do this by initially splitting your top level domain into a number of sub domains depending on their function, and then creating DNS Service Names in each of the sub domains pointing to the relevant server for that service. Based on the list above we would then have: * clientdb.prod.example.com for Production * clientdb.perf.example.com for Performance Testing * clientdb.qa.example.com for QA * clientdb.dev.example.com for Development Servers then resolve entries in their relevant sub domain by function. That is, all QA servers would first resolve entries in qa.example.com first and then if that lookup failed they would try example.com. This allows you to have a single configuration entry for your client database hostname (clientdb) that would resolve correctly in all environments. This technique has the added advantage of still having global services defined in a common top level domain. Here's one related (but not equivalent) SO question: http://stackoverflow.com/questions/774490/dns-resolving-based-on-client-ip This seems to be related to Providing "split horizon" DNS service. Reading that, I see that I will probably need separate DNS Server for each environment. Is this true or does Windows support some form of "tagging" the records to be visible depending on the requestor's IP? Also, cross-posted on ServerFault

  • Allowing user to edit only the page content and some custom fields in wordpress

    - by GaVrA
    This is the site: http://www.backpackers.rs Using "User Role Editor" i have user group that can only read and edit published pages so i can have as many users as i want in that user group and they all will have only one published page on their own so they can edit only that page. Now, this is how a user in that user group currently is seeing "edit page" page: http://i39.tinypic.com/rwuesh.png What i need is to disable all those things that have a red border around it + something with custom fields. So i need to disable these things for user in that user group: ability to change status of the page entire "Attributes" block is something that he/she must not see or be able to change ability to change something in "Discussion" block he/she shouldnt see "Page revisions" block i need a way to give those users ability to use only some custom fields. Currently we have 6 custom fields, and i want to give these users ability to only use 4 of those custom fields. i need to disable these users from creating new custom fields. I dont need complete answers for these things, something to get me started is really what i need. I have been reading codex a lot, but still didnt find something to help me with this, so basically any answer is more then appreciated!

  • Increase performance on iphone at pdf rendering

    Hi! I have a UITableView, and in every cell there's displayed a UIImage created from a pdf. But now the performance is very bad. Here's my code I use to generate the UIImage from the PDF. Creating CGPDFDocumentRef and UIImageView (in cellForRowAtIndexPath method): ... CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), (CFStringRef)formula.icon, NULL, NULL); CGPDFDocumentRef documentRef = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CFRelease(pdfURL); UIImageView *imageView = [[UIImageView alloc] initWithImage:[self imageFromPDFWithDocumentRef:documentRef]]; ... Generate UIImage: - (UIImage *)imageFromPDFWithDocumentRef:(CGPDFDocumentRef)documentRef { CGPDFPageRef pageRef = CGPDFDocumentGetPage(documentRef, 1); CGRect pageRect = CGPDFPageGetBoxRect(pageRef, kCGPDFCropBox); UIGraphicsBeginImageContext(pageRect.size); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, CGRectGetMinX(pageRect),CGRectGetMaxY(pageRect)); CGContextScaleCTM(context, 1, -1); CGContextTranslateCTM(context, -(pageRect.origin.x), -(pageRect.origin.y)); CGContextDrawPDFPage(context, pageRef); UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return finalImage; } What can I do to increas the speed and keep the memory low?

  • C#JSON serialization

    - by Bridget the Midget
    I'm trying out the HighStock library for creating stock charts. To fill the chart with data, their example specifies this source. The first parameter is unixtime in milliseconds and the second parameter is the stock closing price. I don't know if this is valid json, but I would argue that the following would be a more appropriate way of writing json. [{"Closing":63.15000,"Date":1262559600000},{"Closing":64.75000,"Date":1262646000000}, ... I guess that I have no other option than to adapt to HighStocks syntax. I could solve this by looping and add correct syntax to a string, but that seems rudimentary. Would it be more wise to serialize C# objects to create my json, and if that's the case - how can I reach the syntax specified in the example? Lets just say this is my c# object: public class Quote { public double Date { get; set; } public decimal Closing { get; set; } } Am I making it unnecessary complex? Should I just format a json string?

  • how to keep a nativewindow on top

    - by Freddy Rios
    I need to keep a NativeWindow I am creating on top of the main window of the application. Currently I am using alwaysInFront = true, which is not limited to the windows in the application. I can successfully synchronize the minimize/restore/move/resize actions, so the top window behaves appropriately in those cases. Even though using this option has the drawback that if I alt-tab to other application the window goes on top of the other application. Because of the above I am trying to get it to work without using the alwaysInFront. I have tried using orderInFrontOf and orderToFront, which gets it in place but when I click an area in the main window the top one becomes hidden i.e. air makes it the top one. I have tried capturing activate/deactivate events but it only happens on the first click, so on the second click the top window becomes hidden again. I also tried making the top window active when the main one becomes active, but that causes the main one to loose focus and I can't click on anything. Ps. I am doing this to improve the behavior of a HTMLOverlay I am using - see http://stackoverflow.com/questions/1044927/flex-air-htmlloader-blank-pop-up-window-when-flash-content-is-loaded/1077738#1077738

  • How can I track down "Template process failed: undef error" in Perl's Template Toolkit?

    - by swisstony
    I've moved a Perl CGI app from one web host to another. Everything's running fine except for Template Tookit which is giving the following error: "Template process failed: undef error - This shouldn't happen at /usr/lib/perl5/5.8.8/CGI/Carp.pm line 314." The templates are working fine on the other web host. I've set the DEBUG_ALL flag when creating the template object, but it doesn't provide any additional info about errors just loads of debug output. I can't post the template source as there's lots of client specific stuff in it. I've written a simple test template and that works okay. Just wondering if anyone had seen this error before or has any ideas on the quickest way to find a fix for it. EDIT: Here's a snippet of the code that loads and processes the template. my $vars = {}; $vars->{page_url} = $page_url; $vars->{info} = $info; $vars->{is_valid} = 0; $vars->{invalid_input} = 0; $vars->{is_warnings} = 0; $vars->{is_invalid_price} = 0; $vars->{output_from_proc} = $proc_output; ... my $file = 'clientTemplate.html'; #create ref to hash use Template::Constants qw( :debug ); my $template = Template->new( { DEBUG => DEBUG_SERVICE | DEBUG_CONTEXT | DEBUG_PROVIDER | DEBUG_PLUGINS | DEBUG_FILTERS | DEBUG_PARSER | DEBUG_DIRS, EVAL_PERL => 1, INCLUDE_PATH => [ '/home/perlstuff/templates', ], } ); $template->process( $file, $vars ) || die "Template process failed: ", $template->error(), "\n";

  • In VB.net websites, VS2008 ALWAYS uses space indentation for new files

    - by Jez
    So, I've changed my settings in Tools | Options | Text Editor, for All Languages, Basic, and C#, to having Block indenting, and 'Keep tabs'. I've also tried this with Smart indenting too. Now, although once I start editing a file, its auto indentation is done with tabs, when I create a new web form in my ASP.net website, VS2008 insists on creating the initial code with space indentation. So for example, I'll get an aspx.vb file for my new page like so: Partial Class Admin_Index Inherits System.Web.UI.Page End Class Note that the 'Inherits' line is SPACE-indented, even though I have the text editor settings set to keep tabs. Is there any way I can make the default created files indented with tabs, not spaces? Or is VS just too stubborn? :-) By the way, please don't just respond and say this is petty as I can quickly change that one line of indentation to using a tab. I know this, but I have a software team that find it irritating as we have an SVN hook that prevents checkins if there's any space-indentation. It would be very useful if any newly-created files have tab indentation from the start, rather than us having to change it every time.

  • Neural Network settings for fast training

    - by danpalmer
    I am creating a tool for predicting the time and cost of software projects based on past data. The tool uses a neural network to do this and so far, the results are promising, but I think I can do a lot more optimisation just by changing the properties of the network. There don't seem to be any rules or even many best-practices when it comes to these settings so if anyone with experience could help me I would greatly appreciate it. The input data is made up of a series of integers that could go up as high as the user wants to go, but most will be under 100,000 I would have thought. Some will be as low as 1. They are details like number of people on a project and the cost of a project, as well as details about database entities and use cases. There are 10 inputs in total and 2 outputs (the time and cost). I am using Resilient Propagation to train the network. Currently it has: 10 input nodes, 1 hidden layer with 5 nodes and 2 output nodes. I am training to get under a 5% error rate. The algorithm must run on a webserver so I have put in a measure to stop training when it looks like it isn't going anywhere. This is set to 10,000 training iterations. Currently, when I try to train it with some data that is a bit varied, but well within the limits of what we expect users to put into it, it takes a long time to train, hitting the 10,000 iteration limit over and over again. This is the first time I have used a neural network and I don't really know what to expect. If you could give me some hints on what sort of settings I should be using for the network and for the iteration limit I would greatly appreciate it. Thank you!

  • How to set different width for INPUT and DIV elements with Scriptaculous Ajax.Autocompleter?

    - by Grzegorz Gierlik
    Hello, I am working on autocompleter box based on Scriptaculous Ajax.Autocompleter. Here how my HTML/JS code looks like: <input type="text" maxlength="255" class="input iSearchInput" name="isearch_value" id="isearch" value="<wl@txt>Search</wl@txt>" onfocus="this.select()"> <br> <div id='isearch_choices' class='iSearchChoices'></div> <script> function iSearchGetSelectedId(text, li) { console.log([text, li.innerHTML].join("\n")); document.location.href = li.getAttribute("url"); } document.observe('dom:loaded', function() { new Ajax.Autocompleter("isearch", "isearch_choices", "/url", { paramName: "phrase", minChars: 1, afterUpdateElement : iSearchGetSelectedId }); $("isearch_choices").setStyle({width: "320px"}); }); </script> and CSS classes: input.iSearchInput { width: 155px; height: 26px; margin-top: 7px; line-height: 20px; } div.iSearchChoices { position:absolute; background-color:white; border:1px solid #888; margin:0; padding:0; width: 320px; } It works in general, but I need to have list of choices wider then input box. My first try was to set various width with CSS classes (like above), but it didn't work -- list of choices became as wide as input box. According to Firebug width defined by my CSS class was overwritten by width set by element.style CSS class, which seems to be defined by Ajax.Autocompleter. My second try was to set width for list of choices after creating Ajax.Autocompleter $("isearch_choices").setStyle({width: "320px"}); but it didn't work too :(. No more ideas :(. How to set different width for list of choices for Scriptaculous Ajax.Autocompleter?

  • Silverlight Data Access - how to keep the gruntwork on the server

    - by akaphenom
    What technologies are used / recommended for HTTP Rpc Calls from Silverlight. My Server Side stack is JBoss (servlets / json_rpc [jabsorb]), and we have a ton of business logic (object creation, validation, persistence, server side events) in place that I still want to take advantage of. This is our first attempt at bringing an applet style ria to our product, and ideally we keep both HTML and Silverlight versions. For better or worse the powers that be have pushed us down the silverlight path, and while flex / java fx / silverlight is an interesting debate, that question is removed from the equation. We just have to find a way to get silverlight to behave with our classes. Should I be defining .NET Class representation of our JSON objects and the methodology to serialize / deserialize access to those objects? IE "blah.com/dispenseRpc?servlet=xxxx&p1=blah&p2=blahblah creating functions that invoke the web request and convert the incomming response string to objects? Another way would be to reverse engineer the .NET wcf(or whatever) communications and implement the handler on the Java side that invokes the correct server side code and returns what .NET expects back. But that sounds much trickier. T

  • Perl, share package variable without Export

    - by Mike
    I'm creating a group of Perl scripts, and I would like to have one package store a group of constants. I don't want to export them using Exporter because there will be quite a few and I don't want to pollute the namespace. Since there will be so many, I don't want to require the user to be forced to manually specify which they will be using. I think the best way to just use the packagename::var syntax, however it doesn't seem to be working as I expect it to. I illustrate this problem in the below code This is settings.pm, the module that will hold the global settings #!/usr/bin/perl #settings.pm use strict; use warnings; package settings; our $foo="hello world"; 1; Below is the main script #!/usr/bin/perl #script.pl use strict; use warnings; use settings; print settings::$foo; It gives this error message instead or printing hello world Bad name after settings:: at ./script.pl line 8.

  • iphone-AVAudio Player Crashes

    - by user2779450
    I have an app that uses an avaudio player for two things. One of them is to play an explosion sound when a uiimageview collision is detected, and the other is to play a lazer sound when a button is pressed. I declared the audioplayer in the .h class, and I call it each time the button is clicked by doing this: NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"/lazer" ofType:@"mp3"]]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; if (error) { NSLog(@"Error in audioPlayer: %@", [error localizedDescription]); } else { [audioPlayer prepareToPlay]; } [audioPlayer play]; This works fine, but after many uses of the game, the audio will stop play when i hit the button, and when a collision is detected, the game crashes. Here is my crash log: 2013-09-18 18:09:19.618 BattleShip[506:907] 18:09:19.617 shm_open failed: "AppleAudioQueue.41.2619" (23) flags=0x2 errno=24 (lldb) Suggestions?

  • No feedback from Socket.SendAsync

    - by BowserKingKoopa
    I'm creating a socket and I'm trying to send data through it using SendAsync. My socket isn't connected to anything so I expected to get an error of some sort. However I get nothing. I get no indication that the send didn't work. If I use the synchronous Send method instead of the asynchronous SendAsync method I get an Exception stating that the socket isn't connected to anything. That makes sense to me. When using SendAsync the completed event doesn't ever fire and I get no indication that the send didn't work. So basically my question is how can I tell when SendAsync fails? Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); SocketAsyncEventArgs args = new SocketAsyncEventArgs(); args.SetBuffer(new byte[0], 0, 0); args.Completed += delegate(object sender, SocketAsyncEventArgs e) { Debug.WriteLine("async send complete"); Debug.WriteLine("SOCKET ERROR: " + e.SocketError); }; bool completedSynchronously = socket.SendAsync(args); if (completedSynchronously) { Debug.WriteLine("sync send complete"); Debug.WriteLine("socket error: " + args.SocketError); }

  • How do I add programmatically-generated new files to source control?

    - by Alex Basson
    This is something I've never really understood about source control, specifically Subversion (the only source control I've ever used, which isn't saying much). I'm considering moving to git or Mercurial, so if that affects the answer to my question, please indicate as such. Ok. As I understand it, every time I create a new file, I have to tell SVN about it, so that it knows to add it to the repository and place it under control. Something like: svn add newfile That's fine if I'm the one creating the file: I know I created it, I know its name, I know where it lives, so it's easy to tell SVN about it. But now suppose I'm using a framework of some kind, like Rails, Django, Symfony, etc., and suppose I've already done the initial commit. All of these frameworks create new files programmatically, often many at once, in different directories, etc. etc. How do I tell the source control about these new files? Do I have to hunt each one of them down individually and add them? Is there an easier way? (Or am I possibly misunderstanding something fundamental about source control?)

  • rapid application developement tools for very basic GUI apps

    - by Jurij
    I know there are many RAD platforms out there. Infact there are so many that I'm having a hard time finding out which one fits me best. What I want is a RAD tool that would allow me to define a database data model (make DB tables) and then create (view and edit) forms for the various tables. Data input, updating and various queries should be easy and GUI should generate automatically. I'd like to add some additional functionality by coding (such as various complex calculations on the data). I'm a programmer so I'm willing to learn to use a more complete, full-blown RAD solution if you can point me to it (NetBeans and RubyOnRails being the two such frameworks that I'd would probably be high on the list). I'm currently doing Windows Forms logistics apps in .NET. I've actually developed a very crude and basic version of what I need, but I just know that there are solutions out there that are much better and I'd benefit by knowing how to use them. So in short, the basic requirements: * database based data storage (SQLite if possible) * very automated GUI creation * desktop based (as in: not a web app) * extendable by coding * used for creating simple data entry, view & query apps. So basically something like Oracle Forms or DotNetMushroom Rapid Application Developer. But for .NET and SQLite if possible.

  • Single Form with Multiple Dynamic Buttons

    - by John Reilly
    I've spent hours/days trying to figure this out and now I'm completely perplexed so I thought I'd give stackoverflow a try. I'm (a newb) working in Java/JSP using Eclipse hosting on Google App Engine trying to develop an app for a volunteer organization I'm a member of. Rather than embarrass myself by showing my current code I'd love just a nudge in the right direction. I have a form (which doubles as a report basically) showing "people" grouped under the "task" they are currently working on. I would like to select multiple people from multiple tasks and reassign them to another task e.g. Bill and Jane are Gardening, Jeff is Painting. I want to select Jane and Jeff (all people have an associated checkbox in the form) and re-assign them to Sweeping (which is a task on the form but has no people assigned to it yet). Ideally, the re-assignment to Sweeping would be via a Sweeping button (each task would have a dynamically-created task button) that would pass the "Sweeping" value to a servlet along with an array or list of people whose checkbox has been checked. The servlet would handle the request (creating an Assignment "object/entity" with timeStamp, personId, taskId) and then re-direct back to the form/report which would then repaint with the current tasks/people generated from the Assignments class in the datastore. All the tasks are user-defined and retrieved from the database when building the form. Ditto the people. I've been trying to keep the jsp for presentation and the servlets for the processing but I'm no purist and would just like to get unstuck. Many thanks in advance for your assistance.

  • In WPF, accessing containers within ListBox

    - by Jim
    I'm creating a DerivedListBox : ListBox and a DerivedHeaderedContentControl : HeaderedContentControl, which will serve as a container for each item in the ListBox. In order to calculate the size available for the expanded content of the DerivedHeaderedContentControls, I am storing each container object in a list within the DerivedListBox. This way I can calculate the height of the headers of each DerivedHeaderedContentControl and subtract that from the total size available to the DerivedListBox. This would be the size available for the expanded content of a DerivedHeaderedContentControl. public class DerivedHeaderedContentControl : HeaderedContentControl { // Do some binding to DerivedListBox to calculate height. } public class DerivedListBox : ListBox { private List<DerivedHeaderedContentControl> containers; protected override DependencyObject GetContainerForItemOverride() { DerivedHeaderedContentControl val = new DerivedHeaderedContentControl(); this.containers.Add(val); return val; } // Do some binding to calculate height available for an expanded // container by iterating over containers. } The problem comes in when the DerivedListBox's ItemsSource is cleared (or an item in the items source is removed). How can I determine when the ItemsSource is cleared so that I can clear the containers list?

  • Getting hardware floating point with android NDK

    - by Goz
    Hi All, I've begun playing with the android NDK. One of the things I've just learnt is about creating an application.mk file to specify the armv7 abi. I'm building the san-angeles example with the following parameters. APP_MODULES := sanangeles APP_PROJECT_PATH := $(call my-dir)/../ APP_OPTIM := release APP_ABI := armeabi-v7a However this seems to run at exactly the same speed as it did before (ie badly). Am I just GL limited and not CPU limited or is something wrong here? I have noticed when I compile that I get the following command line options emitted: -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mthumb The thing that worries me there is the "softfp". There IS mention of the v7 abi, the VFP fpu stuff and I'm guessing the "thumb" refers to the "thumb-2" instructions (Though I don't know what exactly these are). However that "softfp" does concern me. Shouldn't it be "hardfp"? Anyone got any ideas on these questions? I think I'm probably about ready to start implementing some GL ES 2.0 code for my HTC Desire but I'd like to make sure I'm getting the best possible speed out of it :) Cheers in advance!
