• IE AJAX/Jquery issue - redirecting to new page instead of loading it into a div

  - by phx-zs

  I have a page like this: <form class="ajax" method="post" action="add_item.php"> [text input] [submit button] </form> [list any items the user has in a div here called #items] When the user clicks the submit button, a function like this is called: $("form.ajax").live('submit', function(event) { params = $(this).serialize(); $.post($(this).attr("action"), params, function(data){ json = $.parseJSON(data); // do stuff based on the json results if(json.success.action == 'replace'){ $(json.success.container).html(json.success.message); } else{ $(json.success.container).prepend(json.success.message); $(json.success.container).find(".item:first").slideDown(); } }); event.returnValue = false; return false; }); This is supposed to load add_item.php into the #items div, and it works fine in FF, Chrome, Safari, just not IE. In IE (tested 7 and 8) when I click Submit it redirects the page to add_item.php rather than loading it into the #items div. I tried adding event.preventDefault(); to the end of the function but that didn't work. Any ideas?

• Context problem while loading Assemblies via Structuremap

  - by Zebi

  I want to load plugins in a smiliar way as shown here however the loaded assemblies seem not to share the same context. Trying to solve the problem I just build a tiny spike containing two assemblies. One console app and one library. The console app contains the IPlugin interface and has no references to the Plugin dll. I am scanning the plugin dir using a custom Registration convention: ObjectFactory.Initialize(x => x.Scan(s => { s.AssembliesFromPath(@"..\Plugin"); s.With(new PluginScanner()); })); public void Process(Type type, Registry registry) { if (!type.Name.StartsWith("P")) return; var instance = ObjectFactory.GetInstance(type); registry.For<IPlugin>().Add((IPlugin)instance); } Which thows an invalid cast exception saying he can not convert the plugin Type to IPlugin. public class P1 : IPlugin { public void Start() { Console.WriteLine("Hello from P1"); } } Further if I just construct the instance (which works fine by the way) and try to access ObjectFactory in the plugin ObjectFactory.WhatDoIHave() shows that they don't even share the same container instance. Experimenting around with MEF, Structuremap and loading the assembly manually whith Assembly.Load("Plugin") shows if loaded with Assembly.Load it works fine. Any ideas how I can fix this to work with StructureMaps assembly scanning?

• PNG Textures not loading on HTC desire

  - by Matthew Tatum

  Hi I'm developing a game for android using OpenGL es and have hit a problem: My game loads fine in the emulator (windows xp and vista from eclipse), it also loads fine on a T-Mobile G2 (HTC Hero) however when I load it on my new HTC Desire none of the textures appear to load correctly (or at all). I'm suspecting the BitmapFactory.decode method although I have no evidence that that is the problem. All of my textures are power of 2 and JPG textures seem to load (although they don't look great quality) but anything that is GIF or PNG just doesn't load at all except for a 2x2 red square which loads fine and one texture that maps to a 3d object but seems to fill each triangle of the mesh with the nearest colour). This is my code for loading images: AssetManager am = androidContext.getAssets(); BufferedInputStream is = null; try { is = new BufferedInputStream(am.open(fileName)); Bitmap bitmap; bitmap = BitmapFactory.decodeStream(is); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); } catch(IOException e) { Logger.global.log(Level.SEVERE, e.getLocalizedMessage()); } finally { try { is.close(); } catch(Exception e) { // Ignore. } } thanks

• Xcode 4: nib files not loading when run, can't find UI elements

  - by Jordan

  So, I just downloaded Xcode 4 and installed it. I was actually quite looking forward to the single window and integrated IB... - However, when I open and run one of my projects, the nib files that the project uses don't seem to load. Instead I'm left looking at a blank white screen (iPhone). This project ran well and fine on Xcode 3.2. So I thought... this can't be that hard to fix. So I opened up a nib file, thinking that maybe editing or creating a new one from scratch could point me in the right direction. But I can't find the old resources panel from interface builder anywhere. How am I meant to create a new view or add buttons? I know I'm probably just missing something obvious :s Did anyone else have the same nib file problems - is there a fix (or something stupidly simple that I'm forgetting about)? - EDIT: Ok. If I background and un-background the app, the view loads fine. But this happens every time I build, on both iPhone and iOS simulator, i.e. the app doesn't work properly until it's been backgrounded. All the code for loading the view follows from - (void)applicationDidFinishLaunching:(UIApplication *)application. Now I am really confused. - Thanks :)

• Loading a Win32 control in C# (specifically WPF)

  - by Mmarquee

  I have written a set of Win32 dlls that encapsulate a Delphi Frame (see Snippet 1 below), and can load them into another Delphi program by loading the dll and assigning the right variables (Snippet 2). I now want to be able to do the same thing in C# (I can load the DLL in pinvoke, but am unsure how to connect up the control to the basic WPF 'form'. Snippet 1 var frame : TFrame1; function CreateFrame(hParent:TWinControl):Integer; stdcall; export; begin try frame := TFrame1.Create(hParent); frame.Parent := hParent; frame.Align := alClient; finally result := 1; end; end; exports CreateFrame name 'CreateFrame'; Snippet 2 DLLHandle := LoadLibrary('Library/Demo.Frame.dll'); If DLLHandle > 32 then begin ReturnValue := GetProcAddress(DLLHandle, 'CreateFrame'); end; ts1 := TTabSheet.Create(PageControl1); with ts1 do begin PageControl := PageControl1; Name := 'tsExternal'; Caption := 'External'; Align := alClient; ReturnValue (ts1); end; Any help would be greatly appreciated.

• How to lazy load a data structure (python)

  - by Anton Geraschenko

  I have some way of building a data structure (out of some file contents, say): def loadfile(FILE): return # some data structure created from the contents of FILE So I can do things like puppies = loadfile("puppies.csv") # wait for loadfile to work kitties = loadfile("kitties.csv") # wait some more print len(puppies) print puppies[32] In the above example, I wasted a bunch of time actually reading kitties.csv and creating a data structure that I never used. I'd like to avoid that waste without constantly checking if not kitties whenever I want to do something. I'd like to be able to do puppies = lazyload("puppies.csv") # instant kitties = lazyload("kitties.csv") # instant print len(puppies) # wait for loadfile print puppies[32] So if I don't ever try to do anything with kitties, loadfile("kitties.csv") never gets called. Is there some standard way to do this? After playing around with it for a bit, I produced the following solution, which appears to work correctly and is quite brief. Are there some alternatives? Are there drawbacks to using this approach that I should keep in mind? class lazyload: def __init__(self,FILE): self.FILE = FILE self.F = None def __getattr__(self,name): if not self.F: print "loading %s" % self.FILE self.F = loadfile(self.FILE) return object.__getattribute__(self.F, name) What might be even better is if something like this worked: class lazyload: def __init__(self,FILE): self.FILE = FILE def __getattr__(self,name): self = loadfile(self.FILE) # this never gets called again # since self is no longer a # lazyload instance return object.__getattribute__(self, name) But this doesn't work because self is local. It actually ends up calling loadfile every time you do anything.

• Keeping Linq to SQL alive when using ViewModels (ASP.NET MVC)

  - by Kohan

  I have recently started using custom ViewModels (For example, CustomerViewModel) public class CustomerViewModel { public IList<Customer> Customers{ get; set; } public int ProductId{ get; set; } public CustomerViewModel(IList<Customer> customers, int productId) { this.Customers= customers; this.ProductId= productId; } public CustomerViewModel() { } } ... and am now passing them to my view instead of the Entities themselves (for example, var Custs = repository.getAllCusts(id) ) as it seems good practice to do so. The problem i have encountered is that when using ViewModels; by the time it has got to the the view i have lost the ability to lazy load on customers. I do not believe this was the case before using them. Is it possible to retain the ability of Lazy Loading while still using ViewModels? Or do i have to eager load using this method? Thanks, Kohan.

• only default controller is loading for all request - Critical

  - by Jayapal Chandran

  Hi, My codeigniter project is in live. I have two copies of it. One in the root and another in a subfolder. Both are configered to work normal. The root copy if the one which was made after testing in a subfolder. While running from the a subfolder all worked well. But when copied to the root folder the default controller is loading for all requests. But were as in subfolders and in other servers it is working well. It is like the following A true copy in root folder like sitename.com and another true copy in a subfolder like sitename.com/abc when requesting like this sitename.com/gallery the default controller is loaded instead of gallery controller. When i tried like this sitename.com/index.php/gallery/ then it worked well... but sitename.com/gallery/ is showing only the default controller. that is the index page. here is my htaccess... php_flag magic_quotes_gpc off php_flag short_open_tag on RewriteEngine on RewriteCond $1 !^(index\.php|images|css|static|font|xml|flash|galleryimages|htc|store|robots\.txt) RewriteRule ^(.*)$ index.php/$1 [L] The server is Linux barracuda.elinuxservers.com 2.6.27.18-21 #1 SMP Tue Aug 25 18:13:37 UTC 2009 i686 PHP Version 5.2.9

• ipad subview not loading before code is executing

  - by ethan Criss

  I have a command that should be loading a subview before a particular piece of time intensive code executes. However the command runs, the timely code executes and then the subview shows up. Is there anything I can do to fix this problem? progressViewController = [[ProgressView alloc] initWithNibName:@"ProgressView" bundle:[NSBundle mainBundle]]; [self.view addSubview:[progressViewController view]]; NSString *name=@"guy"; NSString *encodedName =[[NSString alloc] init]; int asci; for(int i=0; i < [name length]; i++) { //NSLog(@"1"); asci = [name characterAtIndex:i]; NSString *str = [NSString stringWithFormat:@"%d,", asci]; encodedName =[encodedName stringByAppendingFormat: str]; } NSString *urlString = [NSString stringWithFormat:@"someurl.com"]; NSURL *theUrl = [[NSURL alloc] initWithString:urlString]; NSString *result=[NSString stringWithContentsOfURL:theUrl]; result = [result substringFromIndex:61]; result = [result substringToIndex:[result length] - 20]; NSLog(result); outLab.text=result; [[progressViewController view] removeFromSuperview];

• Stop lazy-loading images?

  - by Greg

  Here's the issue – I followed along with the Apple lazy-load image sample code to handle my graphical tables. It works great. However, my lazy-load image tables are being stacked within a navigation controller so that you can move in and out of menus. While all this works, I'm getting a persistent crash when I move into a table then move immediately back out of it using the "back" button. This appears to be a result of the network connections loading content not being closed properly, or calling back to their released delegates. Now, I've tried working through this and carefully setting all delegates to nil and calling close on all open network connections before releasing a menu. However, I'm still getting the error. Also – short posting my entire application code into this post, I can't really post a specific code snippet that illustrates this situation. I wonder if anyone has ideas for tasks that I may be missing? Do I need to do anything to close a network connection other than closing it and setting it to nil? Also, I'm new to debugging tools – can anyone suggest a good tool to use to watch network connections and see what's causing them to fail? Thanks!

• Windows 2008 and wrong BPL loading [SOLVED]

  - by Beto Neto

  I have an application builded with Run-time Packages. When the executable starts it auto loads the required packages (.bpl). Recently we has installed an Windows 2008 R2 server to use as Terminal Services. We maintain some old compiled versions of our application in different paths, like this: c:\app\version_1\common.bpl c:\app\version_1\app.exe c:\app\version_2\common.bpl c:\app\version_2\app.exe Common.bpl is the a run-time package what app.exe depends on. THE PROBLEM: I start "c:\app\version_2\app.exe" and it loads "c:\app\version_2\common.bpl". When I start the "c:\app\version_1\app.exe" it loads the WRONG bpl (from version_2). The path "c:\app\version_2\" isn't at the system search path. At Windows2003 server this problem doesn't occurs. What can I do to solve this? Thanks! I have downloaded the Process Explorer (microsoft sysinternals), and checked the loaded modules of each executable, all they are correct! But I noticed another problem. After start the second version, an entry-not-found-error occurs, telling me what a initialization entry point, of an unit what only exists in one of the versions, could not be found. Something is very strange. The ProcessExplorer is telling me that the process is loading the correct modoles, but when they are running this seems not be happening. Seems the applications are sharing the loaded modules. SOLVED There was a MouseHook using FindVCLWindow, this was generating the AV. Sorry about inconvenience guys, and thanks!

• Appending facts into an existing prolog file.

  - by vuj

  Hi, I'm having trouble inserting facts into an existing prolog file, without overwriting the original contents. Suppose I have a file test.pl: :- dynamic born/2. born(john,london). born(tim,manchester). If I load this in prolog, and I assert more facts: | ?- assert(born(laura,kent)). yes I'm aware I can save this by doing: |?- tell('test.pl'),listing(born/2),told. Which works but test.pl now only contains the facts, not the ":- dynamic born/2": born(john,london). born(tim,manchester). born(laura,kent). This is problematic because if I reload this file, I won't be able to insert anymore facts into test.pl because ":- dynamic born/2." doesn't exist anymore. I read somewhere that, I could do: append('test.pl'),listing(born/2),told. which should just append to the end of the file, however, I get the following error: ! Existence error in user:append/1 ! procedure user:append/1 does not exist ! goal: user:append('test.pl') Btw, I'm using Sicstus prolog. Does this make a difference? Thanks!

• Call a dynamically generated method on a ILGenerator on the same type

  - by Thiado de Arruda

  Normally, when I want to call a dynamic method in another ILGenerator object that is writing a method on the same type I do the following : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, methodBuilder); //this methodbuilder is also defined on this dynamic type. However, I faced the following problem: I cant have a reference to the methodbuilder of the method I want to call, because it is generated by another framework(I only get a reference to the current TypeBuilder). This method is defined as protected virtual(and overriden on the methodbuilder I cant get a reference to) in the base class of the current dynamic type and I can get a reference to it by doing this : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, baseType.GetMethod("SomeMethodDefinedInBaseClassThatWasOverridenInThisDynamicType")); The problem is that this calls the method on the base type and not the overriden method. Is there any way I can get a reference to a methodbuilder only having a reference to the typebuilder that defined it? Or is there a way to call a method using ILGenerator without having to pass the 'MethodInfo' object to it?

• Custom/personal dyndns solution?

  - by Eddie Parker

  Hey: I can't think of how to make this work, but it seems like something that should be doable.. I currently own my own domain, and have been using dyndns.com's "custom DNS" to allow me to redirect 'example.com' to my website at home, which is on a dynamic IP. I've now switched over to a VPS solution which hosts my website and allows me root access to a box (me likey), which will now host "example.com" on a static IP. My question is, is it possible for me to somehow make "home.example.com" route to my box at home? Is there any software available that could automate updates to the DNS for this? Ideally I'd like not to pay a service if possible, but if that's the only way then I suppose I'll have to go that way. Thanks!

• Slow draw on some apps and dynamic clocks not working properly with ATI/AMD proprietary drivers

  - by Rakeka

  I've recently purchased a new computer (around July 2010) and I've been having some problems with proprietary video drivers on Linux. The hardware is: Video: ATI/AMD Radeon HD 5870 (XFX HD-587X-ZNFC); Motherboard: Asus P7P55D-E Deluxe; Processor: Intel i5 750; Memory: Kingston Hyperx KHX1600C8D3K2/4GX (2x - 8GB Total); Power Supply: XFX P1-750B-CAG9; There are no overclocks, not even the memories (they are at 1333mhz due processor memory controller limitation). The operational system is a homebrew Linux distribution with the following software: Architecture: x86_64 (multilib) Kernel: 2.6.35.10 Xorg: 7.5 Window Manager: wmii-3.9.2 Video Driver: ATI/AMD Catalyst 10.12 There are no desktop effects programs like compiz fusion or beryl. The problems: With ATI/AMD proprietary driver, some applications are with slow draw/redraw, and, the same applications make the driver to increase the card clocks to maximum (0% gpu activity, only the clocks are increased). I dunno exactly how to describe the slow draw but I'll list some applications and symptoms. xterm Flickers a lot when drawing continuous output; When I'm in a workspace with fullscreen xterm, The gpu load stays at 12% in idle, and, with smaller xterm, smaller GPU load. "aticonfig --odgc" output: Default Adapter - ATI Radeon HD 5800 Series Core (MHz) Memory (MHz) Current Clocks : 157 300 Current Peak : 850 1200 Configurable Peak Range : [600-900] [900-1300] GPU load : 12% "aticonfig --pplib-cmd 'get activity'" output: Current Activity is Core Clock: 157MHZ Memory Clock: 300MHZ VDDC: 950 Activity: 12 percent Performance Level: 0 Bus Speed: 5000 Bus Lanes: 16 Maximum Bus Lanes: 16 More examples: mplayer time info flickers on terminal; "find /" flickers a lot (It takes some time to stop with control-c. But, If I change the workspace or put some window upon it, just after the control-c, it stops instantly); "cat somefile" if the file is big (Xorg.0.log for example) it takes some time to display; vim and less (ex: find / | less) don't have much problems, just a little flicker when scrolling; mplayer (no gui) Slow reproduction and seek with -vo x11; Tearing with -vo xv; Time info flickers on terminal (xterm consequence); gvim A little slow draw when scrolling with page up/page down; Firefox Slow draw/redraw on some pages like www.boadica.com.br and sometimes on www.youtube.com with flash enable (never noticed on many pages); Corruptions when informative yellow boxes are showing and scroll the page (an gray box appears at the same place of the informative box); "Wallpaper" After minimizing a fullscreen window or changing to an empty workspace it takes some time to redraw wallpaper. "Video Card" The core and memory clocks are increased with the events described above and on other situations like change workspace (even without wallpaper), minimize, maximize or move a window; Idle clocks: Core: 157mhz, Memory: 300mhz Full clocks: Core: 850mhz, Memory: 1200mhz xpdf Painful slow scrolling; display (from ImageMagick) Slow menus and sometimes slow image redraw; Programs that I use and are apparently without problems: gimp; pidgin; mplayer (-vo gl, gl2); blender; unigine heaven (better fps than on Windows); doom3; tibia; penumbra overture; amnesia the dark descent (wine); diablo 2 (wine); No problems on Windows (Windows 7 Ultimate 64bit). And special note to this: Full desktop effects from Debian and Ubuntu gnome appearance cpanel don't cause ANY problems, even the core and memory clocks don't increase when change workspace, minimize, maximize or move a window. What I've tested: Unsuccessful tests: Tested all drivers versions since 10.6 (released approximately when I've installed the first slackware in this PC); Tested other video card - ATI/AMD Radeon HD 5570 (XFX HD-557X-ZHF2); Tested some options on xorg.conf and that I've found googling (some of these options are commented on my xorg.conf. I'll send the links at the end of post); Tested some patches like 107_fedora_dont_fill_bg_none.patch and xserver-xorg-backclear.patch from Arch Linux Catalyst page (https://wiki.archlinux.org/index.php/ATI_Catalyst); Tested other distros and software versions: Tested XORG-7.6 on my own distribution; Tested Debian Squeeze (testing - from 2010-12-20); Tested Ubuntu Marverick (10.10); Tested Slackware 13.1; Distros info: Architecture: i386 Debian and Ubuntu with all default software (kernel, gnome, xorg, drivers); Slackware with Catalyst from AMD page and default window managers like: fvwm, xfce, and my own build of wmii; Successful tests: Tested other video card (only on my homebrew distro) - NVIDIA Geforce 7300GS with driver 260.19.29; That didn't shown the slow draw problems, but that card is a bit obsolete, so, dunno if that lacks features like the dynamic clocks. I don't dispose of other video cards like nvidia g/gt/gts/gtx 200~400~500 or Radeon HD 3000/4000/6000 to make more tests. Tested other hardware: Video: ATI/AMD Radeon HD 5570 (XFX HD-557X-ZHF2); Motherboard: Intel DG31PR; Processor: Core 2 Duo E6750; Software for that hardware: Fresh install of same distros (except for the mine) with same program versions; That video card (HD 5570) were full time at the maximum clocks (something like 500/750, don't remember) in all the operational systems (Windows XP and Windows 7 too), but it didn't shown the same problems that I have here. I've googled a lot about common problems with ATI/AMD proprietary drivers for Linux and didn't find similar problems, except by the Firefox corruptions, that the solutions were to disable ATI Direct2DAccel and use XAA. With XAA the problems persists and the other applications like pidgin and rest of Firefox showed the same problems of slow draw/redraw. Open source Drivers: With open source drivers (xf86-video-ati-6.13.2) I hadn't the same slow draw problems, but, had other problems, that, for now, make it no viable solution. I'll not discuss it here because this is another line of problems and will confuse everything. If it happens to be the only solution, I'll make another thread to discuss it. Logs and Configs: kernel .config dmesg xorg package list xorg.conf Xorg.0.log

• Access device with local ip over internet

  - by Joe Perrin

  I apologize up front if this is the wrong place to post this question. It seemed like the best fit. I have a device which is connected to my local network which has an IP of 192.168.1.10 from my router. Additionally I use a Windows 7 machine that runs some software called DirectUpdate which allows me to resolve the local IP of the Windows 7 machine (192.168.1.5) to be accessible to the internet via my domain (example.com) - Basic dynamic DNS updating. I'd like to access the device from example.com. I am unsure how to do this as I don't have any way to install DirectUpdate (or any software) on the device to make the device available to the internet. Any insight here would be appreciated. Thank you.

• Can I proxy my no-ip domain using a .htaccess file on my hosted domain?

  - by Dean

  I have a domain http://www.example.com which has a hosting package and website on it. I also have a http://example.no-ip.org domain which contains some content I would like to appear under the same domain. Can I setup a .htaccess file at http://www.example.com/proxy/ which proxies the files at http://www.example.no-ip.org/files/ Similarly, could I host an entire domain in the same way?, e.g. http://www.example2.com/ proxying http://example.no-ip.org/files2/ Alternatively, if someone were to say "That's stupid, use this free (or super-cheap) dynamic DNS host:" I would probably accept that answer.

• Asp.Net MVC - Rob Conery's LazyList - Count() or Count

  - by Adam

  I'm trying to create an html table for order logs for customers. A customer is defined as (I've left out a lot of stuff): public class Customer { public LazyList<Order> Orders { get; set; } } The LazyList is set when fetching a Customer: public Customer GetCustomer(int custID) { Customer c = ... c.Orders = new LazyList<Order>(_repository.GetOrders().ByOrderID(custID)); return c; } The order log model: public class OrderLogTableModel { public OrderLogTableModel(LazyList<Order> orders) { Orders = orders; Page = 0; PageSize = 25; } public LazyList<Order> Orders { get; set; } public int Page { get; set; } public int PageSize { get; set; } } and I pass in the customer.Orders after loading a customer. Now the log i'm trying to make, looks something like: <table> <tbody> <% int rowCount = ViewData.Model.Orders.Count(); int innerRows = rowCount - (ViewData.Model.Page * ViewData.Model.PageSize); foreach (Order order in ViewData.Model.Orders.OrderByDescending(x => x.StartDateTime) .Take(innerRows).OrderBy(x => x.StartDateTime) .Take(ViewData.Model.PageSize)) { %> <tr> <td> <%= order.ID %> </td> </tr> <% } %> </tbody> </table> Which works fine. But the problem is evaluating ViewData.Model.Orders.Count() literally takes about 10 minutes. I've tried with the ViewData.Model.Orders.Count property instead, and the results are the same - takes forever. I've also tried calling _repository.GetOrders().ByCustomerID(custID).Count() directly from the view and that executes perfectly within a few ms. Can anybody see any reason why using the LazyList to get a simple count would take so long? It seems like its trying to iterate through the list when getting a simple count.

• Dojo JsonRest store and dijit.Tree

  I'm having a some problem making JSonRest store and dijit.Tree with ForestModel. I've tried some combination of JsonRestStore and json data format following many tips on the web, with no success. At the end, taking example form here http://blog.respondify.se/2011/09/using-dijit-tree-with-the-new-dojo-object-store/ I've made up this simple page (I'm using dojotolkit 1.7.2) <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Tree Model Explorer</title> <script type="text/javascript"> djConfig = { parseOnLoad : true, isDebug : true, } </script> <script type="text/javascript" djConfig="parseOnLoad: true" src="lib/dojo/dojo.js"></script> <script type="text/javascript"> dojo.require("dojo.parser"); dojo.require("dijit.Tree"); dojo.require("dojo.store.JsonRest"); dojo.require("dojo.data.ObjectStore"); dojo.require("dijit.tree.ForestStoreModel"); dojo.addOnLoad(function() { var objectStore = new dojo.store.JsonRest({ target : "test.json", labelAttribute : "name", idAttribute: "id" }); var dataStore = new dojo.data.ObjectStore({ objectStore : objectStore }); var treeModel = new dijit.tree.ForestStoreModel({ store : dataStore, deferItemLoadingUntilExpand : true, rootLabel : "Subjects", query : { "id" : "*" }, childrenAttrs : [ "children" ] }); var tree = new dijit.Tree({ model : treeModel }, 'treeNode'); tree.startup(); }); </script> </head> <body> <div id="treeNode"></div> </body> </html> My rest service responds the following json { data: [ { "id": "PippoId", "name": "Pippo", "children": [] }, { "id": "PlutoId", "name": "Pluto", "children": [] }, { "id": "PaperinoId", "name": "Paperino", "children": [] } ]} I've tried also with the following response (actually my final intention n is to use lazy loading for the tree) { data: [ { "id": "PippoId", "name": "Pippo", "$ref": "author0", "children": true }, { "id": "PlutoId", "name": "Pluto", "$ref": "author1", "children": true }, { "id": "PaperinoId", "name": "Paperino", "$ref": "author2", "children": true } ]} Neither of the two works. I see no error message in firebug. I simply see the root "Subject" on the page. Thanks to anybody could help in some way.

• UIViewController not loading a UIView

  - by Cosizzle

  Hey, I'm playing around with a script my teacher provided for a table based application. However I can't seem to get my own view to load. Files: SubViewOneController (which is a sub view, also has a nib) TapViewController (Custom UIView I created and want to add to a cell) RootViewController (Main controller which loads in the views) SimpleNavAppDelegate How it works: Within the RootViewController, there's an NSArray that holds NSDictionary objects which is declared in the -(void)awakeFromNib {} method - (void)awakeFromNib { // we'll keep track of our views controllers in this array views = [[NSMutableArray alloc] init]; // when using alloc you are responsible for it, and you will have to release it. // ==================================================================================================== // ==================================================================================================== // LOADING IN CUSTOM VIEW HERE: // allocate a set of views and add to our view array as a dictionary item TapViewController *tapBoardView = [[TapViewController alloc] init]; //push onto array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Tab Gestures", @"title", tapBoardView, @"controller", nil]]; [tapBoardView release]; //release the memory // ==================================================================================================== // ==================================================================================================== SubViewOneController *subViewOneController = [[SubViewOneController alloc] init]; // This will set the 2nd level title subViewOneController.title = @"Swipe Gestures"; //set it's title //push it onto the array [views addObject:[NSDictionary dictionaryWithObjectsAndKeys: @"Swipe Gestures", @"title", subViewOneController, @"controller", nil]]; [subViewOneController release]; //release the memory } Later on I set the table view: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // OUTPUT -- see console NSLog(@"indexPath %i", indexPath.row); // OUTPUT: tapController: <TapViewController: 0x3b2b360> NSLog(@"view object: %@", [views objectAtIndex:indexPath.row]); // OUTPUT: view object: controller = <TapViewController: 0x3b0e290>; title = "Tab Gestures"; // ----- Hardcoding the controller and nib file in does work, so it's not a linkage issue ------ // UNCOMMENT TO SEE WORKING -- comment below section. //TapViewController *tapContoller = [[TapViewController alloc] initWithNibName:@"TapBoardView" bundle:nil]; //NSLog(@"tapController: %@", tapContoller); //[self.navigationController pushViewController:tapContoller animated:YES]; // ----- Random Tests ----- //UIViewController *targetViewController = [[views objectAtIndex: 0] objectForKey:@"controller"]; // DOES NOT WORK // LOADS THE SECOND CELL (SubViewOneController) however will not load (TapViewController) UIViewController *targetViewController = [[views objectAtIndex: indexPath.row] objectForKey:@"controller"]; NSLog(@"target: %@", targetViewController); // OUTPUT: target: <TapViewController: 0x3b0e290> [self.navigationController pushViewController:targetViewController animated:YES]; } Reading the comments you should be able to see that hardcoding the view in, works - however trying to load it from the View NSArray does not work. It does however contain the object in memory, seeing that NSLog proves that. Everything is linked up and working within the TapViewController nib file. So ya, im kinda stuck on this one, any help would be great! Thanks guys

• Loading, listing, and using R Modules and Functions in PL/R

  - by Dave Jarvis

  I am having difficulty with: Listing the R packages and functions available to PostgreSQL. Installing a package (such as Kendall) for use with PL/R Calling an R function within PostgreSQL Listing Available R Packages Q.1. How do you find out what R modules have been loaded? SELECT * FROM r_typenames(); That shows the types that are available, but what about checking if Kendall( X, Y ) is loaded? For example, the documentation shows: CREATE TABLE plr_modules ( modseq int4, modsrc text ); That seems to allow inserting records to dictate that Kendall is to be loaded, but the following code doesn't explain, syntactically, how to ensure that it gets loaded: INSERT INTO plr_modules VALUES (0, 'pg.test.module.load <-function(msg) {print(msg)}'); Q.2. What would the above line look like if you were trying to load Kendall? Q.3. Is it applicable? Installing R Packages Using the "synaptic" package manager the following packages have been installed: r-base r-base-core r-base-dev r-base-html r-base-latex r-cran-acepack r-cran-boot r-cran-car r-cran-chron r-cran-cluster r-cran-codetools r-cran-design r-cran-foreign r-cran-hmisc r-cran-kernsmooth r-cran-lattice r-cran-matrix r-cran-mgcv r-cran-nlme r-cran-quadprog r-cran-robustbase r-cran-rpart r-cran-survival r-cran-vr r-recommended Q.4. How do I know if Kendall is in there? Q.5. If it isn't, how do I find out what package it is in? Q.6. If it isn't in a package suitable for installing with apt-get (aptitude, synaptic, dpkg, what have you), how do I go about installing it on Ubuntu? Q.7. Where are the installation steps documented? Calling R Functions I have the following code: EXECUTE 'SELECT ' 'regr_slope( amount, year_taken ),' 'regr_intercept( amount, year_taken ),' 'corr( amount, year_taken ),' 'sum( measurements ) AS total_measurements ' 'FROM temp_regression' INTO STRICT slope, intercept, correlation, total_measurements; This code calls the PostgreSQL function corr to calculate Pearson's correlation over the data. Ideally, I'd like to do the following (by switching corr for plr_kendall): EXECUTE 'SELECT ' 'regr_slope( amount, year_taken ),' 'regr_intercept( amount, year_taken ),' 'plr_kendall( amount, year_taken ),' 'sum( measurements ) AS total_measurements ' 'FROM temp_regression' INTO STRICT slope, intercept, correlation, total_measurements; Q.8. Do I have to write plr_kendall myself? Q.9. Where can I find a simple example that walks through: Loading an R module into PG. Writing a PG wrapper for the desired R function. Calling the PG wrapper from a SELECT. For example, would the last two steps look like: create or replace function plr_kendall( _float8, _float8 ) returns float as ' agg_kendall(arg1, arg2) ' language 'plr'; CREATE AGGREGATE agg_kendall ( sfunc = plr_array_accum, basetype = float8, -- ??? stype = _float8, -- ??? finalfunc = plr_kendall ); And then the SELECT as above? Thank you!

• ISQLQuery using AddJoin not loading related instance

  - by Remi Despres-Smyth

  I've got a problem using an ISQLQuery with an AddJoin. The entity I'm trying to return is RegionalFees, which has a composite-id which includes a Province instance. (This is the the instance being improperly loaded.) Here's the mapping: <class name="Project.RegionalFees, Project" table="tblRegionalFees"> <composite-id name="Id" class="Project.RegionalFeesId, project" unsaved-value="any" access="property"> <key-many-to-one class="Project.Province, Project" name="Region" access="property" column="provinceId" not-found="exception" /> <key-property name="StartDate" access="property" column="startDate" type="DateTime" /> </composite-id> <property name="SomeFee" column="someFee" type="Decimal" /> <property name="SomeOtherFee" column="someOtherFee" type="Decimal" /> <!-- Other unrelated stuff --> </class> <class name="Project.Province, Project" table="trefProvince" mutable="false"> <id name="Id" column="provinceId" type="Int64" unsaved-value="0"> <generator class="identity" /> </id> <property name="Code" column="code" access="nosetter.pascalcase-m-underscore" /> <property name="Label" column="label" access="nosetter.pascalcase-m-underscore" /> </class> Here's my query method: public IEnumerable<RegionalFees> GetRegionalFees() { // Using an ISQLQuery cause there doesn't appear to be an equivalent of // the SQL HAVING clause, which would be optimal for loading this set const String qryStr = "SELECT * " + "FROM tblRegionalFees INNER JOIN trefProvince " + "ON tblRegionalFees.provinceId=trefProvince.provinceId " + "WHERE EXISTS ( " + "SELECT provinceId, MAX(startDate) AS MostRecentFeesDate " + "FROM tblRegionalFees InnerRF " + "WHERE tblRegionalFees.provinceId=InnerRF.provinceId " + "AND startDate <= ? " + "GROUP BY provinceId " + "HAVING tblRegionalFees.startDate=MAX(startDate))"; var qry = NHibernateSessionManager.Instance.GetSession().CreateSQLQuery(qryStr); qry.SetDateTime(0, DateTime.Now); qry.AddEntity("RegFees", typeof(RegionalFees)); qry.AddJoin("Region", "RegFees.Id.Region"); return qry.List<RegionalFees>(); } The odd behavior here is that when I call GetRegionalFees (whose goal is to load just the most recent fee instances per region), it all loads fine if the Province instance is a proxy. If, however, Province is not loaded as a transparent proxy, the Province instance which is part of RegionalFees' RegionalFeesId property has null Code and Region values, although the Id value is set correctly. It looks to me like I have a problem in how I'm joining the Province class - since if it's lazy loaded the id is set from tblRegionalFees, and it gets loaded independently afterwards - but I haven't been able to figure out the solution.

• CellTable + AsyncListViewAdapter<T> + SimplePager<T>, stuck with 'loading' bar when paging

  - by Jaroslav Záruba

  Hi I'm trying to make CellTable, AsyncListViewAdapter<T> and SimplePager<T> working together. I managed to display my data, but whenever I click either "go to start" or "go to end" button I get that 'loading' indicator which stays there till the end of days. (And AsyncListViewAdapter<T>.onRangeChanged doesn't even get called this time.) I went through the code-snippets in this thread, but I can't see nothing suspicions in what I've been doing. Is there some obvious answer to a rookie mistake? I shrinked my variable names, hopefully it won't wrap too much. protected class MyAsyncAdapter extends AsyncListViewAdapter<DTO> { @Override protected void onRangeChanged(ListView<DTO> v) { // doesn't get called on go2start/go2end :( Range r = v.getRange(); fetchData(r.getStart(), r.getLength()); } } private void addTable() { // table: CellTable<DTO> table = new CellTable<DTO>(10); table.addColumn(new Column<DTO, String>(new TextCell()) { @Override public String getValue(DTO namespace) { return namespace.getName(); } }, "Name"); // pager: SimplePager<DTO> pager = new SimplePager<DTO>(table); table.setPager(pager); adapter = new MyAsyncAdapter(); adapter.addView(table); // does not make any difference: // adapter.updateDataSize(0, false); // adapter.updateDataSize(10, true); VerticalPanel vPanel = new VerticalPanel(); vPanel.add(table); vPanel.add(pager); RootLayoutPanel.get().add(vPanel); } // success-handler of my fetching AsyncCallback @Override public void onSuccess(List<DTO> data) { // AsyncCallback<List<DTO>> has start field adapter.updateViewData(start, data.size(), data); if(data.size() < length) adapter.updateDataSize(start + data.size(), true); } Regards J. Záruba
