  • Telerik MVC Grid won't load data into details table (subtable)

    - by henriksen
    I have a list of Plants and assosiated Projects. I want to output this in a table with all the Plants and use Telerik.Grid to expand a Plant, show a Telerik.Grid with associated Projects. I want the Projects to be dynamically loaded with Ajax. The code for the grid: @(Html.Telerik().Grid<PlantDto>() .Name("Plants") .Columns(columns => { columns.Bound(plant => plant.Title); }) .DetailView(details => details.ClientTemplate( Html.Telerik().Grid<ProjectDto>() .Name("Plant_<#= Id #>") .DataBinding(dataBinding => dataBinding.Ajax() .Select("ProjectsForPlant", "User", new { plantId = "<#= Id #>" })) .ToHtmlString() )) .DataBinding(dataBinding => dataBinding.Ajax().Select("PlantsForUser", "User")) ) The initial data is loaded into the grid just fine (the list of Plants) but when I expand a plant I just get an empty sub-table. Looking in FireBug there are no calls to the server. The controller that should serve the list of projects is never called. Anyone have an idea on what it could be?

  • How safe and reliable are C++ String Literals?

    - by DoctorT
    So, I'm wanting to get a better grasp on how string literals in C++ work. I'm mostly concerned with situations where you're assigning the address of a string literal to a pointer, and passing it around. For example: char* advice = "Don't stick your hands in the toaster."; Now lets say I just pass this string around by copying pointers for the duration of the program. Sure, it's probably not a good idea, but I'm curious what would actually be going on behind the scenes. For another example, let's say we make a function that returns a string literal: char* foo() { // function does does stuff return "Yikes!"; // somebody's feeble attempt at an error message } Now lets say this function is called very often, and the string literal is only used about half the time it's called: // situation #1: it's just randomly called without heed to the return value foo(); // situation #2: the returned string is kept and used for who knows how long char* retVal = foo(); In the first situation, what's actually happening? Is the string just created but not used, and never deallocated? In the second situation, is the string going to be maintained as long as the user finds need for it? What happens when it isn't needed anymore... will that memory be freed up then (assuming nothing points to that space anymore)? Don't get me wrong, I'm not planning on using string literals like this. I'm planning on using a container to keep my strings in check (probably std::string). I'm mostly just wanting to know if these situations could cause problems either for memory management or corrupted data.

  • VB dataset issue

    - by Gabriel
    Hi. The idea was to create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset ds2. I've tried my Query on my SQL and it works perfectly so I really really need help to spot the error in my chunk of codes here. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim name As String Dim icn As String Dim message As String Dim time As String Dim tags As String = "" Dim strConn As System.Configuration.ConnectionStringSettings strConn = ConfigurationManager.ConnectionStrings("ufadb") Dim conn As SqlConnection = New SqlConnection(strConn.ToString()) Dim cmd As New SqlCommand("Select * From Message", conn) Dim daMessages As SqlDataAdapter = New SqlDataAdapter(cmd) Dim ds As New DataSet cmd.Connection.Open() daMessages.Fill(ds, "Messages") cmd.Connection.Close() If ds.Tables("Messages").Rows.Count > 0 Then Dim n As Integer = ds.Tables("Messages").Rows.Count Dim i As Integer For i = 0 To n - 1 icn = ds.Tables("Messages").Rows(i).Item("icn") Dim cmd2 As New SqlCommand("SELECT name FROM Member inner join Message ON Member.icn = Message.icn WHERE message.icn = @icn", conn) cmd2.Parameters.AddWithValue("@icn", icn) Dim daName As SqlDataAdapter = New SqlDataAdapter(cmd2) Dim ds2 As New DataSet cmd2.Connection.Open() daName.Fill(ds2, "PosterName") cmd2.Connection.Close() name = ds2.Tables("PosterName").Rows(0).Item("name") message = ds.Tables("Messages").Rows(i).Item("message") time = ds.Tables("Messages").Rows(i).Item("timePosted") tags = time + vbCrLf + name + ": " + vbCrLf + message + vbCrLf + tags Next txtBoard.Text = tags Else txtBoard.Text = "nothing to display" End If End Sub Help will be very much appreciated as I have been on this simple problem for 2 days.

  • IE "Microsoft JScript runtime error: Object expected"

    - by Stephen Borg
    Hi there, I have problems with regards to javascript only when using IE. The error I am getting is "Microsoft JScript runtime error: Object expected" and I have no idea why. It is then jumping into the JQuery 1.4.2 file, without giving me a proper error message. All I am doing is simply reading on page load the raw URL, and getting a query string named Search. Using that in an AJAX call to return products and put then into a DIV. No biggies, but somehow IE is managing to blow my page up :-( Any ideas? Code as follows : <script type="text/javascript"> $(document).ready(function (e) { $('.boxLoader').show(); function getParameterByName(name) { name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regexS = "[\\?&]" + name + "=([^&#]*)"; var regex = new RegExp(regexS); var results = regex.exec(window.location.href); if (results == null) return ""; else return decodeURIComponent(results[1].replace(/\+/g, " ")); } var Search; Search = getParameterByName("search"); $('#searchCriteria').text(Search); $.get("/Handlers/processProducts.aspx", { SearchCriteria: Search }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); $('#searchBox').live("click", function () { $.get("/Handlers/processProducts.aspx", { SearchCriteria: $('#searchCriteria').val() }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); }); }); </script>

  • Android Signal analysis + some filters.

    - by Profete162
    Hello, as the world cup is the main sport event and the Vuvuzelas are the most annoying sound in the world, I had an idea to remove them definitively by reading this new ( http://www.popsci.com/diy/article/2010-06/simple-software-can-filter-out-vuvuzela-whine) that told us that the sound has some frequencies at 233Hz + 466,932,1864Hz. I have already made a lot of Android application by myself but never touching the signal analysis and filtering part, so here are a few questions, I do not ask for precise answer but maybe links and tutorial to find something to work on. I guess that a new Android phone has the CPU and power to make real-time filtering. 1) How can I intercept the sound coming from the Jack microphone - Line-IN plug- ( I plan to link my TV to my phone with Jack to Jack plug). My question is totally software and coding, I have all the wires and adapters to plug a jack into my android phone Line IN. 2) Are there some Fourier analysis librairies, may I have a look to Java libraries on the web and import them to my Android project? I really apologize because my question seem not precise, but I think that would be something great. Thank you for your answers.

  • How to redirect registry access of a dll loaded by my program

    - by dummzeuch
    I have got a dll that I load in my program which reads and writes its settings to the registry (hkcu). My program changes these settings prior to loading the dll so it uses the settings my program wants it to use which works fine. Unfortunately I need to run several instances of my program with different settings for the dll. Now the approach I have used so far no longer works reliably because it is possible for one instance of the program to overwrite the settings that another instance just wrote before the dll has a chance to read them. I haven't got the source of the dll in question and I cannot ask the programmer who wrote it to change it. One idea I had, was to hook registry access functions and redirect them to a different branch of the registry which is specific to the instance of my program (e.g. use the process id as part of the path). I think this should work but maybe you have got a different / more elegant. In case it matters: I am using Delphi 2007 for my program, the dll is probably written in C or C++.

  • Is there any danger in committing to a component library such as SmartGwt or Swing?

    - by Banang
    Since February this year I have been working on an app that's built using SmartGWT components. Generally, I find the components very nice to work with, and the fact that they're open source and free to use is just fantastic. However, I can't seem to shake the feeling that it's not a durable way of developing, but I can't quite explain why. Maybe it's because I know that any minute now the team developing it could decide to stop, which would leave me and my team in a bit of a pickle, but I'm sure there must be something more. I have been trying to find ways of explaining this feeling to myself, but to no avail. Therefore I turn to you, dear community, to ask if you can come up with a good reason why committing to building your app (that's supposed to be around for many more years to come) using a component library such as SmartGWT is a bad idea? Is there any reason I should just have developed the components myself? Or did I make the right choice when deciding not to reinvent the wheel and just go for what was readily available?

  • How can someone with no experience learn how to program?

    - by Mugatu
    A friend and I have been coming up with website ideas for a couple years, mostly just jotting them down whenever we come up with a good, useful idea when browsing the web. For the past 6 months we've hired a couple different programmers to make a couple of the sites for us, but have been disappointed with how it's gone. Been too slow and too many miscommunications for our liking. So like the saying goes if you want something done right do it yourself, we're going to do it ourselves. I know nothing about programming, I've never written a line of code in my life. I consider myself very good with math and about as logical as you can get, but I have zero real-life programming knowledge. The sites we want to make are all pretty 'Web 2.0'ish', meaning user-generated content, commenting on posts, pages that change on the fly, etc. So here are some of my questions for anyone who's been there before: Is there a language you'd recommend learning first? Something that is a good indicator how most other languages work? What web programming languages do you recommend learning first based on popularity both now and the future. I don't want to learn a language that's going to be outdated by the time I'm an expert at it. Any specific books you'd recommend? Any general advice you'd give to someone literally starting at square zero for coding who plans on being in it for the long haul?

  • Midiplayer stops playing sounds after 16 notes.

    - by user349673
    Hi. I am currently programming a Piano Keyboard editor, much like the one you can find in Cubase, Logic, Reason etc.. I have this big grid, double array new int [13][9], which makes it 13 rows, 9 columns. The first column [0-12][0] is the Keyboard, at the top there's "high C" (midi note 72) and at the bottom there's "low C" (midi note 60). That column is an array of JButtons and when you press for example "low C", note 60 is being played by the Synthesizer. I've gotten this to work pretty OK as for now, but one problem I have is that I can only play 16 notes in a row, then it's like the Synthesizer shuts down or something. Do you guys have ANY idea of what the problem is? A bit of the code: import java.awt.*; import javax.swing.*; import java.awt.event.*; import java.util.*; import javax.sound.midi.*; actionPerformed(ActionEvent ae){ for(int i = 0; i<13; i++){ if(o== instr[i]){//instr is the button array SpelaTangent(i); } } } public void SpelaTangent(int tangent){ int [] klaviatur = new int[13]; for(int i = 0; i<13; i++){ klaviatur[i] = (72-i); } try { Synthesizer synth = MidiSystem.getSynthesizer(); synth.open(); final MidiChannel[] mc = synth.getChannels(); Instrument[] instrument = synth.getDefaultSoundbank().getInstruments(); synth.loadInstrument(instrument[1]); mc[0].noteOn(klaviatur[tangent],350); mc[0].noteOff(klaviatur[tangent],350); } catch (MidiUnavailableException e) {} } Help is very much appreciated!

  • NSOperations or NSThread for bursts of smaller tasks that continuously cancel each other?

    - by RickiG
    Hi I would like to see if I can make a "search as you type" implementation, against a web service, that is optimized enough for it to run on an iPhone. The idea is that the user starts typing a word; "Foo", after each new letter I wait XXX ms. to see if they type another letter, if they don't, I call the web service using the word as a parameter. The web service call and the subsequent parsing of the result I would like to move to a different thread. I have written a simple SearchWebService class, it has only one public method: - (void) searchFor:(NSString*) str; This method tests if a search is already in progress (the user has had a XXX ms. delay in their typing) and subsequently stops that search and starts a new one. When a result is ready a delegate method is called: - (NSArray*) resultsReady; I can't figure out how to get this functionality 'threaded'. If I keep spawning new threads each time a user has a XXX ms. delay in the typing I end up in a bad spot with many threads, especially because I don't need any other search, but the last one. Instead of spawning threads continuously, I have tried keeping one thread running in the background all the time by: - (void) keepRunning { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; SearchWebService *searchObj = [[SearchWebService alloc] init]; [[NSRunLoop currentRunLoop] run]; //keeps it alive [searchObj release]; [pool release]; } But I can't figure out how to access the "searchFor" method in the "searchObj" object, so the above code works and keeps running. I just can't message the searchObj or retrieve the resultReady objects? Hope someone could point me in the right direction, threading is giving me grief:) Thank you.

  • Passing ByteArray from flash (as3) to AMFPHP (2.0.1)

    - by Mauro
    i have a problem passing ByteArray from flash (as3) to amfphp to save an image. With old version of amfphp, all worked in the past… now, with new version i have many problem. I'm using version 2.0.1 and the first problem is that i have to do this, for access to my info: function SaveAsJPEG($json) { $string = json_encode($json); $obj = json_decode($string); $compressed = $obj->{'compressed'}; } in the past i wrote only: function SaveAsJPEG($json) { $compressed = $json['compressed']; } Anyway… now i can take all data (if i use " $json['compressed']" i receive an error) but i can't receive my ByteArray data. From flash i write this: var tempObj:Object = new Object(); tempObj["jpgStream "]= createBitStream(myBitmmapData); // return ByteArray tempObj["compressed"] = false; tempObj["dir"] = linkToSave; tempObj["name"] = this.imageName; So.. in my php class i receive all correct info, except "jpgStream" that seems "null". Do you have any idea?

  • Rails select box in form decides on create action in controller?

    - by dannymcc
    Hi Everyone? I am trying to add a select box to the base of my create form that decides if an action runs from the controller...if that makes any sense? Basically the application creates a project in FreeagentCentral whenever a new project is made: def create @company = Company.find(params[:kase][:company_id]) @kase = @company.kases.create!(params[:kase]) respond_to do |format| params[:send_to_freeagent] ? @kase.create_freeagent_project(current_user) #flash[:notice] = 'Case was successfully created.' flash[:notice] = fading_flash_message("Case was successfully created.", 5) format.html { redirect_to(@kase) } format.xml { render :xml => @kase, :status => :created, :location => @kase } end end and within my form I have: <%= check_box_tag :send_to_freeagent, 1 % Create project in Freeagent? What I would like to happen, is if the select box is checked the project is sent to Freeagent. If not, the case just gets created locally as normal but without the Freeagent data being sent. If I use the above code, I get an exception caught error: SyntaxError in KasesController#new controllers/kases_controller.rb:114: syntax error, unexpected '\n' Any idea what I am doing wrong, also is it possible to make the check boxes checked as default? Thanks, Danny

  • What -W values in gcc correspond to which actual warnings?

    - by SebastianK
    Preamble: I know, disabling warnings is not a good idea. Anyway, I have a technical question about this. Using GCC 3.3.6, I get the following warning: choosing ... over ... because conversion sequence for the argument is better. Now, I want to disable this warning as described in gcc warning options by providing an argument like -Wno-theNameOfTheWarning But I don't know the name of the warning. How can I find out the name of the option that disables this warning? I am not able to fix the warning, because it occurs in a header of an external library that can not be changed. It is in boost serialization (rx(s, count)): template<class Archive, class Container, class InputFunction, class R> inline void load_collection(Archive & ar, Container &s) { s.clear(); // retrieve number of elements collection_size_type count; unsigned int item_version; ar >> BOOST_SERIALIZATION_NVP(count); if(3 < ar.get_library_version()) ar >> BOOST_SERIALIZATION_NVP(item_version); else item_version = 0; R rx; rx(s, count); std::size_t c = count; InputFunction ifunc; while(c-- > 0){ ifunc(ar, s, item_version); } } I have already tried #pragma GCC system_header but this had no effect. Using -isystem instead of -I also does not work. The general question remains is: I know the text of the warning message. But I do not know the correlation to the gcc warning options.

  • How do I display java.lang.* object allocations in Eclipse profiler?

    - by Martin Wickman
    I am profiling an application using the Eclipse profiler. I am particularly interested in number of allocated object instances of classes from java.lang (for instance java.lang.String or java.util.HashMap). I also want to know stuff like number of calls to String.equals() etc. I use the "Object Allocations" tab and I shows all classes in my application and a count. It also shows all int[], byte[], long[] etc, but there is no mention of any standard java classes. For instance, this silly code: public static void main(String[] args) { Object obj[] = new Object[1000]; for (int i = 0; i < 1000; i++) { obj[i] = new StringBuffer("foo" + i); } System.out.println (obj[30]); } Shows up in the Object Allocations tab as 7 byte[]s, 4 char[]s and 2 int[]s. It doesn't matter if I use 1000 or 1 iterations. It seems the profiler simply ignores everything that is in any of the java.* packages. The same applies to Execution Statistics as well. Any idea how to display instances of java.* in the Eclipse Profiler?

  • Block facebook from my website

    - by Joseph Szymborski
    I have a secure link direction service I'm running (expiringlinks.co). If I change the headers in php to redirect my visitors, then facebook is able to show a preview of the website I'm redirecting to when users send links to one another via facebook. I wish to avoid this. Right now, I'm using an AJAX call to get the URL and javascript to redirect, but it's causing problems for users who don't use javascript. Here are a number of ways I'd like to block facebook, but I can't seem to get working: I've tried blocking the facebook bot (facebookexternalhit/1.0 and facebookexternalhit/1.1) but it's not working, I don't think they're using them for this functionality. I'm thinking of blocking the facebook IP addresses, but I can't find all of them, and I don't think it'll work unless I get all of them. I've thought of using a CAPTCHA or even a button, but I can't bring myself to do that to my visitors. Not to mention I don't think anyone would use the site. I've searched the facebook docs for meta tags that would "opt-me out", but haven't found one, and doubt that I would trust it if I had. Any creative ideas or any idea how to implement the ones above? Thank you so much in advance!

  • Extracting noun+noun or (adj|noun)+noun from Text

    - by ssuhan
    I would like to query if it is possible to extract noun+noun or (adj|noun)+noun in R package openNLP?That is, I would like to use linguistic filtering to extract candidate noun phrases. Could you direct me how to do? Many thanks. Thanks for the responses. here is the code: library("openNLP") acq <- "Gulf Applied Technologies Inc said it sold its subsidiaries engaged in pipeline and terminal operations for 12.2 mln dlrs. The company said the sale is subject to certain post closing adjustments, which it did not explain. Reuter." acqTag <- tagPOS(acq) acqTagSplit = strsplit(acqTag," ") acqTagSplit qq = 0 tag = 0 for (i in 1:length(acqTagSplit[[1]])){ qq[i] <-strsplit(acqTagSplit[[1]][i],'/') tag[i] = qq[i][[1]][2] } index = 0 k = 0 for (i in 1:(length(acqTagSplit[[1]])-1)) { if ((tag[i] == "NN" && tag[i+1] == "NN") | (tag[i] == "NNS" && tag[i+1] == "NNS") | (tag[i] == "NNS" && tag[i+1] == "NN") | (tag[i] == "NN" && tag[i+1] == "NNS") | (tag[i] == "JJ" && tag[i+1] == "NN") | (tag[i] == "JJ" && tag[i+1] == "NNS")){ k = k +1 index[k] = i } } index Reader can refer index on acqTagSplit to do noun+noun or (adj|noun)+noun extractation. (The code is not optimum but work. If you have any idea, please let me know.) Furthermore, I still have a problem. Justeson and Katz (1995) proposed another linguistic filtering to extract candidate noun phrases: ((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun I cannot well understand its meaning, could someone do me a favor to explain it or transform such representation into R language

  • Different standard streams per POSIX thread

    - by Roman Nikitchenko
    Is there any possibility to achieve different redirections for standard output like printf(3) for different POSIX thread? What about standard input? I have lot of code based on standard input/output and I only can separate this code into different POSIX thread, not process. Linux operation system, C standard library. I know I can refactor code to replace printf() to fprintf() and further in this style. But in this case I need to provide some kind of context which old code doesn't have. So doesn't anybody have better idea (look into code below)? #include <pthread.h> #include <stdio.h> void* different_thread(void*) { // Something to redirect standard output which doesn't affect main thread. // ... // printf() shall go to different stream. printf("subthread test\n"); return NULL; } int main() { pthread_t id; pthread_create(&id, NULL, different_thread, NULL); // In main thread things should be printed normally... printf("main thread test\n"); pthread_join(id, NULL); return 0; }

  • HTTP Negotiate windows vs. Unix server implementation using python-kerberos

    - by ondra
    I tried to implement a simple single-sign-on in my python web server. I have used the python-kerberos package which works nicely. I have tested it from my Linux box (authenticating against active directory) and it was without problem. However, when I tried to authenticate using Firefox from Windows machine (no special setup, just having the user logged into the domain + added my server into negotiate-auth.trusted-uris), it doesn't work. I have looked at what is sent and it doesn't even resemble the things the Linux machine sends. This Microsoft description of the process pretty much resembles the way my interaction from Linux works, but the Windows machine generally sends a very short string, which doesn't even resemble the things microsoft documentation states, and when base64 decoded, it is something like 12 zero bytes followed by 3 or 4 non-zero bytes (GSS functions then return that it doesn't support such scheme) Either there is something wrong with the client Firefox settings, or there is some protocol which I am supposed to follow for the Negotiate protocol, but which I cannot find any reference anywhere. Any ideas what's wrong? Do you have any idea what protocol I should by trying to find, as it doesn' look like SPNEGO, at least from MS documentation.

  • What would be the best way to install (distribute) dynamic libraries in Mac OSX using CMake/Cpack ?

    - by YuppieNetworking
    Hello all, I have a project whose artifacts are two dynamic libraries, let's say libX.dylib and libY.dylib (or .so for linux distributions). There are no executables. Now I would like to distribute these libraries. Since I already use CMake to compile it, I looked at CPack and successfully generated .tgz and .deb packages for Linux. However, for Mac OSX I have no idea and the CPack Wiki about its generators did not help me much. I managed to generate a PackageMaker package, but as clearly stated at this packagemaker howto, there is no uninstall option when using this util. I then read a bit about Bundles, but I feel lost specially since I have no executable. Question: What is the correct way to generate a package for Mac OSX using CPack? My ideal scenario would be either something that installs as easily as a bundle or as a deb file in debian/ubuntu. Thanks for your help Edit One more detail: the code to one of these libraries is not open, so I can't expect the users to do a cmake; make; make install That's why I want a .deb, .tar.gz, bundle or whatsoever.

  • Unable to use certain Fonts programatically in ASP.Net

    - by TooFat
    I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts. <div> <% string fontName = "Segoe Script"; //Change Font here System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); System.Drawing.Font fnt = new System.Drawing.Font(fontName, 20); System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); graph.DrawString("Help", fnt, brush, new System.Drawing.Point(10, 10)); bmp.Save(@"C:\Development\Path\image1.bmp"); this.Image1.ImageUrl = "http://mysite/Images/image1.bmp"; %> <asp:Label ID="Label1" runat="server" Text="Label" Font-Names="Segoe Script"> <%Response.Write("Help"); %></asp:Label> //Change font here <asp:Image ID="Image1" runat="server" /> </div> If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.

  • No Debug information of an iPhone app

    - by Markus Pilman
    Hi all, I wrote an iPhone app which uses a third party library. I crosscompiled this library successfully and everything works smoothly. But when I want to debug the application, it would make sense to also be able to debug the library. So I compiled also the external library with debuging information (usign the gcc option -ggdb). But when I want to debug it, I get the correct symbol names, but the positions are always wrong/extremly wierd (locale_facets.tcc:2505 or iostream:76). For example a stack trace could look like this: #0 0x000045e8 in zorba::serialization::SerializeBaseClass::SerializeBaseClass () at iostream:76 #1 0x0001d990 in zorba::RCObject::RCObject () at iostream:76 #2 0x00025187 in zorba::xqpStringStore::xqpStringStore () at iostream:76 #3 0x000719e4 in zorba::String::String () at locale_facets.tcc:2505 #4 0x00030513 in iphone::iLabelModule::getURI (this=0x533f710) at /Users/sausalito/eth/izorba/sandbox/ilabel.cpp:19 #5 0x00356766 in zorba::static_context::bind_external_module () at locale_facets.tcc:2505 #6 0x0006139d in zorba::StaticContextImpl::registerModule () at locale_facets.tcc:2505 #7 0x000333e5 in -[ZorbaCaller init] (self=0x53405c0, _cmd=0x95583398) at /Users/sausalito/eth/izorba/sandbox/ZorbaCaller.mm:61 #8 0x00033180 in +[ZorbaCaller instance] (self=0x11dc2bc, _cmd=0x93679591) at /Users/sausalito/eth/izorba/sandbox/ZorbaCaller.mm:37 #9 0x0003d998 in -[testOne execute:] (self=0x530d560, _cmd=0x9366b126, sender=0x5121da0) at /Users/sausalito/eth/izorba/sandbox/generator/testOne.mm:13 #10 0x01a21405 in -[UIApplication sendAction:to:from:forEvent:] () #11 0x01a84b4e in -[UIControl sendAction:to:forEvent:] () #12 0x01a86d6f in -[UIControl(Internal) _sendActionsForEvents:withEvent:] () #13 0x01a85abb in -[UIControl touchesEnded:withEvent:] () #14 0x01a3addf in -[UIWindow _sendTouchesForEvent:] () #15 0x01a247c8 in -[UIApplication sendEvent:] () #16 0x01a2b061 in _UIApplicationHandleEvent () #17 0x03b6fd59 in PurpleEventCallback () #18 0x034a8b80 in CFRunLoopRunSpecific () #19 0x034a7c48 in CFRunLoopRunInMode () #20 0x03b6e615 in GSEventRunModal () #21 0x03b6e6da in GSEventRun () #22 0x01a2bfaf in UIApplicationMain () #23 0x0002dd7e in main (argc=1, argv=0xbffff044) at /Users/sausalito/eth/izorba/sandbox/main.m:16 Does anybody have an idea, where these wrong locations come from?

  • Permission denied to access property 'toString'

    - by Anders
    I'm trying to find a generic way of getting the name of Constructors. My goal is to create a Convention over configuration framework for KnockoutJS My idea is to iterate over all objects in the window and when I find the contructor i'm looking for then I can use the index to get the name of the contructor The code sofar (function() { constructors = {}; window.findConstructorName = function(instance) { var constructor = instance.constructor; var name = constructors[constructor]; if(name !== undefined) { return name; } var traversed = []; var nestedFind = function(root) { if(typeof root == "function" || traversed[root]) { return } traversed[root] = true; for(var index in root) { if(root[index] == constructor) { return index; } var found = nestedFind(root[index]); if(found !== undefined) { return found; } } } name = nestedFind(window); constructors[constructor] = name; return name; } })(); var MyApp = {}; MyApp.Foo = function() { }; var instance = new MyApp.Foo(); console.log(findConstructorName(instance)); The problem is that I get a Permission denied to access property 'toString' Exception, and i cant even try catch so see which object is causing the problem Fiddle http://jsfiddle.net/4ZwaV/

  • xml schema putting both sequence and all under one complexType node

    - by exiang
    Here is the xml file: <section> <number>1</number> <title>A Title goes here...</title> <code>TheCode</code> <element></element> <element></element> </section> In section node, there are number, title and code node. Their sequence must not be fixed. Then, there are multiple element under section node as well. The idea is to use the following schema: <xs:complexType name="Type-section"> <xs:all> <xs:element name="number" minOccurs="0"></xs:element> <xs:element name="code" minOccurs="1"></xs:element> <xs:element name="title" minOccurs="1"></xs:element> </xs:all> <xs:sequence> <xs:element maxOccurs="unbounded" name="element"></xs:element> </xs:sequence> </xs:complexType> But it is invalid. I just cant put "sequence" and "all" together in the same level. How can i fix it?

  • Regular Expression to replace a pattern at runtime(C#3.0)

    - by deepak.kumar.goyal
    I have a requirement. I have some files in a folder among which some file names looks like say **EUDataFiles20100503.txt, MigrateFiles20101006.txt.** Basically these are the files that I need to work upon. Now I have a config file where it is mentioned as the file pattern type as EUDataFilesYYYYMMDD, MigrateFilesYYYYMMDD. Basically the idea is that, the user can configure the file pattern and based on the pattern mentioned, I need to search for those files that are present in the folder. i.e. at runtime the YYYYMMDD will get replaced by the Year Month and Date Values. It does not matter what dates will be there(but not with time stamp ; only dates)). And the EUDataFiles or MigrateFiles names will be there.(they are fixed) i.e. If the folder has a file name as EUDataFile20100504.txt(i.e. Year 2010, Month 05, Day 04) , I should ignore this file as it is not EUDataFiles20100504.txt (kindly note that the name is plural - File(s) and not file for which the system will ignore the file). Similarly, if the Pattern given as EUDataFilesYYYYMMDD and if the file present is of type EUDataFilesYYYYDDMM then also the system should ignore. How can I solve this problem? Is it doable using regular expression(Replacing the pattern at runtime)? If so can anyone be good enough in helping me out? I am using C#3.0 and dotnet framework 3.5. Thanks
