• How to use iPhone SDK Private APIs

  - by eagle

  I haven't found a comprehensive list of the steps that are required to use a private API from the iPhone Library. In particular, I would like to know how to get header files, if they are even required, how to get it to compile (when I simply add the header, it complains that the functions aren't defined), and what resources one can use to learn about private APIs (e.g. from other user's experiences, such as http://iphonedevwiki.net/ which has a few). I've read in other places that people recommend using class-dump to get the headers. Are there any alternative methods? I've noticed that there are some repositories of iPhone Private SDKs, what are the most up to date resources you would recommend? Most of the previous questions about documentation of private APIs, have all linked to Erica Sadun's website, which doesn't seem to have documentation anymore (all the links on the left are crossed out). Please save the comments about not using private API's... I know of the biggest risks: App will get rejected by Apple. App will break in future updates to the OS. I'm talking about legitimate uses, such as: Private application use (e.g. for unit testing, or messing around to see what's possible)

• Search SharePoint ULS Logs with Windows

  - by djeeg

  Hi, I have a standard/new Windows 2008 R2 install with SharePoint 2010 and am looking for a SharePoint expectation that occurred sometime during the last week. So I open windows explorer, then go to the logs directory (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS). In the toolbar I can enter some search text (exception) or i can Ctrl-F which puts my cursor in the same search box. First it searches the filenames, comes back with no results, and then i click File Contents. And it comes back with still no results. Now I think, maybe there are no errors, so i search for something that I know is in the log (w3wp), still no results. In previous versions of windows, i could usually fix this by making *.log files read as text. But apparently (http://technet.microsoft.com/en-us/library/cc725753(WS.10).aspx) *.log files should already be read as text. Any idea how to make the search, really search log files. I would prefer a solution that did not involve installing any 3rd party software (eg like ULSViewer), but registry/powershell settings are okay.

• overriding enumeration base type using pragma or code change

  - by vprajan

  Problem: I am using a big C/C++ code base which works on gcc & visual studio compilers where enum base type is by default 32-bit(integer type). This code also has lots of inline + embedded assembly which treats enum as integer type and enum data is used as 32-bit flags in many cases. When compiled this code with realview ARM RVCT 2.2 compiler, we started getting many issues since realview compiler decides enum base type automatically based on the value an enum is set to. http://www.keil.com/support/man/docs/armccref/armccref_Babjddhe.htm For example, Consider the below enum, enum Scale { TimesOne, //0 TimesTwo, //1 TimesFour, //2 TimesEight, //3 }; This enum is used as a 32-bit flag. but compiler optimizes it to unsigned char type for this enum. Using --enum_is_int compiler option is not a good solution for our case, since it converts all the enum's to 32-bit which will break interaction with any external code compiled without --enum_is_int. This is warning i found in RVCT compilers & Library guide, The --enum_is_int option is not recommended for general use and is not required for ISO-compatible source. Code compiled with this option is not compliant with the ABI for the ARM Architecture (base standard) [BSABI], and incorrect use might result in a failure at runtime. This option is not supported by the C++ libraries. Question How to convert all enum's base type (by hand-coded changes) to use 32-bit without affecting value ordering? enum Scale { TimesOne=0x00000000, TimesTwo, // 0x00000001 TimesFour, // 0x00000002 TimesEight, //0x00000003 }; I tried the above change. But compiler optimizes this also for our bad luck. :( There is some syntax in .NET like enum Scale: int Is this a ISO C++ standard and ARM compiler lacks it? There is no #pragma to control this enum in ARM RVCT 2.2 compiler. Is there any hidden pragma available ?

• Cocos2D Director Pause/Resume Issue

  - by Aditya

  I am trying to play a .gif animation in cocos2D. For this i am using the library glgif. Now, to display the animation i am pausing the Director, adding a subview to show the animation and after the animation is done i am resuming the Director. However, I am not able to resume the state of the Director and it shows blank. So I tried this without pausing and resuming this Director and it still did not work.I also tried detaching the director before tha animation and adding it back afterwards and even that did not work. So is there a way to pause/suspend the Director in the application and properly restore is back? Thanks. Code sample: [[Director sharedDirector] pause]; [[Director sharedDirector] detach]; AppDelegate *del = [[UIApplication sharedApplication] delegate]; [del.window addSubview:del.viewController.view]; [del.window makeKeyAndVisible]; // this is code to call glgif class and start anim. //code to resume the director AppDelegate *del = [[UIApplication sharedApplication] delegate]; [[Director sharedDirector] resume]; [[Director sharedDirector] attachInView:del.window]; MScene *m = [MScene node]; [[Director sharedDirector] replaceScene:m];

• Mixing NIO with IO

  - by Steffen Heil

  Hi Usually you have a single bound tcp port and several connections on these. At least there are usually more connections as bound ports. My case is different: I want to bind a lot of ports and usually have no (or at least very few) connections. So I want to use NIO to accept the incoming connections. However, I need to pass the accepted connections to the existing jsch ssh library. That requires IO sockets instead of NIO sockets, it spawns one (or two) thread(s) per connection. But that's fine for me. Now, I thought that the following lines would deliver the very same result: Socket a = serverSocketChannel.accept().socket(); Socket b = serverSocketChannel.socket().accep(); SocketChannel channel = serverSocketChannel.accpet(); channel.configureBlocking( true ); Socket c = channel.socket(); Socket d = serverSocket.accept(); However the getInputStream() and getOutputStream() functions of the returned sockets seem to work different. Only if the socket was accepted using the last call, jsch can work with it. In the first three cases, it fails (and I am sorry: I don't know why). So is there a way to convert such a socket? Regards, Steffen

• Passing a NSArray between classes

  - by Althane

  So, my second question based off of this application I'm teaching myself Objective C with. I have a Data Source class, which for now looks mostly like: - (id) init { if (self = [super init]){ listNames = [[NSArray alloc] initWithObjects: @"Grocery", @"Wedding", @"History class",@"CS Class",@"Robotics",@"Nuclear Sciences", @"Video",@"Library",@"Funeral", nil]; NSLog(@"%@",listNames); } return self; } The .h looks as follows: @interface MainViewDataSource : NSObject { NSArray *listNames; } @property (nonatomic, retain) NSArray *listNames; -(NSArray *)getListNames; So that's where I make it. Now the problem is that when I try to get the array listNames, it returns nothing. The following piece: NSArray* data = [listData listNames]; Is supposed to put the information in listNames in data, but... isn't. Since I'm rather used to JAva, I'm betting this is an Objective C quirk that I don't know how to fix. Which is why I'd be here asking for help. What's the proper way to pass around NSArrays like this?

• BreezingForms Integrator Finalize Code and $this->execPieceByName('ff_InitLib');

  - by nickyt

  I've started working on a Joomla! project (I'm mainly a C#/ASP.NET kind a guy). I'm using BreezingForms and have created forms, got them working, but now I need to do some additional code in the "Finalize Code" section. I need to access form elements via BreezingForms(FacileForms) API. Here's what I'm doing, but it chokes: $this->execPieceByName('ff_SubmitLib'); // Is this necessary? // load the standard Facile Forms library $this->execPieceByName('ff_InitLib'); // page breaks here. // get the name of the uploaded file $filename = ff_getSubmit('someUploadedFile'); Now I don't know what goes wrong. The page posts back blank. I'm not sure how to debug this in Joomla. I currently do not have access to the server to debug, so I would need to debug remotely at runtime (not ideal I know). My account is of type Administrator for the Joomla backend. As far as I know all the plugins/modules are installed. Any ideas?

• Get more debug info from AxHost?

  - by Presidenten

  Hello I'm trying to deploy an application which uses an library that embeds an ActiveX control with AxHost in C#. When I run the installed app on our test rig I catch and present the following exception: Unexpected exception. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

I googled 0x800736B1, so I know that it means that a file could not be loaded. The big Q right now is how to find out which file it is that cant be loaded. Is there some sort of logging function I can turn on, or is there maybe som way I can get more info from the exception?

• tic tac toe in pascal --> a problem occurred

• Character encoding issues when generating MD5 hash cross-platform

  - by rogueprocess

  This is a general question about character encoding when using MD5 libraries in various languages. My concern is: suppose I generate an MD5 hash using a native Python string object, like this: message = "hello world" m = md5() m.update(message) Then I take a hex version of that MD5 hash using: m.hexdigest() and send the message & MD5 hash via a network, let's say, a JMS message or a HTTP request. Now I get this message in a Java program in the form of a native Java string, along with the checksum. Then I generate an MD5 hash using Java, like this (using the Commons Codec library): String md5 = org.apache.commons.codec.digest.DigestUtils.DigestUtils.md5Hex(s) My feeling is that this is wrong because I have not specified character encodng at either end. So the original hash will be based on the bytes of the Python version of the string; the Java one will be based on the bytes of the Java version of the string , these two byte sequences will often not be the same - is that right? So really I need to specify "UTF-8" or whatever at both ends right? (I am actually getting an intermittent error in my code where the MD5 checksum fails, and I suspect this is the reason - but because it's intermittent, it's difficult to say if changing this fixes it or not. ) Thank you!

• Mercurial Remote Subrepos

  - by Travis G

  I'm trying to set up my Mercurial repository system to work with multiple subrepos. I've basically followed these instructions to set up the client repo with Mercurial client v1.5 and I'm using HgWebDir to host my multiple projects. I have an HgWebDir with the following structure: http://myserver/hg fooproj mylib where mylib is some collection of common template library to be consumed by fooproj. The structure of fooproj looks like this: fooproj doc/ src/ .hgignore .hgsub .hgsubstate And .hgsub looks like: src/mylib = http://myserver/hg/mylib This should work, per my interpretation of the documentation: The first 'nested' is the path in our working dir, and the second is a URL or path to pull from. So, let's say I pull down fooproj to my home folder with: ~$ hg clone http://myserver/hg/fooproj foo Which pulls down the directory structure properly and adds the folder ~/foo/src/mylib which is a local Mercurial repository. This is where the problems begin: the mylib folder is empty aside from the items in .hg. With 2 seconds of investigation, one can see the src/mylib/.hg/hgrc is: [paths] default = http://myserver/hg/fooproj/src/mylib which is completely wrong (attempting a pull of that repo will give a 404 because, well, that URL doesn't make any sense). Logically, the default value should be what I specified in .hgsub or it would get the files from the repository in some way. None of the Mercurial commands return error codes (aside from a pull from within src/mylib), so it clearly believes that it is behaving properly (and just might be), although this does not seem logical at all. What am I doing wrong?

• Is there a workaround for JDBC w/liquibase and MySQL session variables & client side SQL instructions

  - by David

  Slowly building a starter changeSet xml file for one of three of my employer's primary schema's. The only show stopper has been incorporating the sizable library of MySQL stored procedures to be managed by liquibase. One sproc has been somewhat of a pain to deal with: The first few statements go like use TargetSchema; select "-- explanatory inline comment thats actually useful --" into vDummy; set @@session.sql_mode='TRADITIONAL' ; drop procedure if exists adm_delete_stats ; delimiter $$ create procedure adm_delete_stats( ...rest of sproc I cut out the use statement as its counter-productive, but real issue is the set @@session.sql_mode statement which causes an exception like liquibase.exception.MigrationFailedException: Migration failed for change set ./foobarSchema/sprocs/adm_delete_stats.xml::1293560556-151::dward_autogen dward: Reason: liquibase.exception.DatabaseException: Error executing SQL ... And then the delimiter statement is another stumbling block. Doing do dilligence research I found this rejected MySQL bug report here and this MySQL forum thread that goes a little bit more in depth to the problem here. Is there anyway I can use the sproc scripts that currently exist with Liquibase or would I have to re-write several hundred stored procedures? I've tried createProcedure, sqlFile, and sql liquibase tags without much luck as I think the core issue is that set, delimiter, and similar SQL commands are meant to be interpreted and acted upon by the client side interpreter before being delivered to the server.

• Visual Studio project using the Quality Center API remains in memory

  - by Traveling Tech Guy

  Hi, Currently developing a connector DLL to HP's Quality Center. I'm using their (insert expelative) COM API to connect to the server. An Interop wrapper gets created automatically by VStudio. My solution has 2 projects: the DLL and a tester application - essentially a form with buttons that call functions in the DLL. Everything works well - I can create defects, update them and delete them. When I close the main form, the application stops nicely. But when I call a function that returns a list of all available projects (to fill a combo box), if I close the main form, VStudio still shows the solution as running and I have to stop it. I've managed to pinpoint a single function in my code that when I call, the solution remains "hung" and if I don't, it closes well. It's a call to a property in the TDC object get_VisibleProjects that returns a List (not the .Net one, but a type in the COM library) - I just iterate over it and return a proper list (that I later use to fill the combo box): public List<string> GetAvailableProjects() { List<string> projects = new List<string>(); foreach (string project in this.tdc.get_VisibleProjects(qcDomain)) { projects.Add(project); } return projects; } My assumption is that something gets retained in memory. If I run the EXE outside of VStudio it closes - but who knows what gets left behind in memory? My question is - how do I get rid of whatever calling this property returns? Shouldn't the GC handle this? Do I need to delve into pointers? Things I've tried: getting the list into a variable and setting it to null at the end of the function Adding a destructor to the class and nulling the tdc object Stepping through the tester function application all the way out, whne the form closes and the Main function ends - it closes, but VStudio still shows I'm running. Thanks for your assistance!

• Activesupport::JSON.decode crashes on this,

  I wonder why i cant decode this json string, all what i want is to convert this to a proper Ruby hash, anyone have an idea? i think the array of objects is cracking it ?

• Executing MSYS from cmd.exe with arguments

  - by Chris Allison

  Hi, I am trying to learn wxWidgets library, using mingw and msys to compile the code. So far so good, but I can not find a way to send a command to MSYS through CMD.exe. I use SublimeText to edit files, and it has an option to run makefiles. I want my makefiles to be able to open an instance of MSYS and send the g++ command and arguments to it. Example: Right now my makefile is: test.exe : main.cpp g++ -s main.cpp -o test.exe `wx-config --cxxflags` `wx-config --libs` When mingw32-make goes to run the g++ command, it sends it to cmd.exe, which doesn't handle the back-ticks and wx-config jazz. (But the command does work when run from inside MSYS and the directory holding main.cpp) I want to be able to use something like... msys --command g++ -s main.cpp*...etc..* so it will load the msys enviroment, and run the command. Is this possible? I am a huge makefile newbie, so if there is an easier way, please show me! TIA!

• Highlighting a Table Correctly Despite rowspan and colspan attributes - WITHOUT jQuery

  - by ScottSEA

  Thanks to some !#$#@ in another department who wrote some crap code, I am unable to use the jQuery library - despite my fervent desire to do so. Their software has already been released into the world, and I have to be compatible. ============================================ I am trying to highlight a table. Desired behavior: Clicking on a cell in the body highlights the row. Clicking on a cell in the head highlights the column. If a column and row are both highlighted, the intersection is highlighted a different color (super-highlight). Clicking on a previously super-highlighted cell turns off the highlights. This behavior is simple enough to do with a basic table, but when rowspans and colspans start rearing their ugly heads, things start to get a little wonky... highlighting cell[5], for instance, no longer works reliably. My thought, in order to speed execution time of the highlighting itself (by changing a class name), is to pre-calculate the 'offsets' of all cells - with a 'colStart' and 'colEnd', 'rowStart' and 'rowEnd' when the page loads and store that in an array somehow. The question: How would YOU implement this functionality? I am fairly rusty at my JavaScript, awfully rudimentary in my programming skills and would benefit greatly from some guidance. Thanks, Scott.

• Creating A Single Generic Handler For Agatha?

  - by David

  I'm using the Agatha request/response library (and StructureMap, as utilized by Agatha 1.0.5.0) for a service layer that I'm prototyping, and one thing I've noticed is the large number of handlers that need to be created. It generally makes sense that any request/response type pair would need their own handler. However, as this scales to a large enterprise environment that's going to be A LOT of handlers. What I've started doing is dividing up the enterprise domain into logical processor classes (dozens of processors instead of many hundreds or possibly eventually thousands handlers). The convention is that each request/response type (all of which inherit from a domain base request/response pair, which inherit from Agatha's) gets exactly one function in a processor somewhere. The generic handler (which inherits from Agatha's RequestHandler) then uses reflection in the Handle method to find the method for the given TREQUEST/TRESPONSE and invoke it. If it can't find one or if it finds more than one, it returns a TRESPONSE containing an error message (messages are standardized in the domain's base response class). The goal here is to allow developers across the enterprise to just concern themselves with writing their request/response types and processor functions in the domain and not have to spend additional overhead creating handler classes which would all do exactly the same thing (pass control to a processor function). However, it seems that I still need to have defined a handler class (albeit empty, since the base handler takes care of everything) for each request/response type pair. Otherwise, the following exception is thrown when dispatching a request to the service: StructureMap Exception Code: 202 No Default Instance defined for PluginFamily Agatha.ServiceLayer.IRequestHandler`1[[TSFG.Domain.DTO.Actions.HelloWorldRequest, TSFG.Domain.DTO, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], Agatha.ServiceLayer, Version=1.0.5.0, Culture=neutral, PublicKeyToken=6f21cf452a4ffa13 Is there a way that I'm not seeing to tell StructureMap and/or Agatha to always use the base handler class for all request/response type pairs? Or maybe to use Reflection.Emit to generate empty handlers in memory at application start just to satisfy the requirement? I'm not 100% familiar with these libraries and am learning as I go along, but so far my attempts at both those possible approaches have been unsuccessful. Can anybody offer some advice on solving this, or perhaps offer another approach entirely?

• Packaging a qt application compiled with shared libraries

  - by Surjya Narayana Padhi

  Hi Geeks, I downloaded the qt embedded demo source code recently on my linux machine. Following are the outcomes during running of the program I compiled it statically on my x86 machine and run the application on x86 machine it runs fine. But when i took the statically compiled binary file to other machine with Atom platform It run with some missing widgets. I found that the plugins cant be ported with static compilation. Can anybody tell me is it true? If no can anybody tell me the steps for it? I compiled it dynamically with shared libraries. Then got an executalbe on linux. I did "ldd MyAppName". It show me the shared library files it is using. But I dont know how to package these. Can anybody tell me the steps to package it? I checked in the article on deploying qt applications on X11-linux platforms. But its not complete. Can anybody give me the detailed steps? Any help will be appreciated......

• Reading a WAV file into VST.Net to process with a plugin

  - by Paul

  Hello, I'm trying to use the VST.Net and NAudio frameworks to build an application that processes audio using a VST plugin. Ideally, the application should load a wav or mp3 file, process it with the VST, and then write a new file. I have done some poking around with the VST.Net library and was able to compile and run the samples (specifically the VST Host one). What I have not figured out is how to load an audio file into the program and have it write a new file back out. I'd like to be able to configure the properties for the VST plugin via C#, and be able to process the audio with 2 or more consecutive VSTs. Using NAudio, I was able to create this simple script to copy an audio file. Now I just need to get the output from the WaveFileReader into the VST.Net framework somehow. private void processAudio() { reader = new WaveFileReader("c:/bass.wav"); writer = new WaveFileWriter("c:/bass-copy.wav", reader.WaveFormat); int read; while ((read = reader.Read(buffer, 0, buffer.Length)) > 0) { writer.WriteData(buffer, 0, read); } textBox1.Text = "done"; reader.Close(); reader.Dispose(); writer.Close(); writer.Dispose(); } Please help!! Thanks References: http://vstnet.codeplex.com (VST.Net) http://naudio.codeplex.com (NAudio)

• Is this a bug? : I get " The type ... is not a complex type or an entity type" in my WCF data servic

  - by veertien

  When invoking a query on the data service I get this error message inside the XML feed: <m:error> <m:code></m:code> <m:message xml:lang="nl-NL">Internal Server Error. The type 'MyType' is not a complex type or an entity type.</m:message> </m:error> When I use the example described here in the article "How to: Create a Data Service Using the Reflection Provider (WCF Data Services)" http://msdn.microsoft.com/en-us/library/dd728281(v=VS.100).aspx it works as expected. I have created the service in a .NET 4.0 web project. My data context class returns a query object that is derived from the LINQExtender (http://linqextender.codeplex.com/). When I execute the query object in a unit test, it works as expected. My entity type is defined as: [DataServiceKey("Id")] public class Accommodation { [UniqueIdentifier] [OriginalFieldName("EntityId")] public string Id { get; set; } [OriginalFieldName("AccoName")] public string Name { get; set; } } (the UniqueIdentifier and OriginalFieldName attributes are used by LINQExtender) Does anybody know if this is a bug in WCF data services or am I doing something wrong?

• Navigating between pages in a Facebook Platform iframe application

  - by Jimmy Cuadra

  I'm working on a Facebook Platform application that runs in iframe mode, and I'm having trouble understanding how to navigate between pages within the app. Let's say the first page that is loaded within the iframe at my canvas URL is one.html. Within that page, there is a link to two.html that just changes the source of the iframe and doesn't reload the Facebook chrome. When I do this, all the Facebook fb_sig_* query string parameters that Facebook passes to the original page aren't included, and so two.html has no awareness of the connection to Facebook and no ability to make API calls to generate the content for the page. One possible solution would be to manually extract all the Facebook parameters from one.html and append it to the link to two.html myself. This seems really ugly and I figured there had to be a cleaner way. For reference, my application is written in Perl and uses the WWW::Facebook::API module as a client library. I didn't see anything in it that I can use to easily reconstruct the Facebook parameters for use with links in iframe apps. Another possible solution would be to store all the Facebook parameters in a session on my server on the first page load, and just use the values in that session on subsequent page views. But what happens if the data I've stored no longer matches what Facebook would have sent if it were a completely new request (i.e. something in the user's Facebook session changed)? Is there something obvious I'm missing? What is the standard approach to navigating between pages within an iframe app? Facebook's documentation is atrocious and I haven't been able to find anything that clearly explains how this works. I also realize this wouldn't be an issue with an app using FBML instead of an iframe, but my understanding is that iframe apps are now encouraged over FBML apps, though again this seems ambiguous since so much of Facebook's documentation is outdated and contradictory.

• Jquery html grab + calling a controller action using javascript (ruby on rails)

  - by Zind

  Preface: I consider myself "slightly effective" in ruby on rails, and a complete novice in javascript. Also, yes, I have installed jQuery and associated plugins instead of the default Prototype library. I am in a situation where I am pulling in a table from off-site in an iframe (which is taking care of all internal JS for me) such that when a part of the table is clicked, a td will gain the class "active." What I would like to do is take this info (I'm assuming I can get it in a string format), and pass it to a method (in my controller, I'm assuming) which will parse the html, pull out the pertinent info, and then call a creation method in the same controller with the parsed info, the end result being a new item in that table. What I have so far is javascript which I believe is correct so far: <script type="text/javascript"> var ImportInfo = function() { var info = $('td.active').html(); // call controller action which parses the given string, //checks for existence in database, and adds new row if needed } $("#Import").click(ImportInfo); </script> and, of course, a button with id="ImportLocation." I have looked at this question: http://stackoverflow.com/questions/1334447/using-jquery-to-call-a-controller-action but am somewhat unsure as to how to call a controller action to pass the contents of the td as a string. Is this doable with the jQuery post method?

• Custom ASPNetMembership FailureInformation always null, OnValidatingPassword issue

  - by bigb

  As stated here http://msdn.microsoft.com/en-us/library/system.web.security.membershipprovider.onvalidatingpassword.aspx "When the ValidatingPassword event has completed, the properties of the ValidatePasswordEventArgs object supplied as the e parameter can be examined to determine whether the current action should be canceled and if a particular Exception, stored in the FailureInformation property, should be thrown." Here is some details/code which really shows why FailureInformation shouldn't be always null http://forums.asp.net/t/991002.aspx if any password security conditions not matched. According with my Membership settings i should get an exception that password does not match password security conditions, but it is not happened. Then i did try to debug System.Web.ApplicationServices.dll(in .NET 4.0 System.Web.Security located here) Framework Code to see whats really happens there, but i cant step into this assembly, may be because of this [TypeForwardedFrom("System.Web, Version=2.0.0.0, Culture=Neutral, PublicKeyToken=b03f5f7f11d50a3a")] public abstract class MembershipProvider : ProviderBase Easily i may step into any another .NET 4.0 assembly, but in this one not. I did check, symbols for System.Web.ApplicationServices.dll loaded. Now i have only one idea how ti fix it - to override method OnValidatingPassword(ValidatePasswordEventArgs e). Thats my story. May be some one may help: 1) Any ideas why OnValidatingPassword not working? 2) Any ideas how to step into it?
