• Universal Authentication to Google Data API?

  - by viatropos

  Hey, I want to be able to have say 10 admin users store all their documents on google docs for a domain ('http://docs.google.com/a/domain.com'), and have everyone else be able to view them through 'domain.com/documents'. I'm just not certain how the whole authentication thing works in that case. Should I use OAuth? Or could I just use ClientLogin for say the root/global admin, and anytime someone goes to the site, they login as that? That works for personal docs, but it doesn't seem to be working for Google Apps. I would like it so the user has no idea they're accessing google docs, so I don't want them to have to say "Yes, Authenticate this App with Google", as seen in this Doclist Manager App. The app is basically: Admin stores a bunch of forms and documents User uses form and views documents the admin has posted ... so there's no need to access the user's Google Docs. But it seems like AuthSub and OAuth are addressing that instead... Thanks for the tips.

• What am I missing with log4net - No log file created

  - by Saif Khan

  I am trying to use log4net in a VB.NET app for some unknown reason it's not creating the log file. Here is my app.config <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> </configSections> <log4net> <appender name="FileAppender" type="log4net.Appender.FileAppender"> <file value="c:\log-file.txt" /> <appendToFile value="true" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <root> <level value="ALL" /> <appender-ref ref="FileAppender" /> </root> </log4net> </configuration> Here is the app code Imports log4net Public Class Form1 Dim log As ILog Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click log.Error("test") End Sub Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load log4net.Config.XmlConfigurator.Configure() log = log4net.LogManager.GetLogger("TestThings") End Sub End Class "TestThings" is the name of the VS project.

• Photo gallery not open in titanium 1.0

  - by user291247

  Hello, I am developing new app. using titanium 1.0 In that I am opening phtogallery in new window but I am not able to open it why this was happened?

• htaccess mod_rewrite check file/directory existence, else rewrite?

  - by devians

  I have a very heavy htaccess mod_rewrite file that runs my application. As we sometimes take over legacy websites, I sometimes need to support old urls to old files, where my application processes everything post htaccess. My ultimate goal is to have a 'Demilitarized Zone' for old file structures, and use mod rewrite to check for existence there before pushing to the application. This is pretty easy to do with files, by using: RewriteCond %{IS_SUBREQ} true RewriteRule .* - [L] RewriteCond %{ENV:REDIRECT_STATUS} 200 RewriteRule .* - [L] RewriteCond Public/DMZ/$1 -F [OR] RewriteRule ^(.*)$ Public/DMZ/$1 [QSA,L] This allows pseudo support for relative urls by not hardcoding my base path (I cant assume I will ever be deployed in document root) anywhere and using subrequests to check for file existence. Works fine if you know the file name, ie http://domain.com/path/to/app/legacyfolder/index.html However, my legacy urls are typically http://domain.com/path/to/app/legacyfolder/ Mod_Rewrite will allow me to check for this by using -d, but it needs the complete path to the directory, ie RewriteCond Public/DMZ/$1 -F [OR] RewriteCond /var/www/path/to/app/Public/DMZ/$1 -d RewriteRule ^(.*)$ Public/DMZ/$1 [QSA,L] I want to avoid the hardcoded base path. I can see one possible solutions here, somehow determining my path and attaching it to a variable [E=name:var] and using it in the condition. Another option is using -U, but the tricky part is stopping it from hijacking every other request when they should flow through, since -U is really easy to satisfy. Any implementation that allows me to existence check a directory is more than welcome. I am not interested in using RewriteBase, as that requires my htaccess to have a hardcoded base path.

• How important is managing memory in Objective-C?

  - by Alex Mcp

  Background: I'm (jumping on the bandwagon and) starting learning about iPhone/iPad development and Objective-C. I have a great background in web development and most of my programming is done in javascript (no libraries), Ruby, and PHP. Question: I'm learning about allocating and releasing memory in Objective-C, and I see it as quite a tricky task to layer on top of actually getting the farking thing to run. I'm trying to get a sense of applications that are out there and what will happen with a poorly memory-managed program. A) Are apps usually released with no memory leaks? Is this a feasible goal, or do people more realistically just excise the worst offenders and that's ok? B) If I make an NSString for a title of a view, let's say, and forget to deallocate it it, does this really only become a problem if I recreate that string repeatedly? I imagine what I'm doing is creating an overhead of the memory needed to store that string, so it's probably quite piddling (a few bytes?) However if I have a rapidly looping cycle in a game that 'leaks' an int every cycle or something, that would overflow the app quite quickly. Are these assumptions correct? Sorry if this isn't up the community-wiki alley, I'm just trying to get a handle on how to think about memory and how careful I'll need to be. Any anecdotes or App Store-submitted app experiences would be awesome to hear as well.

• Hiding keyboard in iPad with UITextView , can do this in iphone not iPad.

  - by user271753

  Hey the code below when written in HelloWorldAppDelegate.m in an iPhone app having UITextView hides the keyboard when the app starts : The UITextView is editable thats what I want in iPad Also But how can do the same in iPad its not working at all ! ! ! ! ! ! ! And also I have checked that I can use Subviews if I want to keep this to my app itself - (void)applicationDidFinishLaunching:(UIApplication *)application { //For hiding the Keyboard [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; [window addSubview:viewController.view]; [window makeKeyAndVisible]; } /// /// Hiding the Keyboard /// - (void)keyboardWillShow:(NSNotification *)note { //The UIWindow that contains the keyboard view UIWindow* tempWindow; //Because we cant get access to the UIKeyboard throught the SDK we will just use UIView. //UIKeyboard is a subclass of UIView anyways UIView* keyboard; //Check each window in our application for(int c = 0; c < [[[UIApplication sharedApplication] windows] count]; c ++) { //Get a reference of the current window tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:c]; //Get a reference of the current view for(int i = 0; i < [tempWindow.subviews count]; i++) { keyboard = [tempWindow.subviews objectAtIndex:i]; if (!strcmp(object_getClassName(keyboard), "UIKeyboard")) { NSLog(@"hide keyboard"); [keyboard setHidden:YES]; return; } } } } Regards

• Multiple database connection in Rails

• "Cannot open user default database" error with "User Instance=True"

  - by Keith

  I have a desktop application that uses Sql user instancing. This is my connection string: "Data Source=.\SqlExpress; AttachDbFilename=C:\path\file.mdf; Integrated Security=True; User Instance=True; Connect Timeout=100;" My application creates this DB, downloads a load of data into it from a web service and then does a lot of actions with it. The problem comes when I attempt to re-open the connection. I get a SqlException: "Cannot open user default database. Login failed. Login failed for user 'myDomain\myusername'." This error makes no sense in this context - I have no default database. I'm logging in to an instance created just for the current application, running separately from SqlExpress. There's no other way to connect to this DB. If I start the SqlExpress service and connect to the default instance it won't be visible. It only exists for this application. The file on disk is locked by the SqlExpress instance service running under the application. if I stop the app and restart it the connection works first time, but fails on re-opening. If I just stop the app I can delete the .mdf files and begin again, but it still crashes when I re-open the connection. As my app started the instance running as me my current user should have access to every DB in the instance. This doesn't happen for other users of the same code, which suggests that it's a SQL config issue. Does anyone have any idea what causes this and how to work around it?

• How do I best handle a needed patch for Perl/Tk?

  - by Streamline

  I am making a change to Perl/Tk for an application that has its own resident Perl and modules installation (so we can drop the app in and go).

• Google Contacts API - No Redirection

  - by mecablaze

  Hello there, I am currently working on Contact Importer web app (in PHP) so I will be able to grab email address from a user's account on Gmail, Yahoo, etc and use them for my own evil purposes. Just kidding, my web app is very friendly. I thought I would start with Google. I found they have a fantastic little API called Google Contacts API which lets a programmer, like myself, to access a user's contacts. After a couple of hours of struggling and throwing shitty code together, I ran into a few road-blocks. My main question is this: Is there any way that I can have a user provide their username and password for Gmail on my website and have my code retrieve the contacts without that nasty redirection to a Google login page? It's kind of ruins the whole flow of my web app. I've looked into AuthSub, and gotten that to work, but of course the catch is that you have to redirect the user to obtain the access token. It looks like OAuth will have this same catch. The one ray of hope I have is the ClientLogin method of authentication. Again, there is a catch, sometimes Google throws you a CAPTCHA instead of the auth token. Again, the user flow is ruined. I've noticed that our good ol' friends over at Twitter have it working just fine. Does anyone know how they do it? Thanks!

• iPhone - Failed to save the videos metadata to the filesystem.

  - by cameron

  My application uses the UIImagePicker to allow the user to use the camera and capture a photo to edit/etc. I am getting the error message below: 2010-02-03 10:41:24.018 LivingRoom[5333:5303] Failed to save the videos metadata to the filesystem. Maybe the information did not conform to a plist. Program received signal: “EXC_BAD_ACCESS”. A search in Google brings up a number of threads in various forums, with no ultimate response/root cause/suggestions on how to fix/debug. An example is the thread below with code which is very similar to my app: http://groups.google.com/group/iphonesdkdevelopment/browse_thread/thread/6b7b396c62bef398 The error disappears for a while (10 tests in a row, no errors) if I reboot the iPhone. I have not been able to determine what makes it reoccur after a reboot, but it does. I am not using the video source and the fact that a reboot solves the problem for a while points to some sort of mem leak (perhaps?). The problem always shows up on both the iPhone (even after the reboot) and the simulator when choosing a photo from the album, but the app does not crash on the iPhone or the simulator. The same app with exact code did not have the error message when compiled using SDK 3.0 (last August/September). But 3.1.x has always produced the error message, which means that once a week or so the iPhone needs to be rebooted for the error to disappear. The users are not happy with that solution any longer!! Any suggestion/clues would be greatly appreciated.

• Using iphone accelerometer AND UIEventSubtypeMotionShake event simultaneousluy.

  - by lukya

  Hi, I am using accelerometer to move/change things on the screen in my app. I also need to detect UIEventSubtypeMotionShake in the view controller for some other animations. As my app is a simple view based app, there is just one view controller which acts as UIAccelerometerDelegate AND FirstResponder (for detecting the shake event). After the first Shake gesture is detected, I don’t need accelerometer inputs through [accelerometer didAccelerate] method so I set the accelerometer delegate to nil. -(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event { if (motion == UIEventSubtypeMotionShake) { NSLog(@"shake"); [[UIAccelerometer sharedAccelerometer] setDelegate:nil]; //my shake handling code } } The problem is that the first shake motion is not being detected correctly. I have to shake 2 3 or more times to trigger the UIEventSubtypeMotionShake event, while the subsequent shakes, after the accelerometer delegate is made nil, are being detected perfectly. This must be happening because UIEventSubtypeMotionShake in turn depends on the accelerometer didAccelerate events which are being overridden by my code. But I need to use both the events. Are there any apps or code samples which use both accelerometer and UIEventSubtypeMotionShake simultaneously? Thanks Swapnil

• Doubts About Core Data NSManagedObject Deep Copy

  - by Jigzat

  Hello everyone, I have a situation where I must copy one NSManagedObject from the main context into an editing context. It sounds unnecessary to most people as I have seen in similar situations described in Stackoverflow but I looks like I need it. In my app there are many views in a tab bar and every view handles different information that is related to the other views. I think I need multiple MOCs since the user may jump from tab to tab and leave unsaved changes in some tab but maybe it saves data in some other tab/view so if that happens the changes in the rest of the views are saved without user consent and in the worst case scenario makes the app crash. For adding new information I got away by using an adding MOC and then merging changes in both MOCs but for editing is not that easy. I saw a similar situation here in Stackoverflow but the app crashes since my data model doesn't seem to use NSMutableSet for the relationships (I don't think I have a many-to-many relationship, just one-to-many) I think it can be modified so I can retrieve the relationships as if they were attributes for (NSString *attr in relationships) { [cloned setValue:[source valueForKey:attr] forKey:attr]; } but I don't know how to merge the changes of the cloned and original objects. I think I could just delete the object from the main context, then merge both contexts and save changes in the main context but I don't know if is the right way to do it. I'm also concerned about database integrity since I'm not sure that the inverse relationships will keep the same reference to the cloned object as if it were the original one. Can some one please enlighten me about this?

• Rails deployment strategies with Bundler and JRuby

  - by brad

  I have a jruby rails app and I've just started using bundler for gem dependency management. I'm interested in hearing peoples' opinions on deployment strategies. The docs say that bundle package will package your gems locally so you don't have to fetch them on the server (and I believe warbler does this by default), but I personally think (for us) this is not the way to go as our deployed code (in our case a WAR file) becomes much larger. My preference would be to mimic our MVN setup which fetches all dependencies directly on the server AFTER the code has been copied there. Here's what I'm thinking, all comments are appreciated: Step1: Build war file, copy to server Step2: Unpack war on server, fetch java dependencies with mvn Step3: use Bundler to fetch Gem deps (Where should these be placed??) * Step 3 is the step I'm a bit unclear on. Do I run bundle install with a particular target in mind?? Step4: Restart Tomcat Again my reasoning here is that I'd like to keep the dependencies separate from the code at deploy time. I'd also like to place all gem dependencies in the app itself so they are contained, rather than installing them in the app user's home directory (as, again, I believe is the default for Bundler)

• How to create a rails staging environment in engineyard?

  - by siulamvictor

  I have a production instance in engineyard up and running well. I would like to create a new staging instance for internal testing. I cloned the existing production instance, changed Framework Environment to staging. I can deploy all the code to staging instance from Github. Engineyard reported the server is fully configured and ready. I have subdomain-fu in my Rails app, as I have some subdomain handling in my app. I set the subdomain initializer like this.... SubdomainFu.tld_sizes = {:development => 1, :test => 0, :production => 1, :staging => 2} As the production instance is using the domain xxxxx.com, I would like my staging instance use the domain staging.xxxxx.com. But I got an error when open this domain. Seems the app use xxxxx.com as domain but not the staging.xxxxx.com. I checked the engineyard database.yml. It use xxxxx_production database, I supposed it should be xxxxx_staging. Seems the engineyard instance is not set to staging environment, but just clone all the setting from production server. Does anyone have experience with this and can show me the way on how to fix it? Thanks. :)

• WCF Double Hop questions about Security and Binding.

  - by Ken Maglio

  Background information: .Net Website which calls a service (aka external service) facade on an app server in the DMZ. This external service then calls the internal service which is on our internal app server. From there that internal service calls a stored procedure (Linq to SQL Classes), and passes the serialized data back though to the external service, and from there back to the website. We've done this so any communication goes through an external layer (our external app server) and allows interoperability; we access our data just like our clients consuming our services. We've gotten to the point in our development where we have completed the system and it all works, the double hop acts as it should. However now we are working on securing the entire process. We are looking at using TransportWithMessageCredentials. We want to have WS2007HttpBinding for the external for interoperability, but then netTCPBinding for the bridge through the firewall for security and speed. Questions: If we choose WS2007HttpBinding as the external services binding, and netTCPBinding for the internal service is this possible? I know WS-* supports this as does netTCP, however do they play nice when passing credential information like user/pass? If we go to Kerberos, will this impact anything? We may want to do impersonation in the future. If you can when you answer post any reference links about why you're answering the way you are, that would be very helpful to us. Thanks!

• JSON: Jackson stream parser - is it really worth it?

  - by synic

  I'm making pretty heavy use of JSON parsing in an app I'm writing. Most of what I have done is already implemented using Android's built in JSONObject library (is it json-lib?). JSONObject appears to create instances of absolutely everything in the JSON string... even if I don't end up using all of them. My app currently runs pretty well, even on a G1. My question is this: are the speed and memory benefits from using a stream parser like Jackson worth all the trouble? By trouble, I mean this: As far as I can tell, there are three downsides to using Jackson instead of the built in library: Dependency on an external library. This makes your .apk bigger in the end. Not a huge deal. Your app is more fragile. Since the parsing is not done automatically, it is more vulnerable to changes in the JSON text that it's parsing. I'm extremely worried that malformed JSON will result in infinite loops (as pull parsing requires a lot of while loops). Writing code to parse JSON via a stream parser is ugly and tedious.

• Missing chars in JpGraph

  - by Álvaro G. Vicario

  I have a web site that runs on Windows and uses cp1252 (aka Win-1252) so it can display Spanish characters. The app generates some plots with JpGraph 2.3. These plots use the Tahoma Open Type font family to display text labels. Strings are provided in ANSI (i.e., cp1252) and font files support cp1252 (actually, the *.ttf files were copied from the system's font folder). It's been working fine in several setups from PHP/5.2.6 to PHP/5.3.0. Problems started when I ran the app under PHP/5.3.1: all non-ASCII are replaced by the hollow rectangle that represents missing or unknown chars. JpGraph's documentation is not very precise about how it expects international chars. Apparently, text is handled internally by the imagettftext() function, which expects UTF-8. However, encoding everything as UTF-8 breaks the app in all the systems. Where ANSI used to work fine, I get wrong characters (Ê instead of Ú). Where I got missing chars, now I get a PHP error: Warning: imagettftext(): any2eucjp(): something happen Do you have any clue about what changed in GD2 from PHP/5.3.0 to 5.3.1 that could be affecting the rendering on non-ASCII chars? How am I expected to feed JpGraph with strings in the Win-1252 charset?

• Rails 3 memory issue

  - by Erik

  Hello! I'm developing a new site based on Ruby on Rails 3 beta. I knew this might be a bad idea considering it's just beta, but I still thought it might work. Now though I'm having HUGE problems with Rails consuming huge ammounts of memory. For my application today it consumes about 10 mb per request and it doesn't seem to release it either. So I thought this might be because of bloat in my application and thus I created a test app just to compare. For my test app I just generated a model with a scaffold and then created about 20 records on this model. I then went to the index page and hit refresh and I could immediately see memory taking off! Less than my app but still about 1-3 mb per request. I'm working in OSX Leopard, with Ruby 1.8.7, Rails 3.0.0.beta and a SQLLite db for development. Does anyone recognize my problem? I would really appreciate some help here. :/ Thanks!

• UIImagePickerController shows last picture taken instead of camera input

  - by jules

  I'm having a strange behaviour within my app. For taking pictures i'm using the following pretty standard code for displaying the UIImagePickerController: UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.allowsEditing = NO; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentViewController:picker animated:YES completion:nil]; It works perfectly fine the first time I tap the button which calls this action. The strange behaviour starts when I tap that button again. The UIImagePickerController starts again BUT it doesnt show the input from the camera anymore. It shows the last picture I've taken. More Details of this state: Tapping on the image shows the yellow square of the auto focus. (which it actually uses to focus the camera correctly) When I tap on the ImageCapture button - the correct image is taken and presented on the screen. If I take a picture and press 'Retake' the regular camera image is presented as input. More weirdness: It has nothing to do with the iPad I'm using. Creating a new example app which only has button which calls the code from above everything works perfectly fine. I assume it has something to do with the configuration of the app. Therefore I checked everything but could not find any differences which may cause this issue. Thanks in advance for any advice! Update: I do implement the UIImagePickerControllerDelegate in order to dismiss the UIImagePickerController.

• Subview Doesnt AutoSize When Added to Root View Controller

  - by Per

  Hello, I have a root view controller that will have up to 10 or so subviews. I am implementing autorotation/autosize accross the entire app. My problem is this: - When I allocate all the view controllers and add each as a subview to the root controller during startup, everything works as it should. The only problem is that each view controller needs time to initialize. This causes my application to load very slowly. Instead I am trying to allocate the view controllers as they are required. Now I find that if the application goes into Landscape, and I allocate a view controller that is designed in portrait, it will autorotate but the autosize doesnt happen. In other words as soon as the subview is added to the root controller in portrait mode it rotates and sizes correctly (and stays that way). If the subview is added when the root controller is in landscape it rotates but doesnt autosize (and view sizes remain messed up rotating back to portrait) I have tried to force an autosize by calling SetNeedsLayout, SetNeedsDisplay, and LayoutIfNeeded but nothing works. I know i could probably do this manually by determining the root controllers orientation and resizing the subviews appropriately, but this is a lot of work for something that should work automatically. Am I missing something? Any help would be appreciated. My project is an iPad port from an iPhone app, the iPhone app doesnt rotate so Im not sure if this may be something wrong with the 3.2 beta.

• WCF Service in Azure with ClaimsIdentity over SSL

  - by Sunil Ramu

  Hello , Created a WCF service as a WebRole using Azure and a client windows application which refers to this service. The Cloud Service is refered to a certificate which is created using the "Hands On Lab" given in windows identity foundation. The Web Service is hosted in IIS and it works perfect when executed. I've created a client windows app which refers to this web service. Since WIF Claims identity is used, I have a claimsAuthorizationManager Class, and also a Policy class with set of defilned policies. The Claims is set in the web.config file. When I execute the windows app as the start up project, the app prompts for authentication, and when the account credentials are given as in the config file, it opens a new "Windows Card Space" Window and Says "Incoming Policy Failed". When I close the window the System throws and Exception The incoming policy could not be validated. For more information, please see the event log. Event Log Details Incoming policy failed validation. No valid claim elements were found in the policy XML.

• Android Apps not working in emulator

  - by Mohit Deshpande

  None of my apps work in the emulator. I am running Ubuntu 9.10 and everytime I try to access my UI, the app crashes. All I get is an "Sorry! The application ... has stopped unexpectedly". For EVERY app this happens. package com.mohit.helloandroid; import android.app.TabActivity; import android.content.Intent; import android.content.res.Resources; import android.os.Bundle; import android.widget.TabHost; public class HelloAndroid extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); //Resource object to get drawables TabHost tabHost = getTabHost(); //The activity tabhost TabHost.TabSpec spec; //Reusable tab spec Intent intent; intent = new Intent().setClass(this, HelloAndroid.class); spec = tabHost.newTabSpec("artists").setIndicator("Artists", res .getDrawable(R.drawable.tab_artists)) .setContent(intent); tabHost.addTab(spec); } } I don't know how this code could possibly throw a message like that.

• What are the limitations of the .NET Assembly format?

  - by McKAMEY

  We just ran into an interesting issue that I've not experienced before. We have a large scale production ASP.NET 3.5 SP1 Web App Project in Visual Studio 2008 SP1 which gets compiled and deployed using a Website Deployment Project. Everything has worked fine for the last year, until after a check-in yesterday the app started critically failing with BadImageFormatException. The check-in in question doesn't change anything particularly special and the errors are coming from areas of the app not even changed. Using Reflector we inspected the offending methods to find that there were garbage strings in the code (which Reflector humorously interpreted as Chinese characters). We have consistently reproduced this on several machines so it does not appear to be hardware related. Further inspection showed that those garbage strings did not exist in the Assemblies used as inputs to aspnet_merge.exe during deployment. Web Deployment Project Output Assemblies Properties: Merge all outputs to a single assembly Merge each individual folder output to its own assembly Merge all pages and control outputs to a single assembly Create a separate assembly for each page and control output In the web deployment project properties if we set the merge options to the first option ("Merge all outputs to a single assembly") we experience the issue, yet all of the other options work perfectly! So my question: does anyone know why this is happening? Is there a size-limit to aspnet_merge.exe's capabilities (the resulting merged DLL is around 19.3 MB)? Are there any other known issues with merging the output of WAPs? I would love it if any Assembly format / aspnet_merge gurus know about any such limitations like this. Seems to me like a 25MB Assembly, while big, isn't outrageous. Less disk to hit if it is all pregen'd stuff.
