• BlackBerry - Multiple Screens or Single Screen with Content Manager?

  - by Max Gontar

  Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!

• On which Windows versions and configurations does my C++ app run?

  - by saas

  I've built a C++ application using MSVC 2010, default compile settings (note: Using "Multithreaded" instead of "Multithreaded DLL" to avoid the Microsoft C++ runtime being needed). I used only the STL and a few, old functions from the Win32 API (Windows.h). Where will my app run? (98-7?) Can the be any differences on how my app works on different PCs? As said: It's only a simple console app. I'd be glad if you could add some additional information if you have it!

• Are unspecified and undefined behavior required to be consistent between compiles?

  - by sharptooth

  Let's pretend my program contains a specific construct the C++ Standard states to be unspecified behavior. This basically means the implementation has to do something reasonable but is allowed not to document it. But is the implementation required to produce the same behavior every time it compiles a specific construct with unspecified behavior or is it allowed to produce different behavior in different compiles? What about undefined behavior? Let's pretend my program contains a construct that is UB according to the Standard. The implementation is allowed to exhibit any behavior. But can this behavior differ between compiles of the same program on the same compiler with same settings in the same environment? In other words, if I dereference a null pointer on line 78 in file X.cpp and the implementation formats the drive in such case does it mean that it will do the same after the program is recompiled?

• Notice Undefined index url

  - by user1906992

  I'm doing youtube mvc tutorial http://www.youtube.com/watch?v=Aw28-krO7ZM and have stopped on the best first step: my index.php file: <?php $url = $_GET['url']; require 'controllers/' . $url . '.php'; My .htaccess file: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^(.+)$ index.php?url=$1 [QSA,L] so, the question is next: when i go on any other url except 'index' it works good. So what's wrong with 'index' url? Notice: Undefined index: url in /var/www/sadman/index.php on line 2 Warning: require(controllers/.php) [function.require]: failed to open stream: No such file or directory in /var/www/sadman/index.php on line 4 Btw, i have LAMP, and i think my settings are wright.

• A way to search form table in MySQL database.

  - by Eugene

  I looked for a way to scan database for a specific table. For example i have: Database: system_ultimate Table: system_settings And let us say, that one doesn't know precise name of the table. He only knows, that it is some how connected to word settings. How could he search for that table name then? I understand, that usually people who develop know, what they develop, but I'm trying to get hang of MVC and I'm trying to stay as far away as possible from direct communication with table using the name. I know, that to see all tables I could use SHOW TABLES;

• How do I require a login for a user in Django?

  - by Di Zou

  In my urls.py I have this: (r'^myapp/$', 'myapp.views.views.index'), (r'^myapp/login/$', 'myapp.views.views.login_user'), In my settings.py I have this: LOGIN_URL = '/myapp/login' In my views.py I have this: @login_required((login_url='/myapp/login/') def index(request): return render_to_response('index.html') def login_user(request): #login stuff return render(request, 'registration/login.html', {'state':state, 'username': username}) I can go to mysite.com/myapp/login and the login page works. However, when I go to mysite.com/myapp/index I do not get redirected to the login page even though I am logged out. Why is that and how do I fix it?

• CSS Rule Priorities

  - by Antilogic

  Given the following mark-up... <div id="Header"> <a href="#" class="Highlight">foo</a> </div> And the following stylesheet... /******************Exceptions******************/ #Footer, #Header, #Footer a, #Header a { color: #f8f8f8; } /******************Classes******************/ .Highlight, a.Highlight { color: #B1D355; } .Notification, a.Notification { color: Red; } Why is my link still off-white (F8F8F8) rather than green (B1D355)? Shouldn't using the class Highlight override the color settings for Header and Footer since it comes after their declarations?

• ColdFusion debugging output in my Ajax

  - by cf_PhillipSenn

  If I turn off "Enable Request Debugging Output", the 3rd option under the Debug Output Settings, then I no longer get debug info in my $.ajax call to a cfc with access="remote". That's good, but I'd like to keep it turned on for all my other programs and turn it off programatically for this one exception. I put <cfsetting showdebugoutput="false"> at the top of my Index.cfm, but that didn't turn off the debug output coming from the cfc. Oh wait. Never mind. I had to put the in the function rather than in Index.cfm.

• Arrays and application data

  - by s0mmer

  Hello everyone, At the moment i'm making an application where it is possible to make profiles with different settings. Which datatypes would you recommend me saving these information in? I have a table which is showing the profile name and the version number. But for each profile there need to be stored more information. Therefore the idea i'm working on have 2 arrays. 1 for all the profile information and 1 who is being made when loading the information. The second array is the one going to be showed in the table. Because the table doesnt show all the stored information. .. but this seems kinda stupid. Is there a more suitable method for saving the information in like 1 array, and just pass part of the data to the tableview?

• Can I override a group policy setting as a machine admin?

  - by Max

  Group policy prevents several configuration settings on my Windows 7 / Vista machines. Since my domain account is a member of the local Administrators group on these boxes, is there still a way to override them locally? For instance, GP prevents changing the power management option "Turn off the display" (even changing it from cmd fails: POWERCFG -X -monitor-timeout-ac 60 = "An unexpected error condition has occurred. Unable to perform operation. You may not have permission to perform this operation.") Even when logging on with a local account and not the domain account, it's not possible to change the setting anymore ..

• wordpress not properly functioning anymore after moving it to another domain

  - by Andy

  Hi, I followed the instructions on http://codex.wordpress.org/Moving_WordPress under 'Moving WordPress to a New Server' and 'If You Want Your Old Blog To Still Work' So I made a copy of everything marked is as old, then changed the domain under the WP settings, made a new copy. And now put the first copy back but when I go to the login page I can reach it, but it's without the usual markup as first. It's all skinned out. After I login, worpress uses the new domain instead of the old domain which the old copy of wordpress used!! what went wrong?? thanks.

• Ways to Unit Test Oauth for different services in ruby?

  - by viatropos

  Are there any best practices in writing unit tests when 90% of the time I'm building the Oauth connecting class, I need to actually be logging into the remote service? I am building a rubygem that logs in to Twitter/Google/MySpace, etc., and the hardest part is making sure I have the settings right for that particular provider, and I would like to write tests for that. Is there a recommended way to do that? If I did mocks or stubs, I'd still have to spend that 90% of the time figuring out how to use the service, and would end up writing tests after the fact instead of before...

• require user to login in at login screen before giving access to iPhone app that accesses secure web

  - by MikeN

  On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.

• In Xcode, the main controller is hopelessly misconfigured. What are the steps I can take to fix all

  - by MikeN

  Somehow the main .xib file for my iphone project got deleted. I created a replacement .xib file, but the properties are not setup correctly for the MainWindow to load this one. I don't understand and am hopelessly confused about any of the properties and which ones may or may not be sent. What are the X properties that all need to be set to have this work correctly? I've checked all of these, but there appear to be others: 1) The app delegate for the project is set to the new ControllerUI class. 2) The MainWindow.xib shows the correct .xib file as being loaded from (it has a link in its UI to the .xib file that should be loaded on project run. There appear to be other settings that have to be changed and I can't find them. Is there a way in XCode to recreate the MainWindow.xib file? Should I just create a new project and move all of the other files into it?

• Eclipse C++ on WinXP - Type `::iterator' has not been declared

  - by redwolfe

  I'm new to C++/Eclipse. I'm trying to get it working to get a new perspective on a problem with a program I wrote in DevCPP. The program is simple and builds fine in DevCPP. In Eclipse, I get hundreds of errors like the one above. I assume the compiler can't see my include files. I've checked that the project settings - GCC C++ compiler - directories contains the location for my include files (D:\MinGW\include\c++\3.4.5). I've prowled around and tried to change 'Discovery Options' to 'GCC C++ Compiler' from 'GCC C Compiler' but it keeps changing back. I guess this is not the problem. Any help would be very welcome. I'm on a tight deadline with many interruptions and this is cracking me up.

• Utilizing a third party application for GitHub in a django project

  - by Smock

  I'm trying to use a third party application located here: git://github.com/Star2Billing/django-audiofield.git I'm using Aptana Studio as my IDE. I created my project and then I clicked on the project and imported the app from the github location. It looked like it imported. I wanted to check that it imported properly before beginning any real coding so I performed manage.py validate. I got a message that stated: "No module named audiofield". I added the app to my Installed Apps settings and followed the installation instructions. I'm not sure if I'm importing it incorrectly. Also, I'm using virtualenv in Aptana. I'm not sure if this may have added to the problem. Please help.

• How do I use a default setting from Root.plist?

  - by crooksy88

  I have set up a default setting for my app using Root.plist, giving this a Boolean DefaultValue of YES (ticked checkbox).You can see a screengrab at http://www.infin8design.com/clients/stack/plist.png However, when my app is first launched, the YES value is not picked up, and the setting is read as a NO (or 0). The user has to manually go into the settings app, turn the toggleswitch off, then turn it back on again for this setting to hold a YES(1) value. I'm logging the value with appDidFinishLaunching like this. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSLog(@"%d",[defaults boolForKey:@"include_phrases"]); SO... my question is... How do I pick up this initial default setting without the user having to set it manually? Thanks in advance for any suggestions you can offer. Mark

• Which icons/buttons to use for help, about, info?

  - by 4thSpace

  I use the info button to display a settings page. This page is a modal. I need another button from here to display "About" info, since I've already used "info" for something. I have a search form that is accessed only from the modal. On the search form, I need a help icon. I can use the info button but that seems confusing, since I already use the info button from the main view to access the modal. What else can I do for help and about icons/buttons?

• XCode Project Code Changes Not Updating 100% After Save-Build-Run

  - by Greg

  When I make code changes to my iPhone game project in XCode, and then do CMD-B + Enter, I expect the project to be saved, build and run on the simulator with the latest. What is happening though, sometimes, is that it doesn't pick up a small change I make unless I clean the project and then build. I'm a long time Java person and newish to C-based languages and it's compiler. Can someone explain to me what is cached after each build that does this and how to change my project settings to avoid having to clean everytime? Or tell me the bad news that this is part of C development? Not trying to bash it - I get compiled JSPs stuck in the working cache often in Java, too. :P

• My table cells don't highlight immediately when touched

  - by Steve Denenberg

  Hi, In my app, I have a table view that has about eight cells. There is a navigation bar at the top. When a user touches a cell, nothing happens for about 1/2 second. Then the touched cell highlights blue and immediately the new view slides into position. The problem is that there is no feedback to the user about which cell he touched until just before the new view slides into position. For example, when I explore the tables in the iPhone's Settings application, when you touch a cell, the cell immediately turns blue, and then there is a 1/2 second delay, and then you see the new view. How do I get my table's feedback of highlighting the cells to happen immediately? I am using tableView didSelectRowAtIndexPath:, and each cell has an accessory button. Thanks for any insight.

• Django development server serving css but not js

  - by Wisco crew

  I am developing a django (1.4) app on my local machine. I am running the built-in development server with python manage.py runserver. In base.html I have: <link href="{{ STATIC_URL }}bootstrap.css" rel="stylesheet" type="text/css" /> <script src="{{ STATIC_URL }}boostrap-dropdown.js" type="text/javascript"></script> boostrap.css loads just fine when I load a page, but bootstrap-dropdown.js is 404'd. They are sitting right next to each other in my static directory. Relevant parts of settings.py: STATIC_URL = '/static/' STATICFILES_DIRS = ( '/home/username/projects/projectname/static',) Debug is set to True. I have tried it both with and without the staticfiles_urlpatterns trick. Django can find one file in the directory but not the other? I think I'm going crazy.
