• How to show/hide UIImageView when I want.

  - by Madness64

  I'm having a little problem with an iPhone app I'm currently developing. When the user touch a button, it calls an IBAction named refreshQuestion, which is supposed to show an image hover the screen to ask the user to wait a moment, then it has to call another function, and finally it has to hide the image. The problem is that the image won't appear. As well as the network activity indicator. Any help? Here is the code : - (IBAction)refreshQuestion:(id)sender{ pleaseWait.hidden = NO; [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; [self loadData]; pleaseWait.hidden = YES; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; }

• Build multiple sources into multiple targets in a directory

  - by Taschetto

  folks. I'm learning about GNU-Make and I have the following project structure: ~/projects /sysCalls ex1.c ex2.c ex3.c ex4.c ex5.c ex6.c ex7.c Each .c source is very simple, has its own main function and must be built into a corresponding binary (preferably named after its source). But I want to build into a bin directory (added to my .gitignore file). My current Makefile is: CC := gcc CFLAGS := -Wall -g SRC := $(wildcard *.c) TARGET := $(SRC:.c=) all: bin $(TARGET) mv $(TARGET) bin/ bin: mkdir bin clean: rm -fr bin/ It works as expected, but always builds every source. And I don't like moving everything to bin "manually". Any tips or ideas on how this Makefile could be improved?

• Query for multiple joins

  - by Shailaja

  i have 3 tables named dataset,dataelem and transformdataelem with column names as below: main.Dataset ------------ datasetID (PK) applicationID main.Dataelem ------------- dataelemID(PK) datasetID(FK) dataelemname biztermID main.Transformdataelem ---------------------- OutputdataelemID InputdataelemID My requirement is: All tables are referenced. Extract all the dataelemId rows from dataelem table where applicationID of dataset table is equal to 1044 and biztermid shud be null. Then whatever resultant dataelemIDs from the above query should be matched with outputdataelemID of Transformdataelem table and we shud get the respective input dataelemId's. Again with these matched inputdataelemID's we shud get the dataelemname's from datelem table.

  I want to have a property on my custom control that is an interface type.

• Some help needed with a SQL query

  - by Psyche

  Hello, I need some help with a MySQL query. I have two tables, one with offers and one with statuses. An offer can has one or more statuses. What I would like to do is get all the offers and their latest status. For each status there's a table field named 'added' which can be used for sorting. I know this can be easily done with two queries, but I need to make it with only one because I also have to apply some filters later in the project. Here's my setup: CREATE TABLE `test`.`offers` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY , `client` TEXT NOT NULL , `products` TEXT NOT NULL , `contact` TEXT NOT NULL ) ENGINE = MYISAM ; CREATE TABLE `statuses` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `offer_id` int(11) NOT NULL, `options` text NOT NULL, `deadline` date NOT NULL, `added` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1

• What is the best way to handle dynamic content_type in Sinatra

  - by lusis

  I'm currently doing the following but it feels "kludgy": module Sinatra module DynFormat def dform(data,ct) if ct == 'xml';return data.to_xml;end if ct == 'json';return data.to_json;end end end helpers DynFormat end My goal is to plan ahead. Right now we're only working with XML for this particular web service but we want to move over to JSON as soon as all the components in our stack support it. Here's a sample route: get '/api/people/named/:name/:format' do format = params[:format] h = {'xml' => 'text/xml','json' => 'application/json'} content_type h[format], :charset => 'utf-8' person = params[:name] salesperson = Salespeople.find(:all, :conditions => ['name LIKE ?', "%#{person}%"]) "#{dform(salesperson,format)}" end It just feels like I'm not doing it the best way possible.

• How to create an formatted localized string?

  - by mystify

  I have an localized string which needs to take a few variables. However, in localization it is important that the order of the variables can change from language to language. So this is not a good idea: NSString *text = NSLocalizedString(@"My birthday is at %@ %@ in %@", nil); In some languages some words come before others, while in others it's reverse. I lack of an good example for the moment. How would I provide NAMED variables in an formatted string? Is there any way to do it without some heavy self-made string replacements? Even some numbered variables like {%@1}, {%@2}, and so on would be sufficient... is there a solution?

• AS3 Components in Flash Designer

  - by Jack Voight

  In an ActionScript 2 project I can create a new MovieClip, right-click on it on the library and select "Component Definition" to add parameters that can be referenced inside the MovieClip. This parameters can be easily changed in the MovieClips's properties. Now, I'm working on an ActionScript 3 project but haven't been able to figure out a way to obtain the values passed in those parameters. I defined a parameter named "textToDisplay" but when I write the following in the Actions for the first frame I get an error: trace(textToDisplay); This is the error: 1120: Access of undefined property textToDisplay. Do you know how to capture the value of that parameter? Thanks PS: I'm using Adobe Flash CS3 Professional on Windows XP

• need help in aggregate select

  - by eugeneK

  Hi, i have a problem with selecting some values from my DB. DB is in design stages so i can redesign it a bit of needed. You can see the Diagram on this image Basically what i want to select is select c.campaignID, ct.campaignTypeName, c.campaignName, c.campaignDailyBudget, c.campaignTotalBudget, c.campaignCPC, c.date, cs.campaignStatusName ***impressions, ***clicks, ***cast(campaignTotalBudget-(clicks*campaignCPC) as decimal(18,1)) as remainingFunds from Campaigns as c left join CampaignTypes as ct on c.campaignTypeID=ct.campaignTypeID left join CampaignStatuses as cs on c.campaignStatusID=cs.campaignStatusID left join CampaignVariants as cv on c.campaignID=cv.campaignID left join CampaignVariants2Visitors as c2v on cv.campaignVariantID=c2v.campaignVariantID left join Visitors as v on c2v.visitorID=v.visitorID ..... order by c.campaignID desc Problem is that Visitors table has column named isClick so i don't know the way to separate what is impression with isClick=false and what is click isClick=true so i can show nice form with all the stuff about campaign and visitors... I don't think to split Visitors to two tables like Impressions and Click is a good idea because again i would need to have Visitors with two more tables thanks

  Hi, I have a model I named User, and I want use two different Views to edit it: the usual edit view and another view I called edit_profile. I had no problem in creating routing, controller and views: I added edit_profile and update_profile views, and I added on routes.rb the line: map.resources :users ,:member => {:edit_profile => :get, :update_profile => :put} The problem is: when I submit the form in edit_profile and some error occur in some input fields, rails reload the edit_path page instead of edit_profile_path page !

• Android - BaseGameUtil Complicated Import

  - by Fabiow Quixadá

  I've seen many topics in stackoverflow, such as Cannot import BaseGameUtils (Eclipse weirdness) and Android: cannot import BaseGameUtils successfully in Eclipse but none resolved my problem. I've followed https://developer.android.com/google/play-services/setup.html#Setup - the Add Google Play Services to Your Project [Using Eclipse with ADT], I THINK my project correctly references the google play services lib since up to that point nothing wrong happened. Then, following https://developers.google.com/games/services/android/quickstart, I've downloaded BaseGameUtils but when I import the two projects [TypeANumber & BaseGameUtil], they came named as main and MainActivity. I've renamed BaseGameUtil as so and have marked it as lib and imported it to my project through Properties Android Library, but I can't extend extend a class from BaseGameUtil because it's not even suggested. Also, I have not installed Android L and Android 4.4W from SDK Manager in Eclipse, altough I think that's no the case. Can anyone please help in this? Thanks so much in advance

• How to use ccache selectively?

  - by Anonymous

  I have to compile multiple versions of an app written in C++ and I think to use ccache for speeding up the process. ccache howtos have examples which suggest to create symlinks named gcc, g++ etc and make sure they appear in PATH before the original gcc binaries, so ccache is used instead. So far so good, but I'd like to use ccache only when compiling this particular app, not always. Of course, I can write a shell script that will try to create these symlinks every time I want to compile the app and will delete them when the app is compiled. But this looks like filesystem abuse to me. Are there better ways to use ccache selectively, not always? For compilation of a single source code file, I could just manually call ccache instead of gcc and be done, but I have to deal with a complex app that uses an automated build system for multiple source code files.

• Enter a letter when prompted by another command

  - by kij

  Hi all, I'm trying to automate the installation and deployement of an application. To do it, i have a shell script with the following instructions: /usr/local/bin/amf install -u $1 -p $2 $localTarget where $1, $2 and $localTarget are options for the command named 'amf'. The problem is that the 'amf' command make severall instructions and ask the user to enter a letter during those instructions (to confirm the installation). At the moment, i can't bypass or modify the behaviour of the 'amf' command, so my question is: How can i catch this behaviour and/or automatically enter a letter in my script. This behaviour currently make my script not working, because the 'amf instal...' instruction is followed by another command to start my application. But as the install failed, the application can't start. Thanks in advance for your help. Best regards. Kij.

• How to open an html file using the default file handler and to give the window a name (i.e. target)?

  - by paul

  I am writing a warm-up script for a SharePoint server. The idea is to call stsadm and then open an html file containing iframes which touch all the key web pages in my portal. So far so good. The problem is that each time the script is run, a new browser window is opened and I end up with a screen full of browsers. The first idea was to close the browser after 10 minutes or so. This would be easy to do except that Javascript is disabled when an html file is opened from the file system. I then thought I might be able to open the file and set it in a named window (target) which would be reused each time the script runs but I haven't found any way to do this. Does anyone have any ideas? Either to force JS to run or to set the window name or another solution? Thanks.

• How can I set my root directory based on a cookie?

  - by Kacey

  I'm attempting to use my htaccess file to set my root folder based on a cookie that is set through the website. Unfortunately, I haven't been able to find any information on how to do this. Here is what I have tried doing, which I know is incorrect, but it was the best I could find to work with. RewriteCond %{HTTP_HOST} ^(www\.)?domain\.(int|com)$ [NC,OR] RewriteCond %{REQUEST_URI} !^/s3i.flat/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{HTTP_COOKIE} s=n2014 [NC] RewriteRule ^(.*)$ /s3i.flat/$1 RewriteRule ^(.*)$ /s3i.2014/$1 RewriteCond %{HTTP_HOST} ^(www\.)?domain\.(int|com)$ [NC] RewriteCond %{HTTP_COOKIE} s=n2014 [NC] RewriteRule ^(/)?$ s3i.flat/ [L] RewriteRule ^(/)?$ s3i.2014/ [L] What I'm trying to do is use the s3i.flat directory if the cookie named s is equal to n2014, and the other directory if the cookie is not set, or does not equal that. Is anyone aware of a way that this can be done? Thanks in advance.
