  • Stack Info button above UIView in Utility App

    - by bgw
    I've started creating a iPhone Utility app (main view and flip view). I want to draw some graphics in the Main view, so I dragged a UIView object onto it. This works, but I find that if I resize the UIView to fill the Main view, it covers the Info button that invokes the Flip view. Is there any way to get the Info button to appear on top of the UIView? In IB? In code?

  • how to convert legacy query to ActiveRecord Rails way

    - by josh
    I have a query in my code as below @sqladdpayment = "INSERT INTO payments (orderid, ttlprodcost, paytype, paystatus,created_at,updated_at,userid,storeid) VALUES ('" + session[:ordersid] + "', '" + session[:totalcost] + "', '" + "1"+ "', '" + "complete" +"',current_date, current_date, '"+"1"+"','"+ "1"+"')" Here the table payments and primary key is orderid. Now, I know if I convert this to the ActiveRecord way then I will not have to put update_date, current_date because it will put that on it's own. It will also put orderid on it's own also (auto_increment). I am looking for a way to convert the above query to ActiveRecord Rails way but still be able to put orderid on my own (session[:ordersid]). I do not want to rely on auto_increment because then I will have to refactor lot of the other code. This might be a quick and dirty fix but I want to know whether this type of flexibility is offered in rails? I have wondered about this question many times. Why won't rails allow me to have that flexibility?

  • Repeater not working fine when passed a dataprovider (array) having a single element

    - by baltusaj
    I am using a Repeater in an Accordian which does not appear to see a single element in userArray. If I add another entry to userArray then the Repeater works fine. Thoughts?? private function currUsersServiceHandler(event:ResultEvent):void{ if (event.result.currentUsers != null) { if (event.result.currentUsers.user is ArrayCollection) // if more than one elements are present { usersArray = event.result.currentUsers.user; } else if (event.result.currentUsers is ObjectProxy) { //FIXIT usersArray populate by following line has some issue usersArray = new ArrayCollection(ArrayUtil.toArray(event.result.currentUsers)); } } } <mx:HTTPService id="currUsersService" url="currUsers.xml" result="currUsersServiceHandler(event)"/> <mx:Accordion includeIn="UserList" x="10" y="10" width="554" height="242" > <mx:Repeater id="rep" dataProvider="{usersArray}"> <mx:Canvas width="100%" height="100%" label="{rep.currentItem.firstName}" > <mx:HBox> <s:Label text="{rep.currentItem.firstName}"/> <s:Label text="{rep.currentItem.lastName}"/> <mx:/HBox> </mx:Canvas> </mx:Repeater> </mx:Accordian> Edit: There is another thing I have just noticed i.e. that the accordian does show a single tab (when Array has a single element) but it's not labeled with the first name which I am setting. If I enter another user, two tabs appear and both are labeled with names I am setting. The first tab appears labeled too then.

  • mysql PHP query question

    - by camran
    Ok, i have a problem here... I am sending values of drop down lists via ajax to this PHP file. Now I want to search a mysql database using these values, which I have managed to do, BUT, only if I set the values to something... Take a look: $query = "SELECT * FROM cars_db WHERE price BETWEEN '$cars_price_from' AND '$cars_price_to' AND year BETWEEN '$cars_year_from' AND '$cars_year_to' AND mileage BETWEEN '$cars_mileage_from' AND '$cars_mileage_to' AND gearbox = '$cars_gearbox' AND fuel = '$cars_fuel'"; now, what if the user doesnt select any "price_from" or "year_from"... The fields are only optional, so if the user doesnt enter any "price from" or "year from", then the user wants ALL cars to show... Do I have to write a query statement for each case or is there another way?

  • Control ( UIButton, UILable) Hides when the Video plays Again on iPhone!

    - by Taimur Hamza
    Hi, I have displayed UIButton on top of Playing Movie using this code. NSArray *windows = [[UIApplication sharedApplication] windows]; if ([windows count] 1) { // Locate the movie player window UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; // Add our overlay view to the movie player's subviews so it is // displayed above it. [moviePlayerWindow addSubview:self.myABC]; } There are 2 buttons on top of my movie layer. They play different videos.Now the strange part is the video plays fine with buttons showing on top of it. When i press the button to play the other movie plays but the buttons doesnt show. Seems the view reloads and flushes all the Subviews. But i have checked it in the debug mode and it enters into the 'if' condition and this line runs [moviePlayerWindow addSubview:self.myABC]; But the buttons are not dislpayed. Any ideas wats going wrong ? Thanks, Taimur

  • get foreign key objects in a single query - Django

    - by John
    Hi I have 2 models in my django code: class ModelA(models.Model): name = models.CharField(max_length=255) description = models.CharField(max_length=255) created_by = models.ForeignKey(User) class ModelB(models.Model): category = models.CharField(max_length=255) modela_link = models.ForeignKey(ModelA, 'modelb_link') functions = models.CharField(max_length=255) created_by = models.ForeignKey(User) Say ModelA has 100 records, all of which may or may not have links to ModelB Now say I want to get a list of every ModelA record along with the data from ModelB I would do: list_a = ModelA.objects.all() Then to get the data for ModelB I would have to do for i in list_a: i.additional_data = i.modelb_link.all() However this runs a query on every instance of i. Thus making 101 queries to run. Is there any way of running this all in just 1 query. Or at least less than the 101 queries. I've tried putting in ModelA.objects.select_related().all() but this didn't seem to have any effect. Thanks

    - by rubdottocom
    I have a query that returns a large number of heavy rows. When I transform this rows in a list of CustomObject I have a big memory peak, and this transformation is made by a custom dotnet framework that I can't modify. I need to retrieve a less number of rows to do "the transform" in two passes and then avoid the momery peak. How can I split the result of a query by half? I need to do it in DB layer. I thing to do a "Top count(*)/2" but how to get the other half? Thank you!

  • Problem when exiting search in iPhone

    - by camilo
    Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!

  • Removing groups of similar records in MySQL query

    - by user1182155
    I'm trying to wrap my head around this... (it may be simple, been a long day!) I have a database with sometimes multiple similar records... ie. Apples 2008-09-03 Apples 2012-01-01 Apples 2013-10-24 Oranges 2012-01-04 What I need to do is do a query that will show only records that haven't been updated today... So in this case, since Apples has an entry that was updated today, none of the records for the Apples should appear in the results. Oranges should be the only record it returns. I have a query similar to this... SELECT fruit FROM fruitnames where date < CURDATE() Which works to remove the record that was updated today... But it keeps the other records for Apples (obviously)... How would I remove those results as well?

  • IBOutlets are always nil

    - by Jonas
    Hi, In IB I have subclassed the File Owner and the subclass loads my .nib. The subclass itself doesn't need access to the IBOutlets so they're instance variables in another class, which I added as a subclass of NSObject in the .nib. Then I connected the interface elements to that object. But somehow, in the class that "owns" the IBOutlets, they show up as nil. What am I doing wrong here?

  • Same object in different nib files?

    - by Michael
    View1 object, which is UIViewController subclass is the same object as File's Owner of View1 nib. So I should manually set the class in both places, one in MainWindow and another in View1 nib files? This sound artificial to me... Either I'm doing something wrong or there has to be better way.

  • Can I do this in only one query ?

    - by Paté
    Merry christmas everyone, I Know my way around SQL but I'm having a hard time figuring this one out. First here are my tables (examples) User id name friend from //userid to //userid If user 1 is friend with user 10 then you a row with 1,10. User 1 cannot be friend with user 10 if user 10 is not friend with user 1 so you have 1,10 10,1 It may look weird but I need those two rows per relations. Now I'm trying to make a query to select the users that have the most mutual friend with a given user. For example User 1 is friend with user 10,9 and 7 and user 8 is friend with 10,9 and 7 too ,I want to suggest user 1 to invite him (like facebook). I want to get like the 10 first people with the most mutual friend. The output would be like User,NumOfMutualFriends I dont know if that can be done in a single query ? Thanks in advance for any help.

  • If statement in MySQL query with PHP

    Is it possible to use an if statement in a MySQL query in a similar what I'm showing? I want to grab some information for upcoming events(not ones with previous dates). ini_set('date.timezone', 'America/New_York'); $timestamp = date('m/d/Y'); $sql = "select eventID,eventTitle,eventDate from events where eventLocationID = $locationID ORDER BY eventDate DESC IF(eventDate > $timestamp) "; I really want to avoid doing post-query if statements that will only print if it's after today's date because I run it through a pagination function, and I'd really prefer to avoid tinkering with that.
