• Objective-C FontAwesome

  - by sdover102

  I'm Attempting to get FontAwesome up and running on an iOS app and could use a little assistance. I have the following code for iOS: UIBarButtonItem * viewDeckButton = [[UIBarButtonItem alloc] initWithTitle:@"\uf0c9" style:UIBarButtonItemStyleBordered target:self.viewDeckController action:@selector(toggleLeftView)]; NSDictionary * customTextAttrs = [NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"FontAwesome" size:14.0], UITextAttributeFont, nil]; [viewDeckButton setTitleTextAttributes:customTextAttrs forState:UIControlStateNormal]; @"\uf0c9" corresponds to the css class, icon-reorder. The font appears to be installed on my system (see http://cl.ly/image/2F1x1z2H0i2N). I'm getting the standard box character, as if the font is not loaded (see http://madmonkdev.com/badchar.png). Any help would be appreciated.

• Placing text on UIView in custom location

  - by JAM

  I am trying to calculate a position to place label on the screen. The goal is to place "word" label in lower right corner of the first square block If yellowish square is defined as myView = [[UIView alloc] initWithFrame:CGRectMake(100, 100, 70, 70)]; [self.view addSubview:myView]; [myView setBackgroundColor:[UIColor colorWithHexString:@"FFFFEC"]]; Using it, i'd like to place a label in it's lower right corner l1 = [[UILabel alloc] init]; [l1 setText:@"word"]; [l1 setFrame:CGRectMake(myView.frame.origin.x + myView.frame.size.width, myView.frame.origin.y + myView.frame.size.height, 700, 700)]; [l1 setFont:[UIFont fontWithName:@"Arial" size:10.0]]; [l1 setBackgroundColor:[UIColor colorWithHexString:@"CCFFFEC"]]; [l1 setTextAlignment:UITextAlignmentRight]; [l1 sizeToFit]; This is what happens: The matter here obviously, is in a correct offset. Knowing the font and size of text, how can one correctly calculate it?

• 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!

• Use SQL to clone data in two tables that have a 1-1 relationship with each other

  - by AmoebaMan17

  Using MS SQL 2005, Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H I want to clone the data for GroupID == 1 into a new GroupID so that I result with the following: Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 5 | a | 23 | 3 6 | b | 24 | 3 7 | c | 25 | 3 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H 23 | H 24 | J 25 | K I've found some SQL clone patterns that allow me to clone data in the same table well... but as I start to deal with cloning data in two tables at the same time and then linking up the new rows correctly... that's just not something I feel like I have a good grasp of. I thought I could do some self-joins to deal with this, but I am worried in the cases where the non-key fields have the same data in multiple rows.

• Documents/Images display fine in Simulator, but not on my device

  - by Phamer

  Hello. My application is running fine on the simulator, but not on the device. Basically, any documents from the web (PDF, Word, M4P videos) are working great on the simulator (and can be accessed from Safari on the iPhone). However, running on the iPhone, they don't display anything. Here's some sample code: // Set up the URL documentViewController.documentUrl = [NSURL URLWithString:[NSString stringWithFormat:mobileContentUrl]]; // mobileContentUrl is something like: http://www.myserver.com/pathitem/Video.mp4" and can be accessed from Safari [self.navigationController pushViewController:documentViewController animated:YES]; Within documentViewController I have: - (void)viewDidLoad { [super viewDidLoad]; [webView loadRequest:[NSURLRequest requestWithURL:documentUrl]]; } As I said, works like a charm in the Simulator...What could possibly causing this NOT to work on iPhone? How do I debug the issue???

• Best way to make an attribute always an array?

  - by Shadowfirebird

  I'm using my MOO project to teach myself Test Driven Design, and it's taking me interesting places. For example, I wrote a test that said an attribute on a particular object should always return an array, so -- t = Thing.new("test") p t.names #-> ["test"] t.names = nil p t.names #-> [] The code I have for this is okay, but it doesn't seem terribly ruby to me: class Thing def initialize(names) self.names = names end def names=(n) n = [] if n.nil? n = [n] unless n.instance_of?(Array) @names = n end attr_reader :names end Is there a more elegant, Ruby-ish way of doing this? (NB: if anyone wants to tell me why this is a dumb test to write, that would be interesting too...)

• How can I take zooming into account when a user touches a UIScrollView?

  - by Bill

  I have a UIImageView inside of a UIScrollView. The parent scroll view allows zooming and panning. When the user taps a point in the scroll view, I want to find the location in the raw image inside the UIImageView - i.e. I want the point after including any zooming and panning the user has done in the scroll view. Right now, I have a UIScrollView subclass called ForwardingScrollView that handles touch events and attempts to convert them into locations in the coordinate system of the child image view. I tried adding contentOffset to these points, tried multiplying them by zoomScale, and even tried doing both. I also tried calling [touch locationInView: self] and [touch locationInView: parent], but none of these methods correctly return the point that I clicked in the underlying image. What's the best way to do this? Thanks in advance.

• Multiple HTTP request - Rails

  - by bradleyg

  My application checks a number of domains to see if they are valid (approx 100). I have the following code to check a single domain: def self.test_url uri, limit = 10 if limit == 0 return get_error_messages("001") end begin url = URI.parse(uri) response = Net::HTTP.start(url.host, url.port).request_head('/') rescue SocketError => e return get_error_messages("002") end case response when Net::HTTPRedirection then test_url(response['location'], limit - 1) else return get_error_messages(response.code) end end The code checks for the response code while taking into account redirects. This works fine. The only problem I have is when I put this in a loop I want it to run in parallel. So I don't have to wait for domain 1 to respond before I can request domain 2. I have managed this in PHP using curl_multi to run the requests in parallel. Is there a similar thing I can do in Rails?

• willSelectRowAtIndexPath Question....

  - by treasure

  How do you add a second section (SECOND_SECTION) here to be excluded from selection when editing? (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSIndexPath *rowToSelect = indexPath; NSInteger section = indexPath.section; BOOL isEditing = self.editing; // If editing, don't allow notes to be selected // Not editing: Only allow notes to be selected if ((isEditing && section == ONE_SECTION) || (!isEditing && section != ONE_SECTION)) { [tableView deselectRowAtIndexPath:indexPath animated:YES]; rowToSelect = nil; } return rowToSelect; } it s being driving me nuts... thanks

• C++ Beginner - Simple block of code crashing, reason unknown.

  - by Francisco P.

  Hello everyone, Here's a block of code I'm having trouble with. string Game::tradeRandomPieces(Player & player) { string hand = player.getHand(); string piecesRemoved; size_t index; for (size_t numberOfPiecesToTrade = rand() % hand.size() + 1; numberOfPiecesToTrade != 0; --numberOfPiecesToTrade) { index = rand() % hand.size(); piecesRemoved += hand[index]; hand.erase(index,1); } player.removePiecesFromHand(piecesRemoved); player.fillHand(_deck); return piecesRemoved; } I believe the code is pretty self explanatory. fillhand and removepiecesfromhand are working fine, so that's not it. I really can't get what's wrong with this :( Thanks for your time

• Why the data binding in this validation example works in WPF?

  - by MartyIX

  I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

• [Ruby] Confirm existance of executable (script, bat, cmd, exe) via a ruby file.

  - by srcspider

  Using a ruby file (or any rake facility) I need to find out if the user who executes my script is able to execute certain shell commands. In particular g++ etc. Hopefully system independent so if there is some g++.bat, g++.exe or just g++ (etc) it should say yes nevertheless, as long as its on the path and executable on the users system. Example: if the user has a no-extention executable version of the file and a .cmd version of the file it should say "yes" for the no extension version on a linux system and "yes" to the .cmd version on a windows system. Since the users shell can only execute that version of the file. The purpose of this is to allow the script to be self-configuring (as much as possible). Any suggestions on how I might go about doing this?

• Passing data from one viewcontroller to another

  - by user1392515

  I subclassed two view controllers. The first one is supposed to pass data, a NSUrl object to the second one. .m of the first one: NSURL *temp = [NSURL URLWithString:@"http://example.com"]; UIViewController *presentationsFullScreen_ViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PresentationsFullScreen_ViewController"]; presentationsFullScreen_ViewController.urlToUse = temp; .h of the second one: #import <UIKit/UIKit.h> @interface PresentationsFullScreen_ViewController : UIViewController { NSURL *urlToUse; } @property (nonatomic,retain) NSURL *urlToUse; It is obviously not working and not compiling,telling me essentially that I didn't subclass it and that the property urlToUse is not found on UIViewController. How do I subclass correctly? Thanks!

• How can I call a Perl package I define in the same file?

  - by Robert S. Barnes

  I need to define some modules and use them all in the same file. No, I can't change the requirement. I would like to do something like the following: { package FooObj; sub new { ... } sub add_data { ... } } { package BarObj; use FooObj; sub new { ... # BarObj "has a" FooObj my $self = ( myFoo => FooObj->new() ); ... } sub some_method { ... } } my $bar = BarObj->new(); However, this results in the message: Can't locate FooObj.pm in @INC ... BEGIN failed... How do I get this to work?

• How can I strip non-XHTML tags from a string in C#?

  - by No Average Geek

  I need to be able to remove non-XHTML tags from a string containing XHTML that has been stored in a database. The string also contains references for controls (e.g. ) inside the XHTML, but I need clean XHTML with all standard tag contents unchanged. These control tags are varied (they could be any ASP.NET control), so there are too many to go looking for each one and remove them. The way they are closed is also varied, so not all of them have closing tags, some are self closing. How can I go about doing this? I've found some HTML cleaners on-line for including in my project, but they either remove everything or just HTML encode the entire string. Also, I'm dealing with parts of XHTML documents, not entire documents - don't know if that makes a difference. Any help would be appreciated.

• What are the differences in performance between synchronous and asynchronous JavaScript script loading?

  - by jasdeepkhalsa

  My question is simply: what are the differences in performance between synchronous and asynchronous JavaScript script loading? From what I've gathered synchronous code blocks the loading of a page and/or rest of the code from executing. This happens at two levels. First, at the level of the script actually loading, and secondly, within the JavaScript code itself. For example, on the page: Synchronous: <script src="demo_async.js" type="text/javascript"></script> Asynchronous: <script async src="demo_async.js" type="text/javascript"></script> And within a script: Synchronous: function a() {alert("a"); function b() {alert("b");}} Asynchronous (and self-executing): (function(a, function(b){ alert(b); }) { alert(a); }))(); So what really is the difference in performance from using these different loading methods and JavaScript patterns?

• Static keyboard in uitableview

  - by Martin

  I have a UITableView that holds just two cells with a textfield in each. As my tableview is just for editing the text in these textfields I always want the keyboard to be shown static in the bottom of the screen. So in viewDidLoad I set the first textfield to become first responder. Something I have noticed though is that when I push the UITableViewController into the UINavigationController the keyboard show up a little bit slower so you can see it animate into the screen. It would be much better if it was there already there when the uitableview shows up. I also tried making the textfield first responder before pushing it as recommended but that didn't made the keyboard show at all: MyTableViewController *myTableViewController = [[MyTableViewController alloc] initWithNibName:@"MyTableViewController" bundle:nil]; [myTableViewController.textField becomeFirstResponder]; [self.navigationController pushViewController:myTableViewController animated:YES]; [myTableViewController release]; How can I accomplish this? Thanks!

• couchdb: one database per account vs all in one database w. a namespace / property

  - by thruflo

  I'm modelling a document generation system in couchdb. It semi-automates the production of proposal and presentation documents from managable document fragments. Much like, say, Basecamp, it breaks down very simply into self-contained data per 'account'. Each account has multiple users, projects, documents, etc. However, nothing should be shared between accounts. I can see two ways of doing this: one couchdb database per account use a namespace / property to identify the account It seems to me that the first approach is conceptually sound and potentially has security and partitioning advantages. However, it seems to me to restrict some cross-database data querying (that I don't have a use case for now but you never know...) and to make updating views potentially require an awful lot of writes. Does anyone experienced with this kind of decision have any advice?

• What do C# Table Adapters actually return?

  - by Raven Dreamer

  I'm working on an application that manipulates SQL tables in a windows form application. Up until now, I've only been using the pre-generated Fill queries, and self-made update and delete queries (which return nothing). I am interested in storing the value of a single value from a single column (an 'nchar(15)' name), and though I have easily written the SQL code to return that value to the application, I have no idea what it will be returned as. SELECT [Contact First Name] FROM ContactSkillSet WHERE [Contact ID] = @CurrentID Can the result be stored directly as a string? Do I need to cast it? Invoke a toString method?

• What is a good way for a custom accessory view in a UITableViewCell to message the table view contro

  - by Alex Gosselin

  Hi Everyone, I am working on adding a custom accessory view, (a button) to a UITableViewCell, and I need it to tell the table view when it is touched, but I can't figure out how to communicate to the table view what button was pressed. Ideally I'd like to somehow call a function like this: [controller tableView:view didSelectCustomButtonAtIndexPath:indexPath usingCell:self]; when my custom view button is pressed. Sorry if this is a bit vague, I'm not really sure how to explain this well. I am basically looking for how to mimic the implementation for tableView:didSelectRowAtIndexPath: without having to subclass UITableViewCell. Thanks for any help.

• How to map an property of ClassA to one of SuperclassA?

  - by mystify

  I have a class named SuperclassA, and an class named ClassA. ClassA inherits from SuperclassA. SuperclassA has got an property called something, so a very generic not-much-saying name. In ClassA, I want to have an property which maps to that something of SuperclassA. How could I do that? I want to make absolutely sure that any access to myBetterProperty results in accessing what's behind something. Assigning an value to myBetterProperty should result in assigning one to something, and vice versa. How to? Pointers set up in init? How would that look like? *self.myBetterProperty = &something; ? I'm not sure about that...

• dynamically double image size

  I have an embarrassingly simple question: How can I display an image at double its size without hard coding the width and height attributes? Here's what I tried, but I ended up having to just enter 1000 for width and height. Is something wrong with my function? Thanks! <img onload="double(self.id);" name="bigPic" id="bigPic" src="album1.jpg" height="1000" width="1000"/> function double(id) { var img = document.getElementById(id); var dblWdth = img.width * 2; var dblHt = img.height * 2; img.height = dblHt; img.width = dblWdth; }
