• How to update multiple rows with one single query

  - by xRobot

  I use Postgresql + PHP. Say I have this table: Books ( id, title, year ) and this array of titles in PHP: $titles = array ("bible","kafka","Book of Eli"); now I want update all rows where the title is in the $titles array above. So I need a query like this: UPDATE books SET year = '2001-11-11' WHERE title is in $titles; Is is possible with one single query ? Or do I need to use FOR loop ?

• CustomValidatation control that fire on multiple control events

  - by George

  I am trying to create a UserControl that is a composite control for entering Dates. It involves 2 drop down controls (one for month and one for day) and a text box for year. It also has a CustomValidation control that I would like the user of the UserControl to be able to set the ClientValidationFunction property and have it triggered whenever the value in any of the 3 date part controls changes. To hook up each of the 3 controls to the validation control, I use teh AJAX ValidatorHookupControlID method. If I hard code the following code directly in my aspx page that houses the usercontrol, my Client Validation Function is successfulluy called when any of the 3 date part control values are changed: <script type="text/javascript"> //<![CDATA[ debugger; alert('hooking up'); ValidatorHookupControlID("ctl00_phPageContent_dtmPassportExpirationDate_txtYear", document.all("ctl00_phPageContent_dtmPassportExpirationDate_CustomValidator1")); ValidatorHookupControlID("ctl00_phPageContent_dtmPassportExpirationDate_ddlDate", document.all("ctl00_phPageContent_dtmPassportExpirationDate_CustomValidator1")); ValidatorHookupControlID("ctl00_phPageContent_dtmPassportExpirationDate_ddlMonth", document.all("ctl00_phPageContent_dtmPassportExpirationDate_CustomValidator1")); //]]> However, I would like my usercontrol to emit this Javascript, so I added the following Code. Public Property ClientValidationFunction() As String Get Return CustomValidator1.ClientValidationFunction End Get Set(ByVal value As String) CustomValidator1.ClientValidationFunction = value End Set End Property Public Property EnableClientScript() As Boolean Get Return CustomValidator1.EnableClientScript End Get Set(ByVal value As Boolean) CustomValidator1.EnableClientScript = value End Set End Property Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender If Me.ClientValidationFunction.Trim <> "" AndAlso Me.EnableClientScript Then RegisterValidationScript() End If End Sub Private Sub RegisterValidationScript() Dim Key As String = Me.ClientID & "_ClientValidate" If Not Page.ClientScript.IsClientScriptBlockRegistered(Key) Then Page.ClientScript.RegisterClientScriptBlock(GetType(String), Key, GetJavascript, True) End If End Sub Private Function GetJavascript() As String Dim Out As String = "" Const Quote As String = Chr(34) Out &= "debugger;" & vbCrLf Out &= "ValidatorHookupControlID(" & Quote & txtYear.ClientID & Quote & ", document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf Out &= "ValidatorHookupControlID(" & Quote & ddlDate.ClientID & Quote & ", document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf Out &= "ValidatorHookupControlID(" & Quote & ddlMonth.ClientID & Quote & ", document.all(" & Quote & CustomValidator1.ClientID & Quote & "));" & vbCrLf Return Out End Function Unfortunately, when the ValidatorHookupControlID method is called, the second parameter (the one that locates the validation control) always evaluates to null and the method fails. ValidatorHookupControlID("ctl00_phPageContent_DateSelector21_txtYear", document.all("ctl00_phPageContent_DateSelector21_CustomValidator1")); Can you tell me how to correct this error?

• Configuring Multiple ASP.NET MVC Sites To Use a Single Database For Authentication/Membership

  - by Maxim Z.

  Is it possible for two or more ASP.NET MVC sites to use a single SQL Server database for authentication and other things? Here's how I'm thinking of setting it up: I will combine the current database of each site into one single database, prefixing the tables with the name of the site they belong to. I currently have authentication tables generated by the asp.net_regsql.exe utility. How should I combine those tables? I'm guessing that the way to do it is to somehow set the "application_id" column in those tables... Thanks in advance.

• Rails named_scope across multiple tables

  - by wakiki

  I'm trying to tidy up my code by using named_scopes in Rails 2.3.x but where I'm struggling with the has_many :through associations. I'm wondering if I'm putting the scopes in the wrong place... Here's some pseudo code below. The problem is that the :accepted named scope is replicated twice... I could of course call :accepted something different but these are the statuses on the table and it seems wrong to call them something different. Can anyone shed light on whether I'm doing the following correctly or not? I know Rails 3 is out but it's still in beta and it's a big project I'm doing so I can't use it in production yet. class Person < ActiveRecord::Base has_many :connections has_many :contacts, :through => :connections named_scope :accepted, :conditions => ["connections.status = ?", Connection::ACCEPTED] # the :accepted named_scope is duplicated named_scope :accepted, :conditions => ["memberships.status = ?", Membership::ACCEPTED] end class Group < ActiveRecord::Base has_many :memberships has_many :members, :through => :memberships end class Connection < ActiveRecord::Base belongs_to :person belongs_to :contact, :class_name => "Person", :foreign_key => "contact_id" end class Membership < ActiveRecord::Base belongs_to :person belongs_to :group end I'm trying to run something like person.contacts.accepted and group.members.accepted which are two different things. Shouldn't the named_scopes be in the Membership and Connection classes? One solution is to just call the two different named scope something different in the Person class or even to create separate associations (ie. has_many :accepted_members and has_many :accepted_contacts) but it seems hackish and in reality I have many more than just accepted (ie. banned members, ignored connections, pending, requested etc etc)

• Creating xaml 'template' for multiple pages

  - by superexsl

  Hey, I'm developing a Silverlight application for the first time. I've gone through some tutorials, but I can't seem to find anything that helps me with this particular problem. I would like a set of buttons to be present on all of my pages (like a template). When a button is pressed, I would like the ContentGrid to slide out and a new ContentGrid slide in (with the relevant .xaml file being loaded). Are there any tutorials showing the best way to do this? From samples I've seen, they only seem to transition between two pages, so copy-pasting the group of buttons on each xaml page isn't too much of a problem. However, with more pages, it would be inefficient to copy-paste the base layout each time. Thanks for any suggestions

• Dropdown dependent values to be fetch from multiple models using ajax in Yii

  - by newuser

  I searched all the documentation over Yii but not got the answer of it.So I came here finally. I have the following schema Table Schools +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_name | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ Table Students +------------------+--------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+--------------+------+-----+---------------------+----------------+ | id | int(10) | NO | PRI | NULL | auto_increment | | school_id | int(10) | NO | FK | | | | student_name | varchar(100) | NO | | | | | roll_no | varchar(80) | NO | | | | | class | varchar(20) | NO | | | | | | subjects | varchar(100) | NO | | | | +------------------+--------------+------+-----+---------------------+----------------+ I have made models and CRUD for the both models.In models my relation is like this In Students.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'School' => array(self::BELONGS_TO,'Schools','school_id'), ); } In Schools.php the relation is like public function relations() { // NOTE: you may need to adjust the relation name and the related // class name for the relations automatically generated below. return array( 'student' => array(self::HAS_MANY, 'Students', 'school_id'), ); } Now I made the two models rendered in a single page so that I can enter all the respective fields in a single form. In the _form.php file of Students I have made some change in student_name like this <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php echo $form->dropdownList($model,'student_name', CHtml::listData(Students::model()->findAll(), 'id', 'student_name'), array('empty'=>array('Select'=>'--Select One---'))); ?> <?php echo $form->error($model,'student_name'); ?> Now for this piece of code I got all the student name from the Student model. So my problem is when I am getting the student name from the dropdown list and going to select a student it will also fetch all the respective values of the student to be rendered in the _form.php without click on save button.So that user don't have to put it again manually. I think ajax and json encode will work here but don't know how to make them work here. [Update] Here is StudentsController code public function actionDisCoor() { $model = School::model()->findByPk($_POST['Students']['student_id']); $data=CHtml::listData($data,'id','name'); foreach($data as $value=>$name) { echo CHtml::tag('option',array('value'=>$value),CHtml::encode($name),true); } } Here is _form.php code for Students <div class="row"> <?php echo $form->labelEx($model,'student_name'); ?> <?php $List = CHtml::listData(Students::model()->findAll(), 'id', 'student_name'); ?> <?php echo $form->dropdownList($model,'student_name',$List, array('onChange'=>CHtml::ajax(array( 'url' => CController::createUrl('DisCoor'), 'type' => 'POST', 'update'=>'#school_id', )),'style'=>'width:180px;' ) )?> <?php echo $form->error($model,'student_name'); ?> </div> After all that when I saw in firebug I got the error.Here is the screen shot

• Combining multiple content types into a single search result with Drupal 6 and Views 2

  - by Chaulky

  Hi all, I need to create a somewhat advanced search functionality for my Drupal 6 site. I have a one-to-many relationship between two content types and need to search them, respecting that relationship. To make things more clear... I have content types TypeX and TypeY. TypeY has a node reference CCK field that relates it to a single node of TypeX. So, many nodes of TypeY reference the same node of TypeX. I want to use Views 2 to create a search page for these nodes. I want each search result to be a node of TypeX, along with all the nodes of TypeY that reference it. I know I could just theme the individual results and use a view to add the nodes of TypeY to the single node of TypeX... but that won't allow users to actually search TypeY... it would only search TypeX and merely display some nodes of TypeY along with it. Is there anyway to get the search to account for content in nodes of both content types, but merge the TypeY results into the "parent" node of TypeX? In database terms, it seems like I need to do a join, then filter by the search terms. But I can't figure out how to do this in Views. Thanks for any help i can get!!!

• URLRewriter.net with multiple querystring separated by /

  - by Andreas Strandfelt

  I have been looking around the site a bit, but I didn't find any replies on how to do it the way I want. What I want is an URL like this: www.example.com/Projects/"querystring1 - text only"/"querystring2 - 4 digits only"/ to show the page with this URL: www.example.com/Projects.aspx?Region=querystring1&Zip=querystring2 What I have been trying is the following: <rewrite url="~/Leje-og-udlejning-arbejdskraft/(.+)/(.+)" to="~/Workers.aspx?Region=$1&amp;zip=$2"/> But it just takes both of them as one querysting and put them in the Region-querystring.

• MySQL query count multiple values

  - by Sqlclown

  Consider the following DB table: c p ========= 1 'a' 1 'b' 2 'a' 2 'c' Now, my goal is to retrieve a list of numbers c, for which holds that each number in this list has at least a record with p='a' AND p='b'. In the example table above, that would be c=1. Now my question is, how do I accomplish this using one MySQL query?

• Multiple responses from identical calls in asynch QUnit + Mockjax tests

  - by NickL

  I'm trying to test some jQuery ajax code using QUnit and Mockjax and have it return different JSON for different tests, like this: $(document).ready(function() { function functionToTest() { return $.getJSON('/echo/json/', { json: JSON.stringify({ "won't": "run" }) }); } module("first"); test("first test", function() { stop(); $.mockjax({ url: '/echo/json/', responseText: JSON.stringify({ hello: 'HEYO!' }) }); functionToTest().done(function(json) { ok(true, json.hello); start(); }); }); test("second test", function() { stop(); $.mockjax({ url: '/echo/json/', responseText: JSON.stringify({ hello: 'HELL NO!' }) }); functionToTest().done(function(json) { ok(true, json.hello); start(); }); }); }); Unfortunately it returns the same response for each call, and order can't be guaranteed, so was wondering how I could set it up so that it was coupled to the actual request and came up with this: $.mockjax({ url: '/echo/json/', response: function(settings) { if (JSON.parse(settings.data.json).order === 1) { this.responseText = JSON.stringify({ hello: 'HEYO!' }); } else { this.responseText = JSON.stringify({ hello: 'HELL NO!' }); } } }); This relies on parameters being sent to the server, but what about requests without parameters, where I still need to test different responses? Is there a way to use QUnit's setup/teardown to do this?

• Bind multiple request parameters to one object in Spring 3

  - by Max

  Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

• belongs_to with multiple models

  - by julie p

  Hi there! I am a Rails noob and have a question. I have a feed aggregator that is organized by this general concept: Feed Category (books, electronics, etc) Feed Site Section (home page, books page, etc) Feed (the feed itself) Feed Entry So: class Category < ActiveRecord::Base has_many :feeds has_many :feed_entries, :through => :feeds, :limit => 5 validates_presence_of :name attr_accessible :name, :id end class Section < ActiveRecord::Base has_many :feeds has_many :feed_entries, :through => :feeds, :limit => 5 attr_accessible :name, :id end class Feed < ActiveRecord::Base belongs_to :categories belongs_to :sections has_many :feed_entries validates_presence_of :name, :feed_url attr_accessible :name, :feed_url, :category_id, :section_id end class FeedEntry < ActiveRecord::Base belongs_to :feed belongs_to :category belongs_to :section validates_presence_of :title, :url end Make sense? Now, in my index page, I want to basically say... If you are in the Category Books, on the Home Page Section, give me the feed entries grouped by Feed... In my controller: def index @section = Section.find_by_name("Home Page") @books = Category.find_by_name("Books") end In my view: <%= render :partial => 'feed_list', :locals => {:feed_group => @books.feeds} -%> This partial will spit out the markup for each feed entry in the @books collection of Feeds. Now what I need to do is somehow combine the @books with the @section... I tried this: <%= render :partial => 'feed_list', :locals => {:feed_group => @books.feeds(:section_id => @section.id)} -%> But it isn't limiting by the section ID. I've confirmed the section ID by using the same code in the console... Make sense? Any advice? Thanks!

• How do I add a column that displays the number of distinct rows to this query?

• How to prevent parallel builds per build configuration across multiple Build Agents

  - by vanslly

  I have many build configurations in TeamCity, each servicing a large project. In the past if a build is kicked off the Build Agent could be busy for up to 20min! In order to improve throughput I installed a second Build Agent on the same machine such that if a build run is kicked off by say Build Agent 1 and it is busy for 20min and someone from another project makes a change then Build Agent 2 can do the build for the other project without needing to wait on the current build run to finish. All was well until two successive check-ins resulted in both Build Agents running a build for a single build configuration in parallel. Since some resources are shared, IIS directories & databases, I don't want a single build configuration to run on both Build Agents in parallel. How can I ensure a build isn't triggered if a build is currently running for that build configuration on a different build agent? One way seems to involve environmental variables and ensuring a 50/50 split by Build Agent in terms of build configuration compatibility, but that seems a little clunky.

• Flex wordwrap issue with multiple text instances

  - by Craig Myles

  Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

  Usually I'm using One-to-many relationship by this way : class Subject { static hasMany = [ crfs : Crf ] String name ... } class Crf { String title String info ... } I can extend this relationship to others domains, Ex : static hasMany = [ crfs : Crf, crfb : CrfBlood ...] But in my case I have to link the Subject domain to 30 others domains, maybe more...(ex : CrfBlood, CrfMedical, crfFamily, etc...). What domain model implementation should I use in my case ? I would like to keep the dynamic finders usability in my project.

• Hibernate N+1 from select across multiple tables

  - by Marty Pitt

  Given the following hibernate query: String sql = "select distinct changeset " + "from Changeset changeset " + "join fetch changeset.changeEntries as changeEntry " + "join fetch changeEntry.repositoryEntity as repositoryEntity " + "join fetch repositoryEntity.project as project " + "join fetch changeset.author as changesetAuthor " + "where project.id = :projectID "; Why is this resulting in an N+1 problem? I expect this to generate the following single SQL statement (or something similar) select * from Changeset inner join changeEntry on changeset.id = changeEntry.changeset_id inner join repositoryEntity on changeEntry.repositoryentity_id = repositoryentity.id inner join project on repositoryentity.project_id = project.id where project.id = ? Instead, I see many many select statements firing. The data model here looks like this: I would like the full object graph returned from the Select statement in a single trip to the database, which is why I'm explicitly using "fetch" in the hibernate query. The Hibernate log statements are as follows: Hibernate: select distinct changeset0_.id as id2_0_, changeentr1_.id as id1_1_, repository2_.id as id9_2_, project3_.id as id6_3_, user4_.id as id7_4_, changeset0_.author_id as author5_2_0_, changeset0_.createDate as createDate2_0_, changeset0_.message as message2_0_, changeset0_.revision as revision2_0_, changeentr1_.changeType as changeType1_1_, changeentr1_.changeset_id as changeset4_1_1_, changeentr1_.diff as diff1_1_, changeentr1_.repositoryEntity_id as reposito5_1_1_, changeentr1_.repositoryEntityVersion_id as reposito6_1_1_, changeentr1_.sourceChangeEntry_id as sourceCh7_1_1_, changeentr1_.changeset_id as changeset4_0__, changeentr1_.id as id0__, repository2_.project_id as connecti6_9_2_, repository2_.name as name9_2_, repository2_.parent_id as parent7_9_2_, repository2_.path as path9_2_, repository2_.state as state9_2_, repository2_.type as type9_2_, project3_.projectName as connecti2_6_3_, project3_.driverName as driverName6_3_, project3_.isAnonymous as isAnonym4_6_3_, project3_.lastUpdatedRevision as lastUpda5_6_3_, project3_.password as password6_3_, project3_.url as url6_3_, project3_.username as username6_3_, user4_.username as username7_4_, user4_.email as email7_4_, user4_.name as name7_4_, user4_.password as password7_4_, user4_.principles as principles7_4_, user4_.userType as userType7_4_ from Changeset changeset0_ inner join ChangeEntry changeentr1_ on changeset0_.id=changeentr1_.changeset_id inner join RepositoryEntity repository2_ on changeentr1_.repositoryEntity_id=repository2_.id inner join project project3_ on repository2_.project_id=project3_.id inner join users user4_ on changeset0_.author_id=user4_.id where project3_.id=? order by changeset0_.revision desc Hibernate: select repository0_.id as id10_9_, repository0_.changeEntry_id as changeEn2_10_9_, repository0_.repositoryEntity_id as reposito3_10_9_, changeentr1_.id as id1_0_, changeentr1_.changeType as changeType1_0_, changeentr1_.changeset_id as changeset4_1_0_, changeentr1_.diff as diff1_0_, changeentr1_.repositoryEntity_id as reposito5_1_0_, changeentr1_.repositoryEntityVersion_id as reposito6_1_0_, changeentr1_.sourceChangeEntry_id as sourceCh7_1_0_, changeset2_.id as id2_1_, changeset2_.author_id as author5_2_1_, changeset2_.createDate as createDate2_1_, changeset2_.message as message2_1_, changeset2_.revision as revision2_1_, user3_.id as id7_2_, user3_.username as username7_2_, user3_.email as email7_2_, user3_.name as name7_2_, user3_.password as password7_2_, user3_.principles as principles7_2_, user3_.userType as userType7_2_, repository4_.id as id9_3_, repository4_.project_id as connecti6_9_3_, repository4_.name as name9_3_, repository4_.parent_id as parent7_9_3_, repository4_.path as path9_3_, repository4_.state as state9_3_, repository4_.type as type9_3_, project5_.id as id6_4_, project5_.projectName as connecti2_6_4_, project5_.driverName as driverName6_4_, project5_.isAnonymous as isAnonym4_6_4_, project5_.lastUpdatedRevision as lastUpda5_6_4_, project5_.password as password6_4_, project5_.url as url6_4_, project5_.username as username6_4_, repository6_.id as id9_5_, repository6_.project_id as connecti6_9_5_, repository6_.name as name9_5_, repository6_.parent_id as parent7_9_5_, repository6_.path as path9_5_, repository6_.state as state9_5_, repository6_.type as type9_5_, repository7_.id as id10_6_, repository7_.changeEntry_id as changeEn2_10_6_, repository7_.repositoryEntity_id as reposito3_10_6_, repository8_.id as id9_7_, repository8_.project_id as connecti6_9_7_, repository8_.name as name9_7_, repository8_.parent_id as parent7_9_7_, repository8_.path as path9_7_, repository8_.state as state9_7_, repository8_.type as type9_7_, changeentr9_.id as id1_8_, changeentr9_.changeType as changeType1_8_, changeentr9_.changeset_id as changeset4_1_8_, changeentr9_.diff as diff1_8_, changeentr9_.repositoryEntity_id as reposito5_1_8_, changeentr9_.repositoryEntityVersion_id as reposito6_1_8_, changeentr9_.sourceChangeEntry_id as sourceCh7_1_8_ from RepositoryEntityVersion repository0_ left outer join ChangeEntry changeentr1_ on repository0_.changeEntry_id=changeentr1_.id left outer join Changeset changeset2_ on changeentr1_.changeset_id=changeset2_.id left outer join users user3_ on changeset2_.author_id=user3_.id left outer join RepositoryEntity repository4_ on changeentr1_.repositoryEntity_id=repository4_.id left outer join project project5_ on repository4_.project_id=project5_.id left outer join RepositoryEntity repository6_ on repository4_.parent_id=repository6_.id left outer join RepositoryEntityVersion repository7_ on changeentr1_.repositoryEntityVersion_id=repository7_.id left outer join RepositoryEntity repository8_ on repository7_.repositoryEntity_id=repository8_.id left outer join ChangeEntry changeentr9_ on changeentr1_.sourceChangeEntry_id=changeentr9_.id where repository0_.id=? The 2nd one is repeated many times - for a result set of 17 objects, the 2nd statement executed 521 times. I suspect this is as a result of the parent/child relationship in the RepositoryEntity object. For the purposes of this select, I actually only require the parent object fetched. Any suggestions?

• My app crashes after multiple rotates

  - by Ian Rae

  My app is crashing when I try and rotate it more than a couple of times. I first thought it was just the iPhone Simulator, so I loaded the app onto an iPod touch, and it crashed after fewer rotates in a row. I suspect it's a memory leak in one of my rotate methods. The only place I can think that the crash is being caused is in willRotateToInterfaceOrientation:duration:. The only two methods related to rotate that I've added/extended are shouldAutorotateToInterfaceOrientation: and willRotateToInterfaceOrientation:duration and I don't think it's the first because it only contains the two words: return YES;. Here is my willRotateToInterfaceOrientation:duration: method so you can review it and see where the possible memory leak is. -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)orientation duration:(NSTimeInterval)duration { UIFont *theFont; if ((orientation == UIInterfaceOrientationLandscapeLeft) || (orientation == UIInterfaceOrientationLandscapeRight)) { theFont = [yearByYear.font fontWithSize:16.0]; yearByYear.font = theFont; [theview setContentSize:CGSizeMake(460.0f, 635.0f)]; } else { theFont = [yearByYear.font fontWithSize:10.0]; yearByYear.font = theFont; [theview setContentSize:CGSizeMake(300.0f, 460.0f)]; } [theFont release]; } yearByYear is a UITextView theview is a UIScrollView if anyone has any idea of why my app is crashing, I would be greatly appreciative.
