• xpath/xslt to determine index of context node relative to all nodes of same name?

  - by Geoff

  Given the schema below - with a "query" node as the context, is it possible with xpath/xslt to determine the index of that "query" node relative to all "query" nodes in the document (not position() relative to its immediate siblings).

• What do you call a set of Javascript closures that share a common context?

  - by Ed Stauff

  I've been trying to learn closures (in Javascript), which kind of hurts my brain after way too many years with C# and C++. I think I now have a basic understanding, but one thing bothers me: I've visited lots of websites in this Quest for Knowledge, and nowhere have I seen a word (or even a simple two-word phrase) that means "a set of Javascript closures that share a common execution context". For example: function CreateThingy (name, initialValue) { var myName = name; var myValue = initialValue; var retObj = new Object; retObj.getName = function() { return myName; } retObj.getValue = function() { return myValue; } retObj.setValue = function(newValue) { myValue = newValue; } return retObj; }; From what I've read, this seems to be one common way of implementing data hiding. The value returned by CreateThingy is, of course, an object, but what would you call the set of functions which are properties of that object? Each one is a closure, but I'd like a name I can used to describe (and think about) all of them together as one conceptual entity, and I'd rather use a commonly accepted name than make one up. Thanks! -- Ed

• Helicon ISAPI Rewrite Proxy 500 Internal Server Error

  - by Rob Stevenson-Leggett

  Hi, I have a website running at www.domain.com. The client now wants the website to appear to be running under www.otherdomain.com/whatson/brand/ Since the website is umbraco it won't run under a subfolder. I wanted to use ISAPI rewrite to proxy requests to www.domain.com using the following rule in a .htaccess at www.otherdomain.com/whatson/brand/ RewriteRule ^(.*)$ http://www.domain.com/$1 [P,L] However, when I apply this I get an ugly 500 Internal Server Error. There's nothing in the event log. So I turned on ISAPI logging and can see the following 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) init rewrite engine with requested uri /whatson/brand/home.aspx Then it testing all the other rewrite rules on the server. Then this 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (1) Htaccess process request w:\websites\otherdomain.com\docs2\whatson\brand\.htaccess 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (3) applying pattern '^(.*)$' to uri 'home.aspx' 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) forcing proxy-throughput with http://www.domain.com/home.aspx 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (1) go-ahead with proxy request http://www.domain.com/home.aspx [OK] 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) rewrite 'home.aspx' -> '/whatson/brand/home.aspxx.rwhlp?p=0' 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) internal redirect with /whatson/brand/home.aspxx.rwhlp?p=0 [INTERNAL REDIRECT] So it appears to work according to the logs, but I'm not seeing the page come through.. It's worth noting that www.domain.com and www.otherdomain.com are on the same box. LogLevel is 3 and RewriteLogLevel is 3 (I've tried with 9 and debug but there is too much traffic going through the other sites on the box) Any ideas?

• where Redirect permanent rule need to be add

  - by eli1128

  I want redirect my web site http request to https my web site is https://test my apache is version 2.4 and ssl configration is (ssl.conf) on separate file from httpd.conf and I am not using .htaccess file so where I should append. i have tried on both file but didn't work. Redirect permanent / https://test is that should be on my httpd.conf or ssl.conf or did I miss something else. I prefer to use redirect over rewrite.

• Data Source Connection Pool Sizing

  - by Steve Felts

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} One of the most time-consuming procedures of a database application is establishing a connection. The connection pooling of the data source can be used to minimize this overhead.  That argues for using the data source instead of accessing the database driver directly. Configuring the size of the pool in the data source is somewhere between an art and science – this article will try to move it closer to science.  From the beginning, WLS data source has had an initial capacity and a maximum capacity configuration values.  When the system starts up and when it shrinks, initial capacity is used.  The pool can grow to maximum capacity.  Customers found that they might want to set the initial capacity to 0 (more on that later) but didn’t want the pool to shrink to 0.  In WLS 10.3.6, we added minimum capacity to specify the lower limit to which a pool will shrink.  If minimum capacity is not set, it defaults to the initial capacity for upward compatibility.   We also did some work on the shrinking in release 10.3.4 to reduce thrashing; the algorithm that used to shrink to the maximum of the currently used connections or the initial capacity (basically the unused connections were all released) was changed to shrink by half of the unused connections. The simple approach to sizing the pool is to set the initial/minimum capacity to the maximum capacity.  Doing this creates all connections at startup, avoiding creating connections on demand and the pool is stable.  However, there are a number of reasons not to take this simple approach. When WLS is booted, the deployment of the data source includes synchronously creating the connections.  The more connections that are configured in initial capacity, the longer the boot time for WLS (there have been several projects for parallel boot in WLS but none that are available).  Related to creating a lot of connections at boot time is the problem of logon storms (the database gets too much work at one time).   WLS has a solution for that by setting the login delay seconds on the pool but that also increases the boot time. There are a number of cases where it is desirable to set the initial capacity to 0.  By doing that, the overhead of creating connections is deferred out of the boot and the database doesn’t need to be available.  An application may not want WLS to automatically connect to the database until it is actually needed, such as for some code/warm failover configurations. There are a number of cases where minimum capacity should be less than maximum capacity.  Connections are generally expensive to keep around.  They cause state to be kept on both the client and the server, and the state on the backend may be heavy (for example, a process).  Depending on the vendor, connection usage may cost money.  If work load is not constant, then database connections can be freed up by shrinking the pool when connections are not in use.  When using Active GridLink, connections can be created as needed according to runtime load balancing (RLB) percentages instead of by connection load balancing (CLB) during data source deployment. Shrinking is an effective technique for clearing the pool when connections are not in use.  In addition to the obvious reason that there times where the workload is lighter,  there are some configurations where the database and/or firewall conspire to make long-unused or too-old connections no longer viable.  There are also some data source features where the connection has state and cannot be used again unless the state matches the request.  Examples of this are identity based pooling where the connection has a particular owner and XA affinity where the connection is associated with a particular RAC node.  At this point, WLS does not re-purpose (discard/replace) connections and shrinking is a way to get rid of the unused existing connection and get a new one with the correct state when needed. So far, the discussion has focused on the relationship of initial, minimum, and maximum capacity.  Computing the maximum size requires some knowledge about the application and the current number of simultaneously active users, web sessions, batch programs, or whatever access patterns are common.  The applications should be written to only reserve and close connections as needed but multiple statements, if needed, should be done in one reservation (don’t get/close more often than necessary).  This means that the size of the pool is likely to be significantly smaller then the number of users.   If possible, you can pick a size and see how it performs under simulated or real load.  There is a high-water mark statistic (ActiveConnectionsHighCount) that tracks the maximum connections concurrently used.  In general, you want the size to be big enough so that you never run out of connections but no bigger.   It will need to deal with spikes in usage, which is where shrinking after the spike is important.  Of course, the database capacity also has a big influence on the decision since it’s important not to overload the database machine.  Planning also needs to happen if you are running in a Multi-Data Source or Active GridLink configuration and expect that the remaining nodes will take over the connections when one of the nodes in the cluster goes down.  For XA affinity, additional headroom is also recommended.  In summary, setting initial and maximum capacity to be the same may be simple but there are many other factors that may be important in making the decision about sizing.

• Starting ActiveMQ message listener in Tomcat?

  - by Nick Swarr

  I've created an ActiveMQ MessageListener and configured it using Spring. I'm hosting the listener in Tomcat. When I start up the web application (that features only the listener), should the listener automatically start? Or do I need additional configuration? Here's what I have. First, updated the web.xml to allow spring to configure itself on startup, <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/spring/applicationContext.xml</param-value> </context-param> </web-app> Then I created the applicationContext.xml to configure the ActiveMQ listener, <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.somepackage"/> <context:property-placeholder location="classpath:env.properties"/> <bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://localhost:61616" /> </bean> <bean id="documentListener" class="com.somepackage.SomeListener" /> <bean id="container" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="cachingConnectionFactory"/> <property name="messageListener" ref="documentListener"/> <property name="destinationName" value="STOCKS.MSFT" /> </bean> <bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="jmsFactory" /> <property name="sessionCacheSize" value="1" /> </bean> </beans> And that's it. Based on what I've seen around the web, I can't tell if that's all I need? Maybe I need some other configuration in Tomcat to kick off the listener?

• How to load a springframework ApplicationContext from Jython

  - by staticman

  I have a class that loads a springframework application context like so: package com.offlinesupport; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class OfflineScriptSupport { private static ApplicationContext appCtx; public static final void initialize() { appCtx = new ClassPathXmlApplicationContext( new String[] { "mycontext.spring.xml" } ); } public static final ApplicationContext getApplicationContext() { return appCtx; } public static final void main( String[] args ) { System.out.println( "Starting..." ); initialize(); System.out.println( "loaded" ); } } The class OfflineScriptSupport, and the file mycontext.spring.xml are each deployed into separate jars (along with other classes and resources in their respective modules). Lets say the jar files are OfflineScriptSupport.jar and *MyContext.jar". mycontext.spring.xml is put at the root of the jar. In a Jython script (*myscript.jy"), I try to call the initialize method to create the application context: from com.offlinesupport import OfflineScriptSupport OfflineScriptSupport.initialize(); I execute the Jython script with the following command (from Linux): jython -Dpython.path=spring.jar:OfflineScriptSupport.jar:MyContext.jar myscript.jy The Springframework application context cannot find the mycontext.spring.xml file. It displays the following error: java.io.FileNotFoundException: class path resource [mycontext.spring.xml] cannot be opened because it does not exist at org.springframework.core.io.ClassPathResource.getInputStream(ClassPathResource.java:137) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:167) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:148) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:126) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java:142) at org.springframework.context.support.AbstractXmlApplicationContext.loadBeanDefinitions(AbstractXmlApplicationContext.java:113) at org.springframework.context.support.AbstractXmlApplicationContext.loadBeanDefinitions(AbstractXmlApplicationContext.java:81) at org.springframework.context.support.AbstractRefreshableApplicationContext.refreshBeanFactory(AbstractRefreshableApplicationContext.java:89) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:269) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:87) at org.springframework.context.support.ClassPathXmlApplicationContext.<init>(ClassPathXmlApplicationContext.java:72) at com.offlinesupport.OfflineScriptSupport.initialize(OfflineScriptSupport.java:27) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) If I run the jar directly from Java (using the main entry point in OfflineScriptSupport) it works and there is no error thrown. Is there something special about the way Jython handles classpaths making the Springframework's ClassPathXmlApplicationContext not work (i.e. not be able to find resource files in the classpath)?

• BroadcastReciever doesn't show SMS not Send or Not delivered

  - by user1657111

  While using broadcastreciver for checking sms status, it shows the toast when sms is sent but shows nothing when sms is not sent or delivered (im testing it by putting an abrupt number). the code im using is the one ive seen the most on every site of checking sms delivery status. But my code is only showing the status when sms is sent successfully. Can any one get a hint of what am i doing wrong ? I hav this method in doInBackground() and so obviously im using AsyncTask.

• Using HTML5 Today part 3&ndash; Using Polyfills

  - by Steve Albers

  Shims helps when adding semantic tags to older IE browsers, but there is a huge range of other new HTML5 features that having varying support on browsers.  Polyfills are JavaScript code and/or browser plug-ins that can provide older or less featured browsers with API support.  The best polyfills will detect the whether the current browser has native support, and only adds the functionality if necessary.  The Douglas Crockford JSON2.js library is an example of this approach: if the browser already supports the JSON object, nothing changes.  If JSON is not available, the library adds a JSON property in the global object. This approach provides some big benefits: It lets you add great new HTML5 features to your web sites sooner. It lets the developer focus on writing to the up-and-coming standard rather than proprietary APIs. Where most one-off legacy code fixes tends to break down over time, well done polyfills will stop executing over time (as customer browsers natively support the feature) meaning polyfill code may not need to be tested against new browsers since they will execute the native methods instead. Your should also remember that Polyfills represent an entirely separate code path (and sometimes plug-in) that requires testing for support.  Also Polyfills tend to run on older browsers, which often have slower JavaScript performance.  As a result you might find that performance on older browsers is not comparable. When looking for Polyfills you can start by checking the Modernizr GitHub wiki or the HTML5 Please site. For an example of a polyfill consider a page that writes a few geometric shapes on a <canvas> <script src="jquery-1.7.1.min.js"><script> <script> $(document).ready(function () { drawCanvas(); }); function drawCanvas() { var context = $("canvas")[0].getContext('2d'); //background context.fillStyle = "#8B0000"; context.fillRect(5, 5, 300, 100); // emptybox context.strokeStyle = "#B0C4DE"; context.lineWidth = 4; context.strokeRect(20, 15, 80, 80); // circle context.arc(160, 55, 40, 0, Math.PI * 2, false); context.fillStyle = "#4B0082"; context.fill(); </script>   The result is a simple static canvas with a box & a circle:   …to enable this functionality on a pre-canvas browser we can find a polyfill.  A check on html5please.com references  FlashCanvas.  Pull down the zip and extract the files (flashcanvas.js, flash10canvas.swf, etc) to a directory on your site.  Then based on the documentation you need to add a single line to your original HTML file: <!--[if lt IE 9]><script src="flashcanvas.js"></script><![endif]—> …and you have canvas functionality!  The IE conditional comments ensure that the library is only loaded in browsers where it is useful, improving page load & processing time. Like all Polyfills, you should test to verify the functionality matches your expectations across browsers you need to support.  For instance the Flash Canvas home page advertises 70% support of HTML5 Canvas spec tests.

• how to code multiple button navigation with java activities [migrated]

  - by user1738212

  Question 1: I have 2 activities. I was wondering how to optimize it. I can either create 2 activities with multiple listeners. Or create multiple java files for each button(onclick listener) Question 2: I have tried to create multiple listeners in one java but can only get one button to work. What is the syntax for multiple listeners in one java file? Here is my *updated code: now the issue is no matter what button is clicked on it leads to the same page. package install.fineline; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.widget.Button; import android.view.View; import android.view.View.OnClickListener; public class Activity1 extends Activity2 { Button Button1; Button Button2; Button Button3; Button Button4; Button Button5; Button Button6; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fineline); addListenerOnButton(); } public void addListenerOnButton() { final Context context = this; Button1 = (Button) findViewById(R.id.autobody); Button1.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { Intent intent = new Intent(context, Activity1.class); startActivity(intent); } }); Button2 = (Button) findViewById(R.id.glass); Button2.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Intent intent = new Intent(context, Activity1.class); startActivity(intent); } }); Button3 = (Button) findViewById(R.id.wheels); Button3.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Intent intent = new Intent(context, Activity1.class); startActivity(intent); } }); Button4 = (Button) findViewById(R.id.speedy); Button4.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Intent intent = new Intent(context, Activity1.class); startActivity(intent); } }); Button5 = (Button) findViewById(R.id.sevan); Button5.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Intent intent = new Intent(context, Activity1.class); startActivity(intent); } }); Button6 = (Button) findViewById(R.id.towing); Button6.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { Intent intent = new Intent(context, Activity1.class); startActivity(intent); } }); }} activity2.java package install.fineline; import android.app.Activity; import android.os.Bundle; import android.widget.Button; public class Activity2 extends Activity { Button Button1; public void onCreate1(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.autobody); } Button Button2; public void onCreate2(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.glass); } Button Button3; public void onCreate3(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.wheels); } Button button4; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.speedy); } Button Button5; public void onCreate5(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sevan); } Button Button6; public void onCreate6(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.towing); }}

• django/python: is one view that handles two separate models a good idea?

  - by clime

  I am using django multi-table inheritance: Video and Image are models derived from Media. I have implemented two views: video_list and image_list, which are just proxies to media_list. media_list returns images or videos (based on input parameter model) for a certain object, which can be of type Event, Member, or Crag. It alters its behaviour based on input parameter action, which can be either "edit" or "view". The problem is that I need to ask whether the input parameter model contains Video or Image in media_list so that I can do the right thing. Similar condition is also in helper method media_edit_list that is called from the view. I don't particularly like it but the only alternative I can think of is to have separate logic for video_list and image_list and then probably also separate helper methods for videos and images: video_edit_list, image_edit_list, video_view_list, image_view_list. So four functions instead of just two. That I like even less because the video functions would be very similar to the respective image functions. What do you recommend?

• How to use HTML markup tags inside Bash script

  - by CONtext

  I have crontab and a simple bash script that sends me emails every often containing PHP, NGINX, MYSQL errors from their log files. This is a simplified example. #/home/user/status.sh [email protected] PHP_ERROR=`tail -5 /var/log/php-fpm/error.log` NGINX_ERROR=`tail -5 /var/log/nginx/error.log` MYSQL_ERROR=`tail /var/log/mysqld.log` DISK_SPACE=`df -h` echo " Today's, server report:: ================================== DISK_SPACE: $DISK_SPACE --------------------------------- MEMORY_USAGE: $MEMORY_USAGE ----------------------------------- NGINX ERROR: $NGINX_ERROR ----------------------------------- PHP ERRORS: $PHP_ERROR ------------------------------------ MYSQL_ERRORS: $MYSQL_ERROR ------------------------------------- " | mail -s "Server reports" $EMAIL I know this is a very basic usage, but as you can see, I am trying to separate the errors, but not of the html tags including \n are working. So, my question is, is it possible to use HTML tags to format the text, if not .. then what are the alternatives.

• iPhone SDK 3.2 UIGestureRecognizer interfering with UIView animations?

  - by Brian Cooley

  Are there known issues with gesture recognizers and the UIView class methods for animation? I am having problems with a sequence of animations on a UIImageView from UIGestureRecognizer callback. If the sequence of animations is started from a standard callback like TouchUpInside, the animation works fine. If it is started via the UILongPressGestureRecognizer, then the first animation jumps to the end and the second animation immediately begins. Here's a sample that illustrates my problem. In the .xib for the project, I have a UIImageView that is connected to the viewToMove IBOutlet. I also have a UIButton connected to the startButton IBOutlet, and I have connected its TouchUpInside action to the startButtonClicked IBAction. The TouchUpInside action works as I want it to, but the longPressGestureRecognizer skips to the end of the first animation after about half a second. When I NSLog the second animation (animateTo200) I can see that it is called twice when a long press starts the animation but only once when the button's TouchUpInside action starts the animation. - (void)viewDidLoad { [super viewDidLoad]; UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(startButtonClicked)]; NSArray *recognizerArray = [[NSArray alloc] initWithObjects:longPressRecognizer, nil]; [startButton setGestureRecognizers:recognizerArray]; [longPressRecognizer release]; [recognizerArray release]; } -(IBAction)startButtonClicked { if (viewToMove.center.x < 150) { [self animateTo200:@"Right to left" finished:nil context:nil]; } else { [self animateTo100:@"Right to left" finished:nil context:nil]; } } -(void)animateTo100:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:@"Right to left" context:nil]; [UIView setAnimationDuration:4]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animateTo200:finished:context:)]; viewToMove.center = CGPointMake(100.0, 100.0); [UIView commitAnimations]; } -(void)animateTo200:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:@"Left to right" context:nil]; [UIView setAnimationDuration:4]; viewToMove.center = CGPointMake(200.0, 200.0); [UIView commitAnimations]; }

• Add shadow to UIImage drawn in rounded path

  - by Tom Irving

  I'm drawing a rounded image in a UITableView cell like so: CGRect imageRect = CGRectMake(8, 8, 40, 40); CGFloat radius = 3; CGFloat minx = CGRectGetMinX(imageRect); CGFloat midx = CGRectGetMidX(imageRect); CGFloat maxx = CGRectGetMaxX(imageRect); CGFloat miny = CGRectGetMinY(imageRect); CGFloat midy = CGRectGetMidY(imageRect); CGFloat maxy = CGRectGetMaxY(imageRect); CGContextMoveToPoint(context, minx, midy); CGContextAddArcToPoint(context, minx, miny, midx, miny, radius); CGContextAddArcToPoint(context, maxx, miny, maxx, midy, radius); CGContextAddArcToPoint(context, maxx, maxy, midx, maxy, radius); CGContextAddArcToPoint(context, minx, maxy, minx, midy, radius); CGContextClosePath(context); CGContextClip(context); [self.theImage drawInRect:imageRect]; This looks great, but I'd like to add a shadow to it for added effect. I've tried using something along the lines of: CGContextSetShadowWithColor(context, CGSizeMake(2, 2), 2, [[UIColor grayColor] CGColor]); CGContextFillPath(context); But this only works when the image has transparent areas, if the image isn't transparent at all, it won't even draw a shadow around the border. I'm wondering if there is something I'm doing wrong?

• Preloading multiple comboboxes/listbox itemssource with enumerated values using WCF RIA Services

  - by Dale Halliwell

  I would like to be able to load several RIA entitysets in a single call without chaining/nesting several small LoadOperations together so that they load sequentially. I have several pages that have a number of comboboxes on them. These comboboxes are populated with static values from a database (for example status values). Right now I preload these values in my VM by one method that strings together a series of LoadOperations for each type that I want to load. For example: public void LoadEnums() { context.Load(context.GetMyStatusValues1Query()).Completed += (s, e) => { this.StatusValues1 = context.StatusValues1; context.Load(context.GetMyStatusValues2()).Completed += (s1, e1) => { this.StatusValues2 = context.StatusValues2; context.Load(context.GetMyStatusValues3Query()).Completed += (s2, e2) => { this.StatusValues3 = context.StatusValues3; (....and so on) }; }; }; }; While this works fine, it seems a bit nasty. Also, I would like to know when the last loadoperation completes so that I can load whatever entity I want to work on after this, so that these enumerated values resolve properly in form elements like comboboxes and listboxes. (I think) I can't do this easily above without creating a delegate and calling that on the completion of the last loadoperation. So my question is: does anyone out there know a better pattern to use, ideally where I can load all my static entitysets in a single LoadOperation?

• Drawing a PDF Right-Side-Up in CGContext

  - by Carter Allen

  I'm overriding the drawRect: method in a custom UIView, and I'm doing some custom drawing. All was going well, until I needed to draw a PDF resource (a vector glyph, to be precise) into the context. First I retrieve the PDF from a file: NSURL *pdfURL = [NSURL fileURLWithPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"CardKit.bundle/A.pdf"]]; CGPDFDocumentRef pdfDoc = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL); CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfDoc, 1); Then I create a box with the same dimensions as the loaded PDF: CGRect box = CGPDFPageGetBoxRect(pdfPage, kCGPDFArtBox); Then I save my graphics state, so that I don't screw anything up: CGContextSaveGState(context); And then I perform a scale+translate of the CTM, theoretically flipping the whole context: CGContextScaleCTM(context, 1.0, -1.0); CGContextTranslateCTM(context, 0.0, rect.size.height); I then scale the PDF so that it fits into the view properly: CGContextScaleCTM(context, rect.size.width/box.size.width, rect.size.height/box.size.height); And finally, I draw the PDF and restore the graphics state: CGContextDrawPDFPage(context, pdfPage); CGContextRestoreGState(context); The issue is that there is nothing visible drawn. All this code should theoretically draw the PDF glyph into the view, right? If I remove the scale+translate used to flip the context, it draws perfectly: it just draws upside-down. Any ideas?
