• DOM: element created with cloneNode(true) missing element when added to DOM

  - by user149327

  I'm creating a tree control and I'm attempting to use a parent element as a template for its children. To this end I'm using the element.cloneNode(true) method to deep clone the parent element. However when I insert the cloned element into the DOM it is missing certain inner elements despite having an outerHTML value identical to its parent. Surprisingly I observe the same behavior is in IE, Firefox, and Chrome leading me to believe that it is by design. This is the HTML for the node I'm attempting to clone. <SPAN class=node><A class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf> <IMG class=nodeIcon alt="Taylor Swift" src="images/node.png"><SPAN class=nodeText>Taylor Swift</SPAN></A><SPAN class=nodeDescription>Taylor Swift is a swell gall who is realy great.</SPAN></SPAN> Once I've cloned the node using cloneNode(true) I examine the outerHTML property and find that it is indeed identical to the original. <SPAN class=node><A class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf><IMG class=nodeIcon alt="Taylor Swift" src="images/node.png"><SPAN class=nodeText>Taylor Swift</SPAN></A><SPAN class=nodeDescription>Taylor Swift is a swell gall who is realy great.</SPAN></SPAN> However when I insert it into the DOM and inspect the result using FireBug I find that the element has been transformed: <span class="node" style="top: 0px; left: 0px;"<a class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf>Taylor Swift</a><span class="nodeDescription">It's great</span></span> Notice that the grandchildren of the node (the image tag and the span tag surrounding "Taylor Swift") are missing, although strangely the great grandchild "Taylor Swift" text node has made it into the tree. Can anyone shed some light on this behavior? Why would nodes disappear after insertion into the DOM, and why am I seeing the same result in all three major browser engines?

• C# - NetUseAdd from NetApi32.dll on Windows Server 2008 and IIS7

  - by Jack Ryan

  I am attemping to use NetUseAdd to add a share that is needed by an application. My code looks like this. [DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)] internal static extern uint NetUseAdd( string UncServerName, uint Level, IntPtr Buf, out uint ParmError); ... USE_INFO_2 info = new USE_INFO_2(); info.ui2_local = null; info.ui2_asg_type = 0xFFFFFFFF; info.ui2_remote = remoteUNC; info.ui2_username = username; info.ui2_password = Marshal.StringToHGlobalAuto(password); info.ui2_domainname = domainName; IntPtr buf = Marshal.AllocHGlobal(Marshal.SizeOf(info)); try { Marshal.StructureToPtr(info, buf, true); uint paramErrorIndex; uint returnCode = NetUseAdd(null, 2, buf, out paramErrorIndex); if (returnCode != 0) { throw new Win32Exception((int)returnCode); } } finally { Marshal.FreeHGlobal(buf); } This works fine on our server 2003 boxes. But in attempting to move over to Server 2008 and IIS7 this doesnt work any more. Through liberal logging i have found that it hangs on the line Marshal.StructureToPtr(info, buf, true); I have absolutely no idea why this is can anyone shed any light on it for tell me where i might look for more information?

• C# Process Exited event not firing from within webservice

  - by davidpizon

  I am attempting to wrap a 3rd party command line application within a web service. If I run the following code from within a console application: Process process= new System.Diagnostics.Process(); process.StartInfo.FileName = "some_executable.exe"; // Do not spawn a window for this process process.StartInfo.CreateNoWindow = true; process.StartInfo.ErrorDialog = false; // Redirect input, output, and error streams process.StartInfo.UseShellExecute = false; process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; process.StartInfo.RedirectStandardInput = true; process.EnableRaisingEvents = true; process.ErrorDataReceived += (sendingProcess, eventArgs) => { // Make note of the error message if (!String.IsNullOrEmpty(eventArgs.Data)) if (this.WarningMessageEvent != null) this.WarningMessageEvent(this, new MessageEventArgs(eventArgs.Data)); }; process.OutputDataReceived += (sendingProcess, eventArgs) => { // Make note of the message if (!String.IsNullOrEmpty(eventArgs.Data)) if (this.DebugMessageEvent != null) this.DebugMessageEvent(this, new MessageEventArgs(eventArgs.Data)); }; process.Exited += (object sender, EventArgs e) => { // Make note of the exit event if (this.DebugMessageEvent != null) this.DebugMessageEvent(this, new MessageEventArgs("The command exited")); }; process.Start(); process.StandardInput.Close(); process.BeginOutputReadLine(); process.BeginErrorReadLine(); process.WaitForExit(); int exitCode = process.ExitCode; process.Close(); process.Dispose(); if (this.DebugMessageEvent != null) this.DebugMessageEvent(this, new MessageEventArgs("The command exited with code: " + exitCode)); All events, including the "process.Exited" event fires as expected. However, when this code is invoked from within a web service method, all events EXCEPT the "process.Exited" event fire. The execution appears to hang at the line: process.WaitForExit(); Would anyone be able to shed some light as to what I might be missing?

• codeigniter & cjax framework, fatal error class 'CI_Controller' not found

  - by Martin

  I'm having this weird error with Codeigniter 2.1.3 and latest cjax for codeigniter. Weird thing is, when I download the latest codeigniter, and latest cjax framework for codeitniger and copy to my friends server, and call: domain.com/ajax.php?test/test2 to show the test ajax examples ... it works like a breeze, but when I do this on my server, I get server error (even tho, we both have same php version and such). Server then throws in error log file this error: PHP Fatal error: Class 'CI_Controller' not found in /hosting/www/domain.com/www/application/response/test.php on line 3 Now, I've read thru stackoverflow with people having this problem and solving by changing the construct and calling CI_Controller instead of Controller. But I already do that ... - I mean it's in the basic example that is suppose to work without touching the code, and it does, just not on my domain for some crappy reason. Ajax.php from cjax framework for codeingter should load controller from folder response, named test and call function test2, which looks like this (the actual file named test.php): class Test extends CI_Controller { function __construct() { parent::__construct(); } /** * * ajax.php?test/test/a/b/c * * @param unknown_type $a * @param unknown_type $b * @param unknown_type $c */ function test($a = null,$b = null, $c = null) { $this->load->view('test', array('data' => $a .' '.$b.' '.$c)); } /** * ajax.php?test/test2 * * Here we are testing out the javascript library. * * Note: the library it is not meant to be included in ajax controllers - but in front-controllers, * it is being used here for the sake of simplicity in testing. */ function test2() { $ajax = ajax(); $ajax->update('response','Cjax Works'); $ajax->append('#response','<br /><br />version: '.$ajax->version); $ajax->success('Cjax was successfully installed.', 5); //see application/views/test2.php $this->load->view('test2'); } I was hoping someone could bring some light into this problem - or maybe someone has already experienced it? Thanks for your time! Mart

• How to assign RelayCommand to Click or SelectedIndexChanges events?

  - by Hikari

  Hello, I'm just starting with MVVM light, but so far it allowed me to solve some of my issues. Infortunately I'm struggling with relatively sime issues in Silverlight. Let's assume the following button with EventToCommand: <i:Interaction.Triggers> <i:EventTrigger EventName="MouseEnter"> <GalaSoft_MvvmLight_Command:EventToCommand Command="{Binding UpdateAccountsCommand, Mode=OneWay}" CommandParameter="{Binding SelectedIndex, ElementName=lstLedgers}"/> </i:EventTrigger> </i:Interaction.Triggers> </Button> How to assign this code to SelectedIndexChanged event? Futher issue - how to assign a command in C# code? The problem is as follows: I'm developing Windows Phone 7 app. Application Bar needs to be initiated in C# (as far as I know there is no xaml code for application bar at this stage). As a result I have no idea how to bind a command to a application bat button in from c#, now xaml. Thanks in advance your your help.

• Writing an efficient cron job script utilizing Zend_Mail_Storage_Imap.

  - by fireeyedboy

  I'm new to the IMAP protocol and Zend_Mail_Storage and I'm writing a small php script for a cron job that should regularly poll an IMAP account and check for new messages, and send an e-mail if new messages have arrived. As you can imagine, I want to only poll the IMAP account for relevant messages, and I only want to send a new e-mail if new messages have arrived since the last polled new message. So I thought of keeping track of the last message I polled with some unique identifier for a message. But I'm a bit uncertain about whether the methods I want to utilize for this do what I expect them to do though. So my questions are: Does the iterator position of Zend_Mail_Storage_Imap actually resemble some IMAP unique identifier for messages, or is it simply only and internal position of Zend_Mail_Storage_Abstract? For instance, if I tell it to seek() to message 5 (which I stored from an earlier session) will it indeed seek to the appropriate message on the IMAP server, even if for instance messages have been deleted since last session? Would keeping track of this latest polled message id in a file suffice for a cron job that, say, polls the account every 5 or 10 minutes? Or is this too naive, and should I be using a database for instance. Or is there maybe a much easier way to keep track of such state with Zend_Mail_Storage_Abstract? Also, do I need to poll every IMAP folder? Or is everything accumulated when I poll INBOX? If you could shed some light on any of these matters, I'ld appreciate it. Thanks in advance.

• Best practice: git, github, lighthouse and 2 developers

  - by Alxandr

  I'm setting up a new project and plan on using git and github for sourcecontroll and hosting of repo and lighthouse for bugtracking. I've been working with git for some while now, but only been using it for more of a backup solution than collaborate coding solution. Also, I've noticed that in github you can setup a servicehook to lighthouse so that whenever you push to github it notifies lighthouse of the changes. This uses a token for user-authentication and has the ability to change tickets to resolved etc. However, this token I believe functions that way so that whenever a user pushes to the repo (dosn't matter who), it's the owner of the repo that "updates" to lighthouse. This is a problem. So, I believe it is necessary with 2 separate repos at github (one for each dev), and I'm wondering about the workflow that should be used. Any1 care to shred any light on this matter? Like when to pull and push (and where), and how to make the two github repos in sync or something like that? Or another solution to the problem altogether.

• Repository pattern with lazying loading using POCO

  - by Simon G

  Hi, I'm in the process of starting a new project and creating the business objects and data access etc. I'm just using plain old clr objects rather than any orms. I've created two class libraries: 1) Business Objects - holds all my business objects, all this objects are light weight with only properties and business rules. 2) Repository - this is for all my data access. The majority of my objects will have child list in and my question is what is the best way to lazy load these values as I don't want to bring back unnecessary information if I dont need to. I've thought about when using the "get" on the child property to check if its "null" and if it is call my repository to get the child information. This has two problems from what I can see: 1) The object "knows" how to get itself I would rather no data access logic be held in the object. 2) This required both classes to reference each other which in visual studio throws a circular dependency error. Does anyone have any suggestions on how to overcome this issue or any recommendations on my projects layout and where it can be improved? Thanks

• Ruby on rails generates tests for you. Do those give a false sense of a safety net?

  - by Hamish Grubijan

  Disclaimer: I have not used RoR, and I have not generated tests. But, I will still dare to post this question. Quality Assurance is theoretically impossible to get 100% right in general (Undecidable problem ;), and it is hard in practice. So many developers do not understand that writing good automated tests is an art, and it is hard. When I hear that RoR generates the tests for you, I get very skeptical. It cannot be that easy. Testing is a general concept; it applies across languages. So does the concept of code contracts, it is similar for languages that support it. Code contracts do not generate themselves. The programmer must add the requirements and the promises manually, after doing some thinking about the algorithm / function. If a human gets it wrong, then the tools will propagate the error. Similarly with testing - it takes human judgement about what should happen. Tests do not write themselves, and we are far from the day when a business analyst can just have a conversation with a computer and tell it informally what the requirements are and have the computer do all the work. There is no magic ... how can RoR generate good tests for you? Please shed some light on this. Opinions are ok, for this is a community wiki. Thanks!

• Hibernate: "Field 'id' doesn't have a default value"

  - by André Neves

  Hi, all. I'm facing what I think is a simple problem with Hibernate, but can't get over it (Hibernate forums being unreachable certainly doesn't help). I have a simple class I'd like to persist, but keep getting: SEVERE: Field 'id' doesn't have a default value Exception in thread "main" org.hibernate.exception.GenericJDBCException: could not insert: [hibtest.model.Mensagem] at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103) at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91) [ a bunch more ] Caused by: java.sql.SQLException: Field 'id' doesn't have a default value [ a bunch more ] The relevant code for the persisted class is: package hibtest.model; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Inheritance; import javax.persistence.InheritanceType; @Entity @Inheritance(strategy = InheritanceType.JOINED) public class Mensagem { protected Long id; protected Mensagem() { } @Id @GeneratedValue public Long getId() { return id; } public Mensagem setId(Long id) { this.id = id; return this; } } And the actual running code is just plain: SessionFactory factory = new AnnotationConfiguration() .configure() .buildSessionFactory(); { Session session = factory.openSession(); Transaction tx = session.beginTransaction(); Mensagem msg = new Mensagem("YARR!"); session.save(msg); tx.commit(); session.close(); } I tried some "strategies" within the GeneratedValue annotation but it just doesn't seem to work. Initializing id doesn't help either! (eg Long id = 20L). Could anyone shed some light? EDIT 2: confirmed: messing with@GeneratedValue(strategy = GenerationType.XXX) doesn't solve it SOLVED: recreating the database solved the problem

• Castle Windsor upgrade causes TypeLoadException for generic types

  - by Neil Barnwell

  I have the following mapping in my Castle Windsor xml file which has worked okay (unchanged) for some time: <component id="defaultBasicRepository" service="MyApp.Models.Repositories.IBasicRepository`1, MyApp.Models" type="MyApp.Models.Repositories.Linq.BasicRepository`1, MyApp.Models" lifestyle="perWebRequest"/> I got this from the Windsor documentation at http://www.castleproject.org/container/documentation/v1rc3/usersguide/genericssupport.html. Since I upgraded Windsor, I now get the following exception at runtime: Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.TypeLoadException: GenericArguments[0], 'T', on 'MyApp.Models.Repositories.Linq.BasicRepository`1[TEntity]' violates the constraint of type parameter 'TEntity'. Source Error: Line 44: public static void ConfigureIoC() Line 45: { Line 46: var windsor = new WindsorContainer("Windsor.xml"); Line 47: Line 48: ServiceLocator.SetLocatorProvider(() = new WindsorServiceLocator(windsor)); I'm using ASP.NET MVC 1.0, Visual Studio 2008 and Castle Windsor as downloaded from http://sourceforge.net/projects/castleproject/files/InversionOfControl/2.1/Castle-Windsor-2.1.1.zip/download Can anyone shed any light on this? I'm sure the upgrade of Castle Windsor is what caused it - it's been working well for ages.

• FxCop hates my usage of MVVM

  - by Dave

  I've just started to work with FxCop to see how poorly my code does against its full set of rules. I'm starting off with the "Breaking" rules, and the first one I came across was CA2227, which basically says that you should make a collection property's setter readonly, so that you can't accidentally change the collection data. Since I'm using MVVM, I've found it very convenient to use an ObservableCollection with get/set properties because it makes my GUI updates easy and concise in the code-behind. However, I can also see what FxCop is complaining about. Another situation that I just ran into is with WF, where I need to set the parameters when creating the workflow, and I'd hate to have to write a wrapper class around the collection I'm using just to avoid this particular error message. For example, here's a sample runtime error message that I get when I make properties readonly: The activity 'MyWorkflow' has no public writable property named 'MyCollectionOfStuff' What are you opinions on this? I could either ignore this particular error, but that's probably not good because I could conceivably violate this rule elsewhere in the code where MVVM doesn't apply (model only code, for example). I think I could also change it from a property to a class with methods to manipulate the underlying collection, and then raise the necessary notification from the setter method. I'm a little confused... can anyone shed some light on this?

• Date query with Hibernate on Timestamp Column in PostgreSQL

  - by Shashikant Kore

  A table has timestamp column. A sample value in that could be 2010-03-30 13:42:42. With Hibernate, I am doing a range query Restrictions.between("column-name", fromDate, toDate). The Hibernate mapping for this column is as follows. <property name="orderTimestamp" column="order_timestamp" type="java.util.Date" /> Let's say, I want to find out all the records that have the date 30th March 2010 and 31st March 2010. A range query on this field is done as follows. Date fromDate = new SimpleDateFormat("yyyy-MM-dd").parse("2010-03-30"); Date toDate = new SimpleDateFormat("yyyy-MM-dd").parse("2008-03-31"); Expression.between("orderTimestamp", fromDate, toDate); This doesn't work. The query is converted to respective timestamps as "2010-03-30 00:00:00" and "2010-03-31 00:00:00". So, all the records for the 31st March 2010 are ignored. A simple solution to this problem could be to have the end date as "2010-03-31 23:59:59." But, I would like to know if there is way to match only the date part of the timestamp column. Also, is Expression.between() inclusive of both limits? Documentation doesn't throw any light on this.

• Android Camera without Preview

  - by eyurdakul

  I am writing an android 1.5 application which starts just after boot-up. This is a service and should take a picture without preview. This app will log the light density in some areas whatever. I was able to take a picture but the picture was black. After googling like crazy, i came across a bug thread about it. If you don't generate a preview, the image will be black since android camera needs preview to setup exposure and focus. I've created a surfaceview and listener but the onSurfaceCreated event never gets fired. I guess the reason is, the surface is not being created visually. I've also seen some examples of calling the camera statically with MediaStore.CAPTURE_OR_SOMETHING which takes a picture and saves in the desired folder with two lines of code but it doesn't take a picture too. Do i need to use ipc and bindservice to call this function or do you have any suggestion to achieve my goal (taking a picture without preview) and if so, would you give me a small piece of code as example?

• Understanding WordProcessingML tags and avoid unnecessary tags

  - by rithanyalaxmi

  Hi, I am using MS Word API to generate .docx which contains the data fetched from DB, in which i am applying the respective styles, fonts, symbols, etc. If the data fetched from the DB is quite huge, then there is a problem in displaying those data in the .docx file. I found that internally MS Word 2007 will write some content through tags which may not be needed to display the data. Hence i am figuring out what are the necessary MS Word tags needed when converting into a .xml file. So that i can avoid unnecessary tags and build only the respective tags which are needed to display the data. Hence i am planning to write my own .xml with the MS Word tags which are needed, than generating a .XML from .docx file My queries are:- 1) Whether it is right that the MS Word will generate some tags which may not be needed during the conversion of .docx to document.xml? That makes it heavy? If so what are the tags , so that i can avoid them when write by own .xml file. 2) Please send links to understand about the MS Word tags and its advantages, which tags are needed and which are not ? 3) Whether my approach to write a new .xml similar to document.xml (.docx conversion) is worthy one to go forward so that i can build the .xml with the tags i needed , so that i can improve the performance of the data display? Please shed some light into it and thanks in advance.. Thanks, Rithu

• Magento MAGMI: Product attributes (custom options) not showing up in import

  - by Rodgers and Hammertime

  When importing a CSV into Magento with the MAGMI importing tool, I am unable to import Custom Options (as in size: smalee/medium/large). The import manages to put in the basic products, but the Custom Options don't transfer accross. By custom options I mean the fields Title, Input Type, Is Required, Sort Order Title, Price, Price Type, SKU, Sort Order Title, Price, Price Type, SKU, Sort Order Title, Price, Price Type, SKU, Sort Order and so on ... Found in the custom options menu... Even using the example CSV from the MAGMI SourceForge Wiki: sku,name,description,price,Size:drop_down:1 T-Shirt1,T-Shirt,A T-Shirt,5.00,Small|Medium|Large T-Shirt2,T-Shirt2,Another T-Shirt,6.00,XS|S|M|L|XL ...it fails to import the attributes. So i'm simply using MAGMI with the supplied example data from SourceForge on a blank magento product list, and it doesn't transfer properly. Can anyone shed any light on what might be wrong? I am using Magento ver. 1.6.1.0 if that changes anything. Thanks.

• flexible length struct array inside another struct using C

  - by renz

  Hi I am trying to use C to implement a simple struct: 2 boxes, each contains different number of particles; the exact number of particles are passed in main(). I wrote the following code: typedef struct Particle{ float x; float y; float vx; float vy; }Particle; typedef struct Box{ Particle p[]; }Box; void make_box(Box *box, int number_of_particles); int main(){ Box b1, b2; make_box(&b1, 5); //create a box containing 5 particles make_box(&b2, 10); //create a box containing 10 particles } I've tried to implement make_box with the following code void make_box(struct Box *box, int no_of_particles){ Particle po[no_of_particles]; po[0].x = 1; po[1].x = 2; //so on and so forth... box->p = po; } It's always giving me "invalid use of flexible array member". Greatly appreciated if someone can shed some light on this.

• Getting a new session key after Facebook offline_access permission

  - by Richard

  I have a mobile application that I'm using with Facebook connect. I'm having trouble getting an offline_access session key after a user has granted extended permissions. Here's the user flow: User goes to my site for the first time I send them to m.facebook.com/tos.php? and pass my api key and secret The user logs in using Facebook connect Facebook returns them to a page in my site, mysite/login-success.php with an auth_token in the query string On mysite/login-success.php I instantiate the FB api client and check to see if I already have an offline_access session key for them: $facebook = new Facebook($appapikey, $appsecret); If they haven't already provided offline_access FB gives me a temporary session key I need to get offline_access permission from the user so I forward them on to www.facebook.com/connect/prompt_permissions.php? and pass offline_access in the querystring. The user authorizes offline_access and get forwarded to mysite/permissions-success.php The problem I'm having is that after instantiating the API client on permissions-success.php the session key I have is still the temporary session key, not a new offline_access session key. The only way I've found to get the offline_access key is to delete all cookies for the user and then have them login again using Facebook connect. A fairly poor user experience. Can anyone shed some light on how to use the Facebook api to generate a new session key even if one already exists (in my case a temporary session key)?

  I'm in the process of writing a C# wrapper for Dallmeier Common API light (Camera & Surviellance systems) and I've never written a wrapper before, but I have used the Canon EDSDK C# wrapper. So I'm using the Canon wrapper as a guide to writing the Dallmeier wrapper. I'm currently having issues with wrapping a callback. In the API manual it has the following: dlm_connect int(unsigned long uLWindowHandle, const char * strIP, const char* strUser1, const char* strPwd1, const char* strUser2, const char* strPwd2, void (*callback)(void *pParameters, void *pResult, void *pInput), void * pInput) Arguments - ulWindowhandle - handle of the window that is passed to the ViewerSDK to display video and messages there - strUser1/2 - names of the users to log in. If only single user login is used strUser2 is - NULL - strPwd1/2 - passwords of both users. If strUser2 is NULL strPwd2 is ignored. Return This function creates a SessionHandle that has to be passed Callback pParameters will be structured: - unsigned long ulFunctionID - unsigned long ulSocketHandle, //handle to socket of the established connection - unsigned long ulWindowHandle, - int SessionHandle, //session handle of the session created - const char * strIP, - const char* strUser1, - const char* strPwd1, - const char* strUser2, - const char * strPWD2 pResult is a pointer to an integer, representing the result of the operation. Zero on success. Negative values are error codes. So from what I've read on the Net and Stack Overflow - C# uses delegates for the purpose of callbacks. So I create a my Callback function : public delegate uint DallmeierCallback(DallPparameters pParameters, IntPtr pResult, IntPtr pInput); I create the connection function [DllImport("davidapidis.dll")] public extern static int dlm_connect(ulong ulWindowHandle, string strIP, string strUser1, string strPwd1, string strUser2, string strPwd2, DallmeierCallback inDallmeierFunc And (I think) the DallPParameters as a struct : [StructLayout(LayoutKind.Sequential)] public struct DallPParameters { public ulong ulfunctionID; public ulong ulsocketHandle; public ulong ulWindowHandle; ... } All of this is in my wrapper class. Am I heading in the right direction or is this completely wrong?

• iPhone SDK - UITabBarConroller and custom design

  - by Cheryl

  Hi I am having a problem with my tab bars at the bottom of the screen. The designer has decided it should be one colour (not black) when inactive and another colour when active. I have worked out how to replace the main colour of the tabbar by subclassing UITabBarController and doing this:- - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, self.view.bounds.size.height); UIView *v = [[UIView alloc] initWithFrame:frame]; //get percentage values from digitalcolour meter and enter as decimals v.backgroundColor = [UIColor colorWithRed:.0 green:.706 blue:.863 alpha:1]; [tabBar1 insertSubview:v atIndex:0]; [v release]; } I just can't see how to make the active tabbar be a separate colour when it is selected. I have tried subclassing UITabBarItem but there doesn't seem to be any property for me to set to change the background colour of the tab. They also want to have the icons on the tab bar not be blue and grey and I can't figure out how to do that. In the ViewController for one tab bar item I have put this into viewdidload:- myTabBarItem *tabItem = [[myTabBarItem alloc] initWithTitle:@"listOOO" image:[UIImage imageNamed:@"starcopy.png"] tag:1]; tabItem.customHighlightedImage=[UIImage imageNamed:@"starcopy.png"]; self.tabBarItem=tabItem; [tabItem release]; tabItem=nil; and in my subclass of UITabBarItem I have put this:- -(UIImage *) selectedImage{ return self.customHighlightedImage; } Only I don't see the icon at all. If I put this into the viewDidLoad of my subclass of UITabBarController:- for (UITabBarItem *item in tabBar1.items){ item.image = [UIImage imageNamed:@"starcopy.png"]; } Then all my tab bars have the icon but they are blue (and grey when inactive) how would I get them not to become blue but stay their original colour? If you have any light on this problem please help as I have been banking my head on the wall for 2 days now and it's getting me down. Thanks in advance Cheryl

• how to define fill colours in ggplot histogram?

  - by Andreas

  I have the following simple data data <- structure(list(status = c(9, 5, 9, 10, 11, 10, 8, 6, 6, 7, 10, 10, 7, 11, 11, 7, NA, 9, 11, 9, 10, 8, 9, 10, 7, 11, 9, 10, 9, 9, 8, 9, 11, 9, 11, 7, 8, 6, 11, 10, 9, 11, 11, 10, 11, 10, 9, 11, 7, 8, 8, 9, 4, 11, 11, 8, 7, 7, 11, 11, 11, 6, 7, 11, 6, 10, 10, 9, 10, 10, 8, 8, 10, 4, 8, 5, 8, 7), statusgruppe = c(0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 0, 1, 1, 0, NA, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 1, 1, 1, 0, 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0)), .Names = c("status", "statusgruppe"), class = "data.frame", row.names = c(NA, -78L )) from that I'd like to make a histogram: ggplot(data, aes(status))+ geom_histogram(aes(y=..density..), binwidth=1, colour = "black", fill="white")+ theme_bw()+ scale_x_continuous("Staus", breaks=c(min(data$status,na.rm=T), median(data$status, na.rm=T), max(data$status, na.rm=T)),labels=c("Low", "Middle", "High"))+ scale_y_continuous("Percent", formatter="percent") Now - i'd like for the bins to take colou according to value - e.g. bins with value 9 gets dark grey - everything else should be light grey. I have tried with "fill=statusgruppe", scale_fill_grey(breaks=9) etc. - but I can't get it to work. Any ideas?

• Creating an MJPEG Viewer Iphone

  - by Tony

  Hey all, Im trying to make a MJPEG viewer in Objective C but I'm having a bunch of issues with it. First off, Im using AsyncSocket(http://code.google.com/p/cocoaasyncsocket/) which lets me connect to the host. Here's what I got so far NSLog(@"Ready"); asyncSocket = [[AsyncSocket alloc] initWithDelegate:self]; //http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi NSError *err = nil; if(![asyncSocket connectToHost:@"kamera5.vfp.slu.se" onPort:80 error:&err]) { NSLog(@"Error: %@", err); } then in the didConnectToHost method: - (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ NSLog(@"Accepted client %@:%hu", host, port); NSString *urlString = [NSString stringWithFormat:@"http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi"]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"GET"]; //set headers NSString *_host = [NSString stringWithFormat:host]; [request addValue:_host forHTTPHeaderField: @"Host"]; NSString *KeepAlive = [NSString stringWithFormat:@"300"]; [request addValue:KeepAlive forHTTPHeaderField: @"Keep-Alive"]; NSString *connection = [NSString stringWithFormat:@"keep-alive"]; [request addValue:connection forHTTPHeaderField: @"Connection"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"Response Code: %d", [urlResponse statusCode]); if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) { NSLog(@"Response: %@", result); //here you get the response } } This calls the MJPEG stream, but it doesn't call it to get more data. What I think its doing is just loading the first chunk of data, then disconnecting. Am I doing this totally wrong or is there light at the end of this tunnel? Thanks!

• Using ComplexType with ToList causes InvalidOperationException

  - by Chris Paynter

  I have this model namespace ProjectTimer.Models { public class TimerContext : DbContext { public TimerContext() : base("DefaultConnection") { } public DbSet<Project> Projects { get; set; } public DbSet<ProjectTimeSpan> TimeSpans { get; set; } } public class DomainBase { [Key] public int Id { get; set; } } public class Project : DomainBase { public UserProfile User { get; set; } public string Name { get; set; } public string Description { get; set; } public IList<ProjectTimeSpan> TimeSpans { get; set; } } [ComplexType] public class ProjectTimeSpan { public DateTime TimeStart { get; set; } public DateTime TimeEnd { get; set; } public bool Active { get; set; } } } When I try to use this action I get the exception The type 'ProjectTimer.Models.ProjectTimeSpan' has already been configured as an entity type. It cannot be reconfigured as a complex type. public ActionResult Index() { using (var db = new TimerContext()) { return View(db.Projects.ToList); } } The view is using the model @model IList<ProjectTimer.Models.Project> Can any one shine some light as to why this would be happening?

• LaTeX: bibliography per chapter.

  - by YuppieNetworking

  Hello all, I am helping a colleague with his PhD thesis and we need to present the bibliography at the end of each chapter. The question is: does anyone have a minimal working example for this case using latex+bibtex? The current document structure that we use is the following: main.tex chap1.tex chap2.tex ... chapn.tex biblio.bib Where main.tex contains packages, document declarations, macros and \includes for each chapter. biblio.bib is the only bibtex file (I think is easier to have all citations in one place). We have searched and tried with different latex packages, reading and following their documentation. Specifically, bibitems and chapterbib. bibitems successfully generates bu*.aux files, but when running bibtex for each one of them, an error occurs since there is no \bibdata element in the .aux file. chapterbib also generates a .aux file, but bibtex finishes with an error caused by using multiple \bibliography{file} in the .tex files (one per chapter). Some coworkers suggested using a separate bibtex file for each chapter, which could be a problem of maintenance in the future when citing the same publications in different chapters. We will like to continue having this document structure, if possible. So, if anyone could shed some light to this problem, we will appreciate it. Thanks.
