  • Why does my DataTemplate break the WPF designer?

    - by PRINCESS FLUFF
    Why does the DataTemplate line break the WPF designer in Visual Studio 2008? The program compiles and runs properly. The DataTemplate is applied as it should. However the entire DataTemplate block of code is underlined in red, and when I simply "build" the program without running, I get the error "Type reference cannot find public type named 'Character'" How come it can't find it in the designer yet the program applies the template properly? <UserControl x:Class="WPF_Tests.Tests.TwoCollecViews.TwoViews" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:DetailsPane="clr-namespace:WPF_Tests.Tests.DetailsPane" > <UserControl.Resources> <DataTemplate DataType="{x:Type DetailsPane:Character}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Name}"></TextBlock> </StackPanel> </DataTemplate> </UserControl.Resources> <Grid> <ListBox ItemsSource="{Binding Path=Characters}" /> </Grid> </UserControl> EDIT: I am being told that this may be a bug in Visual Studio 2008, as it worked correctly in 2010. You can download the code here: http://www.mediafire.com/?z1myytvwm4n - The Test/TwoCollec xaml file's designer will break with this code.

  • What's a good way to remove all of the subviews of a UIScrollView?

    - by Moshe
    I have a scroll view and I need to reload the contents often while my app is running. Right now, I'm using the following line of code to remove the subviews before adding them back again: [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; Should I be using the following instead? scrollView.subviews = nil; For some reason, the (first) above line of code seems to crash the app every 16 times it is run. Am I leaking memory somewhere? The following method takes an array of views, the scroller (which is a constant) and the direction. Edit: - (void)loadViews:(NSArray *)views IntoScroller:(UIScrollView *)scroller withDirection:(NSString *)direction{ //Set up the scrollView [scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; if([direction isEqualToString:@"horizontal"]){ scrollView.frame = CGRectMake(0, 0, 1024, 768); scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * [[NSNumber numberWithUnsignedInt:[views count]] floatValue], scrollView.frame.size.height); }else if([direction isEqualToString:@"vertical"]){ scrollView.frame = CGRectMake(0, 0, 1024, 768); scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, scrollView.frame.size.height * [[NSNumber numberWithUnsignedInt:[views count]] floatValue]); } for (int i=0; i<[[NSNumber numberWithUnsignedInt:[views count]] intValue]; i++) { [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:scrollView.frame]; if([direction isEqualToString:@"horizontal"]){ [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:CGRectMake(i * [[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view].frame.size.width, 0, scrollView.frame.size.width, scrollView.frame.size.height)];//CGRectMake(i * announcementView.view.frame.size.width, -scrollView.frame.origin.x, scrollView.frame.size.width, scrollView.frame.size.height)]; }else if([direction isEqualToString:@"vertical"]){ [[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view] setFrame:CGRectMake(0, i * [[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view].frame.size.height, scrollView.frame.size.width, scrollView.frame.size.height)]; } [scrollView addSubview:[[views objectAtIndex:[[NSNumber numberWithInt:i] unsignedIntValue]] view]]; } }

  • Binding a date string parameter in an MS Access PDO query

    - by harryg
    I've made a PDO database class which I use to run queries on an MS Access database. When querying using a date condition, as is common in SQL, dates are passed as a string. Access usually expects the date to be surrounded in hashes however. E.g. SELECT transactions.amount FROM transactions WHERE transactions.date = #2013-05-25#; If I where to run this query using PDO I might do the following. //instatiate pdo connection etc... resulting in a $db object $stmt = $db->prepare('SELECT transactions.amount FROM transactions WHERE transactions.date = #:mydate#;'); //prepare the query $stmt->bindValue('mydate', '2013-05-25', PDO::PARAM_STR); //bind the date as a string $stmt->execute(); //run it $result = $stmt->fetch(); //get the results As far as my understanding goes the statement that results from the above would look like this as binding a string results in it being surrounded by quotes: SELECT transactions.amount FROM transactions WHERE transactions.date = #'2013-05-25'#; This causes an error and prevents the statement from running. What's the best way to bind a date string in PDO without causing this error? I'm currently resorting to sprintf-ing the string which I'm sure is bad practise. Edit: if I pass the hash-surrounded date then I still get the error as below: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22018]: Invalid character value for cast specification: -3030 [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression. (SQLExecute[-3030] at ext\pdo_odbc\odbc_stmt.c:254)' in C:\xampp\htdocs\ips\php\classes.php:49 Stack trace: #0 C:\xampp\htdocs\ips\php\classes.php(49): PDOStatement-execute() #1 C:\xampp\htdocs\ips\php\classes.php(52): database-execute() #2 C:\xampp\htdocs\ips\try2.php(12): database-resultset() #3 {main} thrown in C:\xampp\htdocs\ips\php\classes.php on line 49

  • How much business logic belongs in RIA services layer?

    - by jkohlhepp
    I have been experimenting recently with Silverlight, RIA Services, and Entity Framework using .NET 4.0. I'm trying to figure out if that stack makes sense for use in any of my upcoming projects. It certainly seems like these technologies can be very productive for developing applications, but I'm struggling to decide how an application on top of this stack should be architected. The main issue I have is that in most of the demos I've seen most of the business logic ends up as DataAnnotations and custom validations in the RIA Services domain service class. This seems inappropriate to me. I view the domain service as basically a glorified web service that happens to make it easy to push information to the client. But most of what I've seen seems to orient the domain service as the main source of business logic in the application. So, my questions: What is the best location for business logic (rules, validations, behaviors, authorization) in an application using this stack? Are there any guidelines published at an architectural level for using this stack? My questions pertain to large, complex, and long-lived applications. Obviously for an application of only a few screens this is less of a concern. Edit: Another thing I meant to mention is that obviously you can make the domain service class stupid, but then you lose a lot of the automagic entity information (e.g. validations) being pushed to the client. And then if you lose that is there any point to using RIA services?

  • Pushing to bare Git repository (remote) causes it to stop being bare

    - by NSD
    I have a local repository called TestRepo. I clone it with the --bare option, zip this clone up, and throw it on my server. Unzip it, and it's still bare. I then clone the bare remote repository locally over ssh with something like git clone ssh://[email protected]/~/TestRepo.git TestRepoCloned The local TestRepoCloned is not bare and has a remote called "origin." It appears to be tracking correctly from the looks of its config file [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true ignorecase = true [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = ssh://[email protected]/~/TestRepo.git [branch "master"] remote = origin merge = refs/heads/master I edit an existing file. I commit the change to the current branch (master) via git commit -a -m "Edited a file." The commit succeeds and all is well. I decide to push this change to the remote repository via SSH with a git push The remote repository is now no longer bare, but has a complete working directory, and I get continuous error messages on all further attempts to push to it. Everything I've read seems to suggest that what I'm doing is correct, but it simply is not working. How am I supposed to push changes to a bare remote repo and actually keep it bare?

  • JQuery & Wordpress - Hide multiple divs inside unique ID?

    - by steelfrog
    I'm trying to write a short Wordpress JQuery for Wordpress comments that would allow users to toggle specific comments on and off. This is my first script, and I'm having a tough time. Once overtly simplified, the comments are formatted like so: <li id="li-comment-<?php comment_ID() ?>"> <div class="gravatar"><img src="#" /></div> <div class="comment_poster">Username</div> <div class="comment_options">Option buttons</div> <div class="comment_content">Comment</div> </li> In the "comment_options" DIV is a series of buttons that control the individual comments (reply, quote, edit, close, etc.). The close button is what I'm trying to write this script for. I need it to toggle the "gravtar" and "comment_content" DIVs, but leave the rest in place so that it still displays the user ID and controls. However, I can't seem to figure out how to contain the action. This is what I have so far: $(document).ready(function() { $("div.trigger").click(function() { $("div.gravatar").slideToggle(); $("div.comment_content").slideToggle(); }); }); The problem with this is that it closes are the .gravatar and .comment_content on the page, not just the ones found in the same list item. If you're curious, this is the page I'm working on. Any idea how I could resolve this? Again, this is my firs time with JQuery, so I'm a little fuzzy on how it all works. Thanks!

  • Using LINQ to SQL and chained Replace

    - by White Dragon
    I have a need to replace multiple strings with others in a query from p in dx.Table where p.Field.Replace("A", "a").Replace("B", "b").ToLower() = SomeVar select p Which provides a nice single SQL statement with the relevant REPLACE() sql commands. All good :) I need to do this in a few queries around the application... So i'm looking for some help in this regard; that will work as above as a single SQL hit/command on the server It seems from looking around i can't use RegEx as there is no SQL eq Being a LINQ newbie is there a nice way for me to do this? eg is it possible to get it as a IQueryable "var result" say and pass that to a function to add needed .Replace()'s and pass back? Can i get a quick example of how if so? EDIT: This seems to work! does it look like it would be a problem? var data = from p in dx.Videos select p; data = AddReplacements(data, checkMediaItem); theitem = data.FirstOrDefault(); ... public IQueryable<Video> AddReplacements(IQueryable<Video> DataSet, string checkMediaItem) { return DataSet.Where(p => p.Title.Replace(" ", "-").Replace("&", "-").Replace("?", "-") == checkMediaItem); }

  • Image File In Text Editor - What Are The Characters? What's the Process?

    - by TheDarkIn1978
    i'm currently in the process of conceptualizing an art piece for a gallery show next year, so this bizarre question of mine is more than just simple curiosity. if i open up an image file (a .PNG) with Text Edit or Note Pad, the file is presented in textual characters. something like this except: æº"í=™?0Ù:Ã,ÏI8^?K¯pmDHƒÃ?;wÔlD DDF›ä™èÜE[E˜ƒê?¯ƒºäeèçã?'ów+æ1ï‡ê0òHõñ?ò$úîù¥{WÎn}2*Ÿ!y(Ö!%2e9U2µ i4Õ(?=ù(›7}:É?##„G¶VfcVñ[÷D6gvrˆvéZN›=Ù=ó{púp…p?Ók‹oÃvŒÛ»{ùœóüôøW†W–VH\P?P$VTPt^lQ‹_B_S=Q™\Z[Ü)s/{]Œ_û]~¯¿¯Awu˜ùä’JÖ Í*tï[’ÎáÔ=<Æ6?~ZCWSÛpVµ?±ØŒ?nÆ^¨æ??™¡?a¥ë£1µÒÁ#?Gè)G<^mRl™m?jˆj~€"“R–Úª’?u?çO-•m˜â?ìéväˆàˆOä5ùXùûù”]¬]?]›V›œ{X{Óˆ|Ô’Èm{J?4‰Èáæõ}??~Á?óºYáœåüuRFÆ>W|^3Ñ5‰94=,<ú?|1b=2< >ö:?sÃ`¨{úf<f|ÛÖ?ãÊ íâ–âè/_÷O¬}Â?Í›§Ãd’kÃkØ?sSíS? ??øy;-6]ˆ?÷ÌÌÙåËLÈ,l÷uvzNtÆt6Ô6?O ?P?_t_|°N¸]Ÿ{ƒ{è˜3KK> ?x~ò[ñ\ÆXA?x?Ãî?X? ?…°”¸™‘jÂzÕkm~]jObµ·p1°Y‚s?&b”}s?ãËóí-»ñ”÷‰?‡v?ˆ˜WõØ£??æe~;¸n?Ooáa'aÁÎÌ-ª$ª!ª~ ?¨‹CÏpÏO/Á›œ/?80<Ë<§8 can anyone explain what is happening here? are the characters some form translation of pixel data by the text editor? maybe it is completely meaningless / an error? if not, is there a name for this type of data conversion or process?

  • rapid application developement tools for very basic GUI apps

    - by Jurij
    I know there are many RAD platforms out there. Infact there are so many that I'm having a hard time finding out which one fits me best. What I want is a RAD tool that would allow me to define a database data model (make DB tables) and then create (view and edit) forms for the various tables. Data input, updating and various queries should be easy and GUI should generate automatically. I'd like to add some additional functionality by coding (such as various complex calculations on the data). I'm a programmer so I'm willing to learn to use a more complete, full-blown RAD solution if you can point me to it (NetBeans and RubyOnRails being the two such frameworks that I'd would probably be high on the list). I'm currently doing Windows Forms logistics apps in .NET. I've actually developed a very crude and basic version of what I need, but I just know that there are solutions out there that are much better and I'd benefit by knowing how to use them. So in short, the basic requirements: * database based data storage (SQLite if possible) * very automated GUI creation * desktop based (as in: not a web app) * extendable by coding * used for creating simple data entry, view & query apps. So basically something like Oracle Forms or DotNetMushroom Rapid Application Developer. But for .NET and SQLite if possible.

  • Date formats in ActiveRecord / Rails 3

    - by cbmeeks
    In my model, I have a departure_date and a return_date. I am using a text_field instead of the date_select so that I can use the JQuery datepicker. My app is based in the US for now but I do hope to get international members. So basically this is what is happening. The user (US) types in a date such as 04/01/2010 (April 1st). Of course, MySQL stores it as a datetime such as 2010-04-01... Anyway, when the user goes to edit the date later on, it shows "01/04/2010" because I am using a strftime("%m/%d/%Y) which doesn't make sense....so it thinks it is January 4th instead of the original April 1st. It's like the only way to accurately store the data is for the user to type in: 2010-04-01 I hope all of this makes sense. What I am really after is a way for the user to type in (or use the datepicker) a date in their native format. So someone in Europe could type in 01/04/2010 for April 1st but someone in the US would type in 04/01/2010. Is there an easy, elegant solution to this? Thanks for any suggestions.

  • Tool for braceless, whitespace sensitive C syntax

    - by Ollie Saunders
    I'm writing some C at the moment and because I like whitespace sensitive syntax, I'd like to write it like this: #include <stdio.h> int main(void) printf("Hello, world!") return 0 Instead of this: #include <stdio.h> int main(void) { printf("Hello, world!"); return 0; } Does anybody know of a tool that will convert the former into the latter? Edit: I've really no interest in arguing with those that think this is a bad idea. By all means continue to think that, you have your reasons. But at least know this: I'm aware Python is a whitespace sensitive language but I have not used it. Why would I? I know Ruby already. Also know: I am not just learning C for the first time and I have used PHP and JavaScript for more than four years, so I am not requesting this out of some personal difficulty, lack of familiarity with block syntax, or dogmatic affiliation. I am also aware of what would be involved in writing one of these and that's not beyond my ability but I don't want this enough to justify spending the time writing one.

  • Javascript: prototypal inheritance and the prototype property

    - by JanD
    Hi, I have a simple code fragment in JS working with prototype inheritance. function object(o) { function F() {} F.prototype = o; return new F(); } //the following code block has a alternate version var mammal = { color: "brown", getColor: function() { return this.color; } } var myCat = object(mammal); myCat.meow = function(){return "meow";} that worked fine but adding this: mammal.prototype.kindOf = "predator"; does not. ("mammal.prototype is undefined") Since I guessed that object maybe have no prototype I rewrote it, replacing the var mammal={... block with: function mammal() { this.color = "brown"; this.getColor = function() { return this.color; } } which gave me a bunch of other errors: "Function.prototype.toString called on incompatible object" and if I try to call _myCat.getColor() "myCat.getColor is not a function" Now I am totally confused. After reading Crockford, and Flanagan I did not get the solution for the errors. So it would be great if somebody knows... - why is the prototype undefined in the first example (which is foremost concern; I thought the prototype of explicitly set in the object() function) - why get I these strange errors trying to use the mammal function as prototype object in the object() function? Edit by the Creator of the Question: These two links helped a lot too: Prototypes_in_JavaScript on the spheredev wiki explains the way the prototype property works relativily simple. What it lacks is some try-out code examples. Some good examples are provided by Morris John's Article. I personally find the explanations are not that easy as in the first link, but still very good. The most difficult part even after I actually got it is really not to confuse the .prototype propery with the internal [[Prototype]] of an object.

  • Tricky file parsing. Inconsistent Delimeters

    - by Ben Truby
    I need to parse a file with the following format. 0000000 ...ISBN.. ..Author.. ..Title.. ..Edit.. ..Year.. ..Pub.. ..Comments.. NrtlExt Nrtl Next Navg NQoH UrtlExt Urtl Uext Uavg UQoH ABS NEB MBS FOL ABE0001 0-679-73378-7 ABE WOMAN IN THE DUNES (INT'L ED) 1st 64 RANDOM 0.00 13.90 0.00 10.43 0 21.00 10.50 6.44 3.22 2 2.00 0.50 2.00 2.00 ABS The ID and ISBN are not a problem, the title is. There is no set length for these fields, and there are no solid delimiters- the space can be used for most of the file. Another issue is that there is not always an entry in the comments field. When there is, there are spaced within the content. So I can get the first two, and the last fourteen. I need some help figuring out how to parse the middle six fields. This file was generated by an older program that I cannot change. I am using php to parse this file.

  • Internal bug tracking tickets - Redmine, Trac, or JIRA

    - by Tai Squared
    I've been looking at setting up Redmine, Trac, or JIRA to track issues. I want to be able to have my development team create internal tickets that are never seen by clients, while clients can create/edit tickets that are seen by the internal team. From the Trac documentation, you can set permissions to create or view tickets, but it doesn't seem to allow for viewing only certain tickets. It may be possible with Trac Fine Grained Permissions, but doesn't appear so. The Redmine documentation mentions: Define your own roles and set their permissions in a click but doesn't appear to have the level of granularity. From the JIRA documentation: At the moment JIRA is only able to support security at a project level or issue level. Currently there is no field level security available. According to this question, Redmine doesn't support internal tickets, so you would have to use multiple projects. I don't want a situation where I would have to create multiple projects - one internal, one external and have the external tickets brought into the internal repository. It seems as this would lead to unnecessary overhead and inevitably, the projects wouldn't be in sync. Is there any way with any of these products (possibly through a plug-in if not in the core product itself) to specify these permissions, or simplify having two projects with different users and permissions that must still share information?

  • C# naming convention for enum and matching property

    - by Serge - appTranslator
    Hi All, I often find myself implementing a class maintaining some kind of own status property as an enum: I have a Status enum and ONE Status property of Status type. How should I solve this name conflict? public class Car { public enum Status { Off, Starting, Moving }; Status status = Status.Off; public Status Status // <===== Won't compile ===== { get { return status; } set { status = value; DoSomething(); } } } If the Status enum were common to different types, I'd put it outside the class and the problem would be solved. But Status applies to Car only hence it doesn't make sense to declare the enum outside the class. What naming convention do you use in this case? NB: This question was partially debated in comments of an answer of this question. Since it wasn't the main question, it didn't get much visibility. EDIT: Filip Ekberg suggests an IMO excellent workaround for the specific case of 'Status'. Yet I'd be interesting to read about solutions where the name of the enum/property is different, as in Michael Prewecki's answer. EDIT2 (May 2010): My favorite solution is to pluralize the enum type name, as suggested by Chris S. According to MS guidelines, this should be used for flag enums only. But I've come to like it more and more. I now use it for regular enums as well.

  • eventmachine and external scripts via backticks

    - by Maciek
    I have a small HTTP server script I've written using eventmachine which needs to call external scripts/commands and does so via backticks (``). When serving up requests which don't run backticked code, everything is fine, however, as soon as my EM code executes any backticked external script, it stops serving requests and stops executing in general. I noticed eventmachine seems to be sensitive to sub-processes and/or threads, and appears to have the popen method for this purpose, but EM's source warns that this method doesn't work under Windows. Many of the machines running this script are running Windows, so I can't use popen. Am I out of luck here? Is there a safe way to run an external command from an eventmachine script under Windows? Is there any way I could fire off some commands to be run externally without blocking EM's execution? edit: the culprit that seems to be screwing up EM the most is my usage of the Windows start command, as in: start java myclass. The reason I'm using start is because I want those external scripts to start running and keep running after the EM request is served

  • Hibernate triggering constraint violations using orphanRemoval

    - by ptomli
    I'm having trouble with a JPA/Hibernate (3.5.3) setup, where I have an entity, an "Account" class, which has a list of child entities, "Contact" instances. I'm trying to be able to add/remove instances of Contact into a List<Contact> property of Account. Adding a new instance into the set and calling saveOrUpdate(account) persists everything lovely. If I then choose to remove the contact from the list and again call saveOrUpdate, the SQL Hibernate seems to produce involves setting the account_id column to null, which violates a database constraint. What am I doing wrong? The code below is clearly a simplified abstract but I think it covers the problem as I'm seeing the same results in different code, which really is about this simple. SQL: CREATE TABLE account ( INT account_id ); CREATE TABLE contact ( INT contact_id, INT account_id REFERENCES account (account_id) ); Java: @Entity class Account { @Id @Column public Long id; @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true) @JoinColumn(name = "account_id") public List<Contact> contacts; } @Entity class Contact { @Id @Column public Long id; @ManyToOne(optional = false) @JoinColumn(name = "account_id", nullable = false) public Account account; } Account account = new Account(); Contact contact = new Contact(); account.contacts.add(contact); saveOrUpdate(account); // some time later, like another servlet request.... account.contacts.remove(contact); saveOrUpdate(account); Result: UPDATE contact SET account_id = null WHERE contact_id = ? Edit #1: It might be that this is actually a bug http://opensource.atlassian.com/projects/hibernate/browse/HHH-5091

  • Validating a wrong date entry in rich faces

    - by Hiral Lakdavala
    Hi, (On behalf of a collegue) In one of our functionality we have some date fields for inline edit where we have enabled manual input. If in rich:calendar component, we manually enter improper date or junk data it will not even call the action method. As per our requirement we need to display an error message for date validation for these kind of fields. Is there any way to track that the date entered in the calendar field is improper with this component. Code for the reference: <rich:calendar id="actualOpeningDtCal" rendered="#{!empty storeProgram.id}" value="#{storeProgram.actualOpeningDate}" placeholder="dd-mmm-yyyy" inputSize="20" enableManualInput="true" datePattern="dd-MMM-yyyy" buttonIcon="../content/images/calendar.png" showWeeksBar="false" showFooter="false"> <a4j:support event="oninputblur" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> <a4j:support event="oncollapse" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> </rich:calendar> Regards, Hiral

  • How can I put double quotes inside a string within an ajax JSON response from php?

    - by karlthorwald
    I receive a JSON response in an Ajax request from the server. This way it works: { "a" = "1", "b" = "hello 'kitty'" } But I did not succeed in putting double quotes around kitty. When I convert " to \x22 in the Ajax response, it is still interpreted as " by JavaScript and I cannot parse the JSON. Should I also escape the \ and unescape later (which would be possible)? How to do this? Edit: I am not sure if i expressed it well: I want this string inside of "b" after the parse: hello "kitty" If necessary I could also add an additional step after the parse to convert "b", but I guess it is not necessary, there is a more elegant way so this happens automatically? Edit2: The ajax page is generated by php. I tried several things now to create the value of b, all result in JSON parse error on the page: $b = 'hello "kitty"'; // no 1: //$b = str_replace('"',"\x22",$b); // or no 2: // $b = addslashes($b); // or no 3: //$b = str_replace('"','\"',$b); // or no 4: $b = str_replace('"','\\"',$b); echo '"b" : "' . $b . '"';

  • Magento - Show Custom Attributes in Grouped Product table.

    - by greencoconut
    I need to find a way to show the value of a custom attribute in place of the "Product Name" shown in the image below. I'm working with /app/design/frontend/default/defaultx/template/catalog/product/view/type/grouped.php The code below doesn't work(the custom attribute is yearmade): <?php if (count($_associatedProducts)): ?> <?php foreach ($_associatedProducts as $_item): ?> <tr> <td><?php echo $this->htmlEscape($_item->getYearmade()) ?></td> Any help would be appreciated. EDIT: So the answer turned out to be quite simple. You see what I failed to mention above was that there was indeed output... but that it was just a number (eg: 52). Turns out this was the ID for that custom attribute value (It was a Dropdown type of custom attribute). So in summary This works for custom attributes of type text: echo $this->htmlEscape($_item->getYearmade()) But for all other types of custom attribute (I think), the following should be used: echo $this->htmlEscape($_item->getAttributeText('yearmade')) I would not have discovered this without the most excellent answer provided by Alan Storm, below. Thank you sir.

  • Performance of java on different hardware?

    - by tangens
    In another SO question I asked why my java programs run faster on AMD than on Intel machines. But it seems that I'm the only one who has observed this. Now I would like to invite you to share the numbers of your local java performance with the SO community. I observed a big performance difference when watching the startup of JBoss on different hardware, so I set this program as the base for this comparison. For participation please download JBoss 5.1.0.GA and run: jboss-5.1.0.GA/bin/run.sh (or run.bat) This starts a standard configuration of JBoss without any extra applications. Then look for the last line of the start procedure which looks like this: [ServerImpl] JBoss (Microcontainer) [5.1.0.GA (build: SVNTag=JBoss_5_1_0_GA date=200905221634)] Started in 25s:264ms Please repeat this procedure until the printed time is somewhat stable and post this line together with some comments on your hardware (I used cpu-z to get the infos) and operating system like this: java version: 1.6.0_13 OS: Windows XP Board: ASUS M4A78T-E Processor: AMD Phenom II X3 720, 2.8 GHz RAM: 2*2 GB DDR3 (labeled 1333 MHz) GPU: NVIDIA GeForce 9400 GT disc: Seagate 1.5 TB (ST31500341AS) Use your votes to bring the fastest configuration to the top. I'm very curious about the results. EDIT: Up to now only a few members have shared their results. I'd really be interested in the results obtained with some other architectures. If someone works with a MAC (desktop) or runs an Intel i7 with less than 3 GHz, please once start JBoss and share your results. It will only take a few minutes.

  • C# StripStatusText Update Issue

    - by ikurtz
    I am here due to a strange behaviour in Button_Click event. The code is attached. The issue is the first StripStatus message is never displayed. any ideas as to why? private void FireBtn_Click(object sender, EventArgs e) { // Control local controls for launching attack AwayTableLayoutPanel.Enabled = false; AwayCancelBtn.Enabled = false; FireBtn.Enabled = false; ////////////// Below statusBar message is never displayed but the folowing sound clip is. GameToolStripStatusLabel.Text = "(Home vs. Away)(Attack Coordinate: (" + GameModel.alphaCoords(GridLock.Column) + "," + GridLock.Row + "))(Action: Fire)"; //////////////////////////////////////////// if (audio) { SoundPlayer fire = new SoundPlayer(Properties.Resources.fire); fire.PlaySync(); fire.Dispose(); } // compile attack message XmlSerializer s; StringWriter w; FireGridUnit fireGridUnit = new FireGridUnit(); fireGridUnit.FireGridLocation = GridLock; s = new XmlSerializer(typeof(FireGridUnit)); w = new StringWriter(); s.Serialize(w, fireGridUnit); ////////////////////////////////////////////////////////// // send attack message GameMessage GameMessageAction = new GameMessage(); GameMessageAction.gameAction = GameMessage.GameAction.FireAttack; GameMessageAction.statusMessage = w.ToString(); s = new XmlSerializer(typeof(GameMessage)); w = new StringWriter(); s.Serialize(w, GameMessageAction); SendGameMsg(w.ToString()); GameToolStripStatusLabel.Text = "(Home vs. Away)(Attack Coordinate: (" + GameModel.alphaCoords(GridLock.Column) + "," + GridLock.Row + "))(Action: Awaiting Fire Result)"; } EDIT: if I put in a messageBox after the StripStatus message the status is updated.

  • [SOLVED]: Delegate OpenID to Google (NOT Google Apps)

    - by Rio
    OK, I searched this question on SO but no good answer. After spent some time I figured out how to do it. I'm going to answer this myself as a way to share it. Not sure if this is the correct way to use SO, but here it goes: Now it is possible delegate OpenID to your Google account (not Google Apps). No, this is not using the demo OpenID provider using App Engine. This is your REAL Google account! First you need to enable your Google Profiles. Try to view your profile and edit it, there should be an option to set your Profile URL. You have two choices there: either use your Gmail account name (without the @gmail.com part) as your profile id, or a random number assigned to you. It's up to you to decide which one to use. Either way, that id is your profile id below. Now add the following HTML code to your delegating page: <link rel="openid2.provider" href="https://www.google.com/accounts/o8/ud?source=profiles" > <link rel="openid2.local_id" href="http://www.google.com/profiles/[YOUR PROFILE ID]" > And it's done. Now try login SO with your custom url!

  • how can I convert String to SecretKey

    - by Alaa
    I want to convert String to secretKey public void generateCode(String keyStr){ KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(128); // 192 and 256 bits may not be available // Generate the secret key specs. secretKey skey=keyStr; //How can I make the casting here //SecretKey skey = kgen.generateKey(); byte[] raw = skey.getEncoded(); } I try to use BASE64Decoder instead of secretKey, but I face a porblem which is I cannot specify key length. EDIT: I want to call this function from another place static public String encrypt(String message , String key , int keyLength) throws Exception { // Get the KeyGenerator KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(keyLength); // 192 and 256 bits may not be available // Generate the secret key specs. //decode the BASE64 coded message SecretKey skey = key; //here is the error raw = skey.getEncoded(); SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); // Instantiate the cipher Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, skeySpec); System.out.println("msg is" + message + "\n raw is" + raw); byte[] encrypted = cipher.doFinal(message.getBytes()); String cryptedValue = new String(encrypted); System.out.println("encrypted string: " + cryptedValue); return cryptedValue; } Any one can help, i'll be very thankful.

  • C sharp code cleanup : resharper

    - by Ankit Rathod
    Hello, I just used Resharper in one application and it made me feel as if i don't know how to code at all in C# :(. On every line it gave me it's suggestions :- Few of Resharper's favorite suggestions are :- 1) SomObject o = new SomeObject(); Resharper will convert to : var o = new SomeObject() 2) this.Loaded += new RoutedEventHandler(MainPage_Loaded); to this.Loaded += MainPage_Loaded; 3) convert my variables and putting _ in front of all instance variables. 4) Removing class parent's name. I tested this on Silverlight. public partial class MainPage : UserControl to public partial class MainPage EDIT :- 5) replace instance variable this.variable = somevalue to variable = somevalue Are all of these really necessary? Is it really going to affect the efficiency of my program? I mean what good is it going to do by replacing my class names with var keyword. After all var is also replaced with class name at compile time. Is it doing because it has been programmed to do or do these things really affect in some or another way? Thanks in advance :)
