• How to check if a variable is defined in a Master file in ASP.NET MVC

  - by Mortanis

  I've got a Site.Master file I've created to be my template for the majority of the site, with a navigation. This navigation is dynamically created, based on a recursive Entity (called Page) - Pages with a parentID of 0 are top level, and naturally each child carries it's parent's Id in that field. I've created a quick little HTML Helper that accepts the ID of an Page and generates the nav by doing a foreach on the children that have a parentId matching the passed Id. On the majority of the site, I want the Site.Master to use a parentId of 0, but if I'm on a strongly typed View displaying a Page, I naturally want to use the Id of the page. Is there a way to do such conditional logic in a Site.Master (and, does that violate MVC rules)? "If I'm on a strongly typed Page of /Page/{Id}, use the Id render nav, else use 0"

• How do you handle files that can't support concurrent edits in Mercurial?

  - by Scott Whitlock

  I'm using Mercurial with TortoiseHg. Each developer has their own repositories, and there's one central repository on the server for synchronizing our changes. (This will sound lame, but we're using it to manage the source for a legacy VB6 project. Nothing we can do about that...) As has been pointed out elsewhere, there is a big problem in VB6 with merging the .frx (form resources) files. So code changes seem to merge fine, but if two developers both make changes at the same time in the form design view, we can't merge. I'm ok with disallowing concurrent edits, but of course the whole point of Mercurial is that it's distributed so there is no option to force a file to be locked before editing. I don't believe there's a Mercurial solution for this, so I'm wondering: other developers who are using Mercurial for version control, do you have some 3rd party tool that assists with locking files for editing in the cases where it's necessary? Did we make a mistake using Mercurial instead of something like SVN?

• How to implement Android Pull-to-Refresh

  - by yuku

  In Android applications such as Twitter (official app), when you encounter a ListView, you can pull it down (and it will bounce back when released) to refresh the content. I wonder what is the best way, in your opinion, to implement that? Some possibilities I could think of: An item on top of the ListView - however I don't think scrolling back to item position 1 (0-based) with animation on the ListView is an easy task. Another view outside the ListView - but I need to take care of moving the ListView position down when it is pulled, and I'm not sure if we can detect if the drag-touches to the ListView still really scroll the items on the ListView. Any recommendations?

• How do I make a universal iPhone / iPad application that programmatically uses UISplitViewController

  - by arash13

  I couldn't find a good answer anywhere to this. I am using a UINavigationController for my iPhone app, with everything is generated programmatically, nothing in Interface Builder. I am trying to port my app to iPad, using a UISplitViewController and my existing UINavigationController, but I am not sure where I should have the logic of my program separating the view controllers for iPhone or iPad. Do I set up my main file to use a different app delegate or do I use the same app delegate and have the user interface conditionally set up within it? Besides this, whenever I try to compile my app on the simulator it does not recognize the UISplitViewController or even the condition in which I check if the class exists. Can please someone put me in the right direction, remembering that I am not using any xibs?

• UITextView on iPad INCREDIBLY Slow

  - by Sj

  I have an NSMutableArray of custom views (that are pretty much 1 UITextView and 1 UILabel with a custom back ground image), these are created as they are need (I start with 2 (though the first one is only 2 UITextFields and the other is normal) of these). Now my issue here seems to be this: as soon as I try to edit any UITextView past the one in the 2nd view, it starts to run incredibly slow, not the app, just the textview. For example, as I type, the little blinky guy lags behind the text and when I click to copy/paste/cut/etc you can see the little balloon fly in from the upper left corner every time. I have run the static analyzer for leaks and come up with nothing and run it alongside some other the testing software in XCode and it does not appear to have any reason for this. Any help would be greatly appreciated.

• MOSS Faceted Search 3.0

  - by nav

  Hi, Has anyone installed Faceted Search v3.0 for MOSS working with date columns? When I map a column of DateTime type and click the Search BreadCrumb webpart "remove filter" link (next to the edit filter link) an exception is thrown. The search Breadcrumb webpart throws an error when I click the "Remove filter" link (this is the one represented by the broken link icon - next to the "Edit facet" icon). This seems to only occur after clicking the "Remove filter" link for Facets of DateTime type after which it occurs on every instance for all Facets. The error thrown is posted here: http://facetedsearch.codeplex.com/Thread/View.aspx?ThreadId=213398 Many Thanks, Nav

• Packaging one or two plugins as a standalone RCP application?

  - by Martin Cowie

  I have a handful of Eclipse plugins that I maintain. They are proving useful enough that non Eclipse users have asked for them without the overhead of a full eclipse install. I am certain this is possible, but uncertain how to make this possible. My attempts at creating a standalone RCP app and then including my plugins as dependencies have given me mixed results. More specifically, my perspective tries to instantiate a view from a plugin and fails (silently)... public void createInitialLayout(IPageLayout layout) { layout.addStandaloneView( "myPlugin.ID", false, IPageLayout.LEFT, 0.25f, editorArea); } ... but as the same plugin implements a search extension, it does show up in the standard Eclipse search dialog. Are there any resources that hardened Eclipse tars can point me to, that will help overcome this hurdle? M.

  Hi, I have apache and mysql set up on my local machine (Mac). Whenever I go to any of my local sites I get the "Error establishing a database connection" whenever anything mySql related happens.

• Jquery Text Variable

  - by Batfan

  I am trying to get jquery to pick up variable that I am defining and I'm having issues doing it. $.ajax({ url: "sitemap.php", cache: false, success: function(html){ $("#results").append(html); var $seriestitle = $("#define-title").text(); $('#results a:contains("$seriestitle")').addClass('current-series'); $('a:not(".current-series")').hide(); } }); This is the code I am using.

• Model Binding an IList of selected items only

  - by jeef3

  I have an action method setup: public ActionResult Delete(IList<Product> products) And a table of products in my view. I have got Model Binding working so that on submit I can populate the products list. But I would like to populate it with only the products that are selected via a checkbox. I think I could do it by changing the action method to this: public ActionResult Delete(IList<Product> products, IList<int> toDelete) And passing the list of check boxes to the toDelete but I would really like to avoid changing the method signature if possible. Is there a way to pass only the selected items? Or am I going to have to write a custom ModelBinder?

• GWT Date Picker Format problem when saving a java date through hibernate in postgresql

  - by Noor

  Hi, I am using Java Date and Hibernate which is then being saved in the database (Postgresql). I am not that good in hibernate Part of the Mapping File <property name="DateOfBirth" type="java.util.Date"> <column name="DATEOFBIRTH" /> </property> I am using GWT Date picker Short date format i.e. yyyy-MM-dd. I am getting the value from the date picker using View.getUserDateOfBirth().getValue() But when I am saving the date 2010-11-30 into the datebase it is saving it as 2010-11-30 00:00:00 instead of 2010-11-30 So, I want it to be saved in the database as in this format 2010-11-30??

• Simple github fetch/merge not pulling in remote branch?

  - by chum of chance

  I have a project I forked on github to my repository. I made changes on the "experiment" branch of the project the committed the project to my fork. If you go to my branch on Github you can see the that the experiment branch was correctly committed. I would like to merge the experiment branch with the original repo (which I have rights to). I issued the following commands: git clone [email protected]:originalrepo/theproject.git git checkout -b experiment origin/experiment cd theproject git remote add experiment [email protected]:chumofchance/theproject.git git fetch experiment git merge experiment "Already up to date" However, when I view the project in explorer, it appears that nothing has changed. Am I screwing something up in regards to fetching the experiment branch (vs the master branch)?

• PHP/Javascript - get php variable within javascript

  - by McNabbToSkins

  I have run into an interesting problem. I am currently developing php page and need to access a php variable within the javascript onload. $(document).ready(function() { var temp = <?php $page_id ?> } is this valid? I know that this might seem weird and not be allowed but I am developing a page that has two popup windows. The windows are created using the same view template and there is no way to distinguish between each other. If I stored a hidden value on the page with information unique to the page like so <input type="hidden" value="<?php $page_id ?> id="page_id" /> if there are two views open at the same time there is no way for me to get a unique page id like so var temp = $("#page_id").val(); Because there are two views witht he same input id that is not unique. Long story short is it valid to reference a php variable in the javascript.

• Asp.Net MVC2 TekPub Starter Site methodology question

  - by Pino

  Ok I've just ran into this and I was only supposed to be checking my emails however I've ended up watching this (and not far off subscribing to TekPub). http://tekpub.com/production/starter Now these app is a great starting point, but it raises one issue for me and the development process I've been shown to follow (rightly or wrongly). There is no conversion from the LinqToSql object when passing data to the view. Are there any negitives to this? The main one I can see is with validation, does this cause issues when using MVC's built in validation as this is somthing we use extensivly. Because we are using the built in objects generated by LinqToSql how would one go about adding validation, like [Required(ErrorMessage="Name is Required")] public string Name {get;set;} Interested to understand the benifits of this methodology and any negitives that, should we take it on, experiance through the development process.

• Best calculator software to help programmers

  - by RHaguiuda

  As a embedded systems programmer I always need to make lots of base conversions (dec to hex, hex to bin and so on...), and I must admit: Windows 7 calculator is a good calc, but too limited in my point of view. I work a lot with communications protocols and it`s common to need some base conversion in this field of knowledge. I`m looking for a calculator software (not a hardware one), to help with base conversions, but it must also support scientific calc. Can anyone help on this? Since this subject is intended to help programmers, I did not ask this in SuperUser.com. Thanks.

• XDocument holding onto Memory?

  - by Jon

  I have an appplication that does a XDocument.Load from a 20mb file and then gets passed to a form to view its contents: openFileDialog1.FileName = ""; if (openFileDialog1.ShowDialog() == DialogResult.OK) { AuditFile = XDocument.Load(openFileDialog1.FileName); fmAuditLogViewer AuditViewer = new fmAuditLogViewer(); AuditViewer.ReportDocument = AuditFile; AuditViewer.Init(); AuditViewer.ShowDialog(); AuditViewer.Dispose(); AuditFile.RemoveNodes(); AuditFile = null; } In Task Manager I can see the memory being used by my application shoot up when I open this file. When I have finished viewing this file in my application I call : myXDocument.RemoveNodes(); myXDocument = null; However the memory use in Task Manager is still pretty high against my app. Is the XDocument still being held in memory and can I decrease the memory usage by my app?

I want to select two photos of size 1600x1200 from photo library and then merge both into a single image and save that new image back to the photo library. However, I can't get the right size for the merged image. I take two image views of frame 320x480 and set the view's image to my imported images. After manipulating the images (zooming, cropping, rotating), I then save the image to album. When I check the image size it shows 600x800. How do I get the original size of 1600*1200? I've been stuck on this problem from two weeks! Thanks in advance.

• h:commandButton not working within PrimeFaces p:dataTable

  - by JamesB

  I have a PrimeFaces datatable. For each row in this table, I want to allow the user to update/delete the row entry (a user). <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:p="http://primefaces.prime.com.tr/ui"> <h:head> <link type="text/css" rel="stylesheet" href="themes/bluesky/skin.css" /> </h:head> <h:body> <center> <h:form> <p:panel id="viewUsersPanel" header="View Users"> <p:dataTable var="user" value="#{uController.users}" emptyMessage="No Users Found."> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="Name" /> </f:facet> <h:outputText value="#{user.name}" /> </p:column> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="Postal Address" /> </f:facet> <h:outputText value="#{user.address}" /> </p:column> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="Phone Number" /> </f:facet> <h:outputText value="#{user.phone}" /> </p:column> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="Email Address" /> </f:facet> <h:outputText value="#{user.email}" /> </p:column> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="DOB" /> </f:facet> <h:outputText value="#{user.dob}"> <f:convertDateTime pattern="dd-MMM-yyyy" /> </h:outputText> </p:column> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="No. Memberships" /> </f:facet> <h:outputText value="#{user.numberOfMemberships}" /> </p:column> <p:column style="text-align: center;"> <f:facet name="header"> <h:outputText value="Actions" /> </f:facet> <h:commandButton value="Update" action="#{uController.update}" /> <h:commandButton value="Delete" action="#{uController.delete}" /> </p:column> </p:dataTable> <h:panelGrid columns="2" cellpadding="2" id="footerPanelGrid" border="0"> <h:commandButton action="#{uController.home}" value="Home Page" /> </h:panelGrid> </p:panel> </h:form> </center> </h:body> </html> However, neither of the buttons work. Instead they appear to simply refresh the view page. I have ran the app in debug and neither update or delete method is hit. I suspect this may be due to using h:commandButton within a p:dataTable. However, I have also tried p:commandButton but to no avail. For reference, here is a snippet of the UserController class: @ManagedBean(name="uController") public class UserController extends AbstractController { private Collection<User> users; ... public String update() { System.out.println("Ready for update"); return "update-user"; } public String delete() { System.out.println("Ready for delete"); return "delete-user"; } ... }

• Best way to create preview functionality in Rails

  - by slythic

  Hi all, I'm looking to implement preview functionality in my posts scaffold. All I need to do is allow a user to enter information in the new view (/posts/new) and then replace the submit button with a preview button. Once the preview button is clicked, the user is routed to the preview page (probably /posts/new/preview). If the user wants to make a change they would click 'go back' or if they are happy with the post they can then submit the post. I found this article (http://eyedeal.team88.org/node/105) but it seems dated. Any ideas on what the best approach for this would be? Many thanks, Tony
