• Good resources for Wordpress?

  - by Smickie

  Hi, I'm building quite a large site, no e-commerce, but a a lot of specific content to be managed. For some reason, the client wants Wordpress. There is no way of getting around this... I've used Wordpress before to rapidly develop blogs, but that's about it. If anything goes beyond the scope of Wordpress I'll use a framework in something (Rails/Cake). This build is going to require custom plug-ins and widgets, so what I'm asking is how is the best way to go about learning how Wordpress and best practices for plug-ins and widgets?

• Obj-c Turning long string into multidimensional array

  - by Phil

  I have a long NSString, something like "t00010000t00020000t00030000" and so on. I need to split that up into each "t0001000". I'm using... NSArray *tileData = [[GameP objectForKey:@"map"] componentsSeparatedByString:@"t"]; And it splits it up, but the "t" is missing, which I need (although I think I could append it back on). The other way I guess would be to split it up by counting 8 char's, although not sure how to do that. But ideally I need it split into a [][] type array so I can get to each bit with something like... NSString tile = [[tileData objectAtIndex:i] objectAtIndex:j]]; I'm new to obj-c so thanks for any help.

• Secure password transmission over unencrypted tcp/ip

  - by academicRobot

  I'm in the designing stages of a custom tcp/ip protocol for mobile client-server communication. When not required (data is not sensitive), I'd like to avoid using SSL for overhead reasons (both in handshake latency and conserving cycles). My question is, what is the best practices way of transmitting authentication information over an unencrypted connection? Currently, I'm liking SRP or J-PAKE (they generate secure session tokens, are hash/salt friendly, and allow kicking into TLS when necessary), which I believe are both implemented in OpenSSL. However, I am a bit wary since I don't see many people using these algorithms for this purpose. Would also appreciate pointers to any materials discussing this topic in general, since I had trouble finding any.

• ClickOnce deployment with VS2008 - prerequisites not installing on Windows 7 (only)

  - by dataft

  I have a VS2008 clickonce application with a custom prerequiste, which I install with the bootstrapper. When deployed online, the prerequisite is downloaded and installed fine. No problems. When deployed via CD to a Windows XP machine, also fine as above. No problems. However, when deployed via CD to a Windows 7 machine: the prerequisite is downloaded - good then the user is asked for permission to the run the file - good then the installation of the prerequiste is just SKIPPED - bad and the ClickOnce application installation begins without the prerequisite - bad Has anyone encountered this weird behaviour? I cannot find a solution anywhere.

• Confusion over manual/automatic sizing of Flash Sprite Objects

  - by John

  If I have a custom class subclassing Sprite and it draws some simple objects, how does this work with respect to the Sprite.width & Sprite.height properties? It seems I can draw (for example) a rectangle of any size, bigger than the Sprite size. Similarly if I set the width/height properties, what happens to the content already drawn? As a use-case, I might have a stick-man which is drawn as a set of lines, I want to set the man's height and the rendering is scaled to this. Are there any issues with width/height being auto-calculated or am I misunderstanding what these properties actually mean?

• Performing time consuming operation on STL container within a lock

  - by Ashley

  I have an unordered_map of an unordered_map which stores a pointer of objects. The unordered map is being shared by multiple threads. I need to iterate through each object and perform some time consuming operation (like sending it through network etc) . How could I lock the multiple unordered_map so that it won't blocked for too long? typedef std::unordered_map<string, classA*>MAP1; typedef std::unordered_map<int, MAP1*>MAP2; MAP2 map2; pthread_mutex_lock(&mutexA) //how could I lock the maps? Could I reduce the lock granularity? for(MAP2::iterator it2 = map2.begin; it2 != map2.end; it2++) { for(MAP1::iterator it1 = *(it2->second).begin(); it1 != *(it2->second).end(); it1++) { //perform some time consuming operation on it1->second eg sendToNetwork(*(it1->second)); } } pthread_mutex_unlock(&mutexA)

• What is the best practice for accessing Model using MVVM pattern

  - by Dzenand

  I have a database that communicates with webservices with my Model (own thread) and exposes Data Objects. My UI application consists of different Views and ViewModels and Custom Controls. I'm using ServiceProvider (IServiceProvider) to access the Model and route the events to the UI thread. Communication between the ViewModels is handeled by a Messenger. Is this way to go? I was also wondering what is the best way to strucutre the DataObjects At the moment i have the DataObjects that have a hierarchy structure but does not support INotifyProperty though the children list are of type of ObservableCollection. I have no possiblity to implement notifypropertychange on the properties. I was wondering the best way of making them MVVM friendly. Implementing a partial class and adding all the properties or commands that are necessary or wrapping all the DataObjects and keep the Model list and MVVM list in sync. All thoughts and ideas are appreciated.

• LinqToSql: How can I create a projection to adhere to DRY?

  - by mhutter

  Just wondering if there is a way to take some of the repitition out of a LINQ to SQL projected type. Example: Table: Address Fields: AddressID, HouseNumber, Street, City, State, Zip, +20 more Class MyAddress: AddressID, HouseNumber, Street (Only 3 fields) LINQ: from a in db.Addresses select new MyAddress { AddressID = a.AddressID, HouseNumber = a.HouseNumber, Street = a.Street } The above query works perfectly, and I understand why something like this will return all 20+ fields in each row: from a in db.Addresses select new MyAddress(a); class MyAddress { public MyAddress(Address a) { this.AddressID = a.AddressID, this.HouseNumber = a.HouseNumber, this.Street = a.Street } } Which leads me to my Question: Is it possible to implement some kind of helper function or extension method to "map" from the LINQ model to MyAddress yet only return the necessary fields in the query result rather than all of the fields?

• Add Attribute (System.Attribute variety) to .aspx page - not the code-behind

  - by Macho Matt

  I am creating a custom Attribute (extending System.Attribute). I know I can put it on another class easily enough by doing the following. [MattsAttribute] public class SomeClassWhichIsACodeBehind { However, I need to be able to test this attribute easily, and putting it in the code-behind would cause a lot of extra effort to get it deployed to an environment which would respond to the behavior of attribute. What I would like to do: declaratively apply this attribute to the .aspx page itself (which is really just another class that inherits from the code-behind). Is this possible? If so, what is the proper syntax for doing this?

• iPhone switching views without first view being reset

  - by user298261

  Heya! I'm making a role-playing game, and I want to have a Map View and a Battle Screen. With the possibility of other screens as well. I thought the best way to achieve this was to use multiple NIB files. When I prototyped this by have one view that creates content, switches to the next view, and then back, the content on the original view was reset. How do I make it so that the first view doesn't reset the data each time it's loaded? Thanks!

• Rails routing issue

  - by Brob

  Hi I've just started learning rails and been going through some tutorials from learning rails (http://www.buildingwebapps.com/podcasts/79335-putting-the-page-contents-into-the) The tutorials appear to be Rails v2 and I'm on Rails v3 There is a line in the routes file which appears to be causing a problem map.view_page ':name', :controller => 'viewer', :action => 'show' The line works for the front end view i.e. my viewer controller but not for the back end I get the error NoMethodError in Viewer#show I think this has something to do with the view I am using and the line <%= @page.body %> I know it's difficult without the full code but if anyone can help that would be awesome

• how to prevent myControl.g.cs from overwriting with wrong base class

  - by Jonny Cundall

  I've got two custom cursors for my app, MyCursor and MyOtherCursor, both of which were designed in xaml, and I added some behaviour in the xaml.cs for each of them. This behaviour was the same for both so I had them inherit from a base class to reduce code duplication. public partial class myCursor: CursorBase { public InterchangeCursor() { InitializeComponent(); } } public class CursorBase : UserControl { public virtual void MoveTo(Point pt) { this.SetValue(Canvas.LeftProperty, pt.X); this.SetValue(Canvas.TopProperty, pt.Y); } } my problem is that if I change something in the xaml for MyCursor, the MyCursor.g.cs file is regenerated, and instead of inheriting from CursorBase, the partial class in the g.cs inherits from System.Windows.Controls.UserControl. Since the other side of the partial class in the xaml.cs file still inherits CursorBase, a build error occurs. I'm finding it annoying fixing the g.cs file each time. Does anyone know how to prevent this happening?

• What is the best way to set default values in ActiveRecord?

  - by ryw

  What is the best way to set default value in ActiveRecord? I see a post from Pratik that describes an ugly, complicated chunk of code: http://m.onkey.org/2007/7/24/how-to-set-default-values-in-your-model class Item < ActiveRecord::Base def initialize_with_defaults(attrs = nil, &block) initialize_without_defaults(attrs) do setter = lambda { |key, value| self.send("#{key.to_s}=", value) unless !attrs.nil? && attrs.keys.map(&:to_s).include?(key.to_s) } setter.call('scheduler_type', 'hotseat') yield self if block_given? end end alias_method_chain :initialize, :defaults end YUCK! I have seen the following examples googling around: def initialize super self.status = ACTIVE unless self.status end and def after_initialize return unless new_record? self.status = ACTIVE end I've also seen people put it in their migration, but I'd rather see it defined in the model code. What's the best way to set default value for fields in ActiveRecord model?

• JPA hibernate OneToOne mapping

  - by Stupidfrog

  enviroment: hibernate 4.1.6.final spring 3.1.2.release spring jpa 1.1.0.release postgresql 9.1-901-1.jdbc4 there is 2 table public A { private Long id; private Long name; } public B { private Long id; private Long table_a_id; } the A.id and B.id is sequential, unique , but no related.(means they are separately id for their own table). how to do mapping? i have tried some method, however the result is not i wanted, because it bind wrong. for example: public A { .... @OneToOne @JoinColumn(name = "id") private B table_b } public B { ... @JsonIgnore @OneToOne(mappedBy = "table_b") private A table_a; } when i query A the result is { "id":5, "table_b":{ "id":5, "table_a_id":4 } } obviously the data join by using their id but not joining using table_a_id. what i expect is { "id":4, "table_b":{ "id":5, "table_a_id":4 } } so can somebody teach me that, how to map this 2 table by using table b table_a_id(foregin key)

• What is the best way to store categorical references in SQL tables?

  - by jlafay

  I'm wanting to store a wide array of categorical data in MySQL database tables. Let's say that for instance I want to to information on "widgets" and want to categorize attributes in certain ways, i.e. shape category. For instance, the widgets could be classified as: round, square, triangular, spherical, etc. Should these categories be stored within a table to reference them best from an application? Another possibility, I would imagine, would be to add a column to widgets that contained a shape column that contained a tiny int. That way my application could search shapes by that and then use a coordinating enum type that would map the shape int meanings. Which would be best? Or is there another solution that I'm not thinking of yet?

• How do I use a UIView subclass as a container?

  - by dxq

  I'm trying to subclass UIView to create a custom view that is essentially a container. The subclass contains a UILabel and a UIImageView- I can't make either of them show up. Here's an example of what I've been trying: In my main view controller: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { ViewClass *myView = [[ViewClass alloc] initWithFrame:CGRectMake(100, 100, 150, 150)]; [view addSubview:myView]; } return self; } In my UIView subclass: - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { UILabel *word = [[[UILabel alloc] initWithFrame:[self bounds]] autorelease]; word.text = @"WHY ISN'T THIS SHOWING UP!?"; [self addSubview:word]; } return self; } Can anyone explain what I'm doing wrong? I'm way out of practice with UIKit and Obj-C, and I figure I'm probably missing something obvious.

• Is there any way to use GUIDs in django?

  - by Jason Baker

  I have a couple of tables that are joined by GUIDs in SQL Server. Now, I've found a few custom fields to add support for GUIDs in django, but I tend to shy away from using code in blog posts if at all possible. I'm not going to do anything with the GUID other than join on it and maybe assign a GUID on new entries (although this is optional). Is there any way to allow this using django's built-in types? Like can I use some kind of char field or binary field and "trick" django into joining using it? If it's any help, I'm using django-pyodbc.

• System.Data.DataException thrown when launching application after install

  - by jwarzech

  I currently have a (Visual Studio 2008) installer that has a 'Primary output...' custom action under 'Install' with 'InstallerClass' set to false. During the install I get a System.Data.DataException. When I run the debugger I am getting an exception being thrown from a bit of database access code that runs when the application starts. The database access is using Windows Authentication and works correctly when the application is started manually. Is this something to do with permission settings not allowing db access when launched from the installer? (I'm out of ideas)

• Change the contents of a UITableView via a swipe?

  - by Mark

  Im currently using a UITableView like any other, and I am researching into the ability to perform a swipe gesture on the screen, which will then shift the contents of the visible table over to display new content for example: swiping right-to-left on the screen would change (via animation) the contents within each of the cells on screen to show new data. What I can do is detect a swipe on the cells, or perhaps on the UITableViewController, but what I dont know how to do two fold: 1) Change data in all cells (could you have a set of hidden views within a custom table cell that animate in and out of each cell per swipe?) 2) How can you do this to all cells? Thanks a lot Mark

• Quick way to do data lookup in PHP

  - by Ghostrider

  I have a data table with 600,000 records that is around 25 megabytes large. It is indexed by a 4 byte key. Is there a way to find a row in such dataset quickly with PHP without resorting to MySQL? The website in question is mostly static with minor PHP code and no database dependencies and therefore fast. I would like to add this data without having to use MySQL if possible. In C++ I would memory map the file and do a binary search in it. Is there a way to do something similar in PHP?

• Is is possible to make a shaped, alpha-blended dialog?

  - by jgaa

  I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

• Serialising and Deserialising Requests and Responses exactly as WCF does

  - by PeteAC

  I need to deserialise SOAP request XML to .Net request object and to serialise .Net response object to SOAP response XML. I need this to work exactly as WCF does, using the same XML element local names and namespace URIs. The .Net request and response classes were generated from WSDL using SVCUTIL. I have looked at XmlSerializer class, which does most of it, but doesn't take notice of certain WCF-specific custom attributes, like MessageBodyMemberAttribute. I also looked at DataContractSerializer, but that had exceedingly strange ideas about what element names and namespaces to use. Finally, I tried XmlSerializer with an XmlTypeMapping generated by a SoapReflectionImporter; this didn't seem to use any namespaces at all. I rather suspect that I need to be using one of the above techniques, but with some additional subtlety, of which I am unaware. But perhaps there is an entirely different approach? All suggestions welcome.

• UIView added with incorrect orientation

  - by mx12

  So I have been working on a problem with UIView on the iPad. Essentially I have a splitview as the root view and I want to overlay my custom image view over top of the splitview (This is because the splitview must be the root view). The problem that I have, is when I call addSubview on my splitview the subview gets displayed in its default orientation, with no regard to the iPad's current orientation. Any suggestions on what I am doing wrong or flag I am not setting? Thanks! Code that I am using to add the view: [splitViewController.view addSubview: myImageController.view]; Example screenshots: http://www.engineering.uiowa.edu/~krtaylor/so/

• How do I get certain code to execute before every single controller action in ASP.NET MVC 2?

  - by Chris

  I want to check some things about the state of the session, the user agent, etc, and possibly take action and return a special view BEFORE a controller method gets a chance to execute. For example: Most common: User requests Home/Index System checks to make sure x != 0. x does not equal zero, so the Home/Index controller executes like normal. But, sometimes: User requests Home/Index System checks to make sure x != 0. x DOES equal zero. The user must be notified and the requested controller action cannot be allowed to execute. I think this involves the use of ActionFilters. But I have read about them and I don't understand if I can preempt the controller method and return a view before it executes. I am sure I could execute code before the controller method runs, but how do I keep it from running in some instances and return a custom view, or direct to a different controller method?
