• PayPal testing without using Sandbox

  - by Webbo

  I am developing a website in PHP that accepts PayPal payments. It uses the IPN from PayPal and has a custom payment template etc etc. It all works great through the Sandbox server but when it comes to showing my client, I don't want to have to tell them to login to/create a Sandbox account, create a buyer account and make a payment - he hasn't got time for that and probably won't be able to do it. Therefore, my question is - is there any simple way that I can show my client the PayPal integration in "test mode" without him using the sandbox? I realise that I can set the transaction value to 0.01 and just test on the live PayPal server but that isn't an ideal solution. Cheers! Edit: Just to better explain what I mean, this is what my client sees when he first goes to checkout; As you can see, he has to login to his Sandbox account before then purchasing the item using the buyer email that he sets up. It's just confusing and totally non user-friendly.

• crunching multiple js files during development

  - by Yaron Naveh

  I'm writing a backbone.js app. I have multiple js, css and html template files. I also have a script to crunch them into a single file so it is faster to download. How should I work during development: Add a listener to the file system and after every change compile the files so I can see it in a browser. This implies a 1-2 seconds overhead before I can see what I did, which is annoying for html fine-tuning. Somehow browse using the multiple files during development and only crunch before going to production. This means I need to have a separate index.html for dev and prod. What's your take?

• Python imports by folder module

  - by colinmarc

  I have a directory structure: example.py templates/ __init__.py a.py b.py a.py and b.py have only one class, named the same as the file (because they are cheetah templates). For purely style reasons, I want to be able to import and use these classes in example.py like so: import templates t = templates.a() Right now I do that by having this in the template folder's __init__.py: __all__ = ["a", "b"] from . import * However, this seems pretty poor (and maybe superfluous), and doesn't even do what I want, as I have to use the classes like this: t = templates.a.a() Thoughts?

• d13slideshow for WordPress and "URL file-access is disabled"

  - by windyjonas

  I'm taking my chances with WordPress 3.0 beta 1 (single user) Unfortunately, i ran into problems with d13slideshow. I configured the plugin to display 5 latest from a category, added <?php d13slideshow(); ?> to home.php, but it bombed: function.getimagesize: URL file-access is disabled in the server configuration in /<snip>/wp-content/plugins/d13slideshow/d13slideshow.php on line 538 Warning: getimagesize(http://<snip>/wp-content/uploads/2010/04/featured-2-580x386.jpg) function.getimagesize: failed to open stream: no suitable wrapper could be found in /<snip>/wp-content/plugins/d13slideshow/d13slideshow.php on line 538 Is this a problem with the php setup or is there something I can do with the plugin or the function call from the template files to make it work? http://wordpress.org/extend/plugins/d13slideshow/

• Why check if your popoverController is nil? Doesn't Obj-C ignore messages to nil?

  - by Rob Fonseca-Ensor

  Pretty much everyone that writes about the UISplitView on the iPad uses the following code structure to dismiss a popover: if (popoverController != nil) { [popoverController dismissPopoverAnimated:YES]; } I though Objective-C was happy to ignore messages that are passed to nil? In fact, in the File New Project New Split View Application template, there's an example of this shortcut in the same code block (DetailsViewController.m): - (void)setDetailItem:(id)newDetailItem { if (detailItem != newDetailItem) { [detailItem release]; //might be nil detailItem = [newDetailItem retain]; // Update the view. [self configureView]; } if (popoverController != nil) { [popoverController dismissPopoverAnimated:YES]; //was checked for nil } } Why is that second if necessary?

• get xml attribute named xlink:href using xsl

  - by awe

  How can I get the value of an attribute called xlink:href of an xml node in xsl template? I have this xml node: <DCPType> <HTTP> <Get> <OnlineResource test="hello" xlink:href="http://localhost/wms/default.aspx" xmlns:xlink="http://www.w3.org/1999/xlink" xlink:type="simple" /> </Get> </HTTP> </DCPType> When I try the following xsl, I get an error saying "Prefix 'xlink' is not defined." : <xsl:value-of select="DCPType/HTTP/Get/OnlineResource/@xlink:href" /> When I try this simple attribute, it works: <xsl:value-of select="DCPType/HTTP/Get/OnlineResource/@test" />

• Generating code for service proxies

  - by Hadi Eskandari

  I'm trying to generate some additional code base on the auto-generated webservice proxies in my VS2010 solution, I'm using a T4 template to do so. The problem is, automatically generated proxies are added in "Service Reference" folder but ProjectItems (files) are hidden by default and the following code does not find them in the project structure: var sr = GetProjectItem(project, "Service References"); if(sr != null) { foreach(ProjectItem item in sr.ProjectItems) { foreach(var file in item.ProjectItems) { //Services.Add(new ServiceInfo { Name = file.Name }); } } } The above code runs and although service reference is found, and there are ProjectItems under that node (named by the webservice reference name), under object under that node is of type System.__ComObject and I'm not sure how to progress. Any help is appreciated.

• Puzzled with nib files...

  - by Michael

  I know nib files are serialized objects and they have owner, outlets to make connections. Using XCode Navigation window template I created application, which in its order created 2 nib files - MainWindow and SecondView. I can't understand how MainWindow is referring to SecondView, there is no connection between those two as far as I can see. SecondView's owner is UIViewController and in MainWindow there is a navigation tab which is also UIViewController. But how they are connected in IB I can't understand... Also I don't understand who is instanciating MainWindow's owner object and where that object is being kept, where is the variable which is UIApplication myApp = [[UIApplication alloc] init]. If I create 10 nib files with UIViewController owner, who will trigger their deserialization? If some class is nib file's owner, what is the essential responsibilities of that class? Is it deserializing nib file into memory? Sorry for unorganized questions, I've been reading numerous articles and docs about nib files, but it is still confusing.

• documenting black-box test cases

  - by Blux

  Hi everyone, I want to write an initial (black box) test cases for one of my university projects. I haven't started coding yet, I'm still in completing the SRS document and i should specify the test cases i'm going to implement after the coding. The project is web based, and i should follow this template in each test case: +++++ Test case ID: Author: Initial state: Preconditions: Use Case: Test input: Expected output: ++++++ The thing is, i don't know what is the difference between "initial state" and "preconditions". In some of the test cases it's hard to differentiate between them. Like in "Edit Page" what should be the initial state and what should be the preconditions? any help will appreciated.=)

• What causes a WPF ListCollectionView that uses custom sorting to re-sort its items?

  - by Drew Noakes

  Consider this code (type names genericised for the purposes of example): // Bound to ListBox.ItemsSource _items = new ObservableCollection<Item>(); // ...Items are added here ... // Specify custom IComparer for this collection view _itemsView = CollectionViewSource.GetDefaultView(_items) ((ListCollectionView)_itemsView).CustomSort = new ItemComparer(); When I set CustomSort, the collection is sorted as I expect. However I require the data to re-sort itself at runtime in response to the changing of the properties on Item. The Item class derives from INotifyPropertyChanged and I know that the property fires correctly as my data template updates the values on screen, only the sorting logic is not being called. I have also tried raising INotifyPropertyChanged.PropertyChanged passing an empty string, to see if a generic notification would cause the sorting to be initiated. No bananas. EDIT In response to Kent's suggestion I thought I'd point out that sorting the items using this has the same result, namely that the collection sorts once but does not re-sort as the data changes: _itemsView.SortDescriptions.Add( new SortDescription("PropertyName", ListSortDirection.Ascending));

• How to overcome an apparent REST vs. DRY dilemma in rails?

  - by Chris

  A rails app I'm working on features examples of quadratic equations. Obviously, these are all of a common structure: ax^2 + bx + c = 0. I don't want to store every single example of these. I'd rather generate them from a template. Storing hundreds of possible versions of this structure seems highly wasteful and un-DRY. On the other hand, if I generate them, I can't access them again reliably as I could if they were simply multiple database objects. I'm sure there must be a way to overcome this, but I'm still learning rails and I'm obviously not grasping something here. Thanks.

• Generalized plugable caching pattern?

  - by BCS

  Given that it's one of the hard things in computer science, does anyone know of a way to set up a plugable caching strategy? What I'm thinking of would allow me to write a program with minimal thought as to what needs to be cached (e.i. use some sort of boiler-plate, low/no cost pattern that compiles away to nothing anywhere I might want caching) and then when things are further along and I know where I need caching I can add it in without making invasive code changes. As an idea to the kind of solution I'm looking for; I'm working with the D programing language (but halfway sane C++ would be fine) and I like template.

• dompdf font family issue

  - by user335915

  Hello, I'm using Bamboo invoice as an invoice generator, and I'm trying to customize the invoice template, but no matter what I do, the font just won't seem to adjust. currently I have body { margin: 0.5in; font-family: 'helvetica'; font-size: 10pt;} I've read up on it, and helvetica is an installed font, so it should work to make sure I changed it to 'courier'; which is also in the lib/fonts directory, but the font remains the same. Any help? thanks in advance !

• Incorporate Wordpress into Kohana 3

  - by alex

  I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I can include a Wordpress blog within an existing Kohana application? Do you have any suggestions? Thanks Update Forgot to mention I have already programmed a model in Kohana to open pages based on their slug. Now I want to put blog content in there, and have the comments and other bits work. I also have installed WP e-Commerce and am wondering if there is any chance I can get that to work.

• SubSonic 3.0 - Save method with all columns as parameters?

  - by Todd Menier

  Hi, Just getting started with SubSonic. I'm using the Repository pattern, so my domain objects are totally seperate, and SubSonic-generated classes are used only in my data access layer. I'm wondering if a template exists that will give me a Save method (Insert/Update) that requires all table column values as parameters. My thinking is that since I need to do the mapping work manually, at least if my database schema changes (ie, a new column is added), I won't forget to add a corresponding mapping, since the auto-generated method signature would change and the compiler would catch it. I've considered messing with the T4 templates to add this feature, but thought I'd check if this already exists somewhere before I head down that path. Thanks in advance.

• How do you handle large repeated UI elements with JQuery

  - by jpoz

  Howdy, Here's the situation: You have a very complex UI element that is repeated in a list. Each has a menu on it, buttons, it hides and shows subelements, buttons for switch it's state, etc, etc. The elements are populated via JSON so you have to construct the elements and the functionality of the fly. What's the best way to accomplish this with JQuery? Where would you save the reusable template for the DOM structure? How would you add the behavior on? $().live? .livequery? onclick? manual after every JSON get? I guess I just see a lot of people doing different things. What's your experience with performance? Any insight would be much appreciated. Thanks, JPoz

• Code equivalence between Javascript and PHP

  - by xdevel2000

  I'm trying to learn PHP and I wish to know if there are some function equivalence constructs: In JS I can do: var t = function() {}; t(); myObj.DoStuff = function() {} // here I add a method at run-time myObj.DoStuff(); myObj["DoStuff"](); var j = myObj.DoStuff; j(); and so other things with function evaluation. In Js objects are associative arrays so every properties is accessible with the subscript notation... Can I add a method at run-time to a class template so next its object instances can have it? In JS I can do that via a prototype function property.

• Why would the assignment operator ever do something different than its matching constructor?

  - by Neil G

  I was reading some boost code, and came across this: inline sparse_vector &assign_temporary(sparse_vector &v) { swap(v); return *this; } template<class AE> inline sparse_vector &operator=(const sparse_vector<AE> &ae) { self_type temporary(ae); return assign_temporary(temporary); } It seems to be mapping all of the constructors to assignment operators. Great. But why did C++ ever opt to make them do different things? All I can think of is scoped_ptr?

• aspnet_regsql not working at all

  - by user252160

  I would like to create the ASP.NET User database template on a database of my own, because I'd like to fully untegrate the user system with the rest of my DB. As I've read, i needed to use the aspnet_regsql tool. I put all the options (because my database is running on SQLEXPRESS and is in an mdf file in my project's folder). the program starts and seemingly runs without any errors, however, when I open the database after that, not tables or stored procedures have been added. One more thing: I did one more test. I intentionally gave the -d option a wrong mdf file address, and surprisingly, the program "finished" correctly, yet no file was crated or modified whatsoever.

• How to insert into two different tables in one statement with Java and MySQL?

  I am using Java, Spring (NamedParameterJdbcTemplate) and MySQL. My statement looks like this: INSERT INTO Table1 (Name) VALUES (?); INSERT INTO Table2 (Path, Table1Id) VALUES (?, LAST_INSERT_ID()) But it is throwing the following error: PreparedStatementCallback; bad SQL grammar [INSERT INTO Table1 (Name) VALUES (?); INSERT INTO Table2 (Path, Table1Id) VALUES (?, LAST_INSERT_ID())] ` Nested exception is: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO Table2 (Path, Table1Id' at line 1 The syntax works fine in MySQL but something is up when combining via the Spring template. Thanks!

• Display archive posts in Wordpress

  - by missmonkee

  I am looking to display archives pages as a normal posts page... So, a posts page with a secondary navigation showing: Latest posts / Last month / Last year / Older On each of those pages, I would like to display a summary of each post just like the standard latest news page. When you click through you get to the full post. For each of menu items I have created seperate page templates such as archives_month.php, Then in the template instead of using For the LAST MONTH page. But I now cannot use this for LAST YEAR and OLDER posts. Can anyone help me? I've looked into a number of different ways to do it but on some blogs it's not clear and most people just retrieve a list of archives rather than displaying the posts. Thanks in advance. Mel

• How to implement a lazy loaded Silverlight data grid without using paging

  - by Marc Wittke

  Using the Business Application template from the brand new released RIA Services, you can see lots of examples using the data grid on top of a DomainDataSource in combination with a DataPager. The properties PageSize and LoadSize can be used to adjust the amount of data to be displayed in one page and the data that is prefetched in the background. Now I'd like to have a data grid with a scrollbar and no pager. The underlying DomainDataSource should load only the data that is diplayed in the grid. It should trigger another load, when the user scrolls down to items that are not yet in the data context. Is there any sample implementation how to do this?

• Get C# Templates For VS 2008 Shell

  - by Onorio Catenacci

  I've got VS 2008 Shell Integrated mode; I've got F# 2.0 on that installation. Till now this has worked fine for me because I've been hacking at F# code. Now though, I want to install Intellifactory's WebSharper. It looks like the Intellifactory templates assume that C# templates will be available because while it will create the F# portion of the solution it will not create the Web project in the solution with the complaint A problem was encountered creating the sub project 'Web Application'. The template specified cannot be found. Is there any place where I can get the C# stuff to add to this instance of VS 2008 Shell? Apologies in advance if this is a dup question but I've googled without much luck and I don't seem to find this here either. I've seen that about devenv /installvstemplates but that also fails with a message about needing to elevate privileges (which is odd since I try it under an admin user).
