I am trying to bind an element from the view to a matrix in the view model. In the binding I want to use indexers so I can retrieve the element that I want. The following syntax does not work:
Fill="{Binding OwnBoard[0\,0], Converter={StaticResource BoardToBackConv}}"
If I remove the indexers, the binding is done and I get the value of the OwnBoard Property in the converter, but once I add the indexer, this does not work anymore and the converter is never called.
Do you know why this does not work in Windows Phone 8?
Unfortunately, it looks like two-dimensional indexers aren't supported in Silverlight (Windows Phone .net apps are based on Silverlight): http://msdn.microsoft.com/en-us/library/cc645024(v=vs.95).aspx/html#indexdata
Only one-dimensional array indexing is supported.
As a workaround I would suggest to use a converter, but since you're already using one you'd have to find a way to chain two converters.

In our implementation of the Rules Engine we have a test form similar to Rule Test Form on the online demo on "Business Rules Engine Demo". What we would like to do is conditionally show only the Test Fields for the items in use in the rule. We are doing this by grabbing the rule.definition JSON from the ruleeditor then look for the items which we can conditionally create using AngularJS's ng-if directive. This works great with Fields. If the user selects a method, our method of parsing the string is failing. What it appears is the Field Names are stored in the JSON as plain text however the Method Names are not. Is there a way we can configure the control to either A not encrypt the method names or is there a way that we can tap into the encryption to identify if a method is in use in our rule? Thanks in advance.
Methods and actions can have overloads which the Code Effects rule editor supports. Therefore, we can't have multiple menu entries with the same name. Instead, we use a signature hash on all in-rule methods and rule actions regardless of whether it has an overload or not to make them unique on the client.
You need to have either the Full Source or the Editor Source license in order to change the code to either stop that hashing, or tap into the process, or implement it your own way. You don't have that option with any other Code Effects perpetual license.
I'am testing the new Core Sportlight API feature in iOS 9. The indexing process works well but is there a way to define that the indexed Item should only get searched by the "title" Attribute instead of "title" and "description"?
Maybe you already have some more informations than me.
I have tried doing this using Objective C, and it works perfectly.
It depends on what implementation of "CSSearchableAttributeSet" is used.
In obj C, there are many implementations of CSSearchableAttributeSet like
CSSearchableItemAttributeSet_General
CSSearchableItemAttributeSet_Document
CSSearchableItemAttributeSet_Image
and others.
I have used CSSearchableItemAttributeSet_General in my code and I'm able to search by the title attribute only. In fact, that particular implementation of CSSearchableItemAttributeSet doesn't even have a "description" attribute.
So depending on what type of object you want to search for, you can use the particular implementation.
I believe it would be the same equivalent class in swift as well.

While using C++ I have to deal with programs that have objects like matrices, linked lists etc
The default view of eclipse for variables while debugging is not very useful. It normally shows pointer values with value of only the first element in the array.
Below is how it is in eclipse:
As we can see the matrix object has rows and columns integers and a double 2D array. I cannot see the values of the array in user friendly manner.
My question is that, is there anyway in eclipse (using plugin etc) through which I can define custom user interfaces (popups) for each object/class of my interest.
For example I would like to have the following (Matlab's view) kind of popup when I hover over an initialized matrix object:
The JDT has a feature called detail formatters to make that possible. The corresponding implementation for the CDT seems to have stalled after a first prototype however, and did not make it into Eclipse.
Is there any way I can use the format_number_choice function inside of a actions file. In fact I need to use it for a Form error message.
'max_size' => 'File is too large (maximum is %max_size% bytes).',
In English it's simply "bytes", but in other languages the syntax changes after a certain value (for example if the number is greater than 20 it's: "20 of bytes").
I can use parenthesis, of course, but if the framework offers support for doing this specific thing, why not to use it?!
The way it's currently implemented in the 1.4 branch, you can define only one translation per message using il18n XML files.
What you could do is create a custom validator which inherits the current validator (sfValidatorFile in your example) and does the size checking in the doClean method before calling its parent's method.
I suggest you take a look at the source to see how it works : sfValidatorFile
The correct way to handle number ranges for translation is explained here in the Definitive Guide. I won't reproduce it here as the documentation itself is clear and concise. Note however that the string is not extracted automatically by the i18n-extract task, so you need to add it manually - again, the documentation explains this.
So yes, you can use the format_number_choice() function inside an action - you just need to load the helper inside the action like this:
sfContext::getInstance()->getConfiguration()->loadHelpers('I18N');
I have a custom node type for which I want to have a field that uses a special combobox based on list_text. When one chooses the type list_text it is normally possible to enter a static list of selectable texts, however, I want this list to be dynamic, i.e. based on the results of a db_query. What is the best way to do this using Drupal 7?
A simple example for clarification: A node of this custom type X contains a field that points to another node, so whenever a node of type X is created I want a combobox that contains all other nodes.
(Best solution would be to only display the combobox during node creation, and no longer during edit. But I could also live with it if the combobox was shown during the edit as well.)
I have tried to customize options_select by defining my own data type and implementing hook_options_list accordingly. The combobox was displayed during creation with the correct values, however, I could not save it.. I have no idea what went wrong there, but on the first submit it would change to a different theme, and when I tried again I got an internal server error. Am I on the right track at all with defining a completely new data type for the field? there surely must be a simpler way?
You're right in that you don't need a new datatype. Here's a good tutorial on how to do this. It's not specifically for D7 but I didn't see much that wasn't still applicable. There may be a better way to do it in D7 specifically but I would love to know it too if so :)
The tutorial linked by allegroconmolto sent me on the right way. Thanks for that.
Here's the simpler way of doing it: tutorial
Basically, it is, as I assumed, a common problem and hence a simple solution for it was included in the webform module by now. It provides a hook_webform_select_options_info which can be used to register a callback method. The callback method is then called each time a corresponding option select of a webform is shown, so that you can easily fill it with the results of a dbquery or anything else. Works like a charm and takes next to no time to implement.
