  • Binding a single array cell to a WPF control

    - by yomi
    Hi, I have a bool array of size 4 and I want to bind each cell to a different control. This bool array represents 4 statuses (false = failure, true = success). This bool array is a propery with a class: class foo : INotifyPropertyChanged { ... private bool[] _Statuses; public bool[] Statuses { get {return Statuses;} set { Statuses = value; OnPropertyChanged("Statuses"); } } In XAML there are 4 controls, each one bound to one cell of the array: ... Text="{Binding Path=Statuses[0]}" ... ... Text="{Binding Path=Statuses[1]}" ... ... Text="{Binding Path=Statuses[2]}" ... ... Text="{Binding Path=Statuses[3]}" ... The problem is that the notify event is raised only when I change the array itself and isn't raised when I change one value within the array, i.e, next code line raises the event: Statuses = new bool[4]; but next line does not raises the event: Statuses [0] = true; How can I raise the event each time one cell is changed?

  • Update single field

    - by 47
    I have a Customer class which has a representative field....this field is initially blank but when the user opens up the details page of the chosen customer, they'll be given the open of representing this customer by clicking on a link. The template layout I was thinking of is this: <strong>Representative: </strong> {% if customer.representative %} {{ customer.representative }} {% else %} <a href="{% url representCustomer customer.id %}">Represent this customer.</a> {% endif %} All that remains is the view to effect this...this is where I'm stuck.

  • visual tool to resolve conflicts merged into a single file

    - by Yehosef
    I did a git merge and ended up with a file like that looks like this: class member extends item{ /********CONSTANTS**********/ const is_flaggable = true; const is_commentable = false; const is_ratable = false; const table = 'member'; <<<<<<< HEAD const table_about = 'mem_about' ; const table_to_about = 'mem_to_about' ; const table_hobbies = 'mem_to_hobby'; ======= const table_friendship = 'friendship'; const table_about = 'mem_about' ; const table_to_about = 'mem_to_about' ; const table_hobbies = 'mem_to_hobby'; const table_friendship_id = 3; >>>>>>> my-copy In this file there are many blocks like this. Is there a visual tool to help me look at this file and pick and choose the changes I want? Most of the diff tools I found are for looking at two files.

  • Conversion of Single to two UInt16 values in .net

    - by Gio
    In the good old days of C. I could cast a float to an int (assuming 32 bit system), do some bit manipluation ( bitwise and, right shift, ect ), and get the upper and lower 16 bit hex representations of the floating point number, which I could then store in two short values. I'm not seeing an easy way of doing this in C#. System.Convert.ToUInt16 just does a float to int convert (even after I shift right), which leaves a vlaue of 0 if the float is less than 0, which is not the desired effect. //useless leaves me witg a value 0f 0 UIN16 s1 = (UInt16)((System.Convert.ToUInt32(d2) & 0xffff0000) >> 16); //capture the high word UInt16 s2 = (UInt16)(System.Convert.ToUInt32(d2) & 0xffff); //capture the low word A basic cast (UInt32) doesn't work either.

  • Include Obj-C++ header from C++ source file

    - by Schwitzgabel
    Consider the followng situation: MacFont.h struct MacFont : Font { // ... NSFont* font; }; MacFont will be implemented in MacFont.mm FontEngine.cpp: #if defined(OS_MAC) #include "MacFont.h" #elif // ... #endif //... In order to make it compiling, I should rename FontEngine.cpp to FontEngine.mm but I'm not allowed to. So what now?

  • Injecting single-use object into class

    - by moteutsch
    I have the following code: <?php class X { public function do($url) { $httpRequest = new \HttpRequest\Curl($url, $this->getOptions()); $httpRequest->fire(); // etc. } // ... } In order to be able to unit test this class, I'd like to inject a mocked HttpRequest class. One way to do this would be as follows: <?php class X { private $httpRequestClass; public function __construct($httpRequestClass = '\HttpRequest\Curl') { $this->httpRequestClass = $httpRequestClass; } public function do($url) { $httpRequest = new $this->httpRequestClass($url, $this->getOptions()); $httpRequest->fire(); // etc. } // ... } But this doesn't seem right. Any other ideas?

  • creating a static vb.net "app" that consist of a single picture

    - by michael
    I need to create a vb.net program that consists of a unmovable, always on top bitmap, with no menu bar or anything, and does not show up in the task bar as program. It needs to always start in the same place. Essentially I need to mask a part of the screen by using a bitmap that blends into the scenery. I am not sure which properties I need to tweak to achieve all of this.

  • Multiple controllers with a single model

    - by Eric K
    I'm setting up a directory application for which I need to have two separate interfaces for the same Users table. Basically, administrators use the Users controller and views to list, edit, and add users, while non-admins need a separate interface which lists users in a completely different manner. To do this, would I be able to just set up another controller with different views but which accesses the Users model? Sorry if this is a simple question, but I've had a hard time finding how to do this.

  • Selecting two specific mysql table rows in a single query

    - by Scotta
    Lets say I have a table with 20 entries. They are sorted by date (date is a column name _) in descending order. How would I go about selecting ONLY the newest entry and the 15th oldest entry? I am getting all 15 results by doing the following query SELECT * FROM mytable m WHERE col1 = "zzz" ORDER BY date DESC LIMIT 15;

  • Rails - single ID for multiple models

    - by user352351
    I'm building an app which will allow a user to scan the barcode on a 'shelf', 'box' or 'product' which will then bring up that particular item or all the associated items. As these are all separate models with their own ID's, I need a global ID table. I was thinking of a polymorphic table called 'barcodes' barcodes id barcode_number barcodable Is there an easy way to do this? Or is polymorphic the best way?

  • Django: Converting an entire Model into a single dictionary

    - by LarrikJ
    Is there a good way in Django to convert an entire model to a dictionary? I mean, like this: class DictModel(models.Model): key = models.CharField(20) value = models.CharField(200) DictModel.objects.all().to_dict() ... with the result being a dictionary with the key/value pairs made up of records in the Model? Has anyone else seen this as being useful for them? Thanks. Update I just wanted to add is that my ultimate goal is to be able to do a simple variable lookup inside a Template. Something like: {{ DictModel.exampleKey }} With a result of DictModel.objects.get(key__exact=exampleKey).value Overall, though, you guys have really surprised me with how helpful allof your responses are, and how different the ways to approach it can be. Thanks a lot.

  • Can single-buffer blocking WSASend deliver partial data?

    - by CodeAngry
    I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

  • Considerations when porting a MS VC++ program (single machine) to a rocks cluster

    - by Mel
    I am trying to port a MS VC++ program to run on a rocks cluster! I am not very good with linux but I am eager to learn and I imagine porting it wouldn't be an impossible task for me. However, I do not understand how to take advantage of the cluster nodes. because it seems that the code execute only runs on the front end server (obviously). I have read a little about MPI and its seems like I should use MPI to comminicate between nodes. The program is currently written such that I have a main thread that synchronizes all worker threads. The main thread also recieves commands to manipulate the simulation or query its state. If the simulation is properly setup, communication between executing threads can be significantly minimized. What I don't understand is how do I start the process on the compute nodes and how do I handle failures in nodes? And maybe there should be other things I should also consider when porting my program to run in a cluster?

  • writing a single line of a file in C++ into two different arrays

    - by mekasperasky
    suppose a text file has 11001100 11001101 and i open the text file and take the input from the file as pt[0]=11001100, pt[1]=11001101.. but if i take the input from file as inpt it wont put it in two different arrays which is obvious but it takes the whole line . Thus I have to take another for loop and traverse through the whole string and when I find a null character i start putting into the second array . But how can I do it without putting it into a variable and traversing .. I mean directly from the file itself ..

    I'm trying to set up a test project looking like my own project just to get things working first and it looks like this: /MainProject/inc/main.h /MainProject/src/main.cpp /LibProject/inc/test.h /LibProject/src/test.cpp I've found some tutorials, but I cant find out how to set up this when I have the inc and src folder? How would the CMakeLists.txt files look? Would I have one in /, one in each of the project folders? It seems like I dont need to have one in the inc and src folders?
