  • Automatically selecting and creating class objects

    - by Omin
    Lets say that we have a box class: class Box { private int width; private int height; //Box Constructor public Box( int height ) { this.height = height; width = 450; } } and a series of Box objects in our main: Box Box1 = new Box(147); Box Box2 = new Box(178); Box Box3 = new Box(784); Is there a way to use a "for" loop to go through these objects? Also, how would you make the computer create class objects for us? eg. create 10 objects using: for( int i=0; i>10; i++) { //method }

  • Which method should I use to give the perception the computer is thinking in programming?

    - by Roy
    I want to create a simple game like tic tac toe where the human user is playing against the computer. The computer function takes a couple of milliseconds to run but I would like to make the computer take 5 seconds to make a move. Which method should I use? 1) Create two memory threads. One for the computer and one for the human user. When the computer is taking 5 seconds to imitate thinking, the human user thread is paused for 5 seconds. 2) Disable input devices for 5 seconds using timer or dispatchertimer 3) Any better methods you can think of Thanks!

  • Storing string in CStatic

    - by Shark
    I have to create dynamically allocated array of CStatic (CStatic* array;), which then displayed on the dialog. It must be allocated and filled like this: array = new CStatic[list_box.GetCount()]; for (int i = 0; i < list_box.GetCount(); i++) { CString str; list_box.GetText(i, str); array[i].Create(str, WS_CHILD, CRect(), GetParent()); } But str is destroyed after the dialog is closed, because list_box destroyes too, and all pointers inside CStatics points nowhere (I assume it is not working because of this). What can I do to fix this? Any help would be appreciated. P.S. I know, that this is awful way and this is all wrong and I know how to do this right, but unfortunately, I can't change tasks, they give us in the university :)

  • Why is $file empty in custom symfony file validator?

    - by codecowboy
    I am setting a custom file validator for a file input field in Symfony 1.4 (Doctrine) $this-setValidator('filename', new sfValidatorFile(array( 'mime_types' = 'web_images', 'path' = sfConfig::get('sf_upload_dir').'/animals', 'validated_file_class' = 'CustomValidatedFile', 'required' =false ))); I then want to override the save method to generate some thumbnails: class CustomValidatedFile extends sfValidatedFile { private $savedFilename; // Override sfValidatedFile's save method public function save($file = null, $fileMode = 0666, $create = true, $dirMode = 0777) { $this-savedFilename = $this-generateFilename(); // This makes sure we use only one savedFilename (it will be the first) if ($this-savedFilename === null ) { $this-savedFilename = $file; } $thumbnail = new sfThumbnail(150,150); $thumbnail-loadFile($this-getTempName()); $thumbnail-save(sfConfig::get('sf_upload_dir').'/thumbnails/thumb_'.$this-savedFilename); // Let the original save method do its magic :) return parent::save($this->savedFilename, $fileMode, $create, $dirMode); } } This fails with the error "The file "" is not readable." This is coming from sfThumbnailPlugin because the value of $file is null. My question is why is $file null?

  • How do you reference another element in a xaml list

    - by Ball
    I'm using xaml as a datastore because It's quick and we haven't yet defined a file format. But I can only seem to create xaml that is a pure tree, even if it is acyclic. I know how to create a list of items in xaml, but How do I share objects in two lists? Below is an example of what I'm trying to say. <CreaturFile> <CreatureFile.Monsters> <Monster Name="Kobold" x:Name="Mepo"/> <Monster Name="Goblin"/> </CreatureFile.Monsters> <CreatureFile.Encounters> <Encounter> <Reference ElementName="Mepo"/> </Encounter> </CreatureFile.Encounters> </CreatureFile>

  • How do I add to a model when on the Show of another model?

    - by Angela
    I on the Show of "Contacts" and want, from that page, to submit a Comment that is related to the Contact. The way I understand to do it would be: <%= start_form_tag :action => "add_comment", :id => @contact %> <% text_area "comment, "body", "rows" = > 5 %> <br> <%= submit_tag %> <%= end_form_tag %> I would create a method in the Contacts controller: def add_comment Contact.find(params[:id]).comments.create(params[:comment]) end However, I feel there's a better way, but don't know what that is? I learned this on a pretty outdated book. Basically, I want to add a new object belonging to a Model while on the Show of a different Model. Would formtastic help me, and if so, how?

  • Workflow Foundation: Asynchronous operations (lengthy network I/O)

    - by StormianRootSolver
    I have to create an application that will be started a few times per day (it's non - interactive). To operate, it needs LARGE amounts of data from the Internet (megabytes) via a rather slow connection, so the WCF service calls take quite some time. At the same time, it needs to perform local calculations and has a sophisticated initialization process. So, what I want to do is to create a workflow that asynchronously fetches the data (takes a few minutes) while already initializing / calculating locally. Is there a way to accomplish this?

  • Copy Rows in a One to Many with LINQ to SQL

    - by Refracted Paladin
    I have a table that stores a bunch of diagnosis for a single plan. When the users create a new plan I need to copy over all existing diagnosis's as well. I had thought to try the below but this is obviously not correct. I am guessing that I will need to loop through my oldDiagnosis part, but how? Thanks! My Attempt so far... public static void CopyPlanDiagnosis(int newPlanID, int oldPlanID) { using (var context = McpDataContext.Create()) { var oldDiagnosis = from planDiagnosi in context.tblPlanDiagnosis where planDiagnosi.PlanID == oldPlanID select planDiagnosi; var newDiagnosis = new tblPlanDiagnosi { PlanID = newPlanID, DiagnosisCueID = oldDiagnosis.DiagnosisCueID, DiagnosisOther = oldDiagnosis.DiagnosisOther, AdditionalInfo = oldDiagnosis.AdditionalInfo, rowguid = Guid.NewGuid() }; context.tblPlanDiagnosis.InsertOnSubmit(newDiagnosis); context.SubmitChanges(); } }

  • Dynamic name of NSMutableDictionary?

    - by Bruno
    Hi everyone I load from a txt file many info, and I would like, if possible, to dynamically create NSmutable dictionary with the elements of the txt. For example, each is like that: id of element | date | text What I'm asking is the equivalent of the NSString stringWithFormat:. Can we do the same for an Mutable Dictionary? To be more practical, let's say the NSString *date is equal to "23/12/2009" (for europe). I want to create a dictionary called 23/12/2009 without declaring *23/12/2009 but just something like dictionaryWithFormat: @"%@", date]; I'm stuck on this, and I don't even know if it is possible. If not, what's the best way to approach that? Thanks everyone Regards

  • how rspec creates database between specs

    - by timpone
    This is a bit of a naive / simple question. I'm having a hard time finding this info online. Basically, does rspec run rake db:test:prepare between every rspec group? Or is it between every example or model? Or does the schema get loaded once and then truncated between each. I need to add a rake task directly after this call to create a view since they are not supported in schema.rb. Either a link or explanation would be greatly appreciated so that I know where to insert my rake task to create a view. Or whether there is a callback like rake db:test:after_prepare thx

  • RSpec setup for an application that depends on an external database from another application.

    - by Chris Rittersdorf
    I've had to add features to an application that depends on a database from another application. I've been able to set up a connection to this external database and pull data from it. However, I'm not sure how to get my main application to create a test database for this external application. It would be awesome if there some way to pull in the schema for this database and create it in the same manner that 'rake db:test:prepare' does. Is there any configuration capabilities for RSpec to do this, or will I have to roll my own task?

  • Issue with storing items in session in MVC

    - by Sundeep
    I have a customer page on which user can enter multiple locations for customer. I am using telerik ajax grid to display locations, and when a new location is added, I am adding it to session and returning back to the grid. Finally, when user submits, customer and all locations using customerid as reference key gets inserted. I am clearing the session, when user enters create/edit page and on successful commit or any exception occurs. Problem is when user adds the locations for one user and then opens another tab, to create another user then all locations get cleared for previous user. Coz of session, this issue is occuring. Something of viewstate would be page specific. But for ajax grid actions, viewdata/viewbag is not working. Any thoughts on how to implement this. Thanks in advance.

  • SQL Server 2008 vs 2005 udf xml perfomance problem.

    - by user344495
    Ok we have a simple udf that takes a XML integer list and returns a table: CREATE FUNCTION [dbo].[udfParseXmlListOfInt] ( @ItemListXml XML (dbo.xsdListOfInteger) ) RETURNS TABLE AS RETURN ( --- parses the XML and returns it as an int table --- SELECT ListItems.ID.value('.','INT') AS KeyValue FROM @ItemListXml.nodes('//list/item') AS ListItems(ID) ) In a stored procedure we create a temp table using this UDF INSERT INTO @JobTable (JobNumber, JobSchedID, JobBatID, StoreID, CustID, CustDivID, BatchStartDate, BatchEndDate, UnavailableFrom) SELECT JOB.JobNumber, JOB.JobSchedID, ISNULL(JOB.JobBatID,0), STO.StoreID, STO.CustID, ISNULL(STO.CustDivID,0), AVL.StartDate, AVL.EndDate, ISNULL(AVL.StartDate, DATEADD(day, -8, GETDATE())) FROM dbo.udfParseXmlListOfInt(@JobNumberList) TMP INNER JOIN dbo.JobSchedule JOB ON (JOB.JobNumber = TMP.KeyValue) INNER JOIN dbo.Store STO ON (STO.StoreID = JOB.StoreID) INNER JOIN dbo.JobSchedEvent EVT ON (EVT.JobSchedID = JOB.JobSchedID AND EVT.IsPrimary = 1) LEFT OUTER JOIN dbo.Availability AVL ON (AVL.AvailTypID = 5 AND AVL.RowID = JOB.JobBatID) ORDER BY JOB.JobSchedID; For a simple list of 10 JobNumbers in SQL2005 this returns in less than 1 second, in 2008 this run against the exact same data returns in 7 min. This is on a much faster machine with more memory. Any ideas?

  • Automation for filling in sets of numbers in each row

    - by Brad
    I need to populate the same number 10 times in a row, then the next number up on the next row. starting at 0, ending at 1000 for example: 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3 3 .... 1000 1000 1000 1000 1000 and to 1000 I need to print out these numbers to cut up and put each row of numbers in each envelope to be sold for a Chinese auction at a benefit. How do I do this dynamically without entering in all of the rows by hand?

  • Best Ruby ORM for Wrapping around Legacy MSSQL Database?

    - by Technocrat
    Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support mssql through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in MSSQL. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the MSSQL app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with MSSQL but never to do anything quite like this. Any suggestions?

  • Making Thunderbird auto-add SMTP identities whenever I reply

    - by 0xC0000022L
    How can I teach Thunderbird to automatically add an SMTP identity whenever I reply to an email directed to <whatever>@<mydomain>? So if an SMTP is configured for <mydomain> but no identity exists for <whatever>@<mydomain>, how can I make Thunderbird dynamically recognize this and add it. Currently I have to manually add the identity every single time, but I would prefer it to to be added ad-hoc. As long as Thunderbird was configured to know about the SMTP serving <mydomain> this should be trivial, but I couldn't find an option. An add-on or something like a catch-all/wildcard identity would also do as long as it doesn't require manually setting up a new identity every time.

  • How to change the app name in OSX menubar in a pure-Python application bundle?

    - by gyim
    I am trying to create a pure-Python application bundle for a wxPython app. I created the .app directory with the files described in Apple docs, with an Info.plist file etc. The only difference between a "normal" app and this bundle is that the entry point (CFBundleExecutable) is a script which starts with the following line: #!/usr/bin/env python2.5 Everything works fine except that the application name in the OSX menubar is still "Python" although I have set the CFBundleName in Info.plist (I copied the result of py2app, actually). The full Info.plist can be viewed here: http://tinyurl.com/32qgpjt How can I change this? I have read everywhere that the menubar name is only determined by CFBundleName. How is it possible that the Python interpreter can change this in runtime? Note: I was using py2app before, but the result was too large (50 MB instead of the current 100KB) and it was not even portable between Leopard and Snow Leopard... so it seems to be much easier to create a pure-Python app bundle "by hand" than transforming the output of py2app.

  • jquery custom drag and drop

    - by samlochner
    I am trying to create functionality similar to drag and drop. I need to create my own as there will be some significant differences to the drag and drop in the jquery UI. I would like to have mousemove being called repeatedly at all times, and mousedown called every time the mouse is pressed. So I have the following code: $(document).bind('mousemove',function(e){ $("#coords").text("e.pageX: " + e.pageX + ", e.pageY: " + e.pageY); }); $(document).bind('mousedown',function(e){ }); ('coords' is the id of a div) As I move the mouse, coordinates are reported correctly in 'coords'. If I depress a mouse button and then move the mouse, coordinates are still reported correctly. But if I depress a mouse button on an image and then move the mouse, coordinates are reported correctly for a few sets, and then they seize up! Why is this happening and how can I fix it? Thanks, Sam
