• Can I assume Flash and PHP will generate the same floating point numbers?

  - by Fragsworth

  In a multiplayer game I'm developing, we have a few values that are floating point numbers. The back-end (in PHP) and the front-end (in Flash) occasionally perform the same calculations on these numbers, to minimize communication. I am currently making sure that both sides are using 64-bit doubles, but am I safe to assume that all calculations will be the same? For instance, what about string to float conversion - should I worry about Flash having a potentially different implementation as PHP? (If this happens, our game will go out of sync - the client will think it is in one state while the server is in another) With some testing, it appears to be the same, but I'm just not sure. Can someone clarify this for me?

• Recommendation for tool/framework that follows the naked objects pattern?

  - by Marcus Munzert

  I am searching for a tool/framework that follows the naked objects pattern and is written in Java. I know about tools like for instance JMatter, Naked Objects and Domain Object Explorer. That's not exactly what I am searching for, though. Open source would be great, but doesn't need to be. My intention is to use that tool/framework for the purpose of model-driven software development to do the modeling part. Ideally, such a tool/framework would provide the option to use JPA to store/load objects.

• Binding sub report in Crystal report

  - by Aijaz Chauhan

  Is it compulsory to bind sub report if we put sub report in main report ? here is my problem : code snippet : DataTable dtExtraDoc = dtDocSub.Select("DocumentId=14").Length == 0 ? null : dtDocSub.Select("DocumentId=14").CopyToDataTable(); if (dtExtraDoc != null && dtExtraDoc.Rows.Count > 0) { if (dtExtraDoc.Rows[0]["ResponceId"].ToString() == "2") { repdoc.Subreports["subRpt-extra-Doc-textile-claim-query-letter.rpt"].SetDataSource(dtExtraDoc); } } If dtExtraDoc is null then it will not bind the sub report and hence it gives me error " Object reference not set to an instance of object" I am totally new to crystal reports please help me.. Thanks in advance.

• How to extract messages to translate from a Play! application

  - by Martin

  I'm writing my first application using the Play! framework and I was wondering if there was a tool that could extract the messages that need translation from my views and controllers for me ? It is rather cumbersome to fill the conf/messages(.xx) file while I'm developing my app, but I'm afraid that if I don't do it as I go, I will never be able to completely translate my application afterwards. Such tools exist with other framework such as CakePHP for instance, and I think that it shouldn't be hard to write one by myself, but if there already is one... I was also wondering, what should I name the keys of the messages in my application ? Using gettext, it's not bad practice to directly type in the message in english as the key, but is it with the system that Play! uses (MessageFormat, right ?) ? Does anyone have an advice or naming convention (something like controller.action.describe_the_message maybe) ? Thank you for your advices !

• Ruby method Array#<< not updating the array in hash

  - by Mladen Jablanovic

  Inspired by http://stackoverflow.com/questions/2552363/how-can-i-marshal-a-hash-with-arrays I wonder what's the reason that Array#<< won't work properly in the following code: h = Hash.new{Array.new} #=> {} h[0] #=> [] h[0] << 'a' #=> ["a"] h[0] #=> [] # why?! h[0] += ['a'] #=> ["a"] h[0] #=> ["a"] # as expected Does it have to do with the fact that << changes the array in-place, while Array#+ creates a new instance?

• C++ and C#, "Casting" Functions to Delegates, What's the scoop?

  - by Jacob G

  In C# 2.0, I can do the following: public class MyClass { delegate void MyDelegate(int myParam); public MyClass(OtherObject obj) { //THIS IS THE IMPORTANT PART obj.SomeCollection.Add((MyDelegate)MyFunction); } private void MyFunction(int myParam); { //... } } Trying to implement the same thing in C++, it appears I have to do: MyDelegate del = gcnew MyDelegate(this, MyFunction); obj-SomeCollection-Add(del); Obviously I can create a new instance of the delegate in C# as well instead of what's going on up there. Is there some kind of magic going on in the C# world that doesn't exist in C++ that allows that cast to work? Some kind of magic anonymous delegate? Thanks.

• Alternatives to UIWebView for rich content?

  - by ojreadmore

  In my app, I am displaying 4 "tabs", each are local content through a UIWebView. I create HTML markup from my simple data. This is slow to load and I'm trying to speed it up. I'm using UIWebView to accomplish these: 1. hyperlinks 2. some styling - font colors 3. HTML tables Writing my own class to handle this is okay for (1.) hyperlinks - I can use a touch event to call a method. And (2.) styling - I can use UILables to do basic formatting, no biggie here. BUT what I really love about the UIWebViews is the (3.) HTML tables! I find it troublesome to line up the UILabels in a way that mimics HTML Tables, for instance, one cell's height in a row changes the height of all cells. I'm looking for another perspective or knowledge of an alternative.

• Adding a new row in between rows in a grid view.

  - by SARAVAN

  I have an ASP .net grid view. It has some template columns like a command button, a text box, and a dropdown control. When I click the command button, a new row needs to be inserted below the current row (from where I hit the command button). If I have rows 1 and 2 and I hit the command button in row1 a new row needs to be inserted between rows 1 and 2 Now in the new row I should be able to select values from dropdown and enter some value in a text box and finally hit my save button. (Which should work fine as I am expecting) The grid view is bound to some data source say for instance a datatable for now. Oneway that I could think about is when Command button is clicked, I can add a new row to the datatable in my server side code and rebind the grid. But I am not sure that, from a UI perspective how I can make sure that the new row goes exactly below the row from where I hit the command button. Any thoughts or comments?

• How to write custom SQLite functions in Javascript inside a Webkit browser?

  - by Jay Godse

  I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?

• Authenticating a user for a single app with multiple domains

  - by hofnarwillie

  I have one asp.net web application, but two different domains point to this web app. For instance: www.one.com and www.two.com both point to the same web app. I have an issue where I need certain pages to be on a specific domain (due to some security requirements from our online payment provider - a third party website). So let's say page1.aspx needs to be called on www.two.com The process is as follows: A user logs into www.one.com The authentication cookie is saved to the browser The user then navigates to page1.aspx and, if on the wrong domain, gets redirected to the correct domain. (this redirection happens on page1.aspx in the page_load event) Then asp.net redirects the user to the login screen, because the authentication cookie is not sent to www.two.com. How can I track the user and keep him/her logged in between the two domains?

• Input checkbox name converts period signs into underlines on post

  - by Rakoon

  Hello I am working on an image gallery at the moment. When a user is logged in, an x appears over each image and a checkbox next to it to enable the user to delete that image. Only if the checkbox is checked will the image be deleted. They are both in a (one for each image in the gallery), the small image "x.gif" is an input type="image" that submits the $_POST form. The checkbox inherits the name of the image and is to prevent accidentally pressing the x button and deleting an image. The problem is that the checkbox name, upon posting it gets converted from (for instance) "Image.jpg" to "Image_jpg" When i test it with print_r($_POST); Should I create code for replacing _jpg or _gif into .jpg and .gif after the post or is there a way to make it possible to use period signs in input names? Any help is greatly appreciated.

• Re-ordering a collection of UIView's based on their CGPoint

  - by Chris

  Hi all, I have a NSMutableArray that holds a collection of UIViewControllers Amongst other properties and methods an instance of each of the viewControllers are placed in a parent view The user will place these objects individually when desired to. So essentially I use - (void)addSubview:(UIView *)view when a new view is added to the parent view controller. Because the UI is isometric it's made things a tad more complicated What I am trying to do is re-order the views based on their co-ordinate position, so items higher up the parent UIView frame is indexed lower then views lower in the parent UIview frame. And items that are on the left side of the view are positioned at a higher index to those on the right I think the solution may have to do with re-ordering the NSMutableArray but how can I compare the CGpoints? Do I need to compare the x and y separately?

• Which .NET exception to throw for invalid database state?

  - by jslatts

  I am writing some data access code and I want to check for potentially "invalid" data states in the database. For instance, I am returning a widget out of the database and I only expect one. If I get two, I want to throw an exception. Even though referential integrity should prevent this from occurring, I do not want to depend on the DBAs never changing the schema. I would like to use the System.IO.InvalidDataException, except that I am not dealing with a file stream so it would be misleading. I ended up going with a generic applicationexception. Anyone have a better idea?

• [PHP] Processing custom XML namespace within XSL

  - by sander

  I'm using the php class XSLTProcessor to generate HTML from a xsl. Within the xsl, I'd like all my custom namespace elements to be processed by my own processor class. So for example: <xsl:for-each select="doc/elements/*"> <doc:renderElement element="." /> </xsl:for-each> This should call the method renderElement of an instance of my custom processor class. I know I can enable calling php functions by using the registerPHPFunctions function. However, this only seems to support calling static methods.

• How to default-initialize local variables of built-in types in C++?

  - by sharptooth

  How do I default-initialize a local variable of primitive type in C++? For example if a have a typedef: typedef unsigned char boolean;//that's Microsoft RPC runtime typedef I'd like to change the following line: boolean variable = 0; //initialize to some value to ensure reproduceable behavior retrieveValue( &variable ); // do actual job into something that would automagically default-initialize the variable - I don't need to assign a specific value to it, but instead I only need it to be intialized to the same value each time the program runs - the same stuff as with a constructor initializer list where I can have: struct Struct { int Value; Struct() : Value() {} }; and the Struct::Value will be default-initialized to the same value every time an instance is cinstructed, but I never write the actual value in the code. How can I get the same behavior for local variables?

• Test-driven Development: Writing tests for private / protected variables

  - by Chetan

  I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

• What's a good algorithm for searching arrays N and M, in order to find elements in N that also exist

  - by GenTiradentes

  I have two arrays, N and M. they are both arbitrarily sized, though N is usually smaller than M. I want to find out what elements in N also exist in M, in the fastest way possible. To give you an example of one possible instance of the program, N is an array 12 units in size, and M is an array 1,000 units in size. I want to find which elements in N also exist in M. (There may not be any matches.) The more parallel the solution, the better. I used to use a hash map for this, but it's not quite as efficient as I'd like it to be. Typing this out, I just thought of running a binary search of M on sizeof(N) independent threads. (Using CUDA) I'll see how this works, though other suggestions are welcome.

• Unique constraint on more than 10 columns

  - by tk

  I have a time-series simulation model which has more than 10 input variables. The number of distinct simulation instances would be more than 1 million, and each simulation instance generates a few output rows every day. To save the simulation result in a relational database, i designed tables like this. Table SimulationModel { simul_id : integer (primary key), input0 : string or numeric, input1 : string or numeric, ...} Table SimulationOutput { dt : DateTime (primary key), simul_id : integer (primary key), output0 : numeric, ...} My question is, is it fine to put an unique constraint on all of the input columns of SimulationModel table? If it is not a good idea, then what kind of other options do i have to make sure each model is unique?

• In PHP + MySQL, How do I join many tables with conditions

  - by Moe

  Hi, I'm trying to get the users full activity throughout the website. I need to Join many tables throughout the database, with that condition that it is one user. What I currently have written is: SELECT * FROM comments AS c JOIN rphotos AS r ON c.userID = r.userID AND c.userID = '$defineUserID'; But What it is returning is everything about the user, but it repeats rows. For instance, for one user he has 6 photos and 5 comments So I expect the join to return 11 rows. Instead it returns 30 results like so: PhotoID = 1; CommentID = 1; PhotoID = 1; CommentID = 2; PhotoID = 1; CommentID = 3; and so on... What am i doing wrong?

• Access of private field of another object in copy constructors - Really a problem?

  - by DR

  In my Java application I have some copy-constructors like this public MyClass(MyClass src) { this.field1 = src.field1; this.field2 = src.field2; this.field3 = src.field3; ... } Now Netbeans 6.9 warns about this and I wonder what is wrong with this code? My concerns: Using the getters might introduce unwanted side-effects. The new object might no longer be considered a copy of the original. If it is recommended using the getters, wouldn't it be more consistent if one would use setters for the new instance as well?

• Getting 0x80131902 when calling COM+ component

  - by Kyle W

  I created a COM+ component in .Net. It needs to use a configuration file, so I've created a directory with an application.manifest and application.config file and set that as the Application Root Directory. Now when I try to create an instance of that object, I get the following HRESULT: 0x80131902. I can't seem to find exactly what this means, except that there is a problem loading the app-domain. If I don't set the Application Root Directory, it loads just fine (but doesn't have access to the config).
