• Stage shifts when using addChild?

  - by josh

  I'm having a very odd bug with ActionScript 3 in Flash CS4. I am adding movie clips to a stage in a for loop and then moving them out of view so that I can pull them in and remove them when I need them. I've narrowed down the issue to a point that I know that every time one of the movie clips are added to the stage using addChild(), the stage shifts to the right by one pixel. I know that sounds odd, but it's literally true... the 0 line on the y axis is shifted to the right one pixel every time the movie clip is added. I have no idea how this could be happening. Here's the code that is doing the work: private function setupSlides():void { for(x = 0; x < TOTAL_SLIDES; x++) { var ClassReference:Class = getDefinitionByName("Slide" + (x+1)) as Class; var s:MovieClip = new ClassReference() as MovieClip; s.x = 9999; s.y = 9999; addChild(s); slides[x] = s; } } Any thoughts?

• Versioning code in two separate projects concurently with subverison

  - by Matt1776

  I have a need to create a library of Object Oriented PHP code that will see much reuse and aspires to be highly flexible and modular. Because of its independent nature I would like it to exist as its own SVN project. I would like to be able to create a new web project, save it in SVN as its own separate project, and include within it the library project code as well. During this process, while coding the web application code and making commits, I may need to add a class to the library. I would like to be able to do so and commit those changes back to the libraries project code. In light of all this I could manage the code in two ways Commit the changes to the library back to a branch of its original base project code and make the branch name relevant to the web project I was using it with Commit the changes to the library back to the original code, growing it in size regardless of any specific references that might exist. I have two questions How can I include this library project code into a new project yet not break the subversion functionality, i.e. allowing me to make changes to each project individually? How I can keep the code synchronized? If I choose the first method of managing the library code I may want to grab changes from another branch and pull it in for use in another.

• Suggestions for a django db structure

  - by rh0dium

  Hi Say I have the unknown number of questions. For example: Is the sky blue [y/n] What date were your born on [date] What is pi [3.14] What is a large integ [100] Now each of these questions poses a different but very type specific answer (boolean, date, float, int). Natively django can happily deal with these in a model. class SkyModel(models.Model): question = models.CharField("Is the sky blue") answer = models.BooleanField(default=False) class BirthModel(models.Model): question = models.CharField("What date were your born on") answer = models.DateTimeField(default=today) class PiModel(models.Model) question = models.CharField("What is pi") answer = models.FloatField() But this has the obvious problem in that each question has a specific model - so if we need to add a question later I have to change the database. Yuck. So now I want to get fancy - How do a set up a model where by the answer type conversion happens automagically? ANSWER_TYPES = ( ('boolean', 'boolean'), ('date', 'date'), ('float', 'float'), ('int', 'int'), ('char', 'char'), ) class Questions(models.model): question = models.CharField(() answer = models.CharField() answer_type = models.CharField(choices = ANSWER_TYPES) default = models.CharField() So in theory this would do the following: When I build up my views I look at the type of answer and ensure that I only put in that value. But when I want to pull that answer back out it will return the data in the format specified by the answer_type. Example 3.14 comes back out as a float not as a str. How can I perform this sort of automagic transformation? Or can someone suggest a better way to do this? Thanks much!!

• PHP - Drilling down Data and Looping with Loops

  - by stogdilla

  I'm currently having difficulty finding a way of making my loops work. I have a table of data with 15 minute values. I need the data to pull up in a few different increments $filters=Array('Yrs','Qtr','Day','60','30','15'); I think I have a way of finding out what I need to be able to drill down to but the issue I'm having is after the first loop to cycle through all the Outter most values (ex: the user says they want to display by Hours, each hour should be able to have a "+" that will then add a new div to display the half hour data, then each half hour data have a "+" to display the 15 minute data upon request. Now I can just program the number of outputs for each value (6 different outputs) just in-case... but isn't there a way I can make it do the drill down for each one in a loop? so I only have to code one output once and have it just check if there are any more intervals after it and check for those? I'm sure I'm just overlooking some very simple way of doing this but my brain isn't being clever today. Sorry in advance if this is a simple solution. I guess the best way I could think of it as a reply on a form. How you would check to see if it's a reply of a reply, and then if that reply has any replys...etc for output. Can anyone help or at least point me in the right direction? Or am I stuck coding each possible check? Thanks in advance!

• What files does JDIC need to run?

  - by Domchi

  I'm trying to call JDIC from my application, but I can't get it to run. What files do I need and where? From what I've been able to gather from their site, I basically need to put jdic.jar in classpath... however there is also a lib folder with jdic.jar with a bit different size, and jdic_native_applet.jar, jdic_stub_unix.jar, jdic_stub_windows.jar and several folders with what I gather are platform specific files. I get this exception when instantiating AssociationService: java.lang.ClassNotFoundException: org.jdesktop.jdic.filetypes.internal.AppAssociationReaderFactory_windows at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.jdesktop.jdic.filetypes.AssociationService.<init>(Unknown Source) at QuickTest.main(QuickTest.java:101) I've tried last "official" release and last alpha release. I'm running Java 6 and Win7 64bit. Does JDIC even work under Win7 (or 64bit, although I use 32bit Java)? I see no release after 2006, and no activity in the project after about 2008... while Win7 came in 2009. I know that parts of JDIC, like Desktop, were included in Java 6, however that doesn't seem to be the case with file associations. And if it doesn't, are there any (hopefully cross-platform) alternatives for managing file associations? There are some things for Windows only that I tried, but that requires running native commands with administrator privileges which I don't know how to pull, apart from asking user to run my app as administrator and then use Runtime.exec()... If there are no alternatives to JDIC, I'm interested if anyone has managed to handle file associations well with cross-platform installers?

• Missing tables on Scaffold Dynamic Data page

  - by Ben Amada

  I created a Linq-to-SQL DBML for the first time. I dragged and dropped all my tables over to the designer. The tables all appear in the designer.cs file. In Global.asax, I also have model.RegisterContext() with the ScaffoldAllTables = true option. The routes are also setup. I can pull up the Scaffolding page, but there's at least one table that is missing that I'm trying to get to show up. This missing table has a relationship with a child table that references it. The child table appears. When viewing data for the child table, the column that references the missing/parent table shows the numeric PK int value, rather than showing the "name". So instead of showing "Cars" it shows 1, and instead of showing "Planes" it shows 2, etc. There's another table in the DB that has the same type of structure as the missing table, and it is correctly appearing in the scaffolded tables. For this missing table, I've tried explicitly adding the ScaffoldTable attribute to no avail. Does anyone know what would cause a table like this to not appear in the list Scaffolded tables? Thanks very much.

• How can I abstract out the core functionality of several Rails applications?

  - by hornairs

  I'd like to develop a number of non-trivial Rails applications which all implement a core set of functionality but each have certain particular customizations, extensions, and aesthetic differences. How can I pull the core functionality (models, controllers, helpers, support classes, tests) common to all these systems out in such a way that updating the core will benefit every application based upon it? I've seen Rails Engines but they seem to be too detached, almost too abstracted to be built upon. I can seem them being useful for adding one component to an existing app, for example bolting on a blog engine to your existing e-commerce site. Since engines seem to be mostly self contained, it seems difficult and inconvenient to override their functionality and views while keeping DRY. I've also considered abstracting the code into a gem, but this seems a little odd. Do I make the gem depend on the Rails gems, and the define models & controllers inside it, and then subclass them in my various applications? Or do I define many modules inside the gem that I include in the different spots inside my various applications? How do I test the gem and then test the set of customizations and overridden functionality on top of it? I'm also concerned with how I'll develop the gem and the Rails apps in tandem, can I vendor a git repository of the gem into the app and push from that so I don't have to build a new gem every iteration? Also, are there private gem hosts/can I set my own gem source up? Also, any general suggestions for this kind of undertaking? Abstraction paradigms to adhere to? Required reading? Comments from the wise who have done this before? Thanks!

• What is Wordpress doing for content encoding in it's mysql database?

  - by qbxk

  For some convoluted reasons best left behind us, I require direct access the contents of a wordpress database. I'm using mysql 5.0.70-r1 on gentoo with wordpress 2.6, and perl 5.8.8 ftr. So, sometimes we get high-order characters in the blog, we have quite a few authors contributing too, for the most part these characters end up in wp's database in wp_posts.post_content or wp_postmeta.meta_value, Wordpress is displaying these correctly on it's site, but the database stores it using single byte encoding that I can't figure out how to convert to the correct string. Today's example: the blog shows this, and doesn't even seem to escape any chars in the html, Hãhãhães but the database, when viewed via the mysql prompt, has, Hãhãhães So clearly this is some kind of double-byte encoding issue, but I don't know how I can correct it. I need to be able to pull that second string from the database (b/c that's what it gives me) and convert it to the first one, and i need to do so using perl. also, just to help unmuddy any waters, I took these strings and printed out the ascii codes for each character using perl's ord() function. Here is the output of the "wrong" string H = 72 à = 195 £ = 163 h = 104 à = 195 £ = 163 h = 104 à = 195 £ = 163 e = 101 s = 115 This is the correct string, that I need to produce in my script H = 72 ã = 227 h = 104 ã = 227 h = 104 ã = 227 e = 101 s = 115

• #include - brackets vs quotes in XCode?

  - by Chris Becke

  In MSVC++ #include files are searched for differently depending on whether the file is enclosed in "" or <. The quoted form searches first in the local folder, then in /I specified locations, The angle bracket form avoids the local folder. This means, in MSVC++, its possible to have header files with the same name as runtime and SDK headers. So, for example, I need to wrap up the windows sdk windows.h file to undefine some macro's that cause trouble. With MSVS I can just add a (optional) windows.h file to my project as long as I include it using the quoted form :- // some .cpp file #include "windows.h" // will include my local windows.h file And in my windows.h, I can pull in the real one using the angle bracket form: // my windows.h #include <windows.h> // will load the real one #undef ConflictingSymbol Trying this trick with GCC in XCode didn't work. angle bracket #includes in system header files in fact are finding my header files with similar names in my local folder structure. The MSVC system means its quite safe to have a "String.h" header file in my own folder structre. On XCode this seems to be a major no no. Is there some way to control this search path behaviour in XCode to be more like MSVC's? Or do I just have to avoid naming any of my headers anything that might possibly conflict with a system header. Writing cross platform code and using lots of frameworks means the possibility of incidental conflicts seems large.

  It didn't seem like there was a post about this, so here goes. I've been working on a simple app to grab my time table from my school, and get it on my phone. Currently I'm working on the port on android but I've hit an issue. I get the error: java.io.IOException: -1 error loading URL urladress.

• Can I make an identity field span multiple tables in SQL Server?

  - by johnnycakes

  Can I have an "identity" (unique, non-repeating) column span multiple tables? For example, let's say I have two tables: Books and Authors. Authors AuthorID AuthorName Books BookID BookTitle The BookID column and the AuthorID column are identity columns. I want the identity part to span both columns. So, if there is an AuthorID with a value of 123, then there cannot be a BookID with a value of 123. And vice versa. I hope that makes sense. Is this possible? Thanks. Why do I want to do this? I am writing an APS.NET MVC app. I am creating a comment section. Authors can have comments. Books can have comments. I want to be able to pass an entity ID (a book ID or an author ID) to an action and have the action pull up all the corresponding comments. The action won't care if it's a book or an author or whatever. Sound reasonable?

• C++ compilers and back/front ends

  - by aaa

  Hello. for my own education I am curious what compilers use which C++ front-end and backend. Can you enlighten me where the following technologies are used and what hallmarks/advantages they have if any? Open64 - is it backend, front-end, or both? Which compilers use it? I encounter it in cuda compiler. EDG - as far as I can tell this is a backend use by Intel compilers and Comeau. do other compilers use it? I found quite a few references to it in boost source code. ANTLR - this is general parser. Do any common compilers use it? Regarding compilers: with front-end/backend does gcc compiler suite uses? does it have common heritage with any other compiler? what front-end/backend PGI and PathScale compilers use? what front-end/backend XL compiler uses (IBM offering). Thanks.

• codeigniter mulitple LIKE db query using associative array- but all from the same column name...?

  - by Inigo

  Hi, I'm trying to query my database using codeigniter's active record class. I have a number of blog posts stored in a table. The query is for a search function, which will pull out all the posts that have certain categories assigned to them. So the 'category' column of the table will have a list of all the categories for that post in no particular order, separated by commas, like so: Politics,History,Sociology.. etc. If a user selects, say, Politics and History, The titles of all the posts that have BOTH these categories should be returned. Right? So, the list of categories queried will be the array $cats. I thought this would work- foreach ($cats as $cat){ $this->db->like('categories',$cat); } By Producing this- $this-db-like('categories','Politics'); $this-db-like('categories','History'); (Which would produce- 'WHERE categories LIKE '%Politics%' AND categories LIKE '%History%') But it doesn't work, it seems to only produce the first statement. The problem I guess is that the column name is the same for each of the chained queries. There doesn't seem to be anything in the CI user guide about this (http://codeigniter.com/user_guide/database/active_record.html) as they seem to assume that each chained statement is going to be for a different column name. Does anyone know how I could do this? Thanks! edit- Of course it is not possible to use an associative array in one statement as it would have to contain duplicate keys- in this case every key would have to be 'categories'...

• MySQL to SQL Server ODBC Connector?

  - by Scott C.

  My boss wants to have data in MySQL DBs used for our website to be "linked and synced" with a Financial Server that has its DB in SQL Server. Sooooo...even though I have no idea how to accomplish this, this just sounds like an absolute nightmare especially since the MySQL DB is most likely going to be hosted in the cloud and not on a machine next to the Financial Server. Any ideas how to accomplish this? (within reason?) Also, his big thing is he wants to basically pull up the data from any record a user enters and using data pulled from that do all sorts of calculations using ANOTHER program that stores its data (apparently) in SQL Server. Thinking of all the data I might have to convert makes me very uneasy. Please tell a ODBC eliminates complicated junk like this. :/ I'm trying to talk him into just having MySQL do a nightly dump into a CSV file or something and using that (rather than connector) to update the SQL Server DBs. I guess I'm just not that comfortable with a server and/or programming I have no say over being connected DIRECTLY to my MySQL DB for the website. If there's no good answer for this, can anyone offer a suggestion as to what I can say to talk him out of this? (I'm a low-level IT guy w/ a decent grasp on programming...but I'm no expert - should I try to push this off to a seasoned IT pro?) Thanks in advance.

• Programmatically parse and edit C++ Source Files

  - by Kryten

  Hi, I want to able programmatically parse and edit C++ source files. I need to be able to change/add code in certain sections of code (i.e. in functions, class blocks, etc). I would also (preferably) be able to get comments as well. Part of what I want to do can be explained by the following piece of code: CPlusPlusSourceParser cp = new CPlusPlusSourceParser(“x.cpp”); // Create C++ Source Parser Object CPlusPlusSourceFunction[] funcs = cp.getFunctions(); // Get all the functions for (int i = 0; i &lt funcs.length; i++) { // Loop through all functions funcs[i].append(/* … code I want to append …*/); // Append some code to function } cp.save(); // Save new source cp.close(); // Close file How can I do that? I’d like to be able to do this preferably in Java, C++, Perl, Python or C#. However, I am open to other language API’s.

• Best Practice: Protecting Personally Identifiable Data in a ASP.NET / SQL Server 2008 Environment

  - by William

  Thanks to a SQL injection vulnerability found last week, some of my recommendations are being investigated at work. We recently re-did an application which stores personally identifiable information whose disclosure could lead to identity theft. While we read some of the data on a regular basis, the restricted data we only need a couple of times a year and then only two employees need it. I've read up on SQL Server 2008's encryption function, but I'm not convinced that's the route I want to go. My problem ultimately boils down to the fact that we're either using symmetric keys or assymetric keys encrypted by a symmetric key. Thus it seems like a SQL injection attack could lead to a data leak. I realize permissions should prevent that, permissions should also prevent the leaking in the first place. It seems to me the better method would be to asymmetrically encrypt the data in the web application. Then store the private key offline and have a fat client that they can run the few times a year they need to access the restricted data so the data could be decrypted on the client. This way, if the server get compromised, we don't leak old data although depending on what they do we may leak future data. I think the big disadvantage is this would require re-writing the web application and creating a new fat application (to pull the restricted data). Due to the recent problem, I can probably get the time allocated, so now would be the proper time to make the recommendation. Do you have a better suggestion? Which method would you recommend? More importantly why?

• Transfering a set with a Wildcarded Generic to a List in Java

  - by Daniel Bingham

  I have a data type that contains a set and a method that expects List<? extends MyClass>. The data type has Set<? extends MyClass>. I need to be able to move the stuff out of the set and into the List. The order it goes into the list doesn't matter, it just needs to start keeping track of it so that it can be reordered when displayed. Suffice to say that changing the Set into a List in the data type is out of the question here. This seems pretty easy at first. Create a new method that takes a Set instead of a List, changes it into a list and then passes it on to the old method that just took a list. The problem comes in changing the set to a list. public void setData(Set<? extends MyClass> data) { List<? extends Myclass> newData = ArrayList< /* What goes here? */ >(); for(ConcordaEntityBean o : data) { newData.add(o); } setData(newData); } Obviously, I can't instantiate an ArrayList with a wildcard, it chokes. I don't know the type at that point. Is there some way to pull the type out of data and pass it to ArrayList? Can I just instantiate it with MyClass? Is there some other way to do this?

• User will input some filter criteria -- how can I turn it into a regular expression for String.match

  - by envinyater

  I have a program where the user will enter a string such as PropertyA = "abc_*" and I need to have the asterisk match any character. In my code, I'm grabbing the property value and replacing PropertyA with the actual value. For instance, it could be abc_123. I also pull out the equality symbol into a variable. It should be able to cover this type of criteria PropertyB = 'cba' PropertyC != '*-this' valueFromHeader is the lefthand side and value is the righthand side. if (equality.equals("=")) { result = valueFromHeader.matches(value); } else if (equality.equals("!=")) { result = !valueFromHeader.matches(value); } EDIT: The existing code had this type of replacement for regular expressions final String ESC = "\\$1"; final String NON_ALPHA = "([^A-Za-z0-9@])"; final String WILD = "*"; final String WILD_RE_TEMP = "@"; final String WILD_RE = ".*"; value = value.replace(WILD, WILD_RE_TEMP); value = value.replaceAll(NON_ALPHA,ESC); value = value.replace(WILD_RE_TEMP, WILD_RE); It doesn't like the underscore here... abcSite_123 != abcSite_123 (evaluates to true) abcSite_123$1.matches("abcSite$1123") It doesn't like the underscore...

• Parsing: How to make error recovery in grammars like " a* b*"?

  - by Lavir the Whiolet

  Let we have a grammar like this: Program ::= a* b* where "*" is considered to be greedy. I usually implement "*" operator naively: Try to apply the expression under "*" to input one more time. If it has been applied successfully then we are still under current "*"-expression; try to apply the expression under "*" one more time. Otherwise we have reached next grammar expression; put characters parsed by expression under "*" back into input and proceed with next expression. But if there are errors in input in any of "a*" or "b*" part such a parser will "think" that in position of error both "a*" and "b*" have finished ("let's try "a"... Fail! OK, it looks like we have to proceed to "b*". Let's try "b"... Fail! OK, it looks like the string should have been finished...). For example, for string "daaaabbbbbbc" it will "say": "The string must end at position 1, delete superflous characters: daaaabbbbbbc". In short, greedy "*" operator becomes lazy if there are errors in input. How to make "*" operator to recover from errors nicely?

This code works fine in FF but Safari, for some reason, doesn't submit the form. I re-wrote the code using jquery to see if jquery's .submit() implementation handled the browser quirks better. Same result, works in FF doesn't work in safari. The following snippets are from the same page, which has some django template language mixed in. Here's the vanilla js attempt: function formSubmit(lang) { if (lang != '{{ LANGUAGE_CODE }}') { document.getElementById("setlang_form").submit(); } } Here's the jquery attempt: $(document).ready(function() { $('#lang_submit').hide() $('#setlang_form option').mouseup(function () { if ($(this).attr('value') != '{{ LANGUAGE_CODE }}') { $('#setlang_form').submit() } }); }); and here's the form: <form id="setlang_form" method="post" action="{% url django.views.i18n.set_language %}"> <fieldset> <select name="language"> {% for lang in interface_languages %} <option value="{{ lang.code }}" onmouseup="formSubmit('{{ lang.name }}')" {% ifequal lang.code LANGUAGE_CODE %}selected="selected"{% endifequal %}>{{ lang.name }}</option> {% endfor %} </select> </fieldset> </form> My question is, how can I get this working in Safari?

• Pattern for version-specific implementations of a Java class

  - by Mike Monkiewicz

  So here's my conundrum. I am programming a tool that needs to work on old versions of our application. I have the code to the application, but can not alter any of the classes. To pull information out of our database, I have a DTO of sorts that is populated by Hibernate. It consumes a data object for version 1.0 of our app, cleverly named DataObject. Below is the DTO class. public class MyDTO { private MyWrapperClass wrapper; public MyDTO(DataObject data) { wrapper = new MyWrapperClass(data); } } The DTO is instantiated through a Hibernate query as follows: select new com.foo.bar.MyDTO(t1.data) from mytable t1 Now, a little logic is needed on top of the data object, so I made a wrapper class for it. Note the DTO stores an instance of the wrapper class, not the original data object. public class MyWrapperClass { private DataObject data; public MyWrapperClass(DataObject data) { this.data = data; } public String doSomethingImportant() { ... version-specific logic ... } } This works well until I need to work on version 2.0 of our application. Now DataObject in the two versions are very similar, but not the same. This resulted in different sub classes of MyWrapperClass, which implement their own version-specific doSomethingImportant(). Still doing okay. But how does myDTO instantiate the appropriate version-specific MyWrapperClass? Hibernate is in turn instantiating MyDTO, so it's not like I can @Autowire a dependency in Spring. I would love to reuse MyDTO (and my dozens of other DTOs) for both versions of the tool, without having to duplicate the class. Don't repeat yourself, and all that. I'm sure there's a very simple pattern I'm missing that would help this. Any suggestions?

• Mercurial Subrepos, how to control which changeset I want to use for a subrepo?

  - by Lasse V. Karlsen

  I am reading up on subrepos, and have been running some tests locally, seems to work OK so far, but I have one question. How do I specify/control which changeset I want to use for a particular subrepo? For instance, let's say I have the following two projects: class library application o fourth commit o second commit, added a feature | | o third commit o initial commit | | o second commit |/ o initial commit Now, I want the class library as a subrepo of my application, but due to the immaturity of the longest branch (the one ending up as fourth commit), I want to temporarily use the "second commit" tip. How do I go about configuring that, assuming it is even possible? Here's a batch file that sets up the above two repos + adds the library as a subrepo. If you run the batch file, it will output: [C:\Temp] :test ... v4 As you can see from that last line there, it verifies the contents of the file in the class library, which is "v4" from the fourth commit. I'd like it to be "v2", and persist as "v2" until I'm ready to pull down a newer version from the class library repository. Can anyone tell me if it is possible to do what I want, and if so, what I need to do in order to lock my subrepo to the right changeset? Batch-file: @echo off if exist app rd /s /q app if exist lib rd /s /q lib if exist app-clone rd /s /q app-clone rem == app == hg init app cd app echo program>main.txt hg add main.txt hg commit -m "initial commit" echo program+feature1>main.txt hg commit -m "second commit, added a feature" cd .. rem == lib == hg init lib cd lib echo v1>lib.txt hg add lib.txt hg commit -m "initial commit" echo v2>lib.txt hg commit -m "second commit" hg update 0 echo v3>lib.txt hg commit -m "third commit" echo v4>lib.txt hg commit -m "fourth commit" cd .. rem == subrepos == cd app hg clone ..\lib lib echo lib = ..\lib >.hgsub hg add .hgsub hg commit -m "added subrepo" cd .. rem == clone == hg clone app app-clone type app-clone\lib\lib.txt
