• Magento: Syncing product/category translations from "Store 1 > German Store View" to "Store 2 > German Store View"

  - by mattalexx

  For two different store Views using the same locale, it is easy to manage translations for miscellaneous text that's stored in CSV files. It's just a question of configuring the locale correctly so the correct CSV files will be used. But my client has entered a bunch of translations for products and categories into the admin by changing the scope to "Store 1 German" and setting the translations. But now he has Store 2, with a German store view. How does he keep "Store 1 German Store View" and "Store 2 German Store View" in sync?

• FileReference and HttpService Browse Image Modify it then Upload it

  - by user177787

  Hello, I am trying to do an image uploader, user can: - browse local file with button.browse - select one and save it as a FileReference. - then we do FileReference.load() then bind the data to our image control. - after we make a rotation on it and change the data of image. - and to finish we upload it to a server. To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image: private function TurnImage():void { //Turn it var m:Matrix = _img.transform.matrix; rotateImage(m); _img.transform.matrix = m; } Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();. Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.

• Marionette multi user/roles application

  - by Fabrizio Fortino

  I have to build a pretty complex application using Backbone Marionette. The user interface has to handle multiple users with different roles. For example the 'admin' user will see the complete menu whereas the 'guest' user will access a subset of the same menu. Moreover some views will be accessible to all the users but the functions inside them (add, edit, delete) need to be profiled on the different roles. I am not sure about the right approach to use in order to solve this issue. I could have different templates for the different roles but in this case plenty of code will be duplicated inside them. Is there any best practice (or maybe some example) to sort my problem out using Marionette? Thanks in advance, Fabrizio

• Compile a shared library statically

  - by Simon Walker

  I've got a shared library with some homemade functions, which I compile into my other programs, but I have to link the end program with all the libraries I have used to compile the static library. Here is an example: I have function foo in the library which requires a function from another library libbar.so. In my main program to use function foo I have to compile it with the -lbar flag. Is there a way I can compile my library statically so it includes all the required code from the other libraries, and I can compile my end program without needing the -lbar flag? Cheers

• Problem about python import with error

  - by xiao

  Hello, I have write a small python module with one class and two functions. The skeleton of the module is as following: #file name: test_module.py class TestClass: @classmethod def method1(cls, param1): #to do something pass def __init__(self, param1): #to do something ... def fun1(*params): #to do something ... def fun2(*params): #to do something ... Another py file is a small script which imports function and class from the module, as following: import sys from test_module import TestClass, fun1, fun2 def main(sys_argv): li = range(5) inst1 = TestClass(li) fun1(inst1) fun2(inst1) return if __name__ == "__main__": main(sys.argv) But when I execute the script, it is broken with following message: ./script.py: line 4: syntax error near unexpected token `(' ./script.py: line 4: `def main(sys_argv):' I am not sure what the problem is. Is it a problem with import? But when I try to import the module in ipython, everything is just ok.

• Type patterns and generic classes in Haskell

  - by finnsson

  I'm trying to understand type patterns and generic classes in Haskell but can't seem to get it. Could someone explain it in laymen's terms? In [1] I've read that "To apply functions generically to all data types, we view data types in a uniform manner: except for basic predefined types such as Float, IO, and ?, every Haskell data type can be viewed as a labeled sum of possibly labeled products." and then Unit, :*: and :+: are mentioned. Are all data types in Haskell automatically versions of the above mentioned and if so how do I figure out how a specific data type is represented in terms of :*:, etc? The users guide for generic classes (ch. 7.16) at haskell.org doesn't mention the predefined types but shouldn't they be handled in every function if the type patterns should be exhaustive?

• Data-separation in a Symfony Multi-tenant app using Doctrine

  - by Prasad

  I am trying to implement a multi-tenant application, that is - data of all clients in a single database - each shared table has a tenant_id field to separate data I wish to achieve data separation by adding where('tenant_id = ', $user->getTenantID()) {pseudoc-code} to all SELECT queries I could not find any solution up-front, but here are possible approaches I am considering. 1) crude approach: customizing all fetchAll and fetchOne functions in every class (I will go mad!) 2) using listeners: possibly coding for the preDqlSelect event and adding the 'where' to all queries 3) override buildQuery(): could not find an example of this for front-end 4) implement contentformfilter: again need a pointer Would appreciate if someone could validate these & comment on efficieny, suitability. Also, if anyone has achieved multitenancy using another strategy, pl share. Thanks

• How to manage end user documentation for a project under continuous integration?

  - by mcdon

  I have a project under continuous integration and would like to add end user documentation to the project. The end user documentation is a user manual, not API documentation. In our environment we use windows, c#, msbuild, cruisecontrol.net and subversion. We are currently using DocToHelp to create our help file, which is based on an msword document. I'm looking for some guidance on how to manage the end user documentation. What documentation tools should I use? Should any of the documentation tools be part of the build script? Should the output files from the documentation tool be stored in subversion? What type of help files would be best to use?

• Java variables -> replace? RAM optimization

  - by poeschlorn

  Hi guys, I just wanted to know what happens behind my program when I declare and initialize a variable and later initialize it again with other values, e.g. an ArrayList or something similar. What happens in my RAM, when I say e.g. this: ArrayList<String> al = new ArrayList<String>(); ...add values, work with it and so on.... al = new ArrayList<String>(); So is my first ArrayList held in RAM or will the second ArrayList be stored on the same position where the first one has been before? Or will it just change the reference of "al"? If it is not replaced...is there a way to manually free the RAM which was occupied by the first arraylist? (without waiting for the garbage collector) Would it help to set it first =null? Nice greetings, poeschlorn

• object representation and value representation

  - by FredOverflow

  3.9 §4 says: The object representation of an object of type T is the sequence of N unsigned char objects taken up by the object of type T, where N equals sizeof(T). The value representation of an object is the set of bits that hold the value of type T. For trivially copyable types, the value representation is a set of bits in the object representation that determines a value, which is one discrete element of an implementation-defined set of values. Does "The value representation of an object" imply that values are always stored in objects? What is the value representation of non-trivially copyable types?

• Is a .Net membership database portable, or are accounts somehow bound to the originating Web site or

  - by Deane

  I have an ASP.Net Web site using .Net Membership with a SQL Server provider, so the users and roles are stored in the SQL tables created by Aspnet_regsql.exe. Is this architecture totally self-contained and portable, or are users in it somehow bound to the specific Web site on which they create their account? Put another way, if we create a bunch of users in dev or UAT, the back up and restore this database to another server, accessed under another domain name, should it still work just fine? We're seeing some odd behavior when we move the database, like users losing group affiliation and such, and I'm curious how portable and environment-agnostic this database really is. I have a sneaking suspicion that something is bound to the machine key or the domain.

• What web UI framework is most suitable for building dynamic pages / forms?

  - by waxwing

  Hello, We are at a stage where we are considering different Web UI frameworks (most likely component based ones such as GWT, JSF, Wicket, Vaadin, etc). One of the main use cases / constraints is that it must support generating dynamic pages. I.e., the page/form layout and components is stored in a database and is changeable at runtime, and from this pages are generated. We are also going to write static layouts, but that is not the main focus of this question. I thought maybe the user community here can share experiences of different frameworks in this context. Are there differences in ease of implementation and what is suitable?

• ACCESS 2003 Excel 2003 : VBA for opening Excel file from Access and copying a pictre from excel the

  - by Justin

  So I have an excel workbook that has a nice global map of shaperange objects. With some very simple code I can change the colors, group and ungroup collections of countries into arrays, etc...and it works pretty well. However, I would like to bring this into Access. So I could copy and paste all the shapes into an access form manually, but then they become pictures and I cannot change the colors of the countries (shaperange objects) to have the map act interactively as I can in excel. So I am thinking that I know how to use excel functions from access, and how to open excel from access. Is there a way to copy an object from excel (I know the file name and the shape name that i mean to copy everytime), and bringing it back to access to paste on a form? Atypical, I know, all my Access questions are. Thanks!

• Sparx Enterprise Architect conversion (from source to UML)

  - by user228938

  I need to make a UML class diagram for a project. I used Sparx Enterprise Architect in the past to generate source code from a diagram so I'm using that. The project is complete so all of the code is done and I don't really want to write all the classes / functions manually, so I was trying to generate the diagram from the source code but can't seem to find a way to do it. I searched online and on their website but nothing. Any help appreciated. Thanks in advance.

• ORM framework that extends base class with database-implementation.

  - by aioobe

  I have a game consisting of a client / server + a webpage. A central notion in both client and game-/webserver is an Account. Accounts are stored in a database thus I'm in need of some ORM and recently had a look at Hibernate and Cayenne. My understanding however, is that both frameworks provide an "DatabaseBackedAccount"-class which I extend with my other Account methods. My problem is that the Account class is reused heavily on the client side, and I would obviously not want to include database-related code on the client implementation. My current solution is to have an Account class (shared by server and client) and extend this with a DatabaseBackedAccount (overriding setter-methods and providing a commit method) on the server side. I find this quite natural and nice, however I've had to implement all gory sql-details and ORM myself. Is there any way to "turn the table" in any existing ORM framework, so that the generated classes extend my existing class?

• FORTRAN function returning an array causes a segfault (calling from C++)

  - by Dane Larsen

  Basically, here's my problem. I'm calling someone else's FORTRAN functions from my C++ code, and it's giving me headaches. Some code: function c_error_message() character(len = 255) :: c_error_message errmsg(1:9) = 'ERROR MSG' return end That's the FORTRAN function. My first question is: Is there anything in there that would cause a segfault? If not, then second: What does that return? A pointer? I'm trying to call it with the following C statement: char *e = c_error_message_(); That causes a segfault. c_error_message(); That too causes a segfault. I declared c_error_message_() earlier on with the following code: extern"C" { char* c_error_message_(); } Would declaring a function with a different return type than the actual return type cause a segfault? I'm at a loss. Thanks for any replies.

• Simple XML parsing with Google Picasa API and JQuery

  - by zeedog

  I'm starting to look into Google's Picasa API for photo data, which provides you with a big XML file with info about albums and photos. I'm doing some quick and dirty tests to parse the XML file (which is saved locally to my hard drive for now) with JQuery and pull out the album id's, which are stored as "gphoto:id" tags, and display them in a div: $(document).ready(function() { $.get( 'albums.xml', function(data) { $(data).find('entry').each(function() { var albumId = $(this).children('gphoto:id').text(); $('#photos').append(albumId + '<br />'); }) }) }) I'm getting the following error in the console: jquery.js:3321 - Uncaught Syntax error, unrecognized expression: Syntax error, unrecognized expression: id This will work with other tags in the XML file (such as title, author, updated, etc.), but I'm trying to understand what's going on here. Does it have to do with the colon in "gphoto:id", somehow?

• Best .NET Framework compression class?

  - by Jack

  Hi all Yes, I know GZipStream or DeflateStream is the common ones in .NET Framework which handle compression/decompression. I wish to have compress/decompress functions in my program, but I wish a .NET Framework C# one, not a 3rd party open source. I can't use because of those copyright restrictions in my program. GZipStream and DeflateStream are not so good. for e.g., GZipStream compress a file to 480KB while 7Zip compress the same file to the size of 57KB. Does Microsoft have other good compression methods??? Thanks

• Interview question - c#

  - by ltech

  I was tasked to conduct my first interview and would like to pose my question to this world for both their feedback on my question and also on their solutions. Question: I have a legacy system with users and files, the info of all files pertaining to a user are stored on a flat file. I want to upgrade this system by storing all info on a db, design tables, and create a C# system that will populate the new db as well as ftp the files to a new path. Define the desgin consideration and develop a prototype. Note: We are looking more for what design one would use and why rather than code that compiles. If it does then kudos to you and we will give it more weight. @Tim C, I did show the interviewee the file: User1234.txt UserID=1234 ParentPath=\\somewhere\nowehere\everywhere\1234 FileCount=20 File0=something0.ext .. File19=something19.ext @Tim C, I have never conducted an interview and I followed a script given to me by my senior developer who was absent.

• Why is the 'if' statement considered evil?

  - by Vadim

  I just came from Simple Design and Testing Conference. In one of the session we were talking about evil keywords in programming languages. Corey Haines, who proposed the subject, was convinced that if statement is absolute evil. His alternative was to create functions with predicates. Can you please explain to me why if is evil. I understand that you can write very ugly code abusing if. But I don't believe that it's that bad.

• Remote (RDP) utility with mstscax.dll

  - by dboarman-FissureStudios

  I am looking for information on using mstscax.dll in VB. The goal is to create a utility that logs into a remote service in the same manner as remote desktop. However, my utility is not required to show the desktop. I have a series of commands that I will start off with that will look for users, reset logins, shadow, and message. I have been using a batch file on my RDP to perform these functions, but we are already looking for more functionality and power than what the batch commands can offer. I am googling 'mstscax.dll' but the results have been less than satisfactory although I continue to search. Does anyone have any good references? Is this even going to be possible?

• google maps v3 distance

  - by Shane

  Trying to create a new version of the map functions seen here: http://www.daftlogic.com/projects-google-maps-distance-calculator.htm but using the v3 api. So far I am able to set markers on click and can draw the geodesic polyline. The issues I am currently running into are: Updating the poly-line on marker drag I'm pretty sure I have to put each marker in an array and do a for loop so that I can keep clicking and adding points that will add to the total distance. Properly displaying distance. I have created a jsfiddle: http://jsfiddle.net/wyZyS/ EDIT: I realize I have nothing calling the "update" function. I am trying to create the array for each marker currently. The calculation you see is converting meters to nautical miles.

• What does xp_qv do in SQL Server?

  - by Chris

  Last night one of our SQL servers developed some major problems and after a colleague stopped, started, and all the usual things it started checking and rebuilding databases and is now running an extended stored procedure called "xp_qv". The internet seems to be very short of information on what this procedure does or anythign like that so I was hoping somebody here might be able to help. I should add that I assume it is meant to be running so the question isn't "Can I stop it" or anything like that, its just curiosity in what it is doing in the hope that it will help determine how long before things are usable again...

• Erlang bit indexing

  - by GTDev

  I am currently trying to learn erlang and what I am trying to do is to perform an operation on specific indices of an array stored in a bit array or int. If there is a 0 in a position, the index into the array at that position is not used. So envision the following: Example the array is: [1, 3, 5, 42, 23] My bit array is: 21 = 10101 in binary so I'm using indicies 1,3,5 so I'm calling a function on [1, 5, 23] my function is of the form my_function(Array, BitArray) -> SubArray = get_subarray_from_bitarray(Array, BitArray), process_subarray(SubArray). And I need help with the get_subarray_from_bitarray(). I know erlang has special syntax around bit strings (something like <<) so is there an efficient way of indexing into the bit array to get the indicies?
