• how to iterate over non-English file names in PHP

  - by Sabya

  I have a directory which contains several files, many of which has non-english name. I am using PHP in Windows 7. I want to list the filename and their content using PHP. Currently I am using DirectoryIterator and file_get_contents. This works for English files names but not for non-English (chinese) file names. For example, I have filenames like "?? ?? ?????????.eml", "hello ??????.eml". DirectoryIterator is not able to get the filename using ->getFilename() file_get_contents is also not able to open even if I hard code the filename in its parameter. How can I do it?

• [C++]Advantage of using a static member function instead of an equivalent non-static member function

  - by jonathanasdf

  I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

• Do i need to insert one fake row in database ?

  - by Ankit Rathod

  Hello, I have few tables like example. Users Books UsersBookPurchase UID BookId UserId UName Name BookId Password Price Email This is fine. I am having my own login system but i am also using some 3rd party to validate like OpenID or facebook Authetication. My question is if the user is able to log in successfully using OpenID or facebook Authentication, what steps do i need to do i.e do i have to insert one fake row in Users table because if i do not insert how will integrity be maintained. I mean what user id should i insert in UsersBookPurchase when the person who has logged in using Facebook Authentication has made a purchase because the UserId is reference key from Users table. Please give me a high level overview of what i need to do because this is fairly common scenario. Thanks in advance :)

• ADO.NET Multiple simultaneous reads from an open database.

  - by Deverill

  Answer not needed - my logic was wrong and this question is invalid. Charles helped me see where I went off-tracks. Thanks I have a utility that moves data from one source to another. In the process of writing the record I check to see if it exists and do an update/insert as necessary. The difficulty I have is that as I'm writing the main record info there is a 2nd table for "custom data" that I have to check to see if it exists and do an update/insert for that as well. Example: I may be loading a pencil sharpener that may or may not exist. While I'm writing it into destination it has characteristics such as style, color, etc. and each of them may or may not exist. As written I seem to need to have 2 DataReaders open, one for the sharpener and one to check for and update color. I am new to ADO.NET, but not to programming and it's more complicated than I listed but for sanity's sake I didn't put all the details. My question is: What am I missing? You can't have 2 readers open at the same time on a connection, yet I can't close the first if I'm stepping through all products. It seems inefficient to have 2 connections, readers, etc. for this. Is there a feature of ADO.NET DBs that I'm missing? How would you do it? Thanks!

• Non laggy movement in Flex or WPF

  - by PaN1C_Showt1Me

  I'm trying to learn something about 2D games programming. For this purpose I've downloaded many samples developed in: Flex and Microsoft WPF. I've noticed that all the animations / moving objects are kind of non-smooth. I've seen a Flex example with double buffering which solved the image flickering, but it was laggy too. WPF example too. Just to mentioned, all examples were drawing on Canvas. I'm just curious, is it possible to have a wonderful non-laggy movement on the GUI in Flash or WPF ? (e.g. like a real game, coded in C++)

• Upload database backup from mysql to Amazon S3 or Glacier without creating local file

  - by Rubem Azenha

  Is there a tool that makes possible to backup a Mysql database to Amazon S3 or Amazon Glacier without having o create a local file with the database contents? Something like that: mysqldump -u root -ppass -h host --all-databases | magical-s3-tool s3-bucket backup-yyyy-mm-dd.sql This magical tool would use the pipe data and transfer the backup data directly to S3, without creating a local file.

• Changing MSSQL Database sorting

  - by plaisthos

  I have a request to change the collation of a MS SQL Database: ALTER DATABASE solarwind95 collate SQL_Latin1_General_CP1_CI_AS but I get this strange error: Meldung 5075, Ebene 16, Status 1, Zeile 1 Das 'Spalte'-Objekt 'CustomPollerAssignment.PollerID' ist von 'Datenbanksortierung' abhängig. Die Datenbanksortierung kann nicht geändert werden, wenn ein schemagebundenes Objekt von ihr abhängig ist. Entfernen Sie die Anhängigkeiten der Datenbanksortierung, und wiederholen Sie den Vorgang. Sorry for the german errror message. I do not know how to switch the language to english, but here is a translation: Translation: Message 5075, Layer 16, Status 1, Row 1 The 'column' object 'CustomPollerAssignment.PollerID' depends on 'Database sorting. The database sorting cannot be changed if a schema bound object depends on it. Remove the dependency of the database sortieren and retry. I got a ton more of the errors like that.

• Non-graphical linearity estimation

  - by aL3xa

  In my previous post, I was looking for correlation ratio (η or η2) routines in R. I was surprised by the fact that no one uses η for linearity checking in the GLM procedures. Let's start form a simple example: how do you check linearity of bivariate correlation? Solely with scatterplot? There are several ways of doing this, one way is to compare linear and non-linear model R2, then to apply F test to seek for significant difference between them. Finally, the question is: How do you check linearity, the "non-grafical" way?

• Database Design: A proper table design for large number of column values.

  - by Jake

  I wish to perform an experiment many different times. After every trial, I am left with a "large" set of output statistics -- let's say, 1000. I would like to store the outputs of my experiments in a table, but what's the best way...? Option 1 Have a table with 1000 columns. Seems like a bad idea. What if the number of statistics one day exceeds the maximum number of columns? Option 2 Have a table with three columns. Let's say, ID, StatisticType, and StatisticValue. That way, you can have as many statistics as you want. However, reading a single experiments statistics becomes more complicated. Moreover, what if different statistics are different data types?? Any suggestions?

• C# ASP.NET update SQL database with values from text boxes

  - by Sir Graystar

  Here's what I have. User enters values into text boxes (personal information etc.) and then presses a save changes button. The values in these text boxes get stored in an SQL database. The problem I have is that when updating the database using the values from the text boxes, the page refreshes and the values in the text boxes are lost (or rather they return to the values that are already in the database as the data from the database is loaded into the text boxes on Page_Load). When I update the database using valuse stored in variables it all works fine. What is the best way to update with the values from the text boxes?

• Dump Microsoft SQL Server database to an SQL script

  - by Matt Sheppard

  Is there any way to export a Microsoft SQL Server database to an sql script? I'm looking for something which behaves similarly to mysqldump, taking a database name, and producing a single script which will recreate all the tables, stored procedures, reinsert all the data etc. I've seen http://vyaskn.tripod.com/code.htm#inserts, but I ideally want something to recreate everything (not just the data) which works in a single step to produce the final script.

• A Simulator for a non-deterministic Push-Down Automaton

  - by shake

  Well, i need to make simulator for non-deterministic Push-Down Automaton. Everything is okey, i know i need to do recursion or something similar. But i do not know how to make that function which would simulate automaton. I got everything else under control, automaton generator, stack ... I am doing it in java, so this is maybe only issue that man can bump on, and i did it. So if anyone have done something similar, i could use advices. This is my current organisation of code: C lasses: class transit: list -contains non deterministic transitions state input sign stack sign class generator it generate automaton from file clas NPA public boolean start() - this function i am having trouble with Of course problem of separate stacks, and input for every branch. I tried to solve it with collection of objects NPA and try to start every object, but it doesn work :((..

• how to use .mdf while developing

  - by Masna

  I use a .mdf database for my asp.net Mvc project. The project is on source control on a tfs. When I debug the project, Visual Studio copies the database in to the debugmap. The problem is, when I debug next time, the changes (while testing the previous time) in the database are gone. The reason of this I know, Visual studio copies the original database again in to the debug map. Can I change some settings in Visual studio to work always on the same database without copying the database after each debug session myself? So I can keep my modified records? Or how do I have to work with my database while developing? Greets

• XSD generation from a MS SQL database using schemas

  - by madprog

  I'm willing to use NDbUnit on a MS SQL database which uses schemas. I have to generate the XSD schema from the database. Visual Studio has a tool to do that, but Visual Studio 2005 doesn't include the schema information in the generated XSD. Therefore, NDbUnit fails because the generated SQL queries do not match the database. Worse, when I try to use Proteus, the XSD schema doesn't validate against the database, and Proteus fails with a warning telling that data could be lost if this check was skipped. So, my question is: is there any tool that would generate my XSD schema properly and from the database information?

• Code First / Database First / Model First : are they just personnal preferences?

  - by Antoine M

  Merely knowing the internal functionality of each approaches, and after reading a lot of posts, I still can't figure out if each one of them is just a matter of personnal preference for the developper or if they deserve different axes of productivity ? Does one of them should be applyed for some specific productivity needs or MS is just beeing kind offering three different flavours ? Should we consider CF as a sort of improvement over DBF or MF and thinking of it as a futur standard on wich spending a peculiar intelectual investment ... ? Is there a link showing a sort of synthetic table with un-passionate pros and cons for each approach, a little bit like for web-forms and MVC. Sorry for those who will find this question redondant. I know it is.

• MySQL database Int overflow and can't login in.

  - by Ryan SMith

  I have a MySQL database on my server and I"m pretty sure it's an int over flow on one table with an auto_increment field that's crashing it. I can delete the table, it's not very important, but I can't get into the server. Is there anyway to delete that database from the file system or without logging into MySQL? HELP! THE WORLD IS ENDING!

• Sqlite. How to create an index in attached DB?

  - by kappa

  I have a problem with adding index to memory database attached to main database. 1) I open the database (F) from file 2) Attach the :memory: (M) database 3) Create tables in database M 4) Copy data from F to M I would also like to create an index in database M, but don't know how to do that. This code creates index but in F database: sQuery = "CREATE INDEX IF NOT EXISTS [INDID] ON [PANEL]([ID] ASC);"; I tried to add the name qualifier before table name like this: sQuery = "CREATE INDEX IF NOT EXISTS [INDID] ON [M.PANEL]([ID] ASC);"; but SQLite returns with message that column main.M.PANEL does not exist. What can I do?

• Using a set of numbers inside a database without creating a temporary table

  - by Zizzencs

  I have a set of numbers and a table in a database with the id (primary key) and text (not null) columns. I would like to create a query that returns all the numbers in the set and the associated text from the table. Unfortunately not all numbers exist in the database's id column, so this won't work: select id, text from table where id in (<set of numbers>) For the non-existing ids the best would be to return null as the text from the query. Is there a way to produce the desired output without first creating a temporary table from the set inside the database? The database engine in use is a Microsoft SQL Server 2008 SP1 but I'd be interested in any solution with any database engine.

• "FirstName" and "LastName" store in database USER or USER_PROFILE table?

  - by Khou

  Currently I store the user's "FirstName" and "LastName" in the USER table, but i also have a USER PROFILE table (which provides additional information about the user) and it would makes sense to have the user's "FirstName" and "LastName" in the USER PROFILE table aswell. So what do i do? make two copies of "FirstName" and "LastName"?

• Strategy for developing namespaced and non-namespaced versions of same PHP code

  - by porneL

  I'm maintaining library written for PHP 5.2 and I'd like to create PHP 5.3-namespaced version of it. However, I'd also keep non-namespaced version up to date until PHP 5.3 becomes so old, that even Debian stable ships it ;) I've got rather clean code, about 80 classes following Project_Directory_Filename naming scheme (I'd change them to \Project\Directory\Filename of course) and only few functions and constants (also prefixed with project name). Question is: what's the best way to develop namespaced and non-namespaced versions in parallel? Should I just create fork in repository and keep merging changes between branches? Are there cases where backslash-sprinkled code becomes hard to merge? Should I write script that converts 5.2 version to 5.3 or vice-versa? Should I use PHP tokenizer? sed? C preprocessor? Is there a better way to use namespaces where available and keep backwards compatibility with older PHP?
