  • PHP object access using string

    - by Rob Waring
    Hi all, I have an object in PHP with some very odd property names. I just need to know how to access a property when it's name is "//www.w3.org/1999/02/22-rdf-syntax-ns#type". I found something that suggested $object->{'//www.w3.org/1999/02/22-rdf-syntax-ns#type'}; but that doesn't seem to work. Thanks in advance Rob

  • Ninject with Object Initializers and LINQ

    - by Alexander Kahoun
    I'm new to Ninject so what I'm trying may not even be possible but I wanted to ask. I free-handed the below so there may be typos. Let's say I have an interface: public interface IPerson { string FirstName { get; set; } string LastName { get; set;} string GetFullName(); } And a concrete: public class Person : IPerson { public string FirstName { get; set; } public string LastName { get; set; } public string GetFullName() { return String.Concat(FirstName, " ", LastName); } } What I'm used to doing is something like this when I'm retrieving data from arrays or xml: public IEnumerable<IPerson> GetPeople(string xml) { XElement persons = XElement.Parse(xml); IEnumerable<IPerson> people = ( from person in persons.Descendants("person") select new Person { FirstName = person.Attribute("FName").Value, LastName = person.Attribute("LName").Value }).ToList(); return people; } I don't want to tightly couple the concrete to the interface in this manner. I haven't been able to find any information in regards to using Ninject with LINQ to Objects or with object initializers. I may be looking in the wrong places, but I've been searching for a day now with no luck at all. I was contemplating putting the kernel into an singleton instance and seeing if that would work, but I'm not sure that it will plus I've heard that passing your kernel around is a bad thing. I'm trying to implement this in a class library currently. If this is not possible, does anyone have any examples or suggestions as to what the best practice is in this case? Thanks in advance for the help. EDIT: Based on some of the answers I feel I should clarify. Yes, the example above appears short lived but it was simply an example of one piece that I was trying to do. Let's give a bigger picture. Say instead of XML I am gathering all my data through a 3rd party web service and I'm creating an interface for it, the data could be a defined object in the wsdl or it could sometimes be an xml string. IPerson could be used for both the Person object and a User object. I will be doing this inside of a separate class library, because it needs to be portable and will be used in other projects, and handing it to an MVC3 Web Application and the objects will be used in javascript as well. I appreciate all the input so far.

  • exclude private property from print_r or object?

    - by Hailwood
    Basically I am using Code Igniter, and the Code Igniter base class is huge, when I print_r some of my objects they have the base class embedded inside them. this makes it a pain to get the information I actually wanted (the rest of the properties). So, I am wondering if there is a way I can hide, or remove the base class object? I have tried clone $object; unset($object->ci); print_r($object); but of course the ci property is private. the actual function I am using for dumping is: /** * Outputs the given variables with formatting and location. Huge props * out to Phil Sturgeon for this one (http://philsturgeon.co.uk/blog/2010/09/power-dump-php-applications). * To use, pass in any number of variables as arguments. * Optional pass in "true" as final argument to kill script after dump * * @return void */ function dump() { list($callee) = debug_backtrace(); $arguments = func_get_args(); $total_arguments = count($arguments); if (end($arguments) === true) $total_arguments--; echo '<fieldset style="background: #fefefe !important; border:2px red solid; padding:5px">'; echo '<legend style="background:lightgrey; padding:5px;">' . $callee['file'] . ' @ line: ' . $callee['line'] . '</legend><pre>'; $i = 0; foreach ($arguments as $argument) { //if the last argument is true we don't want to display it. if ($i == ($total_arguments) && $argument === true) break; echo '<br/><strong>Debug #' . (++$i) . ' of ' . $total_arguments . '</strong>: '; if ((is_array($argument) || is_object($argument)) && count($argument)) { print_r($argument); } else { var_dump($argument); } } echo '</pre>' . PHP_EOL; echo '</fieldset>' . PHP_EOL; //if the very last argument is "true" then die if (end($arguments) === true) die('Killing Script'); }

    I have such an object : var options = {1: 'Running', 2: 'Falling', 3: 'Collapsing wall', 4: (...)}; I'd like to create form's select element with ooptions taken from this object, so something like that (code I tried which is not working, but you can get the idea) : html = '<form action="" ><select name="block-action"><option>-------</option>'; for(k in obj){ html += '<option value="'+k+'">'+obj[k]+'</option>' } html += '</select></form>'

  • When to use reflection to convert datarow to an object

    - by Daniel McNulty
    I'm in a situation now were I need to convert a datarow I've fetched from a query into a new instance of an object. I can do the obvious looping through columns and 'manually' assign these to properties of the object - or I can look into reflection such as this: http://www.codeproject.com/Articles/11914/Using-Reflection-to-convert-DataRows-to-objects-or What would I base the decision on? Just scalability??

  • javascript - query object graph?

    - by Scott
    Given an object like this: var obj = { first:{ second:{ third:'hi there' } } }; And a key like this "first.second.third" How can I get the value of the nested object "hi there"? I think maybe the Array.reduce function could help, but not sure.

  • Android SQLite database locale, locking, and version

    - by gdoten
    In some books and online I see these method calls being made after a database is created: db.setLocale(Locale.getDefault()); db.setLockingEnabled(true); db.setVersion(DB_VERSION); Why is this done? As far as I can tell, after creating a new database, the system adds a table named android_metadata with one field named locale and that table has one row with the locale field set to "en_US". Now I assume the column has that value because I am using a U.S. phone, and if I were using a phone from a different region then the locale field would be set appropriately. Can anyone confirm this? I'm guessing that the setLocale method would only be useful in the case that you install a pre-built database onto a phone and then want to change the locale to match the phone's locale. Sound right? The documentation for setLockingEnabled says it defaults to true so there's no need to make that call, right? Lastly, what's with the call to setVersion? I can't find a table that contains this information so I've been assuming that the database file itself stores the version number somewhere. So when I create a database, which requires you to have already specified the version number in the call to the SQLiteOpenHelper constructor, there's no point in calling setVersion. Again, perhaps this method exists for the case of installing a pre-built database to a device and you then wish to change the database's version (though I can't think of when doing this would make sense). Thanks for any insight!

  • using a database and deploying the application

    - by evan
    I have a WPF application that stores a large amount of information in XML files and as the user uses the application they add more information to the XML files. It's basically using the XML files as a database. Since over the life of the program the XML files have gotten quite large, and I've been think about putting the data on a website, I've been looking into how to move all the information into an SQL database. I've used SQL databases with web applications (PHP, Ruby, and ASP.NET) but never with a Desktop application. Ideally I'd like to be able to keep all the information in one database file and distribute it along with the application without requiring the user to connect to a remote database (so they don't need an internet connection - though eventually it would be nice if could compare the local file's version with one online somewhere and update if necessary) and without making them install a local database server on their computer. Is this possible? I'd also like to use LINQ with any new database solution so switching to a database doesn't force to many changes (I read the XML with LINQ). I'm sure this question has been asked and that there are already some good tutorials on the subject but I just can't find them.

  • Managing My Database in Source Control

    - by Jason
    As I am working with a new database project (within VS2008), and as I have never developed a database from scratch, I immediately began looking into how to manage a database within source control (in this case, Subversion). I found some information on SO, including this post: Keeping development databases in multiple environments in sync. One of the answers in particular pointed to a number of a links, all of which had good, useful information. I was reading a series of posts by K. Scott Allen which describe how he manages database change. From my reading (and please pardon the noobishness of my question), it seems as though the database itself is never checked into a repository. Rather, scripts that can build the database, along with test data (which is also populated from scripts) is checked into the repository. Ultimately, this means that, when a developer is testing his or her app, these scripts, which are part of the build process, are run. This ensures that the database is up-to-date, but is also run locally from every developer's machine. This makes sense to me (if I am indeed reading that correctly). However, if I am missing something, I would appreciate correction or additional guidance. In addition, another question I wanted to ask - does this also mean that I should NOT check in the mdf or ldf files that are created from Visual Studio? Thanks for any help and additional insight. Always appreciated.

  • Firebird 2.5 Database Corrupt

    - by BrendanH
    We have an issue where a database hangs the server when: a backup is performed (Hangs on a specific table) selecting * or count(1) from a specific table or viewing data that is related to the table (FKs, etc) We could browse the table to a certain point (using IBExpert) however after about 2900 records the machine just spikes and hangs. Performing a gfix -m does not work, and the validation reports back Record level errors = 4 (no matter how many times we run gfix -m, -v, etc. The Firebird.log file reports back these types of messages: Relation has 91631 orphan backversions (9214273 in use) in table BINS (137) - {Which is apparently just a warning} Unable to complete network request to host "MHPLZA1". Error reading data from the connection. INET/inet_error: read errno = 10054 SERVER/process_packet: broken port, server exiting Shutting down the server with 1 active connection(s) to 1 database(s), 0 active service(s) - {If we leave the backup to run while hanging, it eventually logs this error message} The setup is: The table is question has about 7000 records. The Firebird version is 2.5 Classic Server x64 install. The OS is Windows Server 2008. This is a virtual machine (VMWare) running on a massive server. (Does anyone have issues with VMs and Firebird?). We have the same setup running fine on other servers (However they are not virtual machines). Is there anyway to pin point the issue and or the cause?

  • Computer specs for a large database

    - by SpeksETC
    What sort of computer specs (CPU, RAM, disk speed) should I use for running queries on a database of 200+ million records? The queries are for a research project, so there is only one "user" and only one query will be running at a time. I tried it on my own laptop with SQL Server with an i3 processor, 2GB RAM, 5400 RPM disk and a simple query didn't finish even after 8+ hours. I have an option to connect a SSD via eSata and upgrade to 4GB RAM, but not sure if this will be enough... Thanks! Edit: The database is about 25 GB and the indexes are not setup properly. When I tried to add an index, I let it run for about 8 hours and it still hadn't finished so I gave up. Should I have more patience :)? In general, the queries will run once in a while and its ok even if it takes a couple hours to complete.... Also, the queries will produce probably about 10 million records which I need to process using Stata/Matlab and I'm concerned that my current laptop is not strong enough, but unsure of the bottleneck....

  • Users database empty after Samba3 to Samba4 migration on different servers

    - by ouzmoutous
    I have to migrate a Samba 3 to a new Samba 4 server. My problem is that the database on the samba 3 server seems a bit empty. The secrets.dtb file is only 20K whereas the “pbedit -L |wc -l”command give me 16970 lines. On my Samba3 /var/lib/samba is 1,5M After I had migrate the databse (following instructions on http://dev.tranquil.it/index.php/SAMBA_-_Migration_Samba3_Samba4), “pdbedit -L” command on the new server give me only : SAMBA4$, Administrator, dns-samba4, krbtgt and nobody. So I tried to create a VM with a Samba3. I added some users, done the same things I did for the migration and now I can see the users created on the VM. It’s like users on the Samba 3 server are in a sort of cache. I already migrate the /etc/{passwd,shadow,group} files and I can see users with the “getent passwd” command. Any ideas why my users are present when I use pdbedit but the database is so empty ? The global part of my smb.conf on the Samba 3 server : [global] workgroup = INTERNET netbios name = PDC-SMB3 server string = %h server interfaces = eth0 obey pam restrictions = Yes passdb backend = smbpasswd passwd program = /usr/bin/passwd %u passwd chat = *new* %n\n *Re* %n\n *pa* username map = /etc/samba/smbusers unix password sync = Yes syslog = 0 log file = /var/log/samba/log.%U max log size = 1000 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 add user script = /usr/sbin/useradd -s /bin/false -m '%u' -g users delete user script = /usr/sbin/userdel -r '%u' add group script = /usr/sbin/groupadd '%g' delete group script = /usr/sbin/groupdel '%g' add user to group script = /usr/sbin/usermod -G '%g' '%u' add machine script = /usr/sbin/useradd -s /bin/false -d /dev/null '%u' -g machines logon script = logon.cmd logon home = \\$L\%U domain logons = Yes os level = 255 preferred master = Yes local master = Yes domain master = Yes dns proxy = No ldap ssl = no panic action = /usr/share/samba/panic-action %d invalid users = root admin users = admin, root, administrateur log level = 2

  • Error code 1005 (errno: 121) upon create table while restoring MySQL database from a dump

    - by Jonathan
    I have a linux prod machine and a Win7 64bit dev machine. My workflow includes dumping the production MySQL database on the linux machine and restoring it in my local MySQL database on the windows machine (using SQLyog). This worked fine for a long time. Following some trouble, I formatted and reinstalled my windows dev machine. Since then I'm unable to restore the db on it. I keep receiving the following error: Query: CREATE TABLE `auth_group` ( `id` int(11) NOT NULL auto_increment, `name` varchar(80) collate utf8_unicode_ci NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `name` (`name`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci Error occured at:2010-06-26 17:16:14 Line no.:30 Error Code: 1005 - Can't create table 'ap_site.auth_group' (errno: 121) Notice that this is the first create table statement in the sql dump file. This error occurs both on MySQL Community Server 5.1.41 and 5.1.48 and with SQLyog Community 8.0.4 and 8.5.1. I really don't know what's different in my configuration from before the reinstall and now and why does it have this effect. Restoring from sql dump is something I need to keep on doing, so I need a permanent fix and not a tailored workaround.

  • Database mirroring login failure attempts on mirror server

    - by Chandan
    I have configured database mirroring between two servers at a distance 40 miles away from each other. Server specifications: SQL Server 2008,Standard Edition 64-bit This is same for principal,mirror and witness. The configuration is high-safety with automatic failover Initially we tested our .net application(web application) on both the principal and mirror and made sure that the login is not orpahned. Things run fine generally.But sometimes on the mirror server,I see login failed attempts: Login failed for user 'd0main\user'. Reason: Failed to open the explicitly specified database. [CLIENT: xx.xx.x.x] Message Error: 18456, Severity: 14, State: 38. This error appears 3-4 times a day but not more than that. My question to the experts is:If the principal is alive so why the application tries to connect to mirror.The default time-out for a .net webpage is 30 seconds,so is it possible that the application tries to connect principal and after 30 seconds even if principal is alive,it assumes that it is dead and thus tries to open a connection to mirror where it fails. Please help me with this problem.
