• Checking Drupal authentication from external PHP

  - by peppergrower

  This may well be simple, but I'm new to Drupal. The organization I work for switched to Drupal a little while ago, but there's still some legacy code in various external PHP files that would be cumbersome to convert over to work within Drupal. However, it would be very nice to be able to restrict access to some of these pages based on a person being authenticated against Drupal. (Some pages are administrative and are currently visible to anyone who knows the URL, for instance. Yes, poor design, but that's what I inherited...) How can I check with Drupal, from an external PHP file, to see if the person visiting a given page has authenticated?

• Accumulate 2D Array by Index

  - by Tegan Snyder

  I have an array that looks like this: Array ( [0] => Array ( [amount] => 60.00 [store_id] => 1 ) [1] => Array ( [amount] => 40.00 [store_id] => 1 ) [2] => Array ( [amount] => 10.00 [store_id] => 2 ) ) What would be a good method to reduce the array to a similar array that totals the 'amount' related to a store_id. For Instance I'd like to get this: Array ( [0] => Array ( [amount] => 100.00 [store_id] => 1 ) [2] => Array ( [amount] => 10.00 [store_id] => 2 ) )

• WCF Client Proxy State

  - by RemotecUk

  Hi, how do I test the state of my proxy before making calls to my WCF service. I have a duplex channel created using a duplex channel factory. Before making any calls to the server I want to check the state of the proxy object created from the channel factory. I saw this in a book... (to be used in immediate window) ? ((ICommunicationObject)flsProxy).State But it gave this exception... Cannot obtain fields or call methods on the instance of type 'System.ServiceModel.ICommunicationObject' because it is a proxy to a remote object. Would be grateful for any ideas how this can be tested, or is it better to just catch exceptions. Thanks.

• Deploying spring message driven pojo on weblogic 8.1

  - by Igman

  Hello, I am trying to deploy a spring message message driven POJO on weblogic 8.1. It is a simple POJO, and it works fine being run outside of an application server, but the messages do not seem to be picked up at all. I have created empty home and remote interfaces, as well as a container bean class that contains an instance of the pojo which it gets from the application context. I then added this container bean class to the ejb-jar.xml as a . I have not been able to get the messages pick up. Does anyone have any suggestions as to what I am doing wrong? Could anyone point me to a tutorial on how to deploy a MDP? Thanks.

• __getattr__ on a module

  - by Matt Joiner

  How can implement the equivalent of a __getattr__ on a class, on a module? Example When calling a function that does not exist in a module's statically defined attributes, I wish to create an instance of a class in that module, and invoke the method on it with the same name as failed in the attribute lookup on the module. class A(object): def salutation(self, accusative): print "hello", accusative def __getattr__(mod, name): return getattr(A(), name) if __name__ == "__main__": salutation("world") Which gives: matt@stanley:~/Desktop$ python getattrmod.py Traceback (most recent call last): File "getattrmod.py", line 9, in <module> salutation("world") NameError: name 'salutation' is not defined Evidently something is not right about my assumed implementation.

• Writing a blocking wrapper around twisted's IRC client

  - by Andrey Fedorov

  I'm trying to write a dead-simple interface for an IRC library, like so: import simpleirc connection = simpleirc.Connect('irc.freenode.net', 6667) channel = connection.join('foo') find_command = re.compile(r'google ([a-z]+)').findall for msg in channel: for t in find_command(msg): channel.say("http://google.com/search?q=%s" % t) Working from their example, I'm running into trouble (code is a bit lengthy, so I pasted it here). Since the call to channel.__next__ needs to be returned when the callback <IRCClient instance>.privmsg is called, there doesn't seem to be a clean option. Using exceptions or threads seems like the wrong thing here, is there a simpler (blocking?) way of using twisted that would make this possible?

• How to post Arabic characters in PHP

  - by Peter Stuart

  Okay, So I am writing an OpenCart extension that must allow Arabic characters when posting data. Whenever I post ????? the print_r($_POST) returns with this: u0645u0631u062du0628u0627 I check the HTML header and it has this: <meta charset="UTF-8" /> I checked the PHP file that triggers all SQL queries and it has this code: mysql_query("SET NAMES 'utf8'", $this->link); mysql_query("SET CHARACTER SET utf8", $this->link); mysql_query("SET CHARACTER_SET_CONNECTION=utf8", $this->link); This is in my form tag: <form action="<?php echo $action; ?>" method="post" enctype="multipart/form-data" id="form" accept-charset="utf-8"> I can't think of what else I am doing wrong. The rest of the OpenCart framework supports UTF8 and arabic characters. It is just in this instance where I can't post anything arabic? Could someone please help me? Many Thanks Peter

• Cloud Agnostic Architecture?

  - by Dave

  Hi, I'm doing some architecture work on a new solution which will initially run in Windows Azure. However I'd like the solution (or at least the architecture/design) to be Cloud Agnostic (to whatever extent is realistic). Has anyone done any work on this front or seen any good white papers/blog posts? Our highlevel architecture will consist of a payload being sent to a web service (WCF for instance), this will be dumped on a queue (for arguments sake) and a worker process will grab messages off this queue and proccess them. There will be a database of customer information which we'd ideally like to keep out of the cloud however there are obvious performance considerations. Keen to hear other's thoughts. Cheers Dave

• How the return type is determined in a method that uses Linq2Sql?

  - by Richard77

  Hello, I've usually have difficulties with return types when it comes to linq. I'll explain by the following examples. Let's say I have a Table Products with ProductID, Name, Category, and Price as columns : 1) IQueryable<Product public IQueryable<Product> GetChildrenProducts() { return (from pd in db.Products where pd.Category == "Children" select pd); } 2) Product public Product GetProduct(int id) { return (from pd in db.Products where pd.ProductID == id select pd).FirstOrDefault(); } Now, if I decide to select, for instance, only one column (Price or Name) or even 2 or 3 columns (Name and Price), but in any case, less than the 4 columns, what's going to be the return type? I mean this: public returnType GetSomeInformation() { return (from pd in db.Products select new { pd.Name, pd.Price } } What SHOULD BE the returnType for the GetSomeInformation()? Thanks for helping

• JPA entitymanager remove operation is not performant

  - by Samuel

  When I try to do an entityManager.remove(instance) the underlying JPA provider issues a separate delete operation on each of the GroupUser entity. I feel this is not right from a performance perspective, since if a Group has 1000 users there will be 1001 calls issued to delete the entire group and itr groupuser entity. Would it make more sense to write a named query to remove all entries in groupuser table (e.g. delete from group_user where group_id=?), so I would have to make just 2 calls to delete the group. @Entity @Table(name = "tbl_group") public class Group { @OneToMany(mappedBy = "group", cascade = CascadeType.ALL, fetch = FetchType.LAZY) @Cascade(value = DELETE_ORPHAN) private Set<GroupUser> groupUsers = new HashSet<GroupUser>(0);

• Alternative to COM blind aggregation in .NET for class with private interface

  - by Philip

  When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

• Regex to validate SMTP Responses?

  - by Alix Axel

  I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with(out) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to come up with: ^(220(250(334(235(250(354(250(221)?)?)?){0,})?){0,2})?)?$ Which, besides only matching authenticated connections, has some bugs... For instance, it matches: 220250334235250354250221 220250334334235250354250221 I've also tried the following modification: ^(220(250)?)?((334(235)?){2})?(250(354(250(221)?)?)?){0,}$ This one accepts non-authenticated responses but it fails to match 220250334 and wrongly matches 220250334334235250354250221 (at least 2 250 are needed before the 354 response code). Can someone help me out with this? Thanks in advance.

• Can I use ANTLR for both two-way parsing/generating?

  - by Mike Q

  Hi all, I need to both parse incoming messages and generate outgoing messages in EDIFACT format (basically a structured delimited format). I would like to have a Java model that will be generated by parsing a message. Then I would like to use the same model to create an instance and generate a message. The first half is fine, I've used ANTLR before to go from raw - Java objects. But I've never done the reverse, or if I have it's been custom. Does ANTLR support generating using a grammar or is it really just a parse-only tool?

• Setting up a SQL Membership Provider and attaching the MDF file in Visual Studio 2008

  - by aubreyrhodes

  I'm trying to set up a SQL Membership Provider for an ASP.NET MVC 1.0 and I'm having problems setting up the tables and stored procedures in the database. I've tried attaching both the applications current database and a blank database to my local SQLEXPRESS instance (using SSEUtil) and then running the aspnet_regsql wizard against them. When I detach the mdf file and try to load it in Visual Studio 2008, the data connection in the server explorer shows that the database has no tables or stored procedures. Am I missing a step or something here? I've been having a heap of trouble with compatibility between Visual Studio and SQLEXPRESS.

• Embedding a YouTube Video Based on a PHP Variable

  - by jeffpm

  I have a website that I am creating for a class project. The website shows information about bands (which is stored in a mysql database). I am trying to spruce up the site a bit, and I would like to embed a YouTube video based on the band's name. Say, for instance, I have "Led Zeppelin" stored in my database. How can I take a PHP variable containing "Led Zeppelin", search YouTube using that variable, find a random video, and then embed that in the website? From the research I've done, it seems you can only embed YouTube videos if you know the exact address of the video. Thanks!

  I am trying to secure my Flex application within my Java web application. Currently my Java web application, handles logging and managing user accounts and the like. I was wondering if there is a way to essentially share that user credentials with the Flash movie in a secure mechanism?

• How to combine elements of a list

  - by Addie

  I'm working in c#. I have a sorted List of structures. The structure has a DateTime object which stores month and year and an integer which stores a value. The list is sorted by date. I need to traverse the list and combine it so that I only have one instance of the structure per date. For example: My initial list would look like this: { (Apr10, 3), (Apr10, 2), (Apr10, -3), (May10, 1), (May10, 1), (May10, -3), (Jun10, 3) } The resulting list should look like this: { (Apr10, 2), (May10, -1), (Jun10, 3) } I'm looking for a simple / efficient solution. The struct is: class CurrentTrade { public DateTime date; public int dwBuy; } The list is: private List<CurrentTrade> FillList

• VB.NET ASP.NET Web Application woes (VS 2008)

  - by typoknig

  Hi all, I am making my first web application with ASP.NET and I am having a rough time. I have previously created the application I am working on as a Windows Form application and it works great, but I am having problems with the HTML side of things in the web application. My issues are pretty minor, but very annoying. I have worked with websites before and CSS, but as far as I can tell I do not have direct access to a CSS when creating a web application in VS 2008. My biggest issue is the positioning of components that I have dragged onto the "Default.aspx" form. For instance, how am I supposed to float a panel next to another one if I don't have a CSS, or how am I to correctly position a label?

• Replacement for PHP's __autoload function?

  - by Josh

  I have read about dynamically loading your class files when needed in a function like this: function __autoload($className) { include("classes/$className.class.php"); } $obj = new DB(); Which will automatically load DB.class.php when you make a new instance of that class, but I also read in a few articles that it is bad to use this as it's a global function and any libraries that you bring into your project that have an __autoload() function will mess it up. So does anyone know of a solution? Perhaps another way to achieve the same effect as __autoload()? Until I find a suitable solution I'll just carry on using __autoload() as it doesn't start becoming a problem until you bring in libraries and such. Thanks.

• How to tell Eclipse 3.4 WTP to not restart tomcat on JSP save?

  - by Boden

  Whenever I save a JSP file in my WTP project, Eclipse restarts its Tomcat instance. This is sorta driving me nuts. I don't want to disable auto reload completely, I just don't want it to happen when I save a file that doesn't require a restart. I'm not sure how Eclipse WTP works in this regard. Could it be my project structure? The JSP files are in WEB-INF/jsp. (this SO question is similar to mine, but doesn't have a sufficient answer) EDIT: I want auto-reloading to happen, but not for file saves that do not require it. When I save a JSP there is no reason to have Tomcat restart. Thus what I'm looking for, if possible, is a smarter way for reloading to happen.

• Shorter Binding expression with validation

  - by Andrii V

  Hi, I'm repeating same binding parameters for every textbox and they're quite long strings (which is not good for many reasons). And I'm wondering if there's a way to make them shorter? For instance all my controls on forms are using the following binding template: Text="{Binding SourceProperty, UpdateSourceTrigger=PropertyChanged, ValidatesOnExceptions=True, ValidatesOnDataErrors=True, NotifyOnValidationError=True}" I'd would like to have something shorter that ideally will take SourceProperty as parameter. Possbly like this: Text="{MyBinding SourceProperty}" or Text="{Binding SourceProperty, Params=MyParams}" One possible option would be to inherit from Binding and create new markup extension. Did someone tried this? Any other ideas how to make these repetetive bindings look better?

• Testing complex entities

  - by Carlos

  I've got a C# form, with various controls on it. The form controls an ongoing process, and there are many, many aspects that need to be right for the program to run correctly. Each part can be unit tested (for instance, loading some coefficients, drawing some diagnostics) but I often run into problems that are best described with an example: "If I click here, then here, then change this, then re-open the form, then click here, it crashes or produces an error" I've tried my best to use common code organisational ideas (inheritance, DRY, separation of concerns) but there never seems to be a way to test every single path, and inevitably, a form with several controls will have a huge number of ways to execute. What can I read (preferably online) that addresses this kind of issue, and is there a (non-generic) term for it. This isn't a specific problem I'm having, but one that creeps up on me, especially with WinForms.
