• How to run script from command-line

  - by Eric

  I want to write a script that counts the types of objects there are in the ZODB, when they were created, how many users have joined since a given point in time,etc. I am wondering how to accomplish this. So, was wondering if there is a way to pass a script to bin/instance to be executed. I've created this script with a py script but it takes a VERY long time to finish and this is why I would like to do this from the command-line... in the hopes of it running faster. Thanks ERic

• Create a Python User() class that both creates new users and modifies existing users

  - by ensnare

  I'm trying to figure out the best way to create a class that can modify and create new users all in one. This is what I'm thinking: class User(object): def __init__(self,user_id): if user_id == -1 self.new_user = True else: self.new_user = False #fetch all records from db about user_id self._populateUser() def commit(self): if self.new_user: #Do INSERTs else: #Do UPDATEs def delete(self): if self.new_user == False: return False #Delete user code here def _populate(self): #Query self.user_id from database and #set all instance variables, e.g. #self.name = row['name'] def getFullName(self): return self.name #Create a new user >>u = User() >>u.name = 'Jason Martinez' >>u.password = 'linebreak' >>u.commit() >>print u.getFullName() >>Jason Martinez #Update existing user >>u = User(43) >>u.name = 'New Name Here' >>u.commit() >>print u.getFullName() >>New Name Here Is this a logical and clean way to do this? Is there a better way? Thanks.

• Can you get access to the NumberFormatter used by ICU MessageFormat

  - by Travis

  This may be a niche question but I'm working with ICU to format currency strings. I've bumped into a situation that I don't quite understand. When using the MesssageFormat class, is it possible to get access to the NumberFormat object it uses to format currency strings. When you create a NumberFormat instance yourself, you can specify attributes like precision and rounding used when creating currency strings. I have an issue where for the South Korean locale ("ko_KR"), the MessageFormat class seems to create currency strings w/ rounding (100.50 - ?100). In areas where I use NumberFormat directly, I set setMaximumFractionDigits and setMinimumFractionDigits to 2 but I can't seem to set this in the MessageFormat. Any ideas?

• Decimal Base Conversion using PYTHON

  - by Butinyane More

  PROBLEM DESCRIPTION Given a decimal number, and a new base to represent it in. If the base is larger than 10, use capital letters for the digits(that is, A is 10, B is 11 and so forth). The decimal number given, and the new base, will both be integer values, separated by a space. The base to convert to will always be smaller than or equal to 30. Please create a program that will convert a decimal number to any base in this instance. When evaluating the program the sample input must something like: 18 2 and the program must output the following: 10010 Please i beg of you to send me a solution to this problem as soon as possible.

• How do I size a UITextView to it's content?

  - by drewh

  Is there a good way to adjust the size of a UITextView to conform to it's content? Say for instance I have a UITextView that contains one line of text: "Hello world" I then add another line of text: "Goodbye world" Is there a good way in Cocoa Touch to get the rect that will hold all of the lines in the text view so that I can adjust the parent view accordingly? As another example, look at the Notes field for events in the Calendar application--note how the cell (and the UITextView it contains) expands to hold all lines of text in the notes string.

• How do I detect the environment in Salesforce?

  - by Craig Harris

  I am integrating our back end systems with Salesforce using the web services. I have production and stage environments running on different URLs. I need to be able to have the endpoint of the web service call be different depending on whether the code is running in the production or sandbox Salesforce instance. How do I detect the environment. Currently I am considering looking up a user to see if there user name ends in 'devsandbox' as I have been unable to identify a system object that I can query to get the environment. Further clarification: The location I need to determine this is within the Apex code that is invoked when I select a button in Salesforce. My custom controller needs to know if it running in the production or sandbox Salesforce environment.

• Manually removing sql server 2008

  - by user193655

  I am not able to remove sql server 2008 from my machine. I installed it in the past as a part of the installation of an application, this installed the runtime of sql server 2008 SP0. But now I cannot uninstall. I tried to use the setup of SP0 and even of SP2 but it was not able to uninstall, by giving fatal errors when it does the preliminary checks. This means that the only option I have is format my machine? I cannot even intall a new instance, something is really corrupted. Is it a way to remove it manually?

• Visual studio winform designer shows design errors as text rather than html

  - by Miki Watts

  All of the sudden, visual studio displays designer errors as plain html text, for example: <DIV id="div1" class="ErrorStyle" width="100%"><span style="font-weight: 600"><br>Object reference not set to an instance of an object. </span><br><a href="" instead of displaying the usual html formatted. I haven't been able to find anything similar to it on google. Before getting this problem, when I tried opening the winform designer, I would get the run/save/cancel dialog of internet explorer for a .tmp file, instead of the designer window. That went away when I found out that I had notepad assigned to the .tmp file type and removed that. Any ideas how to fix this?

• ASP.NET MVC ,Maintaining Model State between Ajax requests

  - by Podders

  problem: On first full page request, my controller invokes an applicationServices Layer (Web Service Proxy to my business tier) in order to populate a collection of current services that is stored in my own controller base class property. This is then to be displayed within a view. Everything within the context of that controller has access to this "Services Collection". Now when i make further calls to the same action method via an AJAX Call, i obviously hitt a different instance of that controller meaning my services collection is empty. So other than re-getting the whole collection again, where would i store this collection so it gets persisted between ajax requests? Should i persist it as a seperate DomainModel Object, Session object?....as ViewData is not working for me obv. Excuse my MVC ignorance :) Any help would be greatly appreciated :)

• What is the release date for Rakudo Star (perl6)?

  - by kbenson

  If a specific release date is not available (as I suspect it is not), can you provide resources for tracking how close it is to the desired feature set that allows release. I'm not necessarily asking for a percentage gauge, or X of Y features completed list. A list of bugs marked in whichever section of the perl RT instance that's tracking Rakudo bugs would meet my criteria, even more so if the list is dynamic (I.e. it's a list of bugs tagged in some manner, not a static list of ticket numbers). If there are only a few planned features left to be finished/tested before it's considered ready for final testing, listing those would also be sufficient.

• C# - Removing items from lists and all references to them.

  - by LiamV

  Hi there, I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node? Much appreciated, Liam

• User Interface design books/resources for programmers

  - by mmacaulay

  Hi, I'm going to make my monthly trip to the bookstore soon and I'm kind of interested in learning some user interface and/or design stuff - mostly web related, what are some good books I should look at? One that I've seen come up frequently in the past is Don't Make Me Think, which looks promising. I'm aware of the fact that programmers often don't make great designers, and as such this is more of a potential hobby thing than a move to be a professional designer. I'm also looking for any good web resources on this topic. I subscribed to Jakob Nielsen's Alertbox newsletter, for instance, although it seems to come only once a month or so. Thanks! Somewhat related questions: http://stackoverflow.com/questions/75863/what-are-the-best-resources-for-designing-user-interfaces http://stackoverflow.com/questions/7973/user-interface-design

• Taking learning into account in a development process

  - by Thiago

  How to deal with the fact that you don't know the language/framework in a development process? For instance, suppose a group of Java developers are about to start a .NET project, they don't know the platform well and might end up finding solutions that the framework already solves or solves better. The sort of questions I have are: which are the best practices in this case? Is RTFM before going on a good pratice? When should one stop RTFM and start asking/searching/playing? Is not RTFM and just searching/asking/playing a good practice? What about estimatives? I'd like to hear from your experience :-)

• Do you have any tips for comments code to keep them in step with the code?

  - by Rob Wells

  G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code. My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?" Edit: Oops. Seems to be a duplicate of this question http://stackoverflow.com/questions/121945/how-do-you-like-your-comments so sorry for the noise. Thanks to my, seemingly, SO shadow for pointing it out - wouldn't have thought I was that interesting. Now off to read the original post and see if it is relevant. Edit: I meant to emphasise the best appraoch to ensure that your comments will stay in step with the code. Maybe expressing an intent rather than the mechansim for instance.

• Unit Testing Codeigniter Classes with fooStack - clashes

  - by DrPep

  I'm having 'fun' testing interactions in a CodeIgniter based web app. It seems when running the entire test suite "phpunit AllTests.php" it loads all of the test classes, their targets (Systems under Test) and creates a PHPUnit_Framework_TestSuite instance which presumably iterates over the classes which extend CIUnit_TestCase and runs them. The problem comes where you have multiple classes referencing another class (such as a library). As all the classes are loaded into the same process space, PHP reports "cannot redefine class xyz". Have I missed something here or doing something haenously wrong? In my test class i'm doing something like: include_once dirname(__FILE__).'/../CIUnit.php'; include_once dirname(__FILE__).'/../../libraries/ProductsService.php'; class testProductsService extends CIUnit_TestCase { public function testGetProducts_ReturnsArrayOfProducts(){ $service = new ProductsService(); $products = $service->getProducts(); $this->assertTrue(is_array($products)); } } The problem manifests as I have a controller which does: $this->load->library('ProductsService');

• dbpedia auto-suggest labels

  - by Sid

  Wikipedia has a auto-suggest feature on its search field. If you for instance type in "mars" it lists a few items including Mars, Marseille, Marsh. I am looking to implement something similar working off the latest DBpedia export (wikipedia in database form). If I do a search for all labels in the labels_en.nt file that DBpedia offer that begin with "mars" then, even if I remove ones that redirect on to others that are listed, I end up with a huge list. In trying to understand how wikipedia does this I noticed that I'm actually querying this URL which returns a JSON string. Now my problem is that I don't know how wikipedia narrows the list down. Perhaps it does so based on page popularity. The higher views/edits a page has the higher it goes in this suggestion box. If so, does DBpedia export this information?

• TabWidget Activity Handling - Does it Create a New Activity EVERY Time?

  - by stormin986

  When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order––A, B, A, C, A, B––how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?

• PHP: How to cast object to inherited class?

  - by andreyvlru

  I'd like to inherit PDOStatement class and use it in my website scripts. But I am frustrated how to get required object. PDO::query returns only direct PDOStatement object and looks like there are no other method to create PDOStatement object or inherited class. Initially i thought to move PDOStatement object to constructor of inherit class Something like that: $stmt = PDO -> query("select * from messages"); $messageCollection = new Messaging_Collection($stmt); But how to make instance of PDOStatement to inherited object (Messaging_Collection). It is a big question for me. class Messaging_Collection extends PDOStatement { public function __construct(PDOStatement $stmt) { //there i should to transform $stmt to $this // direct $this = $stmt is not possible // is there other right way? }

• WPF UserControls - setting the .Command property on button inside UserControl

  - by Judah Himango

  I've got a UserControl that contains a button and some other controls: <UserControl> <StackPanel> <Button x:Name="button" /> ... </StackPanel> </UserControl> When I create a new instance of that control, I want to get at the Button's Command property: <my:GreatUserControl TheButton.Command="{Binding SomeCommandHere}"> </my:GreatUserControl> Of course, the "TheButton.Command" thing doesn't work. So my question is: Using XAML, how can I set the .Command property of the button inside my user control?

• Detecting Requests from Mobile Browsers in ASP.NET

  - by Josh Stodola

  I have an existing web site and I would like to create a mobile version of it that is more suitable. For instance, the main site uses drop-down menus and we all know those are quite the fail on mobile devices. I would like to redirect to my mobile version (it will be a subdomain of the current site) if I detect a request from a mobile browser. So when they Google something and come to my site, they will automatically see the mobile version (just like Wikipedia). Does ASP.NET provide an easy way of doing this? If not, how can I do it?

• Extracting Text from between parentheses in PHP using preg_replace

  - by Christopher

  I am trying to take a string of text like so: $string = "This (1) is (2) my (3) example (4) text"; In every instance where there is a positive integer inside of parentheses, I'd like to replace that with simply the integer itself. The code I'm using now is: $result = preg_replace("((\d+))", "$0", $string); But I keep getting a "Delimiter must not be alphanumeric or backslash" error. Any thoughts? I know there are other questions on here that sort of answer the question, but my knowledge of regex is not enough to switch it over to this example.

• ASP.NET Nested masterpages, how to set content in the top page from the aspx file?

  - by David Suarez

  I have some content from a CMS that I need to move to raw asp.net pages. Since the templates are nested I guess I can use nested masterpages to acomplish it, but I'm finding that I can't set values on the top masterpage from the deep child page. Here is a sample. I have several nested masterpages with contentplaceholders: top master (with contentPlaceHolder1) nested master, dependent on top master (with contentPlaceHolder2) aspx page, dependent on nested master, defines content for contentPlaceHolder1 and 2 The problem is that asp.net doesn't allow me to have the value of contentPlaceHolder1 defined in the content page, it should be defined in the nested master. But the point is that the client page knows that value, not the template masters (for instance, the page knows about the graphic it has to display on the the top, but the placeholder for the graphic is the top master). How can I set values in the aspx page to be rendered in the top master?

• How to make Excel strip ALL quotes from CSV text fields

  - by Klay

  When importing a CSV file into Excel, it only strips the double-quotes from the FIRST field on the line, but leaves them on all other fields. How can I force Excel to strip the quotes from ALL strings? For instance, I have a CSV file: "text1", "text2", "numeric1", "numeric 2" "abc", "def", 123, 456 "abc", "def", 123, 456 "abc", "def", 123, 456 "abc", "def", 123, 456 I import it into Excel using Data Import External Data Import Data. I specify that the fields are delimited by commas, and that the text delimiter is the double-quote character. Both the data preview and the actual Excel spreadsheet columns only strip the double-quotes from the first text field. All other text fields still have quotes around them. What's really strange is that Access is able to import this data correctly (i.e. strips quotes from every text field. Note that this is NOT a matter of internal commas or quotes or escape characters. This happens in Excel 2003 and Excel 2007.

• Which design pattern to manage windows?

  - by Lu Lu

  Hello, I am using .NET 2.0 & C# to develop a WinForm Mdi application. It will have a Main Window and a lot of mdi windows. I am thinking I should use which design pattern to manage mdi windows. Because I want only one instance for each window, if window is existed, I will show it on top, & otherwise I will create and show it. Note: a mdi window is opened from Menus of Main Window or open from another mdi window. An example is very good. Update: Menu's status is depended on mdi window's status. Ex: If Window 'A' is openned - menu 'A' - disabled. When window 'A' is closed - I update menu 'A' status to Enabled. Thanks.

• Detect the URI encoding automatically in Tomcat

  - by Roland Illig

  I have an instance of Apache Tomcat 6.x running, and I want it to interpret the character set of incoming URLs a little more intelligent than the default behavior. In particular, I want to achieve the following mapping: So%DFe => Soße So%C3%9Fe => Soße So%DF%C3%9F => (error) The bevavior I want could be described as "try to decode the byte stream as UTF-8, and if it doesn't work assume ISO-8859-1". Simply using the URIEncoding configuration doesn't work in that case. So how can I configure Tomcat to encode the request the way I want? I might have to write a Filter that takes the request (especially the query string) and re-encodes it into the parameters. Would that be the natural way?
