• Recalling import in module

  - by Isaiah

  I'm still learning python and after playing around with pygame I noticed I'm re-importing things in modules I'm importing that I've already imported. import pygame For instance I have some classes in a separate file, but I must also import pygame into that file too for them to work. Does it actually import the code twice? Will it slow down my program? Or does it just pull the same import from before, but if it does that, why would I need to import it? Is there anything like (load) in lisp that just pulls in the code like it is part of the main file? Thank You

• How to access Dispatcher in Silverlight tests?

  - by bluebit

  I am using the SL unit test framework for tests (http://code.msdn.microsoft.com/silverlightut). My code is heavily client-server communications dependant, and I access the GUI dispatcher in several places to make sure important data is only accessed on a single thread (ie. the GUI thread). This dispatcher seems unavailable in the unit tests - I have tried using Deployment.Current.Dispatcher and even created an instance of a blank control to try use its own dispatcher, but both don't work. The code inside of Dispatcher.BeginInvoke() just never executes, even if I include a Thread.Sleep afterwards.

• StructureMap 'conditional singleton' for Lucene.Net IndexReader

  - by Gareth D

  I have a threadsafe object that is expensive to create and needs to be available through my application (a Lucene.Net IndexReader). The object can become invalid, at which point I need to recreate it (IndexReader.IsCurrent is false, need a new instance using IndexReader.Reopen). I'd like to able to use an IoC container (StructureMap) to manage the creation of the object, but I can't work out if this scenario is possible. It feels like some kind of "conditional singleton" lifecycle. Does StructureMap provide such a feature? Any alternative suggestions?

• One regular expression to match parts in various positions

  - by richsage

  Hi all, I'm trying to parse a DSN (from a Symfony application) using regular expressions, in order to link with a secondary application, but using the same database. The DSN I currently have is: mysql:dbname=my_db_name;host=localhost with a regex of: /^(\w+):(dbname=(\w+))?;?(host=(\w+))?/ (using preg_match()). This matches OK, but fails in my test environment because the DSN elements are switched around, thus: mysql:host=localhost;dbname=my_testdb_name I could just switch them round, yes :-) but I'm sure that extraction of the host and dbname parts from both DSNs is possible with a single regular expression, and I'd like to be able to enhance my knowledge at the same time ;-) Is there a way I can do this?

• Multiple resultsets from Oracle in Odp.net,without refcursors

  - by James L

  SQL Server is able to return the results of multiple queries in a single round-trip, e.g: select a, b, c from y; select d, e, f from z; Oracle doesn't like this syntax. It is possible to use reference cursors, like this: begin open :1 for select count(*) from a; open :2 for select count(*) from b; end; However, you incur a penalty in opening/closing cursors and you can hold database locks for an extended period. What I'd like to do is retrieve the results for these two queries in one shot, using Odp.net. Is it possible?

• jQuery: how to pick unique IDs ?

  - by Seerumi

  Hello. New to whole this jQuery (and javascript altogether, heh) and so far it's been excellent, but now I'm in a small pickle. Let's say I have list of forms generated from SQL database and every single one of them has to have unique id, so how I can select the specific item that is to be manipulated (changing values via php). the $("#submit").click(function()) will trigger every submit buttons on the page, so how I can the #submit to be some random id that I clicked. There might be a smarter way, but I'm new to this so try to bear with me. thought of passing the unique value with onClick="myfunction(unique_id)", but don't know how it goes with jQuery. hope this made any sense

• how to combine changes tracked from several documents

  - by Jessica

  I tried to search the solution in internet, but found nothing, is there anyone who can help me? For my application, there is one document (Microsoft word), and this document is reviewed by several people in the "Track changes" mode, so the input to my application is the original document and the reviewed documents with changes (like insert/delete/comments). By this link , I know how to extract all the changes from the reviewed documents. what i want is to combine all the changes from all the reviewed documents into ONE document, and make all the changes "accepted", so the output of my application is one modified Microsoft document with all the changes (delete/insert/comment) accepted. My problem is that I don't know how to combine the changes from several documents into one single document. Anyone has an idea how to do this? Thank you very much in advance.

• inconsistency between Sun JRE javac and Eclipse java compiler?

  - by Jason S

  This confuses me. The following compiles fine under Eclipse. package com.example.gotchas; public class GenericHelper1 { static <T> T fail() throws UnsupportedOperationException { throw new UnsupportedOperationException(); } /** * just calls fail() * @return something maybe */ public boolean argh() { return fail(); } public static void main(String[] args) { // TODO Auto-generated method stub } } But if I try to do a clean build with ant, or at the command line with javac, I get this: src\com\example\gotchas\GenericHelper1.java:14: type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds boolean,java.lang.Object public boolean argh() { return fail(); } ^ 1 error what gives, and how do I fix it?

• Can't return nil, but zero value of slice

  - by Sergi

  I am having the case in which a function with the following code: func halfMatch(text1, text2 string) []string { ... if (condition) { return nil // That's the final code path) } ... } is returning []string(nil) instead of nil. At first, I thought that perhaps returning nil in a function with a particular return type would just return an instance of a zero-value for that type. But then I tried a simple test and that is not the case. Does anybody know why would nil return an empty string slice?

• How do I design a web service (microsoft) that can be consumed by multiple end points?

  - by Ben McCormack

  My company is planning to implement a solution in multiple applications that will help to validate mailing addresses at the point of data entry. We're using UPS's Extended Address Validation (XAV) web service API to validate the addresses. Our current plan is to build a .NET web service that can be used to communicate between our applications and the UPS API. We have applications in VB6, classic ASP, and .NET 2.0, so we'd like to implement a solution that can be easily consumed by each of these programming environments. What are our (Microsoft) options for designing a web service that can be consumed by multiple clients? In particular, is there a way to design a single web service that can respond with JSON (in case we want to validate our web page using javascript) in addition to XML? I'm new to designing web services and want to make sure we consider all of our options. I've heard terms like asmx, WCF, OData, etc., but I don't know which frameworks will support what we're trying to do and where to start.

• Branch structure for a web site

  - by steve_d

  I was recently reading the TFS Branching Guide and it suggests a branch for every release. For a web site, there is only one "version" released at a time. In that case is it appropriate to have a single "Production" branch? Then, during the process of preparing for a release, you merge changes from the Main branch into Production. (As opposed to the suggestion to branch each release.) If you need to do a hotfix, do it in the Production branch, then reverse integrate into Main. Doing it this way allows you to keep configuration files for Production intact in the Production branch.

• Better Java method Syntax? Return early or late? [closed]

  - by Gandalf

  Duplicate: Should a function have only one return statement? and Single return or multiple return statements? Often times you might have a method that checks numerous conditions and returns a status (lets say boolean for now). Is it better to define a flag, set it during the method, and return it at the end : boolean validate(DomainObject o) { boolean valid = false; if (o.property == x) { valid = true; } else if (o.property2 == y) { valid = true; } ... return valid; } or is it better/more correct to simply return once you know the method's outcome? boolean validate(DomainObject o) { if (o.property == x) { return true; } else if (o.property2 == y) { return true; } ... return false; } Now obviously there could be try/catch blocks and all other kinds of conditions, but I think the concept is clear. Opinions?

• How to change input button image using CSS?

  - by Baltimark

  So, I can create an input button with an image using <INPUT type="image" src="/images/Btn.PNG" value=""> But, I can't get the same behavior using CSS. for instance, i've tried <INPUT type="image" class="myButton" value=""> where "myButton" is defined in the css file as .myButton{ background:url(/images/Btn.PNG) no-repeat; cursor:pointer; width: 200px; height: 100px; border: none; } If that's all I wanted to do, I could use the original style, but I want to change the button's appearance on hover (using a myButton:hover class). I know the links are good because I've been able to load them for a background image for other parts of the page (just as a check). I found examples on the web of how to do it using javascript, but I'm looking for a css solution. I'm using Firefox 3.0.3 if that makes a difference. Thanks

• What is the most efficient way to delete all selected items in a ListViewItem collection

  - by Andrew

  My user is able to select multiple items in a ListView collection that is configured to show details (that is, a list of rows). What I want to do is add a Delete button that will delete all of the selected items from the ListViewItem collection associated with the ListView. The collection of selected items is available in ListView.SelectedItems, but ListView.Items doesn't appear to have a single method that lets me delete the entire range. I have to iterate through the range and delete them one by one, which will potentially modify a collection I'm iterating over. Any hints? Edit: What I'm basically after is the opposite of AddRange().

• ASP.NET MVC - how to modify requested URLs?

  - by Marek

  The baidu spider seems to be adding ¤ to end of some crawled urls (it seems that it happens with urls containing single unicode character as the last character) The baidu-requested url looks like this: site.com/abc/ä¤ while site.com/abc/ä is the valid url and as linked from many places on my site. The internal problem is that a different route is matched for this kind of url and an unhandled exception occurs. I would not like to lose baidu because of too many 500 errors on the site. I would like to change the requested URL to a different URL by removing the added character before any ASP.NET MVC processing of the request starts. Can I write a request filter/http module or something similar in ASP.NET MVC to remove the trailing '¤' from the urls? I would not like to alter my routes to counter-hack this behavior.

• Suggestions for a C++ IDE?

  - by AedonEtLIRA

  I know this is is a shifty question and really isn't easy to answer, but bare with me. For a while now I have been using Eclipse and doing Java programming. Now that I reach a point where I'm comfortable in Java, I wish to move on back into C++ and actually make something more than a single class that prints to terminal; and work in OpenGL :). So I wonder if anybody has a recomendation of IDE's that resemble or are as fluid as Eclipse? I am aware that Eclipse has a C++ plugin, but it really doesn't feel user friendly (at least to a pampered java programmer!). I have (I think I still have it?) a copy of Visual Studio 2005, but want to see if anyone has any better ideas. Thanks ~Aedon

• Prims vs Polys: what are the pros and cons of each?

  - by Richard Inglis

  I've noticed that most 3d gaming/rendering environments represent solids as a mesh of (usually triangular) 3d polygons. However some examples, such as Second Life, or PovRay use solids built from a set of 3d primitives (cube, sphere, cone, torus etc) on which various operations can be performed to create more complex shapes. So my question is: why choose one method over the other for representing 3d data? I can see there might be benefits for complex ray-tracing operations to be able to describe a surface as a single mathematical function (like PovRay does), but SL surely isn't attempting anything so ambitious with their rendering engine. Equally, I can imagine it might be more bandwidth-efficient to serve descriptions of generalised solids instead of arbitrary meshes, but is it really worth the downside that SL suffers from (ie modelling stuff is really hard, and usually the results are ugly) - was this just a bad decision made early in SL's development that they're now stuck with? Or is it an artefact of what's easiest to implement in OpenGL?

• How to add indexes to MySQL tables?

  - by Michael

  I've got a very large MySQL table with about 150,000 rows of data. Currently, when I try and run SELECT * FROM table WHERE id = '1'; the code runs fine as the ID field is the primary index. However, recently for a development in the project, I have to search the database by another field. For example SELECT * FROM table WHERE product_id = '1'; This field was not previously indexed, however, I've added it as an index but when I try to run the above query, the results is very slow. An EXPLAIN query reveals that there is no index for the product_id field when I've already added one and as a result the query takes any where from 20 minutes to 30 minutes to return a single row. EDIT: My full EXPLAIN results are: | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+------+----------------------+------+---------+------+------+------------------+ | 1 | SIMPLE | table | ALL | NULL | NULL | NULL | NULL | 157211 | Using where | +----+-------------+-------+------+----------------------+------+---------+------+------+------------------+

• What is the correct way to bootstrap Drupal with Kohana 3?

  - by Dave

  Hi, I am trying to implement single sign on between an existing Drupal site a Kohana 3 based webapp. Ideally I would like to load Drupal's session information into $GLOBALS using the bootstap: require_once('../includes/bootstrap.inc'); drupal_bootstrap(DRUPAL_BOOTSTRAP_SESSION); A post on the Kohana forum suggested that this should be placed in Kohana's index.php, but didn't say where. I've tried right at the start, and just before Kohana's own bootstrap, but both result in a White Screen of Death. Changing the bootstrap level to DRUPAL_BOOTSTRAP_CONFIGURATION works, but the session data isn't loaded. Any bootstrap level above DRUPAL_BOOTSTRAP_ACCESS results in a WSOD. If anyone has any ideas I'd really appreciate it!

• How to have Load balanced web services sending messages with nservicebus to multiple subscribers ?

  - by Mrt

  I have load balanced web servers, that with the existing code base, handles when a user logs into the site. I would like to send a broadcast message to any applications that have subscribed saying 'hey x logged in' ? So have many web servers and many applications subscribing. How does discovery work/configuration work with nservicebus ? Should each application know about each web server and subscribe individually or is this where the distributer comes in, so web servers all send to the 1 distributer and all application subscribe to single distributer and the distributer relays the message ? I've tried to research this, but having troubles. Thanks MrT

• Retractable button bar using animations

  - by AndroidDev

  I want to create a button bar that is retractable: when the user clicks on a special "handle" button, the button bar should slide out of view partially so only the handle remains visible. When the bar is in retracted state only the handle is visible. Clicking on the handle should "slide out" the button bar so it is completely visible again. Ideally, the bar would start out in retracted state. I have tried some approaches using TranslateAnimation, including using a layout animation or calling "View.startAnimation" when the handle is clicked, but no luck so far. Do you guys have any tips how to approach this? Is there any decent documentation out there regarding Android animations? The documentation I find is sketchy at best. For instance, I found examples that cause a view to slide into view automatically using TranslateAnimation and a LayoutAnimationController when calling "addView", but when I call removeView no animation seems to be triggered at all, even if I set an animation that should create the opposite motion.

• Java generics question

  - by user247866

  So I have 3 classes. Abstract class A Class B extends class A independent Class C In class D that contains the main method, I create a list of instances of class B List<B> b = methodCall(); // the method returns a list of instances of class B Now in class C I have one method that is common to both A and B, and hence I don't want to duplicate it. I want to have one method that takes as input an instance of class A, as follows: public void someMethod(List<A> a) However, when I do: C c = new C(); c.someMethod(b); I get an error that some-method is not applicable for the argument List<B>, instead it's expecting to get List<A>. Is there a good way to fix this problem? Many thanks!

• .NET Web Service Proxy is adding special characters in XML

  - by xkingpin

  My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes

• Showing renames in hg log?

  - by Ryan Thompson

  I know that Mercurial can track renames of files, but how do I get it to show me renames instead of adds/removes when I do hg log? For instance, instead of: A bin/extract-csv-column.pl A bin/find-mirna-binding.pl A bin/xls2csv-separate-sheets.pl A lib/Text/CSV/Euclid.pm R src/extract-csv-column.pl R src/find-mirna-binding.pl R src/modules/Text/CSV/Euclid.pm R src/xls2csv-separate-sheets.pl I want some indication that four files have been moved. I think I read somewhere that the output is like this to preserve backward-compatibility with something-or-other, but I'm not worried about that.
