<p>My $SHELL is tcsh. I want to run a C shell script that will call a program many times with some arguments changed each time. The program I need to call is in Fortran. I do not want to edit it. The program only takes arguments once it is executed, but not on the command line. Upon calling the program in the script, the program takes control (this is where I am stuck currently, I can never get out because the script will not execute anything until after the program process stops). At this point I need to pass it some variables, then after several iterations I will need to <kbd>Ctrl</kbd>+<kbd>C</kbd> out of the program and continue with the script.</p>
<p>How can this be done?</p>

<p>What is the most elegant way to calculate the previous business day in shell ksh script ?</p>
<p>What I got until now is :</p>
<pre><code>#!/bin/ksh
set -x
DAY_DIFF=1
case `date '+%a'` in
"Sun")
DAY_DIFF=2
;;
"Mon")
DAY_DIFF=3
;;
esac
PREV_DT=`perl -e '($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)=localtime(time()-${DAY_DIFF}*24*60*60);printf "%4d%02d%02d",$year+1900,$mon+1,$mday;'`
echo $PREV_DT
</code></pre>
<p>How do I make the ${DAY_DIFF} variable to be transmitted as value and not as string ?</p>

<p>So I have an Access database with a front and a back end. I will be distributing it to users soon, but I have no control over where exactly they will put the files on their computers. However, I think I can count on them putting front and back ends in the same folder.</p>
<p>As such, when the front end opens, I want it to check that the linked tables are correctly connected to the back-end database. I have working code for this; however I don't know where to put it. When the front end opens, a menu form is automatically opened (configured through the start-up dialogue box). I have put the code in the <code>OnOpen</code> event, which I thought occurred before any data is loaded, but when I test this out, I get a message telling me that the back-end cannot be found (it's looking in its old location).</p>
<p>Basically, is there an event I can use that runs before any forms have opened?</p>

<p>Can someone please point me to the easiest way to have a timer in a Win32 service?</p>
<p>I suppose I could create a dummy window for this purpose or have a second thread do tick counts, but what's best? Is there a more elegant way?</p>
<p>Thanks in advance.</p>

<p>Regarding cross-site request forgery (CSRF) attacks, if cookies are most used authentication method, why do web browsers allow sending cookies of some domain (and to that domain) from a page generated from another domain?</p>
<p>Isn't CSRF easily preventable in browser by disallowing such behavior? </p>
<p>As far as I know, this kind of security check isn't implemented in web browsers, but I don't understand why. Did I get something wrong?</p>
<p>About CSRF:</p>
<ul>
<li><a href="http://en.wikipedia.org/wiki/Csrf" rel="noreferrer">On wikipedia</a></li>
<li><a href="http://www.codinghorror.com/blog/archives/001171.html" rel="noreferrer">On coding horror</a></li>
</ul>
<p>Edit: I think that cookies should not be sent on http POST in the above case. That's the browser behavior that surprises me.</p>

<p>When I was taking CS in college (mid 80's), one of the ideas that was constantly repeated was to always write loops which test at the top (while...) rather than at the bottom (do ... while) of the loop. These notions were often backed up with references to studies which showed that loops which tested at the top were statistically much more likely to be correct than their bottom-testing counterparts.</p>
<p>As a result, I almost always write loops which test at the top. I don't do it if it introduces extra complexity in the code, but that case seems rare. I notice that some programmers tend to almost exclusively write loops that test at the bottom. When I see constructs like:</p>
<pre><code>if (condition)
{
do
{
...
} while (same condition);
}
</code></pre>
<p>or the inverse (<code>if</code> inside the <code>while</code>), it makes me wonder if they actually wrote it that way or if they added the <code>if</code> statement when they realized the loop didn't handle the null case.</p>
<p>I've done some googling, but haven't been able to find any literature on this subject. How do you guys (and gals) write your loops?</p>

<p>After much searching, I found the download for the <a href="http://sourceforge.net/project/showfiles.php?group_id=45216" rel="nofollow noreferrer">eclipse version of jalopy</a>. Is this compatible with Eclipse 3.4? It's dated 2006.</p>
<p>I've copied the extracted folder to my plugins directory and run <code>eclipse -clean</code>, but I can't find anything matching 'jalopy' in preferences.</p>
<p>If it's not compatible, are there any (free) alternatives?</p>

<p>I am trying to hide some divs before the user prints this giant form, then display the divs again afterward. Thus I want to ignore the rest of the page, and only print the form itself.</p>
<p>Sure I <em>could</em> open a separate page when the user clicks the print button. The only thing is that the form is really long and it would be quite tedious to do that.</p>
<p><br>
Edit: My previous question did not actually reflect what I was looking for. So I changed it to the current one.</p>
<p>Also thanks to all that suggested window.onbeforeprint and window.onafterprint. That was relevant to my edited question.</p>

<p>How do I extend my parent's options array for child classes in PHP?</p>
<p>I have something like this:</p>
<pre><code>class ParentClass {
public $options = array(
'option1'=>'setting1'
);
//The rest of the functions would follow
}
</code></pre>
<p>I would like to append to that options array in a child class without erasing any of the parent options. I've tried doing something like this, but haven't quite got it to work yet:</p>
<pre><code>class ChildClass extends ParentClass {
public $options = parent::options + array(
'option2'=>'setting2'
);
//The rest of the functions would follow
}
</code></pre>
<p>What would be the best way to do something like this?</p>

<p>Currently, if I want to apply a method to a group of ActiveRecord objects, I have to structure the call like so:</p>
<pre><code>messages = Message.find(:all)
csv = Message.to_csv(messages)
</code></pre>
<p>How can I define the method so it's structured like so?</p>
<pre><code>messages = Message.find(:all)
csv = messages.to_csv
</code></pre>
<p>This is the current model code:</p>
<pre><code>require 'fastercsv'
class Message < ActiveRecord::Base
def Message.to_csv(messages)
FasterCSV.generate do |csv|
csv << ["from","to", "received"]
for m in messages
csv << [m.from,m.to,m.created_at]
end
end
end
end
</code></pre>

<p>I have something here that is really catching me off guard.</p>
<p>I have an ObservableCollection of T that is filled with items. I also have an event handler attached to the CollectionChanged event.</p>
<p>When you <strong>Clear</strong> the collection it causes an CollectionChanged event with e.Action set to NotifyCollectionChangedAction.Reset. Ok, that's normal. But what is weird is that neither e.OldItems or e.NewItems has anything in it. <strong>I would expect e.OldItems to be filled with all items that were removed from the collection.</strong></p>
<p>Has anyone else seen this? And if so, how have they gotten around it?</p>
<p>Some background: I am using the CollectionChanged event to attach and detach from another event and thus if I don't get any items in e.OldItems ... I won't be able to detach from that event.</p>
<p><br></p>
<p><strong>CLARIFICATION:</strong>
I do know that the documentation doesn't <em>outright</em> state that it has to behave this way. But for every other action, it is notifying me of what it has done. So, my assumption is that it would tell me ... in the case of Clear/Reset as well.</p>
<p><br></p>
<p>Below is the sample code if you wish to reproduce it yourself. First off the xaml:</p>
<pre><code><Window
x:Class="ObservableCollection.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1"
Height="300"
Width="300"
>
<StackPanel>
<Button x:Name="addButton" Content="Add" Width="100" Height="25" Margin="10" Click="addButton_Click"/>
<Button x:Name="moveButton" Content="Move" Width="100" Height="25" Margin="10" Click="moveButton_Click"/>
<Button x:Name="removeButton" Content="Remove" Width="100" Height="25" Margin="10" Click="removeButton_Click"/>
<Button x:Name="replaceButton" Content="Replace" Width="100" Height="25" Margin="10" Click="replaceButton_Click"/>
<Button x:Name="resetButton" Content="Reset" Width="100" Height="25" Margin="10" Click="resetButton_Click"/>
</StackPanel>
</Window>
</code></pre>

<p>I currently capture MiniDumps of unhandled exceptions using <Code>SetUnhandledExceptionFilter</Code> however at times I am getting "R6025: pure virtual function".</p>
<p>I understand how a pure virtual function call happens I am just wondering if it is possible to capture them so I can create a MiniDump at that point.</p>

<p>When I add a reference to <strong>Microsoft.Office.Interop.Excel</strong> on my computer, Visual Studio adds this to the project file:</p>
<pre><code><COMReference Include="Excel">
<Guid>{00020813-0000-0000-C000-000000000046}</Guid>
<VersionMajor>1</VersionMajor>
<VersionMinor>5</VersionMinor>
<Lcid>0</Lcid>
<WrapperTool>primary</WrapperTool>
<Isolated>False</Isolated>
</COMReference>
</code></pre>
<p>There is another developer on the team who gets errors and needs to add a DLL file to the project called Interop.Excel.dll, which replaces the code above with this in the project file:</p>
<pre><code><Reference Include="Interop.Excel, Version=1.5.0.0, Culture=neutral, processorArchitecture=MSIL">
<SpecificVersion>False</SpecificVersion>
<HintPath>My Project\Interop.Excel.dll</HintPath>
</Reference>
</code></pre>
<p>This does work on my computer.</p>
<p>Could you please explain the differences between the two methods, which is best, and how to get the first one working on other computers?</p>

<p>Thanks a million everyone for everyone's response. Unfortunately, none of the solutions appear to be working on my end, and my guess is that the example I've provided is messed up.</p>
<p>So let me try again.</p>
<p>My table looks like this:</p>
<pre><code> contract project activity
row1 1000 8000 10
row2 1000 8000 20
row3 1000 8001 10
row4 2000 9000 49
row5 2000 9001 49
row6 3000 9000 79
row7 3000 9000 78
</code></pre>
<p>Basically, the query I'm looking for would return "2000,49" for "contract, activity" because only contract #2000 has one, and ONLY one, unique activity value.</p>
<p>Again, thanks a million in advance,
boroatel</p>

<p>Another poster asked about <a href="https://stackoverflow.com/questions/224138/infinite-loops-top-or-bottom">preferred syntax for infinite loops</a>.</p>
<p>A follow-up question: <i>Why</i> do you use infinite loops in your code? I typically see a construct like this:</p>
<pre><code>for (;;) {
int scoped_variable = getSomeValue();
if (scoped_variable == some_value) {
break;
}
}
</code></pre>
<p>Which lets you get around not being able to see the value of scoped_variable in the <code>for</code> or <code>while</code> clause. What are some other uses for "infinite" loops?</p>

<p>I am currently in a programming mentality that reflection is my best friend. I use it a lot for dynamic loading of content that allows "loose implementation" rather than strict interfaces, as well as a lot of custom attributes.</p>
<p>What is the "real" cost to using reflection?</p>
<p>Is it worth the effort for frequently reflected types to have cached reflection, such as our own pre-LINQ DAL object code on all the properties to table definitions?</p>
<p>Would the caching memory footprint outwieght the reflection CPU usage?</p>

</code></pre>
<p>I need to add a newline after every occurence of "@" symbol in the string.</p>

<p>I want to change the order of XML using XDocument</p>
<pre><code><root>
<one>1</one>
<two>2</two>
</root>
</code></pre>
<p>I want to change the order so that 2 appears before 1. Is this capability baked in or do I have to do it myself. For example, remove then AddBeforeSelf()?</p>
<p>Thanks</p>

<p>I have two tables, one that contains volunteers, and one that contains venues. <strong>Volunteers are assigned one venue each</strong>.</p>
<p>The id of the venues table (venues.id) is placed within the volunteers table in the venue_id column (volunteers.venue_id).</p>
<p>I know I could get a count of how many matching values are in the volunteers.venue_id column by</p>
<pre><code>SELECT venue_id, COUNT(*) FROM volunteers GROUP BY venue_id
</code></pre>
<p>Why I want to do this: so the user can go in and see how many volunteers are assigned to each venue.</p>
<p>table: volunteers -- columns: id, name, venue_id</p>
<p>table: venues -- columns: id, venue_name</p>
<p>volunteers.venue_id = venues.id</p>
<p>I know this would be a join statement of some sort so it will get a count of each venue, then match up volunteers.venue_id to venues.id and print out the venues.venue_name along with the count.</p>
<p>How would I go about joining the two tables to print out the venue name and next to it, list the count of each volunteer with that venue_id?</p>

<p>I have the following models.</p>
<pre><code># app/models/domain/domain_object.rb
class Domain::DomainObject < ActiveRecord::Base
has_many :links_from, :class_name => "Link", :as => :from, :dependent => :destroy
end
# app/models/link.rb
class Link < ActiveRecord::Base
belongs_to :from, :polymorphic => true
belongs_to :object_value, :polymorphic => true
end
</code></pre>
<p>Problem is, when I do the following, the from_type doesn't prefix the Domain namespace to the model e.g.</p>
<pre><code> Domain::DomainObject.all(:include=> :links_from )
</code></pre>
<p>That causes the following SELECT:</p>
<pre><code> SELECT `links`.* FROM `links` WHERE (`links`.`from_id` IN (5,6,12,13,18,24,25,27,29,30,31,32,34,35,39) and `links`.`from_type` = 'DomainObject')
</code></pre>
<p>The query should be:</p>
<pre><code> SELECT `links`.* FROM `links` WHERE (`links`.`from_id` IN (5,6,12,13,18,24,25,27,29,30,31,32,34,35,39) and `links`.`from_type` = 'Domain::DomainObject')
</code></pre>
<p>because Rails automatically saves the model with the namespace. </p>
<p>I've seen a few recommendations on Rails sites about doing something like this:</p>
<pre><code> belongs_to :from, :polymorphic => true, :class_name => "Domain::DomainObject"
</code></pre>
<p>However, that doesn't appear to work either. </p>
<p>So, is there a better way to do this? Or is this not supported?</p>

<p>We have just 'migrated' an SQL Server 2005 database from DEVEL into TEST. Somehow during the migration process the DB was changed from case insensitive to sensitive - so most SQL queries broke spectacularly.</p>
<p>What I would like to know, is - are there any clear benefits to having a case sensitive schema? </p>
<p>NOTE: By this I mean table names, column names, stored proc names etc. I am NOT referring to the actually data being stored in the tables.</p>
<p>At first inspection, I cannot find a valid reason that offers benefits over case insensitivity.</p>

<p>I have an Excel 2003 workbook that contains a macro to copy certain of its sheets across to a new workbook, then save and close the new workbook. It does this several dozen times, with slightly different sheet selections each time.</p>
<p>I would like to add an extra step to the macro to export the secondary workbooks' spreadsheets to PDF. The obvious way to do this would be to use a PDF printer and Excel's built in Print function, but most PDF printers give you a "Save As..." dialogue box before they finish. Obviously, typing this in individually for seventy-odd occasions lacks appeal - so I'd like something that allows me to set it ahead of time (probably "Use the filename of the file I'm printing minus its extension") then just select the default options.</p>
<p>Any ideas for a free PDF printer that does this? Or a suitable alternative?</p>

<p>I'm making a program that fits the wizard concept ideally; the user is walked through the steps to create a character for a game.</p>
<p>However, I'm realizing that the limitations of the wizard are making it difficult to design "elegant" logic flow. For example, because all pages of the wizard are initalized at the same time, I can't have the values entered in one page available to the next one. I have to put a button on each page to get the values from a previous page rather than simply having fields auto-populated.</p>
<p>I've thought about alternatives to using the wizard. I think the best idea is to have some buttons on one panel that change the information on another panel, e.g. a splitter window.</p>
<p>However, I can't find any documentation in wxPython on how to dynamically change the panel. Everything I've found so far is really pretty static, hence the use of the wizard. Even the "wxPython in Action" book doesn't mention it.</p>
<p>Are there any tutorials for making "dynamic panels" or better management of a wizard?</p>

<p>I have been trying to learn how to add testing to existing code -- currently reading reading <a href="https://rads.stackoverflow.com/amzn/click/com/0131177052" rel="noreferrer" rel="nofollow noreferrer">Working Effectively With Legacy Code</a>. I have been trying to apply some of the principles in JavaScript, and now I'm trying to extract an interface.</p>
<p>In searching for creating interfaces in JavaScript, I can't find a lot -- and what I find about inheritance seems like their are several different ways. (Some people create their own base classes to provide helpful methods to make it easier to do inheritance, some use functions, some use prototypes).</p>
<p>What's the right way? Got a simple example for extracting an interface in JavaScript?</p>

<pre><code>return __CYGWIN__;

<p>Just wondering: Is there a reason for this, or is it just some people's code styles? I would think that it makes it hard to read.</p>

<p>Is there a better/simpler way to find the number of images in a directory and output them to a variable?</p>
<pre><code>function dirCount($dir) {
$x = 0;
while (($file = readdir($dir)) !== false) {
if (isImage($file)) {$x = $x + 1}
}
return $x;
}
</code></pre>
<p>This seems like such a long way of doing this, is there no simpler way?</p>
<p><strong>Note:</strong> The isImage() function returns true if the file is an image.</p>

<p>I'm having some trouble getting log4net to work from ASP.NET 3.5. This is the first time I've tried to use log4net, I feel like I'm missing a piece of the puzzle.</p>
<p>My project references the log4net assembly, and as far as I can tell, it is being deployed successfully on my server.</p>
<p>My web.config contains the following:</p>
<pre><code> <configSections>
<section name="log4net"
type="log4net.Config.Log4NetConfigurationSectionHandler
, log4net"
requirePermission="false"/>
</configSections>
<log4net>
<appender name="InfoAppender" type="log4net.Appender.FileAppender">
<file value="..\..\logs\\InfoLog.html" />
<appendToFile value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern
value="%d [%t] %-5p %c [%x] - %m%n" />
</layout>
</appender>
<logger name="_Default">
<level value="INFO" />
<appender-ref ref="InfoAppender" />
</logger>
</log4net>
</code></pre>
<p>I'm using the following code to test the logger:</p>
<pre><code>using log4net;
using log4net.Config;
public partial class _Default : System.Web.UI.Page
{
private static readonly ILog log = LogManager.GetLogger("_Default");
protected void Page_Load(object sender, EventArgs e)
{
log.Info("Hello logging world!");
}
}
</code></pre>
<p>In my Global.asax, I'm doing the following:</p>
<pre><code>void Application_Start(object sender, EventArgs e)
{
log4net.Config.XmlConfigurator.Configure();
}
</code></pre>
<p>At this point, I can't think of what else I might be doing wrong. The directory I'm trying to store the log in is writable, and even if I try different directories I get the same result: no file, no logs.</p>
<p>Any suggestions? :-)</p>
<hr>
<p>Edit: I've tried several different formats for the path & name of the log file, some of which include "..\..\InfoLog.html", "InfoLog.html", "logs\InfoLog.html", etc, just in case someone is wondering if that's the problem.</p>
<hr>
<p>Edit: I've added the root logger node back into the log4net section, I ommitted that on accident when copying from the samples. The root logger node looks like this:</p>
<pre><code><root>
<level value="INFO" />
<appender-ref ref="InfoAppender" />
</root>
</code></pre>
<p>Even with it, however, I'm still having no luck.</p>

<p>In a <a href="https://stackoverflow.com/questions/224138/infinite-loops-top-or-bottom">coding style question about infinite loops</a>, some people mentioned they prefer the for(;;) style because the while(true) style gives warning messages on MSVC about a conditional expression being constant.</p>
<p>This surprised me greatly, since the use of constant values in conditional expressions is a useful way of avoiding #ifdef hell. For instance, you can have in your header:</p>
<pre><code>#ifdef CONFIG_FOO
extern int foo_enabled;
#else
#define foo_enabled 0
#endif
</code></pre>
<p>And the code can simply use a conditional and trust the compiler to elide the dead code when CONFIG_FOO isn't defined:</p>
<pre><code>if (foo_enabled) {
...
}
</code></pre>
<p>Instead of having to test for CONFIG_FOO every time foo_enabled is used:</p>
<pre><code>#ifdef CONFIG_FOO
if (foo_enabled) {
...
}
#endif
</code></pre>
<p>This design pattern is used all the time in the Linux kernel (for instance, include/linux/cpumask.h defines several macros to 1 or 0 when SMP is disabled and to a function call when SMP is enabled).</p>
<p>What is the reason for that MSVC warning? Additionally, is there a better way to avoid #ifdef hell without having to disable that warning? Or is it an overly broad warning which should not be enabled in general?</p>

<p>My Flash (AS3/AIR) application is currently using a slightly unusual architecture (for a Flash app) to provide particular base classes for loaded content at runtime. The external content is published with 'stub' base classes, which are eclipsed by the 'real' base classes at runtime when it is loaded. I've heard this referred to by Adobe as <em>bootstrapping</em> (<a href="http://blogs.adobe.com/flexdoc/loadingSubApps.pdf" rel="nofollow noreferrer">pdf</a>), and it has been working very well for me until now. It's not unlike a DLL architecture I believe, although I'm not qualified to say for sure.</p>
<p>Until now, the external content I have been loading has been loaded from within the same <code>SecurityDomain</code> (same sandbox), which allows me to easily load the content in a child <code>ApplicationDomain</code>. Unfortunately, as far as I can tell, an <code>ApplicationDomain</code>s that span <code>SecurityDomain</code>s cannot be related - that is, I cannot make an AppDom of one SecurityDom the child of an AppDom from another SecurityDom.</p>
<p>But now I need to load this external content from outside my Application sandbox. There are plenty of ways to achieve communication across <code>SecurityDomain</code>s - although most of them are very limited, AIR's <code>sandboxBridge</code> API is probably the most powerful. Unfortunately, none of these communication methods allow me to achieve this bootstrapping architecture. </p>
<p>I notice that the <code>LoaderContext</code> object has a <code>securityDomain</code> property, but Flash security prohibits 'local swfs' from touching it (it throws a <code>SecurityError</code> or similar).</p>
<p>Flex's <code>SWFLoader</code> has a <code>trustContent</code> property that looks promising, but I'm inclined to assume that it has the same restrictions as setting the <code>SecurityDomain</code> in the <code>Loader</code>'s <code>LoaderContext</code>.</p>
<p>I suspect I'll have to redesign (which won't be easy), but I thought I'd just check here that I've not missed something in my research.</p>
<p>So ... any ideas or pearls of wisdom? I'd especially freaking love it if someone from Adobe who works on the Security model could gimme a definitive "yes/no it can/can't be done"...</p>
<p>Thanks in advance!</p>
<p><em>Addendum:</em> I've since decided to re-design the architecture so that the bootstrapping all happens on the external domain. My question still stands, however, out of curiosity.</p>

<p>I'm currently using Subversion to manage my ASP.NET website. I'm finding that whenever I go to upload my website to my server, I'm copying a large number of hidden .svn folders and whatever contents may lie within them.</p>
<p>Does anyone have any suggestions for avoiding this? I don't particularly want those hidden .svn folders on the production server, but short of manually deleting each .svn folder before I upload my website, I'm at a loss for how to have a .svn-folder-free production environment.</p>
<hr>
<p>Edit: Thank you everyone, those are great suggestions, I really appreciate it!</p>

<p>I'm using a decimal column to store money values on a database, and today I was wondering what precision and scale to use.</p>
<p>Since supposedly char columns of a fixed width are more efficient, I was thinking the same could be true for decimal columns. Is it?</p>
<p>And what precision and scale should I use? I was thinking precision 24/8. Is that overkill, not enough or ok?</p>
<hr>
<p>This is what I've decided to do:</p>
<ul>
<li>Store the conversion rates (when applicable) in the transaction table itself, as a float</li>
<li>Store the currency in the account table</li>
<li>The transaction amount will be a <code>DECIMAL(19,4)</code></li>
<li>All calculations using a conversion rate will be handled by my application so I keep control of rounding issues</li>
</ul>
<p>I don't think a float for the conversion rate is an issue, since it's mostly for reference, and I'll be casting it to a decimal anyway.</p>
<p>Thank you all for your valuable input.</p>

<p>Today someone asked me what was wrong with their source code. It was obvious. "Use double equals in place of that single equal in that if statement. Um, I think..." As I remember some languages actually take a single equals for comparison. Since I sometimes forget or mix up the syntax details among the several languages I use, I stepped over to my laptop to try a quickie experiment.</p>
<p>It costs a bit of time and is a break in the flow to try "quick" experiments (though maybe the practice is good for memory.) What tips do you have for keeping straight in your mind the syntax (and other) details of multiple languages? </p>
<p>(And nowadays, this applies just as well to the many wiki-like markups!)</p>

<p>I'm using Microsoft WebTest and want to be able to do something similar to NUnit's <code>Assert.Fail()</code>. The best i have come up with is to <code>throw new webTestException()</code> but this shows in the test results as an <code>Error</code> rather than a <code>Failure</code>. </p>
<p>Other than reflecting on the <code>WebTest</code> to set a private member variable to indicate the failure, is there something I've missed?</p>
<p>EDIT: I have also used the <code>Assert.Fail()</code> method, but this still shows up as an error rather than a failure when used from within WebTest, and the <code>Outcome</code> property is read-only (has no public setter).</p>
<p>EDIT: well now I'm really stumped. I used reflection to set the <code>Outcome</code> property to Failed but the test <em>still</em> passes!</p>
<p>Here's the code that sets the Oucome to failed:</p>
<pre><code>public static class WebTestExtensions
{
public static void Fail(this WebTest test)
{
var method = test.GetType().GetMethod("set_Outcome", BindingFlags.NonPublic | BindingFlags.Instance);
method.Invoke(test, new object[] {Outcome.Fail});
}
}
</code></pre>
<p>and here's the code that I'm trying to fail:</p>
<pre><code> public override IEnumerator<WebTestRequest> GetRequestEnumerator()
{
this.Fail();
yield return new WebTestRequest("http://google.com");
}
</code></pre>
<p><code>Outcome</code> is getting set to <code>Oucome.Fail</code> but apparently the WebTest framework doesn't really use this to determine test pass/fail results.</p>

<p>Uhm I'm not sure if anyone has encountered this problem <br>
a brief description is on IE6 any <code><select></code> objects get displayed over any other item, even div's... meaning if you have a fancy javascript effect that displays a div that's supposed to be on top of everything (e.g: lightbox, multibox etc..) onclick of a certain element and that div overlaps a <code><select></code> your div get's to be displayed as if it's under the <code><select></code> [on this case a max and minimum z-index doesn't work ]</p>
<p>I've tried googling and found the iframe shim solution <br>
but I wanted some pretty clean alternatives
or better yet has anyone found a better solution?
since the method using iframes uses around 130mb of ram might slow down poor people's machines</p>

<p>I am new to creating Java web applications and came across this problem when trying to interact with my database (called ccdb) through my application:</p>
<p><code>java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost/ccdb/</code></p>
<p>My application runs on JBoss and uses Hibernate to interact with the MySQL database. I have the MySQL Driver in lib\mysql-connector-java-5.1.6-bin.jar of my project and I have the .jar configured in Eclipse as a "Java EE Module Dependency" so that it gets copied over to web-inf\lib\ when I deploy it to JBoss through Eclipse. I double checked and the driver is definitely in the .war file with the project, so it should be findable, right? </p>
<p>My hibernate.cfg.xml contains this line which should point hibernate to the driver.</p>
<p><code><property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property></code></p>
<p>Does anyone know what I need to do to get this to work? Do I have to configure the MySQL database as a JBoss datasource for it to work?</p>
<p>Thanks in advance.</p>
<p>Edit: kauppi's solution works, but I would prefer to have it in lib\ with the other jars, and I'm really curious as to why it won't work that way. Any ideas...?</p>

<p>I wonder if is possible to use FTS with LINQ using .NET Framework 3.5. I'm searching around the documentation that I didn't find anything useful yet.</p>
<p>Does anyone have any experience on this?</p>

<p>There are some good examples on how to calculate word frequencies in C#, but none of them are comprehensive and I really need one in VB.NET.</p>
<p>My current approach is limited to one word per frequency count. What is the best way to change this so that I can get a completely accurate word frequency listing?</p>
<pre><code>wordFreq = New Hashtable()
Dim words As String() = Regex.Split(inputText, "(\W)")
For i As Integer = 0 To words.Length - 1
If words(i) <> "" Then
Dim realWord As Boolean = True
For j As Integer = 0 To words(i).Length - 1
If Char.IsLetter(words(i).Chars(j)) = False Then
realWord = False
End If
Next j
If realWord = True Then
If wordFreq.Contains(words(i).ToLower()) Then
wordFreq(words(i).ToLower()) += 1
Else
wordFreq.Add(words(i).ToLower, 1)
End If
End If
End If
Next
Me.wordCount = New SortedList
For Each de As DictionaryEntry In wordFreq
If wordCount.ContainsKey(de.Value) = False Then
wordCount.Add(de.Value, de.Key)
End If
Next
</code></pre>
<p>I'd prefer an actual code snippet, but generic 'oh yeah...use this and run that' would work as well.</p>

<p>I want to know how events are used in embedded system code.</p>
<p>Main intention is to know how exactly event flags are set/reset in code. and how to identify which task is using which event flag and which bits of the flag are getting set/reset by each task.</p>
<p>Please put your suggestion or comments about it.</p>
<p>Thanks in advance.</p>
<hr>
<p>(edit 1: copied from clarification in answer below)</p>
<p>Sorry for not specifying the details required. Actually I am interested in the analysis of any application written in C language using vxworks/Itron/OSEK OS. For example there is eventLib library in vxworks to support event handling. I want to know that how one can make use of such system routines to handle events in task. What is event flag(is it global/local...or what ?), how to set bits of any event flag and which can be the possible relationship between task and event flags ??</p>
<p>How task can wait for multiple events in AND and OR mode ??
I came across one example in which the scenario given below looks dangerous, but why ??</p>
<pre><code> Scenarios is ==> *[Task1 : Set(e1), Task2 : Wait(e1) and Set(e2), Task3 : Wait(e2) ]*
</code></pre>
<p>I know that multiple event flags waited by one task or circular dependency between multiple tasks(deadlock) are dangerous cases in task-event relationship, but how above scenario is dangerous, I am not getting it....Kindly explain.</p>
<pre><code> (Are there any more such scenarios possible in task-event handling which should be reviewed in code ?? )
</code></pre>
<p>I hope above information is sufficient ....</p>

<p>I am reading over the K&R book, and am a little stuck.</p>
<p>What is wrong with the following?</p>
<pre><code>void getInput(int* output) {
int c, i;
for(i=0; (c = getchar()) != '\n'; i++)
output[i] = c; // printf("%c", c) prints the c value as expected
output[++i] = '\0';
}
</code></pre>
<p>When I run the program it never gets out of the loop and I have to <kbd>Ctrl+C</kbd> to exit. However if I replace the fifth line with <code>printf("%c", c);</code>, it prints out all the input just fine after hitting enter and creating the new line.</p>

<p>I'm considering altering some tables to use nvarchar(50) as primary key instead of an int primary key. Using an int ID for a key really is irrelevant data, it's the string I'm interested in. What sort of performance hit will occur, or where do you research this? Other than cut and try that is.</p>

<p>i have a 3 column datafile and i wanted to use splot to plot the same.
But what i want is that gnuplot plots first row (in some colour, say red) and then pauses for say 0.3 secs and then moves on to plotting next row (in other colour, not in red, say in green), pauses for 0.3 secs and then proceeds to next row....so on n so forth.</p>
<p>Any help will be greately appreciated.</p>
<p>thanks in advance</p>
<p>Regards Pankaj</p>

<p>I'm trying to program ARM using Eclipse + CDT + yagarto (gnu toolchain) + OpenOCD. In several sample projects (from yagarto site for example) I found linker scripts (*.ld) where a lot of linking information specified (along with sections definitions). Actually I haven't faced this files before (IAR doesn't need them), and I find them somewhat difficult to understand from a first glance. So my question is can I use one single such script file for my target processor (STR710FZ2T6) with all my projects or I have to get familiar in writing this scripts and write them for each project. If I can use single file for all projects for particular target processor can you please advice where I can find such universal one.</p>

<p>Recently I wrote an extremely basic Java Swing program with a couple of text fields and buttons. The program works fine for me on Ubuntu with Java 1.5. But when I try to run it on OSX (10.4), the main window is displayed correctly but the program seems unresponsive. Nothing seems to happen, no matter which button I click on.</p>
<p>I know next to nothing about Mac OSX, so is there something I might be doing wrong?</p>

<pre><code>Double out = otherTypes.someMethod(c, c2);
assertEquals((Double)-1.0D, out);
</code></pre>
<p>I get error "Double cannot be resolved" (the Double in assertEquals), is there any way to hack around it except extracting variable?</p>
<p>Is this bug in Java or just very usefull feature that wont be fix?</p>

<p>I implemented a small OOP library in Lua, and two things are not quite right yet. I need your advice!</p>
<h2>How to call super()?</h2>
<p>I need to make a choice. The three arguments I need to resolve a call to super() are:</p>
<ul>
<li>The class from where the call is being made (CallerClass)</li>
<li>The instance to be passed (self)</li>
<li>The name of the method (method)</li>
</ul>
<p>I hesitate between these three forms:</p>
<pre><code>--# Current way:
self:super(CallerClass):method()
--# Variant, which I now find cleaner:
CallerClass:super(self):method()
--# Python style, which is nice too:
super(CallerClass, self):method()
</code></pre>
<p>Which one looks nicer and or easier to remember to you?</p>
<h2>Do I need a Class symbol?</h2>
<p>In the current version, the only concept is a table named <code>Object</code>, which you can subclass. I have another version where I introduced a Class symbol.</p>
<p>Its use is to tell instances from classes. I.e. :</p>
<pre><code>assert(Object:isKindOf(Class))
local object = Object:new()
assert(not object:isKindOf(Class))
</code></pre>
<p>I find it very handy to document and enforce that a method must be called from a class, by starting the method with:</p>
<pre><code>assert(self:isKindOf(Class))
</code></pre>
<p>Is it usefull in Lua? What do you think? Thanks!</p>

<p>Hi Guys could you please help me refactor this so that it is sensibly pythonic.</p>
<pre><code>import sys
import poplib
import string
import StringIO, rfc822
import datetime
import logging
def _dump_pop_emails(self):
self.logger.info("open pop account %s with username: %s" % (self.account[0], self.account[1]))
self.popinstance = poplib.POP3(self.account[0])
self.logger.info(self.popinstance.getwelcome())
self.popinstance.user(self.account[1])
self.popinstance.pass_(self.account[2])
try:
(numMsgs, totalSize) = self.popinstance.stat()
for thisNum in range(1, numMsgs+1):
(server_msg, body, octets) = self.popinstance.retr(thisNum)
text = string.join(body, '\n')
mesg = StringIO.StringIO(text)
msg = rfc822.Message(mesg)
name, email = msg.getaddr("From")
emailpath = str(self._emailpath + self._inboxfolder + "\\" + email + "_" + msg.getheader("Subject") + ".eml")
emailpath = self._replace_whitespace(emailpath)
file = open(emailpath,"wb")
file.write(text)
file.close()
self.popinstance.dele(thisNum)
finally:
self.logger.info(self.popinstance.quit())
def _replace_whitespace(self,name):
name = str(name)
return name.replace(" ", "_")
</code></pre>
<p>Also in the _replace_whitespace method I would like to have some kind of cleaning routine which takes out all illegal characters which could cause processing.</p>
<p>Basically I want to write the email to the inbox directory in a standard way.</p>
<p>Am i doing something wrong here?</p>

<p>I have a composite control that adds a TextBox and a Label control to its Controls collection. When i try to set the Label's AssociatedControlID to the ClientID of the Textbox i get this error</p>
<pre><code>Unable to find control with id
'ctl00_MainContentPlaceholder_MatrixSetControl_mec50_tb'
that is associated with the Label 'lb'.
</code></pre>
<p>Ok so a little background. I got this main-composite control that dynamically adds a number of 'elements' to its control collection. One of these elements happen to be this 'MatrixTextBox' which is the control consisting of a TextBox and a Label.</p>
<p>I hold the Label and TextBox as protected class variables and init them in CreateChildControls:</p>
<pre><code> ElementTextBox = new TextBox();
ElementTextBox.ID = "tb";
Controls.Add(ElementTextBox);
ElementLabel = new Label();
ElementLabel.ID = "lb";
Controls.Add(ElementLabel);
</code></pre>
<p>I tried setting the</p>
<pre><code>ElementLabel.AssociatedControlID = ElementTextBox.ClientID;
</code></pre>
<p>both right after adding the controls to the Controls collection and even in PreRender - both yield the same error. What am i doing wrong?</p>

<p>This is sort of a follow-up to <a href="https://stackoverflow.com/questions/223678">this question</a>.</p>
<p>If there are multiple blobs with the same contents, they are only stored once in the git repository because their SHA-1's will be identical. How would one go about finding all duplicate files for a given tree? </p>
<p>Would you have to walk the tree and look for duplicate hashes, or does git provide backlinks from each blob to all files in a tree that reference it?</p>

<p>What are the best practices to do transactions in C# .Net 2.0. What are the classes that should be used? What are the pitfalls to look out for etc. All that commit and rollback stuff. I'm just starting a project where I might need to do some transactions while inserting data into the DB. Any responses or links for even basic stuff about transactions are welcome. </p>

<p>I have a page which dynamically loads a section of content via AJAX. I'm concerned that this means the content will not be found by search engines.</p>
<p>To show you what I mean, the site is at <a href="http://www.gold09.net" rel="nofollow noreferrer">http://www.gold09.net</a> and the dynamic content is at <a href="http://www.gold09.net/speakers.php" rel="nofollow noreferrer">/speakers.php</a> - Normally no one would visit that second link, it's just loaded into the first page.</p>
<p>I know I can tell the crawlers to read the <code>speakers.php</code> by using a <code>sitemap.xml</code>, but then I'll get links to the speakers.php showing up in search results.</p>
<p>I guess the ultimate solution would be so that if someone requests <code>/speakers.php</code> it redirects them to the main page, whereas it lets crawlers read the data.</p>
<p>Any suggestions?</p>

<p>I ran into a problem while cleaning up some old code. This is the function:</p>
<pre><code>uint32_t ADT::get_connectivity_data( std::vector< std::vector<uint8_t> > &output )
{
output.resize(chunks.size());
for(chunk_vec_t::iterator it = chunks.begin(); it < chunks.end(); ++it)
{
uint32_t success = (*it)->get_connectivity_data(output[it-chunks.begin()]);
}
return TRUE;
}
</code></pre>
<p>What i am interested in doing is cleaning up the for loop to be a lambda expression but quickly got stuck on how exactly I would pass the correct argument to get_connectivity_data. get_connectivity_data takes a std::vector by reference and fills it with some data. output contains a std::vector for each "chunk".</p>
<p>Basically my conclusion for this was that it was substantially easier, cleaner and <em>shorter</em> to leave my code as-is.</p>
<p>EDIT:</p>
<p>So the closest answer to my question as I envisioned it would look was this:</p>
<pre><code> std::for_each( chunks.begin(), chunks.end(),
bind( &chunk_vec_t::value::type::get_connectivity_data,
_1,
output[ std::distance( _1, chunks.begn() ]
)
);
</code></pre>
<p>Yet that code does not compile, I made some modifications to the code to get it to compile but I ran into 2 issues:</p>
<ol>
<li>_ 1 is a smart ptr, and std::distance did not work on it, I think i needed to use &chunks[0] as the start</li>
<li>Since _ 1 is a smart pointer, I had to do: &chunk_vec_t::value_ type::ValueType::get_ connectivity_ data which caused a crash in the VC9 compiler...</li>
</ol>
<p>The answer regarding zip_ iterators looked good until i read more into it and discovered that for this particular use, the amount of extra code needed was substantial (binding this and that, etc).</p>
<p>EDIT2:</p>
<p>I found an acceptable solution that is both low on extraneous syntax and clear, which I've posted here and below.</p>
<pre><code>std::transform(chunks.begin(), chunks.end(), back_inserter(tmp), boost::bind(&ADTChunk::get_connectivity_data, _1) );
</code></pre>

<p>I had setup my clients & server for passwordless login.
Like passwordless login by copying RSA key of server to all client's /root/.ssh/id-rsa.pub. but this, I have done manually. I like to automate this process using shell script and providing password to the machines through script.
If this problem is solved then I also want to use rsync to automate push items to all servers.
Can any body help me in this regard.</p>
<p>Thank you</p>

<p>I have the following class:</p>
<pre><code>public abstract class AbstractParent {
static String method() {
return "OriginalOutput";
}
}
</code></pre>
<p>I want to mock this method. I decide to use <a href="http://jmockit.dev.java.net" rel="noreferrer">JMockit</a>. So I create a mock class:</p>
<pre><code>public class MockParent {
static String method() {
return "MOCK";
}
}
</code></pre>
<p>And my test code looks like this:</p>
<pre><code>public class RealParentTest {
@Before
public void setUp() throws Exception {
Mockit.redefineMethods( AbstractParent.class, MockParent.class );
}
@Test
public void testMethod() {
assertEquals(MockParent.method(),AbstractParent.method());
}
}
</code></pre>
<p>Unfortunately this test says that AbstractParent returns "OriginalOutput" instead of "MOCK". Any ideas why? Am I doing something wrong? I've tried declaring my mock class as abstract as well, to no avail.</p>
<p><strong>Edit</strong> Note that making the method public causes the test to run without a problem... this is weird because with JMockit you are supposed to be able to mock methods of any scope.</p>
<p><strong>Answer</strong> Only the mock method needs to be public, you can leave the original method as is.</p>

<p>I'm after some good tips for fluent interfaces in C#. I'm just learning about it myself but keen to hear what others think outside of the articles I am reading. In particular I'm after:</p>
<ol>
<li>when is fluent too much?</li>
<li>are there any fluent patterns?</li>
<li>what is in C# that makes fluent interfaces more fluent (e.g. extension methods)</li>
<li>is a complex fluent interface still a fluent one?</li>
<li>refactoring to arrive at a fluent interface or refactoring an existing fluent interface</li>
<li>any good examples out there that you have worked with or could recommend?</li>
</ol>
<p>If you could post one tip or thought, or whatever per post. I want to see how they get voted on, too.</p>
<p>Thank you in advance.</p>

<p>I have a database with <code>account numbers</code> and <code>card numbers</code>. I match these to a file to <code>update</code> any card numbers to the account number so that I am only working with account numbers.</p>
<p>I created a view linking the table to the account/card database to return the <code>Table ID</code> and the related account number, and now I need to update those records where the ID matches the Account Number.</p>
<p>This is the <code>Sales_Import</code> table, where the <code>account number</code> field needs to be updated:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>LeadID</th>
<th>AccountNumber</th>
</tr>
</thead>
<tbody>
<tr>
<td>147</td>
<td>5807811235</td>
</tr>
<tr>
<td>150</td>
<td>5807811326</td>
</tr>
<tr>
<td>185</td>
<td>7006100100007267039</td>
</tr>
</tbody>
</table>
</div>
<p>And this is the <code>RetrieveAccountNumber</code> table, where I need to update from:</p>
<div class="s-table-container">
<table class="s-table">
<thead>
<tr>
<th>LeadID</th>
<th>AccountNumber</th>
</tr>
</thead>
<tbody>
<tr>
<td>147</td>
<td>7006100100007266957</td>
</tr>
<tr>
<td>150</td>
<td>7006100100007267039</td>
</tr>
</tbody>
</table>
</div>
<p>I tried the below, but no luck so far:</p>
<pre><code>UPDATE [Sales_Lead].[dbo].[Sales_Import]
SET [AccountNumber] = (SELECT RetrieveAccountNumber.AccountNumber
FROM RetrieveAccountNumber
WHERE [Sales_Lead].[dbo].[Sales_Import]. LeadID =
RetrieveAccountNumber.LeadID)
</code></pre>
<p>It updates the card numbers to account numbers, but the account numbers get replaced by <code>NULL</code></p>

<p>I'm having trouble with a custom tag:-</p>
<p>org.apache.jasper.JasperException: /custom_tags.jsp(1,0) Unable to find setter method for attribute : firstname</p>
<p>This is my TagHandler class:</p>
<pre><code>package com.cg.tags;

}
public void setLastName(String lastname){

}
public int doStartTag() throws JspException {

out.println( "First name: "+firstname+ "Last name: "+lastname);

throw new JspException("IO problems");
}
return SKIP_BODY;
}
}
</code></pre>
<p>This is my TLD file:</p>
<pre><code>?xml version="1.0" encoding="UTF-8"?>

<p>And this is my JSP page:</p>
<pre><code><%@ taglib uri="/WEB-INF/nametagdesc.tld" prefix="cg" %>

</code></pre>
<p>I have checked that the code is recompiled and deployed correctly etc etc....</p>
<p>So, the question is , why can't it find the setter method???</p>

<p>I am trying to create a user interface using XAML. However, the file is quickly becoming very large and difficult to work with. What is the best way for splitting it across several files.</p>
<p>I would like to be able to set the content of an element such as a ComboBox to an element that is defined in a different xaml file (but in the same VS project).</p>
<p>thanks</p>

<p>I've noticed that plenty of opensource project doesn't use BITWISE flags anymore, even if it's fully supported by programming enviroment common for web ( php/Mysql).
It's that a "lost practise" for some effective problem, or is just that a lot of php programmers don't know how to handle this type of implementation?</p>
<p>Nothing too important, just very curious :)
thanks to you all</p>

<p>I'm trying to figure out how to pass arguments to an anonymous function in JavaScript.</p>
<p>Check out this sample code and I think you will see what I mean:</p>
<pre><code><input type="button" value="Click me" id="myButton" />
<script type="text/javascript">
var myButton = document.getElementById("myButton");
var myMessage = "it's working";
myButton.onclick = function(myMessage) { alert(myMessage); };
</script>
</code></pre>
<p>When clicking the button the message: <code>it's working</code> should appear. However the <code>myMessage</code> variable inside the anonymous function is null.</p>
<p>jQuery uses a lot of anonymous functions, what is the best way to pass that argument?</p>

<p>I have a large script file (nearly 300MB, and feasibly bigger in the future) that I am trying to run. It has been suggested in the comments of Gulzar's answer to my <a href="https://stackoverflow.com/questions/222442/sql-server-running-large-script-files">question about it</a> that I should change the script timeout to 0 (no timeout).</p>
<p>What is the best way to set this timeout from within the script? At the moment I have all of this at the top of the script file in the hopes that one of them does something:</p>
<pre><code>sp_configure 'remote login timeout', 600
go
sp_configure 'remote query timeout', 0
go
sp_configure 'query wait', 0
go
reconfigure with override
go
</code></pre>
<p>However, I'm still getting the same result and I can't tell if I'm succeeding in setting the timeout because the response from sqlcmd.exe is the world's least helpful error message:</p>
<blockquote>
<p>Sqlcmd: Error: Scripting error.</p>
</blockquote>

<p>I am using the ruby daemons gem to create a custom daemon for my rails project. The only problem is that when I try to start the daemons <code>ruby lib/daemons/test_ctl start</code> that it fails and will not start. The log file has this output.</p>
<pre><code># Logfile created on Wed Oct 22 16:14:23 +0000 2008 by /
*** below you find the most recent exception thrown, this will be likely (but not certainly) the exception that made the application exit abnormally \*\*\*
# MissingSourceFile: no such file to load -- utf8proc_native
*** below you find all exception objects found in memory, some of them may have been thrown in your application, others may just be in memory because they are standard exceptions ***
# NoMemoryError: failed to allocate memory>
# SystemStackError: stack level too deep>
# fatal: exception reentered>
# LoadError: no such file to load -- daemons>
# LoadError: no such file to load -- active_support>
# MissingSourceFile: no such file to load -- lib/string>
# MissingSourceFile: no such file to load -- utf8proc_native>
</code></pre>
<p>It even happens when I generate a daemon (from the rails plugin) and try to run it. Does anybody know how to fix this problem? </p>

<p>I'm wondering if there are any simple ways to get a list of all fixed-width (monospaced) fonts installed on a user's system in C#?</p>
<p>I'm using .net 3.5 so have access to the WPF System.Windows.Media namespace and LINQ to get font information, but I'm not sure what I'm looking for.</p>
<p>I want to be able to provide a filtered list of monospaced fonts and/or pick out monospaced fonts from a larger list of fonts (as seen in the VS options dialog).</p>

<p>I know it's simple to implement, but I want to reuse something that already exist.</p>
<p>Problem I want to solve is that I load configuration (from XML so I want to cache them) for different pages, roles, ... so the combination of inputs can grow quite much (but in 99% will not). To handle this 1%, I want to have some max number of items in cache...</p>
<p>Till know I have found org.apache.commons.collections.map.LRUMap in apache commons and it looks fine but want to check also something else. Any recommendations?</p>

<p>Is it possible to do the equivalent of the following in xslt:</p>
<pre><code>.//TagA[./TagB/[@AttrA='AttrAValue'] = 'TagBValue']
</code></pre>
<p>This is failing within Visual Studio 2008 with the following error:</p>
<pre><code>error: Unexpected token '[' in the expression.
.//TagA[./TagB/ -->[<-- @AttrA='AttrAValue'] = 'TagBValue']
</code></pre>
<p>Should this be working? Is this a problem in the MS implementation of XSLT, or is there a way I can get all TagA nodes that have a TagB node whose AttrA is equal to AttrAValue and whose TagB innerText is equal to TagBValue.</p>

<p>What is the best way to find out whether two number ranges intersect?</p>
<p>My number range is <strong>3023-7430</strong>, now I want to test which of the following number ranges intersect with it: <3000, 3000-6000, 6000-8000, 8000-10000, >10000. The answer should be <strong>3000-6000</strong> and <strong>6000-8000</strong>.</p>
<p>What's the nice, efficient mathematical way to do this in any programming language?</p>

<p>for example, I have the following xml document:</p>
<pre><code>def CAR_RECORDS = '''
<records>
<car name='HSV Maloo' make='Holden' year='2006'/>
<car name='P50' make='Peel' year='1962'/>
<car name='Royale' make='Bugatti' year='1931'/>
</records>
'''
</code></pre>
<p>and I want to move the car "Royale" up to first one, and insert a new car just after car"HSV Maloo", the result would be:</p>
<pre><code>'''
<records>
<car name='Royale' make='Bugatti' year='1931'/>
<car name='HSV Maloo' make='Holden' year='2006'/>
<car name='My New Car' make='Peel' year='1962'/>
<car name='P50' make='Peel' year='1962'/>
</records>
'''
</code></pre>
<p>How to do it with Groovy? comments are welcome.</p>

<p>Imagine you're creating a presentation that will be translated into a dozen different languages, including ones with non-latin characters (Chinese, for instance). The client's branding style guide dictates that certain fonts are acceptable for certain languages. The content itself is required to be externalized, so that the text can be replaced without ever opening a .fla, or re-saving a graphic.</p>
<p>So we're talking dynamic TextField s, populated from XML, with the font swapped out to accommodate the viewer's locale - what's the most painless way to dynamically load only the fonts required (regardless of the filesize), and apply them as necessary? I'm looking for solutions using <strong>Flash only, not Flex</strong>.</p>

<p>What ist most concise way to read the contents of a file or input stream in Java? Do I always have to create a buffer, read (at most) line by line and so on or is there a more concise way? I wish I could do just</p>
<pre><code>String content = new File("test.txt").readFully();

<p>What is the difference between <code>private</code> and <code>protected</code> members in C++ classes?</p>
<p>I understand from best practice conventions that variables and functions which are not called outside the class should be made <code>private</code>—but looking at my MFC project, MFC seems to favor <code>protected</code>.</p>
<p>What's the difference and which should I use?</p>

And now I want some variables, so I can use them as integer: <code>a=1, a=2, a=3, a=4</code></p>
<p>How can I do that?</p>

<p>Some of us still "live" in a programming environment where unit testing has not yet been embraced. To get started, the obvious first step would be to try to implement a decent framework for unit testing, and I guess xUnit is the "standard".</p>
<p>So what is a good starting point for implementing xUnit in a new programming language?</p>
<p>BTW, since people are asking: My target environment is Visual Dataflex.</p>

<p>When debugging in Internet Explorer, I first get an alert box with extremely limited if not useless information (sorry IE) and choose to debug it. After selecting yes, I get another option <em>every time</em> to choose between 'New instance of Microsoft script debugger' and 'New instance of Visual Studio'. I'm fed up with having to click the yes button again after having clicked it once already on the alert box.</p>
<p>Update: I found that you can disable the Microsoft script debugger from within its own options; just disabling the JIT debugger from Tools -> Options, and JIT. This stops it appearing on the menu but now I get the dialog box asking me which one to choose and it only displays the Visual Studio - WHY? If there's only one option and you've already asked me if I want to debug, why ask again?!?! Bleh.</p>
<p>Can you tell I'm getting sick of clicking, "yes" twice? Lol.</p>

<p>I am using a native library which returns an IntPtr to a memory location, which contains the value of an attribute. I know what the type of the attribute is and I have a method for marshalling a value (taking the IntPtr and the type of the attribute) from the memory pointed at by the pointer. This method either calls Marshal.ReadInt32, or reads a series of bytes and converts them to a double, or reads a string with Marshal.PtrToStringUni etc etc. I would like to write some unit tests for this method but am not sure how I go about creating the IntPtr to pass to the method. I'm using NUnit and cannot use a mocking framework.</p>

<p>I've been reading up on conditional-style expressions in ruby. However I came across one I couldn't quite understand to define the classic FizzBuzz problem. I understand the FizzBuzz problem and even wrote my own before finding the following quick solution utilising the ternary operator. If someone can explain to me how this chain works to satisfy the FizzBuzz problem it would be very much appreciated :)</p>
<pre><code>for i in 0...100
puts i%3==0 ? i%5==0 ? "FizzBuzz" : "Buzz" : i%5==0 ? "Fizz" : i
end
</code></pre>

<p>How do I get the KeyDown event to work in a Delphi (2007) MDI Applications Parent window, even if a Child window has focus?</p>
<p>I would like to implement a shortcut key (F1) that brings up a help screen in a MDI application, I have added the KeyDown procedure to the MDI Parent window and enabled KeyPreview in both the Parent and Child windows, but it does not work as expected.</p>
<p>If I put a break point in the Parents KeyDown code I can see it never executes, even it there are no child windows open. But if I add the same code to the child window it works fine.</p>
<p>Is there a way to get the parent window to receive the key presses, even if the child window has focus, as adding the code to 25+ forms seams a little wasteful?</p>

<p>I am making an web based appliaction in java (using jsp). When the appliaction is invoked login page will come, when the user enter the valid credientials, he will be taken to the index page. But the problem is, when the login is success, the index page is coming but it is opening behind the login page. (means login page appears on the top of the monitor, I want index page should appear on the top of the window.) Can anyone help me out in this...Please</p>
