<p>The windows installed on my machine has the locale <code>en_AU</code> and that's what JasperReports uses. I already tried changing the locale of all users, including the Administrator but it still uses <code>en_AU</code>.</p>
<p>How can I change that locale? Is it possible to change the <code>REPORT_LOCALE</code> parameter on my report?</p>

<p>I want to create a javascript badge that displays a list of links. We host the javascript on our domain. Other sites can put an empty div tag on their page and at the bottom a reference to our javascript that would render the content in the div tag. How do you implement something like this?</p>

<p>I'm busy with an asignment where i have to make a graphical interface for a simple program. But i'm strugling with the layout.</p>
<p>This is the idea:<br>
<img src="https://i.stack.imgur.com/a3Xk7.png" alt="Layout Example" title="Layout Example"></p>
<p>What is the easiest way to accomplish such a layout?</p>
<p>And what method do you use to make layouts in java. Just code it, or use an IDE like netbeans?</p>

<p>I am trying to build a dropdown list for a winform interop, and I am creating the dropdown in code. However, I have a problem getting the data to bind based on the DataTemplate I specify.</p>
<p>What am I missing?</p>
<pre><code>drpCreditCardNumberWpf = new ComboBox();
DataTemplate cardLayout = new DataTemplate {DataType = typeof (CreditCardPayment)};
StackPanel sp = new StackPanel
{
Orientation = System.Windows.Controls.Orientation.Vertical
};
TextBlock cardHolder = new TextBlock {ToolTip = "Card Holder Name"};
cardHolder.SetBinding(TextBlock.TextProperty, "BillToName");
sp.Children.Add(cardHolder);
TextBlock cardNumber = new TextBlock {ToolTip = "Credit Card Number"};
cardNumber.SetBinding(TextBlock.TextProperty, "SafeNumber");
sp.Children.Add(cardNumber);
TextBlock notes = new TextBlock {ToolTip = "Notes"};
notes.SetBinding(TextBlock.TextProperty, "Notes");
sp.Children.Add(notes);
cardLayout.Resources.Add(sp, null);
drpCreditCardNumberWpf.ItemTemplate = cardLayout;

<p>I have a range of random numbers. The range is actually determined by the user but it will be up to 1000 integers. They are placed in this:</p>
<pre><code>vector<int> n
</code></pre>
<p>and the values are inserted like this:</p>
<pre><code>srand(1);
for (i = 0; i < n; i++)
v[i] = rand() % n;
</code></pre>
<p>I'm creating a separate function to find all the non-prime values. Here is what I have now, but I know it's completely wrong as I get both prime and composite in the series.</p>
<pre><code>void sieve(vector<int> v, int n)
{
int i,j;
for(i = 2; i <= n; i++)
{
cout << i << " % ";
for(j = 0; j <= n; j++)
{
if(i % v[j] == 0)
cout << v[j] << endl;
}
}
}
</code></pre>
<p>This method typically worked when I just had a series of numbers from 0-1000, but it doesn't seem to be working now when I have numbers out of order and duplicates. Is there a better method to find non-prime numbers in a vector? I'm tempted to just create another vector, fill it with n numbers and just find the non-primes that way, but would that be inefficient?</p>
<p>Okay, since the range is from 0-1000 I am wondering if it's easier to just create vector with 0-n sorted, and then using a sieve to find the primes, is this getting any closer?</p>
<pre><code>void sieve(vector<int> v, BST<int> t, int n)
{
vector<int> v_nonPrime(n);
int i,j;
for(i = 2; i < n; i++)
v_nonPrime[i] = i;
for(i = 2; i < n; i++)
{
for(j = i + 1; j < n; j++)
{
if(v_nonPrime[i] % j == 0)
cout << v_nonPrime[i] << endl;
}
}
}
</code></pre>

<p>I have some thread-related questions, assuming the following code. Please ignore the possible inefficiency of the code, I'm only interested in the thread part.</p>
<pre><code>//code without thread use
public static int getNextPrime(int from) {
int nextPrime = from+1;
boolean superPrime = false;
while(!superPrime) {
boolean prime = true;
for(int i = 2;i < nextPrime;i++) {
if(nextPrime % i == 0) {
prime = false;
}
}
if(prime) {
superPrime = true;
} else {
nextPrime++;
}
}
return nextPrime;
}
public static void main(String[] args) {
int primeStart = 5;
ArrayList list = new ArrayList();
for(int i = 0;i < 10000;i++) {
list.add(primeStart);
primeStart = getNextPrime(primeStart);
}
}
</code></pre>
<p>If I'm running the code like this and it takes about 56 seconds. If, however, I have the following code (as an alternative):</p>
<pre><code>public class PrimeRunnable implements Runnable {
private int from;
private int lastPrime;
public PrimeRunnable(int from) {
this.from = from;
}
public boolean isPrime(int number) {
for(int i = 2;i < from;i++) {
if((number % i) == 0) {
return false;
}
}
lastPrime = number;
return true;
}
public int getLastPrime() {
return lastPrime;
}
public void run() {
while(!isPrime(++from))
;
}
}
public static void main(String[] args) {
int primeStart = 5;
ArrayList list = new ArrayList();
for(int i = 0;i < 10000;i++) {
PrimeRunnable pr = new PrimeRunnable(primeStart);
Thread t = new Thread(pr);
t.start();
t.join();
primeStart = pr.getLastPrime();
list.add(primeStart);
}
}
</code></pre>
<p>The whole operation takes about 7 seconds. I am almost certain that even though I only create one thread at a time, a thread doesn't always finish when another is created. Is that right? I am also curious: why is the operation ending so fast?</p>
<p>When I'm joining a thread, do other threads keep running in the background, or is the joined thread the only one that's running?</p>

<p>I have discovered through trial and error that the MATLAB engine function is not completely thread safe.</p>
<p>Does anyone know the rules?</p>
<p>Discovered through trial and error:</p>
<p>On Windows, the connection to MATLAB is via COM, so the COM Apartment threading rules apply. All calls must occur in the same thread, but multiple connections can occur in multiple threads as long as each connection is isolated.</p>
<p>From the answers below, it seems that this is not the case on UNIX, where calls can be made from multiple threads as long as the calls are made serially.</p>

<p>I know that this is a bad thing to do but I am in the unfortunate situation that this is really the only way I can achieve what I need (as I cannot modify this particular coworker's code).</p>
<p>Also, I know that LiteralControl allows you to have a control with arbitrary HTML in it, but unfortunately I need to have them converted to proper control.</p>
<p>Unfortunately, HTMLTable does not support the InnerHTML property. I need to preserve the HTML tree exactly as it is, so I cannot put it into a <code><div></code> tag.</p>
<p>Thanks.</p>

<p>We are deploying our ASP.NET 3.5 app to a production server for beta testing.</p>
<p>Each page is secured using SSL.</p>
<p>On our homepage (default.aspx) we have web services which populate flash objects.</p>
<p>I am getting an error:</p>
<p>The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'.</p>
<p>Also, when using firefox, receive the Windows Login pop up screen.</p>
<p>Does anyone have any clue what or why this is happening?</p>
<p>Much thanks!</p>

<p>I'm writing a script to remove some build artifacts older than 1 week. </p>
<p>The files have names in the form <em>artifact-1.1-200810391018.exe</em>.</p>
<p>How do I go about removing only the files that are greater than 1 week old, excluding the time in hours and minutes at the end of the date-time-stamp?</p>
<p>Currently it is removing all of the files in the directory.</p>
<pre><code>#!/bin/sh
NIGHTLY_LOCATIONS=( "/foo" "/bar" )
ARTIFACT_PREFIX="artifact-*-"
NUM_TO_KEEP=7
for home in $(seq 0 $((${#NIGHTLY_LOCATIONS[@]} - 1))); do
echo "Removing artifacts for" ${NIGHTLY_LOCATIONS[$location]}
for file in `find ${NIGHTLY_LOCATIONS[$location]} -name "$ARTIFACT_PREFIX*"`; do
keep=true
for day in $(seq 0 $((${NUM_TO_KEEP} - 1))); do
date=`date --date="$day days ago" +%Y%m%d`
echo $(basename $file ".exe") " = " $ARTIFACT_PREFIX$date
if [ "$(basename $file ".exe")" != "$ARTIFACT_PREFIX$date" ]; then
keep=false
fi
done
if [ !$keep ]; then
echo "Removing file"
rm -f $file
fi
done done
</code></pre>

<p>I am writing a custom session handler in PHP and trying to make the methods defined in session_set_save_handler private.</p>
<pre><code>session_set_save_handler(
array('Session','open'),
array('Session','close'),
array('Session','read'),
array('Session','write'),
array('Session','destroy'),
array('Session','gc')
);
</code></pre>
<p>For example I can set the open function to be private without any errors, but when I make the write method private it barks at me.</p>
<blockquote>
<p>Fatal error: Call to private method
Session::write() from context '' in
Unknown on line 0</p>
</blockquote>
<p>I was just wondering if this was a bug or there is a way around this. Barring that I can certainly just make it public, but I'd rather not. There was a post from last year on php.net eluding to a similar thing, but just want to know if anyone had any ideas. Does it really matter? I am using PHP 5.2.0 on my development box, but could certainly upgrade. </p>

<p>I want to run a background task that reads input from a TextReader and processes it a line at a time. I want the background task to block until the user types some text into a field and clicks the submit button. Is there some flavour of TextReader that will block until text is available and lets you somehow add more text to the underlying source?</p>
<p>I thought that a StreamReader and StreamWriter pointing to the same MemoryStream might work, but it doesn't seem to. The StreamReader sees that the MemoryStream is empty at the start, and never checks again.</p>
<p>I realize that it would be easier to write a ProcessLine() method and call it whenever the user clicks the submit button. However, I'm trying to design a plug-in architecture, and I'd like the plug ins to look like old-fashioned console apps with an input stream and an output stream. I want the plug in's input stream to just block until the user clicks the submit button with some input text.</p>

<p>I am working on a windows service that polls for a connection to a network enabled devices every 15 seconds. If the service is not able to connect to a device, it throws an exception and tries again in 15 seconds. All of this works great.</p>
<p>But, lets say one of the devices is down for a day or more. I am filling up my exception log with the same exception every 15 seconds. Is there a standard way to prevent an exception from being written to the event log if the exception being thrown hasn't changed in the last x number of hours?</p>

<p><strong>Question</strong></p>
<p>I have an application written in Java. It is designed to run on a Linux box standalone. I am trying to spawn a new <em>firefox</em> window. However, <em>firefox</em> never opens. It always has a shell exit code of 1. I can run this same code with <em>gnome-terminal</em> and it opens fine.</p>
<p><strong>Background</strong></p>
<p>So, here is its initialization process:</p>
<ol>
<li>Start X "Xorg :1 -br -terminate -dpms -quiet vt7"</li>
<li>Start Window Manager "metacity --display=:1 --replace"</li>
<li>Configure resources "xrdb -merge /etc/X11/Xresources"</li>
<li>Become a daemon and disconnect from controlling terminal</li>
</ol>
<p>Once the program is up an running, there is a button the user can click that should spawn a firefox window. Here is my code to do that. Remember X is running on display :1.</p>
<p><strong>Code</strong></p>
<pre><code>
public boolean openBrowser()
{
try {
Process oProc = Runtime.getRuntime().exec( "/usr/bin/firefox --display=:1" );
int bExit = oProc.waitFor(); // This is always 1 for some reason
return true;
} catch ( Exception e ) {
oLogger.log( Level.WARNING, "Open Browser", e );
return false;
}
}
</code></pre>

<p>How can you find out the number of active users when you're using a StateServer? Also is it possible to query the StateServer and retrieve the contents in the Session State? </p>
<p>I know that this is all possible if you use SqlServer for a backing store, but I want them to be in memory.</p>

<p>I have a listbox, and I have the following ItemTemplate for it:</p>
<pre><code><DataTemplate x:Key="ScenarioItemTemplate">
<Border Margin="5,0,5,0"
Background="#FF3C3B3B"
BorderBrush="#FF797878"
BorderThickness="2"
CornerRadius="5">
<DockPanel>
<DockPanel DockPanel.Dock="Top"
Margin="0,2,0,0">
<Button HorizontalAlignment="Left"
DockPanel.Dock="Left"
FontWeight="Heavy"
Foreground="White" />
<Label Content="{Binding Path=Name}"
DockPanel.Dock="Left"
FontWeight="Heavy"
Foreground="white" />
<Label HorizontalAlignment="Right"
Background="#FF3C3B3B"
Content="X"
DockPanel.Dock="Left"
FontWeight="Heavy"
Foreground="White" />
</DockPanel>
<ContentControl Name="designerContent"
Visibility="Collapsed"
MinHeight="100"
Margin="2,0,2,2"
Content="{Binding Path=DesignerInstance}"
Background="#FF999898">
</ContentControl>
</DockPanel>
</Border>
</DataTemplate>
</code></pre>
<p>As you can see the ContentControl has Visibility set to collapsed.</p>
<p>I need to define a trigger that causes the Visibility to be set to "Visible"</p>
<p>when the ListItem is selected, but I can't figure it out.</p>
<p>Any ideas? </p>
<p>UPDATE: Of course I could simply duplicate the DataTemplate and add triggers
to the ListBox in question to use either one or the other, but I want to prevent duplicating this code.</p>

<p>In the debugger, addr has all the current values from the db table, and I can verify that AddressLine1 is changed just before I call db.SubmitChanges()... SQL Profiler shows only a "reset connection" when the SubmitChanges line executes. Anyone got a clue why this isn't working? THANKS!</p>

<p>I have a Spring MVC web app which uses Spring Security. I want to know the username of the currently logged in user. I'm using the code snippet given below . Is this the accepted way? </p>
<p>I don't like having a call to a static method inside this controller - that defeats the whole purpose of Spring, IMHO. Is there a way to configure the app to have the current SecurityContext, or current Authentication, injected instead? </p>
<pre><code> @RequestMapping(method = RequestMethod.GET)
public ModelAndView showResults(final HttpServletRequest request...) {
final String currentUser = SecurityContextHolder.getContext().getAuthentication().getName();
...

<p>I'm having a problem, creating a fixed-size overall panel for a touchscreen GUI application that has to take up the entire screen. In a nutshell, the touchscreen is 800 x 600 pixels, and therefore I want the main GUI panel to be that size.</p>
<p>When I start a new GUI project in NetBeans, I set the properties of the main panel for min/max/preferred size to 800 x 600, and the panel within the 'Design' view changes size. However, when I launch the app, it is resized to the original default size.</p>
<p>Adding this code after initComponents() does not help:</p>
<pre><code>this.mainPanel.setSize(new Dimension(800,600));
this.mainPanel.setMaximumSize(new Dimension(800,600));
this.mainPanel.setMinimumSize(new Dimension(800,600));
this.mainPanel.repaint();
</code></pre>
<p>I've peeked into all of the resource files and cannot seem to find values that would override these (which seems somewhat impossible anyway, given that I'm setting them after initComponents() does its work). I'm using the FreeDesign layout, because I wanted complete control over where I put things.</p>
<p>I suspect the layout manager is resizing things based upon how many widgets I have on the screen, because different prototyped screens come in at differing sizes. </p>
<p>Help is appreciated!</p>

<p>Anyone have a good resource or provide a sample of a natural order sort in C# for an <code>FileInfo</code> array? I am implementing the <code>IComparer</code> interface in my sorts.</p>

<p>I have a private const int defined in a C# class. I want compilation to fail with an error if the value of this int mod 3 != 0. How can I accomplish this?</p>

<p>I'm wondering if it is possible to add methods in main program to an existing class defined in header file.
For example:
There is <code>class CFun</code> defined in file <code>CFun.hpp</code>, but in our <code>party.cpp</code> we want to add a method <code>void hello() {cout << "hello" << endl;};</code>without editing <code>CFun.hpp</code></p>
<p>Obviously (unfortunately) construction:</p>
<pre><code>#include "CFun.hpp"
class CFun
{
public:
void hello() {cout << "hello" << endl;};
};
</code></pre>
<p>doesn't work returning an error <code>Multiple declaration for 'CFun'</code></p>
<p>Is it possible to make it work without class inheritance?</p>

<p>Objective: take a UIImage, crop out a square in the middle, change size of square to 320x320 pixels, slice up the image into 16 80x80 images, save the 16 images in an array.</p>
<p>Here's my code:</p>
<pre><code>CGImageRef originalImage, resizedImage, finalImage, tmp;
float imgWidth, imgHeight, diff;
UIImage *squareImage, *playImage;
NSMutableArray *tileImgArray;
int r, c;
originalImage = [image CGImage];
imgWidth = image.size.width;
imgHeight = image.size.height;
diff = fabs(imgWidth - imgHeight);
if(imgWidth > imgHeight){
resizedImage = CGImageCreateWithImageInRect(originalImage, CGRectMake(floor(diff/2), 0, imgHeight, imgHeight));
}else{
resizedImage = CGImageCreateWithImageInRect(originalImage, CGRectMake(0, floor(diff/2), imgWidth, imgWidth));
}
CGImageRelease(originalImage);
squareImage = [UIImage imageWithCGImage:resizedImage];
if(squareImage.size.width != squareImage.size.height){
NSLog(@"image cutout error!");
//*code to return to main menu of app, irrelevant here
}else{
float newDim = squareImage.size.width;
if(newDim != 320.0){
CGSize finalSize = CGSizeMake(320.0, 320.0);
UIGraphicsBeginImageContext(finalSize);
[squareImage drawInRect:CGRectMake(0, 0, finalSize.width, finalSize.height)];
playImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
}else{
playImage = squareImage;
}
}
finalImage = [playImage CGImage];
tileImgArray = [NSMutableArray arrayWithCapacity:0];
for(int i = 0; i < 16; i++){
r = i/4;
c = i%4;
//*
tmp = CGImageCreateWithImageInRect(finalImage, CGRectMake(c*tileSize, r*tileSize, tileSize, tileSize));
[tileImgArray addObject:[UIImage imageWithCGImage:tmp]];
}
</code></pre>
<p>The code works correctly when the original (the variable image) has its smaller dimension either bigger or smaller than 320 pixels. When it's exactly 320, the resulting 80x80 images are almost entirely black, some with a few pixels at the edges that may (I can't really tell) be from the original image.</p>
<p>I tested by displaying the full image both directly:</p>
<pre><code>[UIImage imageWithCGImage:finalImage];
</code></pre>
<p>And indirectly:</p>
<pre><code>[UIImage imageWithCGImage:CGImageCreateWithImageInRect(finalImage, CGRectMake(0, 0, 320, 320))];
</code></pre>
<p>In both cases, the display worked. The problems only arise when I attempt to slice out some part of the image.</p>

<p>I've been trying to code a Perl script to substitute some text on all source files of my project. I'm in need of something like:</p>
<pre><code>perl -p -i.bak -e "s/thisgoesout/thisgoesin/gi" *.{cs,aspx,ascx}
</code></pre>
<p>But that parses <strong>all</strong> the files of a directory <strong>recursively</strong>.</p>
<p>I just started a script:</p>
<pre><code>use File::Find::Rule;
use strict;
my @files = (File::Find::Rule->file()->name('*.cs','*.aspx','*.ascx')->in('.'));
foreach my $f (@files){
if ($f =~ s/thisgoesout/thisgoesin/gi) {
# In-place file editing, or something like that
}
}
</code></pre>
<p>But now I'm stuck. Is there a simple way to edit all files in place using Perl?</p>
<p>Please note that I don't need to keep a copy of every modified file; I'm have 'em all subversioned =)</p>
<p><strong>Update</strong>: I tried this on <a href="http://en.wikipedia.org/wiki/Cygwin" rel="nofollow noreferrer">Cygwin</a>,</p>
<pre><code>perl -p -i.bak -e "s/thisgoesout/thisgoesin/gi" {*,*/*,*/*/*}.{cs,aspx,ascx
</code></pre>
<p>But it looks like my arguments list exploded to the maximum size allowed. In fact, I'm getting very strange errors on Cygwin...</p>

<p>I want to do a select in MySql that combines several columns... something like this pseudocode:</p>
<pre><code>SELECT payment1_paid AND payment2_paid AS paid_in_full
FROM denormalized_payments
WHERE payment1_type = 'check';
</code></pre>
<p><strong>Edit</strong>: payment1_paid and payment2_paid are booleans.</p>
<p>I can't use any other language for this particular problem than MySql.</p>
<p>Thanks for any help!</p>
<p><strong>Edit</strong>: Sorry to everybody who gave me suggestions for summing and concatenating, but I've voted those early answers up because they're useful anyway. And <strong>thanks</strong> to everybody for your incredibly quick answers!</p>

<p>Rather not reinvent the wheel if it's already working and debugged.</p>
<p>Cheers,

<p>EDIT: Server-side ASP VBScript... I have already seen many javascript client side libraries.</p>

<p>I just came onto a project with a pretty huge code base. </p>
<p>I'm mostly dealing with C++ and a lot of the code they write uses double negation for their boolean logic. </p>
<pre><code> if (!!variable && (!!api.lookup("some-string"))) {
do_some_stuff();
}
</code></pre>
<p>I know these guys are intelligent programmers, it's obvious they aren't doing this by accident. </p>
<p>I'm no seasoned C++ expert, my only guess at why they are doing this is that they want to make absolutely positive that the value being evaluated is the actual boolean representation. So they negate it, then negate that again to get it back to its actual boolean value. </p>
<p>Is this correct, or am I missing something?</p>

<p>We are a group of students doing our Master degree in field of computer science.</p>
<p>This semester we should do a Software engineering project according to the following bottom explanation.</p>
<p>we should exactly act and report as a real Software engineering Team.</p>
<p>I have been chosen as a project manager of this group, I am good in writing java codes but I don't have the experience of doing the project manager task, any way I have to do my best to do this project with my group members as good as possible.</p>
<p>The problem is this that I need to deal with different levels of knowledge but all the members should participate in implementation part.</p>
<p>I will be pleased if some one guide me how to do this project and how to manage this group, and where to start? how to encourage the members, and how to do my plans in practice?</p>
<p>please have a look to the explanation and help me what technology do I need to chose for this project?</p>
<h2>Project Explanation</h2>
<p>projects should be implemented as so called web applications. Because of the MVC requirements this is more than a server-client architecture – we call this (at least) a three-tier architecture.</p>
<p>The view should be created dynamic on clients' request. Therefor the content has to be computed by the server (server side). Inside of the view there should not exist any type of source code (like “scriplets”, Java Code, etc.) besides the markup language.</p>
<p>This should ensure that the view can be created by web designers where the content is in the responsibility of programmers.</p>
<p>Vice versa the source code should not contain any markup languages (like HTML).</p>
<p>To store information (make persistent) the system should use a database. But there should not exist database specific queries inside of the source code – because then the sources are very dependent of the usage of exactly this database. System should work with an object relational mapper to map the stored information from database on special type of objects (beans).</p>
<p>All configuration like database, entities, configuration, initialization should be realized using XML files (or similar ways like e.g, annotations), so that changes don't require recompilation of the system's sources.</p>
<p>Technologies available (suggestions):</p>
<pre><code> J2EE:
JSP, Servlets, JSP EL,
JSTL, JSF, Facelets,
Custom JSF Components, Custom Facelets TagLibs,
JUnit (unit testing)
Persistence:
Hibernate, JDO
IDE:
Eclipse, NetBeans
Servlet Container:
Apache Tomcat
</code></pre>

<p>I need to have a single instance application (as per this <a href="https://stackoverflow.com/questions/19147/what-is-the-correct-way-to-create-a-single-instance-application#19326">answer</a>), but it needs to be deployed via click once.</p>
<p>The problem is that I require that click once doesn't automatically detect an update an attempt to load a newer version while the application is running. If it is running, then I need the other instance to be made active. Usually, when selecting a Click Once link, the very first thing it does is attempt to find an update. I want to intercept this and check for an already running instance <strong>prior</strong> to launching the normal update process.</p>
<p>Does anyone know how this is possible within a Click Once deployment scenario?</p>

<p>This is the sequel to <a href="https://stackoverflow.com/questions/248683/how-can-i-do-boolean-logic-on-two-columns-in-mysql">this question</a>.</p>
<p>I would like to combine three columns into one on a MySql select. The first two columns are boolean and the third is a string, which is sometimes null. This causes strange results:</p>
<pre><code>Select *, (payment1_paid && ((payment2_paid || payment2_type ="none"))) as paid_in_full from payments
</code></pre>
<p><strong>Note:</strong> <code>payment1_paid</code> is boolean, <code>payment2_paid</code> is boolean, <code>payment2_type</code> is varchar.</p>
<p><strong>Note:</strong> Please ignore how ridiculous the structure of this table is. Behind every piece of bad code there is a long explanation :)</p>
<p><strong>Edit:</strong> Null is not interesting to me for the varchar value. I only want to know if it's really "none."</p>
<p>Thanks in advance for your help!</p>

<p>Back in the earlier days of the internet I remember that in certain browsers, every time you downloaded an image or a file, the URL of where that file was downloaded from would be written into that file's properties (I guess the summary tab?). I think Netscape v2 did this if I remember correctly.</p>
<p>I really miss that kind of functionality as every once in a while I'll run into a neat little program stored somewhere in the depths of my hard drive and wonder where I got it from originally.</p>
<p>I googled around but I'm not quite sure what terms to use to describe what I'm looking for. So I'm wondering if anyone knows of a Firefox plug-in or something similar that would do this?</p>

<p>I'm not much of a Visual Basic person, but I am tasked with maintaining an old VB6 app. Whenever I check out a file, the editor will replace a bunch of the uppercase variable names with lowercase automatically. How can I make this stop!? I don't want to have to change them all back, and it's a pain to have these changes show up in SourceSafe "Differences" when I'm trying to locate the REAL differences.</p>
<p>It is changing it automatically in the definition, too:
<code>Dim C as Control</code> becomes <code>Dim c as Control</code>. <code>Dim X&</code> becomes <code>Dim x&</code>. But it doesn't do it all the time; for example, three lines down from <code>Dim x&</code>, there's a <code>Dim Y&</code>, uppercase, which it did not change. Why's it do this to me?</p>

<p>Hopefully I can do the problem justice, because it was too difficult to summarise it in the title! (suggestions are welcome in the comments)</p>
<p>Right, so here's my table:</p>
<pre><code>Tasks
task_id (number)
job_id (number)
to_do_by_date (date)
task_name (varchar / text)
status (number)
completed_date (date)
</code></pre>
<p>for arguments sake let's make the values of status:</p>
<pre><code>1 = New
2 = InProgress
3 = Done
</code></pre>
<p>and what I'm having trouble trying to do is create a query that pulls back all of the tasks:</p>
<ul>
<li>where any of the tasks for a <code>job_id</code> have a <code>status</code> <> Done
<ul>
<li>except where all tasks for a <code>job_id</code> are are done, but one or more tasks have a <code>completed_date</code> of today</li>
</ul></li>
<li>ordered by the <code>to_be_done_by</code> date, but grouping all of the job_id tasks together
<ul>
<li>so the <code>job_id</code> with the next `to_do_by_date' task is shown first</li>
</ul></li>
</ul>
<p>some information about the data:</p>
<ul>
<li>a <code>job_id</code> can have an arbitrary number of tasks</li>
</ul>
<p><br />
<strong>Here's an example of the output I'm trying to get:</strong></p>
<pre><code>task_id job_id to_do_by_date task_name status completed_date
1 1 yesterday - 3 yesterday
2 1 today - 3 today
3 2 now - 3 today
4 2 2 hours time - 2 {null}
5 2 4 hours time - 2 {null}
6 2 tomorrow - 1 {null}
7 3 3 hours time - 2 {null}
8 3 tomorrow - 1 {null}
9 3 tomorrow - 1 {null}
</code></pre>
<p><br />
I'm using Oracle 10g, so answers for Oracle or ANSI SQL, or a hint for how to approach this would be ideal, and I can create Views or wrap this in a Stored Procedure to offload logic from the application if your solution calls for it.</p>
<p><br />
here's a sql script that will create the example test data shown above:</p>
<pre><code>create table tasks (task_id number, job_id number, to_do_by_date date, task_name varchar2(50), status number, completed_date date);
insert into tasks values (0,0,sysdate -2, 'Job 0, Task 1 - dont return!', 3, sysdate -2);
insert into tasks values (1,1,sysdate -1, 'Job 1, Task 1', 3, sysdate -1);
insert into tasks values (2,1,sysdate -2/24, 'Job 1, Task 2', 3, sysdate -2/24);
insert into tasks values (3,2,sysdate, 'Job 2, Task 1', 3, sysdate);
insert into tasks values (4,2,sysdate +2/24, 'Job 2, Task 2', 2, null);
insert into tasks values (5,2,sysdate +4/24, 'Job 2, Task 3', 2, null);
insert into tasks values (6,2,sysdate +1, 'Job 2, Task 4', 1, null);
insert into tasks values (7,3,sysdate +3/24, 'Job 3, Task 1', 2, null);
insert into tasks values (8,3,sysdate +1, 'Job 3, Task 2', 1, null);
insert into tasks values (9,3,sysdate +1, 'Job 3, Task 3', 1, null);
commit;
</code></pre>
<p><br />
Many, many thanks for your help :o)</p>

<p>I am trying to to walk though the tree of PdfItem objects in an existing PDF document using PDFSharp in c#. </p>
<p>I want to create a hierarchy of all the objects as I go along -- similar to what the "PDF Explorer" example does -- but I want it to be a tree instead of a flat list of all the objects.</p>
<p>The root node is document.Internals.Catalog. And I want to to walk down through all the document.Internals.Catalog.Elements until I have visited every element.</p>
<p>One of the problems I run into is that there are circular references in the tree and I can't figure out how to detect them.</p>
<p>Any code samples out there?</p>

<p>I currently use Notepad++ for most of my development. I have been checking out other, more full-featured options and would like to switch (I'm in particular a fan of Aptana so far) but there is one thing about Notepad++ that I really like and I haven't been able to get so far. </p>
<p>My current workflow is something like this: <a href="http://evanalyze.com/images/workflow" rel="nofollow noreferrer">Workflow</a> (I tried to embed this image and it showed up in previews but not in the post, sorry)
<a href="http://evanalyze.com/images/workflow.jpg" rel="nofollow noreferrer">Workflow http://evanalyze.com/images/workflow.jpg</a></p>
<p>The process is this:</p>
<ol>
<li>Download file from web server</li>
<li>Make edits in NP++</li>
<li>Save (this automatically saves a local copy in my default directory, which is also the folder I have setup using Subversion with Tourtise SVN)</li>
<li>When I want to commit a change to SVN, go through the local folder that has an up to date copy</li>
</ol>
<p>What I can't figure out how to do with Aptana is automatically store a local copy of a file I download from my server, edit and save back to the server. Is there some way to do this? If so, that would solve my problem immediately.</p>
<p>Other options would be a suggestion for a better way to manage the relationship between my server, my editor and my SVN repository. I know Aptana can access my SVN repository too. Is there an easy way to commit changes from within Aptana when I want to (which means I could take Tourtise out of the equation I guess)?</p>
<p>Any suggestions appreciated. Thanks.</p>

<p>So I'm reading The Art & Science of Javascript, which is a good book, and it has a good section on JSONP. I've been reading all I can about it today, and even looking through every question here on StackOverflow. JSONP is a great idea, but it only seems to resolve the "Same Origin Problem" for <i>getting</i> data, but doesn't address it for <i>changing</i> data. </p>
<p>Did I just miss all the blogs that talked about this, or is JSONP <strong>not</strong> the solution I was hoping for?</p>

<p>As far as I know there's no way to hint the c# compiler to inline a particular function and I guess it's like that by design.</p>
<p>I also think that not letting the programmer to specify what to inline and what not is generally a good idea, as it would imply that you think you're smarter than the JIT compiler (my respects to those who actually are), but, what if I wanted to specify that a critical portion of code needs to be extremely fast at any cost, no matter how to achieve it on the target machine? As of yet you can't do such a thing and I wonder if both the c# language and the JIT will ever support this feature.</p>
<p>In my case, I know what the target machine is, and I know that function inlining will help improve the performance. This leaves me thinking that the only way to enforce function inlining is getting to know under what circumstances the JIT will do it but I don't think that's a good idea either,</p>
<p>Any light on the subject would be much appreciated.</p>
<p>Thanks.</p>

<p>Recently I wrote a function to generate certain sequences with nontrivial constraints. The problem came with a natural recursive solution. Now it happens that, even for relatively small input, the sequences are several thousands, thus I would prefer to use my algorithm as a generator instead of using it to fill a list with all the sequences.</p>
<p>Here is an example. Suppose we want to compute all the permutations of a string with a recursive function. The following naive algorithm takes an extra argument 'storage' and appends a permutation to it whenever it finds one:</p>
<pre><code>def getPermutations(string, storage, prefix=""):
if len(string) == 1:
storage.append(prefix + string) # <-----
else:
for i in range(len(string)):
getPermutations(string[:i]+string[i+1:], storage, prefix+string[i])
storage = []
getPermutations("abcd", storage)
for permutation in storage: print permutation
</code></pre>
<p>(Please don't care about inefficiency, this is only an example.)</p>
<p>Now I want to turn my function into a generator, i.e. to yield a permutation instead of appending it to the storage list:</p>
<pre><code>def getPermutations(string, prefix=""):
if len(string) == 1:
yield prefix + string # <-----
else:
for i in range(len(string)):
getPermutations(string[:i]+string[i+1:], prefix+string[i])
for permutation in getPermutations("abcd"):
print permutation
</code></pre>
<p>This code does <em>not</em> work (the function behaves like an empty generator).</p>
<p>Am I missing something?
Is there a way to turn the above recursive algorithm into a generator <em>without replacing it with an iterative one</em>?</p>

<p>I have a MySQL database table with a couple thousand rows. The table is setup like so:</p>
<p><code>id | text</code></p>
<p>The <code>id</code> column is an auto-incrementing integer, and the <code>text</code> column is a 200-character varchar.</p>
<p>Say I have the following rows:</p>
<p><code>3 | I think I'll have duck tonight</code></p>
<p><code>4 | Maybe the chicken will be alright</code></p>
<p><code>5 | I have a pet duck now, awesome!</code></p>
<p><code>6 | I love duck</code></p>
<p>Then the list I'm wanting to generate might be something like:</p>
<ul>
<li>3 occurrences of 'duck'</li>
<li>3 occurrences of 'I'</li>
<li>2 occurrences of 'have'</li>
<li>1 occurrences of 'chicken'</li>
<li>.etc .etc</li>
</ul>
<p>Plus, I'll probably want to maintain a list of substrings to ignore from the list, like 'I', 'will' and 'have. It's important to note that I do not know what people will post.</p>
<p>I do not have a list of words that I want to monitor, I just want to find the most common substrings. I'll then filter out any erroneous substrings that are not interesting from the list manually by editing the query.</p>
<p>Can anyone suggest the best way to do this? Thanks everyone!</p>

<p>I have a single HW interface I want to use from two applications (processes) on the same workstation. The HW requires a single initialization call then either app uses the same function (in the same library) to do many transactions with the HW. </p>
<p>So each app should act like this:</p>
<pre><code>main()
// I don't know if another app already init'ed the HW
ret = hw_init_lock(non-blocking)
if ret = OK
// no one else has done this, I have to
init_hw()
else
//someone else has already init'ed the HW, I gotta make sure it stays that way
//as long as I'm alive
increment_hw_init_ref_counter()
hw_trans_lock(blocking)
hw_trans()
hw_trans_unlock()
....
//exit app, uninit hw if we are last out
ret = decrement_hw_init_ref_counter()
if ret == 0
uninit_hw()
exit(0)
</code></pre>
<p>What is the mechanism I can use in the lock and reference count calls that is shared between two applications? I'm thinking named pipes i.e. mkfifo(). </p>

<p>Solution<br/>
-- WorkflowProject<br/>
-- Workflow1<br/>
-- Workflow2<br/>
-- WebProject (WAP)<br/>
-- App_Data<br/>
-- MyDatabase.vdb3<br/>
-- MyWebService.asmx<br/>
-- Web.Config<br/></p>
<p>Ok, so.. that's the basic "outline" of the project.
The database, is stored in the website, and is a VistaDB database (this could also be an MSAccess or SQLite Database). In the website, I could code against the database. I might have |DataDirectory| in my connection string.</p>
<p>The WORKFLOW project is separate from the Website. The MyWebService.asmx is a "stub" for calling the Workflow based web service. </p>
<p><strong><em>How</strong> do I open the database in the website <strong>App_Data</strong> directory ? Right now, I have the value hardcoded (i.e., @"E:\datadirectory\database.vdb3"), but this is not preferred and would only work on my development machine.</em></p>
<p>I can't even pass in the location of the database, since the webservice (the .asmx file) is only 1 line, and is stub code for getting the caller into the workflow. I'm really at a loss as how to proceed.</p>
<p>Solution ? Best practices ? Links ?</p>

<p>I am looking to parse a URL to obtain a collection of the querystring parameters in Java. To be clear, I need to parse a given URL(or string value of a URL object), not the URL from a servlet request. </p>
<p>It looks as if the <code>javax.servlet.http.HttpUtils.parseQueryString</code> method would be the obvious choice, but it has been deprecated.</p>
<p>Is there an alternative method that I am missing, or has it just been deprecated without an equivalent replacement/enhanced function?</p>

<p>We have a character LCD (www.cloverlcd.com/pdf/S6A0069.pdf) that we got to work in 8 bit mode. However, now we are trying to get it to work in 4 bit mode but it doesn't seem to be displaying anything. I think the function set instruction isn't been written. Can somebody please check if I am approaching this the right way? I'll post my 8 bit code (which is working) and my 4 bit code (which I'm trying to get to work)</p>
<pre>
//8 bit working
COMPortC(0x3C); //function set
Delay1KTCYx(10);
COMPortC(0x0F); //Turn on display and configure cursor settings
Delay1KTCYx(10);
COMPortC(0x01); //clear display
Delay1KTCYx(10);
COMPortC(0x06); //increment mode and increment direction (entry mode set)
Delay1KTCYx(10);
COMPortC(0x02); //Return Home
//4 bit
COMPortC(0x20); //function set
Delay1KTCYx(10);
COMPortC(0x20); //function set
Delay1KTCYx(10);
COMPortC(0x80); //function set
Delay1KTCYx(10);
COMPortC(0x00); //Turn on display and configure cursor settings
Delay1KTCYx(10);
COMPortC(0xF0); //Turn on display and configure cursor settings

<p>Imagine that you are handed a new book everyday from an author.
The book is a work in progress.
He does not tell you what he has changed or added.</p>
<p>Your job is to identify the changes and additions, and pass ONLY these along to the publisher (who does not have time to read the entire book everyday)</p>
<p>For the purposes of this problem, the book is comprised of 1m lines of ascii text and growing (actually a MySQL backup file).</p>
<p>My current idea is to make a secure hash (SHA256 for example) of each line (1k Chars) and store it on HD. Since the hash is only 32bytes the file is only 32MB.</p>
<p>Then when we get the next file tomorrow, we go through it line by line, creating a new hash for each line and comparing it to the hash from the previous day.</p>
<p>When the process is finished we overwrite the hash file ready for the next day.</p>
<p>The comparison uses a binary search method of string compare ( > < operands)
This returns a result in an average of four iterations.</p>
<p>I have not coded a btree index solution yet, but how would you tackle this?</p>

<p>I am just looking at the using statement, I have always known what it does but until now not tried using it, I have come up with the below code:</p>
<pre><code> using (SqlCommand cmd =
new SqlCommand(reportDataSource,
new SqlConnection(Settings.Default.qlsdat_extensionsConnectionString)))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@Year", SqlDbType.Char, 4).Value = year;
cmd.Parameters.Add("@startDate", SqlDbType.DateTime).Value = start;
cmd.Parameters.Add("@endDate", SqlDbType.DateTime).Value = end;
cmd.Connection.Open();
DataSet dset = new DataSet();
new SqlDataAdapter(cmd).Fill(dset);
this.gridDataSource.DataSource = dset.Tables[0];
}
</code></pre>
<p>This seems to work but is there any point in this since as far as I can tell I would still need to enclose this in a try catch block to catch unforseen errors e.g. sql server down. Am I missing something?</p>
<p>As far as I can currently see it just stops me closing and disposing of cmd but there will be more lines of code due to the try catch still being needed.</p>

<p>I have databound a listbox to a simple custom object collection. Next, I added a button to remove the selected item from the object collection. The problem is that when certain items are removed and the listbox is showing the vertical scroll bar, the scrollbar appears to reset to a new position, although what I really think is happening is that the control is repainting.</p>
<p>The folowing code sample demonstrates the problem. Add this code to a form, making sure that the vertical scrollbar appears. Select an item in the middle of the collection so that the scrollbar is centered and press the remove button. When the control repaints, the items and scrollbar are in a different position. I would like for the listbox to behave as it would with non-databound items. Am I better off not using databinding, or is there a solution that allows me to keep the contol bound?</p>
<p>Thanks.</p>

<p>I'm writing an application that does async loading of images onto the screen. I have it set up to be NOT concurrent (that is, it spawns a thread and executes them one at a time), so I've only overridden the <code>[NSOperation main]</code> function in my NSOperation subclass. </p>
<p>Anyway, so when I add all of these operations, I want to be able later to access the queued operations to change their priorities. Unfortunately, whenever I call <code>-[NSOperationQueue operations]</code>, all I get back is an empty array. The best part is that after putting in some console print statements, threads are still in the queue and executing (indicated by prints) despite the array being empty! </p>
<p>What gives? I also took a look at theadcount just to make sure they're all not executing at once and that does not appear to be the case. </p>
<p>Any ideas? Pulling my hair out on this one.</p>
<p>EDIT: Also worth mentioning that the same code provides a full array when run in the simulator :(</p>

<p>I have some code that raises <code>PropertyChanged</code> events and I would like to be able to unit test that the events are being raised correctly.</p>
<p>The code that is raising the events is like</p>
<pre><code>public class MyClass : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
protected void NotifyPropertyChanged(String info)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(info));
}
}
public string MyProperty
{
set
{
if (_myProperty != value)
{
_myProperty = value;
NotifyPropertyChanged("MyProperty");
}
}
}
}
</code></pre>
<p>I get a nice green test from the following code in my unit tests, that uses delegates:</p>
<pre><code>[TestMethod]
public void Test_ThatMyEventIsRaised()
{
string actual = null;
MyClass myClass = new MyClass();
myClass.PropertyChanged += delegate(object sender, PropertyChangedEventArgs e)
{
actual = e.PropertyName;
};
myClass.MyProperty = "testing";
Assert.IsNotNull(actual);
Assert.AreEqual("MyProperty", actual);
}
</code></pre>
<p>However, if I then try and chain the setting of properties together like so:</p>
<pre><code>public string MyProperty
{
set
{
if (_myProperty != value)
{
_myProperty = value;
NotifyPropertyChanged("MyProperty");
MyOtherProperty = "SomeValue";
}
}
}
public string MyOtherProperty
{
set
{
if (_myOtherProperty != value)
{
_myOtherProperty = value;
NotifyPropertyChanged("MyOtherProperty");
}
}
}
</code></pre>
<p>My test for the event fails - the event that it captures is the event for the MyOtherProperty.</p>
<p>I'm pretty sure the event fires, my UI reacts like it does, but my delegate only captures the last event to fire.</p>
<p>So I'm wondering:<br>
1. Is my method of testing events correct?<br>
2. Is my method of raising <em>chained</em> events correct? </p>

<p>This is really weird... When I open the following simple HTML document in Internet Explorer 7.0.5730.11 (on Windows Server 2003 Web Edition SP2)</p>
<pre><code><html>
<body>
<p>+</p>
</body>
</html>
</code></pre>
<p>it shows me a totally blank page. FWIW, this is just a trivial "repro" sample. In real HTML documents, I observed other, even more bizzarre effects caused by presense of the "plus" character that follows a tag.</p>
<p><strong>NB:</strong> The problem appears to be extremely ittermittent. Most of the time it does work properly (i.e. displays the "plus" character), and I still can't find any way to reproduce this problem at will.</p>
<p>Some additional details based on recent comments:</p>
<ul>
<li><p>There was no server involved. I was opening a file on disk (i.e. used <strong>file://</strong> protocol).</p></li>
<li><p>The file did not contain anything except five lines shown above. No document type declarations, no character encodings, no nothings.</p></li>
</ul>
<p>Looks like a bug in IE. Did anybody encounter the same or similar problem?</p>
<p><strong>NB:</strong> I appreciate all the responses received so far, but neither of respondednts encountered this problem. Something tells me that 99.(9)% of StackOverflow audience will not be able to reproduce it. :-)</p>

<p>I mean other than using it when required for functions, classes, if, while, switch, try-catch.</p>
<p>I didn't know that it could be done like <a href="https://stackoverflow.com/questions/241088/what-do-curly-braces-by-themselves-mean-in-java">this until I saw this SO question</a>.</p>
<p>In the above link, Eli mentioned that "They use it to fold up their code in logical sections that don't fall into a function, class, loop, etc. that would usually be folded up."</p>
<p>What other uses are there besides those mentioned? </p>
<p>Is it a good idea to use curly braces to limit the scope of your variables and expand the scope only if required (working on a "need-to-access" basis)? Or is it actually silly? </p>
<p>How about using scopes just so that you can use the same variable names in different scopes but in the same bigger scope? Or is it a better practise to reuse the same variable (if you want to use the same variable name) and save on deallocating and allocating (I think some compilers can optimise on this?)? Or is it better to use different variable names altogether?</p>

<p>but I can only see it when I select that cell otherwise it's not visible.and it work perfectly when background is white.
I am sure that I need to set a property, but I don't know which property I need to change to make this thing work.</p>

<p>I have an method which save files to the internet, it works but just slow. Then I'd like to make the user interface more smooth, so I create an NSThread to handle the slow task. </p>
<p>I am seeing a list of errors like:</p>
<pre><code>_NSAutoreleaseNoPool(): Object 0x18a140 of class NSCFString autoreleased with no pool in place - just leaking
</code></pre>
<p>Without NSThread, I call the method like:</p>
<pre><code>[self save:self.savedImg];
</code></pre>
<p>And I used the following to use NSThread to call the method:</p>
<pre><code>NSThread* thread1 = [[NSThread alloc] initWithTarget:self
selector:@selector(save:)
object:self.savedImg];
[thread1 start];
</code></pre>
<p>Thanks. </p>

<p>I would like to implement a command line interface for a Java application. This wouldn't be too difficult to do, except I would like the command line program to affect the state of another Java GUI program. So for example, I could type:</p>
<pre><code>java CliMain arg1 arg2
</code></pre>
<p>And another running GUI instance would perform an appropriate action.</p>
<p>What is the easiest way of implementing something like this?</p>

<p>I just want to know how to validate (or clean) user input in ASP.NET MVC so that an HttpRequestValidationException will not be thrown regardless of the values submitted. For example, with a text input, if the user inputs <code><BR/></code>, it will cause an exception and the Yellow Screen of Death will be shown. I don't want that. I want to catch the exception and to make visible an user friendly error in the current view, preferably with the controls loaded with the same values submitted. </p>
<p>I have found this <a href="http://www.romsteady.net/blog/2007/06/how-to-catch-httprequestvalidationexcep.html" rel="noreferrer">http://www.romsteady.net/blog/2007/06/how-to-catch-httprequestvalidationexcep.html</a>, but it is useless for my purpose. Also, I have found this <a href="http://msdn.microsoft.com/en-us/library/aa973813.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/aa973813.aspx</a> and tried to put inside a model binder but I couldn't make to work.</p>

<p>I'm sure there are a million posts about this out there, but surprisingly I'm having trouble finding something. </p>
<p>I have a simple script where I want to set the onClick handler for an <code><A></code> link on initialization of the page.</p>
<p>When I run this I <strong>immediately</strong> get a 'foo' alert box where I expected to only get an alert when I click on the link.</p>
<p>What stupid thing am I doing wrong? (I've tried click= and onClick=)...</p>
<pre><code><script language="javascript">
function init(){
document.getElementById("foo").click = new function() { alert('foo'); };
}
</script>
<body onload="init()">
<a id="foo" href=#>Click to run foo</a>
</body>
</code></pre>
<hr>
<p><strong>Edit:</strong> I changed my accepted answer to a jQuery answer. The answer by '<a href="https://stackoverflow.com/questions/249074/how-to-change-onclick-handler-dynamically/249093#249093">Már Örlygsson</a>' is technically the correct answer to my original question (<code>click</code> should be <code>onclick</code> and <code>new</code> should be removed) but I <strong>strongly discourage</strong> anyone from using 'document.getElementById(...) directly in their code - and to use <a href="http://docs.jquery.com/Tutorials:Getting_Started_with_jQuery" rel="noreferrer">jQuery</a> instead.</p>

<p>My situation: I have several components, which sometimes have changes to them, and are shared across a lot of different projects. Each project puts these in a subfolder called /depends. The depends holds a bunch of svn externals for all of our common components.</p>
<p>svn:externals is causing me a lot of time and pain.</p>
<ul>
<li>Show log on the project root folder will not show changes for svn:external folders (yet funny enough commit and update will work with svn:externals)</li>
<li>When you branch, the svn:externals are not branched.</li>
<li>Because of no branching on svn:externals, any change usually breaks the trunk.</li>
<li>Tags do not freeze their externals. This really defeats the purpose of tagging. </li>
</ul>
<p>Remember that I have several projects (Let's say 10 for this discussion each using the same externals), so keeping normal committed directories for each project would cost me a lot of merging time. </p>
<p>Is there a better alternative for my situation?</p>

<p>I'm trying to convert some strings that are in French Canadian and basically, I'd like to be able to take out the French accent marks in the letters while keeping the letter. (E.g. convert <code>é</code> to <code>e</code>, so <code>crème brûlée</code> would become <code>creme brulee</code>)</p>
<p>What is the best method for achieving this?</p>

<p>So I just love it when my application is working great in Firefox, but then I open it in IE and... Nope, please try again.</p>
<p>The issue I'm having is that I'm setting a CSS display property to either <code>none</code> or <code>table-cell</code> with JavaScript.</p>
<p>I was initially using <code>display: block</code>, but Firefox was rendering it weird without the <code>table-cell</code> property.</p>
<p>I would love to do this without adding a hack in the JavaScript to test for IE. Any suggestions?</p>
<p>Thanks.</p>

<p>I have a Django model with a large number of fields and 20000+ table rows. To facilitate human readable URLs and the ability to break down the large list into arbitrary sublists, I would like to have a URL that looks like this:</p>
<pre><code>/browse/<name1>/<value1>/<name2>/<value2>/ .... etc ....
</code></pre>
<p>where 'name' maps to a model attribute and 'value' is the search criteria for that attribute. Each "name" will be treated like a category to return subsets of the model instances where the categories match.</p>
<p>Now, this could be handled with GET parameters, but I prefer more readable URLs for both the user's sake and the search engines. These URLs subsets will be embedded on each page that displays this model, so it seems worth the effort to make pretty URLs.</p>
<p>Ideally each name/value pair will be passed to the view function as a parameter named <code>name1</code>, <code>name2</code>, etc. However, I don't believe it's possible to defined named patterns via a regex's matched text. Am I wrong there?</p>
<p>So, it seems I need to do something like this:</p>
<pre><code>urlpatterns = patterns('',
url(r'^browse/(?:([\w]+)/([\w]+)/)+$', 'app.views.view', name="model_browse"),
)
</code></pre>
<p>It seems this should match any sets of two name/value pairs. While it matches it successfully, it only passes the last name/value pair as parameters to the view function. My guess is that each match is overwriting the previous match. Under the guess that the containing (?:...)+ is causing it, I tried a simple repeating pattern instead:</p>
<pre><code>urlpatterns = patterns('',
url(r'^browse/([\w]+/)+$', 'app.views.view', name="model_browse"),
)
</code></pre>
<p>... and got the same problem, but this time <code>*args</code> only includes the last matched pattern.</p>
<p>Is this a limitation of Django's url dispatcher, and/or Python's regex support? It seems either of these methods should work. Is there a way to achieve this without hardcoding each possible model attribute in the URL as an optional (.*) pattern?</p>

<p>First, a couple operating parameters:</p>
<ul>
<li>.NET development using Visual Studio 2005/2008</li>
<li>TortoiseSVN client</li>
</ul>
<p>I've only primarily worked with Visual Source Safe and SourceGear Vault source control systems. In each, I map the root of the repository to a local working directory. For example:</p>
<pre><code>$/ --> C:\source
</code></pre>
<p>As long as the local directory exists, I've got my "working copy" (svn) or "working folder" (VSS) set up.</p>
<p>To work on a new project that is already in the source code repository I need to "get the latest" (VSS) version of that project's directory.</p>
<p>When I go into any child directory in the repository and "Get Latest" (i.e. svn checkout) the client will automatically create the complete directory hierarchy for me, mirroring the structure on my local disk. Thus when I get latest of</p>
<pre><code>$/foo/bar/project1
</code></pre>
<p>it is created on the drive at</p>
<pre><code>C:\source\foo\bar\project1
</code></pre>
<p>In subversion, when I check out a directory, I must specify the working copy directory location. If I want to properly mirror my working copy directory structure to match the repository I have to either manually construct every child directory in the path or do a checkout of the repository root to the working copy root, getting everything in the repository.</p>
<p><strong>Is there a way to get a repository directory down in the hierarchy such that it will be created in a matching local working copy directory structure without all the manual intervention?</strong></p>
<p>This isn't a problem with a small repository, but in most cases, I don't need a large percentage of the source repository. It's imperative that the physical structure is maintained in order for file references to projects and resources not to break. Plus the disk cost of SVN is twice the actual source size given all the working base copies of the files.</p>
<p>I'm currently using Tortoise. Is it possible there are other SVN clients that will do what I'm looking for?</p>

<p>I am working on a business problem in C#.NET. I have two classes, named C and W that will be instantiated independently at different times.</p>
<p>An object of class C needs to contain references to 0 ... n objects of class W, i.e. a C object can contain up to n W objects.</p>
<p>Each W object needs to contain a reference to exactly 1 object of class C, i.e. a W object is contained in one C object.</p>
<p>An object of class C is usually instantiated first. At a later point, its W contents are discovered, and instantiated. At this later point, I need to cross reference the C and W objects to each other.</p>
<p>What is a good design pattern for this? I actually have cases where I have three or four classes involved but we can talk about two classes to keep it simple.</p>
<p>I was thinking of something simple like:</p>
<pre><code>class C
{
public List<W> contentsW;
}
class W
{
public C containerC;
}
</code></pre>
<p>This will work for the moment but I can foresee having to write a fair amount of code to keep track of all the references and their validity. I'd like to implement code down the road to do shallow refreshes of just the container and deep refreshes of all referenced classes. Are there any other approaches and what are their advantages?</p>
<p>Edit on 11/3:
Thanks to all for the good answers and good discussion. I finally chose jop's answer because that came closest to what I wanted to do, but the other answers also helped. Thanks again!</p>

<p>I have a two-level hierarchy displayed in a WPF TreeView, but I only want the child nodes to be selectable - basically the top level nodes are for categorisation but shouldn't be selectable by themselves. </p>
<p>Can I achieve this?</p>

<p>What's the most elegant way of implementing a DropDownList in <code>ASP.NET</code> that is editable without using 3rd party components.</p>
<p>As a last resort I will probably try using a <code>TextBox</code> with an <code>AutoCompleteExtender</code> with an image to 'drop down' the list; or a <code>TextBox</code> overlapping a HTML Select with some JavaScript to fill values from the Select to the <code>TextBox</code>. But I'm really hoping there is a more terse and maintainable solution.</p>
<p>Thanks in advance.</p>

<p>I need a webserver to serve up very simple POST/GET requests as JSON. I don't need MVC, Rails, Django. I need something that takes up very little memory, preferrably around 5K per reqeust. The webserver will talk to backend services like Scribe using Facebook Thrift. Each http request will also access a SQLLite database, one for each user and user's data do not overlap. It will serve up static html files as well as the json webservice.</p>
<p>I am considering the following:</p>
<ul>
<li>Njinx with PHP,</li>
<li>Kepler from Lua,</li>
<li>rolling my own with libevent or libev perhaps calling out to Lua, or</li>
<li>MochiWeb.</li>
</ul>
<p>Which of these options are best and what other options are out there? I can use PHP, python, or Lua for basic scripting and even could do basic C. I am leaning towards some sort of Erlang solution.</p>

<p>I'm a fan of extension methods in C#, but haven't had any success adding an extension method to a static class, such as <code>Console</code>.</p>
<p>For example, if I want to add an extension to <code>Console</code>, called '<code>WriteBlueLine</code>', so that I can go:</p>
<pre><code>Console.WriteBlueLine("This text is blue");
</code></pre>
<p>I tried this by adding a local, public static method, with <code>Console</code> as a '<code>this</code>' parameter... but no dice!</p>
<pre><code>public static class Helpers {
public static void WriteBlueLine(this Console c, string text)
{
Console.ForegroundColor = ConsoleColor.Blue;
Console.WriteLine(text);
Console.ResetColor();
}
}
</code></pre>
<p>This didn't add a '<code>WriteBlueLine</code>' method to <code>Console</code>... am I doing it wrong? Or asking for the impossible?</p>

<p>I have a script to extract certain data from a much bigger table, with one field in particular changing regularly, e.g.</p>
<pre><code>SELECT CASE @Flag WHEN 1 THEN t.field1 WHEN 2 THEN t.field2 WHEN 3
THEN t.field3 END as field,
...[A bunch of other fields]
FROM table t
</code></pre>
<p>However, the issue is now I want to do other processing on the data. I'm trying to figure out the most effective method. I need to have some way of getting the flag through, so I know I'm talking about data sliced by the right field.</p>
<p>One possible solution I was playing around with a bit (mostly to see what would happen) is to dump the contents of the script into a table function which has the flag passed to it, and then use a SELECT query on the results of the function. I've managed to get it to work, but it's significantly slower than...</p>
<p>The obvious solution, and probably the most efficient use of processor cycles: to create a series of cache tables, one for each of the three flag values. However, the problem then is to find some way of extracting the data from the right cache table to perform the calculation. The obvious, though incorrect, response would be something like</p>
<pre><code>SELECT CASE @Flag WHEN 1 THEN table1.field WHEN 2 THEN table2.field WHEN 3
THEN table3.field END as field,
...[The various calculated fields]
FROM table1, table2, table3
</code></pre>
<p>Unfortunately, as is obvious, this creates a massive cross join - which is not my intended result at all.</p>
<p>Does anyone know how to turn that cross join into an "Only look at x table"? (Without use of Dynamic SQL, which makes things hard to deal with?) Or an alternative solution, that's still reasonably speedy?</p>
<p>EDIT: Whether it's a good reason or not, the idea I was trying to implement was to not have three largely identical queries, that differ only by table - which would then have to be edited identically whenever a change is made to the logic. Which is why I've avoided the "Have the flag entirely separate" thing thus far...</p>

<p>I've been using virtualenv lately while developing in python. I like the idea of a segregated development environment using the <strong>--no-site-packages</strong> option, but doing this while developing a PyGTK app can be a bit tricky.
The PyGTK modules are installed on Ubuntu by default, and I would like to make a virtualenv (with --no-site-packages) aware of specific modules that are located elsewhere on the system.</p>
<p>What's the best way to do this? Or should I just suck it up and drop the --no-site-packages option?</p>

<p>Why don't we see C-like languages that allow for callables with polymorphism in the return type? I could see how the additional type inference would be a hurdle, but we have <a href="http://en.wikipedia.org/wiki/Type_inference" rel="nofollow noreferrer">plenty of languages</a> with full-fledged type inference systems (that work for varying levels of "work").</p>
<p><strong>Edit:</strong> By return type polymorphism I mean overloading the function signature only in the return type. For example, C++ and Java only allow overloading in the type of the formal parameters, not in the return type.</p>

<p>Excuse me if I'm off on my terminology, I only have around 2.4 years of programming experience, mostly in .NET.</p>
<p>Currently I'm one of two .NET developers in a mainframe shop, the other developer set the standards and is a great coder with a lot more experience plus a CS degree(I am 100% self taught). </p>
<p>We use custom collections for every application, recently since .NET 2.0 I've got him using generics instead of ArrayLists, and eyeball performance they seem to do great. We developed an automated program that uses SQLDMO to connect to databases and will create the base Datalayer and business layers for any objects we'd like, plus it handles logical deletes et cetera. </p>
<p>When performance is what you optimize for, when can you justify NOT using a custom collection and writing a custom sort for it? Currently we use hard coded sorts because everything we've seen is a good deal slower, since most other options use reflection or bloated datasets/LINQ(is it still as slow as it was a year ago compared to custom collections?).</p>
<p>Does anyone else work strictly with custom generic collections instead of going the easy route? Is the performance sacrifice as significant as I have been led to believe? Being that I am still in my infant stages of my development career, I'd say the next logical step is for me to start benchmarking things myself, but I wanted to get the opinion of other professionals as well....So, how does everyone else do it? Am one of the only people who actually strictly use custom collections over the much quicker and easier to create solutions? </p>
<p>All opinions would be greatly appreciated. </p>
<p><strong>EDIT:</strong> Sorry about the terminology, I knew I would get something a little off. What I meant by custom collections was indeed, using custom classes, and a custom collection class that inherits List(Of T) and also implements IComparable to handle sorting.</p>

<p>How do I take an efficient simple random sample in SQL? The database in question is running MySQL; my table is at least 200,000 rows, and I want a simple random sample of about 10,000.</p>
<p>The "obvious" answer is to:</p>
<pre><code>SELECT * FROM table ORDER BY RAND() LIMIT 10000
</code></pre>
<p>For large tables, that's too slow: it calls <code>RAND()</code> for every row (which already puts it at O(n)), and sorts them, making it O(n lg n) at best. Is there a way to do this faster than O(n)?</p>
<p><em>Note</em>: As Andrew Mao points out in the comments, If you're using this approach on SQL Server, you should use the T-SQL function <code>NEWID()</code>, because RAND() <a href="http://msdn.microsoft.com/en-us/library/ms177610.asp" rel="noreferrer">may return the same value for all rows</a>.</p>
<p><em>EDIT: 5 YEARS LATER</em></p>
<p>I ran into this problem again with a bigger table, and ended up using a version of @ignorant's solution, with two tweaks:</p>
<ul>
<li>Sample the rows to 2-5x my desired sample size, to cheaply <code>ORDER BY RAND()</code></li>
<li>Save the result of <code>RAND()</code> to an indexed column on every insert/update. (If your data set isn't very update-heavy, you may need to find another way to keep this column fresh.)</li>
</ul>
<p>To take a 1000-item sample of a table, I count the rows and sample the result down to, on average, 10,000 rows with the the frozen_rand column:</p>
<pre><code>SELECT COUNT(*) FROM table; -- Use this to determine rand_low and rand_high
SELECT *
FROM table
WHERE frozen_rand BETWEEN %(rand_low)s AND %(rand_high)s
ORDER BY RAND() LIMIT 1000
</code></pre>
<p>(My actual implementation involves more work to make sure I don't undersample, and to manually wrap rand_high around, but the basic idea is "randomly cut your N down to a few thousand.")</p>
<p>While this makes some sacrifices, it allows me to sample the database down using an index scan, until it's small enough to <code>ORDER BY RAND()</code> again.</p>

<p>I was just watching a video on MSDN Channel 9 which can be found <a href="http://channel9.msdn.com/posts/Dan/Lucian-Wischik-and-Lisa-Feigenbaum-Whats-new-in-Visual-Basic-10/" rel="noreferrer">here</a>, about some of the new features in Visual Basic 10. Now I like most of the new features, some of which have been long awaited(auto properties and Collection Initializers), one that caught my eye was the multiline lambdas like in C#. </p>
<p>In the video he used an example like this:</p>
<pre><code>Dim scores = {10,20,30,40,50}
Dim thread as new Threading.Thread(Sub()
For Each o in scores
console.writeline(o)
Next
End Sub)
</code></pre>
<p>Now I like VB in all it verbosity but I'm just a bit worried that writing sub...end sub inline could get a bit messy, I can see some merit in inlining when you are writing C# when you only have to use something like c => {....} and you can cut out a lot of code.</p>
<p>What are your throughts of multiline lambdas in VB?</p>
<p>Would you find them useful and where?</p>

<p>I'm writing a utility in Python that will attach changed files in Subversion to an email and send it when a subset of folders that are under source control in SVN have been changed. I am using the pysvn library to access the repository.</p>
<p>I have a copy of the files on my local file system and I do an update to check if the files have changed since the last time the utility was run.</p>
<p>I am at the point where I am translating the path names in SVN to the path names on my local copy.</p>
<p>Currently I have written the following to do the job:</p>
<pre><code>def formatPaths(self, paths):
newPaths = list()
for path in paths:
path = path[len(self.basePath):]
path = path.replace("/", "\\")
newPaths.append(path)
return newPaths
</code></pre>
<p>self.basePath would be something like "/trunk/project1" and I'm looking to just get the relative path of a subset of folders (I.e. folder1 under "/trunk/project1").</p>
<p>Is this a good way to solve this problem or is there some magical function I missed?</p>

<p>I am building a utility page for a web app that I am working on. I have an element that I want to use as a "console" of sorts.</p>
<p>I get entries for the console via Ajax calls (using prototype's <code>Ajax.PeriodicalUpdater</code>).</p>
<p>The problem I'm having is that when I insert new lines to the bottom of the "console", the scrollbar stays in the initial position (so I always see the top lines unless I manually scroll down).</p>
<p>How can I make the scrollbar automatically stay at the bottom?</p>
<p>I am using prototype for a few libraries that require it in this project, so I would prefer to stick with that or regular javascript if possible.</p>
<p>Just as a note, I already tried this:</p>
<pre><code>onComplete: function() {
$('console').scrollTop = $('console').scrollHeight;
}
</code></pre>
<p>It <em>almost</em> works, except that it is always "one step behind", and I can't see the most recent item.</p>
