411,575 | <p>Given a table such as:</p>
<pre><code>CREATE TABLE dbo.MyTestData (testdata varchar(50) NOT NULL)
ALTER TABLE dbo.MyTestData WITH NOCHECK ADD CONSTRAINT [PK_MyTestData] PRIMARY KEY CLUSTERED (testdata)
</code></pre>
<p>And given that we want a unique list of 'testdata' when we are done gathering items to be added from a list of external data with known duplicates... When performing an insert stored procedure should the procedure be written to test for existence or should it just allow for error? What's the most common practice? I've always performed the test for existence but was debating this last night... </p>
<pre><code>CREATE PROCEDURE dbo.dmsInsertTestData @ptestdata VarChar(50)

IF NOT EXISTS(SELECT testdata FROM dbo.MyTestData WHERE testdata=@ptestdata)
BEGIN
INSERT INTO dbo.MyTestData (testdata ) VALUES (@ptestdata)

411,628 | <p>I am trying to learn ASP.NET MVC and I hit this problem: I have a "view product details" form that I want to reuse as an add/edit form. (When you look at the product details, if you have the rights to do it an Edit link should appear; it should redisplay the same form, but with the textbox fields enabled this time.)</p>
<p>Right now the Details view looks something like this:</p>
<pre><code><% var product = ViewData.Model; %>
<table>
<tr>
<td>Name</td>
</tr>
<tr>
<td><%= Html.TextBox("Name", product.Name, new { size = "50", disabled = "disabled"})%></td>
</tr>
</code></pre>
<p>Is there a way I could reuse it without putting too much logic in the view? For example, I will need to remove the <code>disabled = "disabled"</code> part (but the <code>size</code> part needs to stay there), to put everything inside a form and so on.</p>
<p>If it can't be done, that's fine, I'm just trying not to repeat the same thing several times in case I need to change it (and I will).</p>

411,631 | <p>I've got a bunch of <a href="http://www.unicode.org/charts/PDF/U1F000.pdf" rel="nofollow noreferrer">unicode characters</a> from U1F000 and upwards, and I'm wondering how to represent them in Java. A Java unicode escape is on the form "\uXXXX" and the Java language specification says that "Representing supplementary characters requires two consecutive Unicode escapes". How does that apply to U1F000?</p>
<pre><code>String mahjongTile = "\u0001\uf000";

<p>Does not <strong>seem</strong> to work (I only get two blank squares), but that may be a font-glitch, I presume.</p>

<p>After innocent operations like typing text or moving some files in Navigator view or saving, it sometimes starts "waiting on background operation", and eats one CPU core, shuffling back and forth tens of megabytes of memory.</p>

411,646 | <p>I've been reading a lot lately about how joins in DB queries slow things down. Evidently Google App Engine doesn't even allow them.</p>
<p>I'm wondering how people design an app with no joins though. For example I'm working on an app that has <code>contacts</code> and <code>organizations</code>. A contact can be in many organizations and an organization can have many contacts. How would it be possible to have that relationship without a third table that connects the two entities...</p>
<pre><code>contacts --< contacts_organizations >-- organizations
</code></pre>
<p>Does it mean that in GAE you can't have a many-to-many relationship? You just leave out functionality that would require a join?</p>
<p>I guess you could have a TEXT <code>organizations</code> column in the <code>contacts</code> table containing a space-separated list of the organization IDs for each contact. That seems a little weird though.</p>

411,724 | <p>I have a parts database that I am going to be constantly querying for a quoting system. The parts database has 1,400,000+ records in it. The users are just going to start typing part numbers, which they expect the system to be able to find after only a few characters, so I need to be able to do a wildcard search, something like:</p>
<pre><code>SELECT NeededFields FROM Parts WHERE PartNumber LIKE 'ML%'
</code></pre>
<p>Is there any kind of optimization that I can perform to try to wring the most performance out of this type of query? I have the PartNumber field indexed, but I'm not sure if that is the best that I can get. I'd be willing to consider alternate indexing structures built into the database separate from SQL indexes too. The primary key is a Guid, but I need this for replication and because of specific data structures that I use.</p>

<p>The start() function <strong>is</strong> used. The program uses the <a href="http://expat.sourceforge.net/" rel="nofollow noreferrer">expat</a> XML parser which works with callbacks. You give the parser a function:</p>

<p>and the parser calls it back at some points. This is a very common idiom in C and I wonder why splint complains.

<p><strong>edit</strong>: adding more info</p>
<p>The expressions being or'd are coming from the method below, which execute just fine. if there is a better way to or the results I am all ears. Also, I do not know how many are being or'd in advance.</p>
<pre><code>public static Expression<Func<T, bool>> FilterExpression(string filterBy, object Value, FilterBinaryExpression binaryExpression)

param);

<p><strong>edit</strong>: adding even more info</p>
<p>Alternatively, is there a better way to do an or? Currently the .Where(constraint) works just fine where constraint is of type Expression>. How can i do where(constraint1 or constraint2) (to the constraint n'th)</p>

411,746 | <p>In a Rails 2.2 project, I'm having users put together a list of projects into a portfolio object (i.e.: <code>PortfolioHasManyProjects</code>). On the page is a Rails form for regular text, titles etc., as well as 2 sortable lists; the lists are used for dragging projects from the global-project-list into your portfolio-project-list.</p>
<p>It is similar to what's done here:
<a href="http://ui.jquery.com/latest/demos/functional/#ui.sortable" rel="nofollow noreferrer">http://ui.jquery.com/latest/demos/functional/#ui.sortable</a>.</p>
<p>I have the portfolio list (#drag_list) updating on change and submitting its serialized data through an AJAX call.
<strong>This is done in the application.js file:</strong></p>
<pre><code>jQuery.ajaxSetup({
'beforeSend': function(xhr) {xhr.setRequestHeader("Accept", "text/javascript")}
})
jQuery.fn.submitDragWithAjax = function() {
this.submit(function() {
$.post(this.action, $("#drag_list").sortable('serialize'), null, "script");
return false;
})
return this;
};
$(document).ajaxSend(function(event, request, settings) {
if (typeof(AUTH_TOKEN) == "undefined") return;
// settings.data is a serialized string like "foo=bar&baz=boink" (or null)
settings.data = settings.data || "";
settings.data += (settings.data ? "&" : "") + "authenticity_token=" + encodeURIComponent(AUTH_TOKEN);
});
/-------------------------------------------/
$(document).ready(function(){
$(".ajax_drag").submitDragWithAjax();
$("#drag_list").sortable({
placeholder: "ui-selected",
revert: true,
connectWith:["#add_list"],
update : function () {
$("#drag_list").submit();
}
});
$("#add_list").sortable({
placeholder: "ui-selected",
revert: true,
connectWith:["#drag_list"]
});
</code></pre>
<p>Here is where things got tricky. I wasn't sure how to deal with the serialized data and have it submit with the form to the controller in the <code>new.html.erb</code> file. So what I did was have the <code>new.js.erb</code> insert hidden form fields into <code>new.html.erb</code> with the data that I would extract in the controller.</p>
<p><strong>here's the new.js.erb:</strong></p>
<pre><code>$("#projects").html("");
<% r = params[:proj] %>
<% order=1 %>
<% for i in r %>
$("#projects").append("<input type=hidden name=proj[<%=order%>] value=<%=i%> />");
<% order=order+1 %>
<% end %>
</code></pre>
<p><strong>which edits new.html.erb:</strong></p>
<pre><code><h1>New portfolio</h1>
<h2>The List</h2>
<div class="list_box">
<h3>All Available Projects</h3>
<%= render :partial => "projects/add_list" %>
</div>
<div class="list_box">
<h3>Projects currently in your new portfolio</h3>
<%= render :partial => "projects/drag_list" %>
</div>
<div style="clear:both"></div>
<br/>
<br/>
<h2>Portfolio details</h2>
<% form_for(@portfolio) do |f| %>
<%= f.error_messages %>
<h3>Portfolio Name</h3>
<p>
<%= f.text_field :name %>
</p>
<h3>URL</h3>
<p>
<%= f.text_field :url %>
</p>
<h3>Details</h3>
<p>
<%= f.text_area :details %>
</p>
<p>
<div id="projects">
<input type="hidden" name="proj" value="" />
</div>
<%= f.submit "Create" %>
</p>
<% end %>
</code></pre>
<p>The form then submits to the create method in the portfolio controller:</p>
<pre><code> def new
@projects = Project.find(:all)
@portfolio = Portfolio.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @portfolio }
format.js
end
end
def create
@portfolio = Portfolio.new(params[:portfolio])
proj_ids = params[:proj]
@portfolio.projects = []
@portfolio.save
proj_ids.each {|key, value| puts "Key:#{key} , Value:#{value} " }
proj_ids.each_value {|value| @portfolio.projects << Project.find_by_id(value) }
respond_to do |format|
if @portfolio.save
flash[:notice] = 'Portfolio was successfully created.'
format.html { render :action => "index" }
format.xml { render :xml => @portfolio, :status => :created, :location => @portfolio }
else
format.html { render :action => "new" }
format.xml { render :xml => @portfolio.errors, :status => :unprocessable_entity }
end
end
end
</code></pre>
<hr>
<p><strong>So finally my question:</strong></p>
<ol>
<li><p>Is this a proper way of doing this? For some reason I feel it isn't, mostly because doing everything else in Rails seemed so much easier and intuitive. This works, but it was hell to get it to. There has to be a more <em>elegant</em> way of sending serialized data to the controller through AJAX calls.</p></li>
<li><p>How would I call for different AJAX actions on the same page? Let's say I had a sortable and an autocomplete AJAX call, could I have a <code>sortable.js.erb</code> and <code>autocomplete.js.erb</code> and call them from any file? I'm not sure how to setup the controllers to respond to this.</p></li>

411,752 | <p>What is the best way to generate a string of <code>\t</code>'s in C#</p>
<p>I am learning C# and experimenting with different ways of saying the same thing.</p>
<p><code>Tabs(uint t)</code> is a function that returns a <code>string</code> with <code>t</code> amount of <code>\t</code>'s</p>
<p>For example <code>Tabs(3)</code> returns <code>"\t\t\t"</code></p>
<p>Which of these three ways of implementing <code>Tabs(uint numTabs)</code> is best?</p>
<p>Of course that depends on what "best" means.</p>
<ol>
<li><p>The LINQ version is only two lines, which is nice. But are the calls to Repeat and Aggregate unnecessarily time/resource consuming?</p>
</li>
<li><p>The <code>StringBuilder</code> version is very clear but is the <code>StringBuilder</code> class somehow slower?</p>
</li>
<li><p>The <code>string</code> version is basic, which means it is easy to understand.</p>
</li>
<li><p>Does it not matter at all? Are they all equal?</p>
</li>
</ol>
<p>These are all questions to help me get a better feel for C#.</p>
<pre><code>private string Tabs(uint numTabs)
{
IEnumerable<string> tabs = Enumerable.Repeat("\t", (int) numTabs);
return (numTabs > 0) ? tabs.Aggregate((sum, next) => sum + next) : "";
}
private string Tabs(uint numTabs)
{
StringBuilder sb = new StringBuilder();
for (uint i = 0; i < numTabs; i++)
sb.Append("\t");
return sb.ToString();
}
private string Tabs(uint numTabs)
{
string output = "";
for (uint i = 0; i < numTabs; i++)
{
output += '\t';
}
return output;
}
</code></pre>

<p>I get the following error:</p>
<p>'MySQL server has gone away'</p>
<p>(the same error I had when max_allowed_packet was set to 1MB)</p>
<p>there must be some other setting that doesn´t allow me to handle files bigger than 16MB</p>

411,761 | <p>Is it possible to have a variable number of fields using django forms?</p>
<p>The specific application is this:</p>
<p>A user can upload as many pictures as they want on the image upload form. Once the pictures are uploaded they are taken to a page where they can give the pictures a name and description. The number of pictures will depend on how many the user has chosen to upload.</p>
<p>So <strong>how do I get django to generate a form using a variable number of input fields</strong> (which could be passed as an argument if necessary)?</p>
<p><strong>edit:</strong> a few things have changed since the <a href="http://www.b-list.org/weblog/2008/nov/09/dynamic-forms/" rel="noreferrer">article mentioned in jeff bauer's answer</a> was written. </p>
<p>Namely this line of code which doesn't seem to work:</p>
<pre><code># BAD CODE DO NOT USE!!!
return type('ContactForm', [forms.BaseForm], { 'base_fields': fields })
</code></pre>
<p>So here is what I came up with...</p>
<h1>The Answer I used:</h1>
<pre><code>
from tagging.forms import TagField
from django import forms
def make_tagPhotos_form(photoIdList):
"Expects a LIST of photo objects (ie. photo_sharing.models.photo)"
fields = {}
for id in photoIdList:
id = str(id)
fields[id+'_name'] = forms.CharField()
fields[id+'_tags'] = TagField()
fields[id+'_description'] = forms.CharField(widget=forms.Textarea)
return type('tagPhotos', (forms.BaseForm,), { 'base_fields': fields })
</code></pre>
<p>note tagging is not part of django, but it is free and very useful. check it out: <a href="http://code.google.com/p/django-tagging/" rel="noreferrer">django-tagging</a></p>

411,777 | <p>I'd like to know how one would create an application that starts in the background. I'm currently creating a webserver in C as a little project, both to learn some old C and Linux Socket Programming. But my current concern is:</p>
<ul>
<li>How do I get the current process number?</li>
</ul>
<p>I want to get this because when I start the process, I want to display the process number for the user who starts the service.</p>
<ul>
<li>My second problem is, how do I start my application as a Daemon to run in the background?</li>
</ul>
<p>Any references, tutorials and/or videos on how I'd do this is appreciated!</p>
<hr>
<p>Maybe I was a little bit unclear; I want to get the Process ID from within C. So, do I need to create a shell script for my application or can I do this from C?</p>

411,823 | <p>I'm just learning Qt with C++. I have successfully implemented signals and slots to trap standard events like <code>ButtonPushed()</code>, etc. However, I want to have a function called when I mouse over and mouse out of a <code>QLabel</code>. It looks like <a href="http://doc.qt.io/qt-4.8/qhoverevent.html" rel="nofollow noreferrer">QHoverEvent</a> will do what I need, but I can't seem to find any tutorials or examples on how to implement this. Is it done the same way as signals and slots?. I tried:</p>
<pre><code>connect(ui.lbl_test, SIGNAL(QHoverEvent), this, SLOT(TestFunc(QEvent::Type type, const QPoint & pos, const QPoint & oldPos)));
</code></pre>
<p>.. but the function didn't get called when I hovered over the label.</p>
<p>Here is the function, listed in the header file as a public slot:</p>
<pre><code>void MyDialog::TestFunc(QEvent::Type type, const QPoint & pos, const QPoint & oldPos) {
QMessageBox::information(this, tr("Hey"), tr("Listen!"));
}
</code></pre>
<p>Can anyone help me figure this out or point me to a good example?</p>
<p>EDIT:</p>
<p>After reading a post below, I found no <code>setFlag()</code> member to call for my label widget, but I did try:</p>
<pre><code> ui.lbl_test->setMouseTracking(true);
connect(ui.lbl_test, SIGNAL(ui.lbl_test->mouseMoveEvent()), this, SLOT(TestFunc(QMouseEvent *event)));
</code></pre>
<p>And updated <code>TestFunc()</code> accordingly. But still nothing happens when I mouse over.</p>
<p>After looking I am not sure <code>QLabel</code> even inherits the mouseMoveEvent() even from <code>QWidget</code>. If this is true, is there a widget that does, or a list of objects that inherit it somewhere?. All I can tell from the documentation on their site is how many inherited functions an object has..</p>

411,825 | <p>I've have just been stumped with this problem for an hour and I annoyingly found the problem eventually.</p>
<p><strong>THE CIRCUMSTANCES</strong></p>
<p>I have a table which users a string as a primary key, this table has various many to one and many to many relationships all off this primary key.</p>
<p>When searching for multiple items from the table all relationships were brought back. However whenever I tried to get the object by the primary key (string) it was not bringing back any relationships, they were always set to 0. </p>
<p><strong>THE PARTIAL SOLUTION</strong></p>
<p>So I looked into my logs to see what the SQL was doing and that was returning the correct results. So I tried various things in all sorts of random ways and eventually worked out it was. The case of the string being passed into the get method was not EXACTLY the same case as it was in the database, so when it tried to match up the relationship items with the main entity it was finding nothing <strong>(Or at least NHIbernate wasn't because as I stated above the SQL was actually returning the correct results)</strong></p>
<p><strong>THE REAL SOLUTION</strong></p>
<p>Has anyone else come across this? If so how do you tell NHibernate to ignore case when matching SQL results to the entity? It is silly because it worked perfectly well before now all of a sudden it has started to pay attention to the case of the string.</p>

<p>Suppose now we expand the matrix to this form:</p>
<pre><code>0 1 2 3 4 5 6 7 8 9
1 . X X . . . . . .
2 . X X X . . X . .
3 . . . . . X X X .

6 . X . . . . . . .
7 . X . . . . . . .
8 . . . . X X . . .
9 . . . . X X . . .
</code></pre>
<p>As you can see we now have 4 centers of mass, for 4 different clusters.</p>
<p>We already know how to find a center of mass given that only one exists, if we run that algorithm on this matrix we'll get some point in the middle of the matrix which does not help us.</p>
<p>What can be a good, correct and fast algorithm to find these clusters of mass?</p>

Bytes=list_to_binary(reverse(SoFar)),
io:format("~p~n",[Bytes])
end.
</code></pre>
<p>Now, no matter what I send from the client, I ALWAYS get <code>[<<0,0,0,4,0,0,0,32>>]</code> as the response. I can try writing bytes to the socket directly instead of ints, and I get the same thing. I can write more or less data, same result. UTF strings same result. Even when specifying "4" as the packet header length, I just get the same consistent result of <code>[<<0,0,0,32>>]</code> instead. I don't understand what I'm doing wrong here.</p>

411,876 | <p>I'm converting an algorithm I wrote in Java to Objective-C. In java the BigDecimal class handles base-10 numbers and can take the primitive double as a constructor arg. In Cocoa's NSDecimalNumber class, however, there is no direct way to construct an instance using a primitive double.</p>
<p>Currently I'm using this (smelly) hack:</p>
<pre><code> [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:@"%1.38f", number]];
</code></pre>
<p>Is there a better way?</p>

411,896 | <p>I'm trying to solve the problem of passing a 2-dimensional table into JavaScript AJAX application through SOAP web services. I'm trying to pass data into JavaScript web page through ASP.NET web service declared with following attributes:</p>
<pre><code>[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]

<p>I need a complex type to be passed into the JavaScript:</p>

</code></pre>
<p>...
function RefreshPayRates() {

411,902 | <p>I am trying to port my first Django 1.0.2 application to run on OSX/Leopard with Apache + mod_python 3.3.1 + python 2.6.1 (all running in 64-bit mode) and I am experiencing an occasional error when uploading a file that was not present when testing with the Django development server. </p>
<p>The code for the upload is similar to what described in the Django documentation:</p>
<pre><code>class UploadFileForm(forms.Form):
file = forms.FileField()
description = forms.CharField(max_length=100)
notifygroup = forms.BooleanField(label='Notify Group?', required=False)
def upload_file(request, date, meetingid ):
print date, meetingid
if request.method == 'POST':
print 'before reloading the form...'
form = UploadFileForm(request.POST, request.FILES)
print 'after reloading the form'
if form.is_valid():
try:
handle_uploaded_file(request.FILES['file'], request.REQUEST['date'], request.REQUEST['description'], form.cleaned_data['notifygroup'], meetingid )
except:
return render_to_response('uploaded.html', { 'message': 'Error! File not uploaded!' })
return HttpResponseRedirect('/myapp/uploaded/')
else:
form = UploadFileForm()
return render_to_response('upload.html', {'form': form, 'date':date, 'meetingid':meetingid})
</code></pre>
<p>This code normally works correctly, but sometimes (say, once every 10 uploads) and after a fairly long waiting time, it fails with the following error:</p>

411,921 | <p>This is probably one of the most common tasks / problems when programming; You need to store the configuration of your application somewhere.</p>
<p>While I'm trying to create a webserver or other applications, I'd like to keep the code as clean as possible since my main interest in programming is architecture. This results in me wanting to store configurations in a file which can be changed without having to re-compile the software.</p>
<p>I'm not here to re-invent the wheel or anything like that, so what I'd like to do is creating a Configuration reader in C on *nix. The configuration might look a lot like any other software's configuration; Apache, vsftpd, MySQL, etc.</p>
<p>The basic question is: How do you read from a textfile and process each line efficiently (in pure C)? Do I need to use <code>fgetc()</code> and process each char?</p>

411,945 | <p>I'm new to java but I would have thought this was pretty straight foward. I display a JDialog for user input when importing data from a text file but the dialog isn't being painted properly on other computers.</p>
<p>On my computer if I run the program from within NetBeans or from the command prompt then the dialog displays properly. If I run the program on the computer it's supposed to be running on then the inside of the dialog isn't painted - all I see is the border of the dialog then the screen behind it where the controls should be. This computer is running XPSP2 and jre6 update 11.</p>

411,954 | <p>Over the years most web developers will have built an arsenal of tools or "tools of the trade". Recently I discovered rsync and I am surprised how I managed to live without it all these years. What tools do you consider to be the most compelling? Please stick to the ones you use on a regular basis and swear by. They can also be frameworks, platforms, editors and whatever else you think web developers ought to be using (jquery, joomla, xdebug, vi, notepad++, etc).</p>
<p>I'll start off with a couple:</p>
<ol>
<li><a href="http://samba.anu.edu.au/ftp/rsync/rsync.html" rel="noreferrer">rsync</a> - 'One click' sync to live servers or vice-versa</li>
<li><a href="http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html" rel="noreferrer">mysqldump</a> - used alongside rsync to sync the databases</li>
<li><a href="https://www.squarefree.com/bookmarklets/webdevel.html" rel="noreferrer">test styles bookmarklet</a> - live css editor bookmarklet which beats the heck out of the 'edit > save > reload' cycle by allowing live editing.</li>
<li><a href="https://www.squarefree.com/bookmarklets/webdevel.html" rel="noreferrer">javascript shell</a> - javascript shell window attached to a window</li>
<li><a href="http://www.getfirebug.com/" rel="noreferrer">firebug</a> - advanced javascript/css/dom debugger</li>
<li><a href="http://pear.php.net/package/PHP_Shell/" rel="noreferrer">php-shell</a> - I use this regularly for quickly testing statements, functions, classes or scripts</li>
<li><a href="http://css-discuss.incutio.com/" rel="noreferrer">CSS-Discuss Wiki</a> - I'd be surprised if you couldn't find a solution to your CSS problem on this wiki (in which case you should add it)</li>
<li><a href="http://media.24ways.org/2007/17/fontmatrix.html" rel="noreferrer">Font Matrix</a> - Helps me choose font stacks</li>
<li><a href="http://www.phpmyadmin.net/" rel="noreferrer">PHPMyAdmin</a> - I'm certain everyone uses this for managing their MySQL databases but thought I'd add it to the list for good measure</li>
</ol>
<p>Even though I have highlighted tools in the LAMP environment, you may mention tools you use in your environment.</p>

411,974 | <p>My objective is to retry an asynchronous HttpWebRequest when it fails.</p>
<p>When I <a href="http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.abort.aspx" rel="nofollow noreferrer">Abort()</a> an HttpWebRequest, I cannot BeginGetResponse() again. So the only way to request again probably is recreate the HttpWebRequest object. It seems to require a lot of work since I would have to copy all properties from the old object. Is there any shortcut? </p>
<p>Note: I think that serialization it would solve my problem, but this class won't serialize, as discussed in a <a href="https://stackoverflow.com/questions/351265/httpwebrequest-wont-serialize">previous question</a>.</p>
<p><strong>Update</strong> Removed example source code because it was unnecessary</p>
<p><strong>Current view on this matter</strong> There is no shortcut, the only way to redo the request is creating another HttpWebRequest object the same way you created the original one.</p>

411,976 | <p>I am in the early stages of planning and designing a custom accounting application for my firm. My goal is to utilize an open source relational database for the data storage portion and I'm aware of two solid databases that are widely supported: MySQL and PostgreSQL.</p>
<p>For a system that will require transactions, stored procedures, functions, and security, are there any opinions on which of these two databases would be best suited for an accounting application or is there another database I'm missing?</p>
<p>I'm more familiar with MySQL and MS SQLServer 2005, but I'm trying to move away from the latter due to license costs.</p>
<p><em>Let me add: This is not an accounting need like Quickbooks or Peachtree. This is basically a system that handles accounting for a specific business service we provide. There are maybe two or three systems that cater to this need, are priced in the six figure range before any customization, and would require my small firm to be married to a vendor for the long-term. Thus, we are building the application in-house.</em></p>
<p><em>Also, while I appreciate the <strong>Buy vs. Build</strong> argument, I'd like to move away from that particular religious question because the Buy road was already taken and the vendor failed miserably. Sometimes you just need to do the job yourself and this particular project and budget warrants it.</em></p>

411,982 | <p>For my Swing project, I need to support both <strong>Java 5</strong> and <strong>Java 6</strong>.
I have defined a custom <code>JComponent</code> (call it <code>Picture</code>) and, after embedding it in a <code>JScrollPane</code>, I put it in a <code>JPanel</code> that uses DesignGridLayout manager. </p>
<p>DesignGridLayout supports baseline alignment thanks to <strong>swing-layout</strong> open source library (implements baseline support for Java 5 and provides compatibility with the new Java 6 baseline support).</p>
<p>My <code>Picture</code> class <em>overrides</em> <code>public int getBaseline(int width, int height)</code> so that I can define a correct baseline for it. Note that "<em>override</em>" is not completely correct: it overrides the method on Java6 but defines it in Java5.</p>
<p>When I run my sample app <strong>on Java5, everything is fine</strong>: the <code>Picture</code> baseline I have defined is correctly used.</p>
<p>However, <strong>when I use Java6</strong>, my <code>Picture#getBaseline()</code> method does not get called! And of course <strong>the baseline alignment of my picture is terrible</strong> (centered).</p>
<p>After checking in Java6 source, I have seen that, in <code>BasicScrollPaneUI</code>, <code>getBaseline()</code> calls first <code>getBaselineResizeBehavior()</code> on the viewport component (my <code>Picture</code> instance).
And it will call <code>getBaseline()</code> only if <code>getBaselineResizeBehavior()</code> returns <code>Component.BaselineResizeBehavior.CONSTANT_ASCENT</code>.</p>
<p>Now my problem is that <code>getBaselineResizeBehavior()</code> is a Java6 method of <code>JComponent</code> that I cannot implement in Java5 because it returns an enum <code>Component.BaselineResizeBehavior</code> which does not exist in Java5.</p>
<p>So my question (finally) is: how can I implement (or simulate?) <code>getBaselineResizeBehavior()</code> so that my class can still compile and run in a Java5 environment?</p>

412,011 | <p>I have been working on a WCF service library where hopefully all the business logic will end up living. The problem that I am running into is that sometimes I have to make quick fixes to a service and in order to apply those fixes I have to stop the Windows Service, replace the service dll and then restart the Windows service. This is going to start to cause additional headaches as we start migrating more and more of our logic to this layer and have to shutdown the entire service in order to make any changes.</p>
<p>What I would like to do is create an empty shell of a Windows service and dynamically load and unload the services. What is the best way to load and unload .Net DLLs on demand? Or is it better to rely on IIS for this kind of service?</p>

412,019 | <p>I've been profiling an application all day long and, having optimized a couple bits of code, I'm left with this on my todo list. It's the activation function for a neural network, which gets called over a 100 million times. According to dotTrace, it amounts to about 60% of the overall function time.</p>
<p>How would you optimize this?</p>

412,022 | <p>I have a stored procedure in my database that calculates the distance between two lat/long pairs. This stored procedure is called "DistanceBetween". I have a SQL statement allows a user to search for all items in the Items table ordered by the distance to a supplied lat/long coordinate. The SQL statement is as follows:</p>
<pre><code>SELECT Items.*, dbo.DistanceBetween(@lat1, @lat2, Latitude, Longitude) AS Distance
FROM Items
ORDER BY Distance
</code></pre>
<p>How do I go about using this query in NHibernate? The Item class in my domain doesn't have a "Distance" property since there isn't a "Distance" column in my Items table. The "Distance" property really only comes into play when the user is performing this search.</p>

412,070 | <p>Is there a good way, in a javascript onfocus() handler, to trampoline the focus to the next item in the tab order, without having to manually enter the ID of the item that should be next?</p>
<p>I built an HTML date picker in Django/jQuery. It's a line edit followed by a calendar icon that pops up a calendar. I want to be able to tab from the line edit to the next input, skipping the link for the calendar icon. I mean for it to be a generalized widget, so I can't hardcode the id of whatever is next and call .focus(). I know I could set tabindex attributes on everything, but that's more manual than I'd like. Also, iirc, that wouldn't prevent it from taking the focus, it would just put it at the end of the tab order.</p>

412,101 | <p>Let's say I have a table <em>tbl</em> with columns <em>id</em> and <em>title</em>.
I need to change all values of title column:</p>
<ol>
<li>from 'a-1' to 'a1',</li>
<li>from 'a.1' to 'a1',</li>
<li>from 'b-1' to 'b1',</li>
<li>from 'b.1' to 'b1'.</li>
</ol>
<p>Right now, I'm performing two UPDATE statements:</p>
<pre><code>UPDATE tbl SET title='a1' WHERE title IN ('a-1', 'a.1')
UPDATE tbl SET title='b1' WHERE title IN ('b-1', 'b.1')
</code></pre>
<p>This isn't at all a problem, if the table is small, and the single statement completes in less than a second and you only need a few statements to execute.</p>
<p>You probably guested it - I have a huge table to deal with (one statement completes in about 90 seconds), and I have a huge number of updates to perform.</p>
<p>So, is it possible to merge the updates so it would only scan the table once? Or perhaps, there's a better way to deal with in a situation like this.</p>
<p>EDIT: Note, that the real data I'm working with and the changes to the data I have to perform are not really that simple - the strings are longer and they don't follow any pattern (it is user data, so no assumptions can be made - it can be anything).</p>

412,103 | <p>For the purposes of unit testing I'd like to create an iPhone project target in Xcode that includes all of the release application files, plus some additional files containing code useful for UI unit testing.</p>
<p>I can do this by duplicating the original application target; however, the problem with this is that every time I add a new source file to the app target, I need to also add it to the UnitTestUI target. It's not a big deal, just inconvenient to always remember to add files to both targets. </p>
<p>Is there some way to set up a dependency so that every file added to the original app target is also auto added the unit test target?</p>

<li><p>How would I use 'Type' with it, as far as I know there is no 'Type' in C++.</p></li>

<p>and I got message from g++, says <code>invalid use of non-static member function</code>.</p>
<p>How do I get pointer to member function of instance?</p>
<p><strong>Edit</strong>:My original problem is about Win32 API.</p>
<p>I'm forced to write windows program with old Win32 API at school. but I don't want to write horrible switch statement like some example codes on text. Then, I decided to write wrapper in C++.</p>
<p>I want to write the window class like ... </p>
<pre><code>class Window {
public:
LRESULT update (HWND, UINT, WPARAM, LPARAM);
void run();
// below methods are called by update()
virtual void onclick(int, int);
virtual void ondraw(); // ... and more methods
};
</code></pre>
<p>and I'm willing to write my application class with deriving this class and overloading some methods.</p>
<p>Finally, my actual probrem is how to do this in C++.</p>
<pre><code> // on initializing my window object,
// I must register window class with callback which is
// not a C++ function object.
// I try to explain what I want to do with psudocode mixing C++ and javascript.
WNDCLASS wndclass;
Window *self = this;
wndclass.lpfnWndProc = function () {
return self.update.apply(self, argunemts);
};
</code></pre>
<p>In other word, I have to make closure into function pointer. I don't know how to do this, but I can't believe this can't do in C++.</p>
<p><strong>Edit</strong>: The original title of this question was <em>How to get pointer-to-member-function of instance</em>. But this title and my question didn't tell my actual problem enough. Sorry to early answerers, and litb, thank you for suggestion and very useful answer!</p>

412,184 | <p>Back in the ITAR era, there was a <a href="http://www.cypherspace.org/adam/rsa/perl-dh.html" rel="nofollow noreferrer">popular sig that performed Diffie-Hellman key exchange</a>:</p>

<p>I dug around in the SharePoint logs, and at the time the page is loaded, I see the following error in ULS:</p>
<p>Control template "MediaPlayerFieldControl" does not exist.</p>
<p>If you've implemented this control, did you have to implement anything other than what the article details? Pretty sure I don't need an ASCX here because the control is handling rendering the media player. </p>

There are a lot of great resources out there, but one of the issues I'm running into conceptually is how to organize a flex project. Coming from the standpoint of a "traditional" ASP.NET web application I'd create folders of related pages, controls, CSS, JavaScript, etc. </p>
<p>What's the best pattern for organizing a flex application? I like using the code behind pattern with my MXML files, but these aren't really "pages" per se, so how do you keep from just dumping everything into the root of your src folder?</p>

412,227 | <p>You always hear that functional code is inherently easier to parallelize than non-functional code, so I decided to write a function which does the following:</p>
<p>Given a input of strings, total up the number of unique characters for each string. So, given the input <code>[ "aaaaa"; "bbb"; "ccccccc"; "abbbc" ]</code>, our method will returns <code>a: 6; b: 6; c: 8</code>.</p>
<p>Here's what I've written:</p>
<pre><code>(* seq<#seq<char>> -> Map<char,int> *)
let wordFrequency input =
input
|> Seq.fold (fun acc text ->
(* This inner loop can be processed on its own thread *)
text
|> Seq.choose (fun char -> if Char.IsLetter char then Some(char) else None)
|> Seq.fold (fun (acc : Map<_,_>) item ->
match acc.TryFind(item) with
| Some(count) -> acc.Add(item, count + 1)
| None -> acc.Add(item, 1))
acc
) Map.empty
</code></pre>
<p>This code is ideally parallelizable, because each string in <code>input</code> can be processed on its own thread. Its not as straightforward as it looks since the innerloop adds items to a Map shared between all of the inputs.</p>
<p>I'd like the inner loop factored out into its own thread, and I don't want to use any mutable state. <b>How would I re-write this function using an Async workflow?</b></p>

<p>something similar to the following;</p>
<pre><code>public class UserRepository : IUserRepository
{
public IQueryable<User> GetUsers()
{
// do stuff
}
}
public class UserService
{
public IList<User> GetUserById

var rep = new UserRepository();
var users = rep.GetUsers();

412,300 | <p>Smashed my head against this a bit too long. How do I prevent a user from browsing a site's pages after they have been logged out using FormsAuthentication.SignOut? I would expect this to do it:</p>
<pre><code>FormsAuthentication.SignOut();
Session.Abandon();
FormsAuthentication.RedirectToLoginPage();
</code></pre>
<p>But it doesn't. If I type in a URL directly, I can still browse to the page. I haven't used roll-your-own security in a while so I forget why this doesn't work.</p>

412,305 | <p>If I create a TcpChannel using port zero i.e. allowing .Net Remoting to allocate an available port, is there anyway to then determine which port number has been allocated? </p>
<p>I know that I can specify the port number when creating the channel, however I don't want to do this as I want to run multiple instances of the listening application on the same Citrix server - each instance listening on a different port. </p>
<p>Ideally I don't want to have to go to the trouble of reserving a bunch of ports and then keeping track of which ones have been allocated. I'd just like to let the port be allocated automatically - but then I need to be able to know which port number has been allocated.</p>

412,314 | <p>I'm trying to find out the best practices for real-world application development. I'm having trouble understanding how to properly configure third-party libraries for deployment as a standalone package. It seems that ASDF-INSTALL and ASDF are intended to install libraries to either home or site, changing the state of the development platform. That's fine if I were developing a server side application and I wanted to administer these dependencies for the entire CL installation on the box.</p>
<p>But what if I wanted to create a standalone application, deployed via install scripts, and running alone in its own CL instance? I would want to avoid changing the CL instance or target system configuration for any other applications (i.e. overwrite other copies of libraries that other applications depend on). In Java, all I have to do is create an include directory that contains those libraries and set my CLASSPATH. How do I get the same level of isolation in CL, assuming that I don't install my own CL runtime, and instead use what's on the system?</p>
<p>It occurs to me that this is a common issue with all dynamically compiled/interpreted languages, since the runtime will have a lifetime longer than any particular application that the runtime runs (i.e. Ruby or Python), and applications will share the same library load state. I don't have any experiences with such languages, so the best practice is probably staring me in the face.</p>
<p>IDK if this would be implementation specific, but I am running Clozure CL.</p>
<p>EDIT:</p>
<p>Ramarren:</p>
<p>I'll check out Mudballs. Thank you.</p>
<p>Installing libraries is the opposite of what I want, since installing implies modifying the host system state. I think the key must be in your last paragraph. How do you create the startup script to set <em>central-registry</em> to an isolated directory? Is it possible to use ASDF-INSTALL to fetch stuff into said directory? And how do you bootstrap the whole thing if the base image of your CL implementation doesn't include ASDF (Clozure has ASDF by default, but how would CLISP do it)?</p>
<p>I'm thinking in terms of a dev team too. After I create a new CL project stub and do that initial commit to CVS or SVN, how do other devs check it out to their local environment and work with it? Even assuming that everyone has ASDF in their profile/site startup, other devs may have a different set of libs in their <em>central-registry</em>. We shouldn't have to sync up just to work on a project together. There's got to be a clean way to launch an project specific instance of the CL runtime from Emacs/SLIME and load exactly what's specified in the project, no more, no less.</p>
<p>If there's any best practice resources online, in CL or any other language, I'll be glad to roll my own solution and open source it.</p>
<p>Luis:</p>
<p>SAVE-APPLICATION is good for deployment, but not for the multiple-dev project stub I outlined.</p>
<p>EDIT 2:</p>
<p>vatine:</p>
<p>Version dependency is precisely why this is a problem. If I were developing a Perl or Ruby web app, then I can depend on the existence of a webadmin to manage these dependencies. Developing apps for retail or for small-to-mid-size businesses where Lisp is alien technology (and I cannot convince them to "skill up" their IT org to admin it), that approach is unacceptable.</p>
<p>I was able last night to kind of get what I want by creating a project-level .lisp file that loads its own project-specific ASDF instance, set a project-local <em>central-registry</em>, and manually downloading dependent libs (without ASDF-INSTALL, which was a painful cascade of dependencies for just CLSQL and Weblocks). It still isn't ideal from a dev tools standpoint, since I had to remove all customization from my home and site for both SLIME and Clozure itself. Also, shared dependencies aren't resolved either (CLSQL and Weblocks both use MD5).</p>
<p>Java has class loader isolation, which is how it solves the version dependency issue. Then there's the separate issue of how to get the libs you want into the project (a la Maven). The former is a core language issue; the latter has to do with tools. I'm going to hack together a SLIME extension that does what ASDF-INSTALL does to a project include directory (a la Maven), and modifies lib source code to intercept defpackage calls to somehow prepend a gensym string to enforce isolation. There's plenty of holes in this approach, I know, and I don't know enough about the package spec to know how deep I can bury this.</p>
<p>I don't know anything about Python, but I do know that retail-level apps exist; I use MusicBrainz Picard all the time. I'll look into how Python does it.</p>

412,319 | <p>I'm using the built-in system class for sending emails in .NET. It's in System.Mail namespace or something like that.</p>
<p>I need to add an interface to this class so I can swap it out for testing or another implementation.</p>
<p>To do this, I just define a class that wraps this built-in class?</p>
<p>Is this an example of the decorator pattern? I'm just a bit confused because the description of the decorator pattern usually states that it is used to add functionality, and I won't be adding any.</p>

412,344 | <p>I know downcasting like this won't work. I need a method that WILL work. Here's my problem: I've got several different derived classes all from a base class. My first try was to make an array of base class. The program has to select (more or less at random) different derived classes. I had tried casting from a base class to the derived class, putting it in the array of the base, but obviously that didn't work. I was sincerely hoping for another method than simply sticking arrays of all the derived classes, because there could be quite a few derived classes. Is there any better way to do this that I'm just brainfarting on? </p>
<p>If y'all need code examples or more information, just let me know. It all makes sense to me, but It's late and it may not make sense to everybody else heh. </p>
<p>Any help is very much appreciated, guys.</p>

412,345 | <p>Are there any lint tools available for actionscript? One source would be ideal, but anything is welcome.</p>

412,378 | <p>I come from a C++ background where I can use template mixins to write code that refers to FinalClass which is a template parameter that is passed in. This allows reusable functions to be "mixed-in" to any derived class, by simply inheriting from ReusableMixin with a template paramter of MyFinalClass. This all gets inlined into the class so it's as though I just wrote a big class that did everything -- ie very fast! Since mixins can chain, I can mix-in all sorts of behaviour (and state) into one object.</p>
<p>If anyone wants clarification on the technique, please ask. My question is, how can I get reuse like that in C#? Note: C# generics don't allow inheriting from a generic parameter.</p>

412,409 | <p>I wonder if it is a good practice to use JUnit's @Ignore. And how people are using it? </p>
<p>I came up with the following use case: Let's say I am developing a class and writing a JUnit test for it, which doesn't pass, because I'm not quite done with the class. Is it a good practice to mark it with @Ignore? </p>
<p>I'm a little concerned that we might miss the ignored test case later on or that people start using it to "force" tests to pass CI.</p>

412,410 | <p>I'm trying to compile GNUstep on a linux box but gnustep-gui-0.16.0 package is failing. I downloaded GNUstep Startup stable 0.20.1 (<a href="http://wwwmain.gnustep.org/resources/downloads.php" rel="nofollow noreferrer">http://wwwmain.gnustep.org/resources/downloads.php</a>)and follow instructions about how to compile (./configure && make). I'm getting this error:</p>
<p><code>libgnustep-gui.so: undefined reference to 'png_sizeof'</code></p>
<p>I have compiled latest libpng (1.2.34) and I can see that png_sizeof is defined as macro. However, I'm not quite sure how to fix the gnustep-gui-0.16.0 build. I tried to pass the include/lib directory where libpng is installed to configure build but nothing seems to help.</p>
<p>I have quite up to date linux box but using gcc 3.3 (upgrade is not an option - but this should not be a problem).</p>
<p>Full error:</p>

412,412 | <p>I'm using the MVC beta to write a simple application to understand ASP.Net MVC. The application is a simple photo/video sharing site with tagging. I'm working off the MVC skeleton project. I added some Html.ActionLink()'s to the navigation bar, but I'm having a problem with one of the Html.ActionLink()'s that I added in one spot. </p>
<p>I want ~/Tags to show all tags from the database and I want ~/Tags/{tag} to show a listing of all the files that are tagged with {tag}. This works as expected, but when I follow a ~/Tags/{tag}, it changes the Html.ActionLink() in the navigation bar to be the same as the ~/Tags/{tag} link instead of just pointing to ~/Tags. I'm not understanding why the ActionLink() in my navigation bar is changing when I follow the ~/Tags/{tag}. If I navigate to a different link in the project, the ActionLink() works as expected.</p>
<p>I have the actionlink and route set up like this. My TagsController has this Index action. The int? is for a paging control. I have two Views, one called All and one called Details. What am I doing wrong?</p>
<pre><code> Html.ActionLink("Tags", "Index", "Tags") // In navigation bar
routes.MapRoute(
"Tags",
"Tags/{tag}",
new
{
controller = "Tags", action = "Index", tag = "",
});
public ActionResult Index(string tag, int? id )
{ // short pseudocode
If (tag == "")
return View("All", model)
else
return View("Details", model)
}

412,438 | <p>Is there a way to undefine the += on strings and wstrings for chars and wchar_t?</p>
<p>Basically I want to avoid bugs like the following:</p>
<pre><code>int age = 27;
std::wstring str = std::wstring(L"User's age is: ");
str += age;
std::string str2 = std::string("User's age is: ");
str2 += age;
</code></pre>
<p>The above code will add the ascii character 27 to the string instead of the number 27.</p>
<p><strong>I obviously know how to fix this, but my question is: how do I produce a compiler error in this situation?</strong></p>
<p>Note: You can override += on std::string and int to properly format the string, but this is not what I want to do. I want to completely disallow this operator on these operands. </p>

412,440 | <p>What are the best practices for implementing temporary transaction password feature for website?</p>
<p>For e.g in banking/finance scenarios like
- While transfering funds from one account to another, a transaction password is required
- While commiting a trade, a transaction password is required
- etc.</p>
<p>The password should be temporary and time based i.e. this password should not work after x minutes has elapsed.</p>
<p>What algorithm would you recommend?
Do you suggest keeping track of used passwords i.e. store used password in some store?</p>
<p>Some website use a OneTimePassword device. Apart from this please feel to highlight any other strategy you think may be appropriate.</p>
<p>Any other thoughts/suggestions/algorithm welcome.</p>
<p>Edit: Based on question from 'lassevk'</p>
<ol>
<li>The password would be communicated by email/phone/sms.</li>
<li>There is no third site involved.</li>
</ol>
<p>I require this for additional level of security for critical points in the application.
This may also be called as "AuthenticationCode". </p>

<p>To return the response in REST format, send a parameter "format" in the request with a value of "rest". When using the REST request method, the response defaults to REST.</p>
<p>A method call returns this:</p>
<p>
[xml-payload-here]
</p>
<p>If an error occurs, the following is returned:</p>

412,459 | <p>I've got some data manipulation code which spits out csv at the end.</p>
<p>I started upgrading it to add units of measure everywhere, but I now have a problem with my csv function:</p>
<pre><code>val WriteCSV : string -> 'a list array -> 'b list -> string -> unit
</code></pre>
<p>(the parameters are fileName, column array, column headers, separator)</p>
<p>Where I previously sent [|s;x;y|] to WriteCSV, I now have a problem, because I can't send [|skm; xmm; ymm|].</p>
<p>I tried writing a function for generically removing units of measure, but it doesn't work.</p>
<pre><code>let removeUnit (n:float<_>) = n/1.0<_>
</code></pre>
<p>My questions are:</p>
<ul>
<li>Why doesn't it work? </li>
<li>Can it be made to work?</li>
<li>Is there another way to solve this particular problem?</li>
</ul>

412,472 | <p>I have code that looks like this:</p>
<pre><code>import xmlrpclib
class Base(object):
def __init__(self, server):
self.conn = xmlrpclib.ServerProxy(server)
def foo(self):
return self.conn.do_something()
class Derived(Base):
def foo(self):
if Base.foo():
return self.conn.do_something_else()
</code></pre>
<p>How should I use mocking to test the behavior of the <code>Derived</code> class? I don't want to assume that whatever the XML-RPC connection talks to will actually exist, but I feel like mocking the <code>xmlrpclib</code> module requires too much knowledge of the implementation of the <code>Base</code> class (which I have other tests for).</p>
<p>Or, I guess, should I even use mocking to test this? If not, how would you test it?</p>

412,498 | <p>In my Apache webserver I put this:</p>
<pre><code><Directory /var/www/MYDOMAIN.com/htdocs>
SetHandler mod_python
PythonHandler mod_python.publisher
PythonDebug On
</Directory>
</code></pre>
<p>Then I have a handler.py file with an index function.</p>
<p>When I go to MYDOMAIN.com/handler.py, I see a web page produced by the index function (just a plain vanilla HTML page). Every other page is of this type: MYDOMAIN.com/handler.py/<em>somename</em> where <em>somename</em> corresponds to a funcion in handler.py file.</p>
<p>But when I go to MYDOMAIN.com, I get this:</p>
<blockquote>
<p>Not Found</p>
<p>The requested URL / was not found on
this server.</p>
</blockquote>
<p>Is theres a way with mod_python and publisher to just use the root and not a name.py as a starting point?</p>
<p>I already tried with this in the apache conf file:</p>
<blockquote>
<p>DirectoryIndex handler.py</p>
</blockquote>
<p>To no avail :(</p>
