372,807 | <p>I have a problem with a bash script. I have to use the operator * to multiplicate. Instead the script bugs me with expansion and using as operator the name of the script itself. I tried with single quotes but it doesn't work :( Here's the code</p>

372,808 | <p>I have uploaded some files to a directory under public and I try to access them using Dir.glob. But I get no results back. </p>
<p>The Dir.glob works fine on dev server (mongrel) and also works fine when using script/console on the site installed on site5</p>
<p>is there a way to get this working or a different way to get the list of files?</p>

372,820 | <p>I'm looking at this control, and it seems to be lacking the standard .net "datasource" and "datamember" properties for databinding. Is this control not bindable? I can write some custom function that populates the treeview from a given data source, I suppose, and embed data objects as necessary, but is that the 'best practice'? Or does everyone simply use a 3rd party treeview control? </p>

372,834 | <p>I am trying to create a SQL server login and database user from within my application, along with a custom application user row. I want these users to be able to create other users - i.e. the application will control who can/can't create users but I need all users to have permissions for creating SQL server logins and database users.</p>
<p>I have got the server login permissions working - i.e. an existing user/login can create a new login - by adding the logins to the 'securityadmin' server role - which grants the 'ALTER ANY LOGIN' privilege. </p>
<p>I tried to do the same with the database users - adding them to the 'db_accessadmin' database role - which supposedly grants the ALTER ANY USER privilege, which is required for CREATE USER. </p>
<p>However any time I try to create a new database user using a user with the above privileges I get a permissions exception.</p>
<p>I have tried manually granting the ALTER ANY USER permission to a particular user (GRANT ALTER ANY USER TO demouser) but this doesn't work either.</p>

372,862 | <p>I'm an old (but not too old) Java programmer, that decided to learn C++. But I have seen that much of C++ programming style, is... well, just damn ugly!</p>
<p>All that stuff of putting the class definition in a header file, and the methods in a different source file- Calling functions out of nowhere, instead of using methods <strong>inside classes</strong>. All that just seems... wrong!</p>
<p>So finally, is there any reason for me to continue with this massacre to the OOP, and anything that is good and righteous in programming, or can I just ignore that old-fashioned C++ conventions, and use my good Java programing style?</p>
<p>By the way I'm learning C++, because I want to do game programing.</p>
<p>Here is an example:</p>
<p>In an C++ website I found a Windows implementation:</p>
<pre><code>class WinClass
{
public:
WinClass (WNDPROC wndProc, char const * className, HINSTANCE hInst);
void Register ()
{
::RegisterClass (&_class);
}
private:
WNDCLASS _class;
};
</code></pre>
<p>That class is located in a header file and the constructor:</p>
<pre><code>WinClass::WinClass (WNDPROC wndProc, char const * className, HINSTANCE hInst)
{
_class.style = 0;
_class.lpfnWndProc = wndProc; // Window Procedure: mandatory
_class.cbClsExtra = 0;
_class.cbWndExtra = 0;
_class.hInstance = hInst; // Owner of the class: mandatory
_class.hIcon = 0;
_class.hCursor = ::LoadCursor (0, IDC_ARROW); // Optional
_class.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1); // Optional
_class.lpszMenuName = 0;
_class.lpszClassName = className; // Mandatory
}
</code></pre>
<p>Is located at a .cpp source file.</p>
<p>What I could just do is:</p>
<pre><code>class WinClass
{
public:
WinClass (WNDPROC wndProc, char const * className, HINSTANCE hInst)
{
_class.style = 0;
_class.lpfnWndProc = wndProc; // Window Procedure: mandatory
_class.cbClsExtra = 0;
_class.cbWndExtra = 0;
_class.hInstance = hInst; // Owner of the class: mandatory
_class.hIcon = 0;
_class.hCursor = ::LoadCursor (0, IDC_ARROW); // Optional
_class.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1); // Optional
_class.lpszMenuName = 0;
_class.lpszClassName = className; // Mandatory
}
void Register ()
{
::RegisterClass (&_class);
}
private:
WNDCLASS _class;
};
</code></pre>
<p>And now the constructor is inside its class.</p>

372,877 | <p>I have Default.aspx page, which inherits from BasePage.cs, which inherits from System.Web.UI.Page. BasePage is where I do some common things every page must do upon loading.</p>
<p>In BasePage, lets say I'm checking for X. If X=1, then I will redirect to my "Discontinued.aspx" page immediately and stop execution of BasePage. If I find X=1, I say:</p>
<p>HttpContext.Current.Response.Redirect("Discontinued.aspx", true);</p>
<p>I want the redirect to stop execution of BasePage and immediately jump out - hence the "true" in the above statement - which should stop execution of the current page as I understand. The problem is, it doesn't. I'm expecting the redirect to throw the "thread abort exception". </p>
<p>When I run in debug mode, it contines stepping through as though it didn't just redirect and leave. </p>
<p>But the redirect was still started as well - once I get done stepping through the rest of BasePage, the "Discontinued" page then begins to load as a result of the redirect. </p>
<p>Is there a reason my Redirect will not kill execution of BasePage?</p>

372,915 | <p>I'm dealing with game dialogue files (conversation between player and non-playable-characters) where dialogue choices and their outcome depend on certain conditions and result in certain actions. Now, I could write a simple parser to handle some sort of language for specifying the pre and post-conditions, but a friend of mine suggested using XML. Conditions could be stored as attributes of a dialogue element and choices and actions are inner elements. I'd then use an eval function to parse these conditions and statements (I'm using Ruby to make this game). To make such an approach simpler, I could then write a simple GUI to manipulate these files without worrying about ugly XML. </p>
<p>But it strikes me as an odd choice to handle logic in XML files. My understanding is that XML files are for the storage and exchange of data, and I always read rants about how people overuse XML for all sorts of things it wasn't designed for. My friends responds by noting how XML IS used for everything, including XHTML and <a href="http://www.asahi-net.or.jp/~cs8k-cyu/bulletml/index_e.html" rel="noreferrer">this bullet description language</a> (which also illustrates some logic). </p>
<p>To be honest, using XML would simplify a lot of things for me. Writing a parser can be painful and time consuming, and my requirements are generally simple. But is it really okay or would I regret such a choice later?</p>
<p>For people interested in details, here's what a basic dialogue exchange might look like in an XML file:</p>
<pre><code><dialogue id="101" condition="!npc.carsFixed">
<message>Man, fix my car!</message>
<choices>
<choice condition="hero.carFixingSkill > 5" priority="7" id="Sure!">
<command>hero.carFixingSkills += 1</command>
<command>npc.carFixed = true</command>
<command>hero.playSmokeAnimation()</command>
<command>nextDialogue = 104</command>
</choice>
<choice condition="hero.carFixingSkill <= 5" id="I can't...">
<command>nextDialogue = 105</command>
</choice>
<choice id="Fix it yourself">
<command>npc.likesHero -= 1</command>
</choice>
</choices>
</dialogue>
</code></pre>
<p>The corresponding code if written in Ruby would be:</p>
<pre><code>def dialogue101
if !npc.carsFixed
showMessage("Man, fix my car!")
choices = []
if hero.carFixingSkill > 5
choices.push(Choice.new("Sure!", 7))
else
choices.push(Choice.new("I can't"))
end
choices.push(Choice.new("Fix it yourself"))
choices = selectTopPriority(choices) if choices.size > 4
result = showChoices(choices)
case result
when "Sure"
hero.carFixingSkills += 1
npc.carFixed = true
hero.playSmokeAnimation
dialogue104
when "I can't"
dialogue105
when "Fix it yourself"
npc.likesHero -= 1
end
end
end
</code></pre>
<p>Stuff like likesHero and carFixingSkills are knowledge pieces player and NPCs can have, which would probably be stored in a hash in the real implementation. I find the dialogue file approach more flexible because I could make an editor to easily edit dialogue and conditions/actions, and because of the complex nature of game conversation trees. A scripting language like Ruby or Lua helps, but it'll require complex structures to handle to logic of such trees. </p>
<p>Back to the original question, is XML the right tool for the job or am I missing something?</p>

372,916 | <p>OK,</p>
<p>This question has probably been answered before, but I'm not sure of how to word the Title.</p>
<p>I have a class that has methods which return many composite LINQ queries. Most of these queries form Anonymous Types in order to get the data I need. I found out that I'm not able to return an Anonymous Type from a method, so I've been creating sub classes and populating them in the "select new" part of the query.</p>
<p>Is there a better way of doing this? All of these methods return an IEnumerable of some kind and I really want to keep things extracted.</p>
<p>Thanks!</p>

372,933 | <p>I am taking in a string from user input, and splitting it on whitespace (using \w) into an array of strings. I then loop through the array, and append a part of the where clause like this:</p>
<pre><code> query += " AND ( "
+ "field1 LIKE '%" + searchStrings[i] +"%' "
+ " OR field2 LIKE '%" + searchStrings[i] +"%' "
+ " OR field3 LIKE '%" + searchStrings[i] +"%' "
+ ") ";
</code></pre>
<p>I feel like this is dangerous, since I am appending user input to my query. However, I know that there isn't any whitespace in any of the search strings, since I split the initial input on whitespace.</p>
<p>Is it possible to attack this via a SQL injection? Giving <code>Robert');DROP TABLE students;--</code> wouldn't actually drop anything, since there needs to be whitespace in there. In that example, it would not behave properly, but no damage would be done.</p>
<p>Can anyone with more experience fighting SQL injections help me either fix this, or put my mind at ease?</p>
<p>Thanks!</p>
<p><strong>EDIT:</strong></p>
<p>Wow, that is a lot of great input. Thank you everyone who responded. I will investigate full-text search and, at a minimum, parameterize my query.</p>
<p>Just so I can better understand the problem, would it be possible to inject if all whitespace <strong>AND</strong> single quotes were escaped?</p>

372,934 | <p>By "fixed vector" I mean a static list of values, like 1 through 24.</p>
<p>The current query looks like this (simplified)</p>
<pre><code>SELECT Period, Profit FROM Projections
</code></pre>
<p>But the data is "sparse" — so there's not a row for every period.</p>
<p>What query will give me a row for peiods 1-24 every time, with zeros (or NULLs) where there's no data? </p>
<p>I would like to do this with just the query to avoid a mess of client code.</p>

372,955 | <p>If I'm rendering a regular view in asp.net mvc the only domain object properties that show up in my page the ones I specifically write out. For example:</p>
<pre><code><div><%= Customer.FirstName %></div>
</code></pre>
<p>However, if I serialize a domain object for json it will include every property. Example:</p>
<pre><code>public JsonResult Customer (int? id)
{
Customer customer = _serviceLayer.GetCustomer (id.Value);
return Json (customer);
}
</code></pre>
<p>Since I don't want every Customer property exposed what is the best way to filter the output properties for json in this case? Can you use an include/exclude list like UpdateModel()? Use a proxy class such as public class JsonCustomer? What would you recommend?</p>

372,974 | <p>I want to programmatically invoke an event handler for a control. For example:</p>
<pre><code>DateTimePicker dtpLastConsummated;
</code></pre>
<p>I want to trigger the TextChanged event handler for the <code>dtpLastConsummated</code>, how can i do it?</p>
<p>In other languages I would call something akin to:</p>
<pre><code>dtpLastConsummated.TextChanged(this, new EventArgs());
</code></pre>
<p>but in .NET you can have multiple event handlers:</p>
<pre><code>dtpLastConsummated.Click +=new EventHandler(dtpLastConsummated_TextChanged);
dtpLastConsummated.Click +=new EventHandler(dtpLastConsummated_AnotherHandler);
dtpLastConsummated.Click +=new EventHandler(dtpLastConsummated_MoreHandlers);
...
dtpLastConsummated.Click +=new EventHandler(dtpLastConsummated_Nminus1);
</code></pre>
<p>so you need a way to trigger all the attached event handlers.</p>
<hr>
<h2>Answer</h2>
<p>The following code will fire the event:</p>
<pre><code>Toolkit.FireEvent(dtpLastConsummated, "TextChanged", new EventArgs());
</code></pre>
<p>And here's the code of the static toolkit function:</p>
<pre><code>/// <summary>
/// Programatically fire an event handler of an object
/// </summary>
/// <param name="targetObject"></param>
/// <param name="eventName"></param>
/// <param name="e"></param>
public static void FireEvent(Object targetObject, string eventName, EventArgs e)
{
/*
* By convention event handlers are internally called by a protected
* method called OnEventName
* e.g.
* public event TextChanged
* is triggered by
* protected void OnTextChanged
*
* If the object didn't create an OnXxxx protected method,
* then you're screwed. But your alternative was over override
* the method and call it - so you'd be screwed the other way too.
*/
//Event thrower method name //e.g. OnTextChanged
String methodName = "On" + eventName;
MethodInfo mi = targetObject.GetType().GetMethod(
methodName,
BindingFlags.Instance | BindingFlags.NonPublic);
if (mi == null)
throw new ArgumentException("Cannot find event thrower named "+methodName);
mi.Invoke(targetObject, new object[] { e });
}
</code></pre>
<hr>
<p><strong>Note:</strong> I'm not creating a subclass of every control in the .NET framework, and every 3rd party control, and convincing an enterprise worth of developers to retrofit every form to use my custom controls.</p>

372,982 | <p>I have from the backend a time on the format 00:12:54 and I display it to the screen. But, I would like to have this time to continue to go down. I have though to create a variable in javascript that will old the time and with <code>setTimeout</code> to loop to display with document.getElementById the new value. I think it can be problematic if I have many time to go down in same time. I might require an array?</p>
<p>How would you do that? If I have no other suggestion, I will try my way, but I am curious to know if it does have a more secure way to do it.</p>

372,988 | <p>I'm new to database indexing, if I have 2 columns in a table that are good choices for indexing like for example,</p>
<pre><code>[Posts](
[PostID] [int] IDENTITY(1,1) NOT NULL,
[UserName] [nvarchar](64) NOT NULL,
[ApplicationType] [smallint] NOT NULL,
...
)
</code></pre>
<p>in this case PostID would be the PRIMARY KEY CLUSTERED index, then I want to do more indexing since it's a large table and I want to do on UserName and ApplicationType, now should I index each individually (one on UserName, one on ApplicationType) or index them as a whole (one index on UserName, ApplicationType together)? Is there a limit to the number of indexes I can have before making it bad practice? What generally is the rule of thumb on this?</p>
<p>Thanks,</p>

373,012 | <p>I am trying to create a simple dialog in MFC using Visual C++. My problem is that when I get the dialog on the screen and try to type in an Edit Box field, if I type the letter 'a' once, it appears in the edit box as 'aaaaaaaaaaa' (that's 12 a's). Furthermore, if I try to navigate around in the box using the arrow keys, the carat moves 12 characters at a time.</p>
<p>It's not just a display error, as the output from the editbox is still "aaaaaaaaaaaa".</p>
<p>I'd post code, but there's really none to post. I added the edit box using the Toolbox in Visual Studio and assigned a variable to it in my class so this isn't any sort of special edit box.</p>
<p>If anyone has any thoughts as to what might be happening it would be greatly appreciated. Unfortunately, I don't know where to begin.</p>

373,017 | <p>Which techniqes would you use to implement a search for contents in a column on a very big table in MySql? Say for instance that you have 10.000.000 emails stored in a table in the database and would like to implement a subject search, that would enable me to search for one or more words that was present in the email subject. If the user searched for "christmas santa" you should find a emails with subjects like "Santa visits us this christmas" and "christmas, will santa ever show".</p>
<p>My idea is to process all the words in the subjects (strip all numbers, special signs, commas etc) and save each word in an index table, where I have a unique index on the word column. Then I would link that to the email table by a many to many relationship table.</p>
<p>Is there a better way to perform wildcard searches on very big tables ?</p>
<p>Is there databases that natively supports this kind of searches ?</p>

<code>'CHECK_CONSTRAINTS'</code> bulk hints are not

<p>I read some documentation and created the bulk copy object with the constructor that lets me specify such things:</p>
<pre><code> SqlBulkCopy bc = new SqlBulkCopy(
System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"],
SqlBulkCopyOptions.FireTriggers & SqlBulkCopyOptions.CheckConstraints);

<p>But this doesn't change anything - I get the same error message as before. I tried fiddling with some of the other SqlBulkCopyOptions values but no luck. I really thought this would fix the problem, am I missing something?</p>
<p>I tested the procedure after granting ALTER on the table to my user, and the operation succeeded. However this is not an option for my situation.</p>

373,064 | <p>My goal is to make sure that in most scenarios objects are used via a "read-only interface" that is a subset of the full interface.</p>
<ul>
<li>As an example, if I were using C++, I would just return a <code>const</code> object.</li>
<li>In C#, if I could achieve this with interfaces, I would just implement a read-only interface and use it everywhere. However, I need operator overloading, which is not allowed for interfaces. That's why I have to use an abstract base class.</li>
<li>But if I define an abstract base class, I am not allowed to change accessibility in the derived type.</li>
</ul>
<p>So, how can I achieve my goal in C#?</p>

373,067 | <p>I'm creating a simple API that creates typed classes based on JSON data that has a mandatory 'type' field defined in it. It uses this string to define a new type, add the fields in the JSON object, instantiate it, and then populate the fields on the instance.</p>
<p>What I want to be able to do is allow for these types to be optionally pre-defined in whatever application is using my module. This is so methods and other application-specific attributes not found in the JSON object can be added. I'd like to have my module check if a type already exists, and if it does, use that instead of dynamically creating the type. It would still add attributes from the JSON object, but it would be recycling the existing type.</p>
<p>My JSON data is:</p>
<pre><code>{
"type": "Person",
"firstName": "John",
"lastName": "Smith",
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": 10021
},
"phoneNumbers": [
"212 555-1234",
"646 555-4567"
]
}
</code></pre>
<p>My code so far (assume json_object is a dict at this point):</p>
<pre><code>if not json_object.has_key('type'):
raise TypeError('JSON stream is missing a "type" attribute.')
##### THIS IS WHERE I WANT TO CHECK IF THE TYPE BY THAT NAME EXISTS ALREADY ####
# create a type definition and add attributes to it
definition = type(json_object['type'], (object,), {})
for key in json_object.keys():
setattr(definition, key, None)
# instantiate and populate a test object
tester = definition()
for key, value in json_object.iteritems():
setattr(tester, key, value)
</code></pre>

373,084 | <p>Address records are probably used in most database, but I've seen a number of slightly different sets of fields used to store them. The number of fields seems to vary from 3-7, and sometimes all fields are simple labelled address1..addressN, other times given specific meaning (town, city, etc).</p>
<p>This is UK specific, though I'm open to comments about the rest of the world too. Here you need the first line of the address (actually just the number) and the post code to identify the address - everything else is mostly an added bonus.</p>
<p>I'm currently favouring:</p>
<ul>
<li>Address 1</li>
<li>Address 2</li>
<li>Address 3</li>
<li>Town</li>
<li>County</li>
<li>Post Code</li>
</ul>
<p>We could add Country if we ever needed it (unlikely).</p>
<p>What do you think? Is this too little, too much?</p>

373,126 | <p>I am trying to so something like <a href="https://stackoverflow.com/questions/48475/database-design-for-tagging">Database Design for Tagging</a>, except each of my tags are grouped into categories.</p>
<p>For example, let's say I have a database about vehicles. Let's say we actually don't know very much about vehicles, so we can't specify the columns all vehicles will have. Therefore we shall "tag" vehicles with information.</p>
<pre><code>1. manufacture: Mercedes
model: SLK32 AMG
convertible: hardtop
2. manufacture: Ford
model: GT90
production phase: prototype
3. manufacture: Mazda
model: MX-5
convertible: softtop
</code></pre>
<p>Now as you can see all cars are tagged with their manufacture and model, but the other categories don't all match. Note that a car can only have one of each category. IE. A car can only have one manufacturer.</p>
<p>I want to design a database to support a search for all Mercedes, or to be able to list all manufactures.</p>
<p>My current design is something like this:</p>
<pre><code>vehicles
int vid
String vin
vehicleTags
int vid
int tid
tags
int tid
String tag
int cid
categories
int cid
String category
</code></pre>
<p>I have all the right primary and foreign keys in place, except I can't handle the case where each car can only have one manufacturer. Or can I?</p>
<p>Can I add a foreign key constraint to the composite primary key in vehicleTags? IE. Could I add a constraint such that the composite primary key (vid, tid) can only be added to vehicleTags only if there isn't already a row in vehicleTags such that for the same vid, there isn't already a tid in the with the same cid?</p>
<p>My guess is no. I think the solution to this problem is add a cid column to vehicleTags, and make the new composite primary key (vid, cid). It would look like:</p>
<pre><code>vehicleTags
int vid
int cid
int tid
</code></pre>
<p>This would prevent a car from having two manufacturers, but now I have duplicated the information that tid is in cid.</p>
<p>What should my schema be?</p>
<p>Tom noticed this problem in my database schema in my previous question, <a href="https://stackoverflow.com/questions/372399/how-do-you-do-many-to-many-table-outer-joins">How do you do many to many table outer joins?</a></p>
<p><strong>EDIT</strong><br/>
I know that in the example manufacture should really be a column in the vehicle table, but let's say you can't do that. The example is just an example.</p>

373,153 | <p>When you're using a factory pattern, how do you inject dependencies into constructors at runtime?</p>
<p>I'm building Foos with different formats - boolean, array, freetext, matrix, etc. That format list will grow as we find different uses for Foo. Here's my basic core domain:</p>
<pre><code>public interface IFoo
{
FooFormat Format { get; }
}
public class Foo : IFoo
{
private FooFormat _format;
internal Foo(FooFormat format)
{
_format = format;
}
public FooFormat Format { get { return _format; } }
}
public abstract class FooFormat
{
}
public class DefaultFooFormat : FooFormat
{
}
public class BooleanFooFormat : FooFormat
{
public IList<bool> Values { get; set; }
}
public class ArrayFooFormat : FooFormat
{
private IList<string> _values;
public ArrayFooFormat(IList<string> values)
{
_values = values;
}
public IList<string> Values { get { return _values; } }
}
</code></pre>
<p>IFoo is decorated for the consumer context:</p>
<pre><code>public abstract class FooDecorator : IFoo
{
private IFoo _foo;
protected FooDecorator(IFoo foo)
{
_foo = foo;
}
public FooFormat Format
{
get { return _foo.Format; }
}
protected IFoo foo
{
get { return _foo; }
}
}
</code></pre>
<p>I don't want my consumer to instantiate a Foo directly, so I force them to use a factory:</p>
<pre><code>public abstract class FooFactory
{
protected IFoo Build<T>()
{
FooFormat format = GetFormat<T>();
return new Foo(format);
}
private FooFormat GetFormat<T>()
{
if (typeof(T) == typeof(ArrayFooFormat)) return new ArrayFooFormat(new List<string>());
if (typeof(T) == typeof(BooleanFooFormat)) return new BooleanFooFormat();
return new DefaultFooFormat();
}
}
</code></pre>
<p>And even then, they need to derive a factory from my abstract factory for their particular context.</p>
<p>I'm specifically building foos in an html context, like so:</p>
<pre><code>public class HtmlFoo : FooDecorator
{
public HtmlFoo(IFoo foo) : base(foo) { }
public string ToHtml()
{
return "<div>" + this.Format.ToString() + "</div>";
}
}
public class HtmlFooFactory : FooFactory
{
public IFoo BuildFoo<T>()
{
IFoo foo = Build<T>();
return new HtmlFoo(foo);
}
}
public class HtmlFooConsumer
{
public void DoSomeFoo()
{
var factory = new HtmlFooFactory();
var htmlBooleanFoo = factory.BuildFoo<BooleanFooFormat>();
var htmlArrayFoo = factory.BuildFoo<ArrayFooFormat>();
}
}
</code></pre>
<p>My problem is in my abstract FooFactory: I'm always injecting an empty value list into my ArrayFooFormat. I want to be able to pass in a value list from the consumer. For other FooFormats, I want to pass in the right constructor arguments from the consumer. But I want to keep the public API dead simple - I don't want a bunch of overloads on BuildFoo().</p>
<p>So how do I pass a custom value list into the factory.BuildFoo<T>() call from inside HtmlFooConsumer.DoSomeFoo()? Any ideas, stackoverflow gurus?</p>

</blockquote>
<p>I need to able to <strong>pass a reference to a function with a given set of parameters</strong>.</p>
<p>Here is an example of passing a reference <strong><em>without</strong> parameters</em>:</p>
<pre><code>var f = function () {
//Some logic here...
};
var fr = f; //Here I am passing a reference to function 'f', without parameters
fr(); //the 'f' function is invoked, without parameters
</code></pre>
<p>Now what I need to do is pass the same <code>f</code> function, but this time I would need to pass parameters to the reference. Now, I can do it with an anonymous function and invoke the <code>f</code> function with parameters inside the newly created function, like such:</p>
<pre><code>var f = function () {
//Some logic here...
};
var fr = function (pars) {
f(pars);
}; //Here I am creating an anonymous function, and invoking f inside it
fr({p : 'a parameter'}); //Invoking the fr function, that will later invoke the f function with parameters
</code></pre>
<p>But my question is, <strong>Is there a way to pass a direct reference to the <code>f</code> function With parameters to <code>fr</code>, but without enclosing it in an anonymous function?</strong></p>
<p><em>What do I need to assign to <code>fr</code> to make it invokable without parameters (<code>fr()</code>), so that f(1,2,3) is executed when <code>fr</code> is invoked?</em> </p>
<p><strong>[UPDATE]</strong>
I followed <a href="https://stackoverflow.com/questions/373157/javascript-passing-a-reference-to-a-function-with-parameters#373216">Jason Bunting</a>'s answer to <a href="https://stackoverflow.com/questions/321113">here</a> about the <em>Partial Function</em> and the JavaScript function he posts there is exactly what I was looking for. Here is the solution:</p>
<pre><code>function partial(func /*, 0..n args */) {
var args = Array.prototype.slice.call(arguments).splice(1);
return function() {
var allArguments = args.concat(Array.prototype.slice.call(arguments));
return func.apply(this, allArguments);
};
}

373,182 | <p>I bet I've got elementary question, but I couldn't solve it for two nights.
I've got 1 "ul" element and I just want it to move any amount of pixels every e.g. 2 sec to the left. I want him to move like this step by step and then come back to the original position and start moving again.
I've been stucked, my script only moves it to the final position and finish. </p>
<pre><code>window.onload = function moveUl(){
var eUl = document.getElementById('change');
var eLi = eUl.getElementsByTagName('li');
x = -300;
function move(){
for(i=0;i< eLi.length;i++){
eUl.style.marginLeft = i*x+'px';
}
}
setInterval(move,1000);
}
</code></pre>
<p>This is the simpliest I can think of. I know this script executes whole loop after 1 sec, but I try to do something like this : Move this element to the left, wait, move more to left and so on. </p>

373,212 | <p>I've created a <em>very</em> simple app, which presents an easygui entrybox() and continues to loop this indefinitely as it receives user input.</p>
<p>I can quit the program using the Cancel button as this returns None, but I would also like to be able to use the standard 'close' button to quit the program. (ie. top right of a Windows window, top left of a Mac window) This button currently does nothing.</p>
<p>Taking a look at the easygui module I found this line: </p>
<pre><code>root.protocol('WM_DELETE_WINDOW', denyWindowManagerClose )
</code></pre>
<p>This would seem to be the culprit. I'm no TKinter expert but I could probably work out how to alter this handler to act the way I want.</p>
<p>However, as I'd rather not mess about with the easygui module, Is there a way to override this behavior from my main script, and have the close button either close the program outright or return None?</p>

373,214 | <p>I was asking about specifics with this approach earlier today <a href="https://stackoverflow.com/questions/372572/how-to-block-the-ui-thread-from-another-thread-or-force-a-form-to-run-within-th">here</a> but the confused responses has me wondering if I'm going about this all wrong.</p>
<p>So here's the problem. I need to architect a WinForms application that periodically checks a value from some external service. If it is in a certain state the application is supposed to pop up a modal form blocking the user from interacting with the application until such time that the state changes. The blocked UI should act just like when a form is displayed using ShowDialog(). That is to say the user should not be able to interact with the ui in any way until the dialog is closed (in this case this can only be done by the application).</p>
<p>In my particular application I have the requirement crop up in several instances. For example, at one point the application runs a timer that repeatedly checks the value of a cell in a db table that is constantly being updated by a weighing device. If the value is below a certain threshold the user is prompted to place items on the scale - he or she may not proceed nor interact with the UI until they do so.</p>
<p>Every solution I have tried has been chock full of threading problems. Either the dialog won't block the UI, or the timer will not continue checking the external service or the application cannot close the form when the time comes.</p>
<p>This seems like a fairly standard winforms requirement and there must be a relevant design pattern that does not bring in Windows.Forms.Timer (I like keep it <a href="http://codebetter.com/blogs/jeremy.miller/archive/2007/05/30/build-your-own-cab-part-4-the-passive-view.aspx" rel="nofollow noreferrer">my views passive</a>).

373,219 | <p>I have a silverlight control which has a reference to a silverlight enabled wcf service.</p>
<p>When I add a reference to the service in my silverlight control, it adds the following to my clientconfig file:</p>
<pre><code><configuration>
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicHttpBinding_DataAccess" maxBufferSize="2147483647"
maxReceivedMessageSize="2147483647">
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="http://localhost:3097/MyApp/DataAccess.svc"
binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_DataAccess"
contract="svcMyService.DataAccess" name="BasicHttpBinding_DataAccess" />
</client>
</system.serviceModel>
</configuration>
</code></pre>
<p>How do I specify a relative url in the endpoint address instead of the absolute url? I want it to work no matter where I deploy the web app to without having to edit the clientconfig file, because the silverlight component and the web app will always be deployed together. I thought I'd be able to specify just "DataAccess.svc" but it doesn't seem to like that.</p>

373,252 | <p>Recently saw someone commending another user on their use of sizeof var instead of sizeof(type). I always thought that was just a style choice. Is there any significant difference? As an example, the lines with f and ff were considered better than the lines with g and gg:</p>
<pre><code> typedef struct _foo {} foo;
foo *f = malloc(count * sizeof f);
foo *g = malloc(sizeof(foo) * count);
foo **ff = malloc(count * sizeof *ff);
foo **gg = malloc(sizeof(foo*) * count);
</code></pre>
<p>In my opinion, the first set is just a matter of style. But in the second pair of lines, the extra second * can easily be confused for a multiplication.</p>

373,257 | <p>I have many sites that use the same root category of the Main Site. Each product that is added is added to the site it was added to (wow.) and also the Main Site. However, I would like categories on a per site basis to only appear if there are products on that site.</p>
<p>If I have:</p>
<pre><code>Category1
Category2
Category3
</code></pre>
<p>But Site1 only has products in Category1 and Category2, whereas Site2 and Site3 have products in Category2 and Category3; I only want Category1/2 to appear on Site1 and only Category2/3 to only appear on Site2 and Site3.</p>
<p>However, because all products in Site1/2/3 are also added to the Main Site; the Main Site would list Category1/2/3.</p>
<p>No products are added directly to the Main Site. It simply serves as a repository for the other sites.</p>
<p>Now, if there is no really easy way to enable this (as I'm sure), would it be as simple as writing my own theme that lists categories that only have products on the site that the template is being displayed on?</p>
<p>I am not a novice in the technologies that Magento uses; so writing custom code is no problem. I would, however, not like to edit it that much so that upgrading my code base would be easier in the future with later versions of Magento.</p>

373,258 | <p>Let's in fact generalize to a <code>c</code>-confidence interval. Let the common rate parameter be <code>a</code>. (Note that the mean of an exponential distribution with rate parameter <code>a</code> is <code>1/a</code>.)</p>
<p>First find the cdf of the sum of <code>n</code> such i.i.d. random variables. Use that to compute a <code>c</code>-confidence interval on the sum. Note that the max likelihood estimate (MLE) of the sum is <code>n/a</code>, ie, <code>n</code> times the mean of a single draw.</p>
<p>Background: This comes up in a program I'm writing to make time estimates via random samples. If I take samples according to a Poisson process (ie, the gaps between samples have an exponential distribution) and <code>n</code> of them happen during Activity X, what's a good estimate for the duration of Activity X? I'm pretty sure the answer is the answer to this question.</p>

373,261 | <p>I am developing an OpenGL application and I am seeing some strange things happen. The machine I am testing with is equipped with an NVidia Quadro FX 4600 and it is running RHEL WS 4.3 x86_64 (kernel 2.6.9-34.ELsmp).</p>
<p>I've stepped through the application with a debugger and I've noticed that it is hanging on OpenGL calls that are receiving information from the OpenGL API: i.e. - glGetError, glIsEnabled, etc. Each time it hangs up, the system is unresponsive for 3-4 seconds.</p>
<p>Another thing that is interesting is that if this same code is run on RHEL 4.5 (Kernel 2.6.9-67.ELsmp), it runs completely fine. The same code also runs perfectly on Windows XP. All machines are using the exact same hardware:</p>
<ul>
<li>PNY nVidia Quadro FX4600 768mb PCI Express </li>
<li>Dual Intel Xeon DP Quad Core E5345 2.33hz </li>
<li>4096 MB 667 MHz Fully Buffered DDR2 </li>
<li>Super Micro X7DAL-E Intel 5000X Chipset Dual Xeon Motherboard </li>
<li>Enermax Liberty 620 watt Power Supply </li>
</ul>
<p>I have upgraded to the latest 64bit drivers: Version 177.82, Release Date: Nov 12, 2008 and the result is the exact same.</p>
<p>Does anyone have any idea what could be causing the system to hang on these OpenGL calls?</p>

373,262 | <p>How can the XOR operation (on two 32 bit ints) be implemented using only basic arithmetic operations? Do you have to do it bitwise after dividing by each power of 2 in turn, or is there a shortcut? I don't care about execution speed so much as about the simplest, shortest code.</p>
<p><strong>Edit:</strong>
This is not homework, but a riddle posed on a <a href="http://www.hacker.org" rel="noreferrer">hacker.org</a>. The point is to implement XOR on a stack-based virtual machine with very limited operations (similar to the <a href="http://en.wikipedia.org/wiki/Brainfuck" rel="noreferrer">brainfuck</a> language and yes - no shift or mod). Using that VM is the difficult part, though of course made easier by an algorithm that is short and simple.</p>
<p>While FryGuy's solution is clever, I'll have to go with my original ideal (similar to litb's solution) because comparisons are difficult to use as well in that environment.</p>

I'm quite capable of building this, but i was wondering if there are many things out there like this that I could at least base mine upon. </p>
<p>I know there are standards out there for certain schema elements like this, but I've lost track of which are the best/standard and how you might extend them etc.</p>

373,328 | <p>During development (and for debugging) it is very useful to run a Java class' <em>public static void main(String[] argv)</em> method directly from inside Eclipse (using the Run As context menu).</p>
<p>Is there a similarily quick way to specify command line parameters for the run?
What I do now is go to the "Run Dialog", click through the various settings to the tab where I can specify VM and program arguments and enter them there.
Too many steps, plus I do not want to mix the more permanent runtime configuration settings with the one-off invokation parameters.
What I want instead is to check a box somewhere (or have a separate menu item "Run as Java application with command line") and then be prompted for the commandline every time (with a nice history).</p>

373,335 | <p>I'm looking for a library in Python which will provide <code>at</code> and <code>cron</code> like functionality.</p>
<p>I'd quite like have a pure Python solution, rather than relying on tools installed on the box; this way I run on machines with no cron.</p>
<p>For those unfamiliar with <code>cron</code>: you can schedule tasks based upon an expression like: </p>
<pre><code> 0 2 * * 7 /usr/bin/run-backup # run the backups at 0200 on Every Sunday
0 9-17/2 * * 1-5 /usr/bin/purge-temps # run the purge temps command, every 2 hours between 9am and 5pm on Mondays to Fridays.
</code></pre>
<p>The cron time expression syntax is less important, but I would like to have something with this sort of flexibility. </p>
<p>If there isn't something that does this for me out-the-box, any suggestions for the building blocks to make something like this would be gratefully received.</p>
<p><strong>Edit</strong>
I'm not interested in launching processes, just "jobs" also written in Python - python functions. By necessity I think this would be a different thread, but not in a different process.</p>
<p>To this end, I'm looking for the expressivity of the cron time expression, but in Python. </p>
<p>Cron <em>has</em> been around for years, but I'm trying to be as portable as possible. I cannot rely on its presence.</p>

<p>My question is, on the new line (starting with 'a'), does the white space between the 'a' and the first ' get appended to the string? Or do I need the ' to be the char next to a to prevent additional white space?</p>

373,351 | <p><strong>The situation:</strong></p>
<p>I need to convert our current development environment from Windows XP 32-bit to Windows Vista 64-bit (*). Naturally, I've run into plenty of places in our build system where hardcoded paths were problematic (e.g. "<code>C:\Program Files</code>" becoming "<code>C:\Program Files (x86)</code>"). Fortunately, there is a <code>%ProgramFiles%</code> environment variable which maps to the proper directory based on the source process (32-bit or 64-bit). So I updated the build scripts with <code>%ProgramFiles%</code>, and I was sure it'd be the end of that.</p>
<p>The build environment is called from the command-line (<code>C:\Windows\System32\cmd.exe</code>).</p>
<p><b>The problem:</b>
On one specific machine (namely my dev machine at work), it turns out that <code>C:\Windows\System32\cmd.exe</code> is actually a 32bit process, so the scripts find the <code>x86</code> version of the <code>Program Files</code> directory and everything works great.</p>
<p>On every other 64bit machine I can find (including my home machine), <code>C:\Windows\System32\cmd.exe</code> is the 64bit version, and the 32bit version is in <code>C:\Windows\SysWow64\cmd.exe</code>. So the build scripts can't find anything they're looking for and fail.</p>
<p>I understand now that the 32bit <code>cmd.exe</code> should be called explicitly if that's what you need, and by default you get a 64bit <code>cmd.exe</code>. Typical case of <code>WORKSFORME</code>...</p>
<p><b>The question is</b>, what happened to the machine where this is not true? Why am I getting a 32bit <code>cmd.exe</code> by default on one machine but not on others? In all cases I am explicitly executing <code>C:\Windows\System32\cmd.exe</code> from the <code>Start|Run</code> menu but getting different results <em>on one machine only</em>. All are running the same edition of Vista 64bit.</p>
<p>Any thoughts or insight?</p>
<p>(*) Please accept that I <em>must</em> do this. I am not at liberty to say <em>why</em> I am doing this. Re-installing the OS and everything from scratch would probably work, but it is surely overkill. Besides, it was hard enough convincing our IT department to give out Vista machines!</p>

373,357 | <p>Is there any way to get the exposure settings (aperture, shutter speed, ISO) for a photo taken on an iPhone?</p>
<p>An app running on the iPhone can use the UIImagePickerController interface for taking pictures, but that doesn't provide much info about the picture.</p>
<p>The EXIF data for a photo taken on the iPhone contains aperture info, but not shutter speed or ISO.</p>

373,366 | <p>I'm having an issue setting up one of my projects in TeamCity (v4.0), specifically when it comes to using Object Initializers.</p>
<p>The project builds fine normally, however it would seem that TeamCity transforms the build file into something it likes (some MSBuild mutation) and when it comes to compiling the code for a part of the solution it balks when it sees an Object Initializer.</p>
<p>Specifically the errors are:</p>
<pre><code>[11:16:21]: ErrorView.xaml.cs(22, 187): error CS1026: ) expected
[11:16:21]: ErrorView.xaml.cs(22, 208): error CS0116: A namespace does not directly contain members such as fields or methods
[11:16:21]: ErrorView.xaml.cs(27, 16): error CS1518: Expected class, delegate, enum, interface, or struct
[11:16:21]: ErrorView.xaml.cs(35, 16): error CS1518: Expected class, delegate, enum, interface, or struct

[11:16:21]: ErrorView.xaml.cs(48, 17): error CS1022: Type or namespace definition, or end-of-file expected
</code></pre>
<p>When I look into this further it would seem the problem ties back to the transformation of the build file to TeamCity format using CSC from the v2.0 framework directory.</p>
<p>Is it possible to compile code using object initializers (a .NET 3.0 feature) with the .NET 2.0 compiler (I would assume not, though I may be missing something), and if not, does anyone know a way to force it to use the 3.0 compiler (if one exists) or the 3.5 compiler?</p>
<p>For those interested, the CSC command being executed is:</p>

<p>Thanks!</p>
<p>Update: I have partially (read: I'm not happy with it) fixed the problem by changing the build runner from Nant to command runner - this just executed the Nant build file as it was intended without any manipulation, though the feedback level is different. Any other suggestions would be appreciated.</p>

... .replace(tzinfo=None)
datetime.datetime(2008, 12, 16, 13, 0)

<p>I.e., in English, get the current time (in UTC), convert it to some other timezone, set the time to midnight, then convert back to UTC.</p>
<p>I'm not just using now() or localtime() as that would use the server's timezone, not the user's timezone.</p>

373,387 | <p>For a project I am doing I need to manually create a .net project. I am currently using a <code>StreamWriter</code> to create the .sln, .csproj and base (empty for now) class. I am also generating the AssemblyInfo.cs class. I have copied exactly the files and folder structure VS.Net creates when you create an empty windows class library project.</p>
<p>For some reason when I try to open the .sln file nothing at all happens. I can open the .csproj file fine, but the project will not compile. I don't get any error messages, just nothing happens. I have checked all of the files I am creating against the ones created by Visual Studio using Beyond Compare and they are exactly the same except for the project name and GUID. </p>
<p>Does anyone know if Visual Studio is doing something behind the scenes when it creates a project? Is there something else I could be missing?</p>

373,421 | <p>I have analyzed a hibernate generated oracle database and discovered that a delete of a row from a single table will spawn the firing of 1200+ triggers in order to delete the related rows in child tables. The triggers are all auto-generated the same - an automatic delete of a child row without checking for existence first. As it is impossible to predict which child tables will actually have related rows, I think a viable solution to preventing the firing of the cascaded delete down a deeply branched completely empty limb, would be to check for the existence of a related row before attempting to delete. In other dbms', I could simply state " if exists....." before deleting. Is there a comparable way to do this in oracle?</p>

Most days there are hours that do not have any activity and therefore where the query is run the count of activities per hour show up but there are gaps and the query excludes these. We still want to show the hours that do not have activity and display a zero so that zero value can then be charted. The query we using looks like this …</p>
<pre><code>select datepart(Year, dev_time) as Year,
datepart(Month, dev_time) as Month,
datepart(Day, dev_time) as Day,
datepart(Hour, dev_time) as Hour,
count(tdm_msg) as Total_ACTIVITES
from TCKT_ACT
where tdm_msg = ‘4162′ and dev_time >= DATEADD(day, - 1, GETDATE())
group by datepart(Year, dev_time) ,
datepart(Month, dev_time) ,
datepart(Day, dev_time),
datepart(Hour, dev_time)
order by datepart(Year, dev_time) asc,
datepart(Month, dev_time) asc,
datepart(Day, dev_time) asc,
datepart(Hour, dev_time) asc

373,520 | <p>I have a program in Perl I'm working on where I would need multiple keys, and a way of giving each key multiple values and follow that by being able to both read them in and write them out to an external file depending on if the key matches what the person enters into standard input. I've looked across several sites and have found information somewhat useful in reading in hashes of arrays, but not writing them out, and I would also need to be able able to add to the array in the external file.</p>
<p>Is this possible?</p>
<p>Edit:
Is there a way that it could be done with starter Perl? I'm a beginner. Hashes of arrays seemed like the best way to make it work, but what I really need is a way to show multiple values for the same key while only showing the key once.</p>

373,541 | <p>I need to do a LINQ2DataSet query that does a join on more than one field (as</p>
<pre><code>var result = from x in entity
join y in entity2
on x.field1 = y.field1
and
x.field2 = y.field2
</code></pre>
<p>I have yet found a suitable solution (I can add the extra constraints to a where clause, but this is far from a suitable solution, or use <a href="https://stackoverflow.com/questions/345427/linq-to-sql-join-multiple-columns-from-the-same-table">this</a> solution, but that assumes an equijoin).</p>
<p>Is it possible in LINQ to join on multiple fields in a single join?</p>
<p><strong>EDIT</strong></p>
<pre><code>var result = from x in entity
join y in entity2
on new { x.field1, x.field2 } equals new { y.field1, y.field2 }
</code></pre>
<p>is the solution I referenced as assuming an equijoin above.</p>
<p>Further <strong>EDIT</strong></p>
<p>To answer criticism that my original example was an equijoin, I do acknowledge that, My current requirement is for an equijoin and I have already employed the solution I referenced above.</p>
<p>I am, however, trying to understand what possibilities and best practices I have / should employ with LINQ. I am going to need to do a Date range query join with a table ID soon, and was just pre-empting that issue, It looks like I shall have to add the date range in the where clause.</p>
<p>Thanks, as always, for all suggestions and comments given</p>

373,589 | <p>I'm playing with the new geography column in SQL Server 2008 and the STGeomFromText function. Here is my code (works with AdventureWorks2008)</p>
<pre><code>DECLARE @region geography;
set @region = geography::STGeomFromText('POLYGON((
-80.0 50.0, -90.0 50.0,
-90.0 25.0, -80.0 25.0,
-80.0 50.0))', 4326);
SELECT @region;
</code></pre>
<p>My question is about the 4326 in the code. It is supposed to be a spacial Reference ID. When I go to MSDN there isn't a lot on it. If I change the value to 56 I get an error telling me the value must be in the sys.spatial_reference_systems table.</p>
<p>You can look at that table by executing:</p>
<pre><code>select * from sys.spatial_reference_systems
</code></pre>
<p>There is a well_known_text column in that table, but it doesn't tell me much. The value for 4326 is:</p>
<pre><code>GEOGCS["WGS 84", DATUM["World Geodetic System 1984", ELLIPSOID["WGS 84", 6378137, 298.257223563]], PRIMEM["Greenwich", 0], UNIT["Degree", 0.0174532925199433]]
</code></pre>
<p>Can anyone explain this mystery to me? What is the SRID?</p>

373,599 | <p>I am using a route like this one:</p>
<pre><code>routes.MapRoute("Invoice-New-NewCustomer",
"Invoice/New/Customer/New/{*name}",
new { controller = "Customer", action = "NewInvoice" },
new { name = @"[^\.]*" });
</code></pre>
<p>There is an action which handles this route:</p>
<pre><code>public ActionResult NewInvoice(string name)
{
AddClientSideValidation();
CustomerViewData viewData = GetNewViewData();
viewData.InvoiceId = "0";
viewData.Customer.Name = name;
return View("New", viewData);
}
</code></pre>
<p>When I call <code>return RedirectToAction("NewInvoice", "Customer", new {name});</code> and name is equal to "The C# Guy", the "name" parameter is truncated to "The C".</p>
<p>So my question is : What is the best way to handle this kind of special character with ASP.NET MVC?</p>
<p>Thanks!</p>

373,615 | <p><strong>The question, in brief:</strong></p>
<p>In MVC, how do you distinguish between a checkbox click (or a selectbox or listbox change) from a human meaning "Controller, modify the model", and a checkbox click (or a selectbox or listbox change) from the Controller meaning "I'm updating the view because the model has changed"?</p>
<hr>
<p><strong>The example:</strong></p>
<p>I have a JS app (all one big HTML+JS page; there's a server behind it, and AJAX going on, but it's not important to the example) which has the notion of "Vertices" connected by "Edges". The UI lets you add and remove Vertices on a map, and enable or disable Edges between pairs of Vertices.</p>
<p>There are two ways to disable an Edge from Vertex A to Vertex B:</p>
<ol>
<li>click on the Edge to make the "Edge Details" window provide you with a "Disable This Edge" button; or</li>
<li>click on Vertex A (or B) to make the "Vertex Details" window provide you with a checklist of nearby Vertices, from which you can uncheck Vertex B (or A).</li>
</ol>
<p>Here's how this works under the hood in MVC (<em>but see the end of this post for an update, where I correct problems in my understanding</em>):</p>
<ul>
<li>Model: a list of Vertex objects and a list of Edge objects.</li>
<li>View: a GMaps UI, with markers and polylines, plus checkboxes and buttons and "Vertex Details" and "Edge Details" DIVs.</li>
<li>Controller:
<ul>
<li>JS functions that update the model when events on the checkboxes and buttons fire; and</li>
<li>JS functions that update the view when events on the models fire.</li>
</ul></li>
</ul>
<p><strong>Here's the specific inelegance</strong>:</p>
<ol>
<li>The user has the Vertex Details Window focused on Vertex A, and the Edge Details Window focused on the Edge from Vertex A to Vertex B.</li>
<li>The user clicks "Disable This Edge" in the Edge Details window.</li>
<li>Controller function 1 gets the click event, and calls disable() on the Edge model object.</li>
<li>The Edge model object fires the "I just got disabled" event.</li>
<li>Controller function 2 receives the "I just got disabled" event, and
<ol>
<li>redraws the Edge Details Window to say "I'm disabled!" and</li>
<li><strong>unchecks Vertex B in the Vertex Details Window.</strong>
<ol>
<li><strong>Crap!</strong> This fires Controller function 1 again, which was listening for UI events that mean an edge was disabled!</li>
</ol></li>
</ol></li>
</ol>
<p>So there's an unnecessary re-update of the Model, and re-update of the View. In a more complex view with events that fire events that fire events, this can make for dozens of extraneous updates!</p>
<p><hr>
<strong>Update: a great answer.</strong></p>
<p>I misunderstood MVC a bit. I don't have just one View, as I described above: I have several Views into several Models. In particular, I have a checkbox-list View of Edges to a particular Node, and a separate, "detailed window-style" View of an Edge.</p>
<p>Furthermore, I shouldn't have one controller function updating all views when the Model changes: each View should modify <em>itself</em> when the Model changes.</p>
<p>So if each View registers for "state updated" events on the Model, and each View updates itself upon receipt of those events, then the answer to my circular events question is simply this:</p>
<p><strong>The checkbox-list View will disable checkbox events for the moment that it is updating the checkboxes after a Model state change.</strong></p>
<p>Now if a user disables an Edge via the Edge Detail window, the Controller updates the Edge Model, the checkbox-list View receives notification of the update, and the checkbox-list View is smart enough to silence checkbox events while changing the status of the appropriate checkbox.</p>
<p>This is much more palatable than my original solution, where one Controller updates ALL Views -- and thus has to know which views need special care and feeding to avoid loops. Instead, only the single View with troublesome UI elements has to deal with the problem. </p>
<p>Thanks to those who answered my question!</p>

373,626 | <p>In all my projects till now, I use to use singleton pattern to access Application configuration throughout the application. Lately I see lot of articles taking about not to use singleton pattern , because this pattern does not promote of testability also it hides the Component dependency.
My question is what is the best way to store Application configuration, which is easily accessible throughout the application without passing the configuration object all over the application ?.</p>
