67,859 | <p>I am trying to create a query string of variable assignments separated by the <code>&</code> symbol (ex: <code>"var1=x&var2=y&..."</code>). I plan to pass this string into an embedded flash file.</p>
<p>I am having trouble getting an <code>&</code> symbol to show up in XSLT. If I just type <code>&</code> with no tags around it, there is a problem rendering the XSLT document. If I type <code>&amp;</code> with no tags around it, then the output of the document is <code>&amp;</code> with no change. If I type <code><xsl:value-of select="&" /></code> or <code><xsl:value-of select="&amp;" /></code> I also get an error. Is this possible? Note: I have also tried <code>&amp;amp;</code> with no success.</p>

67,879 | <p>I have an application that runs as a child application in a virtual directory.</p>
<p>I want to pass a value from the parent application, but I believe that Session is keyed per application, and won't work.</p>
<p>To further complicate things, the parent application is WebForms, while the child is NVelocity MVC.</p>
<p>Does anyone know a trick that allows me to use some sort of Session type functionality between virtual applications?</p>
<p>EDIT: A webservice isn't really what I had in mind, all I need to do is pass the logged in users username to the child app. Besides, if calling a webservice back on the parent, I won't get the same session, so I won't know what user.</p>

67,890 | <p>I'm writing a web app that points to external links. I'm looking to create a non-sequential, non-guessable id for each document that I can use in the URL. I did the obvious thing: treating the url as a string and str#crypt on it, but that seems to choke on any non-alphanumberic characters, like the slashes, dots and underscores.</p>
<p>Any suggestions on the best way to solve this problem?</p>
<p>Thanks!</p>

<p>The line <code>parents.ForEach(Function(p) p.sub_account_groups = sql_func(p))</code> has this error...</p>
<blockquote>
<p>Operator '=' is not defined for types 'System.Collections.Generic.IList(Of st.data.AccountGroup)' and 'System.Collections.Generic.List(Of st.data.AccountGroup)'. </p>

<p>but I really can't see how it is any different from this code from Rob Connery</p>
<pre><code>public IList<Category> GetCategories() {
IList<Category> rawCategories = _repository.GetCategories().ToList();
var parents = (from c in rawCategories
where c.ParentID == 0

parents.ForEach(p =>
{
p.SubCategories = (from subs in rawCategories

select subs).ToList();

return parents;

<p>which compiles perfectly... what am I doing incorrectly?</p>

67,959 | <p>I've run into a few gotchas when doing C# XML serialization
that I thought I'd share:</p>
<ul>
<li>You can't serialize items that are read-only (like KeyValuePairs)</li>
<li>You can't serialize a generic dictionary. Instead, try this wrapper class (from <a href="http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx" rel="noreferrer">http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx</a>):</li>
</ul>
<hr/>
<pre><code>using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;
[XmlRoot("dictionary")]
public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable

<p>If I wrap JavaScript code in an anonymous function to avoid making variables <code>public</code> the functions within the JavaScript are not available from within the html that includes the JavaScript. </p>
<p>On initially loading the page the JavaScript loads and is executed but on subsequent reloads of the page the JavaScript code does not go through the execution process again.

68,067 | <p>I'm using BlogEngine.NET (a fine, fine tool) and I was playing with the TinyMCE editor and noticed that there's a place for me to create a list of external links, but it has to be a javascript file:</p>
<p><code>external_link_list_url : "example_link_list.js"</code></p>
<p>this is great, of course, but the list of links I want to use needs to be generated dynamically from the database. This means that I need to create this JS file from the server on page load. Does anyone know of a way to do this? Ideally, I'd like to just overwrite this file each time the editor is accessed.</p>

68,103 | <p>I have a XULRunner application that needs to copy image data to the clipboard. I have figured out how to handle copying text to the clipboard, and I can paste PNG data from the clipboard. What I can't figure out is how to get data from a data URL into the clipboard so that it can be pasted into other applications.</p>
<p>This is the code I use to copy text (well, XUL):</p>
<pre><code>var transferObject=Components.classes["@mozilla.org/widget/transferable;1"].
createInstance(Components.interfaces.nsITransferable);
var stringWrapper=Components.classes["@mozilla.org/supports-string;1"].
createInstance(Components.interfaces.nsISupportsString);
var systemClipboard=Components.classes["@mozilla.org/widget/clipboard;1"].
createInstance(Components.interfaces.nsIClipboard);
var objToSerialize=aDOMNode;
transferObject.addDataFlavor("text/xul");
var xmls=new XMLSerializer();
var serializedObj=xmls.serializeToString(objToSerialize);
stringWrapper.data=serializedObj;
transferObject.setTransferData("text/xul",stringWrapper,serializedObj.length*2);
</code></pre>
<p>And, as I said, the data I'm trying to transfer is a PNG as a data URL. So I'm looking for the equivalent to the above that will allow, e.g. Paint.NET to paste my app's data.</p>

68,120 | <p>I'm not overly familiar with Tomcat, but my team has inherited a complex project that revolves around a Java Servlet being hosted in Tomcat across many servers. Custom configuration management software is used to write out the server.xml, and various resources (connection pools, beans, server variables, etc) written into server.xml configure the servlet. This is all well and good.</p>
<p>However, the names of some of the resources aren't known in advance. For example, the Servlet may need access to any number of "Anonymizers" as configured by the operator. Each anonymizer has a unique name associated with it. We create and configure each anonymizer using java beans similar to the following:</p>
<pre><code><Resource
name="bean/Anonymizer_toon"
type="com.company.tomcatutil.AnonymizerBean"
factory="org.apache.naming.factory.BeanFactory"
className="teAnonymizer"
databaseId="50"
/>
<Resource
name="bean/Anonymizer_default"
type="com.company.tomcatutil.AnonymizerBean"
factory="org.apache.naming.factory.BeanFactory"
className="teAnonymizer"
databaseId="54"
/>
</code></pre>
<p>However, this appears to require us to have explicit entries in the Servlet's context.xml file for each an every possible resource name in advance. I'd like to replace the explicit context.xml entries with wildcards, or know if there is a better solution to this type of problem.</p>
<p>Currently:</p>
<pre><code> <ResourceLink name="bean/Anonymizer_default"
global="bean/Anonymizer_default"
type="com.company.tomcatutil.AnonymizerBean"/>
<ResourceLink name="bean/Anonymizer_toon"
global="bean/Anonymizer_toon"
type="com.company.tomcatutil.AnonymizerBean"/>
</code></pre>
<p>Replaced with something like:</p>
<pre><code> <ResourceLink name="bean/Anonymizer_*"
global="bean/Anonymizer_*"
type="com.company.tomcatutil.AnonymizerBean"/>
</code></pre>
<p>However, I haven't been able to figure out if this is possible or what the correct syntax might be. Can anyone make any suggestions about better ways to handle this?</p>

68,150 | <p>I took a data structures class in C++ last year, and consequently implemented all the major data structures in templated code. I saved it all on a flash drive because I have a feeling that at some point in my life, I'll use it again.

68,165 | <p>I have a link on a long HTML page. When I click it, I wish a <code>div</code> on another part of the page to be visible in the window by scrolling into view.</p>
<p>A bit like <code>EnsureVisible</code> in other languages.</p>
<p>I've checked out <code>scrollTop</code> and <code>scrollTo</code> but they seem like red herrings.</p>
<p>Can anyone help?</p>

68,234 | <p>Let’s say I'm developing a helpdesk application that will be used by multiple departments. Every URL in the application will include a key indicating the specific department. The key will always be the first parameter of every action in the system. For example</p>
<pre><code>http://helpdesk/HR/Members
http://helpdesk/HR/Members/PeterParker
http://helpdesk/HR/Categories
http://helpdesk/Finance/Members
http://helpdesk/Finance/Members/BruceWayne
http://helpdesk/Finance/Categories
</code></pre>
<p>The problem is that in each action on each request, I have to take this parameter and then retrieve the Helpdesk Department model from the repository based on that key. From that model I can retrieve the list of members, categories etc., which is different for each Helpdesk Department. This obviously violates DRY.</p>
<p>My question is, how can I create a base controller, which does this for me so that the particular Helpdesk Department specified in the URL is available to all derived controllers, and I can just focus on the actions?</p>

68,247 | <p>I sometimes need to modify OSS code or other peoples' code (usually C-based, but sometimes C++/Java) and find myself "grep"ing headers for types, function declarations etc. as I follow code flow and try to understand the system. Is there a good tool that exists to aid in code browsing. I'd love to be able to click on a type and be taken to the declaration or click on a function name and be taken to it's implementation. I'm on a linux box, so replies like "just use Visual Studio" won't necessarily work for me. Thanks!</p>

68,282 | <p>When defining a method on a class in Python, it looks something like this:</p>
<pre><code>class MyClass(object):
def __init__(self, x, y):
self.x = x
self.y = y
</code></pre>
<p>But in some other languages, such as C#, you have a reference to the object that the method is bound to with the "this" keyword without declaring it as an argument in the method prototype. </p>
<p>Was this an intentional language design decision in Python or are there some implementation details that require the passing of "self" as an argument?</p>

68,323 | <p>Working on a project at the moment and we have to implement soft deletion for the majority of users (user roles). We decided to add an <code>is_deleted='0'</code> field on each table in the database and set it to <code>'1'</code> if particular user roles hit a delete button on a specific record.</p>
<p>For future maintenance now, each <code>SELECT</code> query will need to ensure they do not include records <code>where is_deleted='1'</code>.</p>
<p>Is there a better solution for implementing soft deletion?</p>
<p>Update: I should also note that we have an Audit database that tracks changes (field, old value, new value, time, user, ip) to all tables/fields within the Application database.</p>

68,346 | <p>Here's a problem I've been trying to solve at work. I'm not a database expert, so that perhaps this is a bit sophomoric. All apologies.</p>
<p>I have a given database D, which has been duplicated on another machine (in a perhaps dubious manner), resulting in database D'. It is my task to check that database D and D' are in fact exactly identical.</p>
<p>The problem, of course, is what to actually do if they are not. For this purpose, my thought was to run a symmetric difference on each corresponding table and see the differences.</p>
<p>There is a "large" number of tables, so I do not wish to run each symmetric difference by hand. How do I then implement a symmetric difference "function" (or stored procedure, or whatever you'd like) that can run on arbitrary tables without having to explicitly enumerate the columns?</p>
<p>This is running on Windows, and your hedge fund will explode if you don't follow through. Good luck.</p>

68,352 | <p>I use this question in interviews and I wonder what the best solution is.</p>
<p>Write a Perl sub that takes <em>n</em> lists, and then returns 2^<em>n</em>-1 lists telling you which items are in which lists; that is, which items are only in the first list, the second, list, both the first and second list, and all other combinations of lists. Assume that <em>n</em> is reasonably small (less than 20).</p>
<p>For example:</p>
<pre><code>list_compare([1, 3], [2, 3]);
=> ([1], [2], [3]);
</code></pre>
<p>Here, the first result list gives all items that are only in list 1, the second result list gives all items that are only in list 2, and the third result list gives all items that are in both lists.</p>
<pre><code>list_compare([1, 3, 5, 7], [2, 3, 6, 7], [4, 5, 6, 7])
=> ([1], [2], [3], [4], [5], [6], [7])
</code></pre>
<p>Here, the first list gives all items that are only in list 1, the second list gives all items that are only in list 2, and the third list gives all items that are in both lists 1 and 2, as in the first example. The fourth list gives all items that are only in list 3, the fifth list gives all items that are only in lists 1 and 3, the sixth list gives all items that are only in lists 2 and 3, and the seventh list gives all items that are in all 3 lists.</p>
<p>I usually give this problem as a follow up to the subset of this problem for <em>n</em>=2.</p>
<p>What is the solution? </p>
<p>Follow-up: The items in the lists are strings. There might be duplicates, but since they are just strings, duplicates should be squashed in the output. Order of the items in the output lists doesn't matter, the order of the lists themselves does.</p>

68,391 | <p>In an effort to reduce code duplication in my little Rails app, I've been working on getting common code between my models into it's own separate module, so far so good.</p>
<p>The model stuff is fairly easy, I just have to include the module at the beginning, e.g.:</p>
<pre><code>class Iso < Sale
include Shared::TracksSerialNumberExtension
include Shared::OrderLines
extend Shared::Filtered
include Sendable::Model
validates_presence_of :customer
validates_associated :lines
owned_by :customer
def initialize( params = nil )
super
self.created_at ||= Time.now.to_date
end
def after_initialize
end
order_lines :despatched
# tracks_serial_numbers :items
sendable :customer
def created_at=( date )
write_attribute( :created_at, Chronic.parse( date ) )
end
end
</code></pre>
<p>This is working fine, now however, I'm going to have some controller and view code that's going to be common between these models as well, so far I have this for my sendable stuff:</p>
<pre><code># This is a module that is used for pages/forms that are can be "sent"
# either via fax, email, or printed.
module Sendable
module Model
def self.included( klass )
klass.extend ClassMethods
end
module ClassMethods
def sendable( class_to_send_to )
attr_accessor :fax_number,
:email_address,
:to_be_faxed,
:to_be_emailed,
:to_be_printed
@_class_sending_to ||= class_to_send_to
include InstanceMethods
end
def class_sending_to
@_class_sending_to
end
end # ClassMethods
module InstanceMethods
def after_initialize( )
super
self.to_be_faxed = false
self.to_be_emailed = false
self.to_be_printed = false
target_class = self.send( self.class.class_sending_to )
if !target_class.nil?
self.fax_number = target_class.send( :fax_number )
self.email_address = target_class.send( :email_address )
end
end
end
end # Module Model
end # Module Sendable
</code></pre>
<p>Basically I'm planning on just doing an include Sendable::Controller, and Sendable::View (or the equivalent) for the controller and the view, but, is there a cleaner way to do this? I 'm after a neat way to have a bunch of common code between my model, controller, and view.</p>
<p>Edit: Just to clarify, this just has to be shared across 2 or 3 models.</p>

<pre><code><a href='<%# "/Admin/Content/EditResource.aspx?ResourceId=" + Eval("Id").ToString() %>'>Edit</a>

<p>I see this practice everywhere but it seems weird to me as I no longer am able to get compile time errors if I change the property name.
My preferred approach is to do something like this</p>
<pre><code><a runat="server" id="MyLink">Edit</a>

<p>and then in the code behind</p>
<pre><code>MyLink.Href= "/Admin/Content/EditResource.aspx?ResourceId=" + myObject.Id;

<p>I'm really interested to hear if people think the above approach is better since that's what I always see on popular coding sites and blogs (e.g. Scott Guthrie) and it's smaller code, but I tend to use ASP.NET because it is compiled and prefer to know if something is broken at compile time, not run time.</p>

68,537 | <p>A basic problem I run into quite often, but ever found a clean solution to, is one where you want to code behaviour for interaction between different objects of a common base class or interface. To make it a bit concrete, I'll throw in an example;</p>
<p><em>Bob has been coding on a strategy game which supports "cool geographical effects". These round up to simple constraints such as if troops are walking in water, they are slowed 25%. If they are walking on grass, they are slowed 5%, and if they are walking on pavement they are slowed by 0%.</em></p>
<p><em>Now, management told Bob that they needed new sorts of troops. There would be jeeps, boats and also hovercrafts. Also, they wanted jeeps to take damage if they went drove into water, and hovercrafts would ignore all three of the terrain types. Rumor has it also that they might add another terrain type with even more features than slowing units down and taking damage.</em></p>
<p>A very rough pseudo code example follows:</p>
<pre><code>public interface ITerrain
{
void AffectUnit(IUnit unit);
}
public class Water : ITerrain
{
public void AffectUnit(IUnit unit)
{
if (unit is HoverCraft)
{
// Don't affect it anyhow
}
if (unit is FootSoldier)
{
unit.SpeedMultiplier = 0.75f;
}
if (unit is Jeep)
{
unit.SpeedMultiplier = 0.70f;
unit.Health -= 5.0f;
}
if (unit is Boat)
{
// Don't affect it anyhow
}
/*
* List grows larger each day...
*/
}
}
public class Grass : ITerrain
{
public void AffectUnit(IUnit unit)
{
if (unit is HoverCraft)
{
// Don't affect it anyhow
}
if (unit is FootSoldier)
{
unit.SpeedMultiplier = 0.95f;
}
if (unit is Jeep)
{
unit.SpeedMultiplier = 0.85f;
}
if (unit is Boat)
{
unit.SpeedMultiplier = 0.0f;
unit.Health = 0.0f;
Boat boat = unit as Boat;
boat.DamagePropeller();
// Perhaps throw in an explosion aswell?
}

<p>As you can see, things would have been better if Bob had a solid design document from the beginning. As the number of units and terrain types grow, so does code complexity. Not only does Bob have to worry about figuring out which members might need to be added to the unit interface, but he also has to repeat alot of code. It's very likely that new terrain types require additional information from what can be obtained from the basic IUnit interface. </p>
<p>Each time we add another unit into the game, each terrain must be updated to handle the new unit. Clearly, this makes for a lot of repetition, not to mention the ugly runtime check which determines the type of unit being dealt with. I've opted out calls to the specific subtypes in this example, but those kinds of calls are neccessary to make. <em>An example would be that when a boat hits land, its propeller should be damaged. Not all units have propellers.</em></p>
<p>I am unsure what this kind of problem is called, but it is a many-to-many dependence which I have a hard time decoupling. I don't fancy having 100's of overloads for each IUnit subclass on ITerrain as I would want to come clean with coupling.</p>
<p>Any light on this problem is highly sought after. Perhaps I'm thinking way out of orbit all together?</p>

68,543 | <p>So, I am kinda new to ASP.net development still, and I already don't like the stock ASP.net controls for displaying my database query results in table format. (I.e. I would much rather handle the HTML myself and so would the designer!)</p>
<p>So my question is: What is the best and most secure practice for doing this without using ASP.net controls? So far my only idea involves populating my query result during the Page_Load event and then exposing a DataTable through a getter to the *.aspx page. From there I think I could just iterate with a foreach loop and craft my table as I see fit.</p>

68,561 | <p>1, Create and build a default Windows Forms project and look at the project properties. It says that the project is targetting .NET Framework 2.0. </p>
<p>2, Create a Setup project that installs just the single executable from the Windows Forms project. </p>
<p>3, Run that installer and it always says that it needs to install .NET 3.5 SP1 on the machine. But it obviously only really needs 2.0 and so I do not want customers to be forced to install .NET 3.5 when they do not need it. They might already have 2.0 installed and so forcing the upgrade is not desirable!</p>
<p>I have looked at the prerequisites of the setup project and checked the .NET Framework 2.0 entry and all the rest are unchecked. So I cannot find any reason for this strange runtime requirement. Anybody know how to resolve this one?</p>

68,572 | <p>I have a question that I may be over thinking at this point but here goes...</p>
<p>I have 2 classes Users and Groups. Users and groups have a many to many relationship and I was thinking that the join table group_users I wanted to have an IsAuthorized property (because some groups are private -- users will need authorization). </p>
<p><strong>Would you recommend creating a class for the join table as well as the User and Groups table?</strong> Currently my classes look like this.</p>
<pre><code>public class Groups
{
public Groups()
{
members = new List<Person>();
}
...
public virtual IList<Person> members { get; set; }
}
public class User
{
public User()
{
groups = new Groups()
}
...
public virtual IList<Groups> groups{ get; set; }
}
</code></pre>
<p>My mapping is like the following in both classes (I'm only showing the one in the users mapping but they are very similar):</p>
<pre><code>HasManyToMany<Groups>(x => x.Groups)
.WithTableName("GroupMembers")
.WithParentKeyColumn("UserID")
.WithChildKeyColumn("GroupID")
.Cascade.SaveUpdate();
</code></pre>
<p><strong>Should I write a class for the join table that looks like this?</strong></p>
<pre><code>public class GroupMembers
{
public virtual string GroupID { get; set; }
public virtual string PersonID { get; set; }
public virtual bool WaitingForAccept { get; set; }
}
</code></pre>
<p>I would really like to be able to adjust the group membership status and I guess I'm trying to think of the best way to go about this. </p>

68,614 | <p>I have a large application that uses EJB 2.x entity beans (BMP). This is well-known to be a horrible persistence strategy (I can elaborate if necessary).</p>
<p>I'd like to start migrating this application to use a much more expressive, transparent, and non-invasive persistence strategy, and given my company's previous experience with it, Hibernate 3.x is the obvious choice.</p>
<p>Migrating to Hibernate is going to take a while, as over 100 tables in the application use entity beans. So I'm looking at a phased approach where the two persistence strategies run in parallel, ideally on the same tables at the same time, if possible.</p>
<p>My question is, what are the pitfalls (if any) of combining these two persistence strategies? Will they get in each other's way?</p>

<p>All things being equal, do you write phone.dial(phoneNumber) or phoneNumber.dialOn(phone)? Keep in mind possible future requirements (account numbers in addition to phone numbers, calculators in addition to phones).</p>
<p>The choice tends to illustrate how the idioms of Information Expert, Single Responsibility Principle, and Tell Don't Ask are at odds with each other.</p>
<p>phoneNumber.dialOn(phone) favors Information Expert and Tell Don't Ask, while phone.dial(phoneNumber) favors Single Responsibility Principle.</p>

I have come up with one that will match a method declaration, but it requires the opening bracket of the method to be on the same line as the declaration. If you have any suggestions to improve my regex or simply have a better one then please submit an answer.</p>
<p>Here is my regex: <code>"\w+ +\w+ *\(.*\) *\{"</code></p>
<p>For those who do not know what a java method looks like I'll provide a basic one:</p>
<pre><code>int foo()
{
}
</code></pre>
<p>There are several optional parts to java methods that may be added as well but those are the only parts that a method is guaranteed to have.</p>
<p>Update:
My current Regex is <code>"\w+ +\w+ *\([^\)]*\) *\{"</code> so as to prevent the situation that Mike and adkom described.</p>

68,677 | <p>I'm using SQL Server 2000 to print out some values from a table using <code>PRINT</code>. With most non-string data, I can cast to nvarchar to be able to print it, but binary values attempt to convert using the bit representation of characters. For example:</p>
<pre><code>DECLARE @binvalue binary(4)
SET @binvalue = 0x12345678
PRINT CAST(@binvalue AS nvarchar)
</code></pre>
<p>Expected:</p>
<blockquote>
<p>0x12345678</p>
</blockquote>
<p>Instead, it prints two gibberish characters.</p>
<p>How can I print the value of binary data? Is there a built-in or do I need to roll my own?</p>
<p>Update: This isn't the only value on the line, so I can't just PRINT @binvalue. It's something more like PRINT N'other stuff' + ???? + N'more stuff'. Not sure if that makes a difference: I didn't try just PRINT @binvalue by itself.</p>

68,711 | <p>any idea how if the following is possible in PHP as a single line ?:</p>
<pre><code><?php
$firstElement = functionThatReturnsAnArray()[0];
</code></pre>
<p>... It doesn't seem to 'take'. I need to do this as a 2-stepper:</p>
<pre><code><?php
$allElements = functionThatReturnsAnArray();
$firstElement = $allElements[0];
</code></pre>
<p>... just curious - other languages I play with allow things like this, and I'm lazy enoug to miss this in PHP ... any insight appreciated ...</p>

68,750 | <p>This should hopefully be a simple one.</p>
<p>I would like to add an extension method to the System.Web.Mvc.ViewPage< T > class.</p>
<p>How should this extension method look?</p>
<p>My first intuitive thought is something like this:</p>
<pre><code>namespace System.Web.Mvc
{
public static class ViewPageExtensions
{
public static string GetDefaultPageTitle(this ViewPage<Type> v)
{
return "";
}
}
}
</code></pre>
<p><strong>Solution</strong></p>
<p>The general solution is <a href="https://stackoverflow.com/questions/68750/how-do-you-write-a-c-extension-method-for-a-generically-typed-class#68772">this answer</a>.</p>
<p>The specific solution to extending the System.Web.Mvc.ViewPage class is <a href="https://stackoverflow.com/questions/68750/how-do-you-write-a-c-extension-method-for-a-generically-typed-class#68802">my answer</a> below, which started from the <a href="https://stackoverflow.com/questions/68750/how-do-you-write-a-c-extension-method-for-a-generically-typed-class#68772">general solution</a>.</p>
<p>The difference is in the specific case you need both a generically typed method declaration AND a statement to enforce the generic type as a reference type.</p>

68,821 | <p>I want to dynamically hide/show some of the columns in a NSTableView, based on the data that is going to be displayed - basically, if a column is empty I'd like the column to be hidden. I'm currently populating the table with a controller class as the delegate for the table.</p>
<p>Any ideas? I see that I can set the column hidden in Interface Builder, however there doesn't seem to be a good time to go through the columns and check if they are empty or not, since there doesn't seem to be a method that is called before/after all of the data in the table is populated.</p>

68,843 | <p>How does the compiler know the prototype of sleep function or even printf function, when I did not include any header file in the first place?</p>
<p>Moreover, if I specify <code>sleep(1,1,"xyz")</code> or any arbitrary number of arguments, the compiler still compiles it.
But the strange thing is that gcc is able to find the definition of this function at link time, I don't understand how is this possible, because actual <code>sleep()</code> function takes a single argument only, but our program mentioned three arguments.</p>
<pre><code>/********************************/

69,000 | <p>I have a WPF application in VS 2008 with some web service references. For varying reasons (max message size, authentication methods) I need to manually define a number of settings in the WPF client's app.config for the service bindings.</p>
<p>Unfortunately, this means that when I update the service references in the project we end up with a mess - multiple bindings and endpoints. Visual Studio creates new bindings and endpoints with a numeric suffix (ie "Service1" as a duplicate of "Service"), resulting in an invalid configuration as there may only be a single binding per service reference in a project.</p>
<p>This is easy to duplicate - just create a simple "Hello World" ASP.Net web service and WPF application in a solution, change the maxBufferSize and maxReceivedMessageSize in the app.config binding and then update the service reference.</p>
<p>At the moment we are working around this by simply undoing checkout on the app.config after updating the references but I can't help but think there must be a better way!</p>
<p>Also, the settings we need to manually change are:</p>
<pre><code><security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm" />
</security>
</code></pre>
<p>and:</p>
<pre><code><binding maxBufferSize="655360" maxReceivedMessageSize="655360" />
</code></pre>
<p>We use a service factory class so if these settings are somehow able to be set programmatically that would work, although the properties don't seem to be exposed.</p>

69,030 | <p>I have a script for OS X 10.5 that focuses the Search box in the Help menu of any application. I have it on a key combination and, much like Spotlight, I want it to toggle when I run the script. So, I want to detect if the search box is already focused for typing, and if so, type Esc instead of clicking the Help menu.</p>
<p>Here is the script as it stands now:</p>
<pre><code>tell application "System Events"
tell (first process whose frontmost is true)
set helpMenuItem to menu bar item "Help" of menu bar 1
click helpMenuItem
end tell
end tell
</code></pre>
<p>And I'm thinking of something like this:</p>
<pre><code>tell application "System Events"
tell (first process whose frontmost is true)
set helpMenuItem to menu bar item "Help" of menu bar 1
set searchBox to menu item 1 of menu of helpMenuItem
if (searchBox's focused) = true then
key code 53 -- type esc
else
click helpMenuItem
end if
end tell
end tell
</code></pre>
<p>... but I get this error:</p>
<blockquote>
<p>Can’t get focused of {menu item 1 of menu "Help" of menu bar item "Help" of menu bar 1 of application process "Script Editor" of application "System Events"}.</p>
</blockquote>
<p>So is there a way I can get my script to detect whether the search box is already focused?</p>
<hr>
<p>I solved my problem by <a href="https://stackoverflow.com/questions/69391/">working around it</a>. I still don't know how to check if a menu item is selected though, so I will leave this topic open.</p>

69,115 | <p>Below is my current char* to hex string function. I wrote it as an exercise in bit manipulation. It takes ~7ms on a AMD Athlon MP 2800+ to hexify a 10 million byte array. Is there any trick or other way that I am missing?</p>
<p>How can I make this faster?</p>
<p>Compiled with -O3 in g++</p>
<pre><code>static const char _hex2asciiU_value[256][2] =
{ {'0','0'}, {'0','1'}, /* snip..., */ {'F','E'},{'F','F'} };
std::string char_to_hex( const unsigned char* _pArray, unsigned int _len )
{
std::string str;
str.resize(_len*2);
char* pszHex = &str[0];
const unsigned char* pEnd = _pArray + _len;
clock_t stick, etick;
stick = clock();
for( const unsigned char* pChar = _pArray; pChar != pEnd; pChar++, pszHex += 2 ) {
pszHex[0] = _hex2asciiU_value[*pChar][0];
pszHex[1] = _hex2asciiU_value[*pChar][1];
}
etick = clock();
std::cout << "ticks to hexify " << etick - stick << std::endl;
return str;
}

69,250 | <p>In most C or C++ environments, there is a "debug" mode and a "release" mode compilation.<br>
Looking at the difference between the two, you find that the debug mode adds the debug symbols (often the -g option on lots of compilers) but it also disables most optimizations.<br>
In "release" mode, you usually have all sorts of optimizations turned on.<br>
Why the difference?</p>

<pre><code> 1 to 1st

3 to 3rd
4 to 4th
11 to 11th
101 to 101st
111 to 111th

<p><strong>Solution</strong></p>
<p>Scott Hanselman's answer is the accepted one because it answers the question directly.</p>

69,296 | <p>I have a a property defined as:</p>
<pre><code>[XmlArray("delete", IsNullable = true)]
[XmlArrayItem("contact", typeof(ContactEvent)),

public List<Event> Delete { get; set; }
</code></pre>
<p>If the List<> Delete has no items</p>
<pre><code><delete />
</code></pre>
<p>is emitted. If the List<> Delete is set to null</p>
<pre><code><delete xsi:nil="true" />
</code></pre>
<p>is emitted. Is there a way using attributes to get the delete element not to be emitted if the collection has no items?</p>
<p><a href="https://stackoverflow.com/questions/69296/xml-serialization-and-empty-collections#69407">Greg</a> - Perfect thanks, I didn't even read the IsNullable documentation just assumed it was signalling it as not required.</p>
<p><a href="https://stackoverflow.com/questions/69296/xml-serialization-and-empty-collections#69518">Rob Cooper</a> - I was trying to avoid ISerializable, but Gregs suggestion works. I did run into the problem you outlined in (1), I broke a bunch of code by just returning null if the collection was zero length. To get around this I created a EventsBuilder class (the class I am serializing is called Events) that managed all the lifetime/creation of the underlying objects of the Events class that spits our Events classes for serialization.</p>

<p>Is there a way (on Windows) to track the history of CPU & Memory usage for some process. E.g. I will start tracking "firefox", and after an hour or so will see a graph of its CPU & memory usage during that hour.</p>
