OK, so following on from my question on [XML Serialization and Inherited Types](http://stackoverflow.com/questions/20084/xml-serialization-and-inherited-types), I began integrating that code into my application I am working on, stupidly thinking all will go well..
I ran into problems with a couple of classes I have that implement _IEnumerable_ and _ICollection<T>_
The problem with these is that when the XMLSerializer comes to serialize these, it views them as an external property, and instead of using the property we would like it to (i.e. the one with our _AbstractXmlSerializer_ ) it comes here and falls over (due to the type mismatch), pretty much putting us back to square one.
My current solution is to remove the interface implementation (in this current application, its no real big deal, just made the code prettier).
**Do I need to swallow my pride on this one and accept it cant be done?** I know I have kinda pushed and got more out of the XmlSerializer than what was expected of it :)

Is there a way to tell the browser or OS to let the event through?
For example, on a AdvancedDataGrid I have set the keyUp event to handleCaseListKeyUp(event), which calls the following function:
private function handleCaseListKeyUp(event:KeyboardEvent):void
{
var char:String = String.fromCharCode(event.charCode).toUpperCase();
if (event.ctrlKey && char == "C")
{
trace("Ctrl-C");
copyCasesToClipboard();
return;
}
if (!event.ctrlKey && char == "C")
{
trace("C");
copyCasesToClipboard();
return;
}
// Didn't match event to capture, just drop out.
trace("charCode: " + event.charCode);
trace("char: " + char);
trace("keyCode: " + event.keyCode);
trace("ctrlKey: " + event.ctrlKey);
trace("altKey: " + event.altKey);
trace("shiftKey: " + event.shiftKey);
}
When run, I can never get the release of the "C" key while also pressing the command key (which shows up as KeyboardEvent.ctrlKey). I get the following trace results:
charCode: 0
char:
keyCode: 17
ctrlKey: false
altKey: false
shiftKey: false
As you can see, the only event I can capture is the release of the command key, the release of the "C" key isn't even sent.
Has anyone successfully implemented standard copy and paste keyboard handling?
Am I destined to just use the "C" key on it's own (as shown in the code example) or make a copy button available?
Or do I need to create the listener manually at a higher level and pass the event down into my modular application's guts? | flex | air | null | null | null | null | open | Capturing Cmd-C keyboard event from modular Flex application in browser or AIR.

I also know it's generally not considered a good idea, maybe the worst, to let a browser run and interact with local apps, even in a intranet context.
We use citrix for home-office, and people really like it. Now, they would like the same kind of environment at work, a nice page where every important application/document/folder is nicely arranged and classified in an orderly fashion. These folks are not particularly tech savvy; I don't even consider thinking that they could understand the difference between remote delivered applications and local ones.
So, I've been asked if it's possible. Of course it is, with IE's good ol' ActiveX controls. And I even made a working prototype (that's where it hurts).
But now, I doubt. Isn't it madness to allow such 'dangerous' ActiveX controls, even in the '*local intranet*' zone ? People will use the same browser to surf the web, can I fully trust IE ? Isn't there a risk that Microsoft would just disable those controls in future updates / versions ? What if a website, or any kind of malware, just puts another site in the trust list ? With that extent of control, you could as well uninstall every protection and just run amok 'till you got hanged by the IT dept.
I'm about to confront my superiors with the fact that, even if they saw it is doable, it would be a very bad thing. So i'm desperately in need of good and strong arguments, because "*let's don't*" won't do it.
Of course, if there is nothing to be scared of, that'll be nice too. But I strongly doubt that.. | security | internet-explorer | activex | intranet | null | null | open | Good reasons for not letting the browser launch local applications

I was looking for a way to separate clearly some softwares internals from their representation in c++
I have a generic parameter class (to be later stored in a container) that can contain any kind of value with the the boost::any class
I have a base class (roughly) of this kind (of course there is more stuff)
class Parameter
{
public:
Parameter()
template typename<T> T GetValue() const { return any_cast<T>( _value ); }
template typename<T> void SetValue(const T& value) { _value = value; }
string GetValueAsString() const = 0;
void SetValueFromString(const string& str) const = 0;
private:
boost::any _value;
}
There are two levels of derived classes:
The first level defines the type and the conversion to/from string (for example ParameterInt or ParameterString)
The second level defines the behaviour and the real creators (for example deriving ParameterAnyInt and ParameterLimitedInt from ParameterInt or ParameterFilename from GenericString)
Depending on the real type I would like to add external function or classes that operates depending on the specific parameter type without adding virtual methods to the base class and without doing strange casts
For example I would like to create the proper gui controls depending on parameter types:
Widget* CreateWidget(const Parameter& p)
Of course I cannot understand real Parameter type from this unless I use RTTI or implement it my self (with enum and switch case), but this is not the right OOP design solution, you know.
The classical solution is the Visitor design pattern <http://en.wikipedia.org/wiki/Visitor_pattern>
The problem with this pattern is that I have to know in advance which derived types will be implemented, so (putting together what is written in wikipedia and my code) we'll have sort of:
struct Visitor
{
virtual void visit(ParameterLimitedInt& wheel) = 0;
virtual void visit(ParameterAnyInt& engine) = 0;
virtual void visit(ParameterFilename& body) = 0;
};
Is there any solution to obtain this behaviour in any other way without need to know in advance all the concrete types and without deriving the original visitor?
Thanks for your time

And you can change your code "on the fly" without restarting the serer. As long as your changes don't affect any method signatures or fields you can just hit recompile for a class and the application server (servlet container) will reload the class.
I suppose this is impossible in ASP.NET since all classes are packed into assemblies and you cannot unload/reload assemblies, can you ?
So when you have an .aspx page and an assembly deployed to GAC and your codebehind changes you have to redeploy the assembly and reset IIS. I'm talking about Sharepoint applications in particular and I'm not sure whether you have to do iisreset for private assemblies but I guess you have too.
So the best way to debug aspx pages with code behind I guess would be to get rid of the codebehind for the time of active debugging and move into the page, then when it is more or less working move it back to codebehind. ( This would be applicable only for application pages in Sharepoint, site pages don't allow inline code )
How do you approach debugging of your ASP.NET applications to make it less time consuming?

Assuming that this applies to PHP, Python, Perl, Ruby etc as well as C# (which is what I assume Jeff was using), how much of a slowdown is it and will I incur a similar penalty with "/[a-zA-z]/" as I will with "/[a-z]/i" ?

I didn't want to just dump a bunch of code in the question so I've posted the code for the class on refactormycode.
**[base-class-for-easy-class-property-handling](http://www.refactormycode.com/codes/461-base-class-for-easy-class-property-handling)**
My thought was that people can either post code snippets here or make changes on refactormycode and post links back to their refactorings. I'll make upvotes and accept an answer (assuming there's a clear "winner") based on that.
At any rate, on to the class itself:
I see a lot of debate about getter/setter class methods and is it better to just access simple property variables directly or should every class have explicit get/set methods defined, blah blah blah. I like the idea of having explicit methods in case you have to add more logic later. Then you don't have to modify any code that uses the class. However I hate having a million functions that look like this:
public function getFirstName()
{
return $this->firstName;
}
public function setFirstName($firstName)
{
return $this->firstName;
}
Now I'm sure I'm not the first person to do this (I'm hoping that there's a better way of doing it that someone can suggest to me).
Basically, the PropertyHandler class has a __call magic method. Any methods that come through __call that start with "get" or "set" are then routed to functions that set or retrieve values into an associative array. The key into the array is the name of the calling method **after** get or set. So, if the method coming into __call is "getFirstName", the array key is "FirstName".
I liked using __call because it will automatically take care of the case where the subclass already has a "getFirstName" method defined. My impression (and I may be wrong) is that the __get & __set magic methods don't do that.
So here's an example of how it would work:
class PropTest extends PropertyHandler
{
public function __construct()
{
parent::__construct();
}
}
$props = new PropTest();
$props->setFirstName("Mark");
echo $props->getFirstName();
Notice that PropTest doesn't actually have "setFirstName" or "getFirstName" methods and neither does PropertyHandler. All that's doing is manipulating array values.
The other case would be where your subclass is already extending something else. Since you can't have true multiple inheritance in PHP, you can make your subclass have a PropertyHandler instance as a private variable. You have to add one more function but then things behave in exactly the same way.
class PropTest2
{
private $props;
public function __construct()
{
$this->props = new PropertyHandler();
}
public function __call($method, $arguments)
{
return $this->props->__call($method, $arguments);
}
}
$props2 = new PropTest2();
$props2->setFirstName('Mark');
echo $props2->getFirstName();
Notice how the subclass has a __call method that just passes everything along to the PropertyHandler __call method. | php | oop | null | null | null | null | open | Is this a reasonable way to handle getters/setters in a PHP class?

- constructor syntax: `int(foo)`

Now suppose a few months later that I want to add 3 more fields. And in the future I may add/delete fields from this form based on changing requirements. If I have a database column per form field, then I would have to make the corresponding changes to the database each time I change the form. This seems like a maintenance headache. There must be a more sophisticated way.
So my question is, how do I design a data model that is loosely coupled with my UI? A concrete use case is a CRM system that is extensible/customizable by users.

For example, assuming an empty database (pseudo code):

user1.firstName = "Allain" // alters the table to have a firstName column as varchar(255)
user2 = new User() // Reuses the table
user2.firstName = "Bob"
user2.lastName = "Loblaw" // Alters the table to have a last name column
Since there are logical assumptions that can be made when dynamically creating the schema, and you could always override its choices by using your DB tools to tweak it later.
Also, you could generate your schema by unit testing it this way.
And obviously this is only for prototyping.

We have a website, lets call it finalcog.com. It's a UK-based site, with UK based content. Google knows about it, and we have done a load of SEO on it. All is well.
**Except**, we are about to relaunch **final cog, the GLOBAL brand**, so we now need finalcog.com/uk, finalcog.com/us, and finalcog.com/au, for the various countries local content. We are using GEOIP, so if someone from the US loads finalcog.com, they get redirected to finalcog.com/us etc.
If someone isn't in one of those three countries (US, Australia, or UK) they get the UK site.
This is all well and good, but we dont want to loose the rather large amount of google juice we have on finalcog.com! And worse, the google bot appears to be 100% based in the US, so the US site (which is pretty much out LEAST important one of the three) will appear to be the main one.
**We have thought about detecting the bot**, and serving UK content, but it appears google may smack us for that.
Has anyone else come across this situation, and have a solution?

I prefer the [assertions](http://java.sun.com/j2se/1.4.2/docs/guide/lang/assert.html) approach, but I don't like the fact that assertions are turned off by default.
The book finally states:

It doesn't really go into how you would enforce this restriction?
Do any of you have strong opinions either way.

Don't get me wrong, I'm all for doing everything possible to protect people's personal information (health, financial, surfing habits, etc.), but sometimes people get a little too jumpy.
Case in point: One of our state customers recently found out that the browser provides the handy feature to save your password. We all know that it has been there for a while and is completely optional and is up to the end user to decide whether or not it is a smart decision to use or not. However, there is a bit of an uproar at the moment and we are being demanded to find a way to disable that functionality for our site.
Question: Is there a way for a site to tell the browser not to offer to remember passwords? I've been around web development a long time but don't know that I have come across that before.
Any help is appreciated.
Thanks,
Matt

Specifically, when writing a test that is meant to be used by anyone including QA staff, should the steps in the test be very specific or more broad giving the tester more leeway in how the task can be accomplished. As a very simple example, if you're testing opening a document in word processing document, should the test read:
1. Using the mouse, open the file menu
2. Choose "Open File..." in the file menu
3. In the open file dialog that appears, navigate to x and double-click the document called y
OR
1. Bring up the file open dialog
2. Open the file y
Now I realize one answer is probably going to be "it depends on what you're trying to test" but I'm trying to answer a broader question here: If the test steps are too specific do we risk a) making the testing process to laborious and tedious and more importantly b) do we risk missing something because we wrote down too specific a path to achieve a goal. Alternatively, if we make it broad do we depend too much on the whims of the tester at the time and lose crucial testing of paths that are more common to customers/clients?

A Google search of the URL indicates that it's from email spammers based out of Romania or China, but that's not what's important right now.

Obviously there's more that needs to be done (hardening the site against SQL injections, using something like markdown instead of storing HTML, etc.) and I am working on those but for the time being what I really need is a good way to go in and programmatically remove the injected text. I know what the exact text is, it's the same every time, and it's always appended to the end of any text field.

That being said, one issue we are running into is that after we push out an update with new JavaScript files, the client browsers still use the cached version of the file and they do not see the update. Obviously, on a support call, we can simply inform them to do a ctrl-F5 refresh to ensure that they get the up-to-date files from the server, but it would be preferable to handle this before that time.
Our current thought is to simply attach a version number onto the name of the JavaScript files and then when changes are made, increment the version on the script and update all references. This definitely gets the job done, but updating the references on each release could get cumbersome.
As I'm sure we're not the first ones to deal with this, I figured I would throw it out to the community. How are you ensuring clients update their cache when you update your code? If you're using the method described above, are you using a process that simplifies the change?

- If I am testing an exception, random values will not ensure that the test ends up in the expected state

I've got items that are tagged and I want to associate those items with photos from Flickr. Even with restrictive searches I might get results numbering in the thousands.
Requirements:
1. I want to display between 10-20
pictures but I want to randomize the
photos each time.
2. I don't want to hit Flickr every
time a page request is made.
3. Not every Flickr photo with the same
tags as my item will be relevant.
The question is, How should I store that number of results and how would I determine which ones are relevant? | php | tags | flickr | null | null | null | open | Pulling limited tagged photos from Flickr

Even though I'm not the worlds worst artist, it's discouraging to see the results from a professional designer, who can do an amazing mockup from a simple spec in just a few hours. I always wonder how they came up with their design and more importantly, how they executed it so quickly.
I'd like to think that all good artists aren't naturally gifted. I'm guessing that a lot of skill/talent comes from just putting in the time.
Is there a recommended path to right brain nirvana for someone starting from scratch, a little later in life? I'd be interested in book recommendations, personal theories, or anything else that may shed some light on the best path to take. I have questions like should I read books about color theory, should I draw any chance I have, should I analyze shapes like an architect, etc...
As far as my current skills go, I can make my way around Photoshop enough where I can do simple image manipulation...

One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen. [Notepad++][2], my preferred Notepad replacement, also does this.
Another neat and similar feature in Eclipse was the vertical "error bar" to the right of your code (not sure what to call it). It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like "variable declared but not used", and if you select a word, boxes appear in the bar for each occurance of the word in the document.
A screenshot of these features in action:
![screenshot][3]
After a half hour of searching, I've determined that Visual Studio cannot do this on its own, so my question is: does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features?
Being able to highlight the current line your cursor is on would be nice too. I believe the add-in ReSharper can do this, but I'd prefer to use a free add-in rather than purchase one.

Each time one of the items updates its JProgressBar, the ListDataListener on the list tries to scroll it the visible range using
/*
* This makes the updating content item automatically scroll

Note that I'm trying to make sure the scrolling is done in the dispatch thread, since I thought maybe the problem was it being scrolled while it was repainting. And yet, I still have a problem where if things are really active, some of the list items paint outside of the viewport, overwriting what's outside the JScrollPane. Forcing an exposure event will repaint those things, but it's annoying.
Is there anything else I need to look out for to stop these things painting outside of their clipping area?
