When I use PDO::prepare() to build a certain query, then pass parameters to execute, the query will execute correctly but one of the parameters does not seem to be inserted into the database. The prepare statement looks like this:
... SET col = :par1-:par2 ...
So what I'm trying to do is put the value "[par1]-[par2]" into the column in the database. The problem is that the first parameter is not being stored in the database, but the dash and the second parameter are. So the resulting value being stored in the database from the above query is "-[par2]".
Why would that be? | php | mysql | query | pdo | null | null | open | Two parameters right next to each other in a PDO query?

(The server reads the file, augments it with some extra information, and serves up the modified content transparently to the person viewing the page.)
Unfortunately, when I did this, welcome-files stopped working. Previously, if I typed in the URL for a directory, the server would look for index.html and serve up that. Now, I'm just getting a 403 forbidden rule ("Forbidden - by rule."). The access logs don't show anything more--they simply state that directory indexing is forbidden by rule for the server, which is correct. I don't want the webserver to build a table of contents for directories with no index.html, but when there is an index.html, I want it to serve up that file.
My first thought was that it was trying to serve the index.html through my servlet, the servlet was failing to find the file (because the url lacked "index.html"), and therefore it thought there was no index.html. However, I put in some debug code and am quite confident that the servlet code is never getting run when I go simply to the directory itself.
I don't really care whether index.html is served through the servlet or not--in the case of this particular file, the servlet would just spit back the original file anyway. I just want index.html to be served by something.
Here is the relevant section of my web.xml
<servlet-mapping>
<servlet-name>PageScrubber</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
For what it's worth, index.htm and index.jsp were not working before the addition of the servlet mapping. Only index.html worked before. However, now none of them work.
I have used the same web.xml with two Oracle products: WebLogic (WLS) and Oracle Application Server (OAS) with no issues.
I am quite confident that it is just the addition of this scrubber servlet that has caused the problem, because removing that directive caused directory indexing to start working again.
I did find some notes about welcome-file-list not working when using an extended document root, and I tried setting com.ibm.ws.webcontainer.EnablePartialURLtoExtendedDocumentRoot to be true, but that did not seem to change anything.
I'm pretty much out of ideas. Does anyone out there have any thoughts as to why it's not finding my index.html? Thanks in advance! | websphere | web.xml | null | null | null | null | open | Websphere not using welcome-file-list after mapping *.html to a servlet

I've implemented an abstraction of configuration data (_i.e._ web.config) in an interface:
interface IConfigurationProvider
{ ... }
along with implementations for ASP.NET (`WebConfigurationProvider`) and "desktop" applications (`ExeConfigurationProvider`).
Some of my autofac modules then require an `IConfigurationProvider` as a constructor parameter, but some don't:
class DependentModule : Module
{
public DependentModule(IConfigurationProvider config)
{
_config = config;
}
protected override void Load(ContainerBuilder builder)
{
builder.RegisterType(_config.TypeFromConfig);
}
private readonly IConfigurationProvider _config;
}
class IndependentModule : Module
{
protected override void Load(ContainerBuilder builder)
{
builder.Register(/* other stuff not based on configuration */);
}
}
Since the `RegisterType()` extension method doesn't accept a registration delegate (`Func<IComponentContext, T>`), like `Register()` does, I can't register the `IConfigurationProvider` up-front and then resolve it when I go to register the type specified in the configuration, something like:
// this would be nice...
builder.RegisterType(c => c.Resolve<IConfigurationProvider>().TypeFromConfig);
This means that I need to be able to register modules **with and without** a dependency on `IConfigurationProvider`.
It's obvious how to manually instantiate each module and register it:
IConfigurationProvider configProvider = ...;
var builder = new ContainerBuilder();
builder.RegisterModule(new DependentModule(configProvider));
builder.RegisterModule(new IndependentModule());
using (var container = builder.Build())
{
...
}
But I don't want to manually instantiate my modules - I want to scan assemblies for modules and register them automatically (as discussed [in this question](http://stackoverflow.com/questions/10018831/autofac-module-scanning-for-various-applications)). So I have to use reflection to scan the assembly for `IModule` types, and use `Activator.CreateInstance` to make registerable instances. But how do I know whether or not to pass an `IConfigurationProvider` as a constructor parameter. And what happens when other modules have additional or different dependencies?
There's got to be a more straightforward way of accomplishing the basic task: register a type specified in some configuration provided via an interface, right? So how do I do that? | autofac | autofac-scanning | null | null | null | null | open | Autofac modules with their own dependencies

My mysql DB has become CPU hungry trying to execute a particularly slow query. When I do an explain, mysql says "Using where; Using temporary; Using filesort". Please help deciphering and solving this puzzle.
Table structure:
CREATE TABLE `topsources` (
`USER_ID` varchar(255) NOT NULL,
`UPDATED_TIME` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`URL_ID` int(11) NOT NULL,
`SOURCE_SLUG` varchar(100) NOT NULL,
`FEED_PAGE_URL` varchar(255) NOT NULL,
`CATEGORY_SLUG` varchar(100) NOT NULL,
`REFERRER` varchar(2048) DEFAULT NULL,
PRIMARY KEY (`USER_ID`,`DATE_AND_HOUR`(30),`ITEM_ID`),
KEY `USER_ID` (`USER_ID`),
KEY `FEED_PAGE_URL` (`FEED_PAGE_URL`),
KEY `SOURCE_SLUG` (`SOURCE_SLUG`),
KEY `CATEGORY_SLUG` (`CATEGORY_SLUG`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
The table has 370K rows...sometimes higher. The below query takes 10+ seconds.
SELECT topsources.SOURCE_SLUG, COUNT(topsources.SOURCE_SLUG) AS VIEW_COUNT FROM topsources WHERE CATEGORY_SLUG = '/newssource' GROUP BY topsources.SOURCE_SLUG HAVING MAX(CASE WHEN topsources.USER_ID = 'xxxx' THEN 1 ELSE 0 END) = 0 ORDER BY VIEW_COUNT DESC;

When someone clicks the drilldown icon on that Person, a subreport displays some more data pertinent to that Person.

I've tried setting the visibility of the subreport to Hide initially, then Show when the user drills down, but it didn't change anything.

I chose the `Posix` implementation , meaning , I used the following calls :
mmap()
shm_open()
ftruncate()
shm_unlink()
For semaphores and synchronization
sem_init()
sem_getvalue()
sem_wait()
sem_post()
(I might forgot one or two calls)
My TA told me that he prefers that I'd implement that library with `System V` version ,
however since I'm in the middle of my exams , I have no extra time to do that (would take a least a week , I guess) .
My questions are :
1. What's is the difference between a pipe that's implemented in Posix vs a pipe that's implemented in System-V ?
2. What calls would I need for implementing the above library using the `Sys V` version ?
Thanks

now i want to retrieve all the hotels which match ALL facilities asked for

is there any workaround or solution for this?

Now matter what I try though I simply cannot reproduce the results from this [A List Apart: Taming Lists][1] article. In the linked to example the list is exactly how I'd like to style mine.
I have reproduced the example in a JS Fiddle here which shows the issue of the misaligned text: http://jsfiddle.net/jannis/f8TxN/
Here is also a quick image to illustrate this point better. Example from ALA on the left, my version on the right:
![List Misalignment][2]
However as you will be able to see in the Fiddle, the first line within the `li` simply will not align left with the rest of the text within this `li`.
I would really appreciate someone taking a look and telling me what I'm doing wrong here.

How can I let my customers have their own domains redirect to my server and identify them? Like Wordpress.
For example, I have created a simple CMS system and customers can register and have their own pages like john.mysite.com. But if they want to use their domains, do I have to create all of those domains on Plesk? By the way, I'm using IIS 7.5 with Plesk.
I also don't want to use iframe.
Example;
> john.mywebsite.com/categories-150.html -->
> www.johnswebsite.com/categories-150.html
But it should be using the same code. I shouldn't have to copy all the source codes and create seperate domains for this purpose.
For sure, I can make them change their ns to my server and specify an A record but how can I identify it by code? (C# ASP.NET MVC) I assume I can search for the domain name over database and get the ID but how can I pass the domain name?
I hope you can understand :)
Thanks and regards

| php | api | tags | html-parsing | translation | null | open | temporary remove Html from string for google api translation to save dollars
===
I have to translate some details using google API which is now paid.Details also contains HTML and google charge for each character, so i dont want to send complete content but only English text, removing html. I can remove html tags and entities using PHP functions , but I have to place english content back in HTML tags after translation for proper display. It will also include CSS.
Example
<strong>This is a test</strong><br /> <custom tag>This is a test</custom tag><br />
After translation to Spanish I need
<strong>Translated content </strong><br /> <p>Translated content </p><br />

The reason for this is that people will be able to access URLs provided they have the link to the content however they should not be able to get at other content by substituting the article id in the URL (i.e: index.php/category/1, index.php/category/2). Regardless of alias text placing the article id onto the url with url rewriting enabled will access the article. I am using the K2 component so would be applying this to K2 articles (Items).
I had thought about hard coding the alias to a random value on article creation but this won't solve the issue. Even a way of obfuscating the URL should work, although the plugins I tried for Joomla only do external links.
Any ideas?

Is there a way to specify that I only want to mirror the canonical forms?
If not, could someone please tell me if and HOW to modify the repository once it's been downloaded? My idea is to delete the pack200 files manually and then regenerate the metadata. I'm guessing with `org.eclipse.equinox.p2.publisher.FeaturesAndBundlesPublisher`?

I have no say over this practice or the format of the config file.
I want to do EntLib exception logging to the database in this setting. I therefore need to set up a EntLib database configuration instance with the name of the database, with the connection string. Since I can't get the connection string until run time, but EntLib does allow run-time configuration, I use the following code, as described in [this][1]:
builder.ConfigureData()
.ForDatabaseNamed("Ann")
.ThatIs.ASqlDatabase()
.WithConnectionString(connectionString)
.AsDefault();
The parameter `connectionString` is the one I've retrieved from the separate library.
The sample code goes on to merge the created configuration info with an empty DictionaryConfigurationSource. I, however, need to merge it with the rest of the configuration code from the app.config. So I do this:
var configSource = new SystemConfigurationSource();
builder.UpdateConfigurationWithReplace(configSource);
EnterpriseLibraryContainer.Current
= EnterpriseLibraryContainer.CreateDefaultContainer(configSource);
... which is based very closely on the sample code.
But: I get an internal error in Microsoft.Practices.EnterpriseLibrary.Common.Configuration.SystemConfigurationSource.Save. The failing code is this:
var fileMap = new ExeConfigurationFileMap { ExeConfigFilename = ConfigurationFilePath };
var config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
config.Sections.Remove(section);
config.Sections.Add(section, configurationSection);
config.Save();
... where 'section' is "connectionStrings". The code fails on the Add method call, saying that you can't add a duplicate section. Inspection shows that the connectionStrings section is still there even after the Remove.
I know from experience that there's always a default entry under connectionStrings when the configuration files are actually read and interpreted, inherited from the machine.config. So perhaps you can never really remove the connectionStrings section.
That would appear to leave me out of luck, though, unless I want to modify the EntLib source, which I do not.
I could perhaps build all the configuration information for the EntLib at run time, using the fluent API. But I'd rather not. The users want their Operations staff to be able to make small changes to the logging without having to involve a developer.
So my question, in several parts: is there a nice simple workaround for this? Does it require a change to the EntLib source? Or have I missed something really simple that would do away with the problem?
Many thanks.

So, devise is already setting the `Set-Cookie` header with the response when I success login, but my client side is not setting those cookies. I dont think is a CORS problem and even a configuration with rails sessions, because the domain is already set to match all subdomains also `.myapp.dev`

===
i am using this slideshow made with html and javascript:
http://tympanus.net/codrops/2011/09/20/responsive-image-gallery/
the slideshow works good hovewer the large images are not clickable. It has the <a href> property but how to make them work so when i click to a picture to send me to the specific link (the link that i write in href="")
it gets the values from this:
<div class="es-carousel">
<ul>
<li><a href="http://www.google.com"><img src="images/cityPlaces_images/thumbs/1.jpg" data-large="images/cityPlaces_images/1.jpg" alt="image01" data-description="From off a hill whose concave womb reworded" /></a></li>
and it generates in this gallery.js:
var $thumb = $item.find('img'),
largesrc = $thumb.data('large'),
title = $thumb.data('description');
$('<img/>').load( function() {
$rgGallery.find('div.rg-image').empty().append('<img src="' + largesrc + '"/>');
if( title )
$rgGallery.find('div.rg-caption').show().children('p').empty().text( title );

As the projects I develop have become more complex, there are many more records in the database and, as a result, greater likelihood of memory issues.
I'm getting the PHP error `Allowed memory size of 67108864 bytes exhausted` when looping through a mySQL result set and was wondering whether there was a better way to achieve the flexibility I have without the high memory usage.
My function looks like this:
function get_resultset($query) {
$resultset = array();
if (!($result = mysql_unbuffered_query($query))) {
$men = mysql_errno();
$mem = mysql_error();
echo ('<h4>' . $query . ' ' . $men . ' ' . $mem . '</h4>');
exit;
} else {
$xx = 0 ;
while ( $row = mysql_fetch_array ($result) ) {
$resultset[$xx] = $row;
$xx++ ;
}
mysql_free_result($result);
return $resultset;
}
}
I can then write a query and use the function to get all results, e.g.:
$query = 'SELECT * FROM `members`';
$resultset = get_resultset($query);
I can then loop through the `$resultset` and display the results, e.g.:
$total_results = count($resultset);
for($i=0;$i<$total_results;$i++) {
$record = $resultset[$i];
$firstname = $record['firstname'];
$lastname = $record['lastname'];
// etc, etc display in a table, or whatever
}
Is there a better way of looping through results while still having access to each record's properties for displaying the result list? I've been searching around for people having similar issues and the answers given don't seem to suit my situation or are a little vague. Any help would be greatly appreciated.

public static final String componentName = "DSSCOMMasterLib.IDSSObjectInfo";
public IDSSObjectInfo() {
super(componentName);
}
}
public class IDSSFolder extends Dispatch {
public static final String componentName = "DSSCOMMasterLib.IDSSFolder";
public IDSSFolder() {
super(componentName);
}
public IDSSFolder(Dispatch d) {
// take over the IDispatch pointer
m_pDispatch = d.m_pDispatch;
// null out the input's pointer
d.m_pDispatch = 0;
}
public IDSSFolder findTypedObjects(int objectType, int flags) {
return new IDSSFolder(Dispatch.call(this, "FindTypedObjects", new Variant(objectType), new Variant(flags)).toDispatch());
}
}
Any help will be greatly appreciated. Thanks!

I had originally indexed every field as string. Once I changed it and indexed the numbers as integers they didn't display in the output. I completely guess and went with int since I indexed them as integers and it worked. ;)
Here are the data types I'm indexing the latitude and longitude with in Solr:
<field name="lat" type="latLongDouble" indexed="true" stored="true"/>
<field name="lng" type="latLongDouble" indexed="true" stored="true"/>
I am not sure of any of the proper XSL datatypes that can be used for the "???" above.
1. Can you provide me a list of these to try out?
2. Can you provide me an alternative XSL method to display the output?
Many thanks!

the following HTML code belongs to the 'td' that contains the 'Password':

passwordChanged is a javascript function to determine the strength of the password. This function changes the innerHTML of the span 'strengthID'
My problem is simple: when 'stengthID' changes its content (on onkeyup event), the whole table shifts left.

My goal is to keep everything as it is while changing the inner text of the span. I couldn't get rid of this behavior. Please can you point to some possible css attribute I would need to use? or any other suggestions?

(<5 seconds) | I am looking at Android for a project (in car entertainment*) in which power consumption, especially when not in use, is a great concern, but the environment is tightly controlled and *predictable*.
The problem however is that Android has no hibernate mode, and is pretty liberal with allowing Apps processor cycles in standby making it hard to gauge power consumption when the device is not in use and so I would like to shut it down entirely when not needed, which means it needs to boot ***fast***.
I know many Linux variants have achieved [very quick boot times][1] and less than 10 seconds on some could be considered standard. I have also [read about Androids long boot times][2] and it seems a lot of the delays in loading, like on any OS, could be considered optional?
For example, the presentation states that
> "Android can boot without preloading any classes"
and that this
> "can result in bad application load times and memory usage later"
But this is not a concern as long as it is deterministic - if you can find which classes an MP3 player required for example, and turned off all the others and gained 10 seconds it doesn't matter that other apps would take 20 seconds to load because it will never load them.
The same thing goes for the network stack which wouldn't be needed, and for many of the packages, certificate checking, etc.
I know 50 seconds to 5 seconds is a **very** tall order, but is there any reason it is not doable?
Has anyone attempted something like it before? Is Android customizable enough to allow this?
**If Android were to be "streamlined" enough, could it boot in 5 seconds?**
EDIT: The hardware this would be targetting would be 'embedded PC level': think http://store.tinygreenpc.com/tiny-green-pcs/trim-slice/h-diskless.html

Anyway...here goes.
I followed a tutorial on YouTube about parsing XML in iOS. Works great. However, the tutorial parses the XML into labels. That part works perfectly. However, I'm attempting to parse a podcast RSS feed, using a custom made XML document, and I'd like the link to the video to go to a button that plays, rather than fill a label. So I assumed I could pass the link that's already working into a button that uses the MPMoviePlayerViewController. Didn't work.

===
So I'm extremely new to coding in general (my background is in video production) and I've been tasked with creating an iPhone app. Xcode has actually been pretty easy with tutorials and the like, but I've run into a brick wall of things outside of my knowledge. Anyway...here goes.
I followed a tutorial on YouTube about parsing XML in iOS. Works great. However, the tutorial parses the XML into labels. That part works perfectly. However, I'm attempting to parse a podcast RSS feed, using a custom made XML document, and I'd like the link to the video to go to a button that plays, rather than fill a label. So I assumed I could pass the link that's already working into a button that uses the MPMoviePlayerViewController. Didn't work.

How do I alter the about-to-occur-find-operation that is about to take place, inside beforeFind()? Messing with '$this' attributes is not useful since its not even populated, which is a little surprise.
I've seen the documentation mentions a "hidden CDbCriteria parameter" but I just couldn't guess how to use it... . Unfortunately, the documentation on this subject is slim.

I have a DataGrid bound to a collection of POCOs, which implement INotifyPropertyChanged interface and fire PropertyChanged events. One of the properties is a double value, let's call it Price.
###Goal:
When Price goes up, DataGrid cell displaying it should blink green, when it goes down it should blink red. By blink I mean change background color for certain (small) amount of time.
###Problem:
I'm unable to achieve this, have tried using data triggers with specially added properties in the data object (eg. PriceUp and PriceDown), but the problem is when and how to reset these flags to false, so that subsequent change would again run the trigger. Pulsing the flag false then true on update doesn't work. EventTrigger (on TargetUpdated) is of no help either, as far as I can tell, since I can't combine it with data conditions.

This HTML form contains a login for both free and paid users. Paid users need to enter a username and password, while free users have to enter default usernames e.g. Username = myname, and Password = password.
I managed to auto populate the values of the form using an HTML link -
<a href="#" onclick="document.getElementById('name').value='myname';document.getElementById('password').value='mypassword';" >Free User</a>
This worked smoothly. Now I would like to add the possibility that when the Free User clicks the button, the values are auto populated as above and the said HTML form is submitted immediately.
When I tried it using various methods, the fields would populate but the HTML form will not submit.
Thanks you.
