How do I find if a string contains HTML data or not? The user provides input via rich:editor component and it's quite possible he could have used either a simple text or used HTML formatting.
After code like this:
$stmt = $mysqli->prepare("SELECT District FROM City WHERE Name=?")) {
$stmt->bind_param("s", $city);
$stmt->execute();
$stmt->bind_result($district);
$stmt->fetch();
printf("%s is in district %s\n", $city, $district);
How Do I See The Actual SQL Statement That Was Executed?

I am looking for a tool for building static template-based web sites, your typical brochure-ware for a non-profit or a personal site.
I have used CityDesk, but that is out-of-date, unsupported, and has certain problems.
Of course there are lots of tools out there, but I cannot find anything similar to CityDesk:
WYSIWYG as well as HTML…
I would like to work out a number's factorial. My factorial rule is in a Prolog file and I am connecting it to a C++ code. Can someone tell me what is wrong with my C++ interface please?
% factorial.pl
factorial( 1, 1 ):-
!.
factorial( X, Fac ):-
X > 1,
Y is X - 1,
factorial( Y, New_Fac ),
Fac is X * New_Fac.

Instead of populating the BitmapData class from an IMAGE. I would like to (within Actionscript) GENERATE some new BitmapData by capturing the Bitmap representing say, a TextArea component on the stage.
In other words, sort of take a "screen capture" or "screenshot" of one of the components, and convert that into an image. Am I silly to…
I'm sure everyone knows the joys of concurrency when it comes to threading.
Imagine the following scenario on every page-load on a noobily set up MySQL db:
UPDATE stats SET visits = (visits+1)
If a thousand users load the page at same time, will the count screw up? is this that table locking/row locking crap? Which one mysql use.
I have JDBC driver dependencies (e.g. h2, mysql ..) which have to be copied under ${jboss.home}/common/lib before it is used by my EAR application. What would be the best way to directly copy from a maven repository into the above location instead of doing a manual copy. I would not prefer to store copies of the drivers as part of my SVN.…
Does anyone know why including a term such as:
t = PL_new_term_ref();
would cause an Unhandled Exception error message:

So here's my problem: I have two types of registration, registration A and registration B, each will have some of the same fields and some different fields. I was going to create abstract class registration and both A and B would have their own classes that extend from registration. My question is, should I create a seperate Validation…
When I push a view controller it animates properly and slides in, the only problem is that no 'Back' button is rendered up top.The back button is still there, I can still tap it, it just doesn't render on the screen.
This behavior is identical in both the simulator and on multiple devices.
Is this a known issue or bug? Using 3.1.3 of…
I am trying to emulate a web browser in order to execute JavaScript code and then parse the DOM. The System.Windows.Forms.WebBrowser object does not give me the functionality I need. It let's me set the headers, but you cannot set the proxy or clear cookies. Well you can, but it is not ideal and messes with IE's settings.
I've been…
C++ is clearly a far superior language than C, since it has many features that C lacks (although, C++'s object model isn't as ideal as say C#'s). With the coming off the new C++0x standard, why hasn't C been phased out to obscurity?
C++ has been around for so long, since the '80s. The Linux kernel has already been ported to C++ with…
I want to view the actual SQL resulting from a php call to mysqli-prepare, and apparently the only way to do that is by logging all queries. However, I can't seem to manage to turn on query logging in mysql for windows.
Help?
Without purchasing someone elses software, how can I as a software engineer, delete index.dat? What OS Voodoo hoops do I have to jump through to accomplish the simple deletion of a single file on my own computer? I have windows Vista.
I've been looking for ways to learn about the right way to manage a software project, and I've stumbled upon the following blog post. I've learned some of the things mentioned the hard way, others make sense, and yet others are still unclear to me.
To sum up, the author lists a bunch of features of a project and how much those…
If I want to know if an object has a particular property I can code this:
if (SomeObject.hasOwnProperty('xyz')) {
// some code
}
But some styles masquerade as properties at design time such as Button.color... How can I know what style properties are valid at runtime? ie: What is the equivalent of hasOwnProperty for…

What possible basic approaches could be taken in an effort to create a Flex component that could run Java?
I know I can easily use flex to browse to or launch a Java app, but there are things I can only do if I can run the Java from WITHIN an MXML Component.

What is the opposite of String.charAt()??
If I Have a string:
var Str:String="Hello World";
How do I change the 5th character, for example, from a ' ' to an '_'?
I can GET the 5th character like this:
var C:String=Str.charAt(5);
But how do I SET the 5th character?
Thanks in advance.
I'm pretty sure I've included the qanda class, but when I try to declare a vector that contains it or a class of that type I get an error saying that qanda is undefined. Any idea what the problem might be?

If the bisect range includes multiple branches, how does hg bisect's search work. Does it effectively bisect each sub-branch (I would think that would be inefficient)?
For instance, borrowing, with gratitude, a diagram from an answer to this related question, what if the bisect got to changeset 7 on the…
I have 3 top level entities in my app: Circuit, Issue, Document
Circuits can contain Documents and Issues can contain Documents.
When I delete a Circuit, I want it to delete the documents associated with it, unless it is used by something else. I would like this same behavior with Issues. I have it…
