Does this code look right
<?php
$name=$_POST['name'];
$email=$_POST['email'];
$location=$_POST['location'];
mysql_connect("your.hostaddress.com", "username", "password") or die(mysql_error());
mysql_select_db("Database_Name") or die(mysql_error());
mysql_query("INSERT INTO `data` VALUES ('$name', '$email', '$location')");
Print "Your information has been successfully added to the database.";
?>
What colors? You mean in code view?
Actually your last line should be this -
print ("Your information has been successfully added to the database.");
Other than that, the code and its coloring are correct as far as I can tell.

Programming project: does this code look clean enough to turn in?
Hi, i was just wanting to know people's opinion on the format of my classes below, i haven't done much java programming and I just want to make sure that this program is easily understood. I will not be able to respond, because I have to wake up in 3 hours for school. So thanks in advance, I will be reading this tomorrow, to see your suggestions, thank you.
here is the scholar class, it is the class that i made to create a scholar(student object) that will be applying for a scholarship and the grades are entered in the ScholarTester class.
I could've done things differently and easier but the professor strictly called for it to be exactly as he stated. I came up with a better, less tedious way, but i couldn't use it. My way was to create a method to randomly generate grades and values to determine the major, but my prof. saw it and made me implement everything in ScholarTester. Also neither of the students will receive the scholarship, that will be determined in project 2 my professor said.

}Thanks for reading this long and boring project.On comments: don't include a comment that just repeats syntax:
// constructor for a Scholar object
public Scholar(String myFullName, ...Anyone knowing Java syntax doesn't need that comment and gains nothing
from its presence, and anyone not knowing Java syntax shouldn't be reading
a listing.
On parameter names: a isn't very imaginative or prescriptive. (See next code.)
On setters returning the argument:
public int setCreditHours(int creditHours ){
this.creditHours = creditHours ;
return creditHours;
}1. Most people keep it simple and use a void return type.
2, The next most common convention is to return this:
public Scholar setCreditHours(int creditHours){
this.creditHours = creditHours ;
return this;
}Then you can chain calls, which is occasionally useful:
scholar.setCreditHours(4).setEssayScore(2);3. If you insist on returning the argument, note that this is a one-liner:
public in setCreditHours(int creditHours){
return this.creditHours = creditHours ;

Hi there,
I have just tried to sync my iphone.
Worryingly an error message saying it cannot be synced has popped up quoting error code (-50)
I have just removed old iphone backups from itunes but was very careful to not delete the current one

What does " this code must be redeemed in the Australian storefront " mean? And how can I fix it?
What does " this code must be redeemed in the Australian storefront " mean? And can I fix it?
All iTunes gifts and gift cards are country-specific, they can only be redeemed and used in their country of issue. Are you in Australia with an Australian billing address on your account ? If you are then try going to the bottom of the Featured tab in the App Store app on your iPad and tap on your account id, tap on 'View Apple ID' on the popup and log into your account, and then select the Country/Region section and select Australia.
If you are not in Australia then you won't be able to use it. -
Simple Question: Why does this code not exit properly?
This code is pretty simple. All I want to do is load and play a sound file in an application, but this code to load the sound file does not exit properly. I know that some resources must be allocated which I need to deallocate in order to shut down the process, but I don't know what to call to do a proper shut-down. Any help would be appreciated.
-adam
import java.applet.Applet;
import java.applet.AudioClip;
import java.net.MalformedURLException;
import java.net.URL;
public class PlaySoundTest extends java.applet.Applet
public static void main( java.lang.String[ ] aryArgs )

catch( java.net.MalformedURLException murle )
murle.printStackTrace( );
System.exit( 1 );
java.applet.AudioClip acSound = java.applet.Applet.newAudioClip( urlSound );HI , If u'r still looking for the solution, this code is working on my system -
import java.applet.Applet;
import java.applet.AudioClip;
import java.net.MalformedURLException;
import java.net.URL;
public class PlaySoundTest extends java.applet.Applet
public static void main( java.lang.String[ ] aryArgs ){

try{ //rahul
try
urlSound = new java.net.URL( "file:" + aryArgs[ 0 ] );
catch( java.net.MalformedURLException murle )
murle.printStackTrace( );
System.exit( 1 );
urlSound = new java.net.URL( "file:" + aryArgs[ 0 ] );
java.applet.AudioClip acSound = java.applet.Applet.newAudioClip( urlSound );
if(acSound != null){
acSound.play();
catch( Exception murle )
{ //rahul
murle.printStackTrace( );
System.exit( 1 );
}//main
The only change I made was in the URL part - file: instead of file:/ .
The other was of course to play the soundclip ...... :- ) I got really confused the first time I played it . -
Does this code effect performance.
I am doing some code now :) and I did a method like this, however I do not know if it effects performance for the whole application when the method is being called, or weather it is a good coding standard.
The code in question is the following:
public void myMethid(){
class c{
public c(String s){
System.out.println(s);
c myC = new c("Hello");
}I know this is a stupid example, however would such a think effect performance, or be wrong? ... would it be better to just declare c as an external class?
regards,
sim085I have seen ppl complaining about cross posts, but what I am going to do here is cross post my answer, which I feel might be helpful in this situation, and considering that it still lies in the grey area:-
"I smell a very interesting discussion stemming out of it, but your question is as open ended as it could be, what kind of web application and what performance. performance is the most misused word I have come across in a lot of design considerations. It is not one parameter you could measure but a combination of different considerations, which would be as follows:-
1) Response time
2) Responsivesness
3) Latency
4) Thoroughput
5) Load
6) Load sensitivity
7) Efficiency
8) capacity
9) scalabilty
You might want to look on the web as to what they mean since I am not going to go into that detail. But these attributes are independent of each other, an application with good latency might be poor in scalability or other way around, so it depends as to whats the nature and requirements of the app you are looking at then deciding which way you would want to go. Its not that simple.
Secondly I would quote Martin Fowler from his book "Patterns of Enterprise Application Architecture":-
"Too often I have seen designs used or rejected because of performance considerations, which turn out to be bogus once somebody actually does some measurements on the real setup used for the application."
So please go back to the requirements and try to figure out what you are actually looking for." -

ENDMETHOD.r_htkl must be a range table. check the declaration part of it.
p_htkl is a parameter on selection screen i hope.
so, there are four fields on a range table.(range table are similar to your select options)
1. SIGN ( I or E - Inclusive or Exculsive)
2. OPTION(options like EQ = euqal, BT = Between, CP = contains pattern etc)
3. LOW (value)
4. HIGH (value)
so..
IF NOT p_htkl IS INITIAL. " checks if some thing is being passed to the parameter
r_htkl-sign='I'. " give the sign a value I i.e it make inclusive sign
r_htkl-option='EQ'. " EQ to option means you value will be checked for a equal to condition
r_htkl-low=p_htkl. " the low field in now assigned the same value of the parameter p_hktl
APPEND r_htkl. " the range table is appended.
endif.
so this range table can be used in select statements as :
select * from abcd into gt where xyz in r_hktl. ==> this will check for a EQ condition with value in r_hktl-low in database or
in if statements like : if abc in r_hktl. ==> this will check the EQ condition of abc with the r_hktl-low.
Had it been
r_htkl-sign='E'.
then the condition is same but with a NOT.. that means NOT EQ or NOT BT etc.
as exclusive of the option.
etc.
hope this is clear.
AND PLEASE CLOSE THE OTHER THREAD (duplicate) -
String answer = new String("");
in = new BufferedReader(new InputStreamReader( connection.getInputStream ()));
String test = new String("");
for (int i = 0 ; i < 1000 ; i++)
answer = in.readLine();
if (answer == null)
System.out.println ("null");
break;
else
test += answer;
System.out.println ("answer: " + answer);
System.out.println ("test: " + test);
Many times, the loop will go through 2 iterations but each time, test is only equal to the first answer. The second, third, fourth etc.time it goes through the loop, it should concatenate the value of answer to the end of the string variable test. So why is it that whenever i run the program that has this code, the loop might lloop many times (let's say 2 time) but the value of test is only the first answer, and not the first answer concatenated with the second answer.It worked for me...my code looks like this...i used FileInputStream instead of connection..
import java.io.*;
class Forum {
public static void main(String a[]) throws IOException{
String answer = new String("");
BufferedReader in = new BufferedReader(new InputStreamReader( new FileInputStream("hi.txt")));
String test = new String("");
for (int i = 0 ; i < 1000 ; i++)
answer = in.readLine();
if (answer == null)
System.out.println ("null");
break;
else
test += answer;
System.out.println ("answer: " + answer);
System.out.println ("test: " + test);
my hi.txt is like this:
fasd rea reks krie
fsdfasd
asdfasd
sfasdf
asdfasd
The output is
answer: fasd rea reks krie
answer: fsdfasd
answer: asdfasd
answer: sfasdf
answer: asdfasd

hi friends, i came across this code, and i am struck at understanding this code,
usually loop keyword will be followed by itab, but here there is nothing, same with sort.
SORT.

an some one please explain me this code, little briefly.
thank you.sorry friends, i forgot to tell that the following piece of code was above this code:

What files does this code need?
I am trying to use this code from Java Examples In A Nutshell.
It is a short program that involves reading one and writing to another (I think!) The way I understand things is that there has to be two files for the program to be able to run, from_file & to_file . I have attempted to creat two txt files and saved them as these names in the same folder as the app. The code complies as you would expect, when I try to run it I get Usage: FileCopy <source> <destination> and the app never runs. I suspect I have not created the external files properly. If you can see where I have gone wrong let me know, layman's terms please, Dave.When running the compiled "FileCopy.class" with java command you must enter the names of files, i.e.;
java FileCopy "from_file" "to_file"
in the command line.
In this case args[0] is "from_file" and args[1] is "to_file." -
Why does this code always gotoAndStop at the same frame?
The symbol "alldoor" contains the following six frames in sequential order: "door1","red_door1","door2","red_door2","door3" and "red_door3".
var doors:Array =["door1", "door2", "door3"];
var doorSelector:String = doors[newDoors(0, doors.length - 1)]
function newDoors (min:Number, max:Number):Number
var doorColors:Number = Math.round(Math.random() * (min - max) + max);
return doorColors;
alldoor.gotoAndStop(doorSelector);
alldoor.addEventListener(MouseEvent.CLICK,changeColors );
function changeColors(e:MouseEvent)
if (e.currentTarget.currentLabel == doorSelector)
e.currentTarget.gotoAndStop(currentFrame + 1);
I am attempting to get this code select one of the frames starting with the string "door" at start up. Then, the door should move to the frame
directly following it on the timeline when clicked. However, as the code is written, the frame always jumps to the second frame in the symbol,regardless of what the current label is. What should I change?either:
1. those frames aren't loaded when that code executes or
2. you don't have those labels on the timeline that contains that code or
3. there is other code executing after your goto changing your frame
use the trace() function to debug and find which is your problem. -
Repaint() an applet from a swing applet, why does this code not work?
below are three files that work as planned except for the call to repaint(). This is envoked when a button is hit in one applet and it should repaint another applet. I opened them up in a html file that simply runs both applets. If you could see why the repaint doesn't work I'd love to know. good luck.

}I can fix your problems
1. You get an error here because you can only invoke the superclass's constructor in the subclass's constructor. It looks like that's what you're trying to do, but you're not doing it right. Constructors don't return any value (actually they do, but it's implied, so you don't need the void that you've got in your code)
2. I'm not sure, but I think your call to show might be wrong. Move the setsize and setvisible calls to outside of the constructor -
ADF 10g: What does this code do?
What is the difference between this and calling createRootApplicationModule() ? I'm looking for some definitive documentation on this.
FacesContext fc = FacesContext.getCurrentInstance();
ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(fc);
DCDataControl dc = bc.findDataControl(amName);
ApplicationModule am = (ApplicationModule)dc.getDataProvider();I understand it (the above code) is no different from picking it from a specific pageDefinition (say where an action binding to a method of that AM is present) or the above -
both return an AM instance from the data controls within the current FacesContext. But still, any documentation that would relieve this information itch would be much appreciated.
Also, any thoughts on the 'best practiceness' quotient of doing the above?
Edited:
This is posted just to seek clarification - please refer to the whole thread, links provided as references and the developer guide for the recommended approaches.posted will grab the one that has been checked out for the page by the binding filter.Here's the thing: this AM, its methods or any of it's constituent VO attributes do NOT have a binding (but could have, since this AM is exposed in the data controls)
Just note the use of that #{"data"} EL used above (not #{"bindings"} or #{"data.pageDefName"} ).
In most all cases, you want the same one that has already been checked out - so getting it via the binding context is preferred.Precisely - is there official documentation that confirms that this is a preferred way?
It is generally pretty rare where you need to createRootApplicationModule,In fact, not at all - except in test code.
but you might do so in cases where there is not one already checked out for you (for example, if you are interacting with ADF BC from within a servlet).It would be great to have documentation that says it's ok to do so. Otherwise, I strongly think things could be designed better to even avoid doing that.
Furthermore, it would be even more preferred not to interact with the AM directly in code, but to expose any methods you might want to call via the data control.Method bindings would be 'ideal'. Using the client interface is currently 'ok' (or at least a lesser evil).
In any new code I wouldn't interact with an AM in UI code - just that there is a whole lot of legacy code which does so. I'm just making sure that the above alternative to createRootApplicationModule is not just equally bad. (i.e. does not require an explicit 'release' call)
http://blogs.oracle.com/smuenchadf/2009/09/best_practice_example_for_invo.htmlTotally agree with with the above - and yet get hold of an AM instance via its interface the 'right' way in old code that needs it.
Thanks for the response.
