0. "DECLARE" is missing (or CREATE PROCEDURE...)
1a. emp_typ is declared but never used. Not strictly an error but suspicious.
1b. In the code, emp_no is a number but is declared here as a varchar2. Yuck.
2. fine.
3. fine.
4. fine.
5. You can't directly assign a sequence like this. It must be part of a sql statement.
6. Omit the parentheses around emp_rec.

I purchased Adobe Acrobat x Pro recently and installed it, I have compatibility issues vision 2013. The adobe pdf converter plug in stays inactive despite all my efforts to activate it, I need help with this? How can i get the plug in to work with Visio 2013?
For MS Visio (any version) only the appropriate version of Acrobat *PRO* provides PDFMaker for Visio.
For Visio 2013 specifically you must have Acrobat XI Pro (updated to at least 11.0.1).

Hi!!
I urgently need help with this:
When I compile this in Flex Builder 3 it says: The element type 'mx:Application' must be terminated by the matching end-tag '</mx:Application>'.
but I have this end tag in my file, but when I try to switch from source view to desgin view it says, that: >/mx:Script> expected to terminate element at line 71, this is right at the end of the .mxml file. I have actionscript(.as) file for scripting data.
This is the mxml code to terminate apllication tag which I did as you can see:

Please I really need help with this video problem.
Hi!
Please I need help with this app I am trying to make for an Android cellphone and I've been struggling with this for a couple of months.
I have a main flash file (video player.fla) that will load external swf files. This is the main screen.When I click the Sets Anteriores button I want to open another swf file called sets.swf.The app is freezing when I click Sets Anteriores button
Here is the code for this fla file.
import flash.events.MouseEvent;
preloaderBar.visible = false;
var loader:Loader = new Loader();
btHome.enabled = false;
var filme : String = "";
carregaFilme("home.swf");
function carregaFilme(filme : String ) :void
var reqMovie:URLRequest = new URLRequest(filme);
loader.load(reqMovie);
loader.contentLoaderInfo.addEventListener(Event.OPEN,comeco);
loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,progresso);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,completo);
palco.addChild(loader);
function comeco(event:Event):void
preloaderBar.visible = true;
preloaderBar.barra.scaleX = 0;
function progresso(e:ProgressEvent):void
var perc:Number = e.bytesLoaded / e.bytesTotal;
preloaderBar.percent.text = Math.ceil(perc*100).toString();
preloaderBar.barra.scaleX = perc;
function completo(e:Event):void
preloaderBar.percent.text = '';
preloaderBar.visible = false;
btHome.addEventListener(MouseEvent.MOUSE_DOWN,onHomeDown);
btHome.addEventListener(MouseEvent.MOUSE_UP,onHomeUp);
btSets.addEventListener(MouseEvent.MOUSE_DOWN,onSetsDown);
btSets.addEventListener(MouseEvent.MOUSE_UP,onSetsUp);
btVivo.addEventListener(MouseEvent.MOUSE_DOWN,onVivoDown);
btVivo.addEventListener(MouseEvent.MOUSE_UP,onVivoUp);
btHome.addEventListener(MouseEvent.CLICK,onHomeClick);
btSets.addEventListener(MouseEvent.CLICK,onSetsClick);
function onSetsClick(Event : MouseEvent) : void
if (filme != "sets.swf")
filme = "sets.swf";
carregaFilme("sets.swf");
function onHomeClick(Event : MouseEvent) : void
if (filme != "home.swf")
filme = "home.swf";
carregaFilme("home.swf");
function onHomeDown(Event : MouseEvent) : void
btHome.y += 1;
function onHomeUp(Event : MouseEvent) : void
btHome.y -= 1;
function onSetsDown(Event : MouseEvent) : void
btSets.y += 1;
function onSetsUp(Event : MouseEvent) : void
btSets.y -= 1;
function onVivoDown(Event : MouseEvent) : void
btVivo.y += 1;
function onVivoUp(Event : MouseEvent) : void
btVivo.y -= 1;
Now this is the sets.fla file:
Here is the code for sets.fla
import flash.utils.Timer;
import flash.events.TimerEvent;
var video:Video;
var nc:NetConnection;
var ns:NetStream;
var t : Timer = new Timer(1000,0);
var meta:Object = new Object();
this.addEventListener(Event.ADDED_TO_STAGE,init);
function init(e:Event):void{
video= new Video(320, 240);
addChild(video);
video.x = 80;
video.y = 100;
nc= new NetConnection();
nc.connect(null);
ns = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, onStatusEvent);
ns.bufferTime = 1;
ns.client = meta;
video.attachNetStream(ns);
ns.play("http://www.djchambinho.com/videos/segundaquinta.flv");
ns.pause();
t.addEventListener(TimerEvent.TIMER,timeHandler);
t.start();
function onStatusEvent(stat:Object):void
trace(stat.info.code);
meta.onMetaData = function(meta:Object)
trace(meta.duration);
function timeHandler(event : TimerEvent) : void
if (ns.bytesLoaded>0&&ns.bytesLoaded == ns.bytesTotal )
ns.resume();
t.removeEventListener(TimerEvent.TIMER,timeHandler);
t.stop();
The problem is when I test it on my computer it works but when I upload it to my phone it freezes when I click Sets Anteriores button.
Please help me with this problem I dont know what else to do.
thank youMy first guess is you're simply generating an error. You'll always want to load this on your device in quick debugging over USB so you can see any errors you're generating.
Outside that, if you plan on accessing anything inside the SWF you should be loading the SWF into the correct context. Relevant sample code:
var context:LoaderContext = new LoaderContext();
context.securityDomain = SecurityDomain.currentDomain;
context.applicationDomain = ApplicationDomain.currentDomain;
var urlReq:URLRequest = new URLRequest("http://www.[your_domain_here].com/library.swf");
var ldr:Loader = new Loader();
ldr.load(urlReq, context);

If you're doing this on iOS you'll need to stripped SWFs if you plan on using any coding (ABC) inside the files. You mentioned iOS so I won't get into that here, but just incase, here's info on stripping external SWFs:

The only way around this is to delete the apps that require the other Apple ID and download them again with yours.

FormsCentral retiring in July???!!! Are you freaking kidding me? My clients use this feature all the time. What do you suggest I do now? What service do I go with that is comparable to it? I need help with this asap!
I would suggest checking out http://www.logiforms.com. They have really good PDF support for both hosted PDF's and generating PDFs. You can:
populate PDF forms from a web form submission
Merge multiple PDF's together using conditional logic
Include uploaded images in the generated PDF
Get Electronic signatures on PDF's
Use conditional logic when creating PDF's
Convert HTML to PDF. You design in HTML and CSS and use form field wildcards and generate the PDF
More of the PDF features are explained here:
PDF Form Creator | PDF Form Maker | V3.Logiforms.com
They are also offering a 25% discount to anyone coming from Forms Central... -

I just downloaded an album from itunes and 2 of the tracks will not play at all, they cut off. I need help with this??
Does the track play correctly in Quicktime Player? If it does then it is an iTunes issue. If it doesn't then it is possible the file was not completely downloaded, or is corrupt.

Need help with this xml gallery !!!
i have build a gallery but its very simple...... it takes images from xml file.
i have attached all files in zip.
i just want two things if anyone can help.
first when i press next button it goes to next image but with no effect. it just displays next image ... i want to incorporate a sliding effect when the image is changed to another.
and second i want to use autoplay feature.
as soon as swf starts the images came one by one with difference of few seconds.
thx in advance... i really need help in this....!You're welcome.
I don't have an example to offer for the autorun. You should be able to think it thru. One key, as I mentioned is to preload all of the images first, that will allow for smooth playing of the show--no waiting for images to load between changes. You can load them into empty movieclips and hide them (_viisible = false) until they are needed. You could load them when called for, but you would have to put conditions on the displaying of things until the image loads, which will change when they are all loaded, so I recommend just loading them all first.
For the timing you can use setInterval. If something is going to be allowed to interupt the autorun, then you will need to make use of the clearInterval function as well, so that you stop the clock.
Since you will be wanting to know when things are loaded, you will need to use the MovieClipLoader.loadClip method for loading the images instead of using loadMovie. This is because the MovieClipLoader class supports having an event listener. If you look in the help documents in the MovieClipLoader.addListener section, there is an example there that provides a fairly good complete overview of using the code. The only difference is you'd be looking for the onLoadComplete event rather than the onLoadInit event. -
Need help with this Pascal Triangle code....
Hey everyonr i am totally new to Java... so need your help with this code...
the function makeRows gives me problems... main is correct ... can someone fix my makeRows... i don't see what's wrong
public class Pascal {
/** Return ragged array containing the first nRows rows of Pascal's
* triangle.
public static int[][] makeRows(int nRows) {
int[][] mpr = new int[nRows+1][];
int l=0; int r=0;
for (int row = 0; row < nRows; row++) {
mpr[row] = new int[row+1]; //index starts at 0
if (row==0) {
mpr[0][0]= 1;
if (row==1) {
mpr[1][0]= 1;
mpr[1][1]= 1;
if (row>=2) {
for (int j = 0; j <= row; j++) {
if (j==0) {l=0;} else {l=mpr[row-1][j-1];}
if (j==mpr[row].length-1) {r=0;} else{r=mpr[row-1][j];}
mpr[row][j] = l + r;
return mpr;
public static void main(String[] args) {
if (args.length != 1) {
System.out.println("usage: java " + Pascal.class.getName() + " N_ROWS");
System.exit(1);
int nRows = Integer.parseInt(args[0]);
if (nRows > 0) {
int[][] pascal = makeRows(nRows);
for (int[] row : pascal) {
for (int v : row) System.out.print(v + " ");
System.out.println("");
}this makeRows function should return ragged array containing the first nRows rows of Pascal's triangle
thanks
Edited by: magic101 on May 9, 2008 4:03 PMmagic,
i think corlettk meant that some people might not know what pascal's triangle is.
also, you didnt say what was wrong with your code, just that it was wrong.
asking smart questions is about giving as much information you can to get the
best answer. i would throw a System.out.print between every line of your
algorithm. i would also supply us with the values you are getting for each row.
also, this question is asked all the time here. do a forum search.

Need help with this book problem...Pig game...can ANYONE help!??
I need help with the following book problem...could someone write this code for me?? Thanks!!
First design and implement a class called PairOfDice, composed of two six-sided Die objects. Using the PairOfDice class, design and implement a class to play a game called Pig. In this game, the user competes against the computer. On each turn, the current player rolls a pair of dice and accumulates points. The goal is to reach 100 points before your opponent does. If, on any turn, the player rolls a 1, all points accumulated for that round are forfeited and control of the dice moves to the other player. If the player rolls two 1s in one turn, the player loses all points accumulated thus far in the game and loses control of the dice. The player may voluntarily turn over the dice after each roll. Therefore the player must decide to either roll again (be a pig) and risk losing points, or relinquish control of the dice, possibly allowing the other player to win. Implement the computer player such that it always relinquishes the dice after accumulating 20 or more points in any given round.
I realize this is a long code, so it would be greatly appreciated to anyone who writes this one for me, or can at least give me any parts of it. I honestly have no clue how to do this because our professor is a dumbass and just expects us to know how to do this...he doesn't teach us this stuff...don't ask. Anyways, thanks for taking the time to read this and I hope someone helps out!! Thank you in advance to anyone who does!!!Nasty comments? It's not a matter of not liking you, it's a matter of responding to the
"I'ts everyone else's fault but mine" attitude of your post.
If you are genuine, the program is very easy to write, so, your Professor is correct when he said you should
be able to do it. I'm still very much in the beginner category at java, and it took me only 20 mins to write
(+5 mins to design it on paper). 2 classes in one file < 100 lines. Most of the regulars here would do it in half the time / half the lines.
All of the clues are in the description, break them down into their various if / else conditions. Write it down on paper.
Have a go. Try to achieve something. Post what you've tried, no-one will laugh at you, and you will be
pleasanty surprised at the level of help you will get when you've "obviously" made some effort.
Again, have a go. If you don't like problem-solving, then you don't like programming. So, you gotta ask
yourself - "what am I doin' here?"
