Array issue

Greetings,
I have a problem that I cannot figure out how to solve. I have an array of strings. I need to figure out how to tell how many fields of the array have a value. That is, if an array of 100 strings only containts 10 values, then the number returned is 10.
Any help is greatly appreciated.

test each position of the array for null value,
if ! null increment a counter.

Learning java programing - Array issues.

Hi Everyone,
I just started in java programming and into Arrays multidimensional. I started a simple 2 dimensional array with 5 names with genders. I 'm having issues because it does not want to print out the names with correct genders Male/ Female. The simple program should print out the 5 names with gender type.
example:
Jack - Male
Sally - Female
Dave - Male
Sue - Female
Brian - Male
Here is what I came up with so far:
public class Multiname
     public static void main(String[] args)
          //String[][] multiname;
          String [][] multiname =
                    {"Jack", "sally"},
                    {"Dave", "Brian"},
                    {"Sue"}
          /* multiname [0][0] = "Jack";
          multiname [0][1] = "Male";
          multiname [1][0] = "Sally";
          multiname [1][1] = "Female";
          multiname [2][0] = "Dave";
          multiname [2][1] = "Male";
          multiname [3][0] = "Sue";
          multiname [3][1] = "Female";
          multiname [4][0] = "Brain";
          multiname [4][1] = "Male";
          //int rows = 2;
     //int columns = 2;
               for(int i = 0; i < 4; i++)
                    {for(int j = 0; j < 2; j++)
                            System.out.println("multiname " + ": " + multiname [i][j]);
This is the result:
multiname : Jack
multiname : sally
multiname : Dave
multiname : Brian
multiname : Sue
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
     at MultiD.main(MultiD.java:29)
Can someone inform me what is wrong or missing, and what do I need to do to correct this. I'm new to this and I'm a visual person. Any assistance would be appreciated.
Thanks,

Welcome to the forum!
When you post code use \ on the line before and on the line after the code to preserve formatting (read the FAQ). You can use the 'Preview' tab on the reply window to see what your reply will look like.
Please edit your post and add the code tags.

How could it possibly do that when you commented out the lines the put the gender into the arrays?/* multiname [0][0] = "Jack";
multiname [0][1] = "Male";
multiname [1][0] = "Sally";
multiname [1][1] = "Female";
multiname [2][0] = "Dave";
multiname [2][1] = "Male";
multiname [3][0] = "Sue";
multiname [3][1] = "Female";
multiname [4][0] = "Brain";
multiname [4][1] = "Male";
When you are starting out don't use any more data than you need to get things working. You only need two name/gender combinations; any more just gets in the way.

XML and Array issue

I've created an array that loads data from an XML file. Now,
when a button is pressed I want this array to delete all previous
elements found in the array and add new elements coming from the
same XML file. So I created a function called arrayUpdate, here it
is...
function arrayUpdate():Void{
myArray.splice(myArray.length);
When the button is pressed it first calls this arrayUpdate
function and then calls the other function which loads the specific
data from the XML file. But I can't get it to work. It just keeps
adding new data to the old data. Did I do something wrong
here?

function arrayUpdate():Void {
delete myArray;
var myArray:Array = new Array();
}

Internal mic array issue

Hello,
I am using HP Envy dv6-7267cl, I have recently upgraded from windows 8 to windows 8.1, then the hell broke loose on me, Internal microphone does not work, Camera does not work.. Validity finger sensor stopped working
Some how I could get Finger sensor working back, However under device manager
Generic USB Hub (Validity Sensor (WBF) (PID=0018)), If I disable this only then Internal microphone responds.
Webcam has not responded, Youcam software gives a msg to " No webcam detected. try plugging in a webcam into your computer now. if you are using an integrated camera, make sure that it is turned on."
What should I do with this disgusting laptop.. Please help..
Thanks,
Harish

Hi Mpeacemaker, welcome to the HP Forums. I will assume the model number was a typo and reference the "13-2311ee". If I am wrong please let me know. I also will assume this came with Windows 8, as that is the default troubleshooting available on your computers support page. Here is the general troubleshooting to resolve microphone issues: Resolving Microphone and Line-in Problems (Windows 8)
If this does not help, give me more details as to what you have tried.
I look forward to your response.

Timed array issue

Hi all,
I am trying to incorporate a timed array into my website. I want it to pull the timedCount function every 10 seconds. Any help would be greatly appreciated! Here's what i have so far....
Thanks!
Kal
function timedCount()
var whichQuote=get_random();
var c=0
var zen = new Array(3);
zen[0] = "If you do not raise your eyes you will think you are the highest point. . .
Antonio Porchia";
zen[1] = ". . . they're the words you would think I would say if there was a me for you. . .
They Might Be Giants"
zen[2] = "Scar tissue is stronger than regular tissue. Realize the strength, move on. . .
Henry Rollins"
document.write('<div style="z-index: 5; position: absolute; left: 400px; top: 20px;">' +
alert(zen[whichQuote]) + '</div>').value=c;
c=c+1
t=setTimeout("timedCount()",5000)
}

i mean, I would like for one of the quotes to come up at random and change every 10 seconds. Well then you're building three things:
1) a method to grab a random quote from the array
2) a method to display that quote
3) a way to run the above every 10 seconds.
As I recall Javascript has a "setInterval" method that can be used to cause timed events, but I don't know the details. Again, you want a Javascript forum.
Javascript isn't Java. You're more likely to get answers on a Javascript forum somewhere.Sorry about that, I guess i didn't really think about the difference.Actually there's a huge difference...they're syntactically similar in some ways but not in others, and arguably they're not semantically the same at all. They tend to run in vastly different environments too. And they don't share libraries. The main similarity apart from the partial syntax similarity would be that they're both used in web development a lot (although on completely different tiers usually) so developers of each one might travel in the same circles.
Curses to the late Netscape for giving the language such a similar name. Clearly, it wasn't Microsoft who crushed them...it was GOD!

Cast array issue?

Can Java Array Object be cast to another type? For example:
Vector<MyClass> vector = new Vector<MyClass>();
MyClass []mc = (MyClass[])vector.toArray();The last line can't worked.

SteveLam wrote:
MyClass[] mc = new MyClass[vector.size()];
vector.toArray(mc);and it can pass.Strictly speaking your last line should be this:
mc = vector.toArray(mc);While all the implementations I've seen use the array, if its of the correct size, the specification does not require that. A call toArray() can return a new array, as long as it's of the same type as the parameter.

Axis returning array issue

Hi! I'm trying to generate a WSDL from a .java file with the plug-in for Eclipse "Code Generator Wizard - Eclipse Plug-in", available from http://ws.apache.org/axis2/tools/index.html
The method that I'm trying to generate has the following signature :
public String[][] translateConceptsToTerms(String[] conceptURIs, String lang)
So the return type is two dimensional array of Strings. The thing is that the tool generates the following lines in the WSDL :
<xs:element name="translateTermsToConceptsResponse">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" name="return" nillable="true" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
which after that with the tool for generating Java code from WSDL generates as return type ONE dimensional array! (the second tool is from the same plug-in as the first one)
My question is if AXIS2 supports this return type, or there is some problem with the tools ... or something else? If somebody has any idea ...

Hi,
Thanks for the info. A co-worker of mine has got this working. When I try the same thing, I am getting the error.
On comparing the co-worker's and mine XML files, I found that the working example contains following attribute:
ElemType
Whereas my XML file doesn't contain this entry. What do I have to do to get this entry in the XML file - I checked all options in the VO wizard and was unable to find anything.
Please suggest -- thanks in advance!!

Random Sound Array Issue

Been trying to implement a random sound picker on the main
timeline. (Keeping in mind it needs to work in AS1)
All my sounds are correcly identified under the "linkage"

Somehow, my array value always comes up undefined. And none
of the sounds would play.

I can't look at the fla because of my old Flash version but I
looked at your posted code again.
Do you need all that array stuff for anything? I mean, if all
you want to do is play a random song every N seconds you can do it
with just a few lines of code..
function randomSound()
stopAllSounds();
var snd = new Sound();
var g = random(2) + 1; // 1, 2 or 3
snd.attachSound("s"+g); // s1, s2 or s3
snd.start(0, 1);
randomSound(); // start the first song now
id = setInterval(randomSound, 10000); // change songs every
10 seconds
Make sure you have 'linkage' names for your 3 songs (not
library names)
Your original code did play 1 song every 1 second (just makes
a popping sound when changing that fast) so I suspect that your
linkage names were missing.
I wouldn't use a recursive coding like that though. (a
function that calls itself)

Cannot Access Array Issue

I cant seem to get the array to be read from outside of the public MyBuffer part of the class. I need to be able to access theArray from the rest of the class. Does anyone know what I did wrong here? Thanks!
public class MyBuffer<T> extends Object implements Bufferer, SaveRestore
     public MyBuffer(int x)
          Object[] theArray = new Object[x];
     public boolean produceItem(Object item)
          try {
          //puts the items into the array from the assign classes
               //THIS IS THE PROBLEM - I need to be able to assign items to the array and in other portions i need to be able to read them back.
          //theArray[size]=item;
          size++;
          return true;
          //catches an array exception
          } catch (ArrayIndexOutOfBoundsException e){
               return false;
     }

I actually just didnt think of that. Now that works!!!
Now I've gotta get it to write. This method of writing seems to work fine for when I just plug in a number instead of the theArray[i] in there. I dont see why it shouldnt work when all I did was put theArray[i] instead of a number?
This is the error I get:
.\MyBuffer.java:91: cannot find symbol
symbol : method write(java.lang.Object)
location: class java.io.BufferedWriter
                                out.write(theArray);
And this is my code for that section:          try {
               BufferedWriter out = new BufferedWriter(new FileWriter(fileName));
               for (int i=0;i<=size;i++)
                    out.write(theArray[i]);

               out.close();

P6N SLI Platinum (MS-7350) Bootable Raid Array issues

Attempting to install XP on bootable SATA Raid after text portion of install on reboot receive error message.
"A disk read error occured"
Manual has incorrect dir structure x:\nvidia\system\c55+mcp51\raid <-- does not exist
there is a sataraid folder under xp subfolder which appears to contain the storage controller drivers.
Additionally have attempted to download the sataraid drives from the website with the problem
During the Windows text install it does appear to see the drives as I can format them and install the setup files accordingly but it shows both drives which set to striping I would expect to see only one drive as listed in the bios "Sata Raid XXX.XX"
These drives are good I have tested them on another system without an issue.

Quote from: garley on 04-May-07, 09:41:59
Alrighty,
So just to recap,
You have two Disks you are trying to setup as Raid 0? (What size drives?/ model?)
You have them connected to sata connector 1 and 3, No other drives connected?
Cdrom as master on Secondary IDE Controller and Primary disabled in the bios?
SataRaid is set as the 1st boot device in boot sequence and CDrom second, Third device disabled.
And you have the same drivers I used from Nvida.
Right. They are WD Raptor 150 GB ADFD 10,000 RPM drives.
Correct. SATA1,3. No other HDD's installed.
DVD on IDE2 connection on Mainboard...shows up as Secondary IDE Master in BIOS. I had the Primary IDE Master set on "not installed", and it shows up as "not detected" in the BIOS.
I HAD the boot sequence as: DVD, RAID, disabled. I changed the boot sequence to Raid, DVD, disabled, did the "save and exit" and it went to a black screen with the cursor blinking. So I powered off wit the power button, waited 15 sec, then powered back on with the power button...same thing...black screen with blinking cursor. If I set the order back to DVD, SATA, disabled, I get back to the point I was where I started, that is: bios showing everything right, but xp install showing two drives. I don't know why it gives the black screen when the RAID is set to first boot since it is supposed to skip it if it doesn't work and move on to the next in line, which would be the DVD.

AS3 and/or PHP Array Issue

Good day,
Does anyone have any ideas (better yet, an effective
solution) as to why the following PHP code:

That is odd,
Using this php -
<?php
$getYear=$_POST['year'];
$getMonth=$_POST['month'];
$getDate=$_POST['date'];
//omitted host etc...
$con = mysql_connect($host,$username,$password);
if (!$con)
die('Could not connect: ' . mysql_error());
mysql_select_db($db_name, $con);
$result = mysql_query("SELECT * FROM calendar WHERE
year='$getYear' AND month='$getMonth' AND date='$getDate'");
$return = "";
// Loop thru and pull out all records
while($row = mysql_fetch_assoc($result))
$return = $return . "year=" . $row["year"] ."&";
$return = $return . "month=" . $row["month"] ."&";
$return = $return . "date=" . $row["date"] ."&";
$return = $return . "time=" . $row["time"] ."&";
$return = $return . "title=" . $row["title"] ."&";
$return = $return . "description=" . $row["description"]
$return = $return . "type=" . $row["type"] ."&";
// Get rid of the last ampersand and echo the string
$return = substr($return, 0, -1);
echo $return;
mysql_close($con);
?>
and this AS
var url:String = phpURL;
var reqURL:URLRequest = new URLRequest(url);
reqURL.method = URLRequestMethod.POST;
var variables:URLVariables = new URLVariables();
variables.year = "2008";
variables.month = "9";
variables.date = "29";
reqURL.data = variables;
var ldr:URLLoader = new URLLoader(reqURL);
ldr.dataFormat = URLLoaderDataFormat.VARIABLES;
ldr.addEventListener(Event.COMPLETE, handleComplete);
function handleComplete( event:Event ):void
var ldr:URLLoader = URLLoader(event.target);
var vars:URLVariables = new URLVariables(ldr.data);
trace("year="+vars.year);
trace("month="+vars.month);
trace("day="+vars.date);
trace("time="+vars.time);
trace("title="+vars.title);
trace("description="+vars.description);
trace("type="+vars.type);
yields in the flash output panel
year=2008,2008
month=9,9
day=29,29
time=5:00,6:00
title=Test Event,test event 2
description=this is a test event to test the functionality of

type=1,1
No problem with testing in the flash IDE.

Array issues..

I'm trying to multiply 2 matrices.. the user provides the size of the matrices and also types in the elements.
Thats fine, but when i try to do the calculation it ends in arrayIndexOutOf..... exception. Here is my code:

Path tool long when using arrays

Hey Powershell people. I'm running into an array issue in powershell where the error "Copy-Item : The specified path, file name, or both are too long" is thrown back at me. However, the odd thing is if I type the copy path in manually the script it works
fine, so the error only occurs when the script directly references the item in the array by its numbered location. Eventually, I want to create a for loop for this that will reference each file name in the array, so i'm hoping I can directly reference
the array pointer.
$DTS = get-date -format "dd-MM-yyy_hh-mm-ss"
New-Item c:\$DTS -type directory
$get = Get-Content C:\array.txt
Start-Sleep -s 1
$testdata=@"
$get
($testdata | Select-String -Pattern '(?<=t.s.\\.).+?(?=\. u s p)' -AllMatches).Matches | %{$_.Value} | Out-File c:\test.txt
Start-Sleep -s 1
$get2 = Get-Content C:\test.txt
$get2 = $get2 -replace " ", "" | Out-File c:\test.txt
$get = Get-Content C:\test.txt
Copy-Item "\\server\C$\Program Files\Projects\$get[0].usp" \\server2\C$\$DTS
Note, if I do something like $get4 = $get[0] the script will properly reference $get[0] if $get4 is inserted into the copy path .

Sorry, let me try to explain a little better. The script is suppose to create a folder using the date/time on root C:, read from array.txt file (has the file
information in it), parse out all files names from array.txt into text.txt, parse out all spaces from text.txt, use the file names in text.txt array as a variable to copy the files from one location to another.
Pseudo Example
Parsed file names in text.txt
1234567890
0987654321
6789054321
Loop Pseudo
$filename[] = ReadFrom text.txt
Loop through all file names in text.txt
CopyFrom C:\FilePath\$filename[].usp to C:\FolderWithDateAndTime

Deadlock issue in Partitioned Tables

Hi ALL,
I am facing an issue of Deadlock while inserting data into a partitioned table.
I get an error "ORA-00600: Deadlock detected". when i see the trace files, following lines are appearing in them:
"Single resource deadlock: blocking enqueue which blocks itself".
Here is the detail of my test case:
1. I have a list-partitioned table, with partitioning defined on some business codes.
2. I have a query that merges data into partitioned table (actually compares unique keys between temporary table and partitioned table and then issue an insert if keys not matched, no update part).
3. The temporary table contains transactional data against many business codes.
3. when calling the above query from multiple (PL/SQL) sessions, i observe that when we merge data in same partition (from different sessions) than deadlock issue occurs, otherwise it is OK.
4. Note that all sessions are executed at same time. Also note that Commit is called after each session is completed. Each session contains 2-3 more queries after the mentioned merge statement.
Is there an issue with oracle merge/insert on same partition (from different sessions)? What is the locking mechanism for this particular case (partitioned tables)?
My oracle version is Oracle 10g (10.2.0.4). Kindly advice.
Thanks,
QQ.

Oracle MERGE statements are slow as they must validate every record before insert.
If you use array processing with BULK COLLECT and FORALL with the SAVE EXCEPTIONS clause you can avoid most of the overhead. Just collect your rows in an array, issue a FORALL INSERT SAVE EXCEPTIONS and let Oracle handle whatever happens.
When Oracle is done, and it will be hundreds of times faster than what you are doing now, you can either process or ignore the records in the exceptions array.
Another solution, more efficient if you can do it, is to just to an INSERT INTO SELECT FROM using an exceptions table created with DBMS_ERRLOG.

Quicktime 7.2 and Vista with RAID Arrays

Has anybody been brave enough to install Quicktime 7.2 on their Vista computer which also has a RAID 0 or 1 array? Previous versions of Quicktime have crashed the RAID array necessitating a new computer the first time and a rebuild of the backup RAID driver the second time.
I want to have iTunes and Quicktime on my Vista machine because I have an iPhone and it only syncs with iTunes but I am afraid to try it again. I updated my BIOS and the Intel RAID drivers with a Dell technician a few days ago so I have their "current" drivers but still am not sure this will "fix" the Quicktime crashing Vista RAID array issue.
Any brave souls out there that have tried the latest version with Vista and a RAID array?
PS - I run the latest version of iTunes (7.3.1) and Quicktime (7.2) on my Sony VAIO laptop with Windows XP and it works and I can sync the iPhone there for now.
Dell XPS 410 Windows Vista RAID 1 Array

That sounds good. Those are what i was hopeful about in your case. I haven't seen a report yet of the Intel Matrix issues being fixed by the Dell-tweaked versions of the Matrix updates. However, there have been successes reported with the direct-from-Intel versions of those updates. For example:
http://discussions.apple.com/message.jspa?messageID=4677972#4677972
(I'm thinking however, that if the PC manufacturer offers its own versions of the updates on its downloads pages for a model, those are the drivers that folks should go for with their models.)
Prior to those updates to the Intel Matrix coming out, the state of the art treatment (using the older models of the Matrix drivers/application) is discussed in this post:
