Some Help with using C

Hello,
I'm developing apps geared at the kids market and am learning much of this for the first time. I am in the processing of covering some basics of the C language before moving on into Objective C and Cocoa and ran into a problem understanding the lesson I was using...check this out...
' % is a binary operator that returns the remainder when the left operand is divided by the right operand. For example, i % 2 divides 2 into i and returns the remainder. If i is even, this remainder will be 0. If i is odd, this remainder will be 1.
if ( (i % 2) == 0 )
printf( "even" );
else
printf( "odd" );
In the expression i % 3, the remainder will be 0 if i is evenly divisible by 3, and either 1 or 2 otherwise.
if ( (i % 3) == 0 )
printf( " and is a multiple of 3" );
Dividing 1 by 2 does not give an answer of 1 or 0 but rather 0.5. So what is this guy talking about? How are they getting 1 or 0 as an answer?

Looking for some help with using Oracle stored procedures in vb2010

First off thank you to whoever lends me a hand with my problem. A little background first I am in a software development class and we are currently building our program using VB (I have no experience in this), and Oracle(currently in a Oracle class so I know how to use Oracle itself just not with VB).
I am using vb2010 express edition if that helps. Currently I have a stored procedure that takes a 4char "ID" that returns a position (ie, salesperson,manager ect). I want to use the position returned to determine what vb form is displayed (this is acting as a login as you dont want a salesperson accessing the accountants page for payroll ect).
Here is the code I have currently on the login page of my VB form
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Login
Dim conn As New OracleConnection
Private Sub empID_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles empID.Click
End Sub
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
conn.ConnectionString = "User ID = Auto" & _
";Password = ********" & _
";Data Source = XE"
conn.Open()
Dim sq1 As String = "Return_Position" 'name of procedure
Dim cmd As New OracleCommand(sq1, conn)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add(New OracleParameter("I_EmpID", OracleDbType.Char, 4)).Value = Emp_ID.Text
Dim dataReader As OracleDataReader = cmd.ExecuteReader
dataReader.Read()
Dim position As New ListBox
position.Items.Add(dataReader.GetString(0)) 'were I am getting an error, I also tried using the dataReader.getstring(0) to store its value in a string but its a no go
If position.FindStringExact("MANAGER") = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False
End Sub
I have read the oracle.net developer guide for using oracle in vb2010 and have successfully gotten through the document however they never use a stored procedure, since the teacher wants this program to user a layered architecture I cannot directly store sql queries like the document does, thus the reason I want to use stored procedures.
This is getting frustrating getting stuck with this having no background in VB, I could easily do this in c++ using file i/o even through it would be a pain in the rear....

Hello,
I am calling Oracle 11g stored procedures from VB.Net 2010. Here is a code sample (based on your code) you should be able to successfully implement in your application.
Please note that you may have to modify your stored procedure to include an OUT parameter (the employee position) if it doesn't have it yet.
Private Sub LoginBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoginBtn.Click
Dim sProcedureName As String = "Return_Position" 'name of stored procedure
Dim ORConn as OracleConnection, sConn as String
Dim sPosition as String, sDataSource as String, sSchema as String, sPWD as String
Dim cmd As OracleCommand
'please provide below sDataSource, sSchema and sPWD in order to connect to your Oracle DB
sConn = "Data Source=" & sDataSource & ";User Id=" & sSchema & ";Password=" & sPWD & ";"
ORConn = New OracleConnection(sConn)
ORConn.Open()
cmd = New OracleCommand(sProcedureName, ORConn)
With cmd
.CommandType = Data.CommandType.StoredProcedure
'input parameter in your stored procedure is EmpId
.Parameters.Add("EmpID", OracleDbType.Varchar2).Value = Emp_ID.Text
.Parameters.Item("EmpID").Direction = ParameterDirection.Input
'output parameter in your stored procedure is Emp_Position
.Parameters.Add("Emp_Position", OracleDbType.Varchar2).Direction = ParameterDirection.Output
.Parameters.Item("Emp_Position").Size = 50 'max number of characters for employee position
Try
.ExecuteNonQuery()
Catch ex As Exception
MsgBox(ex.Message)
Exit sub
End Try
End With
sPosition = cmd.Parameters.Item("Emp_Position").Value.ToString
'close Oracle command
If Not Cmd Is Nothing Then Cmd.Dispose()
Cmd = Nothing
'close Oracle connection
If Not ORConn Is Nothing Then
If not ORConn.State = 0 Then
ORConn.Close()
End If
ORConn.Dispose()
End If
ORConn = Nothing
If UCase(sPosition) = "MANAGER" Then
Me.Hide()
Dim CallMenu As New Menu()
CallMenu.ShowDialog()
End If
LoginBtn.Enabled = False
End Sub
If you need further assistance with the code, please let me know.

M. R.

Morning AndreD86,
Thanks for using Apple Support Communities.
These articles explain exactly what is backed up by using their method.
iTunes: About iOS backups
http://support.apple.com/kb/ht4946
and
iCloud: Backup and restore overview
http://support.apple.com/kb/ht4859
Also we want to double-click the Home button and swipe the Task Bar to the right.
Then make sure the button on the far left of Task Bar is not muted.
Best of luck,
Mario

Hoping for some help with a very frustrating issue!
I have been syncing calendar and contacts on my iPhone 5 and Outlook 2007 using iCloud 2.1.3 (my PC is running Vista). All was well until the events I entered on the phone were showing up in Outlook, but not the other way around. I’ve tried the usual recommended steps: deselecting calendar and contacts in the iCloud control panel and then re-selecting, signing out of the panel and back in, and repairing the Outlook installation in control panel. I even uninstalled iCloud on the PC and downloaded it again (same version).
The furthest I’ve gotten is step 2 (and once, step 3) of 7 while performing “Outlook Setup For iCloud.” At that point I get, “Your setup couldn’t be started because of an unexpected error.” After the first attempt at all this, all my calendar events disappeared from Outlook, although they are still in iCloud calendar and on my phone.
Sound familiar? Any ideas on how to solve this iCloud/Outlook issue? Thanks much in advance!

Hello everyone, hoping for some help with my new Apple Cinema Display 20"

Hi everyone, I bought an Apple Cinema Display 20 inch LCD monitor, just about 3 weeks ago. I have two issues I am hoping to get some help with.
1) I am using the screen on a PC with Windows XP, and I was very disappointed at the lack of PC support. I have no on screen display (OSD), so I can't see what percentage I have my brightness set to, and I can't alter the colour or contrast of the display, etc. Luckily it defaulted to very good settings, but I would really like to be able to use the (fan made?) program called "WinACD". If I would be best asking somewhere else, please direct me there. If not, my problem is that I installed it added the "Controls" tab, but it just says, Virtual Control Panel "None Present". I have tried googling for an answer, and I have seen many suggestions, but none of them worked. I installed the WinACD driver without my USB lead plugged in, and someone said that was important. So I have tried uninstalling, rebooting, then reinstalling it again with the USB plugged in, and a device plugged in to my monitor to be sure. It didn't seem to help. I have actually done this process a few times, just to be sure. So I would really like to get that working if possible.
2) I am disappointed at the uniformity of the colour on the display. I have seen other people mention this (again, after a google search), and that someone seemed to think it is just an issue we have to deal with, with this generation of LCD monitors. Before I bought this screen, I had an NEC (20wgx2), and it had a very similar issue. Most of the time, you cannot see any problem at all, but if you display an entire screen with a dark (none prime) colour, like a dark blue green colour, you can see areas where it is slightly darker than others. It was more defined on the NEC screen, and that is why I returned it. I now bought this Apple Cinema Display, because it was the only good alternative to the NEC. (It has an 8bit S-IPS / AS-IPS panel, which was important to me). But the problem exists in this screen too. It isn't as bad thankfully, but it still exists... I have actually tried a third monitor just to be sure, and the problem existed very slightly in that one, so I think I am probably quite sensitive in that I can detect it.
It is most noticable to me, because I do everything on this PC. I work, I watch films, and I play games. 99% of the time, I cannot see this problem. But in some games (especially one)... the problem is quite noticeable. When you pan the view around, my eyes are drawn to the slight areas on my screen which are darker, and it ruins my enjoyment. To confirm it wasn't just the game, like I said, I can use a program to make the entire screen display one solid colour, and if you pick the right type of colour (anything that isn't a bright primary colour), I can see the problem - albeit fairly faintly.
I am pretty positive that it is not my graphics card or any other component of my PC, by the way, because everything is brand new and working perfectly, and the graphics card specifically, I have upgraded and yet the problem remains - even on the new card. Also, the areas that are darker, are different on this screen than on the other screens I have used.
So basically, I would like to register my disappointment at the lack of perfect uniformity on a screen which cost me £400 (over double what most 20 inch LCD screens cost), and I would like to know if anybody could possibly suggest a way to fix it?
It is upsetting, becuase although this problem exists on other screens too, this is, as far as I know, the most expensive 20" LCD monitor available today, and uses the best technology available too.
p.s. If anyone would like to use the program that lets you set your entire PC screen a specific colour, it is called "Dead Pixel Buddy", and it is a free piece of software, made by somebody to check for dead pixels. But I found it useful for other things too, including looking at how uniform the colour of the screen is. That's not to say I was specifically looking for this problem by the way... the problem cought my eye.
Thanks in advance!

I've been talking about this on another forum too, and I made some pictures in photoshop to describe the problem. Here is what I posted on the other forum:
Yes, "brightness uniformity" definitely seems to be the best description of my issue.
Basically it just seems like there are very faint lines down the screen, that are slightly darker than the other areas on the screen. They aren't defined lines, and they aren't in a pattern. It's just slight areas that are darker, and the areas seem like narrow bands/lines. Usually you can't see it, but in some cases, it is quite noticeable. It is mainly when I'm playing a game. The slightly darker areas are not visible, and then when the image moves (because I am turning in a car, or turning a plane, or turning in a shooter etc.) the image moves, but these slightly darker areas stay still, and that makes them really stand out.
As for how it looks, I tried to make an example in photoshop:
Original Image:
http://img340.imageshack.us/img340/3045/td1ja9.jpg
Then imagine turning the car around a bend, and then it looks like this:
http://img266.imageshack.us/img266/959/td2hq7.jpg
It's those lines in the clouds. If you can tab between the two images, you can see the difference easily. Imagine seeing those lines appear, every single time you move in a game. (I haven't tested this in movies yet, but I am assuming it's the same).
It isn't very clear on a static image. But when the image moves, the darker areas stay in the same place and it draws your eyes towards them. It isn't terrible, but it is annoying, especially consider how much this screen cost.

Please I need some help with a table

Hi All
I need some help with a table.
My table needs to hold prices that the user can update.
Also has a total of the column.
my question is if the user adds in a new price how can i pick up the value they have just entered and then add it to the total which will be the last row in the table?
I have a loop that gets all the values of the column, so I can get the total but it is when the user adds in a new value that I need some help with.
I have tried using but as I need to set the toal with something like total
    totalTable.setValueAt(total, totalTable.getRowCount()-1,1); I end up with an infinite loop.
Can any one please advise on some way I can get this to work ?
Thanks for reading

Need some help with a Macally enclosure and a spare internal drive

Need some help with a Macally enclousure

Aloha:
I have a Macally PHR-S100SUA enclousure that does not recognise,my WD 1001fals hard drive. It has worked just fine with other internal drives, but not this one?
This is a spare internal drive that I am trying to make an external drive to store back ups for a lot of data. But so far I can not get it recognized by the computer. Maybe I need different drivers?
Any suggestions?
Dan Page

Hi-
Drivers aren't typically needed for external enclosures.
Macally has none listed for that enclosure.
The same is true for the WD drive, internal or external; no drivers.
With the exception of high end PM multi drive enclosures, I can't think of any that use drivers.
How is the external connected?
Have you tried different cables, different ports?
Bad/damaged cables are fairly common.
Have you verified connections inside of the enclosure?

Need some help with putting a folder in users directoryI recomend using System.getProperty( "user.home" ) not a hard-coded value.
This will use the users home folder ( C:\My Documents ) on Win9X (I guess), C:\Documents and Settings\<current user> on Win2K +, and ~ on Unix-a-likes.

Need some help with the Select query.

Need some help with the Select query.
I had created a Z table with the following fields :
ZADS :
MANDT
VKORG
ABGRU.
I had written a select query as below :
select single vkorg abgru from ZADS into it_rej.
IT_REJ is a Work area:
DATA : BEGIN OF IT_REJ,
        VKORG TYPE VBAK-VKORG,
        ABGRU TYPE VBAP-ABGRU,
       END OF IT_REJ.
This is causing performance issue. They are asking me to include the where condition for this select query.
What should be my select query here?
Please suggest....
Any suggestion will be apprecaiated!

Hello Everybody!
Thank you for all your response!
I had changes this work area into Internal table and changed the select query. PLease let me know if this causes any performance issues?
I had created a Z table with the following fields :
ZADS :
MANDT
VKORG
ABGRU.
I had written a select query as below :
I had removed the select single and insted of using the Structure it_rej, I had changed it into Internal table
select vkorg abgru from ZADS into it_rej.

Need some help with threads...

Hello all,
I am working on a project at work, and I am not the best programmer in the world. I have been trying to get my head around this for a couple of days and just cannot get it to work.
I am writing an instrumentation control program that will have three threads. One is the GUI, one will receive control information and set up the hardware, and one will check the hardware status and report it to the GUI periodically. I plan on using the invokeLater() method to communicate the status to the GUI and change the status display in the GUI. Communication from the GUI to the controller thread and from the status thread to the controller thread I had planned on being piped input/output stream as appropriate. I have a control class and a status class that need to be communicated over these piped streams. In some trial code I have been unable to wrap the piped input/output streams with object input/output streams. I really need some help with this. Here is the main thread code:
package playingwiththreads1;
import java.io.*;*
*public class PlayingWithThreads1 {*
public static void main(String[] args) {*
* PipedOutputStream outputPipe = new PipedOutputStream();*
* ObjectOutputStream oos = null;*
* ReceiverThread rt = new ReceiverThread(outputPipe);*
// Start the thread -- First try*
* Thread t = new Thread(rt);*
t.start();*
// Wrap the output pipe with an ObjectOutputStream*
try*
oos = new ObjectOutputStream(outputPipe);*
catch (IOException e)*
System.out.println(e);*
// Start the thread -- Second try*
//Thread t = new Thread(rt);*
//t.start();*
/** Send an object over the pipe. In reality this object will be a
class that contains control or status information */
try
if (!oos.equals(null))
oos.writeObject(new String ("Test"));
catch (IOException e)
try
Thread.sleep(5000);
catch (InterruptedException e)
I read somewhere that it matters where you start the thread relative to where you wrap piped streams with the object streams. So, I tried the two places I felt were obvious to start the thread. These are noted in the comments. Here is the code for the thread.
package playingwiththreads1;
import java.io.*;
public class ReceiverThread implements Runnable {
private PipedInputStream inputPipe = new PipedInputStream();
private ObjectInputStream inputObject;
ReceiverThread (PipedOutputStream outputPipe)
System.out.println("Thread initialization - start");
try
inputPipe.connect(outputPipe);
inputObject = new ObjectInputStream(inputPipe);
catch (IOException e)
System.out.println(e);
System.out.println("Thread initialization - complete");
public void run()
System.out.println("Thread started");
try
if (inputObject.available() > 0)
System.out.println(inputObject.read());
catch (IOException e)
System.out.println(e);
Through testing I have determined that no matter where I start the thread, the thread never gets past the "inputObject = new ObjectInputStream(inputPipe);" assignment.
Could someone please help me with this? There are other ways for me to write this program, but this is the one that I would like to make work.
Many thanks in advance,
Rob Hix

Thanks for the help, but that did not work. I tried flushing the ObjectOutputStream and it is still hanging when initializing the thread.
Here is a better look at the code since I was helped to figure out how to insert it:
The main method:
package playingwiththreads1;
import java.io.*;
public class PlayingWithThreads1 {
    public static void main(String[] args) {
        PipedOutputStream outputPipe = new PipedOutputStream();
        ObjectOutputStream oos = null;
        ReceiverThread rt = new ReceiverThread(outputPipe);
        // Start the thread -- First try
        //Thread t = new Thread(rt);
        //t.start();
        // Wrap the output pipe with an ObjectOutputStream
        try
            oos = new ObjectOutputStream(outputPipe);
            oos.flush();
        catch (IOException e)
            System.out.println(e);
        // Start the thread -- Second try
        Thread t = new Thread(rt);
        t.start();
        /* Send an object over the pipe. In reality this object will be a
         * class that contains control or status information */
        try
            if (!oos.equals(null))
                oos.writeObject(new String ("Test"));
                oos.flush();
        catch (IOException e)
            System.out.pringln(e);
        try
            Thread.sleep(5000);
        catch (InterruptedException e)
}The thread code:
package playingwiththreads1;
import java.io.*;
public class ReceiverThread implements Runnable {
    private PipedInputStream inputPipe = new PipedInputStream();
    private ObjectInputStream inputObject;
    ReceiverThread (PipedOutputStream outputPipe)
        System.out.println("Thread initialization - start");
        try
            inputPipe.connect(outputPipe);
            inputObject = new ObjectInputStream(inputPipe);
        catch (IOException e)
            System.out.println(e);
        System.out.println("Thread initialization - complete");
    public void run()
        System.out.println("Thread started");
        try
            if (inputObject.available() > 0)
                System.out.println(inputObject.read());
        catch (IOException e)
            System.out.println(e);
}Does anyone else have and ideas?

Need some help with ".png" image.

Good day everyone. Here's the run down. I need to add an
image (image "A") ontop of another image (image"B"). Image "B" is a
paterned background. And Image "A" a logo with a transparent
background.
As it stands I have image "A" as a "png" and as you know....
they are fri**ing huge! Haveing it as a "gif" only presents me with
the IE6 problem of it adding a colored background to the image.
So I'm stuck! Can any one tell me or point me in the
difection of a tutorial to tell me the best way to add an image
with a transparent background in Dreamweaver.
Really need some help with this!
Thanks all!

Before going much further I'd recommend reconsidering the use
of a textured background. They are usually included for the benefit
of the site owner only, and likely to annoy visitors. Studies on
the subject suggest they often lead to usability problems. I do
like to header graphic, but at 200K it's kinda heavy and can
probably be optimized.

Need some help with guitar setup...

jeez, never thought i'd be asking a question like this after playing for like 20 years, but i need some help with a guitar setup for mac. i'm gonna list out a lot of crap here that prolly doesn't affect anything at all, but here goes.
Imac 17inch G4 - latest updated OS X... 10.4, or 5, or whatever. garageband 3.0
digitech gnx-3
alesis sr-16
sure mic's
yamaha e203 keyboard
here's the setup:
yamaha is on its own on a usb uno midi interface, sure's connected to gnx's xlr port, alesis connected to gnx's jam-a-long input, '87 kramer vanguard connected to gnx's guitar input. currently running headphones out on gnx to line in on mac.
here's the problem:
everything works beautifully, but my guitar sounds like crap. if i plug headphones into the gnx, it sounds beautiful. that makes me think its some kind of level issue between the gnx's output, and the mac's input, but nothing seems to fix it.
by sounding like crap, i mean way too much bass. sound is muddy, blurry, not crisp... aka crap. i've tried altering both output and input on mac and gnx, and i cant get a combination that works. the gnx has a s/pdif out, can the mac accept that as input? might that help? short of running the gnx to my marshal half stack and mic'ing that, anyone have any suggestions, or use a similar setup?
any help would be greatly appreciated!

anyone? ... any suggestions? I think it might be an issue with the gnx pre-amping the signal as it goes out, and then the mac amping it on the way in, giving me a buttload more signal than i need, but since i cant find a happy level, i'm not really sure. i really dont want to resort to mic'ing my marshall... even with the volume almost off, my jcm900 is WAY too loud for apartment use. its not like i really NEED the guitar to sound perfect, i only use garageband to sketch out ideas for songs between myself and bandmates, but its really annoying to not have my customary crisp distortion. my bass player keeps telling me to use the built in amps, but, not to dis a practically free program, but the built in amps blow, at least after 10 years of marshall tube amplification they do. if anyone has any suggestions that might be helpfull on how i might resolve this, i would be your best friend for life and go to all your birthday parties

Need some help with MDX formula

Hello, I am not finding any good documentation on MDX formulas, there is a specific one that I need some help with....could someone please elaborate what exactly does this formula mean? thanks.
(MEASURES.[SIGNEDDATA],
CLOSINGPERIOD([%TIMEDIM%].
[%TIMEBASELEVEL%]))

If new MEASURE gets added to Measure's table , in BPC Client , etools->client Options-> Refresh Dimensions should get the new measure into the CurrentView .IF not try etools->client Options-> Clear Local application information .
Formula 2 :
(MEASURES.SIGNEDDATA,
CLOSINGPERIOD(%TIMEDIM%.
%TIMEBASELEVEL%))
This formula is used to retrieve AST & LEQ account values.
If current time member is at monthlevel ,ie ClosingPeriod of 2011.FEB is the current member it self ,and would retrieve 2011.FEB value.
If Current time member is at quarter level then ClosingPeriod of 2011.Q1 is 2011.Mar ,and would retrieve 2011.MAR value.
If Current time member is at year level then ClosingPeriod of 2011.TOTAL is 2011.DEC ,and would retrieve 2011.DEC value.
Formula 1 :
MEASURES.SIGNEDDATA
Irrespective of the level of the Time , MEASURES.SIGNEDDATA would retrieve current Time member value.This formula is used to retrieve INC & EXP account values
if current time member is at month level,2011.FEB , 2011.FEB value is retrieved.
if current time member is at quarter level,2011.Q1 , 2011.Q1(JANFEBMAR) value is retrieved.
if current time member is at year level,2011.TOTAL , 2011.TOTAL(JAN,FEB,....,DEC) value is retrieved.
Hope this helps.

Need some help with computation

Hi, I need some help with the following:
My page 3 is a form thats shows, among other things, a document ID (:P3_DOC_ID). Next to this item I have created a button that calls a document selection form (page 10).
On selection this forms sets 2 items:
P10_SELECTED (Y or N)
P10_DOC_ID (the selected documents ID value)
When the user selects a document he returns to the calling form.
On page 3 I now try to capture the selected values. For a test item I managed to do this by defining this items source as:
[PL/SQL function body]
begin
if V('P10_SELECTED') = 'Y'
then
return V('P10_DOC_ID'); -- selected value
else
return V('P3_TEST'); -- else the original value
end if;
end;
However I want P3_DOC_ID to capture the selected value. I tried using a computation but that did not work. Any ideas?
thanks Rene

You might want to check if the "Source Used" attribute for P3_DOC_ID is set to always or to "only when ..." it sounds like you need it set to "only when ..."
If that does not work try this
Place the following in a pl/sql anonymous block and turn off your
computation.
if :P10_SELECTED = 'Y'
then
:P3_DOC_ID := :P10_DOC_ID; -- selected value
else
:P3_DOC_ID := :P3_TEST; -- else the original value
end if;

Need some help with strange sounds in Logic Pro 8

Hi!
I need some help with a problem I have in Logic Pro 8.
When I have arrange window open, suddley strange high tones starts to make noise in my headphones. I don't know where these sounds comes from or why, but I need some help to get them away. Should I just try to contact Apple?
Martin

Hi Martin
Welcome to the forum. Give everyone here some more info about your set up otherwise it may be difficult to figure out what is wrong.
Which mac?
Which OS?
any hardware devices?
if you are listening through headphones using the built in audio from the mac, you may be hearing fan noise or a hard drive spin noise.
