Help with displaying last entry of table
I'm trying to create a simple DB for accounting purposes
where users will fill out a form and when they submit it, they will
get a confirmation number.
This confirmation number will be bases on the last
confirmation number in the database.
So if the last confirmation number was 2939, then the new one
will be 2940.
If someone else adds a new record, then the confirmation
number will be 2941 and so forth.
How can I get this number from the DB and add 1 to it in
order to insert it again in the next row?
I would make it an auto number but it is not saved as auto
number in the DB right now.
Any idea what is the best way to do this?
Thanks
Put the following, in turn, in your search engine
auto increment MS SQL
auto increment MySQL
auto increment Oracle
auto increment Access
auto increment PostgreSQL

Help with display glith using JList
Hi, first post so bit of background - I'm teaching Java at the moment, am fine with command line but am dabbling more with Swing, despite certain glitches I always get ( e.g. the 7-segment display last year) but anyway....
I've been trying to develop a little app that picks random boxers for a computer game. My current problem is that i am trying to add custom boxers and then update the JList and repaint the frame. When I add a boxer i can see it adding to the list, however it is unreadable and displayed too small.
Forgive any bad coding etiquettes - its very much a work in progress from a relatively poor programmer ;)
theBoxers is a JPanel containing the JLists, aWindow is the JFrame, customButton is a button to add a custom fighter - this gets a name from a field, and a weight from a combo box, adds it to an array and then attempts to add it to an array, then re-generate the lists
customButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
addCustom(customCombo.getSelectedIndex(),addCustomName.getText());
System.out.println(customCombo.getSelectedIndex() + addCustomName.getText());
theBoxers.repaint();
aWindow.repaint();
public void addCustom(int theWeight, String theName)
switch(theWeight)
case 0: featherCustoms[featherCustomsSize]=theName;
featherFighters = new JList(featherCustoms);
featherCustomsSize++;
break;
case 1: lightCustoms[lightCustomsSize]=theName;
lightFighters = new JList(lightCustoms);
lightCustomsSize++;
break;
case 2: welterCustoms[welterCustomsSize]=theName;
welterFighters = new JList(welterCustoms);
welterCustomsSize++;
break;
case 3: middleCustoms[middleCustomsSize]=theName;
middleFighters = new JList(middleCustoms);
middleCustomsSize++;
break;
case 4: lightHeavyCustoms[lightHeavyCustomsSize]=theName;
lightHeavyFighters = new JList(lightHeavyCustoms);
lightHeavyCustomsSize++;
break;
case 5: heavyCustoms[featherCustomsSize]=theName;
heavyFighters = new JList(heavyCustoms);
heavyCustomsSize++;
break;
default: System.out.println("Not Added");
break;
}Awww, its nice that DB has someone to comeback and carry on a discussion.....long after its over.
The problem here seems to be your lack of understanding between what a teacher or what an 'instructor' is.
From the way you speak, an instructor appears to be someone who is technically skilled in both coding and teaching Java as a programming language, designed for people who wish to code in Java.
A Teacher is someone who must deliver a wide range of subject knowledge to a wide range of abilities, including those who were unable to pass High-School exams. They are responsible for pitching the subject at the correct level for the student, whilst also teaching towards passing the exam, and ultimately gaining a qualification.
The computing course i am currently teaching does not require OOP, but as Java is the language i was taught at University, and is still often used in our University's, I chose it. I don't pretend to be the best programmer in the world. But I do know that I am teaching the pupils the correct basics, at a higher level than is probably required, to give them the right approach at university. also, this is whilst teaching a large amount of theory.
Whether you agree, or disagree, matters not to me as I think you would be unfamilier with the specification I am currently teaching to, or what area's of study need to be taught. The exam board appears happy, as do past students who are now well into their university course, as did my marker when i achieved my degree.
The code posted in the OP (as stated earlier) had nothing to do with displaying my coding abilities, nor did it display the technique's I use when teaching students. It was a small sample of a program which included a JList which was not displaying properly. I tried to include the whole code but it was too big, therefore it was cut down.
It was a work in progress which i now have working. So now i can look at it again in terms of programming structure. It appears I have made a mistake asking for assistance on here, as instead I got a lecture, with very little insight on your part as to my situation or the nature of the problem/solution.
At the end of the day, each to his/her own opinion. What I will say is that when someone requests help, positive feedback/criticism is well recieved along with instructions/guidance on how the problem can be solved. I feel that I received none of this on here, but this is what I will always provide to the students I teach.
Not everyone is a full-time Java programmer or has the time to hit the highest expectations. -
Help with display quality (LCD TV)
I've hooked up my Mac mini to my Samsung 32" LCD TV via HDMI cable.
The overall quality is just far from desireable and is taking away all of the fun from using this new mac.
I set the resolution output to 720p, which is what the TV supports. So that's good.
I played slightly with the Contrast and Brightness on the TV settings.
But I must be missing something. Although the image is sharp, it's very difficult to read from 6ft away, pictures look terrible (seeing the same picture on a different computer and monitor is so much more revealing), and the display is bad for everything basically.
Please help with any settings suggestions or perhaps a detailed guideline for my setup.
I started to configure a color profile on the display settings but the results weren't that great and I reverted to default. Too many subtle changes. My colorblindness probably doesn't help.
Thanks.Thanks for the response.
It's the latest Mac Mini with 2.5ghz i5, AMD Radeon HD 6630M, and 8GB RAM.
I am familiar with the "Just Scan" setting under picture size on the Samsung TV.
I'll look for the digital noise reduction.
Are there complete guides with recommended settings for different setups? Or maybe even general, that would help me here?
Thanks. -
Help with display settings needed urgently
Graphics and icons that are supposed to be round appear oval. For instance the Safari and App icons on the dock appear very oval. Logos on websites I've visited before and I know are round appear oval.
I've tried all display settings and nothing helps. I'm a designer and this is causing a major hinderance. Everything appears condenced / squashed sideways. I'd be very grateful if someone could help with this.
I've just purchased the laptop. I have been using Mac for a few years and I've always selected the "stretched" option from the Display settings which sorted out the problem completely. A circle looked a proper circle. But in this version the option is not available.
Badly hoping someone can help with this.
Thanks.
Version Details - OS X Lion 10.7.4It sounds like you have selected an incorrect resolution. For starters, are you talking about your Air's display or an external display? You haven't said which Air you have. If you have an 11" model, make sure your display resolution is set to 1366x768. If you have a 13" model, it should be set to 1440x900. These are the proper resolutions for the built in displays. Chosing anything other than the referenced "native" display resolutions will result in distortions or clarity problems.

First of all I have to say the tutorials on this site are extremely helpful. My instructor wants all our java code written as Object Oriented and when I did a search on here for Object Oriented it totally helped out. Now I just need help with the display of numbers, my code works perfectly fine except that the number has wayyyyyyyyyyy to many decimal points after it. I only wanted two.
public class Mortgage
double mtgAmount;
double mtgTerm;
double mtgRate;
double monthPymt;
public void Amount(double newValue)
mtgAmount = newValue;
public double Amount()
return mtgAmount;
public void Term(double newValue)
mtgTerm = newValue;
public double Term()
return mtgTerm;
public void Rate(double newValue)
mtgRate = newValue;
public double Rate()
return mtgRate;
public void calcmonthPymt(double newValue) //(LoanAmt * Rate) / (1- Math.pow(1+Rate,-Term));
monthPymt = (newValue);
public void display()
System.out.println ("The Mortgage Amount is:" +(Amount( ) * Rate( )) / (1- Math.pow(1+Rate( ),-Term( ))));
public static void main (String[] args)
Mortgage Mortgage1=new Mortgage();
Mortgage1.Amount(200000);
Mortgage1.Term(360);
Mortgage1.Rate(.0575);
Mortgage1.display();
}I figured it out, the math is wrong I think but I got everything to display correctly
import java.io.*;
import java.text.*;
import java.text.DecimalFormat;
public class Mortgage
double mtgAmount;
double mtgTerm;
double mtgRate;

public void display()

Help with displaying image received from socket on Canvas
Dear programmers
I know that I'm pestering you lot for a lot of help but I just got one tiny problem which I just can't get over.
I'm developing a remote desktop application which uses an applet as it's client and I need help in displaying the image.
When a connection is made to the server, it continuously takes screenshots, converts them to jpg and then send them to the client applet via socket communication. I've got the the server doing this in a for(;;) loop and I've tested the communication and all seems to be working fine. However the applet is causing some issues such as displaying "loading applet" until I stop the server and then the 1st screenshot is displayed. Is there a way to modify the following code so that it displays the current image onto a canvas while the next image is being downloaded and then replace the original image with the one which has just been downloaded. All this needs to be done with as little flicker as possible.
for(;;)
filename = dis.readUTF();
fileSize = dis.readInt();
fileInBuffer = new byte[fileSize];
dis.readFully(fileInBuffer, 0, fileSize-1);
//Create an image from the byte array
img = Toolkit.getDefaultToolkit().createImage(fileInBuffer);
//Create a MyCanvas object and add the canvas to the applet
canvas = new IRDPCanvas(img, this);
canvas.addMouseListener(this);
canvas.addKeyListener(this);
add(canvas);
}Anyone?

Hi all
I need help with this one ,
Scenario:
When adding a new vendor on the system the vendor is suppose to have a tax clearance certificate and it has an expiry date, so after the certificate has expired a new one is submitted by the vendor.
So i need to know how to have SBO fullfil this requirement ?
Hope it's clear .
Thanks
BonganiHi
I don't have a problem with the query that I know I've got to write , the problem is saving the tax clearance certificate and along side it , its the expiry date.

Help with this cool function: =SUMIF(Table 1::$Month, COLUMN()−1, $Cost)
Hello,
I am a novice with respect to spreadsheet functions and needed a a cashflow spreadsheet. I found this one (Download Cashflow Tracker for Numbers (iWork 09).) which is perfect but the author, I suspect, has not updated his website in years. I attempted contacting him and received no reply.
I receive an error with the following function:
=SUMIF(Table 1::$Month, COLUMN()−1, $Cost)
This occurs when I enter a date in the expense or income table. Entering the date is required to make the spreadsheet work but when I do I receive an error that a number is expected when a date is entered.
Can anyone give me some advice? I would really like to use this spreadsheet.
Thanks!
SteveWhat I have found the simplest approach has been:
1. Cut the Summary by Category table and paste it into the Transaction sheet, giving something like this (after rearranging renaming, etc, as desired):
2. Make sure the links between the two table are still working, make their appearance the way you like, then duplicate that sheet for the other months. Each sheet will then have its separate set of two interconnected tables.
3. Copy paste one of the Summary tables back to the Summary sheet, rename it as desired, and set it up with formulas referencing the tables in the monthly sheets you have set up, something like this:
If you want your summary by month you would set up 12 columns in the main 'Summary by Category' table, with each column referencing a different sheet. Your Budget could be a row above each Actual figure, if you like, with difference in a row below that.
This approach keeps the formulas simple and avoids having to set up fancy SUMIFS extracting data for each month from one big Transaction table.

Help with displaying uploaded document in the table
I have a table that displays documents that are stored in FileNet. Below the table, I have an 'Upload' button that allows users to upload document(s). When I click on the upload button after filling in all the metadata, the file gets uploaded to FileNet, but I do not see the uploaded document displayed in the table. I've tried using the 'Create' operation from the Data Controls, but it only inserts a blank row into the table. What is the best approach to doing this? Thanks.
Hi there:
Please remove the 'Create' button. You should properly use PPR - Partial Page Rendering.
You should make sure the upload file component, the upload button and the table are within the same af:form. Then go to the af:table on your jspx page where you want to display the uploaded file, add the component id of the upload button to the "partialTriggers" of your "af:table", then you should be good to go.
You can find how to properly set PPR from Internet or any Oracle ADF document.
Please mark my answer as 'Correct' or 'Helpful' if it is to you.
Good luck,

Help with displaying BLOBs in OBIEE 11g
I am trying to get OBIEE 11g to display photographs in an Analysis report. I know BLOB fields are not supported, and I have been reading posts on this board and following examples on internet sites that try to get round this problem. But, try as I might, I cannot get those pesky photos to display.
Below are all the steps I have followed. Sorry that there is a lot to read, but I was hoping that somebody has been successful in doing this, and may spot something in one of my steps that I am doing wrong.
ORACLE TRANSACTIONAL SOURCE_
Table : EMPL_PHOTO
Fields:
USN VARCHAR2(11) ( Unique Key )
EMPLOYEE_PHOTO BLOB ( I think the photos are stored as 'png' )
ORACLE WAREHOUSE SOURCE_
Table : D_PERSON_PHOTO_LKUP
Fields :
PERSON_KEY NUMBER(38,0) ( Primary Key - Surrogate )
USN VARCHAR2(11)
PHOTO CLOB
BLOB to CLOB conversion.
I used this function :
create or replace function blob_to_clob_base64(p_data in blob)
return clob
is
l_bufsize integer := 16386;
l_buffer raw(16386);
l_offset integer default 1;
l_result clob;
begin
dbms_lob.createtemporary(l_result, false, dbms_lob.call);
loop
begin
dbms_lob.read(p_data, l_bufsize, l_offset, l_buffer);
exception
when no_data_found then
exit;
end;
l_offset := l_offset + l_bufsize;
dbms_lob.append(l_result, to_clob(utl_raw.cast_to_varchar2(utl_encode.base64_encode(l_buffer))));
end loop;
return l_result;
end;
select usn, employee_photo ,
BLOB_TO_CLOB_BASE64(employee_photo)
from empl_photo
IN OBIEE ADMINISTRATION TOOL_
*1) Physical Layer*
Added D_PERSON_PHOTO_LKUP from Connection Pool
Left it as 'Cachable'
Didn't join it to any tables
Changed field PHOTO to a 'LONGVARCHAR' length 100000
Set USN as the Key ( not the surrogate key )
*2) BMM Layer*
Dragged D_PERSON_PHOTO_LKUP across.
Renamed it to 'LkUp - Photo'
Ticked the 'lookup table' box
Removed the surrogate key
Kept USN as the Primary key
The icon shows it similar to a Fact table, with a yellow key and green arrow.
On Dimension table D_PERSON_DETAILS (Dim - P01 - Person Details) added a new logical column
Called it 'Photo'
Changed the column source to be derived from an expression.
Set the expression to be :
Lookup(DENSE
"People"."LkUp - Photo"."PHOTO",
"People"."Dim - P01 - Person Details"."USN" )
Icon now shows an 'fx' against it.
Note: This table also had it Surrogate key removed, and USN setting as primary key.
*3) Presentation Layer*
Dragged the new Photo field across.
Saved Repository file, uploaded, and restarted server.
ONLINE OBIEE_
Created a new Analysis.
Selected USN from 'Person Details'
Selected Photo from 'Person Details'
Selected a measure from the Fact table
Under column properties of Photo ( data format ) :
- Ticked 'Override Default Data Format' box
- Set to Image URL
- Custom text format changed to : @[html]"<img alt="" src=""@H"">"
Under column properties of Photo ( edit formula ) :
- Changed to : 'data:image/png;base64,'||"Person Details"."Photo"
The Advanced tab shows the sql as :
SELECT
0 s_0,
"People"."Person Details"."USN" s_1,
'data:image/png;base64,'||"People"."Person Details"."Photo" s_2,
"People"."MEASURE"."Count" s_3
FROM "People"
ORDER BY 1, 2 ASC NULLS LAST, 3 ASC NULLS LAST
FETCH FIRST 65001 ROWS ONLY
Going into the 'results' tab, get error message:
+State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43113] Message returned from OBIS. [nQSError: 17001] Oracle Error code: 932, message: ORA-00932: inconsistent datatypes: expected - got CLOB at OCI call OCIStmtExecute. [nQSError: 17010] SQL statement preparation failed. (HY000)+
It doesn't seem to be using the Lookup table, but can't work out at which step I have gone wrong.
Any help would be appreciated.
ThanksThanks, yes I followed http://docs.oracle.com/cd/E28280_01/bi.1111/e10540/busmodlayer.htm#BGBDBDHI, but when I get to the part of setting the LOOKUP function on th Physical source, only ONE physical source is displayed. I need TWO sources ( The Employee Table, and the Photo LookUp.
I have raised this as an error with Oracle. We are now on OBIEE 11.1.1.7, but Oracle say BLOBS are still not supported in that release. It will be fixed in 11.1.1.8 and it will be backported into 11.1.1.6.11
In the meantime we have abandoned showing Photo's in any of our reports. -

you need to have a class Tractor with all those properties and then use readObject.Somehow you need to tell the Encoder/Decoder what Tractor means..
hope this helps!! -
[SOLVED] Need help with rEFInd boot entry for rsync backup
I made a successful backup my arch install to an other internal SSD disk (from my HDD).
But now I can't figure out how to make a boot entry for this drive. The wiki only mentions GRUB, which I do not use.
This is the fstab for my HDD:
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sda5
UUID=c1822e3c-e037-4445-bdd8-b71778237dee / ext4 rw,relatime,data=ordered 0 1
# /dev/sda2 LABEL=SYSTEM_DRV
UUID=D2DF-9F74 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
And this is the fstab on my SSD which I edited:
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sdb1
UUID=c61a1301-4728-465d-b40b-bde5e084eb50 / ext4 rw,relatime,data=ordered 0 1
# /dev/sda2 LABEL=SYSTEM_DRV
UUID=D2DF-9F74 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
But I'm not sure about the /boot entry, do I need something else here?
Afterward I tried updating rEFInd by reinstalling using refind-install, but that did not work.
ps. I dual boot with Windows.
Last edited by Devenda (2014-08-18 07:58:07)I also tried adding the menu entry manually by editing refind.conf but that didn't work. I got:
Invalid loader file!
Error: Not Found while loading vmlinuz-linux
Here is some additional info:
refind.conf:
menuentry "SSD Arch Linux" {
icon /EFI/refind/icons/os_arch.png
volume "ArchSSD"
loader /boot/vmlinuz-linux
initrd /boot/initramfs-linux.img
options "root=/dev/sdb1 ro"
I hope this helps.

Help with drop create and update table
Sir/Madam,
I have joined 5 tables and selected some columns ,then I need to update some columns in that. After updating I need to create a report with the new column values.
To do this my method is to create temp table with the select statement then update the temp table , use this temp table for the report and then drop the temp table.
Is there anyother way to do this ??
Can I create a cursor and update the cursor column ??
Does dynamic sql always be created as procedure ??Hi,
you need to understand how eventing works in BSP and MVC architecture. Pls refer to the below link for a basic understanding of how BSP works - View, Controller and Model class concepts.
http://www.sapdev.co.uk/webapps/bsp/washome.htm
For your requirement -
1. you need a view on which you will create a drop down list UI element and a table view element
2. you will need to create a contoller class - this will be used to handle the event that will be triggered when user selects an entry from drop down list
3. you will need a model class in which you will write the business logic to retrieve employees of selected department.
Pls search this forum or blogs for - data binding with BSPs, Table View. Pls read these concepts and try to develop your requirement. You can come back to this forum if you face any issues during development.
hope this helps. -
Help with displaying errors in jsp using html:errors/
Here is my problem.
In my overridden ActionForm.validate() method, i am returning ActionErrors (as required). When there are input errors in my form submission, the control goes back to the JSP page i used to read user input (so far so good). The JSP page is rendered fine for taking input for the second time but no errors are displayed although i am using the tag <html:errors/>
I tried to find the org.apache.struts.action.ERROR in my request attributes and it is there with the size of 1 (because i am reporting one error, in my sample run). Any idea why <html:errors/> won't display the errors even though they are there??? Here is what i am doing in my ActionForm class:
public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (this.email == null || this.email.length() < 1) {
errors.add("username", new ActionError
("error.username.required"));
return errors;
Any help is appreciated.First of all, thanks for taking time to look at my message. Here is how my message-resources tag look like in struts-config.xml file:
<message-resources parameter="ApplicationResources"/>
The "ApplicationResources.properties" file exist in the WEB-INF folder of my application and following are the entries in that file that i think are relevant:
errors.header=<h3><font color="red">Validation Error</font></h3>You must correct the following error(s) before proceeding:<ul>
errors.footer=</ul><hr>
error.username.required=<li>Username is required</li>
Is there anything else needed to go into resource file? Or should i put my resource file somewhere else? -
Help with Reading values from static table in a .pdf file
Hi guys,
Pls try to clear this doubt of mine.
I basically have 2 files. Both are .pdf extension and they have tables in them. I need to compare certain values in one file with the corresponding values in the other table in the second file.
I need to do this programatically in c# . net
I have tried using packages like pdfbox and stuff which convert the pdf file into text. But cant I get the table as an object or something using which I can access the required rows and columns?
Also, these tables are static information. They are not a part of a form or anything like that.
Please help me with this.
Thanks.The document is corrupt. Try a backup.
