How to use JavaBeans when the number of inputs is variable

I have a problem. The number of textboxes in a HTML form is read from a database. How can I avoid reentry from users? Is it possible to use JavaBeans or may be there is some other way? Thanks in advance.

Well, I meant that when a Jsp page is generated the number of textboxes is read from the database. So it it is apriory unknown. But I have found a solution to this problem: create a bean of String type for each textbox. Thanks.

How-to use Excel for the XML file input?

Hello all,
Following our discussion with Gerhard Steinhuber on the very nice tutorial from Horst Schaude , "How to upload mass data via XML File Input" , I am starting this new discussion.
In the comments section of this previous cited tutorial, Rufat Gadirov explains how to use a generated XML from Eclipse instead of your XSD file as your source in Excel.
However, in spite of all the instructions, I am still facing the same issue in Excel when I try to save my file as XML : "The XML maps in this workbook are not exportable".
What I try to do is to create one or more Sales Orders with multiple Items in it from a XML File Input, using excel to enter data.
The part with the File input is working (if I directly upload my file to the webDAV, it creates a sales order instance with multiple items).
The only missing part is the Excel data input that I cannot make work. Any help on this matter would be greatly appreciated.
Here is my XML file that I try to use as a source in Excel before inputing data from Excel:
<?xml version="1.0" encoding="UTF-8"?>

Hello Jacques-Antoine,
I suppose that as you have tried to construct a map from the schema, you have taken the elements from the List level down. In this case I also can't export the map.
But if you take the elements from the level MySalesOrderUploaded down, you'll get the exportable map (screenshots)

How To Get rid of Exponential format in datagridview when the number is very large

When the number is very large like :290754232, I got 2.907542E +08. in datagridview cell
I using vb.net , framework 2.0.
how can I get rid of this format?
Thanks in advance

should I change the type of this column to integer or long ?
The datagridview is binded to binding source and a list ( Of).
Mike,
I'll show you an example that shows the correct way to do this and a another way if you're stuck using strings in exponential format. The latter being the "hack way" I spoke about Friday. I don't like it, it's dangerous, but I'll show both anyway.
In this example, I'm using Int64 because I don't know the range of yours. If your never exceeds Int32 then use that one instead.
First, I have a DataGridView with three columns. I've populated the data just by creating longs starting with the maximum value in reverse order for 100 rows:
The way that I created the data is itself not a great way (there's no encapsulation), but for this example "it'll do".
Notice though that the third column (right-most column) isn't formatted at all. I commented out the part that does that so that I could then explain what I'm doing. If it works, it should look like the first column.
The first column represents an actual Int64 and when I show the code, you can see how I'm formatting that using the DGV's DefaultCellStyle.Format property. That's how it SHOULD be done.
The third column though is just a string and because that string contains a letter in it, Long.TryParse will NOT work. This is where the "hack" part comes in - and it's dangerous, but if you have no other option then ...
You can see that now the third column matches the first column. Now the code:
Option Strict On
Option Explicit On
Option Infer Off

On my iPad home screen, the mail app used to indicate the number of new emails I had with a number in a red circle. This has vanished since I upgraded. Does anyone know why, and how to restore this?

On my IPad 2 home screen, the mail app used to indicate the number of new messages with a number in a red circle, next to the app. This has vanished, I think about the same time as when I upgraded to the new OS. Does anyone know why and how to restore this feature?

Thanks. While you were replying to my question, I went into notifications and figured

With a PDF Dynamic form using show/hide actions, how to ensure that when the completed form is saved, closed and re-opened, the form still show the fields as before it was closed?
I have developed a form with fields hidden by default, that become visible based on box ticked or radio button selections.
My problem is that, when I close the form and re-open it, it comes back to it's default presentation, regardless of the information already recorded in the form (including in the now hidden fields.
How to correct that
Thanks in advance for any hint you can provide.

I've had the same problem. This solved it...
Go to the "Form properties..." in the File-menu. Select "Run-time" to the left and in the box "Scripting" Preserve scripting changes to form when saved: choose Automatically (Script-based state changes are saved locally in an insecure fashion. This option cannot be used for certified forms).
Hope it works for you to...

In my numbers when I click on a cell it shows the formula but what I want ot see is the number I input inot the cell. what did I do and how can I change it?

In Numbers, when I click on a cell I see the formula, how do I see the number I input inot the cell?

Gerald,
A cell either contains:
1) what you typed (or entered) OR
2) the result of a formula
to enter a formula, select a cell, then type the "=" sign then the formula, then enter
to enter a number oer text, then type the number(s) or text you want, then the enter key
the contents of a cell is the last thing you typed into that cell. If there was a formula, then selecting the cell and typing will result in losing the formula.
B3 will change as you modify the cell contents in B1 and B2

I have a friend who just got a cell phone but it's not an iPhone but the person who use to have the number she got had or has an iPhone, I can't message my friend, the messages go out as iMessages and go to the other person. Is there a way to fix this

I have a friend that just got a new cell phone, it's not a iPhone, but the person that use to have the number that she got did! I can't message my friend, they go out as iMessages to the other person! How can I fix this without turning all my iMessages off?

She needs to call the carrier on her old iPhone and have it removed from her account.
Once she does that you will not be able to use iMessage because that only works Apple to Apple.
You will need to use something else like Skype instead.

How do I know when the buffer flushed all the data out?

I am using a very high sampling rate (500000 Hz) and acquire 1024 data points continuously. It takes 370000 data points in 10 second. I use a counter to help with the retrigger PFI line. I have a huge buffer so that I can make sure that the buffer is not overflowed. The code is attached below. My problem is that the data acquisition is done so fast (in 10 seconds) but the processing of the data is not. In :nEvent, I basically save and plot the data. The saving process is not slow. However, our videocard is so SSSSLOOOW and can not keep up with realtime data display. After the user is done collecting the data, they do not want to wait for the screen to plot the data from the buffer. So after the data collection is done, I basically stop the plotting process but we still need to flush the data out from the buffer for saving. My question is that how can I tell when the buffer is empty.
Thanks,
Yajai

Yajai,
I'm a little confused about your acquisiton. Do you intend for it to be
finite, or continuous? I'm also unclear about your rates. You state
that you are acquiring 1024 samples at 500kHz, yet you get only 370k
samples in 10 seconds. Are you periodically acquiring 1024 samples at
500kHz? Do you do any reads other than the final m_reader->ReadMultiSampleAsync(samplesPerChannel, m_data)? Could you provide the code where you stop the plotting process?
Thanks,

How to use shortDesc in the disabled inputtext

hi,all
i encounter a problem,our team must use disabled inputtext when the text is only used to output string.
the reson we don't use outputext is if there is noting in the outputtext,there is nothing displayed.
how to use shortDesc in the disabled inputtext?
here is the code:
<af:inputText value="#{bindings.shortdesc.inputValue}" disable="true"
id="ot2" columns="25" shortDesc="#{bindings.longdesc.inputValue}"
simple="true"/>
thanks all

Hi,
........... I use JDev 11g ..............
If you make your inputText disabled -----> shortDesc will not be displayed.
You can make a workaround to achieve this by using popup as :
1- add showPopupBehavior inside your inputText as :
<af:inputText label="label1" id="it1" disabled="true">
                <af:showPopupBehavior triggerType="mouseOver"
                                      align="endBefore" alignId="it1"
                                      popupId="p1"/>
              </af:inputText>2- add a popup which will display your shortDesc text
<af:popup id="p1">
                  <af:outputText value="Sameh POPUP" id="ot1"/>
          </af:popup>I hope it is useful.

How to use case when function to calculate time ?

Dear All,
May i know how to use case when function to calculate the time ?
for the example , if the First_EP_scan_time is 12.30, then must minus 30 min.
CASE WHEN FIRSTSCAN.EP_SHIFT <> 'R1' AND FIRSTSCAN.EP_SHIFT <> 'R2'
THEN ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF((CASE WHEN SHIFTCAL.EP_SHIFT = 'N1'
THEN CONVERT(VARCHAR(8),DATEADD(DAY,+1,LEFT(FIRSTSCAN.EP_SCAN_DATE ,8)),112) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','')
ELSE LEFT(FIRSTSCAN.EP_SCAN_DATE ,8) + ' ' + REPLACE(CONVERT(VARCHAR(8),DATEADD(HOUR,+0,SHIFTDESC.EP_SHIFT_TIMETO + ':00'),108),':','') END),12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0 - 0.25) AS FLOAT),2)
ELSE ROUND(CAST((DATEDIFF(MINUTE,CAST(STUFF(STUFF(FIRSTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME),CAST(STUFF(STUFF(LASTSCAN.EP_SCAN_DATE,12,0,':'),15,0,':') AS DATETIME)) / 60.0) AS FLOAT),2) END AS OTWORK_HOUR

Do not use computations in a declarative language. This is SQL and not COBOL.
Use a table of time slots set to one more decimal second of precision than your data. You can now use temporal math to add it to a DATE to TIME(1) get a full DATETIME2(0). Here is the basic skeleton.
CREATE TABLE Timeslots
(slot_start_time TIME(1) NOT NULL PRIMARY KEY,
slot_end_time TIME(1) NOT NULL,
CHECK (start_time < end_time));
INSERT INTO Timeslots --15 min intervals
VALUES ('00:00:00.0', '00:14:59.9'),
('00:15:00.0', '00:29:59.9'),
('00:30:00.0', '00:44:59.9'),
('00:45:00.0', '01:00:59.9'),
('23:45:00.0', '23:59:59.9');
Here is the basic query for rounding down to a time slot.
SELECT CAST (@in_timestamp AS DATE), T.start_time
FROM Timeslots AS T
WHERE CAST (@in_timestamp AS TIME)
BETWEEN T.slot_start_time
AND T.slot_end_time;
