How do i put the result of a sum in a variable ?

Hi All...
I have two columns in my template, one is debit and another one is credit...
I did a sum in debit column and a sum in the credit column...
Now i need to subtract the sum of debit from the sum of credit,
i was thinkin about put these results in a variable (something like make a "sumResultA" and "sumResultB" and make a field like this <?((sumResultA) - (sumResultB))?>...
so... how do i put the result of a sum in a variable ???

<?xdoxslt:set_variable($_XDOCTX, 'variablesumResultA', (sumResultA))?>
<?xdoxslt:set_variable($_XDOCTX, 'variablesumResultB', (sumResultB))?>
<?xdoxslt:set_variable($_XDOCTX, 'variablesumResultAB', ((sumResultA) - (sumResultB)))?>to set the, use as above.
to display them
<?xdoxslt:get_variable($_XDOCTX, 'variablesumResultB')?>
<?xdoxslt:get_variable($_XDOCTX, 'variablesumResultA')?>
<?xdoxslt:get_variable($_XDOCTX, 'variablesumResultAB')?>

Is it possible to put the results from a query in a variable to use in the bean class?

Hello, I'm using JDeveloper 12.1.2.0.0
I would like to keep the result of my queries (the method i created in the AppModule) in a RichTable or other type of variable so i can have the results stored and i don't have to do unnecessary queries after. I don't think the query is the problem but keeping the results.
I've tried to do that by using this:
    public String testVFactSales(String conditions) {
        PreparedStatement query = getDBTransaction().createPreparedStatement("" + "select * from v_fact_sales " + conditions, 0);
        //ResultSet rs;
        ResultSet result;
        //RichTable result;
        //String result = null;
        try {
            //query.setString(1, conditions);
            // query.execute();
            query.execute();
            result = query.getGeneratedKeys();
            query.close();
            System.out.println("Result: " + result.toString());
            return result.toString();
        } catch (SQLException e) {
            e.printStackTrace();
        return "";
As you can see, i've already tried some solutions but so far i only get errors (cannot convert or null exception, when i try to put the result in a richtable in my bean class)
Any ideas?
This is very important for me, since it would improve the performance of my project a lot.

Frederico.

How do i put the results from a calculation as the offset value

hi .. i am trying to set the value of the mask offset from the results i get from a calculation.
this is what i am trying to do
i want to get a ROI from an image, so i used thresholding to separate it form the background
then i find the centroid of the image. i then create a mask a little
larger than the ROI to get rid of the background in an unthresholded
image but the position of the mask is at origin(0,0)
i need the centroid of the mask to be the same as the ROI. so i
subtract the x and y values of the ROI centroid with the centroid of
the mask to get the offset. which is done manually. but i want to
do it for ROIs in different positions, so i want to get the value of
the subtraction staight into the VI .. how can i do that..?? i tried
wiring the value of subtraction into the input of the "set offset" node
but it does not work .. can anyone help me ??thanks very much

i managed to get it done...i did not know how about the cluster to element function .. could you comment on my program?
i'm trying to construct a sign language translator. for the
signing. i am using yellow colored gloves with colored finger tips. the
yellow region is to help me detect the position of the gloves during
thresholding.
1st of all .. i do thresholding to separate the ROI from the
background.. then i put a bouding box around the region of interest. is
there any better and easier way to do this??
could anyone point me in the right direction ?
i am very new to LV and image processing. i always have problem
using some functions especially when it requires lots of settings.
sometimes the help file does no help much ..
my next problem after creating the bounding box is how do i extract
only the colors from the image? i tried color thresholding but the
result is gray scale. how do i extract only the yellow region of the
gloves and the finger tips to be further processed? in MATLAB , color
segmentation is used.. but i can't figure how it works in LV .. please
help me .. thanx

How do I create a 1d array that takes a single calculation and insert the result into the first row and then the next calculation the next time the loop passes that point and puts the results in thsecond row and so on until the loop is exited.

The attached file is work inprogress, with some dummy data sp that I can test it out without having to connect to equipment.
The second tab is the one that I am having the problem with. the output array from the replace element appears to be starting at the index position of 1 rather than 0 but that is ok it is still show that the new data is placed in incrementing element locations. However the main array that I am trying to build that is suppose to take each new calculation and place it in the next index(row) does not ap
pear to be working or at least I am not getting any indication on the inidcator.
Basically what I am attempting to do is is gather some pulses from adevice for a minute, place the results for a calculation, so that it displays then do the same again the next minute, but put these result in the next row and so on until the specifiied time has expired and the loop exits. I need to have all results displayed and keep building the array(display until, the end of the test)Eventually I will have to include a min max section that displays the min and max values calculated, but that should be easy with the min max function.Actually I thought this should have been easy but, I gues I can not see the forest through the trees. Can any one help to slear this up for me.

I didn't really have time to dig in and understand your program in depth,
but I have a few tips for you that might things a bit easier:
- You use local variables excessively which really complicates things. Try
not to use them and it will make your life easier.
- If you flowchart the design (very similar to a dataflow diagram, keep in
mind!) you want to gather data, calculate a value from that data, store the
calculation in an array, and loop while the time is in a certain range. So
theres really not much need for a sequence as long as you get rid of the
local variables (sequences also complicate things)
- You loop again if timepassed+1 is still less than some constant. Rather
than messing with locals it seems so much easier to use a shiftregister (if
absolutely necessary) or in this case base it upon the number of iterations
of the loop. In this case it looks like "time passed" is the same thing as
the number of loop iterations, but I didn't check closely. There's an i
terminal in your whileloop to read for the number of iterations.
- After having simplified your design by eliminating unnecessary sequence
and local variables, you should be able to draw out the labview diagram.
Don't try to use the "insert into array" vis since theres no need. Each
iteration of your loop calculates a number which goes into the next position
of the array right? Pass your result outside the loop, and enable indexing
on the terminal so Labview automatically generates the array for you. If
your calculation is a function of previous data, then use a shift register
to keep previous values around.
I wish you luck. Post again if you have any questions. Without a more
detailed understanding of your task at hand it's kind of hard to post actual
code suggestions for you.

How to merge text files and put the result in a text file.

Hi,
I am trying to merge the files(text) using OWB and I would like to put the result in a file. Could any one please explain how to do this.
Thanks and regards
Gowtham Sen.

using the unix commnad 'cat' along with the redirect '>>' will concat the files into one target
#this will create the target file and over-write it if it existed already
cat file1 > target
##Now add the rest of the files to the target, without over-writing
cat file2 >>target
cat file3 >>target
cat file16 >> target
You can then use an external table on the target file.
A nicer way would be to user a 'for loop', but this will work fine.

HT201263 how do i put the ipod in recovery mode

How do i put the ipod in recovery mode so that i can unlock it... Thank you

If You Are Locked Out Or Have Forgotten Your Passcode or Just Need to Restore Your Device
iTunes 10 for Mac- Update and restore software on iPod, iPhone, or iPad
iPhone, iPad, iPod touch: Wrong passcode results in red disabled screen
iOS- Understanding passcodes
     If you have forgotten your Restrictions code, then follow the instructions
     below but DO NOT restore any previous backup. If you do then you will
     simply be restoring the old Restrictions code you have forgotten. This
     same warning applies if you need to restore a clean system.
A Complete Guide to Restore or Recover Your iDevice (if You Forget Your Passcode)
If you need to restore your device or ff you cannot remember the passcode, then you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and re-sync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.
Try restoring the iOS device if backing up and erasing all content and settings doesn't resolve the issue. Using iTunes to restore iOS devices is part of standard isolation troubleshooting. Restoring your device will delete all data and content, including songs, videos, contacts, photos, and calendar information, and will restore all settings to their factory condition.
Before restoring your iOS device, Apple recommends that you either sync with iTunes to transfer any purchases you have made, or back up new data (data acquired after your last sync). If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.
Follow these steps to restore your device:
     1. Verify that you are using the latest version of iTunes before attempting to update.
     2. Connect your device to your computer.
     3. Select your iPhone, iPad, or iPod touch when it appears in iTunes under Devices.
     4. Select the Summary tab.
     5. Select the Restore option.
     6. When prompted to back up your settings before restoring, select the Back Up
         option (see in the image below). If you have just backed up the device, it is not
         necessary to create another.
     7. Select the Restore option when iTunes prompts you (as long as you've backed up,
         you should not have to worry about restoring your iOS device).
     8. When the restore process has completed, the device restarts and displays the Apple
         logo while starting up:
           After a restore, the iOS device displays the "Connect to iTunes" screen. For updating
          to iOS 5 or later, follow the steps in the iOS Setup Assistant. For earlier versions of
          iOS, keep your device connected until the "Connect to iTunes" screen goes away or
          you see "iPhone is activated."
     9. The final step is to restore your device from a previous backup. If you do not have a
          backup to restore, then restore as New.
If you are restoring to fix a forgotten Restrictions Code, then skip Step 9 and restore as New.
If you really do need to put it in recovery mode (DFU):
Placing your device into recovery mode:
Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.
   1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the
       other end of the cable connected to your computer's USB port.
   2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds
       until the red slider appears, then slide the slider. Wait for the device to turn off.
              * If you cannot turn off the device using the slider, press and hold the
                Sleep/Wake and Home buttons at the same time. When the device turns off,
                release the Sleep/Wake and Home buttons.
3. While pressing and holding the Home button, reconnect the USB cable to the
       device. The device should turn on. Note: If you see the screen pictured below,
       let the device charge for at least ten minutes to ensure that the battery has some
       charge, and then start with step 2 again.
4. Continue holding the Home button until you see the "Connect to iTunes" screen.
       When this screen appears you can release the Home button:
5. If necessary, open iTunes. You should see the following "recovery mode" alert:
6. Use iTunes to restore the device.
If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Additional Information:
Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.

How do I put the music on my IPod onto the ITunes on my new computer? Help

Just got a new computer. How do I put the music, ect. on my IPod onto the ITunes on the new computer?
I downloaded ITunes onto the new computer, plugged in my Ipod, and a box popped up asking to either erase or transfer what was on my Ipod. I'd read before we put up the new computer that all you have to do is click the Transfer button and it will put all the music, ect. onto the ITunes account. Well, it didn't work. The page where it shows the bar that shows the memory is on the ITunes and shows exactly what it did on the old computer, but that's it. There's no music, nothing. I logged on to my ITunes account, that did nothing. What can I do? There has to be SOMETHING. Thanks so much!

1). Connect your iPod to your new computer. When you get the message that it is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all the songs from your iPod.
2). When your iPod appears in the iTunes source list change the update setting to manual, that will let you continue to use your iPod without the risk of accidentally erasing it. Check the "manually manage music and videos" box in Summary then press the Apply button. Also when using most of the utilities listed below your iPod needs to be enabled for disc use, changing to manual update will do this by default: Managing content manually on iPod and iPhone
3). Once you are connected and your iPod is safely in manual mode there are a few things you can do to restore your iTunes from the iPod. iTunes will only let you copy your iTunes Store purchases directly from an iPod to the computer, you'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer
For everything else (music from CDs, other downloads and including iTunes purchased songs and in some cases, videos and games) there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod. You'll find that they have varying degrees of functionality and some will transfer movies, videos, photos, podcasts and games as well. You can read reviews and comparisons of some of them here:
Wired News - Rescue Your Stranded Tunes
Comparison of iPod managers
A selection of iPod to iTunes utilities:
TuneJack Windows Only (iPhone and iPod Touch compatible)
SharePod Windows Only (iPhone and iPod Touch compatible)
iPod2PC Windows Only
iDump Windows Only
YamiPod Mac and Windows
iPod Music Liberator Mac & Windows
Floola Mac & Windows
iPodRip Mac & Windows (iPhone and iPod Touch compatible)
iPod Music Liberator Mac & Windows (iPhone and iPod Touch compatible)
Music Rescue Mac & Windows (iPhone and iPod Touch compatible)
iGadget Mac & Windows (iPhone and iPod Touch compatible)
iRepo Mac & Windows (iPhone and iPod Touch compatible)
iPod Access Mac & Windows (iPhone and iPod Touch compatible)
TouchCopy Mac & Windows (iPhone and iPod Touch compatible)
There's also a manual method of copying songs from your iPod to a Mac or PC. The procedure is a bit involved and won't recover playlists but if you're interested it's available on page 2 at this link: Copying Content from your iPod to your Computer - The Definitive Guide
4). Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync.
5). I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these days, you can get loads of storage for a reasonable outlay: Back up your iTunes library by copying to an external hard drive

Just a thought...I suggest to use XSLT for doing these type of formatting. Its more flexible to get XML for te query columns and then define the formatting at XSLT level. This way you dont have to keep changing the procedure or query. Just XSL change will do the job..

   How can I put the report generated by a program into a File?It can be in TXT format or excel format which ever is possible.
I need to export this file to memory,How can I do that??

Shashank.

Hello Shashank,
Please ignore my previous answer... Ofcourse it works...
There are several ways to do this...
two of them are
1. List -> Save -> File and press enter..
    it will ask for the format, then path where to save it. Just give the path.
2. Using function module 'GUI_DOWNLOAD'.
I'm giving the example bellow which explains the usage of both GUI_UPLOAD and GUI_DOWNLOAD.
To do this... you need to have folder with name 'TEST' and a .txt file in it with name 'test'. And contents of it are :
TEST1             ,BOT
TEST2             ,BOT
TEST3             ,BUT
with spaces.

   filetype                      = 'ASC'
TABLES
    data_tab                      = g_t_itab.
Now you will get one .txt file with name 'TEST1.TXT' in the TEST folder.

like how do i put the two language flag toggles such that you can choose to read the site in russian or english?

On each of the English pages add a Russian flag and link that flag to the Russian equivalent page with the Inspector/Link/Hyperlind pane.
On each of the Russian pages add a US or British flag and link that flag to the equivalent English page.

I've recently formatted my 10.7.4 mountain lion MacBook from 2007. The hard drive is wiped and I think it deleted to OS too. How do I put the OS back on it?

I've recently formatted my 10.7.4 mountain lion MacBook from 2007. The hard drive is wiped and I think it deleted to OS too. How do I put the OS back on it?

Wiping the drive does indeed delete the OS. Try this -
Boot to the Lion (10.7.4 is Lion not Mountain Lion) recovery partition by restarting the computer and holding down the command and R keys during startup.
If this works, reinstall from here. You must be connected to the Internet to do this.
If this does not work, possibly because you reformatted the recovery partition as well, you will need to reinstall from your original disks (assuming it came with 10.6 or earlier.) Boot to the disk by holding down the C key during startup and run the installer.
Best of luck.

I had my computer worked on and did not back up my itunes library. how do i put the songs on my ipod back to the itunes library

I had my computer worked on and did not back up my itunes library. Now the only music I have is on my ipod. How would I put the music on my ipod back into my itunes music library?

The music sync is one way - computer to ipod.
The exception is itunes purchases: File>Transfer Purchases
You should always maintain a backup copy. This is very important.
