Can not understand ADF code example

Hi all
I am trying to learn the tutorial Oracle ADF, but I do not understand this loop:

public Integer getNextLineItem() {}
int maxLineNo = 0;
for (ServiceHistories
{:GetServiceRequests().getServiceHistoriesCollection())} SVH
If (svh.getLineNo ()! = null) {}
int testLineNo = svh.getLineNo () .intValue ();
If (testLineNo > maxLineNo) {}
maxLineNo = testLineNo;
}
}
}
return ++ maxLineNo;
}

Hello

It is always best to display the required information, while displaying issues.

1. version JDeveloper.
2. the link to the tutorial that you use.

The initial appearance, the code finds a row in the ServiceRequests table (as a collection) and gets the linenumber column. Check its value and returns the line COMP + 1 max.

    I have photos I want to decrease the dpi on but can not understand how with the Gallery Windows. I have Windows Vista operating system.

    ===============================================
    You can resize a picture in WLPG but if you want to change the .dpi you
    need a different application.

    Information about resizing...
    Right-click on one or more selected inches... Choose... "Resize" in the menu.
    Choose a format, access a folder to save in the left click the ' resize and
    Save "button. (I suggest that you save the photos resized in a new folder
    to prevent the replacement (replacement) the originals)

    Take a look at the following link:

    http://blogs.msdn.com/PIX/archive/2007/11/30/resizing-photos-in-Windows-Live-Photo-Gallery.aspx

    In addition, the free software IrfanView can change dpi. Simply open a photo in IrfanView
    and go... Image / information. Enter the resolution you want in the resolution
    fields and on the left, click change. Then go to... File / save as... and save

  • Vista: The device can not start (error Code 10) for a USB CDC device which works fine in XP

    I have a USB device 2.0 DCC which works very well under all of our Windows XP machines, but not based on Vista.  The device uses the usbser.sys driver and emulation of the virtual Comm Port.

    The text of the listing shows the same information on Xp and Vista, except under vista it shows no open pipes.  Shows Device Manager: device can not start (error Code 10).

    Using Vista I can't connect to the vista of CDC through concentrators or device to any other device wireless hub except for a Dlink Wireless hub, which has a layer of software between the CDC device and the PC.  With Xp, it all works very well on more than one PC, with Vista, there are questions.  I use the INF manufacturer provided for Vista, still no results.

    Any ideas on this would be greatly appreciated.

  • Where can I find the code example to download...

    At one point there is by setting my BB with Eclipse dev environment, several months I had stumbled on a link where you can download some sample code. It includes items such as the demo of socket and a little more.

    I have looked at the links at the top of the forum and cannot find this link. It might be good to display in the header of the forum with others, unless I'm completely blind and missed.

    Anyone got the link to examples of BB code?

    Thank you.

    I use Eclipse for development - using the plugin. I had not thought looking in the directories of the plugin to find the source code. It's a bit unexpected.

  • a movie clip button can not detect its code AS

    On my root timeline code below making reference to a movie clip button, which can not be detected when I place my mouse over it. He was given an instance name. I don't know why it works. I've done other buttons in the same way and they work. It only works when I put my code in the timeline of binary_mc, which I don't want to do what I want to keep all my centralized code.

    Any ideas?

    It seems to me that your BACK button doing eaxctly what you tell it to. You should try to follow logically what you ask.

    For your next button, you have a "_root." stuck in itself that is a typo and should be deleted. Your next button is also exactly what you ask him. He actually goes to the _binaryToDenaryPage of tag part two where he runs the script on chassis # 469, that is which then sends you back to the main menu.

    It would be useful to you if you could debug your slightly better FLA and try ways of his actions. For example, try to comment on all the ACEs on chassis 469 with the exception of the stop();

    You assume that your button script does not work because they do not seem to do what you ask them, but it is only appearance. If you are looking for the needle in a haystack badly.

    I also noticed that in 469, you reference several image tags that do not exist as _B2D3 and _B2D2. I tried to change those for labels, I think that you mean and now my Flash crashes whenever I try to test your movie so I gave up.
