How to get only one character

my problem is the following:
i want to get only ONE character from the input without pressing the "enter"-key. for example pressing ESC and doing something because it is ESC hit.

You can't. Either use a GUI or create a JNI DLL function that calls getch ().

How to get only one line between tables in database diagram?

Hi!
I'm using jdev 10.1.3. I've got a database schema with a lot of tables. I would like to have them in one database diagram in compact view with only ONE line between two tables even if there are more foreign key columns between the two tables. In the shema there are a lot of foreign keys with multiple columns and the diagram is hard to read.
How to archieve this?
Thanks,
Carsten.

hi,
u should use the same variable across all your queries.In the WAD there is a propoerty "display same variable once". Check that.

Enlarging a volume
If you have multiple volumes on a disk and one is running out of space, you may be able to enlarge it
without losing any of its data.
To enlarge a volume, you must delete the volume that comes after it on the disk, and then move the
volume’s end point into the freed space. You can’t enlarge the last volume on a disk. You can see the
order of the volumes in Disk Utility by selecting the disk, clicking Partition, and looking at the Volume
Scheme list.
All data on the deleted volume will be erased. Be sure to back up your disk’s data before you begin.
To enlarge a volume:
From the list at the left, select the disk that contains the volume you want to enlarge, and then click
Partition.
In the Volume Scheme list, select the volume beneath the volume you want to enlarge, and then click
Delete〔-〕.
The volume is immediately erased, leaving the space it formerly occupied available.
Resize the volume.
You can drag the divider at the bottom of the volume in the Volume Scheme list, or you can select the
volume, and then enter a value in the Size field.
If the enlarged volume doesn’t use all the space from the deleted volume, you can create new volumes
in the unused space.
To create a new volume, click Add〔+〕, select the new volume, and choose its name, format, and size.
Click Apply.
Disk Utility enlarges the volume and creates any new volumes.

How to get only one record per machine

I have this SQL statement that works.

WHERE
cn.Model0 LIKE '%780%'
ORDER BY

The problem is whent his runs it returns multiple rows for each serial number/machine it finds. So I'll have 5 or 6 rows for the exact same machine. How do I make it only give me 1 row for each serial number/machine?
mqh7

... because you added v_GS_PARTITION gs (which results in multiple rows per resource) and then you are doing the inner join blues.
This should be better:
SELECT
cn.Name0 AS [Computer Name],
cn.Model0 AS [Model],
cn.Manufacturer0 AS [Manufacturer],
bios.SerialNumber0 AS [Serial Number],
rs.Operating_System_Name_and0 AS [OS Type],
--ld.FreeSpace0 AS [Free Disk Space],
--ld.Size0 AS [Actual Disk Size],
x86.TotalPhysicalMemory0 AS [Total Memory],
aa.SMS_Assigned_Sites0 AS [Assigned Site]
FROM
v_GS_COMPUTER_SYSTEM cn
-- INNER JOIN v_GS_LOGICAL_DISK ld on cn.ResourceID = ld.ResourceID
--INNER JOIN v_GS_PARTITION gs ON cn.ResourceID = gs.ResourceID
INNER JOIN v_GS_X86_PC_MEMORY x86 ON x86.ResourceID = cn.ResourceID
INNER JOIN v_R_System rs ON rs.ResourceID = cn.resourceID
INNER JOIN v_GS_PC_BIOS bios ON bios.resourceID = cn.ResourceID
INNER JOIN v_RA_System_SMSAssignedSites aa ON aa.ResourceID = cn.ResourceID
WHERE cn.Model0 LIKE '%780%'

How to get page one to animate only once in interactive pdf?

how to get page one to animate only once in interactive pdf? I like when the document opens up in acrobat and the the page animations work but when I go to one of the pages and hit my designated home button it goes back to page one but it reloads again. As a user it would drive me crazy to have to wait for all of it to load......anyway to have that page one load once as the opening page?

I don't think you really mean animations (unless you have a placed SWF file) because things created with the Animation panel don't work in PDF. Nonetheless, you're talking about some kind of interactivity which is set to happen On Page Load.
So when you return to that page, of course the interactivity loads again.
There isn't a On Page Load Once command.
Perhaps you need to rethink why the interactivity is there. If it's important, maybe it should be triggered by a rollover or by clicking a button.

I have Office 2011 which includes Word. Ever since downloading Mavericks, when I try to send a two-page word document, some recipients get only one page. Also sometimes when I burn an image from iPhoto on to a disc, only part of the image appears. Why?

I have Office 2011 which includes Word. Ever since downloading Mavericks, when I try to send a two-page Word document by email, some recipients get only one page. Also when burning an image from iPhoto (usually no larger than 1mb) on to a disc, only part of it appears. It appears to have been magnified so that only a part of the image appears. Can anyone enlighten me as to what is happening? And how to fix it??

Have you tried
table.getColumn(0).setCellEditor(new DefaultCellEditor(new JFormattedTextField("[A-Z]")));
I haven't tried it. You might look at some of these.

How to get only current exception message from tables

Hi
In my sceanario , I want to have the list of Current MRP exception messages list from table
I understand that MRP detailed lists, including all exception messages, are stored in transparent table MDKP and cluster table MDTC.
I can tell ABAPer to write a report for me , to read the data from these tables , but I guess these tables contain old exception message also , which are not currently appearing in MRP list
How to get only current exception message
Rgds,
sandeep

Sandeep,
MDTC contains only data from the most recent MRP run. So, all messages you see are those which are currently valid.
The messages might have first appeared during a previous run, but they still need to be addressed.
Before you invest a lot of time and effort into writing and debugging a custom report, you should probably try to use the standard SAP functionality found in MD06. On the Processing indicator tab, you can select "Only with new exceptions". Here you can tag a material/plant as 'processed', and thereafter, the exceptions that existed there before you tagged the part will not be re-displayed.

How to get only the first result in extract function

v_result := p_response.doc.extract('//'||p_name||'/child::text()').getstringval();
if i have 5 responses like '100','100',100','200','200' e get '100100100200200' and i want only '100'.
thanks in advance

Two ways .....
1. Use Javascript E4X instead ...there are nice functions for getting children of parents.
2. Cycle through all of the form1.nodes and look for objects that have a className of "subform". For loops are useful for this task.
Make sense?
