How to change properties dinamically to all objects that are in a JPanel

Hi experts!
I have this code:
JPanel pnlDataTxt;
pnlDataTxt.add(new JTextField());
But I want to change the properties of that JTextField after it has been added to the JPanel.
How can I do that??

Hi experts!
I have this code:
JPanel pnlDataTxt;
pnlDataTxt.add(new JTextField());
But I want to change the properties of that JTextField
after it has been added to the JPanel.
How can I do that??You have to create a handle to an instance of an object like:
JTextField testField = new JTextField();
JPanel pnlDataTxt;
pnlDataTxt.add(testField);Now you can change the properties of "testField".

Changing the Owner of all Objects in Instance ?

How to Change the Owner of all Objects in Instance, like for example the Procedure: sp_changedbowner in an MS-SQL-Database, who changed the Owner of the actual Database !
I'am looking for another possibility to do it by export the Datbase and import as new Owner !

Hi Laurent Schneider
OCM DBA, I successfully run:
connect SYS/&2 as SYSDBA;
Update sys.obj$ set owner#=(Select USER# from sys.user$ where NAME = '&4')
where owner#=(Select USER# from sys.user$ where NAME = '&3');
commit;
Afterwards I dropped the &3 User CASCADE and then created the &3 User with less rights ! Before Update-Command the &4 User shouldn't be the Owner of any Object ! At Last I'm not sure that is the right way ?!

How to change original source system of objects at one time

Hi, experts !
I installed extra devlopment server using system copy of orignal
delveopment system.
We have planed that new objects applied to orginal server after developing
finished on extra devlopement server.
The problem is we can not modify or add old objects for specific
package because orignal source system is different
and I know this is SAP policy.
Of course original source server can be changeed on t-code SE03 or
function module TRINT_TADIR_MODIFY
but it should be applied to every objects. This is big job to BC admin.
Is there any solution to possible it at one time?
Best Regards

You can transport all relevant packages from the old to the new development box including a change of the original system using a special transport request of type "relocation of complete package". Check with your system administrators.

How to Change Finder Settings in All Windows?

Hi All,
Similar to the original post found here: Re: How to Change View Options for ALL Finder Windows?
I'm trying to change my finder settings across all finder windows... I tried the solution posted in the above thread but get this message in terminal. I'm not all that computer savvy when it comes to terminal so not sure what it means... Perhaps someone knows of a different and/or better solution?
Any help would be much appreciated, thanks and take care!
Dave

Yup got it back after waiting, followed the remaining directions, but didn't work for me... not sure why? Upon rebooting folders do not change after I readjust settings and click 'use as default'.... strange... I even tried that other line of code another person posted later on in the previous thread.

How to change the title of an object in the build order window?

If an internal ID is changed for the Work Repository how does it affect objects that are already in it? Will they continue to run or do you need to cycle the ODI agent?

I was having trouble migrating the Master and Work repositories from my QA to my Prod environment. I was getting an error message that the internal id's were alike so I changed the internal id in my Prod Master repository. Then I tried to migrate the Work repository and was getting a similar error. I did a search on the internet for the error message and it recommended that I renumber the Work repository so I did. My concern now is how these changes affect the objects that are already in the repositories? Will those objects continue to run? Also do these changes take affect immediately or do you need to cycle the ODI agent?

Well I cannot completely assure you but so far I have not faced any issues after a renumber. It will affect the exist object only when you have imported the object in synonym_update mode. I believe you have the daily backup of your production repository.

So, i have bad news for you : you'll have to rebuild again.
Meanwhile i have excellent news for you : there's an online tool made by Johannes Henseler called Sidecar xml which builds the necessary xml file for you, sort of what you find in the Digital Publishing Folio Editor website, but saves it in your Folio folder.
Next time you import all your folder (with that file), it will place all the necessary information, and even reorder the articles.
Build once, play many times.

Determine all objects that a group has been assigned to

I am trying to determine all objects that a group has been assigned to. For example, I would like to know what communities and portletes a group has been assigned to.
I can retrieve the information directly from the plumtree database, however, I have not been able to determine how to accomplish this via the api.
I have tried the following
IPTObjectManager ptObjMng = ptSession.GetCommunities();
for(inti = 0; i<3;i++)
filter[i] = newObject[1];
filter[0][0] = PT_PROPIDS.PT_PROPID_USERGROUP_GROUPID;
filter[1][0] = PT_FILTEROPS.PT_FILTEROP_EQ;
filter[2][0] = 1634; //group id for my group
IPTQueryResult ptResult = ptObjMng.Query(PT_PROPIDS.PT_PROPID_ALL,-1,PT_PROPIDS.PT_PROPID_NAME,0,-1,filter);
I have verified that the group has been assigned to the community, however, this query returns no records.
How can I retrieve all communities or group that a specific group has been assigned too?
thanks in advance

This sure would be a handy feature! iTunes has it so that you can easily tell which playlists a song is in. It would be convenient for iPhoto as well.

I have CC and while attempting Light Effects, the Light Effects Layer will appear in the layers panel, but the option bar will not appear and neither will the Properties panel. All my preferences are set correct, and my computer has a compatible video card and RAM. Please help!
I tried to delete the layer attempt again. I am in a Photoshop class, but the work is all online, so all my teacher is going to do is send me to this site. I am trying to edit a photo for this class, and without this working, i go to filter>render>light effects. the bar and panel will pop up for about 2 seconds, then disappear. How do i get the options bar and properties panel to display?

I was about to suggest resetting LE from the Workspace drop-down top right corner, but if you can't see the Options Bar, I guess that is not going to happen. The normal Tool reset is grey out for LE, so it might be a case of resetting Preferences.
Reset Preferences
Windows — Hold down Shift Ctrl Alt immediately after starting Photoshop
Mac — Hold down Shift Cmd Opt immediately after starting Photoshop

How to register a callback for cache objects that expire it's TTL?

My scenario is a list of calling telemetry agents, pinging the server with some status. I need to adjust the control rule when devices drop but I need to know what was the device last contribution.
How do I find all the objects that are about to expire without having to periodically vacuum the cache?
Does TTL expiration fire a notification with the existing object (before removing it) to the callback?
If yes what is the filter operation: Remove?

The documentation makes no description on how the duration parameter interacts with notifications.
I tried a sandbox project.
Created a DataCache object.
Register a callback with filter:
DataCacheOperations
filter = DataCacheOperations.RemoveItem;
The callback sends to the Output screen the notifications
public static void OnCacheNotificationReceived(string myCacheName,
string myRegion,
string myKey,
DataCacheItemVersion itemVersion,
DataCacheOperations OperationId,
DataCacheNotificationDescriptor nd)
//display some of the delegate parameters
Debug.WriteLine("A cache-level notification was triggered!");
Debug.WriteLine(" Cache: " + myCacheName);
Debug.WriteLine(" Region: " + myRegion);
Debug.WriteLine(" Key: " + myKey);
Debug.WriteLine(" Operation: " + OperationId.ToString());
Debug.WriteLine("");
Inserted 1 object using a duration of 30 seconds
_cache.Put(key, obj, TimeSpan.FromSeconds(30));
Then sleep 10 minutes:
Thread.Sleep(TimeSpan.FromSeconds(600));
The callback fired about 5 minutes after the Put method.
Here is my config
<dataCacheClient name="default">
<autoDiscover isEnabled="true" identifier="[my role]"/>
<clientNotification pollInterval="30" maxQueueLength="10000"/>
</dataCacheClient>
What I did wrong?

Security Scopes: All instances of the objects that are related to the assigned security roles greyed out

So the guy who built our SCCM server is no longer in the company and his AD account no longer exists. I noticed in SCCM however his account as the "All instances of the objects that are related to the assigned security roles"
is selected. however the option is greyed out for everyone else.
This option is the one found under Administration/Security/Administrative Users select the user and open properties then select the Security Scopes tab.
Is there a way we can provide another user this same level access when we can no longer access through the original build account?
Already looked into tombstone resurrection of his account thats a no go.

Hi,
I recommend you rebuild SCCM or open a case with Microsoft.

How do you dynamically check if all member children are missing?

Hi All,
How do you dynamically check if all member children are missing?
e.g. the below line does not work because you cannot directly use member sets in an IF statement.
IF ((@CHILDREN ("Profit")==#MISSING))
If I explicitly list all children in the IF statement, it will work, but there is alot of hardcoding.
Thanks in advance.
Darren

Hi All,
We have a BSO app and we need to query the account without aggregating the data..
We have 4 accounts sitting under Profit:
Profit
     A001
     A002
     A003
     A004
@SUM (@DESCENDANTS ("Profit")) works fine, but we also need to sum the accounts for the parent member of the current business that is evaluated, I have tried @SUM (@DESCENDANTS ("Profit")->@PARENT ("Business")) but this does not work.
This however works...
@SUM(
@PARENTVAL("Business","A001"),
@PARENTVAL("Business","A002"),
@PARENTVAL("Business","A003"),
@PARENTVAL("Business","A004"))
Is there a dynamic method to add the parent values together?
Cheers,

How do I preview objects that are outside of artboard.

Hello,
When I placed an illustrator file in Indesign, I would select command+D > select "Show Import Options" and we have a preview of the image. On some occasions, the preview will include all extraneous objects that are outside of the artboard and other times, it will display only the image within the artboard or bounding box. (Please see attached samples)
Does anyone know the reason behind this?
Thanks,
Sutagami

The only way I can reproduce what you are experiencing is if I save out as an .eps and am not mindful of the Artboard check box on the save dialog. If you deselect this check box you will get all of the file content, if you select this check box you will only get the designated Artboard bounding area. But you never said what file format your are saving or what version of Illustrator you are using. I have to assume you are in CS4.
