Hello.. I have one problem. I used automator to automaticly sync my photos to iphoto. Now I don't want it any more. How can I disable it?
If you have iPhoto v9.6.1 then just launch it. Done.
IF you don't, download it:
Go to the App Store and check out the Purchases List. If iPhoto is there then it will be v9.6.1
If it is there, then drag your existing iPhoto app (not the library, just the app) to the trash
Install the App from the App Store.
Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.
http://support.apple.com/kb/HT4928
One question often asked: Will I lose my Photos if I reinstall?
iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always. -

Hey Shamannnig!
Here is an article that can explain a little more about this situation:
Why can’t I select None when I edit my payment information?

Hello,
i have a selection problem with JTable. I want to allow only single cell selection and additionally limit the selection to the first column.
I preffered the style from MS Outlook Express where you can select the email accounts to edit.
It is a table like this:
Account name | Type | ...
--------------|---------|---------------------
Hotmail | POP3 |
GMX | IMAP |The selection should be only avaibable at 'Hotmail' or 'GMX' - not at 'POP3', 'IMAP' or as complete row selection.
Please help me!
Thanks.

How can I make a non editable JTable? And...
How can I set the columns in my JTable to not be reorganizable?
I'd like someone to help me if posible.
Thanks.
Y si me lee alguien que sepa espa�ol, mi problema es:
En mi aplicaci�n uso una JTable dentro de un ScrollPane y luego visualizo la JTable que contiene unos datos que he leido de una base de datos. �Com� puedo hacer para impedir que las celdas de la tabla se puedan editar? Y... �C�mo impido que las columnas de la tabla se puedan reorganizar usando el rat�n?
Muchas gracias a todos.
Saludos.Hi,
you should not be afraid of this column repositioning feature - the columns in your table model (your data) do not change this way - they stay on their postions, but you will have to use the getValueAt(...) method of the table model with your model indices, not that one of the JTable class, which uses column model indices.
Say, if you only want a JTable to be not editable and you have used the constructor
JTable jt = new JTable(myDataArray,myColumnNames);
to create it from an Object[][] and a String[] - you can simply use an inner class to achieve this:
DefaultTableModel m = new DefaultTableModel(myDataArray,myColumnNames) {
public boolean isCellEditable(int row,int column) { return false; }};
JTable jt = new JTable(m);
to retrieve cell data from this model use:
Object obj = m.getValueAt(row,column);
See the documentation of DefaultTableModel for more information

Hi,
I have encountered a problem with JTable, i am trying to display some 15 columns and their values , one of the columns value is null, then the JTable is not displaying its value from this column(which is with null value) onwards.
Can anybody assiss me in this matter.
Regards
khiz_engI don't know If I can fix your problem, but
I know just that it works on my PC.... It's very very
slow... I don't know how to insert PageSetUp option... I have to study the problem.....
However I don't think it's a hard problem....
I want ask to you if you have found some problems when you are in Editing mode in a cell.....
in the jdk1.2 version I could save while was in editing mode using the editingStopped method.
It permit to update all data .... also the data in the cell I was editing.
in the jdk 1.3 if I use this method It doesn't work properly... It maybe destroy the content object in the Cell..... because I'm able to print all the table except the editing cell (it throw an exception...)
What's changed????
I don't know...
Can u help me? -
Imac - dvi to hdmi. It works great, but I have one problem with blue flicker on my imac
Yesterday I bought a dvi to hdmi connector from Apple store, and successfully connected my iMac (10.6.8) to an LG 50" monitor.
It works great with one problem. My imac flickers blue every 2 secs when TV is on but set to other inputs.
We use the TV for other things (TiVo, DVD) as they are HDMI1, HDMI2 and the iMac is HDMI3.
I tried several things, and each worked with Audio and Video. I currently have it setup as seperate screens instead of duplicating the screens, but each worked fine. And each had the same problem below.
The problem comes if I am on the iMac and then turn on the TV to watch something. As soon as I do, my iMac display starts flickering blue every 2-3 seconds as it is obviously talking to the LG TV. As soon as I set the TV to HDMI3 everything works. If I turn the TV off, everything works.
I don't want to have to connect the cable every time I want I want to project to the TV (although I guess I can live w/ that). Is there a way to have this setup correctly?
thanks for any help in advance.As an update, after 2 weeks of tinkering with this setup, the iMac is usually able to settle down after about 20 seconds of flittering. And, if it does happen where the iMac stays blue screen, I can switch the TV to show the HDMI input from the computer, which works, and if I want, switch it back.
So, all in all, it works very well. I just needed some more patience. -
I have one problem with Data Guard. My archive log files are not applied.
I have one problem with Data Guard. My archive log files are not applied. However I have received all archive log files to my physical Standby db
I have created a Physical Standby database on Oracle 10gR2 (Windows XP professional). Primary database is on another computer.
In Enterprise Manager on Primary database it looks ok. I get the following message Data Guard status Normal
But as I wrote above the archive log files are not applied
After I created the Physical Standby database, I have also done:
1. I connected to the Physical Standby database instance.
CONNECT SYS/SYS@luda AS SYSDBA
2. I started the Oracle instance at the Physical Standby database without mounting the database.
STARTUP NOMOUNT PFILE=C:\oracle\product\10.2.0\db_1\database\initluda.ora
3. I mounted the Physical Standby database:
ALTER DATABASE MOUNT STANDBY DATABASE
4. I started redo apply on Physical Standby database
alter database recover managed standby database disconnect from session
5. I switched the log files on Physical Standby database
alter system switch logfile
6. I verified the redo data was received and archived on Physical Standby database

Please help me!!!!Hi,
After several tries my redo logs are applied now. I think in my case it had to do with the tnsnames.ora. At this moment I have both database in both tnsnames.ora files using the SID and not the SERVICE_NAME.
Now I want to use DGMGRL. Adding a configuration and a stand-by database is working fine, but when I try to enable the configuration DGMGRL gives no feedback and it looks like it is hanging. The log, although says that it succeeded.
In another session 'show configuration' results in the following, confirming that the enable succeeded.
DGMGRL> show configuration
Configuration
Name: avhtest
Enabled: YES
Protection Mode: MaxPerformance
Fast-Start Failover: DISABLED
Databases:
avhtest - Primary database
avhtestls53 - Physical standby database
Current status for "avhtest":
Warning: ORA-16610: command 'ENABLE CONFIGURATION' in progress
It there anybody that experienced the same problem and/or knows the solution to this?
With kind regards,
Martin Schaap -

}what wrong with this code..
ThanksIn summary, you have one or more columns for which the data must be wholly visible - correct? If you need all the columns to show the whole of their data, you are goinf to have to expand the table, otherwise you can expand a column with something like
myTable.getColumnModel().getColumn(whichever).setPreferredWidth(whatever); -
Problem about jtable and database
The problem is that when i clicked the button to save the values of textfields and text area, although the table is supposed to show the new list of datas from the db, it adds the new data list to the end of the first list. I have to list one old and one new in jtable.

Question
I have one problem and I think it is a settings issue. When I google the web I get results. Now, I visited some website and then I want to return to my search results and pick another search result. And there is a problem: I don't have any markers (diffrent link colour for visited sites in IE) that would help me to distinguish visited and not visited sites.Why start a new and very similar thread to your other one which you have not responded to (have you read the replies?)
I suggest that no response is made to this duplicate thread. -

That is done by selecting the code and then clicking on the "Code" button above the question input area.
The problem is that the size of the frame is greater than the size of the table so the widths of all the columns get adjusted after you specify the original default size.
Your code should be something like:
typeTable.setPreferredScrollableViewportSize(typeTable.getPreferredSize());
JScrollPane typeTableScrollPane=new JScrollPane(typeTable);
mt.pack();
mt.setVisible(true);Or you might be able to use my [Table Column Adjuster|http://www.camick.com/java/blog.html?name=table-column-adjuster] which will resize the columns automatically.
