How do I enable the update, but not insert
Hello
I have a LOV (sports say) and a checkbox (say flag). The user must select at the time of the creation of record.
for the first time when a user selects a sport in LOV, the check box will be disabled.
the user should not be able to create a record with the same sport, unless the existing record indicator is checked.
To do this, I created a display criteria in the PVO of the same table, linking the LOV and the flag.
created GOES in the EO with parameter flag = 'n'.
then he created a validator for the entity using the method.
inside the method, I ran the query'S and used the following condition.
public boolean validatesport() {}
this.getSportsChoicePVO () .executeQuery ();
Set of lines rs = this. getSportsChoicePVO ();
If (RS. GetRowCount() > 0)
Returns true;
on the other
returns the value false;
}
What happen to a sport, it's... If there is no record with indicator = N, its allowing to insert the record.
but as he tried to update the indicator = Y the number be 1 and its not allowing to update.
If I put the count > 1, its to insert the same record with indicator = N, which should not happen twice.
Please suggest what I can do,
whereas when there is already a record, he should be able to update and no insert with the same choice.
Hi Timo,
Thanks.I was able to reach my need of the following logic in the validator of the method.
When count = 0, this means that the user inserts for the first time.
When count = 1, if the entity is changed, it means that it will update and therefore allowed.
public boolean validatesport() {}
this.getSportsChoicePVO () .executeQuery ();
All lines rs = this.getSportsChoicePVO ();
If ((RS. GetRowCount () == 0) | ((getEntityState () == Entity.STATUS_MODIFIED & rs.getRowCount () == 1))
Returns true;
on the other
Returns false;
}

How to re-enable the updater?
When I bought suite Production CS5 I had an internet connection very poor and unreliable, so I disabled the update as he was demanding always updates. Now I'm back to civilization, but can not find the place where or how reactivate the automatic updates for my Adobe products. Can someone help me?
Thank you.
BTW: I could not connect you to the forums using Firefox!
Since how long have you installed all the stuff Adobe? I ask, because I wondered if maybe Windows 7 system restore facilities can help you.
I wonder if trying to uninstall the software from another account from which you used to install might have gotten you troubles here.
Something to try: temporarily disable UAC Windows (drag his control all the way to bottom and then restart), and then log on to the account that you used to install and try the uninstall it.

How to find a specific voice memo file in the backup from my iPhone to my Mac? I know where to find the backup, but not how to recover specific files. Thank you.
You can't look "inside" a backup. Just use iTunes to sync with your iPhone, then you'll see a separate category for voice memos in the sidebar.

I have windows 7 ultimate works correctly. I want to install windows 7 arc gamer edition. I m using the new copy to install from dvd, he is well until the installation of the updates but the installation finished, it displays error windows could not update the configuration to start the computer. not installing and it rolls supports everything. Please help me solve this problem
original title: windows 7 gamer editionDownload of software on these sites can be very risky, because the origin of the files are usually edited and its quite possible that they could have injected malicious code in it.
Windows 7 Gamer edition is not a developed Microsoft or affiliated with the product, what appears to be a customized image of Windows 7 that authors customized to remove or add Windows components, which can also be very problematic.
You use something that no one can help you consider he has probably been reverse engineered and probably injected by a malicious code like spyware (keyloggers, rootkits, worms, viruses). I suggest you stick to Windows 7 Ultimate, this is the most complete edition of Windows 7, anyone can have.

updates available for various cs5 applications, but the updates will not install
I was warned of the updates are available for photoshop cs5 and other associates cs5 updates, but the updates will not install.
can manually download and install updates and the following text error occurred for all updates.
Also acrobat adobe 9 will not be open to all.
Pls help, thanks
I think you need to update to the latest version adobe application manager and the help > updates
from photoshop cs5 should then work.
Adobe - Adobe Application Manager: for Macintosh: Adobe Application Manager
It is also possible that you may need to change your security settings
in Apple > system preferences > Security & Privacy > General to allow downloaded applications on > Anywhere
before the automatic or manual update downloaded the updates to work.

Incompatibility of fix SQL: installed in the PDB but not in the CDB - how to fix?
I have a 12.1.0.1 database in which I wanted to migrate a number of PDB files in the AL32UTF character set. To do this I created a second database (temporary) with the character OK, unplugged and re plugged each PDB and ran the DMA you to migrate the PDB files - all right.
Then, I dropped the first database and built another one with the correct character set.
When I disconnect and reconnect the PDB from temporary to the new database, I get the PDB next violation:
PDB_ACPT_CLONE SQL patch 19648840 offset: installed in the PDB but not in the CDB.
This patch had been applied to the original and then rolled database before the new and temporary databases have been created.

Any ideas on how to solve this problem?
Looks like the restoration of the original patch in CBD was not perfect.
Option could be applying the fix to the PIC and try to plug in the PDB.
