Can you dynamically change an LOV on the parameter form based on other params?

Can you dynamically change an LOV on the parameter form based on other parameters? For example, based on a entered purchase order number, create an LOV of the purchase order lines that belong to the entered PO #.

Hi
Accouding to my knoledge you can't do it.
If you want to build lov for that particular
value, you can do it in Forms.

Null values not displaying in the LOV on the parameter form.

My report works perfect while in Oracle Reports 10g, however when I move it to our menu (Oracle Forms 10g) it does not display the null in the LOV on the parameter form.
This report allows the the user to select by inspector or district or everyone for certain dates.
Ex: I have 4 parameter fields. The user must enter the start & end dates and either the Inspector or the district or leave the inspector or district null to run for everyone.
The district LOV is :
select dnr_section_code, description from dnr_section_code where dnr_section_code in ('29', '38','52')
UNION
select null, 'All' from dual
order by 2 asc ;
The inspector LOV is:
select null , 'All' from dual
UNION
select person_seq, first_name||' '||last_name inspector from vw_eng_inspectors
order by 2 asc
In my Data Model query I use the :
My select
from tables
where clause
+
----by inspector
and (prod_fac_inspections.person_seq_inspector =
nvl(:inspector,prod_fac_inspections.person_seq_inspector))
---by district
and
(d.dnr_section_code = nvl(:district,d.dnr_section_code)
and d.person_seq = prod_fac_inspections.person_seq_inspector)
Again, it works perfect in Reports! It eliminates having 3 reports on the menu. This one report gives the user the option of selecting dynamic parameters.
Also, I got so frustrated, that I went a different route of using a default where.
I am stuck with the error of ORA:00933 SQL command not ended properly
1=1
I set the initial value to 1=1 and it does not like it.
I am stuck!

Hi Krishna,
I'm not sure I understand the probelm.
A progress bar control only displays numeric values. When do you mean by "unassigned values"? What would you expect to be presented?

How Can you dynamically change a canvas frame title?

I am looking for a way to dynamically change the title of a frame on a canvas.

Jim,
frames on a canvas are graphic objects that cannot be controlled using properties. To obtain dynamic frame labels, all you can do is to have a Display Item instead of the frame label.

Is there anyone there? I hope there is someone who can you understand this problem and have the common sense to respond?
I open gmail. I want to save an email to one of my folders.
I position my cursor over the appropriate Folder icon or by choice, to the Trash.
The friendly finger pointing cursor icon changes to an arrow icon.
The hand icon allows me flawless access to opening and/or moving emails.
The arrow, however does not open the link.
On the Google menu bar the cursor hand with finger opens the links to Everett (my name), Search, Images, Maps and Play.
When I attempt to open the remaining links in the menu bar (YouTube, News, Gmail, Drive, Calendar and More) the arrow icon replaces the hand. The arrow icon does not work. It will not activate these links. Nor does it open email messages in the Inbox.
Usually I reset, even reboot Safire and sometimes the problem goes away, then reappears.
Can you imagine if this condition should it happen to a tech savvy Google Support person? Perhaps one can share and make my problem go away.
I am considering dropping Google as my mail source. Unfortunate!

Can you dynamically resize a graphic

In AW 7, can you dynamically resize a graphic (jpg, or

Not as such. You can:
- have multiple copies of the same image and flip between
them (there's
a Show Me on it)
- use Flash
- use alPicView

"You don't, they only appear in open file dialogs and in tool panels like in iMovie, iPhoto.
To view your media, you open the app that you use to manage that type of media." this on the other hand was zero help
What you did doesn't show the Media Browser. It just shows the folders where your media is stored. You may be correct that was all that cobacc wanted.
The Media Browser shows the actual media in thumbnails so that you can preview the media.
However, neither requires any Sharing services to be enabled.

Can you locate your iTouch 5 with the serial number?

Can you locate your iTouch by just the serial number?

No. It will only help identify your iPod if it is recovered.
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up.
- You can also wipe/erase the iPod and have the iPod play a sound via iCloud.
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it unless you had iOS 7 on the device. With iOS 7, one has to enter the Apple ID and password to restore the device.
- Apple will do nothing without a court order
Reporting a lost or stolen Apple product

Can you have two itunes accounts on the same computer?

Can you have two itunes accounts on the same computer and if so how do you access them without syncing each others music?

Yes. Use separate iTunes libraries(launch iTunes with the Shift(Windows) or Option(Mac OS X) key held down as needed), or different user accounts on the computer.

Can you have 2 itunes accounts on the same computer?

can you have 2 itunes account on the same computer?

Yes, go to your Windows Control Panel and create another user,log into it, run iTunes and it's ready to rock and roll.
Transfer your content over via USB Key, Dropbox or external drive.
Heck the best thing would be to File > Backup library to disk with a bunch of DVD-R's, therefore you get a backup in the process!
Good Luck
