How to generate formated (defined position) text and image using pl/sql and

Hello,
I need to use pl/sql to create a dynamic html page (or image , if possible) with defined positions for text and bar code. It is necessary because the page will be printed and it should be able to be read by one other process , OCR, that needs to have all the data in defined positions.
Any suggestion are welcome.
Thanks in advance,
Emilio

I don't think it's that easy. Notice that if you put the insert into an actual pl/sql block, you don't get the correct column pointer anymore.
BEGIN insert into bob(col1, col2) values (123.12, 12345.12); END;
ERROR at line 1:
ORA-01438: value larger than specified precision allows for this column
ORA-06512: at line 1

Is it possible to apply conditional formatting to a cell (or range) based upon a LOOKUP query to cell values in another sheet.? I want to alter the formatting (i.e., text and/or cell background color), but not cell content.

Is it possible to apply conditional formatting to a cell (or range) based upon a LOOKUP query to cell values in another sheet.?
I want to alter the formatting (i.e., text and/or cell background color), but not the content, of the target cell(s).

Hi Tom,
Your LOOKUP formula will return a value that it finds in the "other" table. That value can be used in conditional highlighting rules. (Numbers 3 calls it conditional highlighting, not conditional formatting. Just to keep us awake, I guess, but it works the same).
Please explain what you are trying to do.

Ian.

How do I send a group text and not have everyone else get the responses

How do I send a group text and not have everyone else get the responses? Thx

Whether or not everyone gets the response depends solely on the person responding. i.e. you send a group text and i am one of the reciepients. From here i have two options, reply to the group text (everyone gets my reply) or i could text just you on the side (by opeining a new window in messages with just you as the reciepient) and replying to just you. Theres nothing you can do, its up to the person replying whether or not they reply to the entire group or just you seperately.

How to generate payment advice in F110 and send it to Vendors Via Email

Dear SAP Experts
Could anybody tell me how to generate payment advice in F110 and send it to Vendors Via Email?
It would be much appreciated if someone can provide the configuration procedure, thanks so much in advance.
Cheers & Best Regards
Ray

Hi Sama,
Thanks for your post, here I just share some of my idea.
The following step is to configure the payment advice.
In OBVU (payment methods in cpy code) I entered my payment advice form
In OBVU (payment methods in cpy code) set "Always pyt advice"
In OBVCU (payment method by country) leave the payment medium program (RFFOD__T)
For the email sending program, should develp some customized program to realize that, Thanks.
Cheers & Best Regards

How to send message to a multi-consumer queue using pl/sql

How to send message to a multi-consumer queue using pl/sql ? Thanks.
I tried following, but got an message: no receipient specified.
DBMS_AQ.ENQUEUE(
queue_name => 'aqadm.multi_queue',
enqueue_options => queue_options,
message_properties => message_properties,
payload => my_message,
msgid => message_id);
COMMIT;
END;
/

Here's two way to enqueue/publish new message into multi-consumer queue.
(1) Use explicitly declared recipient list
- Specify "Recipients" by setting recipient_list to messge_properties, before ENQUEUE().
DECLARE
recipients DBMS_AQ.aq$_recipient_list_t;
BEGIN
recipients(1) := sys.aq$_agent('RECIPIENTNAME',NULL,NULL);
message_properties.recipient_list := recipients ;
(2)Or, declare subscriber list permanently. Then you need not to specify recipient list each time you call ENQUEUE().
begin
dbms_aqadm.add_subscriber(
queue_name=>'YOURQUEUE',
subscriber=> sys.aq$_agent('RECIPIENTNAME', null, null)
end;
You can add 1024 local subscriber include maximum 32 remote-queue-consumer to one queue.

How can i copy line with text and image to ms word

When I insert an image in textflow using InlineGraphicElement it works, but when I copy the line with the image to MS Word it copies only the text (not the image).
How can i copy the image to MS Word?

If you want copy formatted text and image to MS Word, you need to give MS Word rtf markup, because Word can recognize rtf markup but not TLF markup.
So you need to create a custom clipboard to paste a rtf markup. It's a large feature for you, because you need a tlf-rtf converter in your custom clipboard.
TLF Custom Clipboard Example:
package
 import flash.display.Sprite;
 import flash.desktop.ClipboardFormats;
 import flashx.textLayout.container.ContainerController;
 import flashx.textLayout.conversion.ITextImporter;
 import flashx.textLayout.conversion.TextConverter;
 import flashx.textLayout.edit.EditManager;
 import flashx.textLayout.elements.*;
 import flashx.undo.UndoManager;
 // Example code to install a custom clipboard format. This one installs at the front of the list (overriding all later formats)
 // and adds a handler for plain text that strips out all consonants (everything except aeiou).
 public class CustomClipboardFormat extends Sprite
 public function CustomClipboardFormat()
 var textFlow:TextFlow = setup();
 TextConverter.addFormatAt(0, "vowelsOnly_extraList", VowelsOnlyImporter, AdditionalListExporter, "air:text" /* it's a converter for cliboard */);
 private const markup:String = '<TextFlow whiteSpaceCollapse="preserve" version="2.0.0" xmlns="http://ns.adobe.com/textLayout/2008">Anything you paste will have all consonants removed.</TextFlow>';
 private function setup():TextFlow
 var importer:ITextImporter = TextConverter.getImporter(TextConverter.TEXT_LAYOUT_FORMAT);
 var textFlow:TextFlow = importer.importToFlow(markup);
 textFlow.flowComposer.addController(new ContainerController(this,500,200));
 textFlow.interactionManager = new EditManager(new UndoManager());
 textFlow.flowComposer.updateAllControllers();
 return textFlow;

How to control formatting of include text in smartform

Hello Everyone - I have converted sales order acknowledgements from sapscript to smartform. I need to print material sales text at line level. Include text method is being used, it works in most cases. However, in some cases the Std Paragraph format coded in the include text, is being ignored and the text prints as per default standard paragraph format defined in the smart style.
The only difference I could find in the text set up, using read_text function, is that the format character for the first line. The desired formatting is achieved when the formatting character is '*', otherwise the format defaults to the standard default paragraph defined in the smart style.
Could anyone suggest if there is a way to keep the paragraph formatting consistent and always use the formatting defined in the include text.
Thanks in advance,
Anil

I have resolved this issue. The include text node was defined twice for the form and I had only assigned standard and first paragraph to one of them. The alignment error occured when the second include text was executed. Modified the second node to be same as the first and all worked as expected.

Since it is showing up in Disk Utility, try selecting it, then clicking the Partition button, choosing GUID partition table as an Option and Mac OS Extended (Journaled) as the format.

how can I save that change in 3D from Adobe to Microsoft.

You haven't said what version of Pages you are referring to.
Hold down the option key when you go to the File menu and Save As… appears.
It was Apple stiff necked response to users complaint about its removal. They couldn't just put it back.
Once you do do this it is pretty much what it was before.

How can I format my primary HD and reinstall Lion?

So my iMac has been running very slowly lately, and I've had some tech issues (see the fruitless help thread at http://hintsforums.macworld.com/showthread.php?p=634569), so I'm tempted to just wipe my hard drive clean and reinstall Lion.
I have a backup HD, so I should have sufficient hardware to do this. I just have a couple questions about the mechanics:
1. How do I format my primary hard drive? I assume this is straightforward.
2. Is it possible to reinstall Lion without an install CD? I downloaded Lion off the App Store, and I'd hate to think that because of that I'm stuck with the installation I have.
Any advice would be appreciated. Thanks!
