Dynamically setting the number of collumns...

Hi,
I have a report that I need to build. In the requirements I need to dynamically set the number of columns based on the parameters given. I have some ideas on how to do this by building the layout to include all the columns. Then show or hide them based on the parameters passed. I was just wondering if anyone has tried to do something like this? If so, were you successful, and what were some of the major stumbling blocks you ran into. Or if you know of any links to documentation that would help would be great.
On a side note, would doing something like this be handled better if done in Discoverer? I have not used Discoverer before, so I'm not sure myself.
Thanks,
Tom

How to set the number of rows per page dynamically

Hello all,
i urgent need the option to set the number of rows per page dynamically.
I've got a parameter.
In dependence of the value of this paramter i want to set the number of rows per page of a repeating frame.
The Reports Builder version i use is 10.1.2.0.2
I defined a report trigger.
My code so far:
function R_G_BEMERKUNGFormatTrigger return boolean is
begin
if :vYN_Display_one_per_page = 'Y' then
--what i've to write right here??
return (TRUE);
else
     return (TRUE);
end if;
return (TRUE);
end;
Can anyone help me please??
Best regards
Florian

Do you just need to change back and forth between 1 and some other number? If so, you can create two identical layouts, one with the "number of rows per page" preperty (on the repeating frame) set to 1 and the other layout set to whatever. You would have to have duplicate layouts for each group you wanted to do this with. Your format trigger on the outermost master group frame where num of rows was 1 would look like:
function M_G_ename_GRPFRFormatTrigger return boolean is
begin
if :vYN_Display_one_per_page = 'Y' then
    return (TRUE);
else
    return (FALSE);
end if;
end;Your format trigger on the outermost master group frame where num of rows was whatever would look like:
function M_G_ename_GRPFR1FormatTrigger return boolean is

How to set the number of sockets for batch processing at runtime?

Hello all,
I need to change the execution model at runtime. I have achieved this by setting the 'ModelPath' property of the sequence file at runtime. When I set the sequence file model as batchmodel, i need to set the number of test sockets also dynamically. How can this be done? Once i set the number of sockets, i would also have to set the UUT serial number for each socket. Please help me out in solving this.
Thanks and Regards
Madhu Srinivasan.

Hi Madhu,
You can do this by inserting a sequence file callback into your main sequence and choose the ModelOptions callback. You can then use the expression step to set the "Parameters.ModelOptions.NumTestSockets" value to whatever you want. If you then use the Test UUTs execution entry point you will be prompted for serial numbers automatically. You could also use this same procedure but alter the ModelOptions callback in the process model directly, either way works just as well but I think that using a sequence file callback gives a bit more flexibility in the system.
Hope this helps,
Nick

Dynamically modifying the number of Form detail rows

Hi,
A challenge for you all!
I am building a product details system in Portal forms.
One of the screens is a Product Ingredients form with Product as the master block and ingredients as the Detail block. There can be between 1 and 20 ingredients in any 1 product and as these all have to sum to a volume percentage of 100% the client would like to see all ingredients for a product on 1 screen and not have to do Next/Previous to see them all.
As you increase detail rows on a master detail form the performance of the form decreases dramatically so I would like to minimise the number of detail rows displayed for each product to maximise performance.
To this end I wish to dynamically modify the number of detail rows displayed to match the number of ingredients on a product as that product is queried.
I can handle figuring out how many rows I want to set the page to but have not been able to figure out how to change the number of detail rows displayed at run time.
Anyone know how (or if!) this is possible ?
All help gratefully recieved
Andy

The rownum pseudo-column hold the number of the row but it doesn't work like you expect. It is assigned before sorting for example and it is not absolute. SQL conceptually deals with sets and sets have no inherent order. See http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html
If you want to have an absolute number in a row you will need to maintain it yourself with PLSQL code.

How to set the number of decimal places.

Just wondering what and where the code would be to set the number of decimal places when calculating an answer.

Depending on exactly what result you want you could alternatively format the result to a set number of decimal places.
This is not so good for financial applications where they want the total of 10 transactions to match the total of each number displayed but can be kind of important for scientific ones.
eg
someNumber.ToString("N3"));
Gives you three decimal places without changing the someNumber.
If this turned out to be wpf then you have stringformat you can use on a binding.
Hope that helps.

How do I set the number of simultaneous downloads? Per server?

iTunes always tries to download 3 podcasts at once, which leads to timeouts on podcast servers that limit the number of connections. That means I'm either missing episodes or else I need to manually babysit iTunes.
Is there a way to set the number of simultaneous downloads? I'm using XP.
Thanks.

You can turn simultaneous downloads off. In the downloads window, at the lower left. Also, while things are downloading, you can pause all but one or two.

How to set the number of seconds (or time) a photo is displayed on a slideshow (ATV2)

Can I set the number of seconds a photo stays on the TV screen when I do a slideshow from my ATV2? Can't seem to find a setting on the Apple TV to do that. For the slideshow on the ATV2 I am choosing an Event from my iPhoto library and then choosing "slideshow" after adjusting the ATV2 settings for music and theme.

You can only set the time of slides with certain types of slideshows (i.e. classic and ken burns)

How to set the number of rows that an awt.Choice can display

Dear Sir,
I want to ask how an awt.Choice can set the number of rows that it can display, like the method setMaximumRowCount in JCombobox. Since I want to set more row can be displayed, but choice no any method can set. And I have tried to add Jcombobox into awt.frame, then, the handling event function cannot receive event for the right-top cornet button(minimize, maximum, close).

How to set the number of records displayed at run time

Is it possible to set the number of records displayed block property at run time? The built-in 'GET_BLOCK_PROPERTY' can retrieve the number of RECORDS_DISPLAYED. But I can't find SET_BLOCK_PROPERTY to set this property. Is there anyway I can set this property programmatically? Thanks for any suggestions!

Bookmark Go to End
goal: How to vary the number of records displayed in a block
programmatically
fact: Oracle Forms Developer
fix:
Block property 'Number of Records Displayed' can not be changed during runtime
using SET_BLOCK_PROPERTY. However, it is still possible programmatically change
the visual appearance of the form so that it creates effect of changing this
property. To achieve such an effect follow these steps:
1. in Forms Builder, in the multirecord block define the new set of items.
The simplest way is to copy/paste the original item and rename created item.
2. set properties of these new items so that they are the same as the properties
of the original items. If these new items were copied from original items
then properties are already the same. Modify following properties
'Database item' on new items to value 'No'
'Synchronize with item' to the value of the original item
'Number of Items Displayed' to desired value.
'Visible' to 'No'
In other words, these new items are mirrors of original items.
3. code event, which is meant to trigger the change in block appearance.
This code should use SET_ITEM_PROPERTY built-in to set properties
like 'VISIBLE', 'ENABLED', 'NAVIGABLE', 'UPDATE_ALLOWED' and others
to desired value for items which are about to be displayed, then
move cursor to one of these just displayed items with GO_ITEM built-in
and then hide the previously displayed items.
Example:
Assume that the block is built on SCOTT.DEPT schema. Following will
change the set of displayed items
set_item_property('dept.mdeptno',visible,property_true);
set_item_property('dept.mdname',visible,property_true);
set_item_property('dept.mloc',visible,property_true);
set_item_property('dept.mdeptno',enabled,property_true);
set_item_property('dept.mdname',enabled,property_true);
set_item_property('dept.mloc',enabled,property_true);
set_item_property('dept.mdeptno',update_allowed,property_true);
set_item_property('dept.mdname',update_allowed,property_true);
set_item_property('dept.mloc',update_allowed,property_true);
set_item_property('dept.mdeptno',navigable,property_true);
set_item_property('dept.mdname',navigable,property_true);
set_item_property('dept.mloc',navigable,property_true);
go_item('dept.mdeptno');
set_item_property('dept.deptno',visible,property_false);
set_item_property('dept.dname',visible,property_false);
set_item_property('dept.loc',visible,property_false);

How to set the number of seconds a servlet is allowed to run

I use JSP to generate a report, but it will take about 10 minutes to search.
IE Client screen displays an error message what is "Cannot find out your page" after 8 minutes. How to set the number of seconds a servlet is allowed to run.

It's not a matter of how long the servlet is running... it's the browser timing out because the servlet hasn't responded to its request.
You have several options:
1) "Browser Pinging"
Your servlet sends some small data which can be either seen or unseen (html comments, hidden chars, etc) by the user at short intervals while your report is running. When the report is finished, the browser will not have timed out because it has been "snacking" on those small bits of data which tell the browser its original request was both heard and being handled. I don't think there is any timeout in IE as long as it receives data continually (or at least before its own timeout mark over and over again...)
2) Multithreaded processing
This would probably be a better approach. Have the report run in a separate thread running on the server. You'd want to store a reference to this executing report in the user's session. Instead of making the browser wait for the report to be finished, have the servlet check the user's session to see if a report exists and is running. If one does not exist, create one and start its execution. If one does exist, and is still running, print a "please wait" type of message OR an animation, etc... along with some javascript which will reload the page every few seconds. If the page reloads and the servlet sees that the report is finished, it can then display it to the user.
Hope this helps,
-Scott

How to dynamically set the name of the generated PDF file sent by email

Hello,
I am using Reports 10g and I managed to send PDF reports by email, specifying the recipient, subject, format etc, using the reports servlet URL.
But there is one thing that I cannot find a way to do: I want to dynamically set the name of the attached file. It defaults to the name of the RDF file (eg monthly_sales.pdf). I would like it to be something more meaningful (eg monthly_sales_072010.pdf, where 072010 is the month and year passed by parameters).
Is it possible to do it?
Thanks
Luis

Use System.load(...) instead of System.loadLibrary(...).

XSL-FO Report Query / Named Layout - Dynamically set the output filename

Does anyone know if it is possible to dynamically set the name of the PDF file which is created via FOP?
Thanks
Paul

John
Thanks for the quick reply, apologies, I should have been more explicit.
I am calling apache FOP via a report query and a named column layout using xsl-fo to format the PDF report.
The call is done via a javascript function which determines which report to print and then submits the approproate REQUEST. The request is picked up by conditional branches and calls the PRINT_REPORT
The PRINT_REPORT names the PDF file as same as the report query name.
BTW the long term goal is to store the resultant output as a blob back in the database but I can put that off to phase II of the project as I'm not sure that this is possible. Would be nice though!
Thanks
Paul

How do you dynamically set the flat file name

Within my process flow I call a mapping. Within this mapping I have a flat file operator (which creates and writes to a .csv file). All working great.
From this process flow I want to be able to pass a parameter to the mapping (which I can do), and use the value of this parameter as the file name of the .csv file. But I can’t seem to be able to dynamically set the ‘Default physical file name’ to this parameter value within the mapping.
Does anyone have any ideas?
Thanks
Ansel

How do you set the number of visible items in the popup box of a JComboBox?

Hi,
Do you know how to set the number of items that shall be visible in the popup box of a JComboBox?
I have produced an implementation of an autocomplete JComboBox such that following each character typed in the text field, the popup box is repopulated with items. Normally 8 items are visible when showing the popup box. Sometimes even though the list of items is > 8 the popup box shrinks in height so that 8 items are not visible.
Thanks,
Simon

Below is my JComboBox autocomplete implementation.
The problem seems to occur when the list of items is reduced in number, the button selected and then the list size increased, the popup box does not automatically increase in size. I have tried setMaximumRowCount � but does not resolve the problem.
To see how it works:
1)     click in text field.
2)     Type 1 � the full list of items are shown.
3)     Type 0 � the list has been narrowed down � the popup box is greyed out for remaining items.
4)     Type Backspace � the full list of items is redisplayed.
5)     Type 0 � to narrow down the list.
6)     Select button � the popup box is invisible.
7)     Select button � the popup box is displayed with 2 items.
8)     Select Backspace � here is the problem � the combo box list contains all items but the popup box has been shrunk so that only 2 are visible.
9)     Select button � popup box is invisible.
10)     Select button � popup box is as expected.

How do you set the number of rows in a spreadsheet, so that even when you drag data in, in writes over those rows instead of adding a new row?

How do you set the number of rows you want in a spreadsheet, so that even when you drag data in, in writes over those rows instead of adding a new row?

After the discovery reported above, I filed this report :
Bug ID# 10073038
Summary:
When Numbers is used on a system with decimal comma a csv file may be good AND wrong
Steps to Reproduce:
With Numbers v2, you introduced an interesting enhancement.
In system using the comma as decimal separator, Numbers requires csv files using the semi-colon as values delimiter.
In fact it’s true if we OPEN the document dragging its icon on Numbers one or thru the open dialog.
This said.
(1) Drag and drop a csv built with the 'semi-colon' standard on a table or on a sheet
(2) Drag and drop a csv built with the 'comma' standard on a table or on a sheet
Expected Results:
Every normally constituted user assume that in
case (1) he will get a perfectly built table
case (2) he will get every cells of a row in a single cell
Actual Results:
In fact you forgot the drag and drop way of use and in
case (1) every values separated by semi-colon are inserted in a single cell
case (2) values separated by comma are correctly spread in a table
isn’t it ridiculous ?
Regression:
Except looking in QuickView to see which is exactly the structure of the file to decide the way we will insert it in a Numbers document, we may use an applescript fair enough to replace the semi-colons by TAB characters
or
to replace the commas by TABs and the decimal periods by commas
Notes:
While I am on this subject, I wish to make two proposals:
(1) It would be fine to format the date according to the ISO format year-mm-dd when you export a Numbers doc to csv.
Doing that, dates would be imported correctly in every countries.
At this time, on an English system, you export as mm/dd/year.
If the doc is open on a system using the format dd/mm/year, the results will be odd.
On a system using the format dd/mm/year, you export this way and so, if the doc is open on a system using the format mm/dd/year the results are odd too.
As every localized versions accept the ISO format (at least on entry), using it in the export scheme would give a correct behavior everywhere.
(2) It would be fine to add the format Tab Separated Values in the Export pane.
TSV + ISO date format would give documents opening flawlessly everywhere.
