How to handle substring in page

I'm displaying the value of a column from a table in two
pages - a preview page and a detail page. This column in the db
contains text from an article that includes html tags for
formatting.
On the preview page, I'm displaying the first 500 characters
in this field. (I want to show the first few sentences of the
article) On the detail page, I display all the characters in that
field - the whole article. I ran into a problem today where the
500th character is part of a closing html tag. By displaying less
than the whole tag, the tag is left open on my page and causes
portions of what follows on the page to break.
Any suggestions for better ways to handle this?

Most of the CMS/Blog systems I have come across have 2
fields, one for
the summary, and one for the main content. The Summary is
limited to 500
characters. You then just display the summary on the preview
page, and
then both the summary and the main content on the detail
page.

SSRS: How to handle Landscape PDF page

I’m using SSRS to author PDF documents of size 8.5 * 11. I use the article
here to achieve this. But I don’t know how to handle the situation when one of the PDF page ( not the whole PDF file) is in landscape mode. Here are the steps I’m following
1>
Convert each PDF page into .png. each Size 8.5 * 11in
2>
Create report of size 8.5 * 11
3>
Drag & drop rectangle onto report body. Each rectangle of size 8.5 * 11in. represents one PDF page
4>
Set background image of rectangle to PNG created earlier.
Issue here is, if one the page in PDF is in landscape mode. When I create png for this page I have to rotate the image so that I can author it during design time. This image becomes 11 * 8.5 instead of 8.5 * 11.
If I leave the report size 8.5 * 11 then output PDF creates extra pages.
If set report size 11 * 11 then out PDF is also 11 * 11 ( which we don’t want)
Question:
Is there any way to rotate that particular rectangle (PDF page) clockwise during PDF export. Note that all other pages will be in portrait mode except the one which I want rotate.
Any help, hint will be appreciated

Thanks Katherine
Unfortunately i
cannot use that solution. I'm planning to use SSRS to author PDF document. (as described in this
article here).
So the rectangle will have background set to an image. and then there will be controls (textbox, tables etc) on the top of rectangle image. So setting the rectangle's visibility will not solve my issue.
i think solution would be to author each Landscape page as separate report. and then export them as separate PDF. and merge them using third party APIs
Unless anyone has other solution

How to handle no_data_found in Page/Regions/Body/Report

Hi,
I am new to APEX. I have a report in a the Region area of a Page. The Region Source allows me to enter only SELECT statement, no BEGIN/EXCEPTION/END are allowed. How can I handle a no_data_found exception in a report?
Many thanks.

Thanks for the solution. I tried it, and got with an error:ORA-06550: line 19, column 5: PLS-00372: In a procedure, RETURN statement cannot contain an expression ORA-06550: line 19, column 5: PL/SQL: Statement ignored ORA-06550: line 21, column 5: PLS-00372: In a procedure, RETURN statement cannot contain an expression ORA-06550: line 21, column 5: PL/SQL: Statement ignored
It looks like I am missing something.>
Post your code here in {code} tags.
My guess is you are not escaping single quotes or are not concatenating your Page Item
It should be something like ...
s1 vahracr2(4000) := 'select ..., ''A'' ,... from... where PID = '|| DBMS_ASSERT.ENQUOTE_LITERAL(:P1_CMDCODE);Note the quoting around A to escape the apostrophe and the use of concat.

Standard component's overview page have many components how they handling

Hi All,
As we seen Standard component's overview page have many components as assignment blocks,
how the over view page handling all this, and how these components are interacting with each?
waht is functionality behid it & how they handling this programatically?
Regards,
VJMHYD

Hi VJMHYD
Take BP_HEAD as an example and its overview page view.
BP head overview page will display view with in the same component and views from other component (say BP_ROLE).
1) for the BP_ROLE first interface component has to be defined
2) the interface component defined for BP_ROLE will be used as Component usage in BP_HEAD component (pls check the runtime repository)
3) Create a view of type overview page and assign views to overview page.
4) this overview page will be assigned to window.
Components will interact through component interface and component usage
For more infomation pls check the runtime repository or (generated repository.xml file , don't make any changes to reposito

How to open a JSP page from a form ??? plz help

hi ..
i want to know how to open a jsp page from a oracle apps form using a button .
the requirement is that whenever we click on the button created on the form, it opens a jsp page.
plz help me ..its urgent !! :-(

In portlet project, to navigate between pages, you should not use the URL property to link to a page. Instead, portlets use navigation via action handling. You use the Page Navigation editor to set up links to pages; that is, the navigation editor sets the action property.
Here is an example to hyperlink ans button to open a new page:
# From within the IDE, create a new portlet project. This action creates the project and one page, PortletPage1.jsp.
# Create a second portlet page, called PortletPage2.jsp, for the project.
# Drop a Hyperlink component onto the first portlet page, PortletPage1. (You can drop the Hyperlink on the page in the Design window or on the PortletPage1 node in the Outline window.) Change the Hyperlink's text property to Next Page.
# Drop a Button component (found in the Basic section of the Palette) onto the second portlet page, PortletPage2.
# Open the Page Navigation Editor. It displays the two pages (PortletPage1.jsp and PortletPage2.jsp) of the application.
# Click the PortletPage1.jsp icon in the Navigation window to expand it, and then drag a connector from hyperlink1 to PortletPage2.jsp. Change the name of the connector from case1 to Page2.
# Click the PortletPage2.jsp icon in the Navigation window to expand it, and then drag a connector from button1 to PortletPage1.jsp. Change the name of the connector from case1 to Page1.
# Run and deploy the portlet. The browser displays PortletPage1 and you should see the Next Page hyperlink. When you click the Next Page hyperlink, the Apache Pluto Portal server displays PortletPage2. Click the Page2 button to return to PortletPage1.

How to handle the OK button of the parameters prompt of a crystal report

Hi,
how to handle the OK button of the parameters prompt of a crystal report in vba.NET?
I want to use the parameter prompt from the crystal report itself and I want to know when the report is ready. I need to export programatically by sending email to a list of employees after the parameters has been set. The emails I send depends on the results of the report.
Im using a CrystalReportViewer control in VS2010 and Crystal Report for VS2010 v13.0.1.220.

Right. But the parameter screen is driven by the viewer. Unless you create your own parameter screen and pass the parameters to the report via code.
Another thing I am not sure about:
"Then by code I want to read all the employees id from the report and send email to them with specified pages of the report. (1 page per employee)"
How do you plan on reading the employee ID from the report? I am not aware of any API that will read a value in a report so that you can then decide what page to send to whom.
I think you're approaching this kinda backwards. A question to ask is; can you do what you are trying to do in code in the CR designer? If not, using APIs will not work either. I suspect your approach should be a report that uses an employee filter. Run the report for employee x, get the report populated with the data for that employee and email it. Repeat for employee x1, employee x2, etc.

Suggestions on how to handle "Hacked Skype Account...

I. User Can Still Access Account
Run a full anti-virus scan (and other security scans available in your computer). This may help to detect and remove any elements that the hacker may have used in gaining access to your account.
2. Immediately Change Your Password, preferably with something that is difficult to guess, and not related or totally different from the passwords you previously used.
3. If the hacker also changed your registered email address, changed it back to your own email address. Here is the link on how to change your registered email address;

4. Contact Skype to report the incident. They may be able to provide you with further explanation, clarification and helpful advice. Use the Subject Security & Privacy >> Identity theft / Account takeover.
https://support.skype.com/support_selection
5. You can also contact your bank to inform or alert them of the incident if there is a payment method registered in your Skype account.   They may also be able to provide you with additional suggestions, advice, or options.
II. User Can Not Access Account (Password Has Been Changed) – Registered Email Address Not Changed.
Run a full anti-virus scan (and other security scans available in your computer). This may help to detect and remove any elements that the hacker may have used in gaining access to your account.

Skype is useless for this.
They will claim that you the user are responsible, and that they don't need to do anyhing.
So....
Do not allow Skype to autorefill your account when it runs low on balance, and do not store a creditcard, or other payment info with them.
Each user is liable for whatever the hackers can steal.
As this is from recent personal experience, I recommend you to never keep payment information on file with Skype.

How can I have a Pages document that is shared with me under my Pages section and not open it with the link?

How can I have a Pages document that is shared with me under my Pages section and not open it with the link?

Try this.
Open the document and select and copy a few pages, say ten pages.
Open a new blank document and paste the pages you copied into that.
Save it with a new name.
Work on those new pages to see if the problem has disappeared.
If this helps, continue breaking up the large file in to smaller chunks and working on them
You can of course later reverse the process and merge the files into one new one.
This suggestion is based on my experiences with large Word files. Breaking it up in to smaller chunks does two things. First, if there is any corruption in the old file, the new copies might escape that. Second, the Mac is faster handling the smaller chunks.

How to handle the quotes('') in the procedure?

Hi all,
I have been struggling with an issue in the procedure. Let us go to the functionality of the preocedure.

How to redirect to other page in a dialogListener?

Hi All,
I am using JDeveloper 11g with ADF BC.
How to redirect to another page from a dialogListener of <af:dialog>?
I have a page with a [Delete] button on it. When user click on the delete button, a confirmation dialog will appear to ask "Are you sure? [Yes/No]". If user answer [Yes], I will delete the current record, and go to another page. I can call a Operation Binding in the dialogListener, but I don't know how to go to another page.
public void handleDeleteDialog(DialogEvent dialogEvent) {
OperationBinding operationBinding = bindings.getOperationBinding("Delete");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
// redirect to another page?

Hi Samson,
Check following link for your query:-
Re: page has to navigate to the next page when clicking button in the popup
You can also make usae of Navigation Handler to invoke the navigation action in your task flow as
FacesContext facesCtx = FacesContext.getCurrentInstance();
NavigationHandler nh = facesCtx.getApplication().getNavigationHandler();
nh.handleNavigation(facesCtx, "", "ActionNameInTaskFlow");

PDF Form to XML. How to handle invoice detail lines

I am using LC Designer 7.x on a PDF form that has a submit button that loads a ColdFusion MX7 page that will save the XML in a MS SQL 2005 XML field.
My source of confusion is how to handle the invoice detail lines on the PDF invoice form.
The XML that I want is
    5 All Season Tires
    400.02
    A car with 5 wheels
    20400.00
My question is how do I setup the form fields to do this.
What I did prior to XML was have fields whose name included the line number and store them as FDF.
eg
    description01 amount01 description02 amount02
But that will not work, or I dont know how to translate that to the desired XML.
Any thoughts you might have would be appreciated.
Thanks
Archie Campbell

Archie,
You want to create a subform called "invoiceLine" which you've set to repeat for each data item using the Binding tab of the Object palette. This subform must be contained within another (e.g. "invoiceLines") whose content is set to be "Flowed" on the Subform tab of the Object palette. So your object hierarchy looks like:
invoiceLines = subform with flowed content
    invoiceLine = subform repeated for each data item
      description
      amount

How to handle an invisible character in a string?

Hi,
I have an interesting situation-
select bac_person_id, length(bac_person_id) from bkmap_personid_stg where BAC_PERSON_ID like '%27136317%'
The result is -
BAC_PERSON_ID|LENGTH(BAC_PERSON_ID)
27136317| 9
I don't know what is the invisible character here?
It is certainly not a blank character as trim is not working -
select * from bkmap_personid_stg where trim(BAC_PERSON_ID) = '27136317'
no records!!
But substr does give me the resullt -
select * from bkmap_personid_stg where substr(BAC_PERSON_ID,1,8) = '27136317'
How can I know which is the last character? and How to handle it?

girija_pathak wrote:
How can I know which is the last character? and How to handle it?You use the DUMP() function in SQL in order to see the actual content of the column.
E.g.
select DUMP(bac_person_id) from bkmap_personid_stg where bac_person_id like '%27136317%'
The decimal character values will be displayed - enabling you to see where and what control characters characters exist in the string value for that column.
