Limitation in amount of characters in lov ?

Hi.
Ich habe an updateable report for multirow updates, where i added a "add one row to report" button, to add new rows.
When adding a row a lov is filled by a query to show me values to choose from.
Now i got an error "numeric or value error buffer too small", when executing the lov query.
We found out that the error occurs, when i have lots of characters in my query.
When query returns around 5000 chars, it works, when ist return 16600 chars, filling the lov in my report column fails.
Question : Is the any character limitation in the case (updateable report, filling report column that has type "lov filled by query" with lots of data ) ?
If yes, where is the limit ?
btw. I am using Apex 3.2

Are you using a Select List to display this LOV? There IS a limitation of Select Lists (but I am not sure what that limit exactly is).
Try changing the field to a Popup LOV instead.

Limiting amount of characters in the announcement board app/add-on

Hello,
I am in the process of migrating a company's digital manual into their SharePoint 2013 enviroment.
The whole process is going without any major hiccups but one of the managers wondered if the preview message, as it appears on the frontpage/announcement board, could be limited to a certain amount of characters (kinda like the characters limit in Twitter).
I do have access to SharePoint Designer 2013 if a character limit can be implemented there.
Thanks in advance!

Thanks everyone.
This is what worked for me:
In my source code:
//********Class to limit the number of characters a user can enter into a field.*********
public class LimitedPlainDocument extends javax.swing.text.PlainDocument {
     private int maxLen = -1;
     /** Creates a new instance of LimitedPlainDocument */
     public LimitedPlainDocument() {
     public LimitedPlainDocument(int maxLen) {
          this.maxLen = maxLen;
     public void insertString(int param, String str, javax.swing.text.AttributeSet attributeSet) throws javax.swing.text.BadLocationException {
          if (str != null && maxLen > 0 && this.getLength() + str.length() > maxLen) {
               java.awt.Toolkit.getDefaultToolkit().beep();
               return;
          super.insertString(param, str, attributeSet);
//In my JTextField custom code properties.
//myTextField.setDocument(new LimitedPlainDocument(25));
Still sounds crappy: what if the user tries to paste a long string? I would rather get a prefix of the string than hear a beep.

Limit the amount of characters of a text field based on first digit

Hello and thanks in advance for your help!
I would like to limit the amount of characters of the text field based on the first digit of the number (the text field is only limited to a number format...no decimals, no commas).
For example, if the number begins with a 3, I would like to limit the text field to allow only ten characters. I have three scenarios but if I could get started with some code and what is the best place to add it (keystroke or validation?) I can take it from there. Thanks again for your help!!

I've written this code for you that does that. Use it as the field's custom Keystroke code:
// Validate that only digits are entered
if (event.change) {
    event.rc = /^\d+$/.test(event.change);
// Validate string length if it starts with 3
if (/^3/.test(AFMergeChange(event))) {
    event.rc = AFMergeChange(event).length <= 10;
    if (!event.rc) app.alert("If the number starts with \"3\" it may not be longer than 10 digits.",1); // optional error message
You can duplicate the second part of it for additional conditions, but keep in mind that this code won't even let you remove the first character in the field if the result is an invalid one.
For example, if you enter "234567890123456" then you can't remove the "2" at the start because that would result in an invalid number. You can remove any of the other digits, though, and when it's 10 digits or less then you could remove the starting "2" as well.

PLD - limiting the amount of lines

I have read some of the other threads regarding limiting the amount of lines in a repetitive area. I tried to apply this to my current layout, I am formatting a check, the print is going into the tear away section on the check.
The check is printing 15 lines in this area and I would only like to print 13. I change the format section to 13 lines in repetitive area, with nil effect on the output. Are there any other options?

Hi
What is your set up for print preference for checks for layout ?
Go to administration >> System Initilaisation >>Print Preference
Click on Document tab>>
Find checks for payment >>
What is the maximum lines you have set ?
Hope this helps to troubleshoot your issue
Thank you

Can I open multiple tabs in Firefox when WINDOWS starts up? Command line limits to about 204 characters...

I know how to configure Firefox so that it opens multiple tabs every time you open ''Firefox''. I want it to open multiple tabs when I start ''Windows''. Or in other words, I don't want to connect to multiple web pages every time I open a browser, just the first time I log on for the day.
I tried appending the web sites in the command line of a Firefox shortcut in my Windows Startup folder. The problem is that in this approach, you're limited to as many URL's as you can type in about 204 characters ('C:\Program Files (x86)\Mozilla Firefox\firefox.exe' uses up 52 of the 256 characters available in a shortcut).
Is there a way to open more tabbed web sites than that?
What would be cool is if there was something like a FFstartup.ini file or something, where you could provide a list of websites as long as you want, and it would open them all. So, the command line would look like:
'C:\Program Files (x86)\Mozilla Firefox\firefox.exe' 'C:\Program Files (x86)\Mozilla Firefox\FFstartup.ini'
...and the FFstartup.ini file would look like:
[Startup]
'http://www.yahoo.com'
'http://www.google.com'
'http://www.firefox.com'
etc...
If there's no current way to do this, how would I make this suggestion to be developed?
Thank you!

Use a .bat or .cmd file to start Firefox if you need more space than the target line in a shortcut allows.<br />
Separate the URLs with spaces.

Write-off reason code limited to Amounts

Hi All,
We are on ecc 6.0. I want to know that is it possible to Link Write-off Reason code to amount and Roles.
The scenario is like this. We have Multiple reason code configured in SAP
Bank Charges A write-off reason code:
Cash application specialist can write-off maximum amount of USD 500 for this reason code.
If the amount is more than USD 500 it has to be written off by Role 2 which has the limit of more than USD 500.
Similarly there is other write-off reason code B for which Cash application specialist has a Limit of USD 450000 while Role 2 has a Limit gretaer than USD 450000
Assigning tolerance group to the user would not help as we have different limits for different reason codes.
How can we configure such a scenario.Will we be able to achieve the same by validations/substitutions or we can define an user exit at f-28 level. Any other way to achieve the same.
Thanks in advance
Regard
Nitin

Thank you for your response. I haven't been able to find a way to turn it off yet, but thought someone else might have found a way.

Does use of pipelined/pipe row have a limitation on amount of data returned

We are using Oracle 9i.
We have an existing function that pipes data. Select * from table(cast(schema.my_pkg.get_data() as schema.t_my_data_tab))
Function runs, but only returns around 10,000 records. There are actually about 50,000 records to be returned. I do not believe it is just erroring out one a single and stopping because I sorted my cursor multiple ways to show that in one sort certain records do not show, but when sorted another way they do. It is still possible something is stopping it - I will continue looking. But I would like to know if anyone is aware of any size limitations in the amount of data to be piped? I've looked at the types created & the function and do not see anything that was set for a size. Any ideas?
I apologize I do not know all the correct terms to use. I am taking this over from someone else - hopefully an example of their code will help. Thank you very much.
FUNCTION get_data(p_id NUMBER DEFAULT NULL)
RETURN t_my_data_tab PIPELINED
AS
v_temp VARCHAR2(10);
BEGIN
PIPE ROW
(t_links_contracts_rec
(...data values....)
RETURN;
END;

I'm not sure really, if there was a limitation I believe it would be documented and even would raise an exception. I've only used pipelined table function for smallish sets of data. I can't simulate much as I only have access to 10g and 11g here, so I ran a query with 50,000, but I'm only posting its count for obvious reasons.

Please use

Limiting the amount of space available for time machine

How do I limit the amount of space time machine is allowed to use on my 500gb external hard drive? I need the rest of the space for other stuff. Is there a way to partition the external hard drive or make time machine think there is only a certain amount of space available?

Yes. Open up Disk Utility (located in utilities in your applications folder), and select the drive. Make sure you select the actual Drive (the one with the amount of space listed on the name) on the panel on your left. click the partition tab, and open the drop down menu under "Volume Scheme". choose the number of partitions. I have my external drive at 2 partitions, one for TM and one for general files. move the slider bar that will appear in the panel below to determine the size of the partitions. the size of you TM-dedicated partition should be at least twice the size of the drive you are backing up.
Hope this helps.

Not enough amount of characters in field

In our company we have decided to use the field "Reference" in forms "Outgoing Payments" &
"Incoming Payments" (there are fields OVPM.CounterRef & ORCT.CouterRef) like the field "Customer
Ref. No." in forms "A/R Invoice" & "A/P Invoice".
These fieldsare appropriate for filling number of contract because fields "Reference" and "Customer
Ref. No." both copies into the field "Ref. 2" of "Jurnal entry" when documents are posted.
The fields have characters limit:
"Customer Ref. No." in form "A/P Invoice" - 100 characters
"Customer Ref. No." in form "A/R Invoice" - 100 characters
"Ref. 2" in form "Jurnal entry" - 100 characters
"Reference" in form "Outgoing Payments" - 8 characters!
"Reference" in form "Incoming Payments" - 8 characters!
We would like to have an ability to put into fields "Reference" in forms "Outgoing Payments" &
"Incoming Payments" 100 characters too.

hi,
Work arounds:
Create user defined fields in outgoing/incoming payments and apply formatted search in journal entry Ref2 field to populate data in it.
or
Extract data from user defined fields of outgoing/incoming payments(using query) and update journal entry using DTW.

Limiting the amount of records or pages that gets generated by a report

Post Author: jjurroz
CA Forum: General
Hey guys,I'm using CR 8.5.3I have a quick question that hopefully one of your can help me out with. I have a report that works perfectly and uses a couple different parameters for sorting etc.. I'm using an SQL database and for a particular report, after inputting the correct parameter values the report would generate for example 12,000 records on 2000 pages. What I'm trying to do is create a new parameter that would limit either the amount of pages that gets generated or the amount of records. I think I'd rather limit the amount of records to start off with and I would like it to be from a list of predefined amounts. I.E. "ALL", "First 10", "First 50". Essentially I'm trying to create a report that gives me a subset or sample of the main report so that it could get printed to pdf and sent to customer for review. Any help would be greatly appreciated! Regards,Jose

I can only go to 'TopN/Sort Group Expert' menu option if I add a summary field, otherwise the option is greyed out. If I do add a summary field and go to 'TopN/Sort Group Expert' I have no formula button. I can select TopN from a drop down but then I have to hard code the N value. I'm start to wonder whether its even possible to do it dynamically in CR 8.5. V361:Sorry JJurroz, Here again I have CR XI, so not sure if 8 will do this. Create a number parameter {? Top_N} then go to Group Sort Expert, you should be able to click on the formula button for Top N and put your parameter {? Top_N} in the formula.
That should work.

Limiting JTextField to 4 characters only

I'm making an interface to allow the user to enter 4 groups of 4 digits. This is made up of 4 JTextFields, that when the user has entered the fourth digit in box 1 the interface automatically jumps to box 2 etc, usual stuff. The problem I'm having is with the last box. I've tried to put code into a CaretListener to prevent the user entering more than 4 characters, but if I use a technique like substring to remove the extra character I get a recursion error. I though setColumns was meant to set the limit of characters entered, but I can't get it to work. Does anyone know how I can limit box 4 (txtCode[3]) to 4 characters?
          for (int i = 0; i < txtCode.length; i++)
               txtCode[i] = new JTextField();
               txtCode.setColumns(4);
               final int k = i;
               txtCode[i].addCaretListener(new CaretListener()
               public void caretUpdate(CaretEvent e)
                    if (txtCode[k].getText().length() >= 4)
                         if (k < 3)
                              txtCode[k+1].requestFocus();
                              txtCode[k+1].setCaretPosition(0);

The Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html#filter]Text Component Features shows you how to use a DocumentFilter to accomplish this. Or maybe you should use a JFormattedTextField.

How to have a button accept more than a certain amount of characters.

I am make a game. And I wanted to know how to make people have nicknames. But not 0 characters, I want it to be more that 6 characters. Please help me.

Just like the response you got in the AS3 forum, you can test the length property of the textfield to see how many characters are in it.
