Line limit for JTextArea - Urgent

Hi All,
I would like to have 80 character limit for each line displayed in JTextArea. The linewrap along with wordwrap have been enabled for JTextArea but that solves a part of the problem. The no. of characters that can be entered per line depends on the width of the component and the font size. For this component there is no upper limit for the total no. charaters that can be entered. Basically, it supports text editing feature(cut, copy, paste). One way it could have been done by fixing the width of component so that it could accomodate only 80 characters, but again the factors like screen resolution, font's advance width keeps changing. I tried with overriding insertString() of PlainDocument class, but didn't know how to wrap the characters after 80 position to next line if text is inserted in the middle of a line. At the same time the whole text needs a reformatiing. Same behavior is desirable while doing cut/paste operations.
A hint or sample code will be highly appreciated as it has been a long time I am looking to solve this problem.
Thanks
Ritwick.

You are correct it is not easy to override the default behaviour of the JTextArea. So my suggestion is to use a monospaced font. The code would then be:
JTextArea.textArea = new JTextArea( "some text", 10, 80 );
textArea.setFont( new Font("monospaced", Font.PLAIN, 12) );
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
JScrollPane scrollPane = new JScrollPane( textArea );
scrollPane.setVerticalScrollBarPolicy( JScrollPane.VERTICAL_SCROLLBAR_ALWAYS );If using a monospaced font is not possible, then please explain why wrapping at exactly 80 characters is so important, maybe there is a different approach to take.

Urgent: Setting character limit for JTextArea

Hi, I am newbie to java swing and I have a question.
I need to set a limit of 2000 characters that can be typed in a text box(JTextArea). How do I do that?
Thanks for the help.

Here is the sample code to do this using KeyListener. This is crude way but is an easy way for newbie's. Using documents is more sophisticated way.
<code>
public class LimitedCharsTest extends JFrame {
private JTextArea limitedCharTextArea = new JTextArea();
public static final int MAX_CHARS = 10;
public LimitedCharsTest() {
JScrollPane scrollPane = new JScrollPane(limitedCharTextArea);
this.getContentPane().add(scrollPane);
this.setSize(200,200);
limitedCharTextArea.addKeyListener(new TextAreaKeyListener());
this.setVisible(true);
public static void main(String[] args) {
LimitedCharsTest limitedCharsTest1 = new LimitedCharsTest();
private class TextAreaKeyListener extends KeyAdapter {
public void keyTyped(KeyEvent ke) {
String taContent = limitedCharTextArea.getText();
if(taContent != null && taContent.length() >= MAX_CHARS)
ke.consume();
</code>

FBL1N - Limit display line itens for some vendors

Hi All,
I have a request from business to limit the access for some vendors in FBL1N.
The idea is to limit the users to do not see the line itens for some vendors.
Is there some standard configuration? Any suggestion?

Ricardo,
My suggestion is to involve a Basis person for this. You need to check the authorization object attached to Vendor line item display transaction FBL1N.
Then explain to the Basis person the conditions in which certain line items should not be displayed. I am sure this exercise would be of help.

Vishal.

Price limit for material -- very urgent requirement

hi gurus,
i m facing a prob., actually we want to assign a certain amount for a material and we ask our users to procure that material from any vendor, But they can not exceed that limit which we had defined while creating the info-record and Purchase order.
how could i do that.
useful answer will be awarded..
please reply soon.. its very very urgent.
Thanks:
piyush singh

hi gurus,
I m telling you my problem in more clear way:
while creating a PO the value get updated from info-record, this value should be under certain limit so that the End-user can not exceed the material price after a certain limit in PO.
if the End-user changes the info-record or creat the info-record with price exceeding that limit ,the syatem will pop-up a message and can't allow the end-user to save, and even if they get it saved.. then the system will not allow end-user to save the PO with that exceeding price.
the scenario is as follows:
we fixed a price limit some-where for material Xand ask our end-user that you can buy the material X
from any of the vendors. they whether then go to creat new info-record or change the existing info-record.
THEN,
the system can only save or change the price in info-record under the defined limit, if exceeding the system will not get saved the info-record.
OR
If he succedeed to save the info-record with the exceeded value, Then this changed price will get pop-up while creating PO , but if the value of the PO foe material X exceed the limit which we had defined for that material X the system can't save the PO.
Where will i set this Limit for Material X.

Why am I getting a "Adobe Creative Cloud Membership has reached its limit for hosted sites" message?

I just tried to push my FIRST "free" Creative Cloud site live and got the message "Your Adobe Creative Cloud Membership has reached its limit for hosted sites. To push this site live you will need to purchase an additional hosting plan." I thought CC membership was supposed to give you 5 free hosted web basics sites?
I am a premium BC partner and so far have my partner site and a paid Webcommerce site . In addition to the site I'm trying to put live I have 2 other trial sites (think they are designated as WebMarketing sites) of which one is expired. So where does the limit come in as this is so far my only WebBasics site?
Please help as I need this live urgently (without additional expense).

Finding the end of a line in a JTextArea and inserting a comma

Hi,
At the moment I am reading in a comma delimited file into a JTextArea.
This part is ok I can see the file in the window correctly.
The problem that I am having now is that I want to add a comma to the end of each line in the JTextArea.
Does anyone know how to do this?
Thank you

Well you have to get the String value of the JTextField.
String text = YourJTextField.getText()
Then you have to make a loop and check each single character if it equals '\n', that means "RETURN" or "NEW LINE".
That is the direction I would go. Inform yourself about String manipulations first, like how to look for character, how to compare them and how to add them.

Tolerance limit for invoice

Hi all,
We have a requirement where we need to put tolerance limit for invoice both at the line item level and header level of the invoice. Also both % and absolute tolerance limits.i.e. if the invoice is 25 EUR or 3% more than the suggested price, it should be blocked. It is true both at line item and header level independently.
I tried in test systems and at line item level, we could achieve it thru configuring PP tolerance key.
Also at the header level, BD helps in achieving the Absolute tolerance.
But how can we configure at header level, % value of tolerance limit?
Appreciate the help.
Thanks,

I don't think there will be separate tolerance limit for header level in invoicing, it will not allow you to post with diff values in item and header.
Just check and let me know, if this wrong.

Help to overcome 32K XML limit for Anychart Map

Hello,
Apex version 4.2.0.00.27
I am creating a heat map using the Anychart maps and have chosen to use the "Use custom XML" option in the Map Attributes to control the map being generated. However, I have hit a 32K limit for 'Custom XML' that is being passed to the Map.
A sample of the XML is:
<?xml version="1.0" encoding="UTF-8"?>
<anychart>
<charts>
<chart plot_type="Map">
<b>&P_MAPXML.</b>
<palettes>
</palettes>
</chart>
</charts>
</anychart>
I am using a procedure to generate the required XML and have created an Application Item (P_MAPXML) to hold the data. When P_MAPXML along with the enclosing XML is less than 32K then map dispalys correctly. If the XML generated is more than 32K then an error occurs as it truncates P_MAPXML and the Custom XML is no longer well formed.
There is a workaound via an old thread AnyChart gantt with custom xml and more then 32k but I was wondering is there a more upto date solution.

Thanks Hiliary,
I soldiered on before I saw your reply.
I basically wanted an example of the minimum necessary to display an Anychart Map via the javascript method as there seemed to be issues with the examples that were on the forums not least assuming that every step was understood.
Anyway below I have put steps together just to display an Anychart Map and then along with your example above or the others from the Forum it can be customized to display dynamic data.
1. Create a new page within Apex
i) Under Application choose Create Page -> Blank Page -> Page Alias - (type: WorldMap) -> Name (type: World Map) -> ->Finish
2) Click Edit Page
3) Right Click on Region , Choose Create -> Click PL/Sql Dynamic Content ->Title (type: World Map) ->
Under Pl/SQL Source cut and paste the following:
<pre>
htp.prn('<textarea cols="500" rows="100" id="rowData" style="display:none">');
htp.prn('<anychart>
<charts>
<chart plot_type="Map">
<chart_settings>
<title enabled="true"><text>World Map</text></title>
<chart_background enabled="false"/>
<data_plot_background enabled="false"/>
</chart_settings>
<data_plot_settings>
<map_series source="world/world.amap">
<projection type="Mercator" centroid_x="10.4515266418457" centroid_y="51.1656913757324"/>
<undefined_map_region>
     <tooltip_settings enabled="true">
               <format>{%REGION_NAME}</format>
          </tooltip_settings>
          <label_settings enabled="true">
               <format>{%REGION_NAME}</format>
          </label_settings>
     </undefined_map_region>
     </map_series>
</data_plot_settings>
<data>
</data>
</chart>
</charts>
</anychart>');
htp.prn('</textarea>');
-- Line below seems to be coming out blank, should be:"
htp.prn('<div id="chartMap"></div>');
htp.prn('<script type="text/javascript" language="javascript" src="/i/flashchart/js/AnyChart.js"></script>
<script type="text/javascript" language="javascript">
AnyChart.swfFile = ''/i/flashchart/swf/AnyChart.swf'';
var chart = new AnyChart();
chart.width = "800";
chart.height = "400";
var data = document.getElementById("rowData").value.toString();
chart.setData(data);
chart.write("chartMap");
// alert(data);
</script>');
</pre>
Click Create Region
4) Run the Page.
If all is well it shoulld display the World Map, just be careful with the div tag line as that will need to added manually.
As said previously, there's lots of help on the forums about creating the dynamic content but this should be a good place to start, having a map that will display using that method.

Getting the visible lines from a JTextArea

I'm using a JTextArea with a fixed size. I've used the setLineWrap(true) and setWrapStyleWord(true) methods on this JTextArea, so when the user types in some text longer than the visible width, it will wrap into the next line. I need to get each visible line from the JTextArea to create a String array of text lines.
I mean visible text lines (lines visibly separated in the JTextArea), not real text lines separated by a line break character as "\n".
How can I do this?

This information is supposed to be contained in the View information of the component. But as far as I can tell it doesn't work for a JTextArea.
So if you can use a JTextPane then check out the "getWrappedLines" method in this posting:
http://forum.java.sun.com/thread.jspa?forumID=57&threadID=608220
Basically, a View exists for each line in the Document and then each line may have multiple views if the line needs to wrap. So the basic code just count the number of views within each line but you can change the code to get each view separately. Once you have each view you can get the start and end of the text from the document that this View represents.
Or if you need to use a JTextArea then you can calculate the starting offset of each each line with respect to the model. You can use the viewToModel(..) method to get the starting offset of each line. We know that each line in a text area is a fixed height, so the starting offset of the first line would be modelToView(0, 0); If the line height is 16, then the starting offset of the second line would be modelToView(0, 16), etc. Once you know the starting offset of each line you can subString out the text for each line.

Maximum no of Line items for sales order,delivery document and billing docu

Dear friends,
How many line items we can enter for the following,
1) a Sales order
2) a Delivery document
3) a Billing Document
Thanks in advance.
Regards,
Shrikant

Hello,
the maximum limit of line items are as follows
order-9999
for delivery and invocie , it is restricted to 999 accouitng line items. since the tranfer to accounting can handle only 999 items , the restriction on delivery and invocie
ex if there are excise postings, for a single line , there might be 5/6 lines genetrated for each line in invocie , therfore as per this the line in invocie get restricted
you have a sap note , which offers suggestions to partially over come this
hope this helps
Thanks

Hi Nilesh,
Before going further, are we using domain admin account to use netdom and adsiedit.msc? Whether it is true or not, please try another admin account to check if the issue persists. Besides, to use netdom, we must run the
netdom command from an elevated command prompt. If the issue persists, please try to join the machine to the domain from the machine itself to see if it can be successful.
