Limit the words usage in the text field

Hi there,
I need some help here. Is there any method that I can use to limit the usage the words in the text field. Its very helpful to me.
Thanks

you can use jformattedfieldtext and use maskformatter to give it a format to limit the number of characters, for example:
MaskFormatter formatter = null;
try {
formatter = new MaskFormatter("####"); //4 numbers only
} catch (java.text.ParseException exc) {
System.err.println("formatter is bad: " + exc.getMessage());
System.exit(-1);
JFormattedTextField jFormattedTextField = new JFormattedTextField(formatter);
good luck

  • Change the font color of a text field in a table by key-combination

    I want to change the font color of a text field in a table (single cell only) on pressing a key combination. Does anybody know how to do this.
    I have a lot of data in a table. During an evaluation of the data in a meeting I want to change the color of the text depending on the result of the meeting. (for example: High risk = CTRL+R makes the text red).
    I know how to change the color using a button, but I do not want to add a button after each cell. For this reason I would like to do it on a key combination that alway refers to the active cell.
    Many thanks for your help in advance.

    Hi,
    I don't think you can use the ctrl key like that as those shortcuts will be intercepted by Reader (ctrl-R toggles the ruler display on / off).  You also might have trouble updating the color while you still have focus on it.  You can use the shift key in a similar way, so if you only have lower case characters in the text fields then you can do something like;
    if (xfa.event.shift)
        switch (xfa.event.change)
            case "R":
                this.fontColor = "255,0,0";
                break;
            case "O":
                this.fontColor = "255,102,0";
                break;
            case "G":
                this.fontColor = "0,255,0";
                break;
        xfa.event.change = ""; // ignore character
    If you need uppercase characters maybe you can have one button to set "review mode" and test that on the if (xfa.event.shift) line.  But again it wont take effect until you have tabbed out of the field.

  • I used Duplicate Annihilator to isolate dups in iPhoto on my iMac. At the end it told me it had marked the word duplicate in the comments / description field. How do I find and delete the marked photos?

    I used Duplicate Annihilator to isolate dups in iPhoto on my iMac. At the end of its search, it told me it had marked the word duplicate in the comments / description field. How do I find and delete the marked photos?

    File -> New Smart Album
    Description -> contains -> Duplicate
    will find them.
    Then the keystroke to delete depends on which version of iPhoto you have. All the keyboard shortcuts are under the Help menu.

  • How to set the Background Color of a Text Field in a Tabular Report.

    Hello,
    I tried to set the Background Color of a Text Field in a Tabular Report.
    But I was not able to change this colur.
    In the report attributes --> column attributes
    I tried already:
    1. Column Formating -- >CSS Style (bgcolor: red)
    2. Tabular Form Element --> Element Attributes (bgcolor: red)
    but nothing worked.
    Can anybody help me?
    I Use Oracle Apex 2.2.1 on 10gR2
    thank you in advance.
    Oliver

    in "Report Attributes" select the column to move to the "Column Attributes" page. In the "Element Attributes" field under the "Tabular Form Element" region enter
    style="background-color:red;"
    I will also check if there is a way to do this via the template and post here again
    edit:
    in your template definition, above the template, enter the following:
    < STYLE TYPE="text/css" >
    .class INPUT {background-color:red;}
    < /STYLE >
    (remove the spaces after the < and before the >)
    change "class" to the class that the template is calling
    (I'm using theme 9, the table has: class="t9GCCReportsStyle1" so I would enter t9GCCReportsStyle1)
    A side-effect of using this second version is that ALL input types will have a red background color--checkboxes, input boxes, etc.

  • It possible using javascript to change the value of another jsf text field?

    In my case, I have an input text field and would like to copy it's value on the onchange() event into another text field. Using the destination text field's Id and assigning some content with it's .value property

    Woodstock apparently renders some Javascript/DOM with some homegrown widget framework which on its turn renders the HTML DOM tree instead of plain vanilla HTML. Correct me if I'm wrong, to confirm this, just view the generated HTML source of the page.
    After some Googling I found out that you need getProps() and setProps() to get and set element attributes respectively.
    [http://google.com/search?q=webuijsf+domnode+site:sun.com].
    If you stucks with this, I recommend you to post this question at a forum or mailinglist devoted to Woodstock, e.g at their own homepage at dev.java.net or the Netbeans forum at nabble.com. You're here at a Sun JSF forum, not at a Woodstock forum.

  • I have two fields and I would like the 2nd field to display the word "Error" if the number is smalle

    I have two fields and I would like the 2nd field to display the word "Error" if the number is smaller than the number in field 1.
    can any one help?

    The code for the field? Sure, it's simple.
    You can use something like this as its custom calculation code:
    var v1 = this.getField("Field 1").valueAsString;
    var v2 = this.getField("Field 2").valueAsString;
    if (v1 && v2 && Number(v2)<Number(v1)) event.value = "Error";
    else event.value = "";
    Edit: Fixed code

  • How to remove the words such as the, is , are, and or  from text file

    my problem is
    i want to make an application to do that
    eceives a test file from the user, this file contains a list of words , the program must do the following
    1- Remove the words such as the, is , are, and or
    2- Count the number of occurrences of each word
    3- Display a two column message, the first column contains a word and the second column contains the number of repetitions of this word
    i make number 2 and 3 how can i do number 1

    I would accumulate word frequency in a Map<String, Integer> -- is that what you are doing? But before processing a word I would check to see if it is contained in a Set<String> of common words. In which case further processing of the word is not required.

  • Is it mandatory to assign language key to all the words exist in the syste

    Hai experts plz clarify my dout,
    Current Scenario: We are in the Scan phase of the Combined Upgrade and Unicode Conversion.
    Our questions:
    1.      Is it mandatory to assign language key to all the words exist in the system? When we tried, without assigning a language key, still we were able to proceed to the next step.
    2.      Now the upgrade has started, so confirm us that whether it is necessary to assign the language key for all the words without a language assignment before export or SAP considers SPACE as a language character? This question is raised because in MDMP systems there is 1 column with Space.
    3.      For words with mix characters what is the language to be assigned? Mix characters eg: “a#p//e”
    4.      How such words are generated? Usually words are generated from table CDPOS where the field: table key has a provision to store binary numbers and the when system doesn’t recognize the characters given at the input, an ambiguous word is generated and it is stored in the vocabulary list. Hence what language is to be assigned to this word?
    There are 21,000 such words without language assignment in the Vocabulary.

    Hello!:
    1. It's mandatory, to do all correctly.
    2. You have to do all the scan's for the MDMP.
    3. I've put German (the original lang)
    4. 21195 in my case, it's normal. The total number of tables is 27265.
    Please confirm the message, and points (you can contact with be by email)
    Regards,
    Alfredo.

    Hello Vinay!:

  • Comparing the BOM usage with the actual usage for materials.

    Hi All
    My client want to compare the BOM usage with the actual usage and have a report for this within a period? More specified they want to calculate the BOM usage, based on the requirement quantity from confirmation - but with out the scrap %. mulitplied with the confimed quantity of the header material.
    The actual usage should be based on  goods issuing from stock, either as goods issue to order (backflushing) or as goods issue to cost center. 
    I havent been able to indentiy a standard report for doing this - does some of you know a standard report?
    -  I was thinking of the following method:
    Look at  tabel RESB and compare it  with MSEG, but I have some diferent problems with this.
      - In resb there is no qty before scrap. 
      - The data amount from MSEG, is so huge so it is not possible to make a data search for a whole period (eg. month)
    Br. M

    There is one std report MCRX which gives a comparison of quanity in order and actual consumption,
    if it doesnt meet your need, you may have to create a custom report.
    logic can be find the quantites as per BOM for the produced quantities
    issued quantities to the order
    tables you may need are AUFK AUFM
    AFKO, STAS STPO
    MSEG, MKPO
    JEST ( if you want to filter using order status)

  • Can't get the video to work on my ipad 7.0.2...camera works...has the word "video" on the camera screen but no open when I touch it.

    Can't get my ipad to take videos...since it has the word "video" on the camera app I would have thought it would take videos. -  I touch the spot. ...NO video!  I guess this ipad doesn't have video capability. ??

    Try sliding the words instead of tapping them.

    I updated my mini, but some of my apps are no longer available. One of them I purchased from the Apple store.  They are grayed out with the word "waiting" underneath the app.  Any suggestions?

    If there are multiple apps trying to download at once, only one can download at a time and the rest say "Waiting" until it is then their turn. Try this. Double tap the icon of the Waiting app, and it should resume the download.

    Another thing to try - Turn the iPad Off & then back ON.
    If that doesn't work:
    •  Log out of your iTunes store account.  Go to Settings > Store > Sign Out Then press the Home button.
    • Then press and hold the Home and Sleep buttons simultaneously and don't release them when it brings up the Turn Off screen; keep holding them until the Apple logo appears.
    • After restart, the Waiting should be gone.
