Limit number of characters in a text cell

Hi Numbers Community,
Is there a way to put a cap on the number of characters that can be written into a cell with Data Format set as Text?
Thanks for your help!

There doesn't seem to be a way to keep you from going over a limit on the number of characters in a cell but you can use Conditional Highlighting to alert you when you do go over the limit. This, for example, sets the background color of cell B9 to red if there are more than four characters in cell A9:
The formula in B9: =LEN(A9)

To limit number of characters in a text field...

I did a little research. My goal is to limit the number of characters in the textfield by 50.
If the results of my research are correct, I have to create a JFormattedTextField, then use a MaskFormatter with a mask of 50 asteriks. Is that correct? Any other suggestions?
Thanks in advance.

I've got a problem using a JFormattedTextField.
Each time the the text field gains focus, the caret does no move to the end of the text. It appears at the start of it. plus, any text i typed will overwrite the character already typed in, as if you've pressed the INSERT button during typing in a text editor.
What caused that and how do I resolve it?
Thanks a lot for the help ;)

How do I limit number of characters in a JTextField?(different from others)

Hi,
I know this question has been posted several times on this forum, but my question is actually a different one. So please read.
I have the following code that puts two JTextFields in a JFrame. I want to limit the number of characters in the first JTextField to three characters. What's different about my question from other solutions provided, is that I don't want to be able to type more than three characters in the JTextField, and then not be able to get out of JTextField unless I have three or less characters. What I do want, is to have maximum of three characters, not be able to type the fourth, and have access to the other JTextField at all times.
I have tried the following solution of setting an InputVerifier to my JTextField, but it hasn't worked, since I can still type the fourth character.
Looking forward to your help!
Thanks.

}

Thanks, JayDS! Your suggestion worked. And I've come up with the following code with help of your suggestion. However, I'm not happy with the fact that I see empty spaces in my JFormattedTextField when I don't have anything entered in it, or when my textfield has focus and I click it again. Also, I'd like the text alignment to always stay on the right, even if I have less than 3 digits.
Could you please help me out with that?
Thanks!

Coding - returning the number of characters in a text box.

I am in the process of creating a cell phone simulation/animation in Edge Animate CC for use in a Captivate course. Basically, when a user clicks on number buttons on the virtual keypad, it displays the numbers in a text box , just like an actual cell phone would display the phone number on the screen as a caller is dialing. So, the user would click seven buttons and a seven-digit phone number appears on the virtual phone screen. This part of my animation works great and all seven digits appear, but I would like to modify the code so that a hyphen appears after the third button clicked. This way, the output better resembles an actual phone number instead of just a string of seven digits.
Here is an example of the code I currently have assigned to the #2 button on the virtual keypad:
var text = sym.$("PhoneNum").html();
text = text + 2;
sym.$("PhoneNum").html(text);
PhoneNum is the name of my text box on the stage where the digits appear as each keypad button is clicked.
In order to incorporate the hyphen after the third button clicked, I need to somehow return the current number of characters in the PhoneNum text box, then create an if/else scenario that applies the hyphen after the third button clicked.
Does anyone know how I can use either JavaScript or jQuery to return the number of characters currently in the PhoneNum text box?

No problem!
Basically the thing to remember is that unless you are needing to pass html to the object, you can use text() instead. text() also gives you the raw text without any html formatting (so you can assume what .html() would return)

Limit number of characters in a textbox

I'm trying to limit the number of characters a user can enter into the text box on a form.
Any help is appreciated.

Thanks.
I found this code, but am having problems using it (specifically the keyascii as integer part):

' Note: Requires LimitChange() in control's Change event also.
If Len(ctl.Text) - ctl.SelLength >= iMaxLen Then
If KeyAscii <> vbKeyBack Then
KeyAscii = 0
Beep
End If
End If
Exit_LimitKeyPress:
Exit Sub
Err_LimitKeyPress:
Call LogError(Err.Number, Err.Description, "LimitKeyPress()")
Resume Exit_LimitKeyPress
End Sub
Sub LimitChange(ctl As Control, iMaxLen As Integer)

Number of characters in long text functionality

Can anyone please help me as to how many characters are there in long text functionality in Standard SAP. If we create a document under FB01 , there is a long text field how many characters we can enter in that text field.
Also can we have any number of characters in custom field or is there any restriction to it.

Hi Isha,
Please refer the solution for your problem on this link :
Here i have explained in detail how you can go about with providing Custom Controls on the screen.

Limit number of lines in a text editor

Hello.
In my program, i'm creating a text zone and i need to limit the data users will put in this zone.
To create that, i'm using the object cl_gui_textedit. I've looked in the methods of this object but i wasn't able to find one that will limit the number of lines of the text editor.
Did i miss it ? Does anybody knows how i can for example limit the input zone to 5 lines ?
Thanks for your help.
Here's my code
IF g_editor IS INITIAL.
*   Instanciation du container pour la zone de texte
    CREATE OBJECT g_textedit_custom_container
        EXPORTING
            container_name = 'TEXTEDITOR'
        EXCEPTIONS
            cntl_error = 1
            cntl_system_error = 2
            create_error = 3
            lifetime_error = 4
            lifetime_dynpro_dynpro_link = 5.
    IF sy-subrc NE 0.
*      add your handling
    ENDIF.
*   Création de la zone d'édition du texte
    CREATE OBJECT g_editor
      EXPORTING
        parent        = g_textedit_custom_container
        wordwrap_mode = cl_gui_textedit=>wordwrap_at_fixed_position
        wordwrap_position          = 68
        wordwrap_to_linebreak_mode = cl_gui_textedit=>true.
ENDIF.

I just notice there is a method SET_HEIGHT but this one is implemented in CL_GUI_CONTROL.
I tried this :
        CALL METHOD g_editor->set_height
                EXPORTING height = w_height.
But in fact, i never enter the method.
Do i have to create a CL_GUI_CONTROL object ? If yes, how do i link it to the CL_GUI_TEXTEDIT.
Sorry if some questions mays seem obvious. It's my first object abap program.

Limit number of characters in a JTextField

Now I know that this question has been asked very often but the answers that have been given do not always work. According to other posts you can either use a KeyListener or a DocumentListener. The problem with the code that I have seen using a KeyListener is that you can't use the backspace key when the limit is reached. I am using a JTextField and all the answers dealing with Documents use a JTextArea and I can't figure out how to get it to work with JTextField. I don't understand why the Swing package just didn't come out with a method or cunstructor for these components to limit the number of characters. It would simplify things a lot. I need a JTextField to allow only 25 characters and allow backspaces. Thanks

Here is the code that I am using. It seems to be working somewhat. The only problem now is that when you type the 26th key that new key overwrites what is in the 25th position. Is this the correct way of doing it and if so how do I get it to quit adding in the key that was just pressed?
user_box.addKeyListener(new KeyAdapter() {
    public void keyPressed(KeyEvent e) {
     if((user_box.getText().length() > 24)&&(e.getKeyCode() != KeyEvent.VK_BACK_SPACE)) {
//     System.out.println(e.getKeyCode());
     e.consume();
     try {
          user_box.setText(user_box.getText(0,24));
     }catch(Exception ex) {}
     Toolkit kit = Toolkit.getDefaultToolkit();
     kit.beep(); //system beep
});

APEX Supplied HTML Editor (fckeditor) - Limit number of characters

Hi
Has anyone found a way of limiting the number of characters allowed in the HTML Editor that is supplied with APEX (3.1/fckeditor)
I have had a look at the fckeditor web page and found a couple of plugins but I fear that this approach will require me to manually implement fckeditor, and not use the inbuilt one.
I would also prefer to not do this with an application process as the user can overflow the editor and get the HTTP-400 Value param too long error.
Regards
Matt

Dribble!
does this help? Is their anyway to limit the character count on a textarea with html editor

How to limit number of characters in a JTextField?

Hi,
I am new to java and I would like to create a JTextField which only allows the users to enter no more than 32 characters. How do I do that? I am looking for a "set..." function but cannot find it.
Thanks for any hint.

Unfortunately there's no setXXX() method that will do it. You'll need to create a new document class that will accomplish what you want. See attached sample working code.
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;
public class Limit {
public static void main(String args[]) {
new LimitFrame();
class LimitFrame extends JFrame {
JTextField jtf = new JTextField(10);
LimitFrame() {
super();
jtf.setDocument(new LimitDocument(5));
/* Components should be added to the container's content pane */
Container cp = getContentPane();
cp.add(BorderLayout.NORTH,jtf);
/* Add the window listener */
addWindowListener(new WindowAdapter() {
   public void windowClosing(WindowEvent evt) {
    dispose(); System.exit(0);}});
/* Size the frame */
pack();
/* Center the frame */
Dimension screenDim = Toolkit.getDefaultToolkit().getScreenSize();
Rectangle frameDim = getBounds();
setLocation((screenDim.width - frameDim.width) / 2,(screenDim.height - frameDim.height) / 2);
/* Show the frame */
setVisible(true);
class LimitDocument extends PlainDocument
int limit;
public LimitDocument(int limit)
this.limit = limit;
public void insertString(int offset, String s, AttributeSet a) throws BadLocationException
if (offset + s.length() <= limit)
   super.insertString(offset,s,a);
else
   Toolkit.getDefaultToolkit().beep();
}

How to validate the number of characters in Text Entry box?

Hi
I have inserted a text entry box and assigned a variable (UserName) to it. Now, I need to limit the entry to a maxinum number of 20 characters. In other words, how do I validate the number of characters in the text entry box and provide feedback if it is more than 20 characters?

Thanks.
I have posted this as a query on the relevant post on Jim's website. I am too new to regular expressions. I hope he will help with an example as well.

Minimim characters in a text box

It seems silly that it is so easy to set the maximum number of characters in a text box (ie. Properties>Options>Limit of X characters) but that there is no easy equaivalent for minimum characters? At least not in Acrobat 9 anyway, don't know about the never versions!
Does anyone know if the minimum number of characters can be set with Javascript?

That was intended to be a rhetorical question. So what you really want is if the field is not blank, that there should at least be some minimum number of characters. What is the minimum number that you want to enforce? Youd probably want to use a custom validation script for this, but what exactly do you want to happen if the user only enters three characters but the minimum you want is four? Should the three characters that were entered be rejected altogether, or should the focus just be set back to the field so the user can enter more, or something else?
Here's what a script that rejects the entry might look like:
// Custom validate script for text field
(function () {
    // Allow nothing
    if (!event.value) return;
    // Set the minimum number of characters
    var min_chars = 4;
    // Reject the entry and alert user if fewer than the minimum
    if (event.value.length < min_chars) {
        event.rc = false;
        app.alert("Please enter at least " + min_chars + "characters.\r\rYou entered " + event.value.length + " characters.", 1);

Reading in a certain number of characters from a file.

Hi guys,
I need some pointers on how to read in a specified number of characters from a text file.For example,how would I read in the first 100 characters to an array from a text file with an unspecfied number of characters (more than 100 rather than less!).
At present I am getting code errors being thrown due to reading in beyond the array size ie
java.lang.ArrayIndexOutOfBoundsException: 100.

post more code , this exception tells me nothing
without seeing what you are actually doing.
public String getText (String file)//textfile to be analyzed will be inputted as argument 150407 0356
   //15042007 0612 Check notes on overloaded getText method below.
       int temp;
       inputFile = file;
       int i=0;
            try
                BufferedReader bGetFile = new BufferedReader (new FileReader(inputFile));
                while ((temp=bGetFile.read())!=-1)
                    textFromFile[i] = (char)temp;
                    i++;
                /*for (int j=0;j<MAX;j++)
                    System.out.print(textFromFile[j]);//25042007 0208.For Testing purposes
                inputText=new String(textFromFile).trim();
                bGetFile.close();
            catch (IOException e)
                System.out.println (" ");
                System.out.println ("Sorry.An error occurred while trying to read from the input file.Unable to proceed!");
            System.out.println ("Processing the input text file "); //25042007 2318 being used for debugging purposes.
            return inputText;
    }If the file being read is greater than MAX characters it will throw the exception mentioned.What I would like to do is read in MAX characters and discard the rest.

Is there a way to set a limit on the number of characters each cell will hold in numbers?

Hi there, I'm creating a CSV file via Numbers and would like to set a limit to the number of characters a cell will hold in numbers. This way, when I copy text from my source, and paste it into the numbers cell, the text will be cut off at the character limit I've placed for that cell.
Specifically, I would like my character limit per cell in a column on a new spreadsheet to be 100 characters. I have text to copy & paste into roughly 10 different cells and I'd like it to all be 100 characters.
I am using Numbers version 9 of iWork and 10.7.5 OS.
Any help is appreciated.

Thank you t quinn for your reply as I do really appreciate the help.
I don't quite understand what your suggestion was and before I try to figure it out and play around with numbers, I thought I should clarify further. When i wrote I want to paste the content into the cell and have it limited to 100 characters I was mis-spoken. I actually have all the content already in the columns in a spreadsheet and would now like to just limit some of the columns to hold only 100 characters in a cell so that when its a CSV file it will be accepted to the program I'm trying to upload it to.
SO does that change the way you can answer my question?
Is there a way to just limit the content currently in a spreadsheet to 100 characters per cell?
Kindly

Limit the number of characters in Text Components

I'm trying to limit the number of characters in text components. So I use the follow KeyListener:
private class KeyHandler extends KeyAdapter{
String oldText;
private KeyHandler(){ }
public void keyTyped(KeyEvent ev){
String newText = textField.getText();
System.out.println("Old text: " + this.oldText); //debug
System.out.println("New text: " + newText); //debug
if(newText.length() < limit){
this.oldText = newText + ev.getKeyChar();
}else{
textField.setText(this.oldText);
if(textField.getCaretPosition() + 1 > limit)
textField.setCaretPosition(limit - 1);
But the problem is that after that, the last key is typed in the component and the last key always appear.
�Does anyone know the way for consume the key presses?
Thank you

(Belongs in the Swing forum.)
The callback method keyTyped comes after keyPressed and keyReleased.
The event.consume() should consume the event.
Consider cut/copy/paste.
Maybe a addPropertyChangeListener would be better?
