Counting number of characters in a textbox

I am keen to no, what is the best way to specify a number below a textarea, which countsdown each character entered till it reaches 0 then the user cannot enter any more characters?
Thanks,
Steve

Method to count number of characters in a string?

hi.
i'm trying to write some script that will count the number of characters in a string passed into a constructor and then compare it against another value to check whether the string passed in is valid.
something like this
public class Stringcheck
public static int maxStringLength;
public static double minSize;
public static boolean testStringLength(String x)
// Insert method for counting number of chars in String x and name as 'int numberOfChars
if(number of Chars <= maxStringLength )
return true;
else
return false;
can someone help me with writing this script.
Thanks
Richard.

ummm, you dont need anything fancy. try:
String test = "this is the test string";
int length = test.length();

Count number of Characters in CLOB field

Hi all,
I posted this on another database, but I think it really belongs here. I have a CLOB field that stores reports in HTML markup languate. Here's an example of a report.
 </title> </head> <body contenteditable="true" text="#000000" bgcolor="#ffffff"> this is a test for a bilateral modifier </body> </html> 
I'm trying to provide a query that counts the number of characters that is not a HTML tag nor whitespace. I've attempted to use a combination of the length and replace function which first replace all HTML tags and whitespaces with nothing and then uses length to calculate the number of characters. Here's what the function looks like.
 length(trim (both ' ' from replace (replace (replace(replace (replace(replace(replace(replace (replace(replace(replace (replace(replace (replace(reports.report_text ,'</head>',''),'</title>',''),'<body contenteditable="true" text="#000000" bgcolor="#ffffff">',''),'</body>',''),'</html>',''),'',''),'',''),'',''),'',''),'',''),'',''),'',''),'',''),'>','')))
 
For the example above, the number of characters counted in the outputs is 66, which is clearly incorrect. I need to only count these characters for the example above "thisisatestforabilateralmodifier", but there is still white space that remains after I do the sequence of replaces. If someone can help, it's be greatly appreciated. Thanks.

If you can convert your html string to valid xml you can do the following:
michaels> SELECT str, LENGTH(REPLACE(REPLACE(XMLTYPE (str).EXTRACT ('//text()').getclobval(),CHR(10)),' ')) length
FROM (SELECT
'<html>
<head>
<title></title>
</head>
<body contenteditable="true" text="#000000" bgcolor="#ffffff">
 this is a test for a bilateral modifier
</body>
</html>' str FROM DUAL)
STR LENGTH
<html> 32
<head>
<title></title>
</head>
<body contenteditable="true" text="#000000" bgcolor="#ffffff">
 this is a test for a bilateral modifier
</body>
</html> Otherwise regex_replace would be an alternative (on 10g).

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):
Sub LimitKeyPress(ctl As Control, iMaxLen As Integer, KeyAscii As Integer)
On Error GoTo Err_LimitKeyPress
' Purpose: Limit the text in an unbound text box/combo.
' Usage: In the control's KeyPress event procedure:
' Call LimitKeyPress(Me.MyTextBox, 12, KeyAscii)
' 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)
On Error GoTo Err_LimitChange
' Purpose: Limit the text in an unbound text box/combo.
' Usage: In the control's Change event procedure:
' Call LimitChange(Me.MyTextBox, 12)
' Note: Requires LimitKeyPress() in control's KeyPress event also.
If Len(ctl.Text) > iMaxLen Then
MsgBox "Truncated to " & iMaxLen & " characters.", vbExclamation, "Too long"
ctl.Text = Left(ctl.Text, iMaxLen)
ctl.SelStart = iMaxLen
End If
Exit_LimitChange:
Exit Sub
Err_LimitChange:
Call LogError(Err.Number, Err.Description, "LimitChange()")
Resume Exit_LimitChange
End Sub

Looping assistance (counting number of characters in a variable)

Good morning, all! I was wondering if anybody could take a look at this small, easy project I was working on today. I've searched the net for an answer and while it was useful and I learned a few things, nothing is really working. The code is pretty self explanatory, infact, I'm embarrassed I do not know how to do this, because I'm sure I know. Basically, counting the length of the variable is not working. The output is supposed to be as many times as the input is long in characters (I hope that makes sense!) Anyways, if you could take a look and tell me if you see anyway I could fix this, I would appreciate it.
import java.util.*;
import javax.swing.JOptionPane;/**
* @author Willaim
public class Loop {
 * @param args
 public static void main(String[] args) {
 String loopInput;
 int count;
 loopInput = JOptionPane.showInputDialog("Please enter a word for the loop demo: ");
 while(count < loopInput.length){
 System.out.println("" +loopInput);
 count = count + 1;
 for (count = -1; count < loopInput.length; ++count){
 System.out.println(loopInput);
 do {System.out.println("loopInput");
 count++;
 }while (count < loopInput.length);
 }

1) to get length from a String, you must use a method and all methods end in parenthesis (arrays are different in that you are getting the length field, and this doesn't require parenthesis.
2) You probably don't want to use this "count" variable. You will probably be better with a for loop here since the number of iterations through the loop is defined in advance.
Also, when posting your code, please use code tags so that your code will retain its formatting and be readable. To do this, either use the "code" button at the top of the forum Message editor or place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
// your code block goes here.
// note the differences between the tag at the top vs the bottom.
[/code]or
{code}
// your code block goes here.
// note here that the tags are the same.
{code}

How to count number of characters in a string?

Hi
I need to display values in a script. but the alignment getting distrubed if it is less than 20 charaters, for exmple material descirption is only displaying 20 characters in script. if it is less than 20 charcters the alignment getting changed.
please help me ...urgent..
thanks in advance...

solution to this problem in script is not to count the characters but to align them based on positions .
1.
Use the tab positions for that paragraph format to display the values in a finite format .
In this u need to give the position start and position end length and use the same in the script as
p ,,&itab-f1&
say my value has to print from position 125mm to 155 mm
i take one tab position for this paragraph format P and maintain the same in the output.
here ,, is the tab position .
See whether it is one character or 20 character it has to behave the same way it should not be misaligned .
check the tab position for that paragraph format in Tabs ..
regards,
vijay.

Count number of characters in a string

Another one for you experts:
Is there a way to count the number of "-" in the strings below:
For instance:

How to count the number of characters

Dear All,
Can anyone tell me a Function Code or sample code to count the number of charactes in a text.
Regards,
Vijay

hi
use the inbuilt function strlen
Number of characters in arg; blanks at the end of data objects with a fixed length are not counted, although they are counted in type string data objects. If you use a non-Unicode double-byte code, a character that occupies 2 bytes is counted twice.
example
data: v_len type i,
v_str type string value 'gggugik'.
v_len = strlen( v_str ).
write:/ v_len.

Counting the number of characters entered into a page item

Is there a way to count the number of characters that are entered into a page item. I've got a field that can contain up to 20 characters. If 20 are entered I can do a = on my search, if less than that, then I have to do a wildcard search. I currently do a substr on the field to see if position 21 is null and position 20 is not null, then I have a 20 character field. Is there a more efficient way to do this and also is there a way to actually show the character count as the page item is being populated

Hello user8014695 (name please),
Try coding the select for your search as
select ...
from some_table
where some_field like case when length(trim(:YOUR_ITEM)) = 20 then :YOUR_ITEM else :YOUR_ITEM || '%' end
Note - I included the trim() assuming blank characters before or after shouldn't count.
To show the character count as the item is being keyed-in, Google "javascript character count" for lots of ways to do this. To work these solutions into ApEx, check the ApEx help/documentation for incorporating JavaScript into your application - specifically the references on accessing page items using JavaScript.
Hope this helps,
John

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

How to set number of characters in input field ?

I am creating an input field dynamically (via CL_WD_INPUT_FIELD).
I am binding the value (via BIND_VALUE) to an attribute with type CHAR30.
I want to give the possibility to enter a number with 4 digits (0 - 9999).
Is it possible to restrict the number of characters that can be entered to 4 (although the BIND_VALUE attribute has a type CHAR30, that allows 30)?
I have tried it via set_length, bind_length but it seems that the length of the BIND_VALUE attribute overrules the length information...

Hi Moritz,
AFAIk you have no other option as using a NUM4 here.
Set Length just sets the lengths of the inputfield according to the current character set ... count of charcters but does not limit the value you may enter
Cheers

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

Is it possible to use NUMCHARS to display the number of characters in a block of text instead of the whole document? How?

Is it possible to use NUMCHARS to display the number of characters in a block of text instead of the whole document? How?

Getting the character count for a paragraph is trivial:
Sub NumChars1()
MsgBox Selection.Paragraphs(1).Range.Characters.Count
End Sub
Even outputting it to the document is trivial:
Sub NumChars2()
With Selection.Paragraphs(1)
.Range.InsertAfter .Range.Characters.Count
End With
End Sub
The real issue comes when you want to update the document. If the destination paragraph is only ever empty or contains the character count of the previous paragraph, you could use:
Sub NumChars3()
With Selection.Paragraphs(1)
.Next.Range.Text = .Range.Characters.Count & vbCr
End With
End Sub
