Ask about how to append text on next line
I'm writing lingo about log file. For example, i would like
to write like this when a new entry is appended:
etc 3/29/2007 8:34 PM
etc2 3/29/2007 8:34 PM
Here is the lingo:
on mouseUp
if objectP(myFile) then set myFile = 0 -- Delete the
instance if it already exists
myFile = new(xtra "fileio") -- Create an instance of FileIO
openFile(myfile, the moviePath&"try.txt",0) --Open the
file with R/W access
myVariable = readFile(myFile)
setPosition(myfile,getLength(myFile)) -- Set position to end
of file
writeString(myFile, " " & "etc" & " " &
_system.date() & " " & _system.time()) -- Append text to
the file
closeFile (myfile) -- Close the file
myFile = 0 -- Dispose of the instance
end
The problem is the appended text is put together, instead of
a line by a line. In fact, what I want is the appended text is put
into next line everytime, not on the same line. Please help me to
modify it, thanks.Try changing this line:
writeString(myFile, " " & "etc" & " " &
_system.date() & " " &
_system.time()) -- Append text to the file
to
writeString(myFile, " " & "etc" & " " &
_system.date() & " " &
_system.time()&RETURN) -- Append text to the file
Note that if you open the file inNotepad on a PC, it will
look strange
because of the way notepad handles line feeds. You can get
around it by
doing this:
winReturn = NumToChar( 13 ) & NumToChar( 10 )
writeString(myFile, " " & "etc" & " " &
_system.date() & " " &
_system.time()&winReturn) -- Append text to the file -
How to append text of one JTextPane to another JTextPaneacross the network.
i am developing a chat software using client server architecture. i have a JTextPane on client end where the client types the message in multi colour,multi font and multi size formats. i can send the data to other clients but then i cannot send this formats in which the client wants to send the data. how should i achieve it. when i make the content type of the JTextPane then whatever client types it shows up properly but if i change the content type to text/html then what ever i try to type it just shows an <html> tag and doesn't show the text that the client types. i tried using the second content type with the idea of sending data to the server in html format so that when other clients JTextPane get it then it should display it that way. but it doesn't happen that way. ne suggestions?

Hi, may anyone tell me how to append text to a file's end?
every time when i using FileOutputStream.write(byte[]) to add text to a file, the old content would be disappear. but my intention is append, not affect the old content. how to?
thanxassuming it is a text file, read the text into a Reader, read the Reader's contents into a StringBuffer, close the Reader, append to the StringBuffer the new text and write it down to the file.

Can someone tell how to append text to a logfile?
I use this function, but all existing text is always destoyed:
function schrijf_naar_log(bestandsnaam){
var log_bestand = File((Folder(bron_map)) + "/log.txt");
log_bestand.open("e");
log_bestand.writeln("\r\n" + bestandsnaam);
log_bestand.close();
MichelAfter opening for edit, you need to advance the "current position" in the file to the end using seek:
log_bestand.seek(0.2);

StyleConstants.setBackground(style, Color.blue);
StyleConstants.setForeground(style, Color.white);
// Append to document
g.kit.insertHTML(g.doc, g.doc.getLength(), "tekxt", 1, 1, HTML.Tag.B);
//g.doc.insertString(g.doc.getLength(), "<b>Some Text</b>", style);
} catch (Exception e) {
System.out.println(e.getMessage());
If i use insertHTML method then there is no text on the text area.
If i use insertString method then text appear but it doesn't resolve html tags.
Please help.I did something like this:
public
class GUI
extends JFrame {
//previous code - no changes
public static void main (String [] args) {
GUI g = new GUI();
StringBuffer buf = new StringBuffer();
try {
buf.append("<b>bb</b>");
buf.append("<b>ccc</b>");
// First append to document
g.pane.setText(buf.toString());
//Second append
buf.append("<b>ddddd</b>");
g.pane.setText(buf.toString());
} catch (Exception e) {
System.out.println(e.getMessage());
I know that this method is not smart and doesn't look good, but it works.
If you know how to append html using HTMLEditorKit and HTMLDocument please write some example. -
How to get the bold texts in JTextPane?
How to get the bold texts in JTextPane?
I believe you need to look at the Elements of the Document. Use the Document.getDefaultRootElement() method to get the first root Element. From there you can iterate through all the Elements. You should then be able to check the attributes of the element to see if it contains the Bold attribute using something like:
AttributeSet attributes = element.getAttributes();
if ( attributes.containsAttribute(StyleConstants.Bold, Boolean.TRUE)

How to get the current location text in JTextPane
hi
i want to get the current location text in JTextPane ...iam useing
caretPos = jtpMain.getCaretPosition();
iam geting the current Locations at the same time i want to read the entery current line
i used like this
StartPos=jtpMain.getText();
but iam geting entry data in JTextPane ... how can get current Locatin data ...
pls help meIf I understood your request, what you would like to do is to be able to retrieve Start and End Positions of a given line (a line and NOT the whole content of the JTextPane).
JTextPane is a graphical component that is bound to a logical document. Documents are structured in elements. What defines an element is up to you to decide if you extend your own document but elements are by default paragraphs (runs of text ended by a carriage return '\n' character). So, I think that what you want to do is to retrieve the Start and End positions of the
paragraph over which the caret is currently positionned. Then I think you have got to do the following :
int intStartPos;
int intEndPos;
int intCaretPos;
javax.swing.text.StyledDocument docStyledDoc;
javax.wing.text.Element eleParagraph;
intCaretPos = jtpMain.getCaretPosition( );
//Get a reference to the default styled document bound to the JTextPane component
docStyledDoc = jtpMain.getStyledDocument( );
//Get the paragraph element from the document over which the caret is positionned
eleParagraph = docStyledDoc.getParagraphElement(intCaretPos);
//Get paragraph's offsets
intStartPos = eleParagraph.getStartOffset( );
intEndPos = eleParagraph.getEndOffset( );

if(cb.getSelectedItem=="medium")
cb.setAction(new StyledEditorKit.FontSizeAction("double click", 14);)
if(cb.getSelectedItem=="large")
cb.setAction(new StyledEditorKit.FontSizeAction("double click", 16);)
this code is not working properly according to the action i set on comboBox.
when i select medium the previously set action on comboBox works like small action work.
when i select large the medium action starts .
means its not working in correct time when i select item of combox n action of that item is not working at that time..
plzz plzz help me:(Action action1 = new StyledEditorKit.FontSizeAction(
"double click", 12);
Action action2 = new StyledEditorKit.FontSizeAction(
"double click", 14);
Action action3 = new StyledEditorKit.FontSizeAction(
"double click", 18);
s2 = (String) cb7.getSelectedItem();
if (s2.equals("Small")) {
cb7.setAction(action1);
e1.setSource(cb7);
} else
if (s2.equals("Medium")) {
cb7.setAction(action2);
e1.setSource(cb7);
} else if (s2.equals("Large")) {
cb7.setAction(action3);
// e1.setSource(cb7);
when i chooze any combobox item then according to that item i set the Action on ComboBox but that action is not working properly on the selected text in the JTextPane..means selected text in JText Pane is not changes its Size according to the comboBox selected ITEM.

How to listen and obtain caret positions of changed text in JTextPane?
Hi,
I have a JTextPane that displays text with some styles on particular words in the text. For example, I highlight words with red color if they are in my dictionary file. I use regular expression to find matches, replace them with their corresponded definitions, and call setCharacterAttributes to add styles to the definitions. I store all start and end caret positions of the matched words/definitions in a vector. So, I can redisplay styles of all previous matches.
The problem is that I'd like to be able to edit the text of some previous matches. So, with those changes all caret positions that I already store in the vector need to be updated.
How can I obtain caret positions of changed text in JTextPane?
How can I know that a user is currently changing text in the JTextPane?
How can I get style of text such as color that is being changed?
Thank you very much.Thank you very much, camickr, for your reply.
I think that I might not know the right way to handle JTextPane and Document object.
What I have done are:
- Add style to JTextPane using, for example,
Style targetCurrentMatchStyle = this.targetWindowTextPane.addStyle("Red", null);
StyleConstants.setForeground(targetCurrentMatchStyle, Color.red);//For highlight - Then, I use regular expression (Pattern and Matcher) to find a match in text. For each match, I get start and end position from matcher.start() and matcher.end().
if(matcher.find(start)){
String term=matcher.group();
int start=matcher.start();
int end = matcher.end();
//find definition for the matched term.
String definition=mydictionaryHash.get(term);
//Store caret positions in lists
startPositionList.add(start);
matchedLength=lengthList.add(definition.length());
//Add changed to text in textpane
StringBuffer sb=new StringBuffer();
matcher.appendReplacement(sb, definition);
matcher.appendTail(sb);
//Get translated text from StringBuffer after replacement
String translatedText=sb.toString();
targetWindoTextPane.setText(translatedText);
//Update start position for next search
start=start+definition.length();
//Add style to matched regions below.
}- From the lists of start positions and matched lengths, I use the following code to add "Red" color to the matched text regions including all previously matched.
for(int i=0;i<startPositionList.size();i++){
this.targetWindowTextPane.getStyledDocument().setCharacterAttributes(
startPositionList.get(i),
lengthList.get(i),
this.targetWindowTextPane.getStyle("Red"),
true);
}My issue is that I'd like to be able edit previously matched regions and update all positions of the matched regions stored in the lists. -

How do you set the line spacing when using the Append Text Table to Report VI?
I have a table of numbers which I wish to print using the report generation VI's. Since each column has a different numerical format, I first convert the number for each cell to a string with the appropriate format and then build a string array to pass to the Append Text Table to Report VI. The table is printed with double line spacing. How do I reset this for single spacing?
Attachments:
print_array.vi 112 KBDave,
The issue is not with the NI-Reports functionality, but the Array to Spreadsheet String funvtion in the for loop. Here is the context help for this function:
"Converts an array of any dimension to a table in string form, containing tabs separating column elements, a platform-dependent EOL character separating rows, and, for arrays of three or more dimensions, headers separating pages."
The thing to note here is that it says it adds an EOL (end of line) character at the end of every row. This is what is happening. Your first column of data has a \r\n in it and adds the second row to each data item. This in turn makes the rest of the columns have a larege blank space at the bottom so that all of the cell heights are equal. I w
ould re-write that little bit of code so that you just do one large string concatenation of number, spaces, number, spaces, number and this should solve your issue.

How do I append text to linux console
I am quite familiar with java, I just wondering how can I append text to linux prompt like login and password.
I hope anybody can help me.
Thank a lot, I'm not really expert in Java

Edited by: jahidi on Apr 19, 2008 2:23 PMI'm not completely sure I understand the question... The prompt is really part of the shell, and you would change it there (but not usually by adding password information!)
You can read what the user enters at the console with System.in and write your own output there using System.out.
