Monitor changes in text file

I have a text file named Log.txt. I want that as soon as something is written on log.txt a notification is generated instantly. I don't want to use two threads: one that writes and other that reads and generates notification instead I want to use some kind of event generator such that as soon something is written an event is generated in which I will add send notification in the action part. Please guide me its urgent

Hi.
I'm afraid I do not know of any possibility other than periodically polling for changes. As far as I know, e.g. log4j also solves its reconfiguration using a thread checking the last modified timestamp on its configuration file.
Sorry.

Editing and changing large text file

hi,
new to this, so bare with me.
got a large text file 44meg and i need to change some values in it.
example:
TSX ;20030102;40302216;40300579;1980;1900;3762000
i need to change the lines so that they read:
TSX ;20030102;302216;300579;1980;1900;3762000
thus removing the leading 40 in the middle cols.
Thanks in advance
john

crap, small mistake
1) use BufferedReader to read in the file line by line (BufferedReader.readLine())
2a) for each line, split it on the semicolons (String.split())
2b) change the middle value using String.substring()
2c) construct a new line by appending all strings in the array returned by 2a) to eachother
2d) write this new line to a file using PrintStream (PrintSteam.println())
3) when done, close both the reader and the printstream.

Hi all,
we are uplaoding a text file by bdc but when we are importing our text file from some other system we are getting some box type symbol in that text file , how to delete those boxes before uploading it to sap
plz help
regards
sarabjit

Hi,
That is aspecial character you need to remove this special character before you pass this data to BDC....
data: lv_char type x value '0D'.
do.
   if view_fields-value cs lv_char.
     replace lv_char with space into view_fields-value.
     condense view_fields-value.
     modify view_fields index lv_index transporting value.
   else.
     exit.
   endif.
enddo.
here you might have to replace 0D with the correct value whihc you can see in dbug mode by clicking on the hex display button also try with '09 in place of 0D.

Loading a text file into a global variable issue - really a global var?

From all the documentation and examples I can find, it appears that it would be
correct to create a global array variable [outside of any functions] to load image names into,
then use these images for a slideshow. I want to make the app dynamic, in that changing the text file gives a new set of images.
The global variable goes null [no values] after the load event listener. Why is that?
Isn't global, well global, and alive for the duration of the SWF?
PARAMS.TXT:
monthNames=January,February,March,April,May,June,July,August,September,October,November,De cember&dayNames=Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
CODE:
var dNames:Array = new Array();
var mNames:Array = new Array();
var request:URLRequest = new URLRequest("images/params.txt");
var variables:URLLoader = new URLLoader();
variables.dataFormat = URLLoaderDataFormat.VARIABLES;
variables.addEventListener(Event.COMPLETE, completeHandler);
try
variables.load(request);
catch (error:Error)
trace("Unable to load URL: " + error);
trace("2 mNames 2: " + mNames[2]);
trace("2 dNames 3: " + dNames[3]);
stop();
function completeHandler(event:Event):void
var loader:URLLoader = URLLoader(event.target);
dNames = loader.data.dayNames.split(",");
mNames = loader.data.monthNames.split(",");
trace(loader.data.dayNames);
trace("1 mNames 2: " + mNames[2]);
trace("1 dNames 3: " + dNames[3]);
OUTPUT:
2 mNames 2: undefined
2 dNames 3: undefined
Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday
1 mNames 2: March
1 dNames 3: Wednesday
How do I access these values after loading from the external file, after the load?
Thanks in advance.

The statement you quoted from whatever Adobe documentation is correct.
If you want to load the data into the arrays before anything else happens, then have anything else that happens execute via the completeHandler function... after the data is loaded and processed into the arrays.
the command: loadFile() executes before the trace("2:" +images[4]); command. The loadFile function is processed and the loading process BEGINS... but starting the loading does not delay the main processing from continuing down the line--the loading itself becomes a secondary/background task. The command was to execute the loadFile function and the processing of that function was completed. If you don't believe so, then add a trace...
function loadFile():void
     vars.dataFormat = URLLoaderDataFormat.VARIABLES;
     vars.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
     vars.load(new URLRequest("images/fnames.txt"));
     trace("started loading");
If you add that trace, you should see that the loadFile function execution is completed and the next line in your code is then processed... trace(2....)
The addEventlistener does not stop anything. The addEventListener code is assigning a monitor, not a traffic controller... it is telling the monitor to indicate when the data has finished loading. It is not telling anything to stop program execution.
So if you want to wait until the data is loaded before you do anything else... it goes....
function onComplete(evt:Event):void
     var urlVars:URLVariables = evt.target.data;
     images = vars.data.images.split(",");
     tnails = vars.data.thumbnails.split(",");

Find Change through external text file

Hello folks
I am bit pretty in InDesign scripting so could you please look into this.
How can i change any particular text field in Indesign CS3 document from text file.
I do have find change script but for each InDesign document specific text file is assigned.
So each time i have to modify find change GREP property that is also repetetive of work. Is there any way to get find change information should be extract from external text file.
Many Tanks in advance

In the FindChangeByList script, you could customize the function myFindFile(myFilePath) {...} as to search the FindChangeList text file in the document location rather than the script location. That's an example. The question is: given a document, where will you have the corresponding FindChangeList?

Change of a single line in a text file

Is there a option in CVI to change a single line in a text file (.txt), without reading the whole text file into the buffer and writing the whole buffer back after the editing from the one line?

Not that I am aware of.
I'll be glad to know such a function if somebody can point us to it!
Proud to use LW/CVI from 3.1 on.

Why Acrobat x professional is changing the text formatting specifically the font family and the font size of the text in my pdf on exporting it to Microsoft word file format ?How should i stop Acrobat x professional from doing that so that i get an exactly same word file on exporting it from its pdf counterpart?

I was testing the preciseness & efficiency of Adobe acrobat x professional's doc conversion capabilities. As i have to take a document editing project in future which is going to need lot of pdf to word and vice versa conversions . What I did was I created a test word document converted into a pdf using a pdf maker in my word 2007 , Acrobat did convert the document from word to pdf keeping everything in the source file intact , However when i tried the other way round and attempted to convert the same pdf to word 2007 file format I lost my formatting ?So the font that I used to create the pdf are the ones taken from word 2007 which i believe is using the fonts that are installed in my computer. Any suggestions on how to preserve the formatting of the document after converting it from pdf to word file format?

How to effect changes made in a jTable into a text file

i have created a jTable in netbeans6. The table model is DefaultTableModel.
i'm not understanding the concept of firecellupdate and other events listeners.
i want the changes i make to the table during runtime to be written into a Text file.
any help would be greatly appreciated.

any help would be greatly appreciated.you need to add the TableModelListener to your table model.
for example:
model.addTableModelListener(new TableModelListener() {
            public void tableChanged(TableModelEvent e) {
                // TODO Auto-generated method stub
         });then, you need to put your custom business logic(saving data to a text file, etc) into the tableChanged method.
From TableModelEvent you can get all information about the model changes.

Want to change the SQL Server Agent Job History Text Files Location

We have SQL Server 2014 installed on a couple servers, but they were not consistent on directory paths during the installs. I am trying to get the servers to all match.
On one server, SQL Server the Agent Log and Job History files were being written to [H:\Data Root Directory\MSSQL12.MSSQLSERVER\MSSQL\Log].
I want to change that to [H:\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log] to match the other server.
I have ALREADY gone into SSMS - [SQL Server Agent] - [Properties] and changed the "Error Log " "Fle Name" to [H:\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Log\SQLAGENT.OUT]. And that is working great.
In [SQL Server Configuration Manager] - [SQL Server (MSSQLSERVER)] - [Properties] - Startup Parameters entries have been changed to the new path (-d, -e, and -l), and under [Advanced] both Data Path and Dump Directory are pointing to the new path.
In [SQL Server Configuration Manager] - [SQL Server Agent (MSSQLSERVER)] - [Properties] - [Advanced] Dump Directory is pointing to the new path.
However, the job's History text files are still being written to the old path.
There is no setting in the Jobs or the Maintenance Plans that controls the history file location.
I have searched the registry and changed three settings from the old path to the new path. The registry does NOT contain any more references to the old path.
I rebooted the server, but when the jobs run their history text files are still be written to the old path.
Does anybody have any ideas?? Thanks

I checked the [Job] - [Step] - [Advanced ] - "Output File", and the field is blank.
I then reviewed all the tabs and left menu items in the Job...I cannot find any where the references the old path.
I then went to the Maintenance Plan and checked every thing there. Still cannot find what is referencing this old path.
SQL Server is also still writing xel files to this old path...if that offers any clues.
The text file being generated is the recap of the Job run. Starts with this:
Microsoft(R) Server Maintenance Utility (Unicode) Version 12.0.2430
Report was generated on "xxxxxxxxxxxxxxx".
Maintenance Plan: SQL_Backups_Log
Duration: 00:00:03
Status: Succeeded.
Details:
Thanks for the ideas....

There are marker elements in my FM file,How can I change their text information?

In my Fm file,I want to change the text information of marker,How can I deal with it?

Jack:
Begin by selecting the marker. If you haven't already done so, use View --> Text Symbols to allow you to see the markers.
You can then use your mouse or keyboard to select the marker manually or use
CTRL+f to open the Find/Change tool, in the
Find list choose
Marker of Type and specify the type of marker (or choose
Any Marker if you don't the marker type), then click
Find.
After a marker has been selected, press in sequence
ESC s m to open the
Marker tool, edit the marker text, then click
Edit Marker.
Cheers & hope this helps,
Riley

Changing HTML to text file using java

Hi,
I am doing a project in which i have to read news articles from websites. I have tried XML but for that i need to know which tag has the article in it. Since i have to read from various websites so each site used different tags for different informations.
Is there anyway that i can change an HTML file into a text file using java. Maybe some command that removes all the HTML tags and gives just the information. Is there anything else that anyone would like to recommend?
Thanx
yafis

Maybe something like this:
import java.io.*;
import java.net.*;
import javax.swing.text.*;
import javax.swing.text.html.*;
class GetHTMLText
     public static void main(String[] args)
          throws Exception
          EditorKit kit = new HTMLEditorKit();
          Document doc = kit.createDefaultDocument();
          // The Document class does not yet handle charset's properly.
          doc.putProperty("IgnoreCharsetDirective", Boolean.TRUE);
          // Create a reader on the HTML content.
          Reader rd = getReader(args[0]);
          // Parse the HTML.
          kit.read(rd, doc, 0);
          // The HTML text is now stored in the document
          System.out.println( doc.getText(0, doc.getLength()) );
     // Returns a reader on the HTML data. If 'uri' begins
     // with "http:", it's treated as a URL; otherwise,
     // it's assumed to be a local filename.
     static Reader getReader(String uri)
          throws IOException
          // Retrieve from Internet.
          if (uri.startsWith("http:"))
               URLConnection conn = new URL(uri).openConnection();
               return new InputStreamReader(conn.getInputStream());
          // Retrieve from file.
          else
               return new FileReader(uri);
}

How to change the text in EPS file

You can't if it's been outlined / vectorised.

Select Correct Text File - Names Changing

Eevery few hours my AS400 generates a text file. I am writing a program that will automatically take this file and convert it to an XML. The problem I am having is with the naming convention of the text file:
"IR + 6 digit number which increments by one each time a file is generated + _ + The start date and time for the file +_to_ + end date and time for the file + .txt". For example IR000002_20070528141515_to_20070528170003.txt is the name of the second file generated which started at 14:15:15 on 28/05/2007 and ended at 17:00:03 on 28/05/2007.
Each time my program runs I want it to read the latest file that has been generated. I know where the file will be found and how to select the file when it is generated with the same name each time but havnt a clue now that each file has a different name. Can anybody help? Can I use JFileChooser?

You can use the lastModified() method of the File object to your benefit:
import java.io.File;
public class FindLatestFile {
        public static File getLatest(File thisDir) throws Exception {
                long latestModDate = -1;
                File latestFile = null;
                if (!thisDir.isDirectory()) {
                        throw new Exception("Please pass in a directory.");
                File[] fileList = thisDir.listFiles();
                for (File f : fileList) {
                        if (f.lastModified() > latestModDate) {
                                latestModDate = f.lastModified();
                                latestFile = f;
                return latestFile;
        public static void main(String[] args) {
                try {
                        System.out.println("The latest file in the current directory is " +
                                        getLatest( new File(System.getProperty("user.dir") ) ) + ".");
                } catch (Exception e) {
                        e.printStackTrace();
}
