If the user backs up their device to either iCloud or Mac/PC, they can restore the app data from that backup.
There's no need to do what you intend.

Issue : Read a text file and print the same

Hi, My requirement is to read a text file and print it the same way.
import java.io.BufferedReader;
import java.io.FileReader;
public class CatFile {
public static void main(String[] args) throws Exception
     FileReader file = new FileReader("D:/Test/Allfiles.txt");
     BufferedReader reader = new BufferedReader(file);
     String text = "";
     String line = reader.readLine();
     while (line != null)
          text += line;
          line = reader.readLine();
     System.out.println(text);
The text file i used contains
A
B
C
but my output is ABC.
What change should be made to print it the same way in the txt file ?

Hi EJP,
I modified the code based on your suggestion and now its working as expected. Thanks
Modified code :
import java.io.BufferedReader;
import java.io.FileReader;
public class CatFile {
public static void main(String[] args) throws Exception
     FileReader file = new FileReader("D:/Test/Allfiles.txt");
     BufferedReader reader = new BufferedReader(file);
     String text = "";
     String line = reader.readLine();
     while (line != null)
          System.out.println(line);
          line = reader.readLine();
          text += line;
}

use the StructXML2Plain or XML2Plain from the standard MessageTransformBean
Add the module to you Mail adapter before the mail adapters standard module itself

What I wanna do is to read all the data above and buffer them in a queue for each user( there are only 10 users in total).
I already created a class called Class packet:
public class packet {
    private int timestamp;
    private int user_id;
    private int packet_id;
    private int packet_seqno;
    private int packet_size;
    /** Creates a new instance of packet */
    public packet(int timestamp,int user_id, int packet_id,int packet_seqno, int packet_size)
        this.timestamp = timestamp;
        this.user_id=user_id;
        this.packet_id=packet_id;
        this.packet_seqno=packet_seqno;
        this.packet_size=packet_size;
}then I wanna to create another Class called Class user which I can create a queue for each user (10 users in total) to store type packet information. the queue for each user will be in the order by timestamp.
any idea and sample code will be appreciated.

Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

How to read the contents of a text file and populate the data in a table ?

Hello All,
Can anyone advise on how to acheieve the above ? I am trying to read in a text file (CSV) and have the contents populated to the respective UI elements in a table. Any help is greatly appreciated.
from
Kwok Wei

Hi,
Let us consider you have list of names(Seperated by delimeter) in a text file and you want to display in a table.
1. Create Context Node "Names" and context attribute "Name"
2. Create Table and bind to the above context.
3.Write the following code in the "Init method.
try{
FileReader f =new FileReader("");
BufferedReader r=new BufferedReader(f);
String names=r.readLine();
Vector Names=new Vector();
// Use Tokenizer and store all the names i a vector//
for(int i=0;i<Names.size();i++){
IPrivate<<VieName>>.INameElement ele=wdContext.createNameElement();
ele.set<<Name>>( Names.get(i).toString());
wdContext.NodeName().addElement(ele);

Reading from a text file and displaying the contents with in a frame

Hi All,
I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
pcode1,pname1,price1,sname1,
pcode2,pname2,price2,sname1,
I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
void ReadTextFile()
                    FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                     InputStreamReader isr=new InputStreamReader(fis);
                     char[] buf=new char[1024];
                     isr.read(buf,0,1024);
                     fstr=new String(buf);
                     String Tokenizer st=new StringTokenizer(fstr,",");
                     while(st.hasMoreTokens())
                                      pcode1=st.nextToken();
                           pname1=st.nextToken();
          price1=st.nextToken();
                          sname1=st.nextToken();
     } //close of while loop
                } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
Thanks in advance.

If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:
MyClassName.pcode1;
MyClassName.pname1;
MyClassName.price1;
MyClassName.sname1

Any way to embed a text file and retain the link?

Hi everyone,
I am embedding the contents of a text file using "Insert > Choose...". This works wonderfully, but it appears to just insert the contents and gives me no way to update the text if the original text file changes. In Word, I can insert the text file and have it retain the link, then I have the ability to update the field (or all files in the document) with updated wording from my source files.
In case you're wondering, I'm exploring using Pages for authoring the user guides for my company's software. We include command usage statements in our documentation and we have a workflow that runs each command, capturing it's help output into a text file, then we include this in the user guide document. Obviously, having the ability to update the user guide document with updated usage syntax is a required piece of functionality. I would like to use Pages instead of Word, but I'm not sure it can do this.
Thanks in advance!
Brian

No, Pages can't do it. It doesn't keep a link to the original text document. You have to replace the text when you have made changes.

Searching a text file and printing the line if found!

Hi, Im fairly new to JAVA and have been googling this for hours and havent found any results that
have helped me...
Im looking to search a text file for a value that is in a that is delimited by colons
eg 45787 : 398948 : 398884 : 398984
IF that value is found I need to print this entire line and move it into a string.
I can work out the delimit part, the problem for me is a)searching the text file
and b) tell java to print that line only??
Any help would be very very much appreciated
Cheers
James

public void printCourses() throws Exception

               int i=0;
               boolean found = false;
               while(sc.hasNextLine())
               //Delimit this line with scanner
               Scanner sc1 = new Scanner(sc.nextLine());
               sc1.useDelimiter(":");
               courseObjArray[i] = new stuinput(sc1.next(),sc1.next());
               i++;
               }//while
               for(int i1 = 0;i1 < courseObjArray.length;i1++)
               System.out.println(courseObjArray[i1].courseCode);
               System.out.println(courseObjArray[i1].courseName);
               System.out.println(courseObjArray[i1].courseName);
               System.out.println("-----------------");
               String courseCode2 = "courseObjArray[i1].courseCode";
               if (courseCode2 == "12345")
                    System.out.println("working");
               else{System.out.println("Not Found");}
       }hmmm just wondering why could this method always return a "Not Found"....if the text file had a whole bunch of values like this
12345:Course1
12344:Course2
12343:Course3
isnt it surposed to return 1 "Working"?? because there is a 12345 in on of the line, in the semi colon delimited line with 2 values, one being the course code, one being the course name??
Given that there is 10 lines (from Array Object)

I want to open a text file and display it within Lookout 5.0

How do you read and display a text file within Lookout 5.0?

Hi Kenneth,
This should have been trivial, but isn't. Well, it isn't that difficult either. Here's the trick:
Create a DataSocket Object. For the URL, type: file:c:\ni\lookout5\test.txt[text]
Leave the Update mode as Automatic for now. Connect a Switch to the Connect member of the DataSocket object.
On the panel, drag-and-drop the DataSocket.data.txt. Toggle the Switch and voila you have the text in Lookout! I have attached an example (detach the txt file to your C drive; or change the path in the DataSocket object).
For the curious, DataSocket is a NI networking technology which supports ftp, http, file, and other protocols. See this
>FAQ f
or general info' on DataSockets.
Hope this helps,
Khalid

How do I export to text file and suppress the cr-lf at end of row?

Hello.
I have created a report that is mean to export to a text file. It will always be a 1 row report and it's always going to be uploaded to a vendor via their website. They don't want the cr-lf at the end of the row.
I can't figure out how to get crystal to not do that. When I export to a text file (not a tab delimited text file), it seems to throw in the cr-lf at the end of the row. I have to manually remove it before uploading it. This task of uploading the file will go to someone else in the near future and I would like to not have to rely on them to do it.
Am I missing it?

Could you please elaborate what do you mean by 'cr-lf'. Just came across these SAP notes,however don't know whether they are applicable in your context.

How to merge text files and put the result in a text file.

Hi,
I am trying to merge the files(text) using OWB and I would like to put the result in a file. Could any one please explain how to do this.
Thanks and regards
Gowtham Sen.

using the unix commnad 'cat' along with the redirect '>>' will concat the files into one target
#this will create the target file and over-write it if it existed already
cat file1 > target
##Now add the rest of the files to the target, without over-writing
cat file2 >>target
cat file3 >>target
cat file16 >> target
You can then use an external table on the target file.
A nicer way would be to user a 'for loop', but this will work fine.

Get-Content c:\output-Copy.txt | Where-Object {$_ -notmatch 'something1', 'something2', 'something3', 'something4' } | Set-Content temp.txt
Above is the program that when it has 1 argument in the -notmatch part will find the specific string and delete the entire line. I need to be able to use multiple strings for my search, I am totally drawing a blank on this and I know its something REALLY
simple but my brain is fried. The above code will work IF i only leave 'something1' and delete the rest. I need to find MULTIPLE matches and remove them all at once, what is a good way to accomplish this.

You can use an alternating regex, like this:
Get-Content c:\output-Copy.txt |
Where-Object {$_ -notmatch 'something1|something2|something3|something4' } |
Set-Content temp.txt
[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Want to update a text file and reflect the same on iview immediately
