Trying to read the text file via Flex FileStream.
Hello,
I am following the Flex Help and trying to read a text file.
I have created project called test, and within test.mxml, I have
created the <mx:script> tags and within I am pasting this
code yet I get errors:
What am I doing wrong? Please help.
Please see the code:
You cannot do all that complex assignment work outside of a
function. Because of the way components are generated/compiled, the
declared vars do not exist when called.
Declare the vars in instance scope, but use an init()
function to do the assignments.

How can i read the text files and buffer the data in Vector?
hi. I have been running into this problem for days, but with no luck and losing right direction.
The problem is : I am trying to read a text file and buffer the data into a
Queue for each user.
the sample text file is as below:( 1st column is timestamp, 2nd is user_id, 3rd is packet_id, 4th is packet_seqno, 5th is packet_size)

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. -
Hi All,
powershell script Method required to read a value from registry and then taking the backup of that values in some text file.
For example the hive is

Also how to read the text file values so that we can again write to registry hive back from the back up text file.

How to make an applet to read the Text file present inside a jar
Hi All,
I have writen one applet named ReadFile.java which reads a text file present in the same directory and does some manipulation of text file contents.
The applet code runs successfully when i run the applet in command prompt like
{color:#ff0000}*java ReadFile*{color}
And i am getting the needed results.
Then i made a jar file with the applet code and text file as
{color:#ff0000}*jar cvf rf.jar ReadFile.class File1.txt*{color}
Then i have inlcuded this applet inside a html file as
{color:#ff0000}*<applet code= "ReadFile.class" width= "500" height= "300" archive = "rf.jar" ></applet>*{color}
after this when i load the html file, the applet code is not executed fully. Its throwing FileNotFoundException: File1.txt.
Applet is not recognizing trhe text file present inside the jar file.
Can any body explain me how to overcome this problem. Any setting needs to be done for making the applet indicate the presence of Text file inside the jar file.what code in your applet gets the text file and reads it? are you using getResource or something similar?

How to Read the "text file and csv file" through powershell Scripts
Hi All
i need to add a multiple users in a particular Group through powershell Script how to read the text and CSV files in powershell
am completly new to Powershell scripts any one pls respond ASAP.with step by step process pls
Regards:
Rajeshreddy.kHi Rajeshreddy.k,
To add multiple users to one group, I wouldn't use a .csv file since the only value you need from a list is the users to be added.
To start create a list of users that should be added to the group, import this list in a variable called $users, the group distinguishedName in a variable called $Group and simply call the ActiveDirectory cmdlet Add-GroupMember.
$Users = Get-Content -Path 'C:\ListOfUsernames.txt'
$Group = 'CN=MyGroup,OU=MyOrg,DC=domain,DC=lcl'
Add-ADGroupMember -Identity $Group -Members $Users -

I do not know how to achive such funcionality.
looking forward for your help in this regard. Please have a look on the code as pasted below:

DLL is failing to read the text file on RTOS
I have created a DLL using Fortran Microsoft Power STation 4.0. The DLL reads data from text files. A vi is created to call this dll. This vi is working fine in winodows. It is reading from the text files and manipulates.
When this vi is donwloaded to RTOS Labview 7.1, it fails to read the file and the RT reboots. The error message is "file not found (filename)". The file is present is the current directory of DLL.
Please assist me in solving this problem. My email Id is: [email protected] or [email protected]Hello GTRE,
It seems like something isn't letting you access that DLL. Do you have the DLL moved onto the RT target? What is your real-time target? Does the DLL require access to other resources? What specifically does the error message say? Does it contain an error code?
Answering these questions will allow us to narrow down the problem - thanks!

WebLogic writes to a text file and an applet reads the text file
Hi there,
I need some help here!
I have an applet that needs to read from a text file:
final URL prtDataURL = new URL("http://" + getCodeBase().getHost() + ":" + getCodeBase().getPort() + "/ESTC/lib/prtDataFile.txt");
final URLConnection urlConn = prtDataURL.openConnection();
urlConn.setUseCaches(false);
urlConn.setDoInput(true);
urlConn.setDoOutput(false);
final InputStreamReader is = new InputStreamReader(urlConn.getInputStream());
final BufferedReader in = new BufferedReader(is);
String inputLine;
while ((inputLine = in.readLine()) != null){
String[] tmp = inputLine.split("§");
this.dateTime = tmp[0];
this.quanTot = Integer.parseInt(tmp[1]);
this.quanSco = Integer.parseInt(tmp[2]);
this.quanSef = Integer.parseInt(tmp[3]);
this.valTot = Double.parseDouble(tmp[4]);
this.valSco = Double.parseDouble(tmp[5]);
this.valSef = Double.parseDouble(tmp[6]);
in.close();
is.close();and this is ok.
Now I have the web server (WebLogic) that must write, at regular time intervals, to that file (prtDataFile.txt). The web application writes to the file (which belongs to the application).
I've tried open the file with the File object but since the war file is unexploded I can't get the real path!
I've tried open an url connection,
final URL url = new URL("http://10.191.33.249:16801/ESTC/lib/prtDataFile.txt");
final URLConnection connection = url.openConnection();
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setDoInput(false);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(currentDate + "§" + quantTot + "§" + quantSco + "§" + quantSef + "§" + valTot + "§" + valSco + "§" + valSef);;
out.flush();
out.close();which seems a little stupid since I'm opening an URLConnection to the same place where the application is. Anyway it doesn't work, i.e., it doesn't write to the file but it doesn't gives me any errors or exceptions.
Is there another way to get this two pieces communicating?
Thanks in advanceI have almost the exact same problem, and I am in the same situation as you are with respects to the language.
I am simply trying to create a file and output some garbage to it but my applet always spits back a security violation. I've tried eliminating the restrictions on the applet runner I use but I still get the error.
My method:
debug = new Label() ;
debug.setLocation( 20, 20 ) ;
debug.setSize( 500, 15 ) ;
add( debug ) ;
// output
try
OutputStream file = new FileOutputStream( new File( "" + getCodeBase() + "output.txt" ) ) ;
byte[] buffer = { 1, 2, 3, 4, 5 } ;
file.write( buffer ) ;
file.close() ;
} catch( Exception e )
debug.setText( e.toString() ) ;
Can anyone tell why this isnt working? -

Read a text file before knowing the encoding
Hi,
I've wrote a AppleScript to adjust time delay of *.lrc file(txt file but different extension).I only got a messed up text, in other aspect, it works well. I understand applescript read the text file using the wrong encoding, but I can't just set the encoding to UTF-8, for it can be UTF-8 and it can be Shift-JIS, Big5 andGB18030 as well. I don't know how to open text without getting messed up and write the result to a new text file on desktop using UTF-8 encoding. Can anyone help me with this? Thanks in advance.
Code:
on run
set _lrcFile to (choose file)'s POSIX path
display dialog "Time to delay (sec):" with title "Adjust LRC Delay" default answer "-0.5"
set _timeDelay to text returned of result
try
set _timeDelay to _timeDelay as real
on error
display dialog "Input must be a real" with title "Error" buttons {"Stop"} default button "Stop"
error number -128
end try
set _paraList to paragraphs of (read POSIX file _lrcFile)-->I don't know how to read text file properly here.
set _newLrc to ""
repeat with _para in _paraList
set _timecode to do shell script "sed 's/\\[\\([0-9]\\{2\\}\\):\\([0-9]\\{2\\}.[0-9]\\{2\\}\\)\\]\\(.*\\)/\\1 \\2/'<<<" & quoted form of _para
if _timecode as string is not (contents of _para) then
set _timecode to words of _timecode
set _min to (item 1 of _timecode) as integer
set _sec to (item 2 of _timecode) as real
set _sec to _sec + _timeDelay
set _min to _min + _sec div 60
set _sec to _sec mod 60
set _sec to (round (_sec * 100)) / 100
if _min < 10 then
set _min to "0" & _min as string
else
set _min to _min as string
end if
if _sec < 0 then
set _sec to "00.00"
else if _sec < 10 then
set _sec to "0" & _sec as string
else
set _sec to _sec as string
end if
if (count of _sec) < 5 then
set _sec to _sec & "0"
end if
set _lyrics to do shell script "sed 's/\\[\\([0-9]\\{2\\}\\):\\([0-9]\\{2\\}.[0-9]\\{2\\}\\)\\]\\(.*\\)/\\3/'<<<" & quoted form of _para
set _newLrc to _newLrc & "[" & _min & ":" & _sec & "]" & _lyrics & return
else
set _newLrc to _newLrc & contents of _para & return
end if
end repeat
-->write _newLrc to destop here (using UTF-8 encoding)
end run
Sample of *.lrc and the result after delaying 0.5s.Hope this post will help people doing their homeworks...

i've trying to send a text file via rs-232 but no success
The file contains a code for a device im dealing with, when i send the text file with labview to the device, it went ok with no errors, but when i connect the device on hyperterminal and check if the code was loaded it was not.
can you please give some clues to deal with this?
thanks a lot

DefineHome.txt 1 KBSome devices are very picky with the End Of Line. You might want to right-click on your FIle Read and deselect the "Convert EOL".
Or if you need to write 1 line at a time, right click on the Read Text File and select "Read Lines". Set the number of line to read to -1 (read all) and then wire the resulting array into a FOR loop where you do the VISA Write.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Error 7 occurred when trying to read a spreadsheet file in LabVIEW
Hi,
I got the message (in bold) below when I was trying to read a text file type. I also include a snippet of my block diagram.
Error 7 occurred at Open File+.vipen File
Possible reason(s):
LabVIEW: File not found. The file might have been moved or deleted, or
the file path might be incorrectly formatted for the operating system.
For example, use \ as path separators on Windows, : on Mac OS X, and /
on Linux. Verify that the path is correct using the command prompt or
file explorer.
I really appreciate if someone can help me. Thanks.

read from spreadsheet.png 70 KBHi Ravens Fan,
Thanks again for your valuable input. I replaced the string manipulation functions with a path control. I think it works coz I can see the waveform data, rms values etc. And then you said if it works, do a Path to String on that...and I'm not exactly sure how to do that. I attached a snippet of the modified vi. you may refer the original vi snippet in my previous email.
I appreciate it if you could help me again.
Thanks.

Please help me in reading the ascii file in encoded format
hi ,
iam trying to read the ascii file and i need to encode the text file, can u suggest me what arre the different methods are availble for me to encode the text file, please suggest me which is the effiecient method tto use?This question has been answered before, please search the forums in future.
You could do something like this, it probably not the most efficient though.
If you don't need to do it in code then the native2ascii does this conversion see: http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/native2ascii.html
public static void convert(String vsFile) throws IOException
File f = new File(vsFile);
FileReader fr = new FileReader(f);
char[] buf;
int bytesRead = 0;
int startAt = 0;
String content = "";
do
buf = new char[512];
bytesRead = fr.read(buf, 0, 512);
startAt += bytesRead;
String tmp = new String(buf);
content += tmp;
while (bytesRead == 512);
FileOutputStream fout = new FileOutputStream(f);
OutputStreamWriter out = new OutputStreamWriter(fout, "UTF-8");
out.write(content.trim());
out.flush();
out.close();

Reading a text file from a URL
I am having problems trying to read a text file from a URL.
This is the code i have been using:
package Java;
import java.net.*;
import java.io.*;
public class Main_1 {
public static void main(String[] args) throws Exception {
URL myAddress = new URL("http://www.geocities.com/simonrobinson1/java/farrago.txt");
BufferedReader in = new BufferedReader(
new InputStreamReader(
myAddress.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
but it returns an error saying:
java.net.NoRouteToHostException: Operation timed out: no further information
at java.net.PlainSocketImpl.socketConnect(Native Method) .....etc etc.
Is this just a problem due to my network or is there something wrong with my code ????Altho you can access the file by typing the URL in a browser, geocities being a free web-hosting service don't like you to access the materials without seeing their ads. You have to find a way to trick it into thinking that you are indeed coming in from a web browser even tho you aren't.
