Text files and audio capture

Hello everyone!
I have a problem on a fairly complex VI and I'm not an expert.
In the main loop I have a capture of strings via serial port, I analyze some numeric values from these strings and when these values exceed the predefined I generate "alarms" with LED.
The point is that, once turned on the alarm, I have to save two files: the text string from the serial and the registration of 2-3 seconds of audio. These files must have the name taken from the "get date / time".
How can I do?
I tried to do three different loops at the same time:
1. Main
2. Text saving
3. Audio recording.
But unfortunately I can not exchange information on the file name and string read between the various loops, even though the "local variable".
Can anyone help me?
Thanks!!!

That doesn't usually help. It just irritates people when you post the same question in multiple places. Plus, it leads people to ask you the same exact questions or give you the same exact suggestions when they don't know you've already asked the question somewhere else and are already being helped.
As for your code... you have a classic race condition. Actually more than one. You are reading the "appended path" via the local variable before it's actually been written to. The value is set inside the loop, but your program will read the value before either loop has even started.Your second race condition has to do with the Stringa local variable. Again, you are reading its value without actually knowing if it's been updated by the other loop.
Why do you have 2 loops? Why isn't the writing of the file in the same loop as the read operation?
Other comments:
Why are you creating the filename inside the loop? That makes no sense. Why would you want to create a new file each and every time you loop around?
There is a simpler way to create the filename: If you look at the help for the Format Into String function you will see that you can use format codes to convert the timestamp to a string:

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.

Please help! I defragged my hard drive and now Illustrator CS6 is trying to open all of my complex Illustrator files with a "Text Import Options" box as if they are text files, and they are not opening!

Please help! Illustrator CS6 started trying to open all of my complex.ai files with a "Text Import Options" box as if they were text files, and they are not opening! Help!

Hi Monika,
I have spent the last two or three days trying to do what you suggested. I uninstalled Adobe 6 from Windows. Some files that CS6 placed on my system during installation remained, including fonts and .dll files.
I had to abandon the Cleaner Tool you suggested because in one screen it allowed me to specify removing CS6 only, but on the following screen it only gave on option to remove ALL Adobe programs. I could not do that because I didn't have the serial number handy for CS3 in case I want to reinstall it at some point.
I tried to get technical help with the Cleaner Tool problem but no definitive help was available, so I reinstalled CS6 again without having the benefit of the Cleaner Tool. I tried to get the serial number for CS3 so I could use the Cleaner Tool but spent 2 wasted hours in chat. Even though I had a customer number, order number, order date, place of purchase, the email address used AND 16 digits of the serial number, in two hours the agent couldn't give me the serial number. After two hours I had nothing but instructions to wait another 20 minutes for a case number.
Illustrator CS6 is still trying to open some backups as Text and otherNone of the problems have been fixed. I have tried to open/use the .ai files in CS6 installed on another system and am getting the same result, so I don't think the software was damaged by the cleaner. The hard drive cleaner is well-known and I've run it many times without any problem to previous versions of Illustrator or any other programs.
When I ordered, the sale rep promised good technical support and gave me an 800 number, but after I paid the $2000, I learned that the 800 number she gave me doesn't support CS6 and hangs up on me. Adobe doesn't call it a current product even though they just sold it to me about 3 weeks ago.
Would appreciate any help you experts can offer. If I can't solve this, the last backup I can use was from June and I will have lost HUNDREDS of hours of work and assets that I cannot replace.
Exhausted and still desperately in need of help...

Show us how you've read the data and what you've tried to do to parse it. Once you've got the last rows, you can loop over them using Spreadsheet String to Array (after cleaning up a few messy spaces).

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("");

I need to read data from a text file and display it in a datagrid.how can this be done..please help

hey ppl
i have a datagrid in my form.i need to read input(fields..sort of a database) from a text file and display its contents in the datagrid.
how can this be done.. and also after every few seconds reading event should be re executed.. and that the contents of the datagrid will keep changing as per the changes in the file...
please help as this is urgent and important.. if possible please provide me with an example code as i am completely new to flex...
thanks.....

It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.
[http://java.sun.com/docs/books/tutorial/essential/io/]
*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

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.

Sorry I'm just beginning coding and I'm still a noob. Any help is appreciated. Thank you!

Ok, so if I'm following this correctly you should be able to just loop through all of the files in that folder whose file name matches the pattern and then read the first 22 lines, recording only the first and the last.
Exactly how you store the animal data probably depends on how you are going to display it and what else you are going to do with it. Is there anything other than name and cage number that should be associated with each animal?
You might want to make a dataset with a datatable to describe the animal, or you might write a class, or you might just use something generic like a Tuple. Here's a simple class example:
Public Class Animal
Public Property Name As String
Public Property Cage As String
Public Overrides Function ToString() As String
Return String.Format("{0} - {1}", Name, Cage)
End Function
End Class
With that you can use a routine like the following to loop through all of the files and read each one:
Dim animals As New List(Of Animal)
Dim folderPath As String = "E:\Furry Friends Animal Shelter Solution\Furry Friends Animal Shelter\"
For Each filePath As String In System.IO.Directory.GetFiles(folderPath, "Report Q?.txt")
Using reader As New System.IO.StreamReader(filePath)
Dim lineIndex As Integer = 0
Dim currentAnimal As New Animal
While Not reader.EndOfStream
Dim line As String = reader.ReadLine
If lineIndex = 0 Then
currentAnimal.Name = line
ElseIf lineIndex = 22 Then
currentAnimal.Cage = line
Exit While
End If
lineIndex += 1
End While
animals.Add(currentAnimal)
End Using
Next
'do something to display the animals list
Then you might bind the animals list to a ListBox, or loop through the list and populate a ListView. If you decided to fill a datatable instead of making Animal instances, then you might bind the resulting table to a DataGridView.
There are lots of options depending on what you want and what all you need to do.

Take an existing text file and modify values

I’m looking to take an existing text file and modify certain values inside of it. Then save it to a new file, with all the same formatting as the original. The file format is not uniform and can change.
Basically the file is:
Random numbers and letters of unknown length for an unknown number of lines.
Label="Test_#"
Description
String
X=123
Y=456
Z=-789
20 lines of strings with numbers in them
Label="Test_#2"
Description
String
X=-1232
Y=4562
Z=7892
Then it repeats a set number of times.
I want to modify the X Y and Z = values for each Test_#.
I’ve managed to import the important values into a numeric array and I have a different array with values that will replace the existing ones. I’m having troubles replacing the existing ones. There are no zeros before or after the existing numbers so they are all different lengths.
If anyone has any sample code that does anything similar please post it. I’m sure someone has done something like this in the past.
Solved!

I just thought I would throw this out there. Can you make the .txt file tokenized? This would make searching for specific parameters much easier.

See in this case as you are dealing with Files and database. you need read the File by using the I/O Streams. if you have to select some particular values you can go Random access file.Once you have retrived values. You can go for the second part that is make a jdbc connection to database, and use simple SQL statements to populate those values into the table.
How this will give you a better picture

Where does this java program read a text file and how does it output the re

someone sent this to me. its a generic translator where it reads a hashmap text file which has the replacement vocabulary etc... and then reads another text file that has what you want translated and then outputs translation. what i don't understand is where i need to plugin the name of the text files and what is the very first line of code?

does it prompt me to give it a text file name?Apparently.
when i run it this is all i get:

Press any key to continue...Right. And "wordmapfile" is almost certainly supposed to be a file that holds the word map, and "textfile" is almost certainly the file of text that it's going to translate.

     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;
}

Read multiple text files and sort them

I am trying to read multiple text files and store the data from the file in vector.
but for days. I am with no luck. anyone can help me out with it? any idea of how to sort them will be appreciated.
Below is part of the code I implemented.
public class packet {
    private int timestamp;
    private int user_id;
    private int packet_id;
    private int packet_seqno;
    private int packet_size;
    public packet(int timestamp0,int user_id0, int packet_id0,int packet_seqno0, int packet_size0)
        timestamp = timestamp0;
        user_id=user_id0;
        packet_id=packet_id0;
        packet_seqno=packet_seqno0;
        packet_size=packet_size0;
    public void setTime(int atimestamp)
        this.timestamp=atimestamp;
    public void setUserid(int auserid)
        this.user_id=auserid;
    public void setPacketid(int apacketid)
        this.packet_id=apacketid;
    public void setPacketseqno(int apacketseqno)
        this.packet_seqno=apacketseqno;
    public void setPacketsize(int apacketsize)
        this.packet_size=apacketsize;
    public String toString()
        return timestamp+"\t"+user_id+"\t"+packet_id+"\t"+packet_seqno+"\t"+packet_size+"\t";
}Here is the data from part of the text files. ( the first column is timestamp, second is userid, third is packetid.....)
0 1 1 1 512
1 2 1 2 512
2 3 1 3 512
3 4 1 4 512
4 5 1 5 512
5 6 1 6 512
6 7 1 7 512
7 8 1 8 512
8 9 1 9 512
9 10 1 10 512
10 1 2 11 512
11 2 2 12 512
12 3 2 13 512
13 4 2 14 512
14 5 2 15 512
15 6 2 16 512
16 7 2 17 512

Here's a standard idiom for object-list-sorting:

0 1 1 1 512
1 2 1 2 512

7 8 1 8 512
8 9 1 9 512
9 10 1 10 512

11 2 2 12 512
12 3 2 13 512
