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

There are so many things wrong with this VI, I'm not even sure where to start.
Hard-coding paths that point to your user folder on the block diagram. What if somebody else tries to run it? They'll get an error. What if somebody tries to run this on Windows 7? They'll get an error. What if somebody tries to run this on a Mac or Linux? They'll get an error.
Not using Read From Spreadsheet File.
Use of local variables to populate an array.
Cannot insert values into an empty array.
What if there's a line missing from the text file? Now your data will not line up. Your case structure does handle this.
Also, how does this answer the poster's question?

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

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.

*Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

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.

Include text file and display from text file

Ok. I'm found the site with the monkey on the the flash thing and all it shows is a name, email and something else and I used it and it works by including a txt file and displaying text from that file as putting down this information
name.text = this.name;
and I can't find the site anymore to get help.
I want to know how to include a PHP script that shows this information like this
text=something I need&username=My Name&email=[email protected]
I want to show this stuff on the flash but every time I execute by using it as localhost/test.php, it will show a sentax error.
This is really stressing me out and I need a lot of help on this stuff.
Can someone help me?

ok. let me describe something else.
there's 3 text boxes that is dynamic text.
one of them is called name
the other one is called email
and last one is called location
in the text file, it shows this for importing to the flash file
name=My Name&email=EMAIL&location=My Location
When viewing the flash file that you created, it shows the name, it shows the email, and it shows location.
When I do it on my own even with a text file, it keeps on saying that there is an error on line 1.
I found a site that shows how to do it and it shows what to put in a text file, and it shows the action script. On the FLA file that he shows me has a monkey on the flash file and it has 3 text boxes that I described above. As well as the text file, it is the same. I used the example and it worked but I can't find the example again. I don't know what happened to the website and I don't know what happened to the download I had but it is not downloaded any more. I have adanced systemcare pro so it clears out my recent web searches and my recent downloads so I can't find it. I did a google search on anything about action scripts. I even did a monkey action script search and I couldn't find it.
It's making me mad and I don't know what to do. This is stressing me out way more than you think.
UPDATE:
I did a google search on a file I found in my www folder and I found it. finally.
Here's the site.
http://www.kirupa.com/developer/mx/externaldata.htm
now, I need to figure out how to load it from a PHP file.

I want to open a txt file and output data through an AO-using DAQmx for PXI

I have a PXI running a 8145RT CPU. I have a PX6040E Multifunction DAQ card installed in the PXI. I want to program an application where I open a txt file (existing in one of the the RT machines' folders), read the first row, and output its data through an AO channel. The drivers I should use is DAQmx v7.1, and the Labview RT v.7
Any idea?

What exactly are you having problems with? Reading a text file can be done a number of ways. Look at the File I/O palette and check out Read Lines From File or Read Characters From File. There are string to number conversion functions on the string palette (i.e. Scan From String). There are also numberous shipping examples on using DAQmx for analog out. If you have a specific problem or question, please post back with additional details.

Open a text file and show it in JList

hi!
Can somebody give me a example!!
Tnx

public class FileChooser extends JFileChooser
protected FileStreams fileStreams;
public FileChooser()
//Set Text Filter
setFileFilter(new TextFilter());
//Show Files
int result = showOpenDialog(this);
//Grab Selected file
if (result == JFileChooser.APPROVE_OPTION)
getSelectedFile();
System.out.println("File:" + getSelectedFile).getPath());
if (getSelectedFile() != null)
try
fileStreams = new FileStreams(getSelectedFile());
catch (Exception e)
System.err.println("Error:FileChooser:Stream:" + e);
if (result == JFileChooser.CANCEL_OPTION){System.exit(0); }
}//End Class
You would need to create a class such as fileStreams that would take in:
BufferedReader buffReader = new BufferedReader(new FileReader(file));
and then do something.

Hi Maruti,
just open the file and loop on the rows, here an example::
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
FileReader f = new FileReader("c:
FileName.ext");
while ((s = in.readLine()) != null)
//Here you can put the line into a WD context structure, i.e:
wdContext.currentContoEconomicoFormElement().setField(s);
}catch (Exception e) {.....}

How to open a Excel file and display on the custom screen

Guys, I am new to screen programming. In my first screen (SCREEN #9000) I want to put a field, where I must be able to select a file from my desktop and when I click the DISPLAY button, it should suck all the data from the spread sheet in to an internal table, and should display the next screen (SCREEN #9001), displaying the data from the internal table along with a button called LOAD. Now when I click the LOAD button after reviewing the data, it must load the data to my custom table in R/3. I know how to load an Excel spreadsheet to R/3 without the custom screens. But my requirement now is to do from custom screens like I mentioned above. Any ideas how to do this? Thanks.
Dan

Hi Dan,
In my first screen (SCREEN #9000) I want to put a field, where I must be able to select a file from my desktop and when I click the DISPLAY button, it should suck all the data from the spread sheet in to an internal table, and should display the next screen (SCREEN #9001)
For this create a MPP program and create a Push button. Write the code for this to open a file like use f4_filename.From here you are able to select a file.
+ displaying the data from the internal table along with a button called LOAD. Now when I click the LOAD button after reviewing the data, it must load the data to my custom table in R/3.+
With the above you are able to open a file and now you have to load that data into internal table. Select the file from the desktop.
Totally you have to create 1) Screen 2) Push button( Open File) 3) Load data ( From file) .

Importing a text file and displaying it

Ok, my goal is to import a text file which i have done. I want to import it into a 2D array. There are 26 rows and 2 columns. Basically just a translator program. This is what i have to load the text file into java. But i am having trouble displaying the array with the data loaded into it. any ideas?
public static void loadData(String a[][])
     throws java.io.IOException
     String file = "C:\\print.txt";
     String inLine;
     int row;
     FileReader fr = new FileReader(file);
     BufferedReader br = new BufferedReader(fr);
     for (row = 0; row<=26;row++)
          a[row][0] = br.readLine();
          a[row][1] = br.readLine();
     br.close();
     System.out.println(a[row][0]);
     }

my goal for this program is to have a user enter a phrase to be translated. I have the text file that i am loading into java that has the english word and then the translated word. I want to load that into the 2D array and display it. Then use a stringtokenizer for the translate part. But the problem i have right now is trying to display the data that was loaded into the array. any ideas?

Read a text file and display a xy graph

Hi!
I am using LabVIEW 8.5, and I am trying to read columns from
a file and plot with xy graph. I can do it with two channels, but I am having
problems when the numbers of channels connected increase (maybe six or ten).
My text file looks like this:
[Where first column x = time, the rest of the columns are
channels = y]
8.828        22.604        23.076            [The number of channels connected can
change]
9.828        22.604        22.604
10.828      21.658        22.131
11.828      22.131        22.131

Thanks for the advice!... I just modified what I had a
little bit and it is working, maybe is not the optimums solution…
I would like to make the time invisible in the graph… It that possible? I attached a picture of my graph, because my English is not good. There are two lines near to 22 (two channels
connected at that moment), and a line near to 0 which is time (the strong pink one). I would like to make invisible the strong
prink one only. I try to make invisible,
but I fail… I changed colors looking for another solution and I fail again,
because it is taking the colors that I choose for the channels. I can not disable because I need it to make
the x axes works with the time that I already saved.
If someone has an advice or suggestion I really appreciate it…
Sincerely,

Reading text file and display in the selectOnechoice list item In ADF.

Hi,
I have a requirement to read the text field which have list of strings and that string display in the SelectOneChoice List item component on page load.
I am using Jdeveloper 11.1.2.3 version.
Any suggestion will highly appreciated..
Thanks in advance.

Hi,
Google will produce you with hints on how to read content of a file from Java (ideally the file uses some delimiter). Then in a managed bean, you read the file and save its content in a list of SelectItem. So your managed bean should have the following property and setter/getter pairs
ArrayList<SelectItem> listFromFile = new ArrayList<SelectItem>();
public void setListFromFile(ArrayList l){ //you don't need this }
public ArrayList<SelectItem> getListFromFile(){
   //read file content and iterate over the file list entries
for(i=0, i < fileContent.length, ++i){
     SelectItem si = new SelectItem();
     si.setValue(... the value to update the list of value with ...);
     si.setLabel("... the label to show in the list ...");
     listFromFile.add(si);
return listFromFile;
}The af:selectOneChoice component should look as follows
<af:selectOneChoice id=".." value="...attribute to update with selection ..." ...>
   <f:selectItems value="#{managedBean.listFromFile}"/>
</af:selectOneChoice>Frank
