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?

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.

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 -

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? -
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.

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.

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.
RegardsHi,
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 -
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

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
12.828 22.131 22.131
13.828 22.604 22.604
14.828 21.658 22.604
15.828 22.131 22.131
16.828 21.658 23.076
17.828 22.604 22.131
18.828 22.131 22.604
I attached a picture of what I already try… Now I am trying
a combination of those. If anyone has some
advice or suggestion, please let me know.
Sincerely,
Julieta.

xygraph.PNG 25 KBThanks 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,
Julieta.

Powershell script for pinging computers from a text file and displaying output with ip address
i am currently using the following script to display the computers that are pinging, i also want the script to display the
ipaddress along with the results but the results are displayed not properly, i want the result to be displayed in a table or list format, what am i missing?
$ServerName = Get-Content "C:\scripts\computers.txt"
foreach ($Server in $ServerName) {
if (test-Connection -ComputerName $Server -Count 2 -Quiet) {
"$Server is Pinging "
} else
{"$Server not pinging"
foreach ($server in $servername) {
Get-WmiObject -class "Win32_NetworkAdapterConfiguration"|Select-Object IPAddress|Format-ListNot sure I completely understand your question but looking at the code you posted I see one fairly simple change that may be what you are missing...your Get-WMIObject statement never passes a server name to the command. You loop through the list
you obtained but never actually pass that to anything. So the simple change would be to just do the following...
foreach($server in $servername)
Get-WMIObject -class win32_NetworkAdapterConfiguration -computername $server
| select IPAddress | FT -auto
you could also tuck that command into the previous foreach/if/else statement and just do each one that actually responds. -

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.

I'm creating an epk and I need to add a bio to the menu. Can I import the text file or do I need to retype the bio somewhere? What is the best way to proceed?
Electronic Press Kit.
Usually in the form of video outtakes, movie trailers, cast and crew interviews. Basically, the stuff that gets bunged onto commercial DVDs as extras or ends up on late night TV "Making Of..." shows.
To answer the OP, you want a button on the menu that leads to a still image, or series of them, set up as a slide show. You can copy/paste the text in DVD Studio and then add formatting via the Text menu. (Highlight the text and right click to access formatting controls). Or do it in a graphics application using the appropriate video image preset. -
I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?
Attachments:
try2.txt 2 KB
read_array.vi 21 KBThe problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.
