Problem Reading In a 5MB File...help plz..

Im attempting to read in a 5Mb file, but it takes forever to read in, plus it only seems to able to read in 23189 lines before it hangs. This may be due to my implementation as each new line that i read in i append to a String... any hints as to how i'm meant to read in a large file in order to eventually display it in a JTextComponent.
The method used to read in the file is below:
public void readinBigFile() {
     String temp = "";
     try {
          BufferedReader in = new BufferedReader(new FileReader("dnd/BigFile"));
          int count = 0;
          while (in.readLine() != null) {
               count++;
               temp = temp + in.readLine();
               System.out.println(" line : " + count + " of 98441!");
               //textArea.append(in.readLine());
          textArea.append(temp);
     } catch (Exception e) {
          e.printStackTrace(System.err);
thanks for any help

Thanks for the tip... performance wise its great.. but it still hangs/stops after 23189 lines.. i can only assume theres a limit to how much String and StringBuffer can hold, so StringBuffer isnt good enough to store my 5 megfile to display in a textArea.
any advice.

I have Lightroom 1.4.1 and I just started shooting the Nikon D700. I cannot get Lightroom to read my new raw files, help...

I have Lightroom 1.4.1 and I just started shooting the Nikon D700. I cannot get Lightroom to read my new raw files, help... Is there a plug in or update I can get? I can't afford new software after new camera and new lense!

Lightroom 1.4.1 does not support native (NEF) files from the D700 because the camera didn't even exist when it was released. To get support you have two options: upgrade to Lr 2.x (paid for upgrade) or convert your NEF files to DNG.
DNG converter 5.4 can be downloaded from http://www.adobe.com/downloads/ (see right hand side of page)

Problem reading DVC PRO native files

Hello
I cannot read DVC PRO native file using either my Quick Time Pro 7 or my final cut Pro 5. I only get the sound track with no image. I downloaded the DVCPRO component and installed it. Still no success. Can someone help ?
Thanks

Are you referring to DVCProHD files from a Panasonic HVX or HPX?
You aren't clear.
If you are, the mxf files have to be transcoded to DCProHD using import p2 command in FCP.

Remote app problem - read everything and still no help

Hi
Similar to many people, I'm having a remote problem as well. Actually, the app worked just fine for a week, then all of a sudden stopped working. I guess it could have been some kind of a windows update issue maybe because I haven't changed anything. The thing is now that it's trying to connect to my library but fails. I've turned my firewalls completely off, re-installed the app many times on my iPhone 3G, re-added the library many times (then it connects so I can insert the 4-digit code), tried the "forget all remotes", the sharing is enabled in iTunes, I'm connected to the same WiFi network, it's not hooked with a cable to sync when I've tried it but still, all it says is "could not connect to library". I have been working with this issue for 2 days by now and read hundreds of posts but still no help. Could please anyone help me with this issue, please please!
Thanx

Try this
In Windows go to Start - Run - type services.msc then press ok
Look for Bonjour Service - is it started? if not right click on it and start it
If it is started right click and restart the service. Now try remote app

Problems reading from / writing to files in C on XCode 3

Hi all,
I'm a newcomer to C, having been learning for about a week and a half. All going well so far.
I'm working through Dave Mark's 'Learn C on the Macintosh' e-book, and am up to Chapter 10, 'Working with Files.' Herein lies the problem.
I can't get any of the file-related commands to work. The most basic, it seems, is 'fopen()'. There's a very simple demo program which is supposed to open an accompanying file ("My Data File.txt") which is in there with main.c and so on. Nothing happens, though. I've tried it with a 'w' mode parameter which should create the file if it doesn't already exist, but Spotlight can't find it if it is indeed being made.
I'm using a fairly vanilla install of XCode 3, so I shouldn't have messed up the settings anywhere along the way. I've tried all of the different path types in the 'Get Info' dialogs, but still nothing.
I guess that it's something very basic that I've missed or not understood. If any of you could take the time to help me out, it'd be much appreciated.
If there's any further information you need, please just let me know.
Many thanks,
Pete.

Ok I'm new to c programming and xcode and I have this same problem but the suggestions have not remedied my problem. I get this warning:
"warning: no rule to process file '$(PROJECT_DIR)/operations.txt' of type text for architecture i386"
This is my code
#include <stdio.h>
#include <math.h>
int main()
char filename[128],fvalue1[128];
int x=0;
FILE *input;
printf("Enter name of file: ");
fgets(filename,128,stdin);
if((input = fopen(filename,"r"))==NULL)
printf("Failed to open file.\n");
x=1;
if(x!=1)
fgets(fvalue1,128,input);
fclose(input);
fflush(stdin);
printf("\n\nPress enter to continue...");
getchar();
return(0);
I think its a setting but I dont know what else to try.
Any further input on this would be greatly appreciated. thanx

Problem reading ebook on ereader, file nog available with adobe ID

I have installed Adobe Digital Editions 4.0, made an account and downloaded some books.
Then i've linked my e-reader to the same account and transfered the books to the e-reader.
I see the icons of the books in the library of my e-reader, but i can't open them, it says: "This file cannot be opened. This document is protected by Adobe Digital Rights Management (DRM) and is not available with your Adobe ID. Log in with the authorised Adobe ID and try again."
I am able to read the books on my computer, but not on my ereader, while I use the same account.
Can you help me?

Thanks for the response, but I'm acessing DVD content - not any website online.
It's the DVD's flashplayer (ver. 10.00xxxx) that freezes the DVD and makes the audio data inaccessible.
The short fix is to play the audio files separately from another program, but I'd prefer to have just the DVD on its own.
Just to clarify, I've sent an email to the technical support of the DVD producer, we'll see if they can resolve it.
Thanks Again.

Well, you are probably passing in a line that is tokinized into less than 14 tokens.
Add some debug output that prints the line that you are tokenizing.
Use hasMoreTokens and countTokens to determine if it is ok to call nextToken or if you are already out of tokens.
E.g. you could do something along these lines:
fixed token count formatprivate void tokenize(final String line)
final StringTokenizer st = new StringTokenizer( line, "|" );
if ( st.countTokens() != 14 )
     throw new RuntimeException("Invalid token count: " + st.countTokens());
FName = st.nextToken();
}variable token count formatprivate void tokenize(final String line)
final StringTokenizer st = new StringTokenizer( line, "|" );
if (st.hasMoreTokens())
    FName = st.nextToken();
if (st.hasMoreTokens())
    MName = st.nextToken();
}

Problem with permissions on old files help?!

So recently my mac pro hard drive failed and I had to get a new one..fortunately they were able to manually migrate all my data..All my music and production files..vsts and various sound packs..The thing is my last hard drive had a password so now I can see my data from my old hard drive but I do not have permission to open the folders up let alone use them...How do I give my new hard drive the permissions to access/open/use my old data??? I am relatively ok when it comes to computers but not for something like this..I know it has something to do with running the terminal but once I get into that, its basically all charlie brown..Is there anyone out there willing to help a dummy out My files are extremely important and I've invested 1000's of dollars on them..Yes, yes I know now I should have had them on an external but I never thought my macbook hard drive would fail a year after buying it..Please I would really appreciate some help..thanks!!

I received this warning:warning: SUID file "System/library/coreS...as been modified and will not be repaired.
It's not really a warning but messages re SUID which according to Apple can be ignored > Mac OS X: Disk Utility's Repair Disk Permissions messages that you can safely ignore
The SUID mesages in no way are related to the Silverlight plugin issue.
As for Silverlight go to /Library/Internet Plug-Ins. Make sure you see the Silverlight plugin in the Internet Plug-Ins folder.

Corsair is a good brand, but those DDR2 modules are already overclocked.

How to read back a xml file

hi all
I have a problem reading back an xml file.
What I want to do is to store sensors and some vi parmaters.
To do it, I put the parmaters in a cluster, flaten it to xml and then write the xml file.
till here, no problem.
When I want to read back the xml file, it doesn't work with the way I do (I use unflaten and read xml file)
The datas i read back are not those I want to take back from my xml file.
Can somebody help me with this point?
The 7 datas filed are :
string
string

Hi,
there are two examples in Help >> Example Finder >> Fundamentals >> File Input and Output. One is Write Data to XML File and the other is Red Data from XML File. The first will write it and the second will read it back.
I expanded th example with the String data and the value provided in your post and it work even with the '/' in the data.Message Edited by waldemar.hersacher on 04-06-2005 11:23 PM
