Multi file reads opinion

What do you think is the best way to read and compare multiple files? At the moment I am in the process of creating a class that does this, and I am reading all the lines of the files into individual collections for each file and then comparing the lines of the collections. Is this a good or bad technique. What would you suggest?

I've been handed this printout of VB code and told to convert it (without even a clue what it does). All I was told is that I need to make this so it can be used by many programs, it'll have to be able to read in any number of files, and files are variable in size (could be a couple hundred lines to a couple million lines). From what I can make out from the code is :
It's taking a substring from each line of one file then searches the other files for that same substring.
I was just wondering if there was a better way of doing this. Because this has got to be very slow for the larger files.

Multi files reading and plotting

i got three text files to be read and i wana plot them on a single chart ,how can i do that ?? bundling them??
And is there any way to write three different values on a single file in three columns ??? i m doing it with matlab ? is there any direct way??

Hello,
See if the attached file it's enought.
For writting the 3 different values in 3 columns, use the "write to spreadsheet file.vi"

How to read multi files?

Hi !! Can anyone tell me the syntax of reading mulit txt files? Thanks. I only know how to read single file.
try
//Search file
System.out.println(" ");
System.out.println("Search file :");
File file = null;
String fileloc = "c:\\j2sdk1.4.1_06\\bin\\PAYMENT.TXT";
file = new File(fileloc);
//If Payment interface file exists
if (file.exists()) {
System.out.println("File exists !");
System.out.println("");
}

Hi!! How to read multi files (For example: dbExport1.txt , dbExport2.txt , dbExport3.txt ...... => dbExport*.txt) ?
I only know how to read a single file.
try
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
     conn = DriverManager.getConnection(url, userid, password);
stmt = conn.createStatement();
     if (conn != null)
     System.out.println("Connection to Database OK!");
// read it
BufferedReader br = new BufferedReader(new FileReader("c:\\document\\dbExport.txt"));
DataInputStream in = new DataInputStream(new FileInputStream("c:\\document\\dbExport.txt"));
String input;
String firstinput;
String secondinput;
int count=130;
int year=1955;
while ((input = br.readLine()) != null) {
firstinput = input.substring(0, 10);
secondinput = input.substring(10);
count = count + 1;
System.out.println(firstinput);
System.out.println(secondinput);
String insertStore1 = ("INSERT INTO AUTHORS " +
"VALUES ('" + count + "', '" + firstinput + "', '" + secondinput + "', 1955)");
     System.out.println(insertStore1);
boolean result;
if (stmt.executeUpdate(insertStore1) == 1){
System.out.println("Insertion successful");
else{
System.out.println("Insertion failed");
br.close();
     stmt.close();
     conn.close();

Multi-thread file reading

Hi,
I've got a tricky question: I have to read large files (over 150 MB) - I found here several topics about reading such a large files, but all examples were about single-threaded reading from file... Do you think, multi-threaded reading would be faster? I am in quite a dilemma: multiple threads in general means faster processing, but in this case, all threads are reading from the same source/file
(I use javax.mail.util.SharedFileInputStream for multi-threaded file reading - each stream in separated thread)
so what do you think, which is faster: single-thread or multiple-thread? and if so, how many threads would be fine - 2, 3 or 4?
thanks a lot

so it seems to be just like I wrote some posts before: while one thread is reading data from file, another could process already read data - I am just considering malcolmmc's idea of blocking queue - one thread to perform I/O operations and one thread to process data - these threads would be connected through blocking queue....hmm that sounds good to me.. thanks malcolmmc
thank you guys for your help & suggestions and if you still have something to advise me, I will be thankfulSeparation of concerns, dude. Read the raw data in, in one thread, and split out the processing to multiple threads. I really advise you take the time to actually measure the performance of the multi-threaded processing vs the single-threaded one though. I mean, really do actually do that. Don't just assume - as so many people do - that throwing more threads at every problem will always speed it up, because it's so often not the case.

T510 Windows XP 64bit - Multi Card reader no longer working

Just installed XP 64 bit from XP 32 because i finally got tired of windows only recognizing 2GB of RAM.
I have just discovered the multi card reader no longer works (it worked just a few days ago with the 32 bit xp).
i have tried uninstalling and reinstalling the driver (6hss03ww.exe - Ricoh Multi Card Reader Driver) several times, with no luck.
i do not have any uninstalled drivers, or highlighted items in the device manager.
Has anyone else ever has this issue, or can offer some advice? i am a bit at a loss... and ready to dump this thing out the window and buy a mac...

Hello mate,
Lenovo doesn't support windows xp 64-bit. If you have a look in the readme file it says
Added support for Microsoft Windows XP Professional x64 Edition (on ThinkPad
W510 only).
Install windows vista or 7 if you want a 64-bit OS.

Just 2 things in my test:

Restricting the type to application/octet-stream may generate errors. Also, it is unnecessary, because we perform a type check anyway.

Memory Card "Stuck" in A720 multi-card reader

This is an embarrassing situation. Really appreciate if someone can give me some idea.
I just got the A720 for a few days. I used SD cards fine with A720's multi-card reader, but last night when I (gently as with the SD cards) slotted in a regular Sony memory stick in it (6-in-1, accepting MS/ MS Pro), the whole stick moved beyond the opening and well into the slot. The A720 could detect the card and I immediately copied all the file into the HD and ejected it on Windows.
Now the memory stick remains in(side) the card reader slot, and I dare not touch it further lest it goes further inside. Is this a design flaw? I was appalled and am frustrated by how this could have happened -- I actually used my little finger to slot the card in!. I bought the A720 mainly for photo post-processing.
Any idea I can get the stick out (and even better slot it in without the same happening again)? Thank you.

Hi
Welcome To Lenovo Community
There are various reason for a memory card to get stuck inside the card reader
Most common is the direction in which the card is inserted, size of the card also matters or any obstacle which is their inside the card reader.
Push a little harder on the card and it might pop out. The spring mechanism on the inside is designed to release once it is pushed past a certain point.
If this doesn't work, you need to force it out using a flat tool. To do so Turn off your system , Press the Power Button for 15 seconds to drain out the remaining charge
Now use a needle nose pliers, areal long thin one. And gently pull the memory card out.
You can also try using a paper clip apply glue on the edge. Very tiny amount that won't drip push clip in and touch the back of the card. Wait until it is hard in about 15 secs and pull the card out.
if this does not work contact Local Lenovo service center , we need to open the card reader to remove the memory card
Hope This Helps
Cheers!!!

Automating multi-file Flash using XML file "run list"

I've created a multi-file interactive Flash "demo" for a client. It's very much like a website (though he's not using it as a website) in the way that it is laid out in that there is a main index page which can then direct you to different product categories, which you can click on to see. Each "page" contains product (or product category) information, photos, block diagrams, etc. There is nothing animated in the Flash.
My client also wants to be able to set it up so that the demo runs automatically from a configurable XML file. My ActionScript skills are pretty limited, but I've been able to using ActionScript 3 to load and read the XML file. Using a 'for' loop, I am able to read the XML file and return the path of each Flash file and the duration that each file should be displayed (my client requested that he be able to configure the duration of each page as well).
I've set up a loader for each movie clip and a timer for the display duration. Unfortunately, the thing that is throwing me off is that when I attempt to load the movie clip (as the last item in the for loop), it reads the entire XML file, returns all of the clips and durations (I'm using trace to see this) before it loads the movie clip. As a result, the only movie clip that is loaded is the last one read from the XML file.
As I said, I'm not very good at ActionScript, so everything that I've managed to cobble together has been from internet tutorials.
This is my code:
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
var mcLoader:Loader = new Loader();
mcLoader.contentLoaderInfo.addEventListener(Event.INIT, playClip);
var mcCurrent:MovieClip = new MovieClip();
stage.addChild(mcCurrent);
var xml:XML;
function playClip(e:Event):void
    trace("Function:playClip");
    stage.removeChild(mcCurrent);
    mcCurrent = MovieClip(mcLoader.content);
    mcLoader.unload();
    stage.addChild(mcCurrent);
function xmlLoaded(e:Event):void
    trace("Function: xmlLoaded");
    xml = new XML(e.target.data);
    var cl:XMLList = xml.clip;
    for(var i:uint=0; i<cl.length(); i++)
        trace("Begin 'for' loop");
        trace("variable 'i' is" + i);
        var clipPath = cl[i].@path;
        var delay = cl[i].@duration;
        trace("Clip path is " + clipPath);
        trace("Display for " + delay);
        mcLoader.load(new URLRequest(clipPath));
xmlLoader.load(new URLRequest("filerunlist.xml"));
I removed the timer event because it, like everything else was getting repeated before anything got loaded, so I wanted to figure out out to get the clip loader (mcLoader) to load the movie clip for each file before I figured out where to put the time to ensure that each clip is displayed for the appropriate duration. I suspect that the timer event needs to occur in the 'playClip' function, but would take advice on that as well.
Thanks to anyone that can help me figure this out.

What you need to do in the xml parsing function is to simply store all of the data into an array. You will then use that array one element after another via whatever timer control you set up, accessing each file in the order they are stored in the array. You will not do any loading in that function, just data storage, and when you are done, the last line in that function, outside of the loop, will trigger whatever function you have that will start processing the first item in the array.
Example, storing data objects in the array...
var clipData:Array = new Array();   // store your xml data here
var clipToShow:uint = 0;                   // use this later in the showClip function
function xmlLoaded(e:Event):void
    trace("Function: xmlLoaded");
    xml = new XML(e.target.data);
    var cl:XMLList = xml.clip;
    for(var i:uint=0; i<cl.length(); i++)
        clipArray.push( { clipPath: cl[i].@path, delay: cl[i].@duration } );
    showClip();
function showClip(){
     // do whatever to process loading clipArray[clipToShow].clipPath
     // and using clipArray[clipToShow].delay for starting whatever timer is involved
     // the timer event handler function will call this function when it is executed
     clipToShow += 1;   // increment the counter for the next clip in line
If you are not comfortable/familiar with the object approach, then you could also store the clip and delay data in two separate arrays.

RFC to multi file scenario

Hi,
I have to carry out a RFC to multi-file scenario. The requirement is that Error generating on whatever part XI will handle have to be reported. Is this possible in this scenario? What can be the mechanism?
I want to report these errors via a mail to an e-mail id.
Since i haven't done this scenario, i would appreciate if some link for carrying this out step-by-step is given.Also tell me what configuration for receiving RFC has to be done on XI and R/3.

For some reason FCP is now making multi files when I capture called -av

For some reason FCP is now making multi files when I capture called -av
I capture one clip but I get 7 files.
sineparade live-1-av 1.91 GB
sineparade live-2-av 1.91 GB
sineparade live-3-av 1.91 GB
sineparade live-4-av 1.91 GB
sineparade live-5-av 1.91 GB
sineparade live-6-av 334.1 MB
sineparade live-av 1.91 GB
I don't know why this started in recent captures but it is eating up disk space as it is 7 times larger than it needs to be and only the last one works.

Is there a way to get these files to be joined together into one file easily. I capture on a FAT32 hard drive but then transfer the files onto my edit machine and would prefer to keep everything archived there as a single file.
Any programs or scripts that I can use. I have figured out that you can open each file in Quicktime and then save as a self contained file, but I was wondering if there is a better way.

Multi File Find and Replace FAR missing from tools

I have RoboHelp x5.0.2 and I have always used Find and
Replace at my previous employer. I have started with a new company
and the RoboHelp FAR is missing from Tools. I know you can Add a
tool if you know the path, but I have no idea where to look.
Some background:
We use Source Safe (VSS) to check our files in and out.
I have verified that all of the files are NOT read-only.
HELP!!!!

Maybe you are mixing up something. RoboHelp includes a tool
named Multi-File Find and Replace. This should indeed be situated
on the Tools pane.
There exists a tool called FAR, which, among other things,
offers a similar functionality. FAR is shareware and
not included in RoboHelp.

Multi File upload

I want to develop a functionallity for MultiFile Upload, is it directly supported in JSF 2.2 or i have to use some other implementation of JSF such as RichFaces or ICEFaces.

Hello,
Why don't you just make a portal form for them ?
Making a portal form based on the table (the one holding the BLOBs)
will generate multi files upload automatically
Is this what u need ?

Attaching multi files to javamail?

Am trying attach multi files to a javamail, but when I do javamail sends the last file multi times? Somehow it copies the last file to the other files and sends it multi times. This how I do:
MimeBodyPart textPart = new MimeBodyPart();
textPart.setContent(body,"text/plain");
Multipart mp = new MimeMultipart();
MimeBodyPart attachFilePart = new MimeBodyPart();
for(int i=0;i<filListe.size();i++)
File vedhaeftetFil = (File)filListe.get(i);
FileDataSource fds = new FileDataSource(vedhaeftetFil);
attachFilePart.setDataHandler(new DataHandler(fds));
attachFilePart.setFileName(fds.getName());
mp.addBodyPart(attachFilePart);
System.out.println(fds.getName());
mp.addBodyPart(textPart);
msg.setContent(mp);
Transport.send(msg);
Can someone tell me how I can solve this?

lol....
MimeBodyPart textPart = new MimeBodyPart();
textPart.setContent(body,"text/plain");
Multipart mp = new MimeMultipart();
MimeBodyPart attachFilePart;
