How do I check/limit the size of a file

I am logging data to a file periodically. Since the PC is at a remote site, and I download the data file via modem, I want to limit the size of the file by automatically starting a new file once the current file reaches a certain size (in kB) limit. This way I minimize download time as well as avoid downloading the same data over and over again if I keep the same filename.
How can I do this? Thanks.

There is a function on the File I/O>Advanced File Functions called File/Directory Info. The functions returns the file size in bytes.

Using log4j.xml to limit the size of a file

Hello,
I'm using JBoss. On startup it writes to boot.log and server.log. I'd like to limit the size that server.log can reach. At the minute I'm using the following code:

   <appender name="FILE" class="org.jboss.logging.appender.RollingFileAppender">
     <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
     <param name="File" value="${jboss.server.home.dir}/log/server.log"/>
     <param name="Append" value="false"/>
     <param name="MaxFileSize" value="3KB"/>
     <param name="MaxBackupIndex" value="1"/>
     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
     </layout>
   </appender>However this causes far more information to be written to boot.log than usual and nothing to server.log.
Can anyone help me in where I'm going wrong?
Thanks very much,
Ger

Solved.

How can I limit the size of a file upload?

I am uploading a file using a file reference using the code below. I want to limit the file size (bytes) of the uploaded file to 100k, so that a huge file won't crash the browser or my SWF.
What's the best place in the following process to test this, and actually prevent the large file from being loaded? Is that even possible?
private function uploadImageBtn_clickHandler() : void {
     var arr:Array = [];
     arr.push(new FileFilter("Images", "*.gif;*.jpeg;*.jpg;*.png"));
     fileRef.browse(arr);
private function fileReference_select(evt:Event):void {
     fileRef.load();
private function fileReference_complete(event:Event):void {
     var loader:Loader = new Loader();
     loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loader_complete);
     loader.loadBytes(fileRef.data);
public function loader_complete (event:Event) : void {
     trace("Loader info = "+event.currentTarget.bytesLoaded); // file size in bytes
     var sourceBMP:Bitmap = event.currentTarget.loader.content as Bitmap;
     bgImage.source = sourceBMP;

Thank you. I just needed to be pointed in the right direction. After looking over this stuff, including FilePermission, I think this may give me what I was looking for. It will be a while before I get to implementing it or testing something like this, I'm just trying to get a grasp on all of the things I need to do and how to approach it.
By doing this I can control how much filespace it can use.
I can control CPU usage by monitoring for extra threads that don't belong and killing or settings the priority on it.
Now I just need to think of something to monitor how much memory the plugin uses. I suppose I could gc, then store the current memory usage, then execute the plugin, gc again, and measure the size again. Does that sound like a reasonable way to estimate it's memory usage? I'm not looking for tiny changes, I just want to see large, substantial increases.

How can I limit the size of a file generated by 3rd party code?

I have a program that loads plugins from a directory and executes code in those plugins. These plugins are classes that implement a standard interface within my API. I want to be able to monitor for files generated by these plugins. Usually there are no more than 2 plugins running at once, so I could end up with 2 plugins writing files. An example would be a plugin creating an SQLite database on the filesystem.
I could monitor the current directory and guess who's file it is, but what if the files get written elsewhere? Can I do something in Java that limits what directories the Java process can write to?
I wouldn't mind being able to track their memory and CPU usage, but I don't think I can do much about that.

How do I find out the size of a file, trying to make a DVD and told the fil

Made a slide show project with music and trying to write to dvd. Computer tells me the file is to large and to use a dual sided disk. I cut may slides out but no luck. How do you find out the file size?

Hi
And SlideShows has a limit of 99 slides per show.
I rather assemble mine in iMovie HD 6 where as QuickTimeKirk states
it only has Time as a limit dep. on encoding method selected and if Single or Double layer DVDs
Single Layer (for DL double time) - TIME includes menu - keeping it simple gives more to movie.
(I prefere "Brushed Metal" no audio, no animation.)
• Professional Quality (movies up to 120 min.) - BEST
• Best Performances (movies less than 60 min.) - High quality on final DVD
• High Quality (in iDVD08) / Best Quality (in iDVD6) (movies up to 120 min.) - slightly lower quality than above

Is it possible to make a constraint such that this file size mustn't exceed certain size
let say 5 MB for instance :)

How to limit the size of a log file.

Hi,
I am developing an application that creates a log file with all actions that take place. My problem is that this log file grows a lot because the application acts as a server that is up 24 hours a day. For that reason, I wanted to limit the size of the log file by deleting de older lines, how can implement is?
Thanks.

One way is to periodically (say every week) create a new file to store the actions and then, when the space taken up by all the files is too large, delete the oldest one.
You can also have your application periodically (say the first time you write to the file on any calendar day) check the size of the file and, when it gets too big, copy all of the actions in the file after a given time (presumably there is an associated timestamp with each action) to a new file. Then delete the old file.

How to check/find the size of current ROLLBACK segment in oracle 10g

How to check/find the size of current ROLLBACK segment in oracle 10g ? Kindly help

A rollback segment name like "_SYSSMU231$" is used when you have Automatic Undo Management enabled.
The only relevant parameters are :
1. UNDO_MANAGEMENT=AUTO
2. UNDO_RETENTION=n minutes ==> this is what everyone should be interested in
3. The sizes of the Undo Tablespace datafiles and whether AUTOEXTEND is ON or OFF
No one should be interested in the size of a single undo segment when Automatic Undo Management is enabled.
Possible causes of ORA-01555 errors in Automatic Undo Management
a. UNDO_RETENTION is too low
b. Undo tablespace is too small

How to limit the size of bounced messages

Hi,
how can i limit the size of bounced messages?
In most cases, we have users which accounts are over quota, the mail bounces and is returned.
How can i limit the size of the returned message to a maximum size of 1MB?
We're using
iPlanet Messaging Server 5.2 HotFix 2.02 (built Oct 21 2004)

thx,

Ah. found it. It is indeed in 5.2
http://docs.sun.com/source/816-6009-10/mta.htm#24585
look down the page, and find:
CONTENT_RETURN_BLOCK_LIMIT
this when put in the option.dat file will limit your response to the
CONTENT_RETURN_BLOCK_LIMIT=
number of 1k blocks.

How to limit the size of the connection method parameter

I connected an FMS server like var nc = new NetConnection ();
nc.connect ("rtmfp :/ / localhost: 61018/zy/1", a);
But how to restrict the size of the parameter a, assuming that this a set to a 10GB object, or a very large byte, I found that the server received. This allows the hacker attacks, Is there any way to limit the size of this a, I hope that does not exceed 100KB.

RTMFP encodes low-level messages in a manner compatible with RTMP messages. RTMP messages are length-field limited to 16MB (24 bits), and there is an artificial software limit somewhat less than that (approximately 10MB if i recall correctly).
it should not be possible to send a connect message to an RTMFP or RTMP server exceeding about 10MB.
ByteArray is limited to 4GB, and can't be serialized to AMF beyond 512MB (29 bits).
also keep in mind that for an RTMFP or RTMP server to receive such a large message, that many bytes must be sent to it from somewhere (you).

How do I change the color of font in a fillable form in Adobe Reader? How can I check if the writer of the document has given permission to edit color and not just add text?

How do I change the color of font in a fillable form in Adobe Reader? How can I check if the writer of the document has given permission to edit color and not just add text? Please help! I'm technologically challenged.

Most forms (99% or more) are created for simple text input, where you cannot change anything.
The creator of the form could allow Rich Text input (which allows you to change font, text size, color, etc.), but frankly I have never seen such a form, and I wouldn't know how they look. But I'm sure they would show some kind of controls to alter the text appearance.

How can i change the size of PDF files ?

how can i change the size of PDF files? when i convert documents in the acrobat browser it seems the files become larger then normal pdf files, this is, i compare with other files that people send to me and i realise that they are smaller than my converted files, even if they have more pages.

A lot depends on the form of the PDF. Is it graphics, a scan of a text file, pure text, or other? What version of Acrobat are you working with.
You can do a save as to get a WORD file, but do not expect great results. The ability to get a decent WORD file depends on what the form of PDF you are working from. If it was created from WORD with tags and all, you might get good results. If not, you might get a lot of messed up results.
Explain what you are starting with and your ultimate goal. Also check the audit of the file (should be under PDF Optimize) to see where the file information is concentrated (text, fonts, graphics, other).
