URLConnection getContentLength() DOES return the size of the file ?!
Hi,
Just writing a method that will retrieve a few files from an FTP server, and noticed something that I thought was weird (but that may be because I am not too well-versed in matters computing).
The getContentLength() method in URLConnection does appear to return the correct filesize for the remote file.
This is (an abstract of the code I use)
try
URL url = new URL("ftp", host, -1, pathToFile);
URLConnection uc = url.openConnection();
uc.connect();
long filesize = (long) uc.getContentLength();
System.out.println("filesize = " + filesize);
....For one reason or another, and despite all the articles on the forums here that appear to say it won't, this retrieves the correct filesize for the file I have yet to download.
Strange thing is, as getContentLength() returns an int, I wouldn't have thought that simply casting it to long would get the right number.
Can anybody with computing knowledge explain why this works?
Thanks in advance
Jaap
never mind... I found the answer. I think.

Does anyone have a simple program that will return the size of a file
Does anyone have a simple program that will return the size of a file?
I quite hate it when I receive the incorrect amount of yoctocandela per metre squared. Swarthy people
can't properly convert poundal feet to barleycorn; throws off the whole conversion! Aaah, you get what
you paid for.I recognize those figures; you've got your outsourced file sizes from Zanzibar; admit it! I always apply
the scientific approach when I've got file sizes back from Zanzibar: I simply divide those numbers by
pi (very scientific) and drop the eleven (ueber scientific, because 11 is prime even when looked upon
as a binary number) least significant bits. And remember: never compare two floating point numbers
for equality. (<--- that's a free tip)

When does a JTabbedPane set the size of the component inside a tab?
I would like to know how big a component inside a tab is directly after I've added it to a tab in a JTabbedPane.
I thought once I've "added" a component via the JTabbedPane.add(String, Component) method, the Component would be realized with correct sizes.
Where or when should I request the information about how big a component has become inside a tab??
Example:
1. "Add" a tab via the menu.
2. Notice that the size of the panel has not changed even though we see it on the screen.

Trying to return the size of the bag's range
can some one help me with these... im not sure if i just need to do a return statement. if someone can give some advice that would be great.. thanks
public interface BagOverIntRange {
* Returns the size of the bag's range (high - low + 1).
// do i need to scan this ? or is this more simple?
public int rangeSize();
* Returns the lower bound of the bag's range.
public int rangeLow();
* Returns the upper bound of the bag's range.
public int rangeHigh();What are you talking about. You posted an interface definition, and the method definitions in it look ok. I don't understand the question in the comment of the rangeSize method definition. It's just a definition in the interface, not an implementation.

What does not affect the size of the classfile
Hi
does inclusion of extra whitespaces affect the size of the classfile (that gets created after compiling).
does inclusion of java comments increases the size of the classfile.
are there any other things that when included, does not affect the size of the classfile.

Madhu_1980Shouldn't you be worried about getting your program working by using the right constructs rather than constructs which result in a smaller .class file?
Are you restricted on the sizes of your .class files? -
Hello,
I am at my wits end into this. Either I am doing it the wrong way or it is not possible.
Let me explain. I need a vb script for the following scenario:
1. The script is to run on multiple Windows 7 machines (32-Bit & 64-Bit alike).
2. These are shared workstation i.e. different users login to these machines from time to time.
3. The objective of this script is to traverse through each User Profile folder and get the size of the 'My Documents' folder within each User Profile folder. This information is to be written to a
.CSV file located at C:\Temp directory on the machine.
4. This script would be pushed to all workstations from SCCM. It would be configured to execute with
System Rights
I tried the script detailed at:
http://blogs.technet.com/b/heyscriptingguy/archive/2005/03/31/how-can-i-determine-the-size-of-the-my-documents-folder.aspx
Const MY_DOCUMENTS = &H5&
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace(MY_DOCUMENTS)
Set objFolderItem = objFolder.Self
strPath = objFolderItem.Path
Set objFolder = objFSO.GetFolder(strPath)
Wscript.Echo objFolder.Size
The Wscript.Echo objFolder.Size command in the script at the above mentioned link returned the value as
'0' (zero) for the current logged on user. Although the actual size was like 30 MB or so.
I then tried the script at:
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/VB_Script/Q_27869829.html
This script returns the correct value but only for the current logged-on user.
Const blnShowErrors = False
' Set up filesystem object for usage
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
' Display desired folder sizes
Wscript.Echo "MyDocuments : " & FormatSize(FindFiles(objFSO.GetFolder(objShell.SpecialFolders("MyDocuments"))))
' Recursively tally the size of all files under a folder
' Protect against folders or files that are not accessible
Function FindFiles(objFolder)
On Error Resume Next
' List files
For Each objFile In objFolder.Files
On Error Resume Next
If Err.Number <> 0 Then ShowError "FindFiles:01", objFolder.Path
On Error Resume Next
FindFiles = FindFiles + objFile.Size

Next
If Err.Number = 0 Then

If Err.Number <> 0 Then ShowError "FindFiles:04", objFolder.Path
FindFiles = FindFiles + FindFiles(objSubFolder)
If Err.Number <> 0 Then ShowError "FindFiles:05", objSubFolder.Path
Next
Else
ShowError "FindFiles:03", objFolder.Path
End If
End Function
' Function to format a number into typical size scales
Function FormatSize(iSize)
aLabel = Array("bytes", "KB", "MB", "GB", "TB")
For i = 0 to 4
If iSize > 1024 Then iSize = iSize / 1024 Else Exit For End If
Next
FormatSize = Round(iSize, 2) & " " & aLabel(i)
End Function
Sub ShowError(strLocation, strMessage)
If blnShowErrors Then
WScript.StdErr.WriteLine "==> ERROR at [" & strLocation & "]"
WScript.StdErr.WriteLine " Number:[" & Err.Number & "], Source:[" & Err.Source & "], Desc:[" & Err.Description & "]"
WScript.StdErr.WriteLine " " & strMessage
Err.Clear
End If
End Sub
The only part pending, is to achieve this for the 'My Documents' folder within each User Profile folder.
Is this possible?
Please help.Here are a bunch of scripts to get folder size under all circumstances. Take your pick.

How to change the size of the caret in a JTextPane
I have text of different font sizes and the default caret height is the height of the text with the maximum font size. How do I change the caret height so that it matches the height of the text with the specified font size ?
This has been a real pain in the butt to figure out, but I think I finally got it. If you create your own caret (subclass of DefaultCaret) then you override its paint() and damage() methods. I was having all kinds of problems with this though. I was getting pieces of carets left behind when I moved with the arrow keys, etc... from the helps I found. The arrow keys were my big problem.
I think I finally figured out that the damage() simply does need to specify an area a little bigger than the old caret so it can blank it out. Then I think others had a logic problem, and Sun does not make this problem clear. What happens it that I think repaint() calls paint() who then uses the bigger x, y, height and width parameters that got set in damage(), which was causing my problems because the damage size was bigger than the size I wanted to create my caret with. What I do is figure out my area from the font I am using (another trick) and make them (the charWd and charHt) variables class variables. I calculate them in damage, use a bigger area to blank out my old caret in damage, and then used the correct caret size I calculated in damage() in paint(), instead of the rectangle values that seem to get passed from damage() to paint(). That was the problem in other examples.
Here is my code:

Getting the size of a file on the application server ?
hi,
hi everyone !
i' m trying to transfer a file with the function module FTP_R3_TO_SERVER...
But for this, i need to know the size of the file i wish to transfer...
I found out nothing about this, but if anyone have any idea, it would be really helpful...
thnks.HI,
Why don't you use a ShellScript for FTPing your file.
You can execute it via ABAP and it will probably does the same
but you don't have to know how big the file is.
can think of a few:
1) Check the F1 help on READ DATASET. It has the addition LENGTH which you should be able to use for this purpose.
2) Call function SXPG_COMMAND_EXECUTE for command LIST_DB2DUMP. Parse the returned table. You may need to explicitly pass 'UNIX' or 'Windows NT' to the OPERATINGSYSTEM parameter.
3) CALL 'SYSTEM' ID 'COMMAND' FIELD 'ls -l' ID 'TAB' FIELD result-sys.
4) Disect AL11 and make use of the same C-calls
There's probably more...
if u r sending the data form presentation server (SAPFTP)
use
describe table itab line lin .
size = lin * width of internal row
If u r sending the data form application server
read the data in applicaion server file in ur prg internal table and calculate as above and size of file in ftp_r3_to_server fun module

How to get the size of the webpage?
I am designing a program to
analyse the webpage content.
wondering how to get the size of
the webpage including its image's
size and etc. Thanks in advance.As i know , the getContentLength just return
then number of characters of its HTML code.
By knowing the length of the HTML code, is
not possible for me to calculate its download

BI Publisher 10g - Limit to the size of the data model?
Hello,
We are using OBIEE 10g 10.1.3.4.1 in our organization and have a problem when working on a large report in BI Publisher. It seems that once our data model gets large enough, we are no longer able to edit the report. When we click on the Edit link to load the report editor, the side menu that lists the data model, parameters, bursting, etc does not load, preventing us from making any changes to the report.
At first we thought it was a timeout issue and changed the following:
$J2EE_HOME/applications/xmlpserver/xmlpserver/js/XDOReportModel.js
Property name : XDOReportModel.TIMEOUTMSEC
set value in Milli seconds as " XDOReportModel.TIMEOUTMSEC = 15000
After making the change and restarting the services, it did not help. Is there a different place for the timeout of loading the report editor? What about some kind of cap to the size of the data model? We have one large data template that is used to generate a report. I tried breaking the large data set into multiple, smaller data sets (still using data tempalte) and that didn't seem to help any. Is there a limit the size of the data model BI Publisher can return?
Any help would be greatly appreciated! Thanks!Hello,
I think you should create a recordStore with RMS and use it like a string array. You can store huge amount of data and the time access when request data from recordStore is very similar as if it is store on the RAM memory with recent devices.
And if it is not persistent data you can delete the recordStore when closing the midlet. -
# of objects, not the size of the objects, determine size of a Collection
There are objects, and references to objects.
Do, List / Set / Map , etc. just maintain a list of 32-bit addresses for their contained objects? What more does a Collection need, memory-wise, to add an element? The size of the objects in a Collection should not matter?
listA.add(new Integer(2)); // listA size grows by 32-bits
listB.add(new GiantSizedClass()); // listB size grows by 32-bitsI started thinking about Collections being able to dynamically grow in runtime. I heard this is complex, but it "looks" like all you do is append a memory address and incriment a counter? This sounds quick, easy, and incorrect. I don't understand. Thanks.jverd, ejp: you have always been there with quick responses to help me. ejp, i purchased your book "Fundamental Networking in Java". When I start programming again, your book about RMI is on my list. that said.
with all sincerity. i belived that serliazing objects in byte[] allows for storing objects in objects, not object references in objects. here is my test code (just cut/paste):
My idea seems similars to me as cryogenics and so that is the theme of my test code (and it is my favourite movie). note: this code is "proof of concept" and is exetremely hacked together.
public class Test {
private static HashMap<String, byte[]> barracks = new HashMap<String, byte[]>();
public static void main(String[] args) {
try { new Test().go(); } catch(Exception e) { e.printStackTrace(); }
public void go() throws Exception {
Employee empl = new Employee("Dallas", "Captain");
barracks.put(empl.name, cryogenicallyFreeze(empl));
empl = new Employee("Kane", "Navigator");
barracks.put(empl.name, cryogenicallyFreeze(empl));
empl = new Employee("Ripley", "First Officer");
barracks.put(empl.name, cryogenicallyFreeze(empl));
empl = new Employee("Ash", "Science Officer");
barracks.put(empl.name, cryogenicallyFreeze(empl));
System.out.println("___log file___");System.out.println(".........");
int id = (int) (System.currentTimeMillis() % barracks.size());
System.out.println("[Nostromo]: emergency id #"+id+". Re-animation initiated...");
switch (id) {
case 0: empl = (Employee) reanimate("Dallas"); break;
case 1: empl = (Employee) reanimate("Kane"); break;
case 2: empl = (Employee) reanimate("Ash"); break;
case 3: empl = (Employee) reanimate("Ripley");
System.out.println("[Nostromo]: \"" + empl.name + "\" in command.");
System.out.println("["+empl.name+"]: Hello. I was an object, not a reference, stored in a collection.");
System.out.println();
public static Employee reanimate(String name) throws Exception {
PipedOutputStream pout = new PipedOutputStream();
PipedInputStream pin = new PipedInputStream(pout);
byte[] frozenEmpl = (byte[]) barracks.get(name);
pout.write(frozenEmpl);
ObjectInputStream ois = new ObjectInputStream(pin);
return ((Employee) ois.readObject());
public static byte[] cryogenicallyFreeze(Employee emp) throws Exception {
PipedOutputStream pout = new PipedOutputStream();
PipedInputStream pin = new PipedInputStream(pout);
ObjectOutputStream oos = new ObjectOutputStream(pout);
oos.writeObject(emp);
byte[] frozenEmpl = new byte[pin.available()];
pin.read(frozenEmpl);
return frozenEmpl;
public static class Employee implements Serializable {
String name; String title;
Employee(String n, String t) { name = n; title = t; }
}"inside" of each byte[] object is an "Employee" object? I can't see it any other way. But I am not the sharpest pencil in the drawer...I'm on vacation from coding for a while. maybe i will get it when i start again. thanks.

The size of the file depends how long the application must wait?
hi all
We have build an FLEX application where the user can create an object in SAP. One of the properties of this object is a file.
We had noticed that when the size of the file increases, also the time increases of the processing duration of FLEX to send all data to SAP and to return a succesfull message.
When i set a breakpoint in the ABAP code which is called via a web service by FLEX, it is reached very quickly.
This is the last line of ABAP code and after this SAP has completed its work. So a successmessage returns to FLEX after it
But the time, when FLEX returns this message to the user depends on the size of the file which was send to SAP.
When we send a file of 2 MB it is significant slower then a file of 0,2 MB. And not slower in the traffic SAP - FLEX or the processing in ABAP, but the processing of FLEX after the service call to SAP.
Does anybody have experienced this also? And if so, what can we do about it?
Kind regards,
Anton Pierhagenhmm. i dont think there is any knowledge here about this subject. So i am closing this thread.

File size of corrected jpegs expands to half the size of the original
Using a Canon 1Dx, I have an option of utilizing both slots and assigning different file types to each. In one slot I shoot RAW, and on the 2nd slot I shoot a JPG backup. Typically though I'll do all my work on the RAW file in Lightroom 5. The unimported JPG shot on the second slot expands to approx. 51MB. But the CR2 file, imported to Lightroom 5 and then exported as a corrected JPG, only expands to 28MB. Am I missing something on import/export that would reduce the filesize of the corrected JPG? I cannot find a setting that is toggled that augments import/export size. Is this a bits per channel issue? Similarly, I have the same issue with Bridge. When converting a CR2 file to JPG it expands to the same 28MB filesize. My client wants his JPG to expand closer to that 50MB number.

When the JPG file is opened, it shows as 51MB. When the CR2 file is opened it's 28MB. I was under the mistaken impression that the files would produce equally sized JPGs, and that somehow in the output from Lightroom it was constraining the size of the finished image.
When you say "opened" what 'MB' reading are you reffering to? Lightroom can show the image file's Resolution (5184 x 3456), File Size (MB), and Megapixels. What does LR show for these three reading, in particular you should be interested in the image 'Resolution' value.
When viewed in PS your Canon 1Dx raw image files should show a 'Document Size' of:
5184 x 3456 x 3 (RGB) x 2 (16 bit data) = 107,495,424 Bytes ÷ 1,048,576 (# of Bytes in MB) = 102,515,625 Bytes = 102.5 MB
Your full-size Camera JPEG images should be exactly 1/2 since they are 8bit images = 51.3 MB
I can confirm these numbers with my Canon 600D, which also uses a 5184 x 3456 resolution sensor.
You may have your camera set to shoot M-Raw (3888 x 2592) or S-Raw (2592 x 1728) with full-size JPEG (5184 x 3456). -
What is happening when I change the size of the image in the program sequence window?
I noticed that I can change the image size of my exported file. I imported a 720 x 480 DV file into CS5.5. I went to my program sequence window and changed the settings to show the smallest image in that window. I then clicked on the image and used the handles that appear to make that small image large enough to nearly fill the screen. When I exported my final file and played the resulting WMV, the image on my screen was nearly twice as large as it would have been if I had not previously altered the image size in the program sequence window. I had to do this alteration for each clip in my timeline, or the unaltered ones would stay at the smaller size. The quality did not seem to be significantly impaired. I learned about this on a youtube video. The person who did the video claimed that this was a simple and quick way to upgrade standard video to HD. Of course this is not true. He was only changing the size of the resulting video. Does anyone know what is really happing when you do this procedure and why it changes the size of the exported video?
The size (resolution) of the exported video is not affected by anything you do while editing. It is dependant solely on the resolution set in the export settings.
Ideally you want to edit in an sequence that matches your media\, which will be the same size or larger than the required export. In other words, the same or smaller is OK. Making things bigger in post is not the best option. If you need things bigger, shoot them bigger. -
How to find out the size of a file?
Hi,
I would like to determine the size of a file from my code. How is that possible? I do not find any appropriate method in the java.io.File class.
Any help would be very appreciated!java.io.File.length()
Returns the size of the file as a long. The number corresponds to the number of bytes in the file.
