Simple question about firmware 2.0? Please answer.

Ok I have a macbook air and toshiba laptop and got myself a ipod touch. If I update my ipod touch firmware to 2.0 on macbook air for 13.99 NZ$ do I have to pay another 13.99 NZ$ if I tend to sync my touch with laptop in the future?

Thank you so much
Just one last question? What does authorization do to the computer or music? I have some music I never paid for if you know what I mean. By authorizing will all that music be deleted?

Simple question about sockets and streams - please answer it!

Hi
I have a server socket and a client socket. Both are up and runing. But I'm having problems to send a string from the client and read only the four first bytes on the server. Please read the code and some other comments below:
socket client:
DataOutputStream out =
new DataOutputStream(socket.getOutputStream());
// read from keyboard input
BufferedReader myinput =
new BufferedReader(new InputStreamReader(System.in));
System.out.println("Type any 4 chars and [enter].");
String any = myinput.readLine();
out.writeBytes(any);
out.flush();
server socket:
in = new DataInputStream(socket.getInputStream());
byte[] id = new byte[4];
in.read(id, 0, 4);
System.out.print(new String(id));
According to the code, it should read 4 bytes from the input stream (in.read(id, 0, 4)), but it displays only the first byte. For example, if I type "hello" on client, the serve should show "hell" but it shows just "h"
Any ideias? Thanks!

Hi,
Check the Javadoc for 'in.read(id, 0, 4);' This reads up to 4 bytes and returns the number of bytes read. You need something along the lines of
int count = 0;
while (count < 4)
count += in.read(id, count, 4-count);

A simple question about combo box

Dear All,
Just got a simple question about combo box: I have one of these selectors with labels based on filtered rows from a table.
Is it possible to have one more label that would select all options?
Like:
Product A
Product B
Product C
All Product
Many thanks for your help!
Gilles

Hi Gilles,
The purpose of ComboBox itself to select single option out of many.
For your purpose, you may have to use "List Builder" which can accomodate 1 or more to select.
Please revert for more clarification if you need.
With best wishes

Simple question about mount and delay script

Hello, I have a simple question about mounting volumes on start up.
My computer wakes up auto - and then auto there are serveral applescript tasks (mount and start up programs)
I use this script (daily) for serveral connections with external volumes I always need the connect to. ( In the script I use this code 3 times for other locations) I do this on start up.
set Uname to "XXX"
set Pword to "XXX"
set someVolume to "afp://XXX.XXX.XXX.XXX/XXX/XXX
mount volume someVolume as user name Uname with password Pword
(same code for 2 other locations)
When i do this on start up sometimes the script says there is no connection possible. I guess it's because on start up the connection isn't there. And 1 minute later when computer is total ready the connection is ok. When I run the script then It works. Just sometimes ( In the morning) 'It' want to connect but the script stops. When i do it manually(I run the script again) it works just fine.
Is it possible that I need a delay? Can someone explain this?
How would I make a delay handler for this script? Is that the best solution?
Thanks in advance. This is something small i'm wondering about.
Colin

BTW, If you saved the script as an application +(and not as an application bundle)+ you could drop the script on to *Drop Script Backgrounder* (freeware).
Then the script would run in the background, so, you wouldn't see it running in the Finder.

A simple question about performance!

Hi! I have a simple question about performance. Suppouse that you have a servlet or a class with DB access, and you need to use a value several times in that page. What is best, to assign the value from say, a resultset or a request.getParameter() to a variable or to call the resultset or the request every time you need to retrieve that value? Which option uses less memory, which is faster, etc.?
Hoping the best fou u
Raul

If you need more values from a db, the best is to open some connections (connection pool) and use the for accessing the db.
To get the data only once, open the connection, get the data, store the data whereever you want: variable (class), hidden control (if you want to send from one page to another by request) and close the connection as quicky as possible.
The advantage of the first method is that the most time consuming activity (connections opening) is done only once.

A simple Question about % in CR Chart!

Hi, I have another simple question.
When i use SQL to storage data and wanna Crystal Report to display the data in chart using %
which data type should i use?
float or string?
and I found when i use 0.12 as 12% in database , It could not display in Crystal Report line chart normally.
What should I do??
Please Help!!!
Thank you VERY MUCH!!!

If you have the datatype as string from your database then try adding the string field as a summary field in chart and select maximum instead of count and if you have them in number format then you can directly select the percentage in chart.

Re: add-ons. Just a simple question I couldn't find an answer to. Is the term "uninstall" equivalent to "remove the software from the computer"?

I downloaded a You Tube downloader, and expected an icon to come up when You Tube was playing, according to a friend's advice.
Since this didn't happen I assumed the download didn't work, or was an old version that doesn't work anymore. I wanted to just get rid of it and try another downloader.
I went to Tools--> Add-ons--> and clicked on the downloaded software and saw the 2 options [Disable] and [Uninstall]. The terminology is unclear, as I've always thought once software resides on your computer you can install it or uninstall it without erasing it from the computer.
A simple question that seems obvious except to someone who wants to be very precise and sure. Basically "does [Uninstall] mean erase from the computer"?
Thanks

With Firefox extensions (Tools > Add-ons > Extensions) you have two possibilities. You can disable an extension if you do not want to use it now, but want to keep it. Or you can uninstall an extension and remove it from the computer. Note that uninstalling an extension still leaves prefs in about:config (prefs.js) and possibly files in the profile folder that will be reused in case you decide to reinstall an extension at a later time.

Simple question about flex and AS 3.0

Hi, this might sound like a simple question so I apologize...
I have both a copy of flex 2 and 3, and i want to simply code in AS
3.0 not mxml. I referred to the help of both flex 2 and 3, and all
i could come up with is "you can add dynamic behavior to your
documents using actionscript", which means to me, you only write
your functions in AS and create instances with mxml (...ugh).
personally, i find mxml to be ugly (mainly because it looks like
html to me), and i'd rather not use it. coming from programming in
an IDE in Java, it seems like it would be nicer to have something
similar, all the while having the power and cool features of flash.
I'm not fully educated in this matter so i understand that i could
be totally wrong.
i mean, if i have to code in mxml, i will. i'm a web
programmer for a living, and if a more experience programmer said
something like "if you don't code mxml in flex, you'll never get a
job coding in flex", i would trust the advice, and learn the ugly
code. :)
yes, i do have Flash cs3, it's great but it seems like a pain
to me the way you organize classes.... i've only seen a few
tutorials, ones that explain how you cannot simply import a custom
class, you have tell your movie to link to it, put it in the same
directory, or manually name the package, it's sort of confusing.
my main point here is that i'm very eager to start building
apps in straight AS 3.0 instead of using flash cs3 (for some
projects), and it would be cool to get some help or be pointed in
the right direction.
to simplify:
can i write AS 3.0 and only as 3.0 in flex 2 or 3? how? can
you link me to a tutorial? any advise?
thanks!

Hey William, thanks for the post. It's a great coincidence
because I'm reading that book as well. I'm about half way through
it, and I love it. I installed mxmlc on my linux box and am writing
pure AS 3 apps. I think that's the way to go, though I know it's
not for everybody.
My problem with mxml is that it has a weird syntax for
function calls, and it's not as 'intuitive' for a person like me,
who came from C++ and Java programming in the past. I like writing
programs in the C++ and Java style syntax, and since so many other
languages use a similar syntax, I don't see any reason to learn the
nuances of mxml, unless I was getting paid to do it. As far as I
can tell there is no benefit.
I hate using Flash to write flash apps as well, I feel like
they become messy and confusing, especially when trying to write an
OOP application. I only use it if I want to move an object in a
very specific way and can't do it with the Tween methods.

Simple question about JAVA path

Hi. I have a simple question , but I spent several hours trying to find an answer.
How do I know the location of the java executable which is used by Concurrent Manager.
I already know that running which java under application user will not give me the correct answer

Maybe you can try like this:
     public String getPath(){
          Class cls=getClass();
          String className=cls.getName();
          String packageName=cls.getPackage().getName();
          System.out.println(className);
          System.out.println(packageName);
          String newClassName=className.replaceAll("\\.", "/");
          String resouceName=newClassName+".class";
          System.out.println(resouceName);
          URL url;
          url=cls.getClassLoader().getResource(resouceName);
          String path="";
          path=url.getFile();
          return path;
     }

A very simple question about WF

hi experts
I would like to ask a question about workflow
as u may know there is 'Loop' step in workflow, but I am confused when should I use Loop?
Is this step used for processing internal table? if yes, why shouldn't I create a custom BOR method and pass the entire internal table to the method?
many thanks

hi
loop step for not process the internal table,
this is used to process the some steps repetely until condition True or False.
we have two loop steps is there
WHILE AND UNTIL.

Simple question about telnet and characters

Hi all,
We've installed for the first time a SUN machine. So i think it's for a SUN expert a very simple question.
Normally when i type a special character it will be dispayed like " � " [alt+132]
But when i use a telnet session and i type "alt+132" i get a "d" and not "�".
Does someone know where i must start to find out how this works ?
Thanks you very much.

This is probably related to the locale your server is in. I don't remember the default locale a box is installed in if you don't specify. I think its "C". I use the UTF-8 or en_US.ISO8859-1 locales at home. At work, usually C but sometimes applications may require UTF-8. BEA Weblogic required this for a project a while back. This is defined in /etc/init/tz.

Maybe a simple question about M2T ?

Hi
I record in HDV on the JVC GY 101.
I store on the Focus Enhancements DR HD100 Hard disk recorder.
The footage I have is in HDV 25frames Progressive.
The hard disk stores as m2t file and I seem to need to use Mpeg streamclip to convert for Final Cut Pro HD.
I have a few questions about this.
1) What should i convert to with mpeg streamclip ? mov, dv m2v etc etc
2) What setting should I have on FCP with regards to screen size ? The converted clips are 1280x720. When I choose this setting on the sequence, I end up with small black bars left and right of the video on the canvas ???
3) I will also later have to add some digi beta footage which will be PAL, 720x576 Anamorphic.
4) What is the best resolution for me here ?
5) And will the quality of the original m2t file be downgraded by the mpeg streamclip ?
Thanks so much for your help
All the best
Simon

HDV isn't an "edit-friendly" format, meaning: HDV uses inter-frame compression, combined with a long group-of-pictures (GOP) of 15 frames (12 frames in PAL-equivalent). In intra-frame compression (as in DV, DVCPRO HD, etc.), each video frame is a complete image that stands alone. Inter-frame compression (which is also used in DVDs) uses only a limited number of complete image frames, the GOP determines that number. So, in HDV for example, with a GOP of 15 frames, 1 second of 30fps video contains only 2 complete frames, while the other 28 frames are determined by calculations used in conjunction with the Bi-directional ('B') and Predicted ('P') frames, which contain partial information on the changes in the video in between the 'I' frames which contain whole images. This process, of course, requires much more computer processing power than when editing DV, DVCPRO HD, Uncompressed, etc.
Editing video streams such as HDV (and XDCAM HD) is made difficult by the reduced number of I-frames. For example, if you make a cut in between the I-frames in the video clip, the computer has to then recalculate new I-frames that are placed at both sides of the cut. Converting on capture/after import to an intra-frame codec like DVCPRO HD, ProRes 422, or Uncompressed will reduce processing power and increase real-time performance, as well as give better performance when adding effects and performing compositing like chroma-keying.
A common rule of thumb in professional applications is to acquire in HDV, XDCAM HD, etc., but capture and edit in DVCPRO HD, ProRes 422, or even Uncompressed. Native HDV editing is not taboo by any means; it's just not as easy or robust -- especially with the LONG render times. Depending on what kind of work you do (and of course personal preference), you may not see much benefit by transcoding to another format.
Are you suggesting i have to convert each clip after capture?
Unless you have an HDV deck with HD-SDI and a capture card, you would have to convert each clip. Batch-conversion would be very useful for that.
Hope that helps.

A simple question about DAQ data sampling

Hi all:
Now I meet a very basic question about DAQ sampling. I am using NI PCI-6040E DAQ card, SCXI-1001 chasis, SCXI-1102, SCXI1300 terminal block, and SCXI1160 relay module.
I am not sure , is it possible if I want to test a voltage (1 volt) on a resistor. Now I am connecting the Ch0+ to resistor+ (24 volt), and connecting Ch0- to resistor-(23 volt). So the voltage between resistor+ and resistor- should be 1volt. Actually, It is working at the first, but after I want to test 9 channels based on this connection. The Measurement & Automation can't read data from the DAQ card. (when I test it by multimeter, I can get the voltage data on the Ch0+ and Ch0- of SCXI1300 terminal block).
That's strange, does anybody know what' s wrong about it?/
Thanks a lot

Hi hanwei,
According to the specifications of the PCI 6040E (page 3), the input signal and common mode voltage should never exceed 11V from ground. I believe this is the reason you are able to measure the potential of a battery but not the 24V signal (even though the differential value is only 1V).

Question about inner class - help please

hi all
i have a question about the inner class. i need to create some kind of object inside a process class. the reason for the creation of object is because i need to get some values from database and store them in an array:
name, value, indexNum, flag
i need to create an array of objects to hold those values and do some process in the process class. the object is only for the process class that contains it. i am not really certain how to create this inner class. i tried it with the following:
public class process{
class MyObject{}
List l = new ArrayList();
l.add(new MyObject(....));
or should i create the object as static? what is the benifit of creating this way or static way? thanks for you help.

for this case, i do need to create a new instance of
this MyObject each time the process is running with a
new message - xml. but i will be dealing with the case
where i will need a static object to hold some
property values for all the instances. so i suppose i
will be using static inner class for that case.The two situations are not the same. You know the difference between instance variables and static variables, of course (although you make the usual sloppy error and call them static objects). But the meaning of "static" in the definition of an inner class is this: if you don't declare an inner class static, then an instance of that inner class must belong to an instance of its containing class. If you do declare the inner class static, then an instance of the inner class can exist on its own without any corresponding instance of the containing class. Obviously this has nothing to do with the meaning of "static" with respect to variables.
