How to transfer the content in a StringBuffer into a InputStream

I need append the comment to the buttom of each file. I read the file into the stringbuffer first, appending the comments. After completed, how can I send the content in the StringBuffer back into a InputString in order to continue with some other file manipulation?
I saw a method StringBuffer.toString(), but nothing to transfer back to InputString
Thank you in advance

How aboutnew StringReader(sb.toString());Since you are working with text data, you should be working with Readers instead of InputStreams.
(And if you are appending data to a file, wouldn't it be more effective to just use the version of FileWriter that allows you to append the data, instead of reading the whole file and writing the updated file back?)

How to transfer the content of the video to Adobe Premiere Pro CS3 for editing ?

Hi there,
I have an old video camera that is still working. That video camera uses a Hi 8 tape. The tape is bigger that the current DV tape. The size of the tape is something like a tape cassette.
How to transfer the content of the video to Adobe Premiere Pro CS3 for editing ? Being an old video camera, the output doesn't have any firewire or USB connector. In fact the only output is has is the Yellow, Red & while connector (is this referred to as composite).
So, how do I input this Yellow, Red & White cable into the PC (or rather into Adobe Pro CS3) ?
Any established hardware/convertor to recommend ?
Thanks

Ryan,
For "composite out," only you will need an A-D "bridge" to Capture from that camera. Grass Valley/Canopus offers two really good ones, the ADVC-110 and the ADVC-300. There are others and also PCI A-D capture cards, but the Canopus units get very good reviews.
One other workflow would be to hook your older camera to a digital video camera with passthrough (not all have this and it is being discontinued fairly rapidly in consumer cameras) and then doing the Capture through that digital video camera via FireWire. You will not have Device Control, but can easily start/stop via the mouse and one hand on the switches, or on a remote.
Good luck,
Hunt

I am thinking of buying a MacBook Air and am wondering how to get the content of my iPad into iTunes.

I have iTunes on an old pc and am thinking of buying a MacBook Air. I am wondering how to get the content of my iPad on to the Mac as I know that sync only happens in one direction, from pc to device. I assume therefore that when I attach my pad to the new Mac it will sync to an empty iTunes and I will have lost all the content of my pad. I know I can restore purchases, but what about contacts, calendar, photos and music not purchased from apple. I have a fairly recent backup on a pen drive but it is a usb2 device and is formatted for a pc. Any advice would be appreciated.

Do I copy my media library or from a backup. I have a backup on my pc and on an external drive. This drive is usb2 and formatted for windows so I can't connect it to a MacBook Air to make the transfer. Equally I don't think there is a way to connect the 2 computers via a cable ie usb2 one end and usb3 the other. Will the computers talk to each other via wifi if I enable home share although I think this is only for music which still leaves contacts, mail etc.
I am sorry to be such an ignoramus but any further help would be appreciated.

HI,
Take for example, if Excel file contains 4 fields,
Add jxl.jar to JavaBuild path and Use this snippet
File f=new File("sample.xls");
Workbook w=Workbook.getWorkbook(f);
Sheet sh=w.getSheet(0);
int cols=sh.getColumns();
int rows=sh.getRows();
Cell c=null;
String s1=null;
String s2=null;
String s3=null;
String s4=null;

How to transfer the contents of a line of a table control to second screen?

Hi,
I have a table control and I have entered some contents in one line of a table control .
When i click on this line and then click on the detail button on the screen , it should take me to another screen and whatever I have entered in the table control should be transferred to the second screen .
Please could anyone help me out with this .
Regards,
Sushanth H.S.

Hi
U need to get the index of the line of table control by command GET CURSOR:
PROCESS PAI.
LOOP AT ITAB.
   MODULE GET_CURSOR.
   MODULE MODIFY_ITAB.
ENDLOOP.
MODULE USER_COMMAND.
Module to pick up the selected line:
MODULE GET_CURSOR.
GET CURSOR LINE VN_LINE.
ENDMODULE.
Module to transfer the data from table control to internal table:
MODULE MODIFY_ITAB.
ITAB-FIELD1 = <FIELD OF TABLE CONTROL>.
MODIFY ITAB INDEX <TABLE CONTROL>-CURRENT_LINE.
ENDMODULE.
U should considere the variable line has the value of the index of the line of table control, so u need to calculate the number of the corresponding line of internal table:
MODULE USER_COMMAND.
CASE OK_CODE.
    WHEN 'DETAIL'.
* Calculate the line of internal table:
       VN_LINE = <TABLE CONTROL>-TOP_LINE + VN_LINE - 1.
* Read the data
       READ TABLE ITAB INDEX VN_LINE.
* Transfer the data to the output structure of the new screen
       <STRUCTURE>-FIELD1 = ITAB-FIELD1.
* Call the new screen
       SET SCREEN <NEW SCREEN>.
       LEAVE SCREEN.

Hi, Senthil.
This Forum is not a general discussion forum.
You don't believe that the InDesign SDK is a general purpose API. Do you?
I think you must post issues like this where they belong, in this case in a Microsoft Word Forum.

How to Convert the content in BLOB field into a PDF file...

I want to retrieve the files back and store them in hard disk. I am successful in storing the content as a file with '.doc' but if I store the file as '.pdf', adobe fails to open the file with error

You can't convert binary data into character based data.
So very likely this is your problem.

How to transfer the readings from a multimeter into a PDA?

Which are the different ways to transfer the current and voltage readings to an Excel file in a PDA using LabvIEW PDA module 8.0?
Which PDA must i buy? what must be the specs?
which multimeter should i buy? what must be the specs?
Can anyone help me?

Hello Anu,
There are different hardware options that you have here. The basic things that you need to keep in mind is that the PDA that you purchase runs on Pocket PC and has either a CompactFlash or a PCMCIA slot in it. The driver that you would be using for your LabVIEW PDA application would NI-DAQmx Base Ver 2.0.1. You can refer to its readme for more information on the supported hardware. Also you can check at this page for more information on the supported devices. About your original question, using LabVIEW PDA you can create a text file for storing data and separate the data points with a comma. So that this way you would be able to open the file in Excel if you wanted to. All the file I/O related VIs can be found in the function palette at Programming >> File I/O.

How to copy the content of one file into another

I have tried this code
try {
               fin = new FileInputStream("file path");
          catch(FileNotFoundException exc)
               System.out.println("File not found");
               return 0;
          catch(ArrayIndexOutOfBoundsException exc)
               System.out.println("Usage: Showfile file");
               return 0;
          while(true){
               i=fin.read();
               if(i==-1)
                    break;
               cnt++;
          fin.close();*/
now in this way i can lift one character at a time and copy it into another file (note i have not done the copy part in this code but that can be implemented) however this whole procedure is taking too much time if the size of the file is too big....kindly suggest another way to copy one file into another

have you ever copied and pasted a large file in Windows or another OS? Larger files take more time to copy, that's just how it is.

How to save the data of ABAP report into a notepad in desktop location???

HI all,
Can any one tell me how to transfer the data of ABAP report into a Notepad.
Actually I have to schedule a ABAP report in background on daily basis and I want to transfer the
whole record into Notepad.
If any program is available for this..please clearify the relevent code for transferring.
Thanks
Rajeev

declare a character type internal table.
now move your data from it_data ( internal table with data ) into table itab.
since you are running this report in background, you cannot save it to the desktop. Instead give any app server location
data: itab(400) occurs 0 with header line.
field-symbols: <fs1> type any.
data: gv_file type rlgrap-filename default 'TEST.TXT'.
data: gv_filepath type rlgrap-filename default <path>.
LOOP AT it_data.
    DO 100 TIMES.
      ASSIGN COMPONENT sy-index OF STRUCTURE it_data TO <fs1>.
      IF sy-subrc = 0.
        CONCATENATE itab <fs1> INTO itab SEPARATED BY ' '.
      ELSE.
        EXIT.
      ENDIF.
    ENDDO.
    SHIFT itab LEFT DELETING LEADING ' '.
    APPEND itab.
    CLEAR itab.
ENDLOOP.
concatenate gv_filepath '/' gv_file into gv_file.
OPEN DATASET gv_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.
IF sy-subrc = 0.
    LOOP AT itab.
      TRANSFER itab TO gv_file.
    ENDLOOP.
    CLOSE DATASET gv_file.
ENDIF.

How do you transfer the content from an iPhone to a PC? I have to use a PC for a while and don't know how to put my stuff on to there from my phone

How do you transfer the content from an iPhone to a PC? I have to use a PC for a while and don't know how to put my stuff on to there from my phone

If you're talking about music and movies an i-device was not designed for unique storage of media. It is not a backup device and media transfer was planned with you maintaining a master copy of your media on a computer which is itself properly backed up against loss. Syncing music and movies is one way, computer to device, updating the device content to the content on the computer, not updating or restoring content on a computer. The exception is iTunes Store purchases which can be transferred from a device to a computer.
iTunes Store: Transferring purchases from your iOS device or iPod to a computer - http://support.apple.com/kb/HT1848 - only purchases from iTunes Store
For transferring other items from an i-device to a computer you will have to use third party commercial software. See this document by turingtest2: Recovering your iTunes library from your iPod or iOS device - https://discussions.apple.com/docs/DOC-3991

Help me...How to read the content if "Transfer-Encoding:chunked" is used?

I am doing a project for internet control using Java,PHP and MySql.All sites should go through the proxy server only.If the HTTP header contains Content-Length,am getting the content length as below:
public class HTTPResponseReader extends HTTPMessageReader
    String statusCode;
    public HTTPResponseReader(InputStream istream) throws IOException,                     NoSuchElementException
BufferedInputStream distream = new BufferedInputStream(istream);
retrieveHeader(distream);
StringTokenizer st = new StringTokenizer(new String(HTTPMessageReader.toArray(header)));
versionProtocol = st.nextToken();
statusCode = st.nextToken();
String s;
while (st.hasMoreTokens())
        s = st.nextToken();
        if (s.equals("Transfer-Encoding:"))
       transferEncoding = new String(st.nextToken());
     if (s.equals("Content-Length:"))
       contentLength = Integer.parseInt(st.nextToken());
     if (s.equals("Connection:"))
      connection = new String(st.nextToken());
      if (connection.equals("keep-alive")) mustCloseConnection = false;
   retrieveBody(distream);
}After getting the Content-Length,i used read method to read the content upto that content length.Then i concatenated the HTTP header and body and the requested site was opened.But some sites dont have Content-Length.Instead of that,Transfer-Encoding is used.I got the HTTP Response header as "Transfer-Encoding:chunked" for some sites.If this encoding is used how to get the length of the message body and how to read the content.
Can anybody help me.
Thanks in advance...

Why don't you use HttpUrlConnection class to retrieve data from HTTP server? This class already supports chunked encoding...
If you want to do anything by yourself then you need to read HTTP RFC and find all required information. Well in two words you may reject advanced encoding by specifying HTTP 1.0 in your request or download chunked answer manually. Read RFC anyway :)
