How to read input from handheld scanner on a keyboard port

Hi everybody,
i have an application that should read input from a scanner.
If i use a jTextField to input scanned data it works fine.
the problem is that i don't want to use any text component to input data into it.
And if i set the jtextField not visible then the focus sustem doesnt work.
I tried to read a buffered input stream from System.in but it doesnt work.
If the scanner was installed on a serial port i could use javax.comm to monitor it.
But unfortunately i must use the keyboard wedge thing...
Do you have any ideas?
Thank you in advance

BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()))
null

How to read input from a file that is constantly being appended to?

Hi -
My problem is simple, yet very difficult to solve. There is a log file I want to read through, that is actively being written to by another program. I want to be able to block at the eof for more input, much like a network stream can block for more input. However, nothing works.
Here is my snippet so far:
            int ch = '0';
            while( !terminate ) {
                while( (char)ch != ']' ) {
                    ch = isr.read();
                    System.out.print((char)ch);
                System.out.print("\n");
            }Terminate is just a control variable. isr is an InputStreamReader.
The way the log file works is, the end of each line is denoted by a closing box-bracket. So I figured checking for that would be easy enough. The problem with that loop is, it keeps causing my IDE to hang when it runs... It will output the log file contents, but repeatedly, infinite times. I thought the read() method blocks when there is no more input?
Is there anything else I can do to capture new appended text to this file?
I've tried InputStreamReaders and FileInputStreams as well, and they all do the same thing.
Thanks!

Yes, I more or less do this. Now I simply open the BufferedReader a few bytes short of the file size (to save on memory usage) and then keep the buffer open. Then I just have the thread sleep for 500ms to not throttle the CPU through the roof. Then I merely check if the buffer does not equal null, if it doesn't, that means there is more stuff to process.
I figure half a second delay maximum is practically realtime, and it is improv enough to do what I need to do.
Thanks for the help.

Read Input from console !!!

Im am very new to java and trying to learn java ..
Now the problem i have is, I have to read input from console without using the BufferReader method..
Please tell me how to go about it..
I have a assignment to complete and im not able to figure out the way out.
Help ..

http://java.sun.com/j2se/1.4.1/docs/api/java/lang/System.html
Read first about the System class provided by Java.
Select the 'in' method of System class and it will take
you to the InputStream.
http://java.sun.com/j2se/1.4.1/docs/api/java/io/InputStream.html
An essay way of reading input is:
"value?"=System.in.read();
Try and see if this works. It will not use the
BufferReader portion, but it gives you another way
of reading from the console.

Make System.in read input from a command prompt

How can i make System.in read input from a command prompt which is opened after program
is started. Please note that program starts without commad promt. Can u plz help?
sharmila

System.in DOES read from the command shell that you start the app in.
What you don't have is a prompt.
You should know about Java Almanac. There are code samples for simple things like I/O that everyone should know about. There's an example there to help you.

RPJ,
You do not need to use the Close Zip File.vi when you unzip a folder. This VI is used when you are creating a zip folder.
As for examples, I found a couple of ActiveX based MS Access examples. These programs look to be pretty basic. For more in depth example I would search Microsoft Developers Network

How to read data from an internal table into a real table?

Hello experts,
I'm relatively new to ABAP and I'm trying to figure out how to read data from an internal table into a table that I created. I'm trying to use the RRW3_GET_QUERY_VIEW_DATA function module to read data from a multiprovider. I'm trying to read data from the e_cell_data and e_axis_data tables into a table that I've already created. Please see code below.
TABLES MULTITAB.
DATA:
query_name TYPE RSZCOMPID,
s_cubename TYPE RSINFOPROV,
t_cell_data TYPE RRWS_T_CELL,
t_axis_data TYPE RRWS_THX_AXIS_DATA,
t_axis_info TYPE RRWS_THX_AXIS_INFO,
wa_t_cell_data like line of t_cell_data,
wa_t_axis_data like line of t_axis_data,
w_corp_tab like line of t_cell_data.
s_cubename = 'CORP_MPO1'.
query_name = 'Z_corp_test'.
    CALL FUNCTION 'RRW3_GET_QUERY_VIEW_DATA'
       EXPORTING
         i_infoprovider           = s_cubename
         i_query                  = query_name
        i_t_parameter            = query_string_tab
       IMPORTING
         e_cell_data              = t_cell_data
         e_axis_data              = t_axis_data
         e_axis_info              = t_axis_info.
If anyone has any information to help me, I would greatly appreciate it. Thanks.

Hi,
<li>Once you call the function module RRW3_GET_QUERY_VIEW_DATA, lets say data is available in the corresponding tables e_cell_data e_axis_data which you have mentioned.
<li>Modify your internal table defined for other purpose, with data from e_cell_data e_axis_data like below.
LOOP AT t_cell_data INTO wa_t_cell_data.
"Get the required data from t_cell_data.
MOVE-CORRESPONDING wa_t_cell_data TO it_ur_tab.
"Modify your internal table wih data
MODIFY it_ur_tab TRANSPORTING <field1> <field2> <field3>.
ENDLOOP.
LOOP AT t_axis_data INTO wa_t_axis_data.
"Get the required data from t_cell_data.
MOVE-CORRESPONDING wa_t_axis_data TO it_ur_tab.
"Modify your internal table wih data
MODIFY it_ur_tab TRANSPORTING <field1> <field2> <field3>.
ENDLOOP.
Thanks

Help me how to read the Hyperlinks from the PDF file using java ...
Thanks in advance,
With Regards,

Instead of cross-posting unformatted code you could have taken a look at the API, because there you might have come across a method named getLinks...Even though it's not documented, I really suspect that it will return the Hyperlinks on a given page.

How to read values from DMM4040

Hi,
I am using DMM4040, NI PXI 6509 device.
I need to make some port pins high which i have already done and now i have to read value captured by DMM then i have to make my port pins low if my value is within limits.
Can u suggest me how to read values from DMM and then by notification i ll make my port pins low.
'' A professional is someone who can do his best work when he doesn't feel like it''...........

What language are you using? If using LabVIEW, you use the NI-DMM API to communicate with the 4040. Just take your reading, do your limit comparison, and set your lines based on the comparison results.
