• How to read the data in a device connected to the usb port

  Is there a class or object, or the piece of code in Java that is comparable to the PDQComm32.ocx and the mscomm32.ocx used in VB6? I need to know how to read the data of a device plugged into the usb port of the BBerry. Is it possible to use the BB to read data from a device via a usb cable?

  I'm new in Java and I'm looking for the opportunity to write a project to read the data in a device with this program that can turn on a BB instead of on a pc.

  Thank you

  Did you watch net.rim.device.api.system.USBPort?

  That's what the doc says:

  Provides access to the USB port of the device.

  Avoid using this class in applications, as it is not portable. On the contrary, if you need to access the USB port, use factory CLDC Connector to serve a connection.

• How to read the data with different XML schemas within the unique connection?

  • I have Oracle database 11g
  • I access it via JDBC: Slim, version 11.2.0.3, same as xdb.
  • I have several tables, each has an XMLType column, all based on patterns.
  • There are three XML schemas different registered in the DB
  • Maybe I need to read the XML data in multiple tables.
  • If all the XMLTypes have the same XML schema, there is no problem,
  • If patterns are different, the second reading will throw BindXMLException.
  • If I reset the connection between the readings of the XMLType column with different schemas, it works.

  The question is: How can I configure the driver, or the connection to be able to read the data with different XML schemas without resetting the connection (which is expensive).

  Code to get data from XMLType is the implementation of case study:

   1   ResultSet resultSet = statement.executeQuery( sql ) ; 
   2   String result = null ; 
   3    while(resultSet.next()) { 
   4   SQLXML sqlxml = resultSet.getSQLXML(1) ; 
   5   result = sqlxml.getString() ; 
   6   sqlxml.free(); 
   7   } 
   8   resultSet.close(); 
   9    return result ; 
  

  It turns out, that I needed to serialize the XML on the server and read it as BLOB. Like this:

   1    final Statement statement = connection.createStatement() ;  2    final String sql = String.format("select xmlserialize(content xml_content_column as blob encoding 'UTF-8') from %s where key='%s'", table, key ) ;  3   ResultSet resultSet = statement.executeQuery( sql ) ;  4   String result = null ;  5    while(resultSet.next()) {  6   Blob blob = resultSet.getBlob( 1 );  7   InputStream inputStream = blob.getBinaryStream();  8   result = new Scanner( inputStream ).useDelimiter( "\\A" ).next();  9   inputStream.close(); 10   blob.free(); 11   } 12   resultSet.close(); 13   statement.close(); 14  15   System.out.println( result ); 16    return result ; 17
  

  Then it works. Still, can't get it work with XMLType in resultset. On the customer XML unwrapping explodes trying to pass to another XML schema. JDBC/XDB problem?

  Hello

  First, you must open a ticket with oracle Support and explore the options

  You can use this note to fix:
  RECOVERY OF A LOST IN A [ID 1013221.6] UNDO TABLESPACE DATA FILE

  If you are unable to drop Undo tablespace as Undo Segment recovery must

  You can download the trace file following the opening of the ticket

  SQL>Alter session set tracefile_identifier='corrupt';
  
  SQL>Alter system dump undo header "";
  
  Go to udump
  
  ls -lrt *corrupt*
  
  Upload this trace file
  
  Also upload the alert log file
  

  Kind regards

• How to read the date of the day of the day of the year?

  I want to put 30 days for the test of endurance for the application of the components. the user will have the current value of 30 days with specify them the end of the day.

  I saw that the "seconds to Date/Time.vi" sure I checked the day of the year. If I can use this day of the year, I can add + 30 read 30 date.

  Barros,

  What I gave was the answer you were looking for originally because I believe.  You will not just be able to read the date in a coherent way and then add 30.  You can either use the function Get time in seconds or a few varaint it and then add the offset you want (you could use the get a Date/time string and enter the date directly, but this digital conversion which will be useful in the monitoring of the time elapsed will be much more difficult than what I provided only).  If you want to stop the test, simply to keep track of the amount of time the test is in pause and extension at the time where that amount.

  Cheers, Matt

• How to read the data written to the virtual disk

  I use the following VDDK function to read the Flash disk from VMware

  http://bigchainring.kicks-ass.NET/functions/VixDiskLib_Read.html

  But areas of complete disc playback, including empty spaces. I need to back up only the data written to the Flash disk. It is to save the backup disk space (for example if 126 instant KB is written in 40 GB of disk snapshot, then we read only 126 KB and not 40 GB drive). Please suggest the correct way to read the data written to the Flash disk as well as to reproduce the same virtual disk with the data.

  VMware vSphere API queryChangedDiskAreas() can be used to obtain the data blocks in the virtual disk.

  Steps to follow:

  1. get the beaches of block of data (numbers) using queryChangedDiskAreas() API with '*' as argument.

  2 read the data of the specific blocks by using VixDiskLib_Read()

  3. write to another drive using VixDiskLib_Write()

• OSB: How to read the xml file, which is in OSB project

  Hello
  
  We have a generic proxy (PG1) reporting and deals alerts, this proxy is called in the pipelines of proxies anothers (P1... PN) in several projects. Each client proxy (P1... PN) PN) before call proxy PG1, configures a variable with syntactic alert or report.
  
  We thought it would be a good idea to store the specifications for all the proxies of a project as an xml file, so that the proxy PG could read the xml file. This file will be in the OSB project.
  
  The questions are:
  -proxy can read a xml file that is in the OSB project?
  S ' Please, are all the documentation for this?
  
  Thank you
  
  Kind regards

  You can always do customization to work with the properties defined in a XML xquery. The key to this is to use the customization of reference instead of find and replace the customization, similar to the service account customizations.
  Keep your real estate to as properties_dev of env xquery specific xmls, properties_sit etc then apply customization of service proxy xquery reference reference specific correct env.

• How to read the txt file that has words in between?

  Hi all

  I'm using Labview 8.2.

  I would like to read a text file.  I have given (after whenever he was on average more than 100 waveforms) several times recorded on the file.  The idea is to further improve the SNR in post processing by averaging once again the data (which was on average about 100 wave forms).

  I can get LabView to save the data in the file several times, then it keeps joins.

  The problem is to read data from labview, so I can on average now again.  The problem is the labview separates data sets with the following:

  "Channel 1".
  9925 samples
  Date 28/10/2008
  Time 17:16:11.638363
  X_Dimension time
  X 0 - 3.0125000000000013E - 3
  Delta_X 2.500000E - 6
  "End_of_Header."

  Then when I read it, he sees only the first set of data.

  Can someone tell me please how to read all the datasets under labview?

  I am attaching the file I want to read 'acquiredwaveform.txt' and the VI base (really basic btw) to play the file.

  Thank you

  This seems to be a standard LVM-file.  You can read segments of different data using the VI Express LVM loop (make sure that the file retains its extension .lvm).  I modified your example to show this.

  Note that my example is quite inefficient. Table of primitive construction causes a massive memory copy whenever it is used, and you would be probably better on average that you read in.  I made this way to make it more obvious how read segments of a file LVM.  In the process, I noticed that you have a good amount of phase jitter (zoom in on the graph of all the three waveforms).  With an average simple will make you smear on your waveforms.  You can either fix the problem in hardware (recommended) or phase shift your data so it lines up before on average.  If you need help with it, let us know.
