• How can I read only text files in a directory.

  I wrote a program to play the files in a directory, but I want to let him read the text files from the directory.

  import java. IO;

  public class {data}

  Public Shared Sub main (String [] args) throws IOException {}

  String target_dir = "C:\\files";

  File dir = new File (target_dir);

  File files [] = dir.listFiles ();

  for (file textfiles: files) {}

  If (textfiles.isFile ()) {}

  InputStream BufferedReader = null;

  try {}

  inputStream = new BufferedReader (new FileReader (textfiles));

  String line;

  While ((line = inputStream.readLine ())! = null) {}

  System.out.println (Line);

  }

  } {Finally

  If (inputStream! = null) {}

  inputStream.close ();

  }

  }

  }

  }

  }

  }

  You mentioned you want to only read text files.

  If you are referring to a specific set of extensions, you can filter on this basis.

  ex: you want to only read .txt files, you can add an if condition as below:

            if(textfiles.getName().endsWith(".txt")) {
                // Add your code here
            }

• Read-only - user files - can't change for write access

  In the users (only one user) section all the folders are read-only. I'm moving to the music in my music file, but it won't let me. I get an error indicating that this action requires administrator rights, the diolgue box Monte 'do you want to get permission for this action', click Yes, and then he says denied action! What happens - I have not had this problem before.

  I followed the cmd prompt 'attrib-r + s C:\Users\Mel and Steve\Music' and other combinates, but it wouldn't let me make changes.

  Help, please!

  Windows Vista

  This sounds like a permission problem.  When I came across a similar problem with Vista, I installed a registry patch that adds a' Take Ownership"option in the context menu to reset the permissions on the files."  Simply right click on a folder you are the difficulties to access to the, (IE C:\Users\YourUserName) and then click "Take Ownership" allows you to access these folders and all subfolders beneath it read/write. This is what solved my problems:

• Why does not define RMAN bkp merge data files and the archivelogs in a single bkp

  Why not RMAN backup data files (fusion) handset and the archivelogs in a single backupset?
  
  Published by: Y.Ramlet on April 15, 2013 07:15
  
  Changed the subject line to clarity

  What would be the advantage?

  ArchiveLogs must be independent of the specific database backups. ArchiveLogs can be used for the review (RECOVER) a database to a point in time beyond the backup database. Can I get L0 data backups once a week and backups of databases L1 on a daily basis with the ArchiveLogs daily. The ArchiveLogs should not be bound to the L0, or L1 backups but be useful to RECOVER the database to any point in time.

• Read only data with replication SAN HP store? (CA)

  Hello

  Not sure it should be in the ESX or VC forum...    We use EVA and replication on XP SAN with SAN CA (Continuous Access). We have virtual machines on a LUN (read, write) replicated to a destination LUN Dr. When you use HP CA it marks the destination LUN read-only source...

  We want to import the LUN target in our cluster of DR esx, but when we add the disk it formats... We have tried to deceive esx by adding the data reading writing that works then set up this store again which marks while reading then however only store data disappears from the host to storage page...

  Anyone know if this will work or how to make it work?  Maybe a setting advanced on the part of the drive to ESX import read only LUNS which we will turn to read write if we talk about DR

  Any ideas would be thank you very much

  Packetboy.

  On the second site ESXs, enter into the advanced settings and go to LVM > DissalowSnapshotLun and set it to 0. Perform a new analysis and data warehouses SHOULD appear available. You can go back to la to write.

  Only, I did not understand why the added ESX your LUN as data stores format again. This behavior should not happen. Maybe something is not replicated.

  Do not forget that, by adding a virtual computer, you will need to keep/change the uuid as the data store has changed unit logic (indeed) number.

• Reading excel data file in Oracle form data blocks

  Hi all
  
  I want to read the data from the excel file in the data block of the module of the form. There are many resources available that explain how to put the data in oracle forms in the excel sheet, but I can't find a single resource to achieve this functionality. Can someone please help me get around this problem. Any help will be much appreciated.
  
  Thanks in advance
  Bilal

  Bilal,.
  There is little documentation available through My Oracle Support, which shows how to read an Excel file in a form, but you need a support contract with Oracle to access the document (how to read data from an EXCEL worksheet in a form using WebUtil Client_OLE2 [813535.1 ID]).

  I've seen this issue come up in the forum from time to time, so I wrote a small form demo which illustrates playback in Excel in a form. Discover forms: how to read an Excel file in a form. This demonstration uses the WebUtil library, so you must make sure have WebUtil correctly configured in the Forms Designer, as well as on your application server.

  Hope this helps,
  Craig B-)

• Read-only data objects

  What is the best way to ensure that the data in the cache is not changed once it is placed in the cache? Is there a way to specify that objects are 'read only '?
  
  My cache clients must have the ability to read and write to and from the cache, but should not be able to change (or replace) the existing entries. They should just be able to read existing entries or add new unique entries.
  
  Thank you!

  Hello

  You should be able to extend WrapperNamedCacheto get the desired behavior.

  A close example of what you want to do is ReadonlyNamedCache

  Thank you

• Tabular read only Date Picker

  Hello
  I have two or three items with dates selectors and do not want to implement
  This code because it will be too many buttons on my form. I need to delete an element
  at a time when the date picker is read-only, but in tabular form.

  function f_clear_items()
  { 
      {$x('P1_ITEMA').value = ''};
      {$x('P1_ITEMB').value = ''};
      }

  Then after that I created a button url and pass this function I can erase the datepicker. But, I
  has been wondering is there a cleaner way to do this.
  
  I have other items on the page that are the same name but in different tables. I only want
  to clear each item date picker at the same time. This code works very well for a regular shape.
  -Item after item to erase text element

  a href="javascript:setValue('P1_ITEMA','');">Clear Date</a

  There is a named thread "how to delete a page only reading point...?" that shows how this code works, but does not work
  work for a table shape in a page master detail. There is a link on the side of the switch of dates to delete the item specified, but in a tabular form point, there is no tab of the item, any ideas on how to clear a date picker component readonly by using a tabular form
  and not with a button for each item, thanks in advance. I use the Application Express 3.2.0.00.27.

• Reading input data file

  Dear all,

  I wonder if someone helps me.

  I have a labview program which I am using right now. At this point, I need to read an input (dat or txt or excel) file in real time.

  for example, here's my data entry (2 columns and 5 rows):

  1.2 2.2

  2.3 2.3

  3.05 3.3

  4.3 4.4

  5.2 5.5

  for example in evry second I want to read a jut line and do the math. in this way, in real time, I can read each line one by one.

  How can I do?

  Kind regards

  Mehdi

  For the text, simply use the reading of spreadsheet. Take exit 2D and wire of a loop for. put a wait of 1 second inside the loop and you are finished.

• Simulation read data file (*.) (DAT) by using the worksheet (file reading eror - zeros)

  Dear OR community,

  IM pretty new in LabVIEW, so I have a few broblems with reading the data.

  I take a screenshot and mark a problem like part - A and part b below:

  

  The description of the goal:

  I do a mathematical simulation, using the old software whitch exporting results as shown in 1... DAT file, as it shown in the picture (Notepad).

  First of all I need not read these data then I need to draw the graph XY.

  Description of the problem:

  I created a LabVIEW program and im using a funciont reading of spreadsheet per section B - but when im trying to read data im getting all zeros...

  so I can't identify my problem... What is the problem?

  I try different file to read its Case_test_working.txt and everything is good with this data but when im trying to read *. DAT file zeros is array...

  I tried to use seperator different symbols, also try to imort data to exel then export to *.scv, *.txt formats, but the performance was the same as that indicated in part-A.

  Whenever I get zeros, but not a results as in *. DAT or another file format exported with the same data.

  Please be respectifull and understand that im still newbie in labview but I think its excellent software of filtering of the analysis of data and calculations, so I want to master this software for my future use.

  Respectfully,.

  Here's a (big) hint.

  

  I would like to give you an excerpt, but I've not updated this machine yet.  It's a pretty boring delimiter, if you know what's good for you, you start to use commas, tabs or simple spaces (my order of preference).  It is far too easy start add or remove spaces and then you need to use more complex methods to obtain data from worksheet.
