Extracting from a file

//this line not working, why?
1.) BufferedReader in = new BufferedReader(new FileReader("icecream.txt"));
//this works
2.) UniReader in = new UniReader("icecream.txt");
// both the lines try to do the same thing right?

Listen, you fool. I just didn't want to post the whole
thing and make the thread big.
I've tried method given in that link.So it worked? Then what's your problem?
I just want to know the conditions in which
BufferedReader is unable to give desired output.Let's see:
1. When you code it incorrectly.
2. When the file path can't be resolved.
Those are a start.
I knew that people can figure out what "UniReader" is, so I didn't give the details about what it is.So why are you asking for the difference between the two if you know so much?
Now stop taunting and act rationally, before you make anyone else unstable.Careful, Robocop. You can already see what happens when you act like this in a public place. You'll find answers hard to come by. Reconsider your behavior for your own good.
Have a nice day.

Extracted from data files

Hello All,
DB version: 9i Rel 2
Which Oracle command line tools allow data to be extracted from data files that are NOT ATTACHED to a database?
DN

Oracle Support has a tool called DUL, Data UnLoader, to extract data from data files. They have a nice rate they charge for the service as well. There are other groups that have such tool, and they charge the for the service as well.

Pdftotext extracting from image files mystery

hello all, just had a bit of a shock when I ran pdftotext (accidentally) on an unocr'd pdf file, and it extracted all the text. Running pdftohtml (as I'd intended) produced the expected output - i.e. png dumps. Curious, I then tried running it on a bunch of other downloaded files, and with the exception of one, pdftotext extracted the text from ALL of them. The mystery then is that it isnt using any ocr (no tesseract dependency, plus it's way too quick), so clearly it must be pulling it directly from the files. But if the text really is there in the original, then presumably the people who scanned them didn't know, else they'd have left it there. The only thing I can think is that some common piece of pdf software (probably acrobat) has ocr built in, so it's scanning them automatically and then encoding the hidden text in the pdf.
take for example (legal):
http://www.cd3wd.com/cd3wd_40/JF/JF_VE/SMALL/27-714.pdf
open up in a normal pdfreader - very clearly a (poorly) scanned document. Now run 'pdftotext -layout' on it and you get a pretty impressive text file, considering the source. Sure, some of the formatting is messed up, but I'm sure anyone with sed knowledge could quickly sort most of that out. Besides, that's one of the worst documents - on most others it was perfect, maintaining columns (even tesseract can't do that) and everything.
It makes for a fantastic command line pdf reader that works on almost all the files I've thrown at it, and since pdf's are almost the only reason I ever have to load up X, consider me tickled pink.
Just thought I'd mention it here, as a google search brings up nothing on the issue. hope someone finds it useful

Yes, Adobe Acrobat has a feature that allows you OCR the text and insert the text as a separate layer behind the image. Such PDFs are called "Searchable image PDFs". There are no doubt some other commercial software options that can do this too. The copier/scanner/multifunction device in my office actually does this automatically when you scan in a text PDF.
Theoretically, it is even possible to create PDFs like this using free software on linux (a combination of ExactImage and Cuneiform; or WatchOCR).
See, e.g., this blog post:
Searchable PDFs with linux
and this slashdot story:
Open Source OCR that makes Searchable PDFs
My own experiments with trying to get something like this to work have not been very successful--at least the quality of the result is nowhere near what I'm getting with our work printer.
If you like pdftohtml, you should also know about pdfreflow, which takes the XML output of pdftohtml with the -xml flag and creates an html file that can be reflowed (I.e., is smart about paragraph breaks, removes page numbers and recombines words broken through hyphenation and so on).

IMAQ image to array vi not working with images extracted from avi file

Hi,
I downloaded some avi's and uncompressed them so that I can analyze them within labview. I am trying to convert images I am reading from the avi file to an array. When I use "IMAQ image to array" I get the following error " IMAQ Image To Array Invalid image type" -1074396080.
I am able to display each read image and save them to the hard drive, but I am unable to convert the vision image to array. I verified that the image extracted from avi is the same as the image type I created in memory to hold the image.
Please see the attached vi I created.
thank you

Hi all, this thread was useful for me...but i have another doubt... when I try to extract a single plane (Luminance, Saturation, R,G,B...anyone) and try to save it in jpg as gray image, it saves an image with blue tones. I have examinated it using Matlab and checked that Red plane has low values (but not zero), the same for G plane and high values for B plane. An image of the VI is attached.
Thanks in advance

Extracting from flat file for testing inplace of ECC(r/3)

Hi Expert,
Please help me out and give me your suggestion.
We are creating a custom table in ECC it is under progress.
I would like to create infoObject, transformation, DTP and Cube and create queries with loading info by flate file. Later on connection whole provider to table.
Give me suggestion is ther any problem for this Or any good opinion.
Thanks in Advance

Loading from a flat file for testing has worked well for me. We recently wanted to test an ODS object, but I didn't want to create a custom extracter until we knew if the ODS object would work for us. So under my infoSource I created a quick infopackage that pulled some test data from a flat file. We've loaded test data into cubes before. Only problem that I ever had was when I used Excel to create the flat file. Excel wants to truncate leading zeros. 0calmonth for example needs to be loaded as 072007 not 72007.

How to ban extracting from .jar file?

Hello
Problem of .jar file is: .class files can be extracted (with winrar ...) and decompiled. I don't want my classes to be decompiled. But I still need my jar executable of course.
Is some solution which bans extraction without any impact on executability?
Thank you very much.
Tony

Is some solution which bans extraction without any
impact on executability?Hmmmm you could not put any class files in your jar. That would eliminate the extraction problem. Probably would be detrimental to execution.
What do you think happens when your app runs? It just magically knows about your classes without extracting them?
Not so much no.
Use an obfuscator.
Or if that's not good enough use another language or just panic.

Extracting from EAR file

Hello Experts,
Right now we are on EP6 upgraded to EP7
I have a modified sap.comessus.ear file from EP6.
But, we lost the source code on the track and track itself during upgrade to NWDI.
Is there anyway to get the source code from this EAR file. Or any way we can deploy this ear file on different J2ee engine. So, we can run it on our new portal.
your help is greatly appreciated.
Thanks,
James

Hi James,
the developer chose to keep or not the source class into .ear file.
So you can unzip the .ear file (using WinRar), in this way you will be able to see the folder structure and various files, you will see a lot of .class file that are binary class and if you are lucky you can find a lot of .java files. Open the .java files with a txt editor like notepad, this is the source code.
Hope this help you.
Regars,

Not able to extract performance data from .ETL file using xperf commands. getting error "Events were lost in this trace. Data may be unreliable ..."

Not able to extract performance data from .ETL file using xperf commands.
Xperf Commands:

How to extract data from .xltm file in a (dataset, datatable or a list) using wpf c#

Hi all,
As we can get data from .xls, .xlsx file in a dataset. Now i want to read all the entire data from .xltm file.
I also want to get all sheets name from .xltm file. I am using .Net framework 4.5, Visual studio 2012.
Please help me. I am unable to extract it. It is urgent.

Hello Kalpna Bindal,
I just investigate this issue and use the following way but it does work:
private void Button_Click(object sender, RoutedEventArgs e)
// initialize connection
OleDbConnection con = new OleDbConnection();
con.ConnectionString =
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\Fruits1.xltm;Extended Properties=\"Excel 12.0 Xml;HDR=YES;\"";
//pass query to Insert values into Excel
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "insert into [Sheet1$] values('')";
cmd.Connection = con;
// EXECUTE QUERY
con.Open();
cmd.ExecuteNonQuery();
con.Close();
I then did a research about this issue and find the following case:
http://stackoverflow.com/questions/22225017/reading-excel-xltm-files-programmatically
To test whether it is possible I use the following code in WPF:
Microsoft.Office.Interop.Excel.Application xltmApp = new Microsoft.Office.Interop.Excel.Application();
xltmApp.Visible = false;
xltmApp.ScreenUpdating = false;
Workbook xltmBook = xltmApp.Workbooks.Open(@"D:\Fruits1.xltm");
Worksheet xlworksheet = xltmBook.Worksheets.get_Item(1);
for (int i = 1; i <= 1; i++)
for(int j=1;j<=1;j++)
string str = (string)(xlworksheet.UsedRange.Cells[i, j] as Microsoft.Office.Interop.Excel.Range).Value;
MessageBox.Show(str);
The result is that I can read this .xltm file and read the firstline without problem.
I would think you can also use this way to work with your .xltm file and output it to your application.
For more details about how to fill to your WPF, common wpf and excel thread will be helpful:

Use LINQ to extract the data from a file...

Hi,
I have created a Subprocedure CreateEventList
which populates an EventsComboBox
with a current day's events (if any).
I need to store the events in a generic List communityEvents
which is a collection of
communityEvent
objects. This List needs to be created and assigned to the instance variable
communityEvents.
This method should call helper method ExtractData
which will use LINQ to extract the data from my file.
The specified day is the date selected on the calendar control. This method will be called from the CreateEventList.
This method should clear all data from List communityEvents.
A LINQ
query that creates CommunityEvent
objects should select the events scheduled for selected
day from the file. The selected events should be added to List
communityEvents.
See code below.
Thanks,
public class CommunityEvent
private int day;
public int Day
get
return day;
set
day = value;
private string time;
public string Time
get
return time;
set
time = value;
private decimal price;
public decimal Price
get
return price;
set
price = value;
private string name;
public string Name
get
return name;
set
name = value;
private string description;
public string Description
get
return description;
set
description = value;
private void eventComboBox_SelectedIndexChanged(object sender, EventArgs e)
if (eventComboBox.SelectedIndex == 0)
descriptionTextBox.Text = "2.30PM. Price 12.50. Take part in creating various types of Arts & Crafts at this fair.";
if (eventComboBox.SelectedIndex == 1)
descriptionTextBox.Text = "4.30PM. Price 00.00. Take part in cleaning the local Park.";
if (eventComboBox.SelectedIndex == 2)
descriptionTextBox.Text = "1.30PM. Price 10.00. Take part in selling goods.";
if (eventComboBox.SelectedIndex == 3)
descriptionTextBox.Text = "12.30PM. Price 10.00. Take part in a game of rounders in the local Park.";
if (eventComboBox.SelectedIndex == 4)
descriptionTextBox.Text = "11.30PM. Price 15.00. Take part in an Egg & Spoon Race in the local Park";
if (eventComboBox.SelectedIndex == 5)
descriptionTextBox.Text = "No Events today.";

Any help here would be great.
Look, you have to make the file a XML file type -- Somefilename.xml.
http://www.xmlfiles.com/xml/xml_intro.asp
You can use NotePad XML to make the XML and save the text file.
http://support.microsoft.com/kb/296560
Or you can just use Notepad (standard), if you know the basics of how to create XML, which is just text data that can created and saved in a text file, which, represents data.
http://www.codeproject.com/Tips/522456/Reading-XML-using-LINQ
You can do a (select new CommunityEvent) just like the example is doing a
select new FileToWatch and load the XML data into the CommunityEvent properties.
So you need to learn how to make a manual XML textfile with XML data in it, and you need to learn how to use LINQ to read the XML. Linq is not going to work against some flat text file you created. There are plenty of examples out on Bing and Google
on how to use Linq-2-XML.
http://en.wikipedia.org/wiki/Language_Integrated_Query
<copied>
LINQ extends the language by the addition of query
expressions, which are akin to
SQL statements, and can be used to conveniently extract and process data from
arrays, enumerable
classes, XML documents,
relational databases, and third-party data sources. Other uses, which utilize query expressions as a general framework for readably composing arbitrary computations, include the construction of event handlers[2]
or
monadic parsers.[3]

Hi,
We have exactly the same error in IBolt. This error happens sometime and we don't find the reason.
IBolt has been upgraded to Version 3.1 SP1 and a fix has been developed by the support. After installation, we've work hardly during 2 days for testing all the flows by the customer without having this error.
Ibolt works as a service and when this error occurs, the service stopped and must be restarted.
In our flows, we have put a delete of the observer.dll file just before the rest of the flow but it doesn't solve the problem.
Deleting the directory can be temporarly a solution but the error come back another day.
Each time the SBO client or DTW is started, the %temp%\SMS_OBJ_DLL directory is created...
When you just delete the observer.dll file and leave the rest of the directory like it is, the file is re-created when you start and log to SBO. I would say that this file is a copy of another file observer_800178.dll (800178 depending of the version of SBO yoi have). 800178 corresponds to SBO 2007 A PL 42.
Do you have more information since your post has been send ?
Thanks in advance for your help.
Best regards.

Extracting a flat file from oracle table

I have moved the knowledge module KIM ISO SQL to FileAppend from the Metadata to my project folder.
But when I create an interface mapping the oracle table and a flat file on a different unix server, in the drop down menu , it shows only KIM SQL TO SQL and KIM Control Append.It does not show up the SQL to FileAppend knowledge module option.
What should I do to extract a flat file from oracle table?
Thanks

All IKM in the Drop Down Menu are dependent of the target technology.
A question, at this interface, is your target table a file ?

Extract All Embedded Files in All Folders and Save Each? Copy/Paste from PDF to Word?

I have most of what I need here, but I’m missing 2 important pieces.
#1) I want to copy/paste from all PDF files in a folder and paste the copied data into a single Word file.
It works fine if I have ONLY Word docs in my folder. When I have PDF files and Word files, the contents of the Word files are copied in fine, but the contents of the PDF files seem to come in as Chinese, and there is no Chinese in
the PDF, so I have no idea where that’s coming from.
#2) I want to extract all embedded files (in all my Word files) and save the extracted/opened file into the folder. Some embedded files are PDFs and some are Excel files.
Here the code that I’m working with now.
Sub Foo()
Dim i As Long
Dim MyName As String, MyPath As String
Application.ScreenUpdating = False
Documents.Add
MyPath = "C:\Users\001\Desktop\Test\" ' <= change this as necessary
MyName = Dir$(MyPath & "*.*") ' not *.* if you just want doc files
On Error Resume Next
Do While MyName <> ""
If InStr(MyName, "~") = 0 Then
Selection.InsertFile _
FileName:="""" & MyPath & MyName & """", _
ConfirmConversions:=False, Link:=False, _
Attachment:=False
Dim Myshape As InlineShape
Dim IndexCount As Integer
IndexCount = 1
For Each Myshape In ActiveDocument.InlineShapes
If Myshape.AlternativeText = PDFname Then
ActiveDocument.InlineShapes(IndexCount).OLEFormat.Activate
End If
IndexCount = IndexCount + 1
Next
Selection.InsertBreak Type:=wdPageBreak
End If
On Error Resume Next
Debug.Print MyName
MyName = Dir ' gets the next doc file in the directory
Loop
End Sub
If this has to be done using 2 Macros, that’s fine.
If I can do it in 1, that’s great too.
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Hi ryguy72,
>>When I have PDF files and Word files, the contents of the Word files are copied in fine, but the contents of the PDF files seem to come in as Chinese, and there is no Chinese in the PDF, so I have no idea where that’s coming from.<<
Based on the code, you were insert the file via the code Selection.InsertFile. I am trying to reproduce this issue however failed. I suggest that you insert the PDF file manually to see whether this issue relative to the specific file. You can insert PDF
file via Insert->Text->Object->Text from file.
If this issue also could reproduced manually, I would suggest that you reopen a new thread in forum to narrow down whether this issue relative to the specific PDF file or Word application.
>> I want to extract all embedded files (in all my Word files) and save the extracted/opened file into the folder. Some embedded files are PDFs and some are Excel files.<<
We can save the embedded spreadsheet via Excel object model. Here is an example that check the whether the inlineshape is an embedded workbook and save it to the disk for you reference:
If Application.ActiveDocument.InlineShapes(1).OLEFormat.ClassType = "Excel.Sheet.12" Then
Application.ActiveDocument.InlineShapes(1).OLEFormat.DoVerb xlPrimary
Application.ActiveDocument.InlineShapes(1).OLEFormat.Object.SaveAs "C:\workbook1.xlsx"
Application.ActiveDocument.InlineShapes(1).OLEFormat.Object.Close
End If
And since the Word object model doesn't provide API to save the embedded PDF, I would suggest that you get more effective response from PDF support forum to see whether it supports automation. If yes, we can export the PDF as embedded spreadsheet like code
absolve.
Hope it is helpful.
