Hi,
I wasn't able to see the diagram of your VI. What I suggest you do is to simplify the problem and make a VI which does not involve the OPC Server, for example. Simplify it to a point where the problem can still be reproduced. And then share the VI with us. We'll be in a better position to hel you then.

Is it APEX bug - "junk data" from flashlight to .xls file
Hi.
Anybody knows how to avoid saving "flashlight icon" column with "junk data" to spreadsheet on user's desktop?
We have APEX application. The summary report's last column is "flashlight icon" which leads to the detailed report. If user clicks on "Save to Spreadsheet Desktop" on the summary report screen, summary report will be saved to spreadsheet on his/her desktop. When the user opens the spreadsheet, the data of the last column seems rowid, such as AADnYlAAZAAAGsaAAd. For user, it seems junk.

If you are working with an interactive report set the column condition to "Request is not contained within expression 1" and set expression 1 to "CSV:HTMLD:XLS:PDF:RTF"

Download data from db to CSV file and need to handle chinese character
Hi , all , I need to write to alow to export data from db to csv file, now the problem is some column is chinese character, in both db and web page it can dispaly the chinese, but in Csv I can't display chinese character, what should I do?

I already have res.setCharacterEncoding("UTF-8"); in my servlet, and db

Are you sure that you have set it on the response? You do not need to set it on the request. Have you read the article? Do you understand the world of characters? It look like you still don't understand it.
by the way, since csv is text file , how can I bold my University number??? in sb = new StringBuffer();
sb.append("University Number");Not possible with CSV since it is text/plain. Use real XLS if you want to add formatting to cells. -
Extract data from Oracle in excel file
Hi,
I have a requirement where in I need to extract data from Oracle in excel file and the excel worksheet name should be "Data".
for eg. excel file name "AR Data_DDMMYY" and excel worksheet name "Data"
I have used the UTL_FILE API to extract the tab delimited data which can be opened in excel but it is not exactly an excel file as the worksheet name is same as the file name.
I tried using utl_file.fcopy and frename.
Is there any way to do this using PLSQL?

Hi,
I was able to generate the excel 2007 file with the data using the package from below link;
http://technology.amis.nl/2011/02/19/create-an-excel-file-with-plsql/
but the requirement is to generate excel 2003 file.
I tried changing the .xlsx to .xls and it gives a note while opening the file "The file you are trying to open, abc.xls, is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"Then you have three options:
1) stop using anton's package and find another one that supports the old and deprecated version of Excel 2003
2) write your own package to produce an Excel file.
3) Upgrade your version of Excel to a recent version
I tried the programs from other links on the forum but I am still getting this message. The client does not want this message to be displayed as the excel file works as an input to another system.
Can anyone help me with the issue?
Also, is it true that the programatically generated excel file is actually an xml file which is renamed to .xls and hence it shows the message while opening such files?Yes, Excel supports several different formats for it's files. By default, if you save an XLS files from Excel, it writes it out in a Microsoft proprietary binary format, which you would be hard pushed to replicate easily from PL/SQL. Excel also has the ability to save it's files as XML format, which is more readable and easier to produce programatically, whilst still allowing you to have multiple sheets, formulas and formatting included in it. That's the format that most people who need formatting and multiple sheets opt for when programatically generating their data as excel workbooks. (There's also an SLYK format that people used to use before that, but it's not as flexible)
If you want to write your own, the easiest thing to do is to start with a blank workbook in Excel, and put in your basic requirements e.g. a couple of named sheets, and some data in different formats (number, date, text etc.) and different formatting options etc. Save that file in XML format from Excel and then open up the file using notepad/wordpad to look at the structure. There'll be a whole load of redundant rubbish Microsoft put in there, but you should be able to figure out the basic structure of XML required to give you what you want. -

Static lookup lists:read data from a Java *.properties file
Hi
i need to make static lookup lists i am using read data from a Java *.properties file

String temp=Locale.getDefault().getLanguage();
String propertyFile =

For English(TEST_en.properties) it is good and working
For Arabic(TEST_ar.properties) read from correct file _ar.properties

How to upload the data from excel(3 tabs) file to sap environment
Hi all,
This is Mahesh.
how to upload the data from excel(3 tabs) file to sap environment (internal tables) while doing bdc.Hi,
The FM 'ALSM_EXCEL_TO_INTERNAL_TABLE' makes it possible to load a worksheet into an internal table in ABAP.
However, if you want to get the data from several worksheets, I think you are stuck with OLE access to your Excel Workbook...
You can find a solution for 2 worksheets in this post :
TO UPLOAD DATA FROM 2 EXCEL SHEETS INTO TWO INTERNAL TABLES
I think you can easily modify it to handle any number of worksheets.
Hope it helps !

Which CKM is used for moving data from Oracle to delimited file ?
Hi All
Please let me know Which CKM is used for moving data from Oracle to delimited file ?
Also is there need of defining each columns before hand in target datastore. Cant ODI take it from the oracle table itself ?Addy,
A CKM is a Check KM which is used to validate data and log errors. It is not going to assist you in data movement. You will need an LKM SQL to File append as answered in another thread.
Assuming that you have a one to one mapping, to make things simpler you can duplicate the Oracle based model and create a file based model. This will take all the column definitions from the Oracle based model.
Alternatively, you can also use an ODI tool odiSQLUnload to dump the data to a file

Acquire data from a tab delimited file using a popup dialog object on a stamp
I am trying to import data from a tab delimited file using a popup dialog object on a stamp. I have purchased the book by Thom Parker--All About PDF Stamps in Acrobat and Paperless Workflows and have been working through the examples in the appendix.
My problem is understanding how to bring the data into the dialog object from the file.
I don't want to plagiarize his book--so am electing at this time not to show my code. The script is reading the file, just not bringing in the records from the file so that I can select which line to import into the stamp.
I have typed in the code exactly how the book describes, but when the popup dialog object is selected, there is nothing in the drop-down. When I click OK, the first record is put on the stamp--except for the fields that I am wanting to appear in the dialog object popup box.
I have searched the forums, and also the JavaScript reference. There are examples of the popup dialog object, but none of them show how to import the data from a file--just for the items to be typed in as the list.
Any help would be greatly appreciated! i have been trying to work on this for several months now.Karl
Thank you for getting back with me!
In answer to your questions:
1. Your trusted function is not a trusted function. Did you put this
function into a folder level script so that it will get executed at system
startup?--
yes--I saved the script as a .js file and put it in the following path (I have Acrobat XI Pro for Windows)
C:\Documents and Settings\tjohnson\Application Data\Adobe\Acrobat\Privileged\11.0\JavaScripts\GetTabData.js
2. The script cannot find your tab delimited data file, or it cannot
extract the data. Did you add the data file in the correct location? The
location from the script in the book would be c:\mydata\Contacts.txt
Yes--the file is in the same path as the book.
Below is my code that references the file.
var cPath = "/c/mydata/Contacts.txt";
the slashes in the book go in the direction of the text above--should they go in the direction that you have in your question?
Also, the name and email address need to be separated by one Tab character.
They are.
3. The fields need to be named the same way as the columns in the data file (the two names are in the first line of the file).
My headings are RevByFromTab and EmailFromTab--which match the names of the two fields on the stamp.
So, check that you are not getting any errors in the JavaScript console
(Ctrl-J or Cmd-J), and verify that the tab delimited file is in the correct
location
When I run in the java script console--and I just run the script on the stamp,
it says
TypeError: event.source is null
17:Console:Exec
undefined
When I place the stamp on the page, the popup box is working, but when you click on the down arrow, there is nothing listed. When I click OK, the RevByFromTab is populated by the first item in the file, but the EmailFromTab field says undefined.
Thank you

How to import data from excel or csv files to Oracle table
hello everybody,
I am new here and new in Oracle. I would like to know the steps how to import data from excel or csv files to Oracle table.
Let say I already have table inside the Oracle. Then my user give me the sets of data inside the Excel Worksheet.
So, how can I import the excel data into Oracle table.
Thank you in advance.
cheers,
shimaEven easier. Download JDeveloper 11G from this site.
Set up the database connection, right click on the table, select Import->Excel and specify your file to load it. On the import pop-up, you must view and update each tab indicating Columns, Data Types, and DML.
Columns -- move the selected columns that you want to load to the box on the right
Data Types -- select column name from second column to which the data for each column of the import file should load
DML -- click this tab to generate the INSERT SQL
Once done click 'Insert' -

Writing data from array to file
May i know how to write string from a array into a file.
I have use string tokenizer to extract every line from a file using readline and use stringtokenizer to spilt the line using tab delimiter for processing.
But if i want to write data from array to file with tab as a delimiter and how to go to the next line. How do i do that. Below is the task and i have state a simple example on a array i have and the file output that i want.
Pls advice.. Thanks
eg of a array
array[0] = Data
array[1] = One
array[2] = Data
array[3] = Two
array[4] = Final
array[5] = Data
From the above array, i want to write to a file so that it will appear something as below
Eg textfile.txt
Data One
Data Two
Final Data
PLs attached a simple code as a example as i am only begining to start useing the IO feature in java. ThanksReally thanks for your help,
but u are mentioning that i have already know the number of countters in advance , that is to say the 2 * counters.
But is there a way to solve this problem which i mean if i dun know the number of predefined counters. Maybe i should say, there is more than 2 counters and in another situation, the counters will only be defined during runtime. Actually the solution u give will work nicely with 2 counters. but wat if the counter is more than 4, i wll have to concatenate the string a lot of time. so is there any solution around this problem. That why i am wandering if tere is any solution to write to the file when the counters can be only determined in runtime
Pls advice on the above with a code samples if possible.
