Use LV to read data from a file that is already open in another program.

My operators use an office application where they pull up PDF and Word data sheets for various components that we test.
The URL looks like this:
http://team/Service/Motor%20Data%20Sheets/Forms/AllItems.aspx
I have no idea how to get to this from LV.
What I need: when an operator selects a document (PDF or Word) from this list I want LV to know what document was selected and have LV read the data from it.

I mistyped. It's not an office application but a Windows application that stores documents on our company intranet. The user clicks on a hyperlink of a document that can be either in Word or PDF format and it opens the document. I want LV to "see" this somehow so I can get the text data from the document. I realize this is more Microsoft/.net/magic than LV but was just wondering if anyone else has done something like this.

How to read data from a file that is already open by another program

Hey..
I have made IV, where I'm trying to read data from a log file, that is being updated by another program while my IV runs.
To be clear, this program writes data continuously to this file and I want to read from the file in LV at the same time.
The problem is that LV reports an error when I'm trying to read the log file, even if I use to "read only" mode.
I believe that the program that is producing the file, have some kind of lock on the file. I have tryed to copy the file and then reading from the copied file, but LV throws already an error when I try to copy the file.
Has anyone tryed this, and found a solution.?
Additional info: The program that produces the file is STM Studio
Best Regards
Allan

Hi Alha,
when that file is locked by the other program you can't do anything about that - apart from quitting that other program. Probably this isn't an option to you…

Read a file in labview already open in another program

Hi,
I am using labview to read a text file, also there is one more software(not lab view) is writing to the same file which I am using to read.My problem is that ,is it possible to read a file which is already openned by another software ?
Thanks,
Sachin Kudari

Hi Sachin,
that depends on that other software...
- When writing to a file usually it is opened with exclusive access rights to the writing software. No other software can open the file simultanously.
- The file may be opened with non-exclusive access by the writing software. Then LabVIEW may access the file too.
- The file may be opened with exclusive access rights by the writing software for each write access and released when write access is finished. Then LabVIEW may open the file in parallel, but errors may occure for simultanous file access from both parties...
It's never a good idea to share one resource (your file) for several requests (your different executables). It may work (with several conditions), but it doesn't need to.

Need Help With Exporting EPS Files That Will Be Opened In Another Program

I am trying to export some files from Illustrator in EPS format, to be used in another program called "Blufftitler". Their documentation is pretty sparse and doesn't go into much detail. It only mentions the following:
"Limited support
BluffTitler has limited EPS support. It only imports filled shapes built out of lines and curves from uncompressed, unoptimized EPS files."
No matter what settings I try in Illustrator when exporting the EPS file, it won't open in Blufftitler, and keeps throwing me errors. I tried Choosing "Illustrator 3" as the format, and turning off the preview option. I also tried "expanding" the shape itself several times too. Is there some other way in Illustrator to just export a bare-bones EPS files without any extras or other stuff that might cause problems with other programs?
The funny thing is, when I create EPS files with another program, such as Vector Magic, they work fine in Blufftitler - it just seems to have a problem with EPS files created in Illustrator specifically.
Any help would be greatly appreciated, thanks in advance!

The main problem is with BluffTitler is it doesn't have a very good eps handler as it can really only import eps files that are about 10k each and are not overly complex. If you look at all the sample .eps files that come with it, each one is about 1 or 2k each. A simple circle in Illustrator, even when saved as v3 without a preview, is around 258k. The reason for the larger file sizes is due to the extra things being saved in the file that aren't even on the page, such as brush presets and graphic styles. The sample .eps files that come with BluffTitler don't have these presets so the files are already smaller.
Something you may want to try is to open up one of the sample eps files and use that file for your vector work but save the file with a new name. I found that by doing this I could get the files down to a much smaller size. You may also want to setup any vectors in Illustrator first, save them, and then open the files in InkScape, http://www.inkscape.org. From what I've read, InkScape can get you fairly small file sizes so it's something you should check out.

I have to check the file :-
Validation are 1st line should start from 0 else it should raise an error and insert that error into one table .
The for 2nd line also same thing ..it should start from 9 else it should raise an error and insert that error into one table .
Then the 3rd line should start from 1 else it should raise an error and insert that error into one table .
After that i have to do a validation like i will read the 1st line 2nd column .. It should be like this BP-V1 else raise an error and insert that error to a table . Then i will check the 3rd column which is 20100928 , it should be YYYYMMDD format else same thing ERROR.
Then like this for all columns i have different validation .......
Then it will check for the 2nd line 3rd column . this is an account no .1st i will check it should be 12 char else ERROR .Then I will check that what user has imputed in the form.Like for example User putted 111111111 then i will check with this 000111111111 which is there in the 2nd line . I have to add 000 before that Account no which user imputed .
Then the lines which is starting from 1 , i have to take all the 2nd column for all the lines which is starting from 1 and i have to do a sum . After that i have to compare that sum with the value in the 1st lines ( Starting from 0) 6th column . It should be same else ERROR ...
Then same way i have to count all the lines which is starting from 1 . Then i have to compare with the 7th column of 1st line . It should be same . Here in this file it should be 9.

How to read data from a file in OSB

hi guys,
Recently, I've got a problem with reading file from specific location. I've actually followed this post OSB 11g - Read or Poll File in OSB - Oracle Fusion Middleware Blog, and then
I know how to read a file. However, it does not as expected. Because, I've found no way to read data from the file. Therefore, no chance to manipulate the data like assigning to a variable, or extracting ....
Hence, is there any way to read data from file by using proxy service in OSB ??? No Java code ???
by the way, supposed that there is no way to read data from a file in OSB. So, What purposes will the way in the post above be used for?
Many thanks in advance

Here is an example - XML file contains Book Title and Author. I would like to read Book Title and Author from XML file and set it into ViewObject Attribute and then display Book title and Author in ADF UI page. Also when user modifies Book title and Author, I would like to store it back in View Object.
Please help me with this requirement and let me know if any solution exist in ADF, for populating the ADF UI screen fields with external XML file data.

Read data from Excel file and diaplay in Webdynpro

Hi all,
I need some help. I have a Excel file with set of name, phonenumbers . I want to know how to display the data using Webdynpro. Could some one help me. help is appreciated and I promise to award points for right answer.
Thank you

Hi
i can explain you to read data from Excel file
First You have to download the jxl.jar file. You can get this file from the Below site
<a href="http://www.andykhan.com/jexcelapi/download.html">jexcelapi jar</a>
It will be in Compressed Fromat So Unzip it to get the Contents
After Unzipping The File You will get a Folder (jexcelapi/jxl.jar)
Now in NWDS open web dynpro explorer, Right Click Your Project, a popup menu will appear and in that click Properties
You will get window displaying your Project Properties
On Left Side of the window You Will Find "Java Build Path"
Click That "Java Build Path" and you will get 4 Tabs Showing ( Source,Projects,Libraries,Order and Export)
Click Libraries Tab
You will find options many options buttons
In that click the Button "Add External Jars"
You will get Window in order to fecth the jxl.jar file from the location you had stored
After selecting the jxl.jar i will get displayed and click ok
Now Open Navigator
Open Your Project
You will find Lib folder
Copy the jxl.jar to that lib folder
Note : You cannot Read the Content from the excel file directly
First You Have to copy that file to the Server,
And from the Server you can get the file absolute path
With the absolute path you can read the contents of the Excel file
You have to save the Excel file as .xls Format and Not as xlsx format i will not accept that...
You have Upload the Excel file from the Server Using the File Upload UI Element
This Coding will extract 3 columns from the Xls File

Failed to read data from report file Reason: The table could not be found.

Failed to read data from report file Reason: The table could not be found.
Any ideas to get around this would really help out.

Connection used Views, ODBC System DSN is setup properly.
Approach for import from business view manager and import wizard. both methods failed to import the Business View and underlying reports.
I figure I may have imported the Business View wrong? From Business View Manager I exported from my dev server then imported to prod server.
Apparently I learned exporting my business view also includes the Data Connections that the Business Views are dependent upon.
So which ever folder you specify it copies it there. Originally the all Data Connections Resides on the root folder. To return it to the original location. I deleted what I had exported. Exported this time to the root folder, then only deleted the business views, foundation, elements. Then exported again to the folder where I intended then only deleted the Data Connection.
Makes any sense? So I then had to re point the business views and all the dependent objects to the data connection that resides in the root folder.
I tested the connection, it works fine. I properly updated my crystal reports to the business view in production. Did a sample extract it works as expected.
However when i try to publish, either from Crystal or Publish wizard i get the same error?
As a work around i am thinking, after updating the business view in the crystal reports, shall i re map the fields?? or reexport the business views again?
Any help will be surely appreciated.

Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
 IMPORTING e_content = xmldata ).
 Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
 SOURCE XML xmldata
 RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
 CALL TRANSFORMATION id
 SOURCE shiv = t_internal_tab
 RESULT XML xml.
 CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
 
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!

Use LV to read data from a file that is already open in another program.
