Check if files exist using ABAP

Hi All,
I'm currently using FM: FILE_GET_NAME_USING_PATH, and I'd like to do a check to see if the filepath with file (i.e. /com/tmp/file.txt) I am getting back exists or not.
Very simple question, just not sure what to do.
Thanks,
John

There is a class that provides methods to check, if a file exist or if a certain directory does exist
CALL METHOD cl_gui_frontend_services=>directory_exist
    EXPORTING
      directory            = lv_path
    RECEIVING
      result               = lv_valid
    EXCEPTIONS
      cntl_error           = 1
      error_no_gui         = 2
      wrong_parameter      = 3
      not_supported_by_gui = 4
      OTHERS               = 5.
      CALL METHOD cl_gui_frontend_services=>file_exist
        EXPORTING
          file                 = x_file_with_path
        RECEIVING
          result               = y_file_exists
        EXCEPTIONS
          cntl_error           = 1
          error_no_gui         = 2
          wrong_parameter      = 3
          not_supported_by_gui = 4
          OTHERS               = 5.
Hope that helps,
Michael

In ecatt - how to check at database level using ABAP

Hi,
How to check at database level using ABAP in Ecatt tool.
say,for example I want to check a particular sales order is invoiced or not ,at the database level and if it is invoiced I have stop proceeding to invoicing of that sales order number.
Could anybody suggest on this with an example?
thanks.

Hi,
you can use the command GETTAB to access single db records.
Full specified or partitial specified keys can be use at GETTAB. It will return always only one record, also if a couple could match your selection.
For more advanced scenarios you can also use eCATTs Inline ABAP. In a block between the commands ABAP. ENDABAP. you can code ABAP statements, e.g. SELECT ... INTO TABLE ...
eCATT script parameters of type 'V' defined in that script using ABAP/ENDABAP will be transfered into the ABAP block and back to script after ABAP perform.
Best regards
Jens

Checking file exist using file exist operator

Hi all,
My environment is owb 9i. DB is oracle 9.2.0.8
My business requirement is,
If file exists in the landing directory the next instant my mapping should start execution other wise it should wait untill the file arrives there.
How could i achive this functionality???
For this i am utilizing the file exist operator in process flow.
When the file exists in the specified directory i am able to execute the process flow quite fine but when the file doesnt exist in the specified directory the file exist operator is in wait state and even after when the file is placed into the directory, still the process flow remains in the wait state.
please suggest me a way.
thanks in advance.
ram.

Hi Ram,
The problem you are hitting here is that there is no wait activity and no loop activity (yet) in the process flow editor. So it is hard to model this logically.
Would it be a good idea to write shell script that does similar things? You could check for a file, pauze and check again. Then error out or succeed...
In the 10gR2 release of OWB you can completely model this using waits and loops.
Thanks,
Jean-Pierre

Use thread to check for file exists. How?

public class FileSearcher extends Thread
     String name = "Unknown";
     //RunFileSearcher rfs = new RunFileSearcher(name);
     //FileSearcher rfs = new FileSearcher(name);
     File f = new File();
     Thread t = new Thread(); // create the thread
     t.start(); // start the thread running
     public void run(name)
          if( f.exists(name) )
               System.out.println("*** File " + f + " has been created. ***");
          else
               System.out.println("Searching for file " + f) ;
}How do I use each thread to check for each file exists per sec??
Please Help Thanks

1) Why are you using Threads?
2) It is preferrable to implement Runnable.
3) This is all incredibly pointless (see point 1)

Dialog prompt and check if file exists, and use the result of dialog

I have this working script and I want to change the way it behaves.
I want a dialog to come up, Do you want to skip or replace existing files.
Then the result of the dialog to be used in the reast of the script.
I've added it in the script where I need to use it. in noce big letters, hopefully its not a big job.

Problem Checking if File Exists When App is Launched

"The name 'TryGetItemAsync' does not exist in the current context". I am new to C# and phone app development. Any help would be greatly appreciated. Below is my code:

It seems that TryGetItemAsync is a method on a StorageFolder, so you will need to do something like:
myStorageFolder.TryGetItemAsync(LastUser);
See here:

If you go to that link and scroll down to the bottom of the page, it says:

Check if file exists returns false. File is in system32

I'm having a problem detecting if a file exists which was simply copied to the system32 directory. I tried moving the file to various other directories and simply using a vi with the "Check if file or folder exists" action. I've narrowed it down to not being able to find the file if I copy it to either c:\windows or c:\windows\system32.
I thought this could be a permissions issue, but did my best to assign the user name full control of the folders.
Another interesting thing is if I make the file input a control and click on the "folder" icon to open a list of files, I cannot see the newly copied files in system32 directory either. Very strange.
This is on a Dell PC, Windows 7 professional/Labview 2010 SP1 (note I am running the vi. as an executable on this machine). Could it be some setting in my project build?
Solved!
Go to Solution.

If you're using Windows 7 64-bit, it may be related to the problems the user was having here:
http://forums.ni.com/t5/LabVIEW/Problem-Using-quot-msg-quot-command-with-quot-System-Exec-vi/m-p/153...
It may be that the LabVIEW functions are 32-bit and are getting redirected.

Applet checking if file exist and if no copy this file

Halo, everyone,
I'm new to java and I need an applet which is able to check if certain file exist on user's hard drive and if not to copy it.
I read that this is possible in certain circumstances, that applet has to be trustes and so on, but that's not my problem. My request is the applet code that checks of existance of certain file.
I'll lbe very thankful if someone could give me such applet or point me to place where I can see steps to creare it myself.
Thank you in advace onse again.

Thnaks a lot for your answers. I really ppreciate!
How could I make the applet using such permissions i
how than it would work?I don't understand, in your first post you said "I read that this is possible in certain circumstances, that applet has to be trustes and so on, but that's not my problem. ". I assumed from this that someone else was dealing with the security aspects.
A starting point to signing Applets is - http://java.sun.com/developer/technicalArticles/Security/Signed/ but Google willl find you a whole load of information.

Java script in HTMLDB to check if file exists in Unix file system

How do I use javascript to check if file is exists in Unix file system. I would like to dispaly the columns only if file is exists.

Hello,
This is one of those features that the manuals do not cover.
How to use and build AJAX features could be a whole book all by itself, and it's not really HTML DB specific feature even though we have built some hooks in application and javascript to make it easier.
Take a look at this thread
Netflix: Nice UI ideas
and I've built some examples here
http://htmldb.oracle.com/pls/otn/f?p=11933:11
Or just search the forums for AJAX or XMLHTTP

Check if file exists in file receiver adapter

hello,
we have following scenario -> proxy to file
before appending to the file, it should be copied/renamed to a "tmp" file
xi should then append to that tmp file and copy/rename the file back to the normal name
I tried it with "Run operating system command before message processing" but
it's not working
anybody has an example on how to use those settings before/after message processing ?
regards,
michel

Hi Michel,
little confused,
1) before message processing do there any file exists?
2) why should we change file name to 'tmp' and append data to that and again rename that file ?
con't we directly proceed in append mode with file name?
When we use single command say for example cp or mv (copy or move) the commands then
eg: cp %F /var/opt/data/outbound/Test/Dummy.txt
when we club commands together or try to redirect the outputs of commands
eg: cp %F /var/opt/data/outbound/Test/Dummy.txt & mv %F /var/opt/data/outbound/Test/Dummy.txt
        or
      cp %F /var/opt/data/outbound/Test/Dummy.txt
      mv %F /var/opt/data/outbound/Test/Dummy.txt
Include all ur command in one file and call that file in the OS parameter

Opening a pdf file without using ABAP

Hi All,
    Can I open a pdf file in the ITS without using ABAP
    coding. I mean by using Java Script in an another
    dialog/page can i open a pdf file. If anyone has got
    any idea or sample code please let me know.
Thanks,

Hi,
Where exactly you want to open the file?
The most simple way would be to upload the file under MIMES and provide the URL in the corresponding ITS service.

How to Check Images File Exist? in different server

Hi,
I have 10 different coldfusion server.
for example 9 server is for the web application site - for
example
http://myserverone/studentweb
the other one is for images website, just for displaying
student picture - for example
http://myserverimage/studentpicture.
the purpose of this website is to display student picture
that i store as gif files.
from my studentweb website i will call the images from
studentpicture website as source for my image placeholder.
for example this is my code i'm calling form
http://myserverone/studentweb
website:
<img src="
http://myserverimage/studentpicture/#studentnumber#.gif"
alt="" name="studentpicture" width="160" height="200">
my problem is, if there is no specific student picture in my
studentpicture website, then the placeholder will display an X (
mean the images not found )
how do i prevent the X to display?
how do i using coldfusion or any kind of way to check if the
images exist on that website ( different server ), so if the images
is not found, i can display a default images? i can do this if i'm
calling the website in the same server, but not using a different
server.
this is like using other website images for your own personal
website and sometimes the owner delete the images from their
website, and i want to display my own images if that images been
removed from the source website.
anyone have done this before?
thanks for suggestion and guide...

1. Use CFHTTP with method="HEAD".
2. See, if the HTTP status code is 200.
The head-method is of course more efficient, as it doesn't
need to "get" the message body. However, a status code of 200 is
possible even when the requested image file is no longer on the
server.
