Try to check whether a file already exists on disk by using fileExists

Hy all,
i try to check whether a file already exists on disk in my
Action scirpt.
I found this link about fileExists:
link
So i tried somethink like this in my code, but without
success...
if(fl.fileExists("file:///C|/toto.txt"))
{gotoAndPlay(2);}
else
{gotoAndPlay(3);}
Is it not the right syntax?
Thank you for your help.

Did you build and application from the swf with mProjector?
The only
way this and other mProjector functions will get called is to
post
process your swf into and application (exe / app) using
mProjector.

How to check if the file already exists in the client directory

Hi all.
I'm on devsuite 10g. I'm using webutil to download files from DB using webutil function db_to_client.
What I need is to check if the file already exists in the client directory and if yes to display a message to ask the user if he wants to overwrite or no. How can I make this???
Here is the code that I'm using to download the file.
Thanks all for the collaboration.
Fabrizio
declare
file_path varchar2(2000) := null;
BEGIN
/** I ask where saving the file on the client machine **/
file_path:= webutil_file.file_selection_dialog
(directory_name => null,
file_name => :bin_docs.name,
file_filter => '',
title => 'Saving file',
dialog_type => save_file, --save_file
select_file => TRUE);
/** I download the file from DB to client **/
if webutil_file_transfer.DB_To_Client_With_Progress
( file_path ,
'BIN_DOCS',
'DOC' ,
'doc_id = '||:bin_docs.doc_id,
'Downloading file',
' '||:bin_docs.name) then
msg_alert('Download del file avvenuto con successo','I',false);
else
msg_alert('Si è verificato il seguente errore in fase di download '||SQLERRM,'I',false);
end if;
end;

How about something like the below:
Note: I have a yes/no alert to asking if they want to over-write the existing file.
DECLARE
file_path VARCHAR2(2000) := null;
over_write BOOLEAN := TRUE;
BEGIN
/** I ask where saving the file on the client machine **/
file_path:= webutil_file.file_selection_dialog
(directory_name => null,
file_name => :bin_docs.name,
file_filter => '',
title => 'Saving file',
dialog_type => save_file, --save_file
select_file => TRUE);
IF webutil.file_exists(file_path) THEN
/** check a file by the same name exists in the selected directory **/
IF show_alert('Ask_overright') != alert_button1 THEN
/** If we say no then set over_write value to false **/
over_write := FALSE;
END IF;
END IF;
IF over_write THEN
/** I download the file from DB to client **/
IF webutil_file_transfer.DB_To_Client_With_Progress
( file_path ,
'BIN_DOCS',
'DOC' ,
'doc_id = '||:bin_docs.doc_id,
'Downloading file',
' '||:bin_docs.name) then
msg_alert('Download del file avvenuto con successo','I',false);
ELSE
msg_alert('Si è verificato il seguente errore in fase di'
||' download '||SQLERRM,'I',false);
END IF
END IF;
END;

Q

How to check if the file already exists in the application server directory

Hi all. I'm on devsuite 10g.
I transfer file from local machine to application server using webutil function webutil_file_transfer.client_to_as and I want to check if the file I'm transfering already exists on the server directory.
How can I make this?
Thanks all,
Fabrizio

use the text_io package and open the file in read-mode.
like this
declare
xFileType text_io.file_type;
begin
xFileType := text_io.fopen('c:\temp\test.txt','R'); --file on the middle tier
-- file exists;
text_io.fclose(xFileType);
exception
when others then
--file doesn't exist
end;

I am only using the traditional if statement till now.So I don't know what makes you think I am expecting others to do my job.

Please be a bit patient and go through all the replies in the thread, before you go accusing the poster. Yeah, I can understand your position, you have nearly 2900 posts as such, but don't you think, it is somehow unfair when you go accusing someone without reading the replies.?

How to check whether a file exist in the program folder or not?

Hi guys,
how to check whether a file exist in the program folder or not? Let is say i recieve a file name from user then i want to know if the file is there not and act on that base.

Look at the class java.io.File and the .exists() method:

Database Adapter Configuration Wizard "File already exists" error

I'm uding JDeveloper 10.1.3.1 on an XP machine running Java 1.5.0_06 and having trouble editing SOAOrderBooking.bpel as part of the tutorial.
The tutorial calls for me to drag a new Database Adapter onto the diagram, select the "soademo_ssn" database and, on page 3 of the wizard select "Perform an operation on a table" and have only "Select" checked.
When I click "Perform an operation on a table", the 5 tickboxes enable and are checked but the mouse pointer remains as an hourglass. If I press "Next" without doing anything else, the Wizard title changes to "Select Table" but never draws its controls, aside from the "Back" etc buttons along the bottom and the decorative graphic to the left. If I do try unchecking boxes to have only "Select" selected, every check box state change generates the error "File already exists" and the path of the .mwp file whose name I specified earlier. The file does exist, but it didn't before I entered the wizard.
I've tried with three different filenames, and with two different database connections- both of which check out fine when I do "Test connection" in their property pages from the Connection Navigator.
If I delete the file after each check state change, I can stop the errors appearing after I untick each checkbox, but the wizard still hangs on pressing "Next" whether the file is there or not.
Does anyone have any suggestions?

I am facing the same issues.
I want to pick the new files and retain the files after polling.
Any idea on this would help me to solve this issue.
Thanks in advance.

SharePoint Library - If I save file from Excel File Save As - then I always get "File already exists. Do you want to replace it?" - Upload works fine though.

Hi there,
In my SP 2010 document library - When I try to save an Excel file from File > Save As menu to the document library it always prompts me "File already exists. Do you want to replace it?" even though the file does not exist in that document library.
To the same document library - if I upload a file then it accepts it all fine.
Any clues why I cannot save files using File > Save As menu?
Thanks.

Hi,
As I understand, the notification pops up when you save an excel file to SharePoint library, while when directly upload file to library, there is no wrong.
Please confirm if the issue occurs to other machines.
Please open Microsoft Office Upload Center on the issue machine, then click settings, clear cache via checking Delete files from the Office Document Cache when they are closed.
http://office.microsoft.com/en-in/excel-help/office-document-cache-settings-HA010388664.aspx
If the issue occurs to client, I’d recommend you also ask the question in Excel forum:

Pop up saying File already exists when saving an excel file while running exe

I have an excel file which I read and write in my application.
When I run the application in development system, it works fine. However when I run the application as an exe and try to save the excel file, it says that 'The file already exists and Do you want to replace?'.
Why does this question asked for exe?

Write to Excel.vi ‏25 KB

Hi Princess_swa,
The problem may be that when you build an exe, it adds another folder called 'builds' into the filepath.
A good way to fix this is to create a case structure, putting extra strip paths into your filepath if running an exe.
I have attached a screenshot of my code doing exactly this for you to look at. The code creates a 'base path' which is then used to reference all of my file paths in my code - and therefore, they will always have the right number of strip paths when it is run. (Note: in my code I have 2 extra strip paths, due to where I've placed the folder, but one should be sufficient.)
Also there is a 'Check if folder exists' VI which you can again link to a case structure, and change the filename if it already exists. Again, I have provided a screenshot of my code which does this.
Hope this helps,
Lou

"file already exists in the destination" during application build

I am trying to build an executable and have gotten the following error:
The file already exists in the destination.
C:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\Sentech LV 82\Shared Library - Trigger SDK\StTrgApi.dll
WHen I start the build I go to "Build Executable" then click "Build"
The VI for the project I have open is the Startup VI and I do not list any Dynamic VIs or Support FIles.
I am using Labview 8.2
I installed a user library for a USB camera from Sentech wich I am using and it works fine in Labview 8.2
When I try to do the build I get the error shown above. The file it is referencing is there along with the .lvlib file.
I tried removing the file shown in the error message to see what would happen and I continue to get the same error even though the file is not there. I even restarted LV and still got the same error.
I am new to the application builder (v7 ?) and have not been able to find any good tutorials. Does anyone have any ideas on this error or a good place to learn more about app builder.
Thanks
Keith

"file already exists"

Hi there!
Photoshop CS4 gives me a strange error. When trying to save a psd file as a jpg (using "save as"), it doesn't change the extension when selecting jpg from the format drop down menu. This results in a message, saying that the original file already exists, or when I save it to a different location, I get a psd file with jpg algoritm. Anyone any idea?
I'm using XP SP3. Other programs do not have this issue. For instance, when working in Adobe Acrobat, and trying to save a pdf in the rtf format, it correctly changes the file extension, and saves the file as rtf.
Thanks in advance!

The problem must either lie with Photoshop, or a combination of Photoshop on my XP configuration.
Most probably, since I don't get that problem. Maybe try installing the 11.0.1 update (if you haven't yet). If that doesn't work, then try to figure out the extent of the issue. Try PS in a different Windows user account (create a new one), and turn off the unnecessary stuff that runs in the background on your computer. If you're not familiar with msconfig, then see this document for turning of background stuff:
http://go.adobe.com/kb/ts_kb404984_en-us
Let us know if either of these change the situation, and hopefully we can help you out from there.
Also, have you installed any plug-ins for PS? Maybe one of these is interfering with Photoshop's jpeg plug-in somehow. Check out this document:

I am using proc_listpidspath() to check whether a file is open or not by some application.
It works in Leopard but not in Tiger.
Can anyone suggest some function or solution so that i can check whether a file is open or not in Tiger.

Atomically creates a new, empty file named by this abstract pathname if and only if a file with this name does not yet exist. The check for the existence of the file and the creation of the file if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the file.
Returns:
true if the named file does not exist and was successfully created; false if the named file already exists So if it returns true, then the file is created and empty.
Secondly, once i write some thing to file.. how can erase all the data from file ?deleting it will get erase the file and return you to the state you started from.
Iif you don't want to create a new file, don't use the createNewFile() method and use the new FileOutputStream/close approach rather than the createNewFile()/delete() pair as already described in this thread.

Cannot create a file when that file already exists

When i try to use Photoshop filters: Adaptive Wide Angle, Shake Reduction and Liquify. An error pop up saying "Cannot create a file when that file already exists".
Just one detail: The liquify filter doen't pop up the error right away, the error occurs just after i press the "ok" button to accept the changes.
I have already tryed to Reset the preferences, tryed to reinstall the PS, Update the PS, download (and install) the latests drivers to my pc.
My Pc fit in all the requirements, have the openGL version: 3.0
I also have Photoshop CS5 installed, in which the liquify filter works perfectly.
Here i have two Print Screen, how it looks:
The first image is just right before a click the "Adaptive Wide Angle"
The second one is right after i clicked it
If you could help me, i already thank you for wasting you time reading this!

Resetting the Photoshop preferences does not reset the preferences for the plugins.
There should be a Plugins folder. If the folder cannot be created it would cause the error you are seeing.
Can you check the permissions on the ‘Adobe’ folder at: C:\Users\jworthin\AppData\Roaming\Adobe.
Can you manually create a Plugins folder in that location or do you get an error?

How to check whether a file is present in the UNIX directory of app. server

Hi,
        I am creating files in the UNIX directory in the application server using :
                   CONCATENATE '/sapmnt/RD1/interfaces/client670/'
                   p_fname '.CSV' INTO w_filename.
           OPEN DATASET w_filename FOR OUTPUT IN TEXT MODE.
          LOOP AT t_output1.
                  TRANSFER t_output1 TO w_filename.
          ENDLOOP.
         CLOSE DATASET w_filename.
I am unable to check whether a file with the same name exists or not. How to check the duplicate state of the file.

You can use the following fm
RZL_READ_FILE
or
use OPEN DATASET FOR INPUT.

Weird CS4 error when saving eps files on a Mac: "...specified files already exist in the target location"

Hi There,
All 3 workstations in our studio are experiencing weird file behavior when re-saving eps files from Illustrator.
Basically Illustrator creates a new file in addition to the original and adds a "-01.eps" onto the file name. If you re-save your original, Illustrator brings up a dialogue box that states:
Some of the specified files already exist in the target location. The files marked below will be replaced:
filename.eps
filename-01.eps
We've been deleting the "-01.eps" files each time but it's becoming tedious. The behaviour occurs when re-saving an eps file to a server or the desktop.
All machines are new Quad-core MacPros running:
- Leopard 10.5.8
- Illustrator CS4 14.0.0
We've checked for Illustrator updates from within Illustrator but we seem to be running the latest version.
Is anyone else experiencing this behavior?
Any help or pointers in the right direction would be much appreciated.
Cheers
Ben

Thanks for the reply.
The error occurs when we save the document but if we choose save as, "Use Artboards" seems to be unchecked so not sure if this issue is related or not. Will re-save the document using save as then see if the issue persists.
Why do we still use eps?
Basically because we've found it to be much more compatible. Our entire logo library is in eps format (18 years worth) partly because it was previously the only format to use and partly because it allows account managers to send logos to clients, printers, TV stations etc and not involve the studio (saving out an eps version).
Although "Create PDF compatible file" is a good idea, we've encountered costly issues with colours and images - especially if the recipient is using old CS software, non-Adobe software or is using some kind of hardware RIP. We now just go with what we know works.
But I do find saving eps versions of everything to be a bit painful. In fact, I've always found Illustrator in general to be a bit painful when compared with Photoshop or AfterEffects. Illustrator seems like it's been developed by a different company some times!
Cheers, and thanks for the help.
