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.

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 รจ verificato il seguente errore in fase di download '||SQLERRM,'I',false);
end if;
end;
