Checking for an existing filename in a directory
How does iFS know that a filename already existing in a directory? I need to capture the information when someone tries to copy a file to a directory before the file is stored in iFS. For example, if I copy a filename to a directory that already has the same filename using windows explorer, the window will pop up a confirm message before the file is written. How do I get the same information? I need to work on the existing file in the directory before allowing it to be overwritten. Any suggestion.
Thanks,
Sun
Just a small improvement on the API call used to check for the existence of an object at a specified path: the Folder method checkExistenceOfPublicObjectByPath() is better than findPublicObjectByPath(), as the former will return true if there is an object occupying that namespace even if the user doesn't have permission to discover that object; findPublicObjectByPath() will return null in this situation.

I'm a DBA working with 3 application developers, they want to know how to check for index existing for certain column
in a table in their schema,
one friend told me , to check for index existing for certain column you have to query
the view dba_ind_columns so you have to be a sysdba user
but I don't want to grant the application developers the sysdba privilage
but my friend told me , to avoid grant sysdba to the application developers, they can query the view user_indexes in their schema, but after watching the view user_indexes ,
it gives me a lot of data but doesn't give me the COLUMN NAME
how can I solve this problem which is :
Allow the application developers to check for index existing for certain column in their schema without granting them sysdba privilage.You can use that query:
select ai.index_name INDEX_NAME,
substr(ic.column_name, 1, 30) COLUMN, ic.column_position POSITION,
ic.table_name TABLE,
ai.tablespace_name TABLESPACE
from all_ind_columns ic, all_indexes ai
where ai.index_name = ic.index_name and ai.table_name = 'TABLE_NAME' and ai.table_owner='OWNER' -
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 Thanks1) Why are you using Threads?
2) It is preferrable to implement Runnable.
3) This is all incredibly pointless (see point 1) -
Is there any tools can check for existed database ?
hi all, is there any tools that can check for that existed database after inserted a database to Ms access??
Then you'll open a connection and then do a Select from table to retrieve information. (and close afterwards)

Checking for files in a folder -- Wrong output
Hi guys,
I'm writing a simple program, I have to check for 6 files (hardcoded, they will never change) if they are in certain directories/paths.
The problem is, I think I have a problem in my IF statements, because it continueally returns false.
The paths are on networked drives, does that make a difference?
I'm rather stuck on this one, any help would be appreaciated.
(some paths/file names have been replaced by "xxxxxxxxx", for security)

FileCheck window = new FileCheck();You could try using the File.exists() method.
The paths are on networked drives, does that make a difference?Try the above on a local file and a networked file.
I'm writing a simple program, Actually a simple program would be something like:
File file = new File("xxx");
System.out.println(file.exists());No need to include all the code you posted.

Any way to check for errors in an external table besides the log?
For example if you have an external table where a column is defined with a CHAR(1) but when you run a SELECT on it, the mapping comes up with trying to put a CHAR(2) into that single space. The only way I'm aware to see if something is wrong is to check the .log file. Is there any other way to check for an error message or count?
I'm mounting external tables and copying data over to a 'holding' table to be able to work on the data before it's moved into the actual production table with PL/SQ code. If the stored proc can determine what rows are bad or missing or even that there just are some rows with problems then hand back to the app, it would greatly improve things.
Thanks.No other way than to check for the existance of a .bad file, then have a look see at the .log then?

File exist to check for any file, not just a specific filename
How can I implement a check to see if any file exists in a certain directory. I don't know the filename beforehand, only the directory.
Can I still use the FILE EXISTS activity or do I need to write something different.
Thanks,
GuidoHi guidonlm
You can use USER DEFINED activity or FILE EXISTS activity. With file exists you must get file name before (file name can be hard coded or passed as variable). With user defined activity you can make your own shell script and check anything that you need (in this case you must enable property in file $ORACLE_HOME/owb/bin/admin/Runtime.properties property.RuntimePlatform.0.NativeExecution.Shell.security_constraint = NATIVE_JAVA

How can I check for directory creation?
Hi,
I want to check whether I can create a directory at a particular location.
Let's say at c:\windows, can create a directory called c:\windows\mydir. But I won't be knowing the parent location (i.e., c:\windows here) at compile time.
And I would also like to check for creating a directory like c:\windows\mydir1\mydir2 (mydir1 may not even exist).
What I was doing was, I created the file object for my new directory (i.e., mydir here) and used the canWrite() method on the parent directory. But this method worked only when the parent directory existed. But how can check for a directory path like c:\windows\mydir1\mydir2 where I have to create both mydir1 for mydir2.
Is there any other methods that I can use to perform this kind of a check.
Thank youI finally figured out a workaround, but i don't know whether this is a good way of checking. :)
import java.io.File;
public class TryMKDIRs {
public static void main(String[] args) {
File file = new File("c:\\mydir1\\mydir2\\mydir3");
boolean canICreateDir = false;
if(false == (canICreateDir = file.canWrite())) {
System.out.println(file.getAbsoluteFile() + " cannot be created.");
File fileparent = file.getParentFile();
while(fileparent != null && (canICreateDir = fileparent.canWrite()) == false) {
System.out.println(fileparent.getAbsoluteFile() + " cannot be created.");
fileparent = fileparent.getParentFile();
if(canICreateDir) {
file.mkdirs();

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,

Well, this has been going on for a long time and I've had my absolute fill of it tonight.
I have purchased a large collection of movies from iTunes that for mainly the reason that I have a new computer, my old films no longer exist as downloaded iTunes videos. That being said, I know I should be able to download purchased films as long as they're still on the iTunes store. I cannot download any of them. Tonight I decided to buy a collection that should have allowed me to download all three films (which I had previously owned, but got sick of trying to find a solution to why I cannot redownload them). So tonight, I purchase this collection of three films, downloads the frst one. Theres absolutely no sign of the second or third film and when I select Check for available purchases it says all available purchases have been downloaded.
If this was true, 25+ movies would be available to download, least to say the two missing from tonights purchase (which I have purchased in the past as well).
My account is authorized, everything is alright with my account and I have tried multiple suggestions and am completely lost. Apple support is giving me the run-around.
What do I do?Nevermind. I finally found a third party answer and will post it for anyone else with my problem.

HI
i restored a sharepoint web 80 application in our test domain
and after when i browse the new web application
it says
Cannot make a cache safe URL for "1025/styles/Themable/corev4.css", file not found. Please verify that the file exists under the layouts directory.
adilHi adil,
According to your description, my understanding is that you encountered the error “Cannot make a cache safe URL for "1025/styles/Themable/corev4.css", file not found. Please verify that the file
exists under the layouts directory.” .
The issue happens in
We have customized master page
In the master page, we use path the script/style file like this: <SharePoint:CssRegistration name="<% $SPUrl:~SiteCollection/Style Library/coe/mainCOE.css%>"
runat="server"/>
While using the dynamic path in a multiple languages enabled site, language Id(1033 etc) will be added to the path automatically. That cause the file to be not found.
To solve the issue, please download the Arabic language pack http://www.microsoft.com/en-us/download/details.aspx?id=3411 ,
install it on your SharePoint and refresh your browser.

SundharHi Sundhar,
According to your description, you might want to check the existence of sub folder in a folder of a library using Client Object Model.
Please take the code demo below for a try, it will check whether there is sub folder in a given folder:
public static void createSubFolder(string siteUrl, string libName, string folderServerRelativeUrl)
ClientContext clientContext = new ClientContext(siteUrl);
List list = clientContext.Web.Lists.GetByTitle(libName);
CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml =
@"<View Scope='RecursiveAll'>
<Query>
<Where>
<Eq>
<FieldRef Name='FSObjType' />
<Value Type='Integer'>1</Value>
</Eq>
</Where>
</Query>
</View>";
//camlQuery.FolderServerRelativeUrl = "/Lib1/folder1";
camlQuery.FolderServerRelativeUrl = folderServerRelativeUrl;
ListItemCollection items = list.GetItems(camlQuery);
clientContext.Load(items);
clientContext.ExecuteQuery();
Console.WriteLine(items.Count);
if (0 == items.Count)
//create sub folder here
