Identifying modified data and prevent a second submit in a page

I'm having two problems.
The first one is how i can know if a user modified the data in a form, when he is passing from a tab to another? because if he has modified anything, i need to ask if the data will be saved or the changes will be discarted.
The second one is to prevent a user if he tries to click again in a button, until the response arrives, prevent a form's second submission. I've tried to use the block attribute of the commandlink and commandbutton, but it doesn't work.
Thanks

"One other issue that we faced was how to determine whether the page had unsaved changes, or was "dirty," in colloquial terms. It would sure be a pain to have to compare each field's value with the database to determine if the record was dirty. After playing around, we noticed something... if you drop a commit button from the data control palette on to your page, by default it is only enabled if there are changes that need to be saved... hmmm... that looks like some behavior we could use. In that commit button, the "disabled" property is set to "#{!bindings.Commit.enabled}" so it turns out we can use that EL expression to determine if there are changes to save or not. The only requirement is that each page needs to have a Commit action binding"

Force Crawler in Maint Mode to Ignore Last Modified Data and Re-Index All

We are running SES 10.1.8.4 with the Siebel 7.8 data source patches 8533402 and 8624308 to index documents (PDF, XLS, DOC, PPT) via RMI and Decompression Tool in Siebel. This data source is virtually identical to the database data source.
The crawler will not "fail" if the actual indexing of the attachment file itself fails. For example, if RMI is down on the Siebel server and the crawler runs, SES will index the document metadata returned in the SQL but not the document. If the client then starts the RMI utility and re-runs the crawler, the document that was not indexed will not be re-indexed because the data source's last crawl time is used against the data sources last modified date attribute.
Here is the pseudo SQL for the initial crawler query in maintenance mode....
SELECT .... FROM MY_VIEW WHERE LASTMODIFIEDATE > TIME OF LAST DATA SOURCE CRAWL
We have found a way to update the data source's last crawl time (DS_LAST_CRAWL) in the EQ$_DATA_SOURCE table. For now, we simply are using SYSDATE - 1.
This will allow the missed document to be returned in the initial query.
However, it's the crawler's document-level last modified date check within the crawler that is preventing the re-index. Since the document's last modified date is the same as what SES has, SES skips over it thinking it has not changed. True, it has not changed but it was missed during the last re-crawl and we want it to be indexed again.
The client does NOT want to perform a full re-index because of the anticipated volume of attachments.
Is there any way to tell the crawler to ignore the document-level last modified date and re-index everything returned from the initial query? Perhaps one of the other columns in the EQ$_DATA_SOURCE (DS_STATUS, DS_CRAWLING_MODE) holds the key?
Thanks!

I think it might be possible to set ENQUEUE_STATUS = 'Y' in the table EQ_TEST.EQ$URL. You may need to call eq_adm.use_instance(1) before doing so.
However I'm not sure of the full implications of doing this - DON'T DO IT ON A PRODUCTION SYSTEM without carefully testing on a development system.

How to get last modified date and time of a file which is in apache server.

Hi ,
I need to get last modified date and time of a file in remote machine.
This file is in remote machine which has apache server installed.
I am trying to get this information by connecting to apache server from client by giving absolute URI of the file to file object.
URI is got from apache server URL by using toURI method.
when I use lastModified method , its throwing exception , because scheme of URI is not file.
I can't give scheme as file because ftp server is not installed on that server
Is there any other way to get this information .

No, unless you can use an FTP client.

I am trying to organize thousands of images in aperture. The dates on the old scanned images is all 2008, when I started importing them. When I change the date in aperture some of them hold the modified date and some revert to 2008. Any ideas?

I am trying to organize thousands of old images in aperture. Aperture dates them all in 2008, when I started this project. When I change the date in aperture some of them hold the modified date and some revert to 2008. Any ideas?

I just tried a test library, re-imported fresh images from a hard drive, and the date changes still revert.
So neither your external drive nor your Aperture library are to blame.
What do you mean test in a different user acct? Would it be a good idea to uninstall and re-download aperture 3?
Appreciate all your help.
I meant the trouble shooting procedure described here: Isolating an issue by using another user account
To test, if some settings in your user account are faulty or preferences files corrupted, it helps to create a new user account from the "Users&Groups" System preferences. With a brand new user account you can see, if something in your current account is causing this.
Should you see, that Aperture is not even working from a new and clean account, I'd reinstall Aperture, and if need be the Operating system. Are you using any plug-ins?

Get File by modified date and extension then copy to location

Hello,
Ill give a brief description of what I am trying to accomplish. We have a bunch of files that are sitting on a deduplication box (Exagrid), we want to try and copy certain files off of this dedup box, however, if we copy EVERYTHING this will fill up our
entire NAS Device. So, instead, I need to build a script that finds files by a modified date and extension type, then copy those to a specified folder.
Here is the code:
$logfile = "C:\CopyResults.log"
function LogWrite{
Param([string]$logstring)
Add-Content $logfile -Value $logstring
$date = get-date
$DateToCompare = (Get-Date).AddDays(-2)
$Files = Get-ChildItem -Recurse | Where-Object {$_.LastWriteTime -gt $DateToCompare} | Where-Object {$_.Extension -eq ".xlsx"}
foreach($File in $Files){
Write-Host "$File was copied to C:\test"
Copy-Item $File C:\test
logWrite "$File was copied to c:\test --- $date"
The file extension is of course just a test, as well as the destination of where these files are to be copied to. Ultimately I would like to build in the functionality that will check the date and delete the files after a certain amount of time has passed and
then copy new files. For now, though, I would be satisfied with just some insight on my own idea and know where I am going wrong or how to clean this up a little better. The overall issue I having is when I run this portion of the script I get this: Copy-Item
: Cannot find path 'C:\Users\<username>\<filename>.xlsx' because it does not exist.
At line:13 char:5
+ Copy-Item $File C:\test
+ ~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (C:\Users\<usern...al filename>.xlsx:String) [Copy-Item], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.CopyItemCommand

I solved the issue. Here is the full script:
net use \\netpath\filename /user:<Username> <Password>
$logfile = "C:\CopyResults.log"
function LogWrite{
Param([string]$logstring)
Add-Content $logfile -Value $logstring
$date = get-date
$DateToCompare = (Get-Date).AddDays(-1)
$VBMs = Get-ChildItem \\netpath\filename -Recurse | Where-Object {$_.LastWriteTime -gt $DateToCompare} | Where-Object {$_.Extension -eq ".vbm"}
$VBKs = Get-ChildItem \\netpath\filename -Recurse | Where-Object {$_.LastWriteTime -gt $DateToCompare} | Where-Object {$_.Extension -eq ".vbk"}
$VIBs = Get-ChildItem \\netpath\filename -Recurse | Where-Object {$_.LastWriteTime -gt $DateToCompare} | Where-Object {$_.Extension -eq ".vib"}
foreach($VBM in $VBMs){
Write-Host "$VBM was copied to C:\test"
Copy-Item $VBM.FullName \\netpath\filename
logWrite "$VBM was copied to c:\test --- $date"
foreach($VBK in $VBKs){
Write-Host "$VBK was copied to C:\test"
Copy-Item $VBK.FullName \\netpath\filename
logWrite "$VBK was copied to c:\test --- $date"
foreach($VIB in $VIBs){
Write-Host "$VIB was copied to C:\test"
Copy-Item $VIB.FullName \\netpath\filename
logWrite "$VIB was copied to c:\test --- $date"
"In this case you are handing a System.IO.FileSystemInfo.FileInfo object to the Copy-Item cmdlet. I think the cmdlet is probably defaulting to using the .Name property and that is not enough information for the copy to work. When you explicitly give the
.FullName property to the cmdlet, it now has the information that it needs."
I found this on Stack Overflow buried in the forums and it resolved all my issues. I have tried using that tool and it works very well, however, Powershell is what I am using for everything and I would like to keep it that way.
Thank you all for your time and help.

How to find the Last modified date and time of a package

Hi,
We need a clarification on how to find the Last modified date and time of a package in Oracle. We used the example below to explain our scenario,
Lets consider the following example
Let A, B be two packages.
Package A calls the package B. So A is dependent on B.
When A is compiled the TIMESTAMP,LAST_DDL_TIME in USER_OBJECTS gets updated.
Now there a modification in package B so it is compiled. There is no modification in package A.
Now when the package A is executed the TIMESTAMP,LAST_DDL_TIME in USER_OBJECTS gets updated but we did not make any change in Package A. Now we need to find last modified date and time of the package A . So we can not rely on the TIMESTAMP,LAST_DDL_TIME in USER_OBJECTS . Can u please tell us any other solution to get last modified date and time of the package A .
Regards,
Vijayanand.C

Here is an example:
SQL> SELECT OBJECT_NAME,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS FROM USER_OBJECTS
2 WHERE OBJECT_NAME = ANY('A','B');
OBJECT_NAM CREATED LAST_DDL_TIME TIMESTAMP STATUS
A 20-MAY-2004 10:57:32 20-MAY-2004 10:57:32 2004-05-20:10:57:32 VALID
B 20-MAY-2004 10:58:22 20-MAY-2004 10:59:04 2004-05-20:10:59:04 VALID
SQL> CREATE OR REPLACE PROCEDURE A AS
2 BEGIN
3 NULL;
4 NULL;
5 END;
6 /
Procedure created.
SQL> SELECT OBJECT_NAME,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS FROM USER_OBJECTS
2 WHERE OBJECT_NAME = ANY('A','B');
OBJECT_NAM CREATED LAST_DDL_TIME TIMESTAMP STATUS
A 20-MAY-2004 10:57:32 20-MAY-2004 11:01:28 2004-05-20:11:01:28 VALID
B 20-MAY-2004 10:58:22 20-MAY-2004 10:59:04 2004-05-20:10:59:04 INVALID
SQL> EXEC B
PL/SQL procedure successfully completed.
SQL> SELECT OBJECT_NAME,CREATED,LAST_DDL_TIME,TIMESTAMP,STATUS FROM USER_OBJECTS
2 WHERE OBJECT_NAME = ANY('A','B');
OBJECT_NAM CREATED LAST_DDL_TIME TIMESTAMP STATUS
A 20-MAY-2004 10:57:32 20-MAY-2004 11:01:28 2004-05-20:11:01:28 VALID
B 20-MAY-2004 10:58:22 20-MAY-2004 11:01:53 2004-05-20:11:01:53 VALID
Note that the date under the column 'created' only changes when you really create or replace the procedure.
Hence you can use the column 'created' of 'user_objects'.

How to autofill the Modified Date And Modified User?

hi All,
Below is the screenshot of my form , if we look at the last 4 columns we have Created Date,Created User Id which is popped up automatically if a new entry is being created. Now if we look at the last 2 ModifiedDate and ModifiedUserId those fileds will be
empty wile creating a new entry which is good for me. But lets say if i go back to any existing record and want to modify it then the modified date and modified userid must be popped up with that persons name and current date. I think i can use the logic i
have to get date and userid but i want some help with code to how to make the modified fields fill up.
Can someone please help me with this?
Thanks a lot for all your time and support.

well I use it all the time, and have no problem in that initially both the 'started' and the 'modified' date fields have the same value..... because when one is editing a record whether initially putting in data or adding/changing later - they are both considered
to put the form in a dirty state.
then in future edits only the modified date field changes. the code in the OnDirty event is:
me.ModifiedDateFieldName=Now()
any other approach will be more difficult to achieve as essentially one must trigger it not universally at the OnDirty event but something more specific such as at every control

Identify modified date/time and name of SOURCE file

I can't seem to find a way to store/retrieve the last-modified date/time of the SOURCE file (as well as filename) used to create a PDF. I looked into the default metadata, but it seems to store only the last-modified date of the PDF.

I'm sorry, maybe I'm a little slow, but I would need more detailed specs on how to solve the problem. Is this something you have implemented yourself? If so, how?

GOOP VI "set modified data" locks LabVIEW for seconds

I use GOOP.
Sometimes the VI "set modified data" (from now on SMD) of one of my GOOP classes is locked for about 15 seconds, while CPU raises to 100%.
It happens when SMD is called from a certain VI. It does not happen every time SMD is called from this VI.
As I have understood GOOP, the VI "get data to modify" tries to access/lock the data members - which might take a while if the the data members are currently locked by another VI - but SMD only sets the data members and removes the lock, which should always be possible (at least if the data set has been locked by this VI, which - yes! - is the case).
Other VIs are running in parallell, maybe they could cause the CPU to raise to 100% but I find it strange th
at it only happens when SMD is called from this particular VI.
I think I need a better understanding for how SMD really works.
Regards

Hi,
Your description of how "get data to modify" (from now on called GDM) and "set modified data" works is correct and you have fully understand how it all works. The only VI that actually may wait is the "get data to modify" (happens if the data for the object is locked by something running in parallell as you describe). The GDM is however reentrant so that it really will be able to wait for seconds (specified by the timeout) and also letting other process wait as well using the GDM. The SDM is not reentrant (does not have to) and should really execute fast (set data and unlock) and never hold execution, just as you describe.
Are you absolutly sure that it is the SMD that cause the CPU to freak out? Maybe the fact that you unlock the data releases ano
ther part of your program that were "hanging on the lock" and the problem is actually in another part of the program. Do you have some exceptional large size of your data? Do you somehow elaborate with VI priorities and/or reentrant VIs. This might sometimes really cause strange situations. The situation you describe looks more like a "race" problem.
The SDM problem you describe is new to me and I have never encounted it. Would it be possible for you to attach some LV code example showing the phenomenon?

Howto: comparing 2 dates and getting the seconds

By comparing 2 dates I need to extract or get somehow the elapsed seconds. I need to get only
the seconds.
Dates are in this format "hh:mm:ss"
I tried with Date and GregorianCalendar but I couldnt get the desired result.
Can someone provide me with a sample code please.

Its not broken, nor absurd or complicated. I only need resolution only for minutes. The method that I use does not need to know more than 20 seconds.
But I added minutes knoledge aniway. As you can see its easy to add hour resolution if needed. But I didnt needed it so thats why I took that approach.
This looks cleaner for you? I just wrote it here, untested, but should work.
public int returnSeconds(Calendar c1, Calendar c2)
int mins = c1.get(Calendar.MINUTES) - c2.get(Calendar.MINUTES);
int secs = c1.get(Calendar.SECONDS) - c2.get(Calendar.SECONDS);
if (mins > 0) return secs+=mins;
else return secs;
}And why should I treat all the time as miliseconds since the epoch. Thats an absurd afirmation without a detailed explanation.
Edited by: remus.dragos on Apr 30, 2008 6:18 AM- Unnecessary creation of expensive Calendar objects.
- Significantly slower
- Breaks across Timezones
- Unnecessary decision making introduces complexity
- Introduces a bug by assuming c1 represents a time greater than c2
- Introduces a bug by not multiplying minutes by 60 to obtain seconds.
- Makes assumptions about the calendar system in use
- Less maintainable because it limits the scope of time unit resolution handled by the logic
I probably missed some more too. None of this is needed, and it is very brittle. Your problem can be solved by subtracting one fixed-point number from another. Go with es5f's approach.

Query to find universe modified date and modified by

Hi,
Is there a way we can query to find universe last modified by and modified date?.
I was not able to find a field to pull "modified by" info.
Thanks

Sreedhar,
I'm not exactly sure how you're going to get from Point "A" to Point "B", but here are the two points:
a) using QB you can perform a search as was specified in my last posting, which you point out only provides "owner"
b) if you have the Auditor portion running, then in the Audit_Detail table is the column "Detail_Type_ID" and each time a universe is accessed a code "2" is recorded and Detail_Text is loaded with the Universe name. If you join the Audit_Detail table to the Audit_Event table on Event_ID, then you'll have access to User_name and Start_Timestamp, which will show you who and when a Universe was accessed.
Thanks,
John

Get last modified date and time of sharepoint site through Search

Hi All,
I am trying to get the last updated date and time of a sharepoint site using KeywordQuery.
For this I updated an existing list item, added a new item in a site and crawled the content. Then I used "ContentClass:STS_Site" as query in C# code to fetch the search results. I am able to get most of the properties I require for that
site. However "LastModifiedTime" does not return the correct value. It returns an older value.
How can I get the last updated date of a sharepoint site using search ?

Place the tabular data and it's corresponding graphic into one page?

We know that BEx Analyzer seems not be able to place tabular data and it's corresponding graphics like pie chart into one page. Could someone yield detailed technical steps on how to realize this?
Thanks!

Hello Kelvin,
As responded above, Yes it is possible to show both in a single page using the Drop down option you would find in the web report.
And in case you want to see both table and graph in a single page for all the reports by default, then you may want to edit the standard web template that is being used to all the web reports (most possibly 0ANALYSISPATTERN) to change the deafult settings for this drop down box.
