When loading large number of images, images begin to fail to load in IE11 with DOM: 7009 error (unable to decode) in console
When loading many images on a single page in IE (reproduced in IE11), some of them begin to fail to load, and have something similar to the following warning in the console:
DOM7009: Unable to decode image at URL: '[some unique url]'.
When I look at the network traffic, there does appear to valid responses received for each of these images from the server. It's not always the same images each time. If I use the dev tools to force the image to reload (example: I update the url to include some some extraneous url parameter "&test=1"), it loads/renders normally without error. I've reproduced this behavior with different types of images (jpegs/pngs; example png included below). Apologies for the cross-posting. I wasn't sure what the particular etiquette was for that - I've also posted this issue on StackOverflow and MS Connect under the same title. If one of those is a more appropriate place for this matter, please let me know and I'll close this issue.
yup, i have encountered this problem as well. I'm loading an array of image frames for a movie, and i'm using preloadJS (javascript preloading library) and not displaying the images upfront.

Question?
I have accidentally deleted a large number of develped images in Lightroom before I did a backup. I reimported the original raw files back into Lightroom hoping the develop settings would be re-established but no luck. Notice system mau have done an auto-backup as have an lrcat-journal file. Can I use this to restore my develop settings. I also have jpgs generated from all the deleted images.Hello,
if you have a backup of your catalog you can do the following:
1. Backup your catalog first
2. Restore your backup catalog to some location
3. Open your current catalog and select "files->import from another catalog".
4. Select your backup catalog and your lost images. LR ask you if you want to overwrite the current settings or save them as a virtual copy.
As an alternativ you can open your backup catalog, select the "lost" images and save the development settings as xmp sidecar fiels (using ctrl-s). Then open your current catalog, seletct the images and use "Metadata->Read Metadata from files". -

Loading large number of coordinates
Hello,
We are trying to load the SDO_ORDINATES columnobject of the SDO_GEOMETRY column in a spatial feature table with a large number of coordinates (4844). This is not the largest linestring we will need to build. We have defined a procedure as:
CREATE OR REPLACE PROCEDURE
INSERT_GPS(GEOM MDSYS.SDO_GEOMETRY) IS
BEGIN
INSERT INTO GPS(long_lat_elv) VALUES (GEOM);
COMMIT;
END;
and are loading the SDO_GEOMETRY column as follows:
DECLARE
myGEOM MDSYS.SDO_GEOMETRY := MDSYS.SDO_GEOMETRY(3002,NULL,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,2,1),
MDSYS.SDO_ORDINATE_ARRAY(
-86.929501,35.751834,32.907,
-86.929434,35.751906,32.913,
87.270367,35.447903,.854,
87.270273,35.447956,.86
BEGIN
dave_insert(myGEOM);
END;
This generates the following error:
PLS-00123: Program too large.
How can we load this many coordinates, using this workflow? We are using 8.1.6.
Thanks

Why don't you use SQL*Loader to load the data? We have geometries which have more data than yours and sqlloader didn't have any problems.
I believe PLS-00123 means that your package is too big.
What else do you have in your package?
Try and break the package in more smaller ones.

Telim,
We are trying to use the LRS package and the measure value, which is part of the coordinate (x,y,m) has to be generated from a stored procedure for each x,y pair.

MBPro crashes when transfering large number of files
i have a MBPro 2008 and recently when i transfer a large number of video files [over 5GB] my computer will suddendly crash in the middle of the transfer.
i'm usually not using it while its transfering. This is a very recent problem.
Sincerly,
stef./.\How large is you HD and how much space do you have left?
Try the following:
Disconnect all devices from the computer then do the following:
Boot up from your Snow Leopard Install DVD while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius. -
Making a 'Movie' from large number of 'still images?'
I have a 2011 15" MacBook Pro with Lion. I have QuickTime Player 10.1.
I want to make a 'movie' showing our new company product rotating on its axis. The raw material would be still images, each taken from a slightly different angle. I thought QuickTime Pro would be the tool for this, but apparently it no longer exists? Can I accomplish the same thing in iMovie?
Suggestions most welcome.
Thank you!
Chris in New HampshireThank you, AppleMan! I just wanted to make sure that I'm OK buying this because the App Store tells me this as a warning:
Please note: Your QuickTime 7 Pro registration code only works with QuickTime 7. Be sure you have downloaded and installed QuickTime 7 Player before you enter your QuickTime 7 Pro registration code.
So, since I have QuickTime Player 10.1 I wanted to confirm that this isn't a roadblock. -

Managed ODP: InvalidCastException when returning large number
I get an InvalidCastException "Specified cast is not valid" when trying to get a value bigger than Decimal.MaxValue as a scalar result from a select.
From the stack trace and inspection of the Oracle.ManagedDataAccess.dll code I would expect OracleDataReader to cast to OracleDecimal (or System.Numerics.BigInteger) instead of System.Decimal for large numbers.
Is this a bug?
Stack trace:
at Oracle.ManagedDataAccess.Client.OracleDataReader.GetDecimal(Int32 i)
at Oracle.ManagedDataAccess.Client.OracleDataReader.GetValue(Int32 i)
at Oracle.ManagedDataAccess.Client.OracleCommand.ExecuteScalar()
at Cora.Data.DBProvider.Tests.CoraParameterTest.BigIntegerOracleTest() in D:\svnroot\tech\lib\Cora.Data.DBProvider\Cora.Data.DBProvider.Tests\CoraParameterTest.cs:line 98
How to reproduce:
- create a table NUNITTEST_PARAM_SIMPLE with a column BIG of type NUMBER(38)
- run sample code
using ( OracleConnection conn = new OracleConnection(ORACONN) )
conn.Open();
using ( OracleCommand cmd = conn.CreateCommand() )
cmd.CommandText = "insert into NUNITTEST_PARAM_SIMPLE (BIG) values (1234567890123456789012345678901234567)";
cmd.ExecuteNonQuery();
using ( OracleCommand cmd = conn.CreateCommand() )
cmd.CommandText = "select BIG from NUNITTEST_PARAM_SIMPLE";
object result = cmd.ExecuteScalar(); // Exception
conn.Close();There is no safe type mapping for ExecuteScalar. It's an uncommon use case.
Even if there was, making the correct conversion implicitly would lead to more work for the application developer. Let's assume ODP.NET performs the "right" conversion. Now, the app needs to manipulate the data. What data type does it treat the returned value as: string or decimal? It could be either. That means twice as much code. One set deals with the data if a decimal was returned. The second deals with the data if a string is returned.
It would be much easier to write code for one scenario, rather than two. That is why ODP.NET safe type mapping is an explicit conversion the developer makes. -
Error "java.lang.OutOfMemoryError" When Returning Large Number of Docs
In our SES implementation, we have a custom search interface that allows users to search for documents and then add them to a "shopping cart". Users add then to their shopping cart from search results, by adding docs one-by-one or an Add All option. Once they are done "shopping" they create a report.
Here is the scenario...
Users are saerching for documents and seeing that on page 1, there is 1 - 10 of about 300 results. They clicked Add All and want all 300 docs added to their cart.
What we do under the covers is we execute another search and set the docs requested to 200. We get the array of docs, iterate over them and add the keys to a list. We found 200 docs at a time to be a safe number. However, there are still 100 docs that were not added to their cart and users want all 300 added. In other words, when they click Add All, they want to add all docs, 300, 500, 5000, etc.
I set the "Maximum Number of Results" to 500 and found that I can safely add up to ~ 350 docs at one time. However, going past this point throws the following error:
[SOAPException: faultCode=SOAP-ENV:Server; msg= [java.lang.OutOfMemoryError]]
at oracle.search.query.webservice.client.OracleSearchService.makeSOAPCallRPC(OracleSearchService.java:941)
at oracle.search.query.webservice.client.OracleSearchService.doOracleSearch(OracleSearchService.java:469)
After this error is thrown, SES was unable to recover and searching would not work anymore, even return 10 docs at a time. We had to restart SES to resolve the issue.
1. What is throwing this error? Is it the amount of XML being returned?
2. What is the maximum number of results we can get back at any one time? Is it based on the amount of data being returned or the number of attributes?
We are running 10.1.8 with plans to upgrade soon.
Thanks in advance.I know it may be hard to throw away all this code, but consider using the jakarta fileupload component.
I think it would simplify your code down to
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
List /* FileItem */ items = upload.parseRequest(request);
// Process the uploaded items
Iterator iter = items.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
if (item.isFormField()) {
processFormField(item);
} else {
// item is a file. write it
File saveFolder = application.getRealPath("/file");
File uploadedFile = new File(saveFolder, item.getName());
item.write(uploadedFile);
}Most of this code was hijacked from http://jakarta.apache.org/commons/fileupload/using.html
Check it out. It will solve your memory problem by writing the file to disk temporarily if necessary.

ActiveX Printer Error when print large number of page
Hi,
I have this problem when developing the report on my project.
I developed the Crystal Report embedded in Visual Studio 2008 to be displayed in web form.
I'm using .NET and the operating system of the development computer is Windows 7 32 bit.
The problem is, I have a quite complex report displaying the statement for the customer which is result in 209 pages.
When the report has successfully loaded, I simply click the print icon and it comes up with the error "A communication error occurred. Printing will be stopped"
But, after that...I tried something different, when the report has successfully loaded, I went through the report by moving for every 30 pages until it reaches the last page and click the print icon. and it prints without any errors!
Anybody knows what caused this?
By the way, I'm using the ActiveX printing mode for the Crystal Report.
Thanks
-Marry-I'm thinking there is something not processed in the report so forcing the report to process everything up to the last page before printing may help. Try the following code before sending the report to the viewer:
Dim prc As New CrystalDecisions.Shared.ReportPageRequestContext
rptDoc.FormatEngine.GetLastPageNumber(prc)
This may slow down the time it takes for the report to come up as the whole report will need to be processed, formatted, etc.
Also, make sure you have SP 1 for CR 10.5:

Lightroom problems with large folders of Raw images
I have a problem processing folders with a large number of Raw images in Lightroom and the same folder is easily processed in Adobe Bridge (without much loading time). The folder locked up Lightroom more than once. The folder has Nikon D2X and D2H .NIF files and it has 850 images. I bought Lightroom to simplify the editing and sorting and sorting process but I often work out of large folders like this. Is Bridge a better answer for what I am looking for or am I doing something wrong (like not waiting long enough).
It can take some ime for LR to import a large folder of RAWs. But once in it should be faster.
How are you importing. Are they already on your HD, or coming from the camera with copy, or a cardreader?

Large number of movieclip slowdown the application
Hi,
I have a scrollbar function.In the content area i attached movieclips.Those moviclips have dynamic textfield.The scroll bar working for small list of contents.up to 500 or 600 moviclips
When i attached 2000 or larger number of movieclip the Entire flash get slows. How to i fasten them with same number of movieclip.
why flash player slow when attaching large number of movieclip? it takes near by 58% cpu usage at this time.What is the reason for this?
Thanks,
Sivaimm also if you put much media inside the flash library (Audio,images, videos) those will be uploaded on Ram,,,
so instead you can export your library as external library
or
use AS3 loader to load your media, immutablility will be fine here!! ^_^

Best way to delete large number of records but not interfere with tlog backups on a schedule
Ive inherited a system with multiple databases and there are db and tlog backups that run on schedules. There is a list of tables that need a lot of records purged from them. What would be a good approach to use for deleting the old records?
Ive been digging through old posts, reading best practices etc, but still not sure the best way to attack it.
Approach #1
A one-time delete that did everything. Delete all the old records, in batches of say 50,000 at a time.
After each run through all the tables for that DB, execute a tlog backup.
Approach #2
Create a job that does a similar process as above, except dont loop. Only do the batch once. Have the job scheduled to start say on the half hour, assuming the tlog backups run every hour.
Note:
Some of these (well, most) are going to have relations on them.Hi shiftbit,
According to your description, in my opinion, the type of this question is changed to discussion. It will be better and
more experts will focus on this issue and assist you. When delete large number of records from tables, you can use bulk deletions that it would not make the transaction log growing and runing out of disk space. You can
take the table offline for maintenance, a complete reorganization is always best because it does the delete and places the table back into a pristine state.
For more information about deleting a large number of records without affecting the transaction log.

Hope it can help.

But there is a node and is found while processing in a java program for the same xml file. But this occurs when a large number of request comes.
Please suggest.Yes I parse xml as much as the request comes. and i do not want to synchronize here. The below code executes for each request. Do we have a solution here .
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document configXML = docBuilder.parse(filePath);
I have tried with DOMParser and follwowing method is applied
setFeature( "http://apache.org/xml/features/dom/defer-node-expansion ",false).
Please suggest.
