When to use collection?
Sorry to post such question in this forum , but i would like to recieve some interesting about this .
I know the basics of collection but i dnt know when to use which one?
I am totally confused that all are working for the same thing with little difference .
Please suggest me some tutorial if do u have .
Thanks in advance .
Hope u will realize my problem.
I am totally confused that all are working for the same thing with little difference .Ahh - but those little differences can be important.
Basic rules
1 - First decide if you need a List, Map or Set.
2 - If it is List, probably use ArrayList
3 - If it is a Map, probably use HashMap
4 - For a Set, probably use HashSet.
That covers 90% of the base cases. Most of the time you just need those base classes.
As always there are the exceptions
- If you are constantly reading/adding/removing from the ends of the list, and not accessing the middle, consider using LinkedList implementation.
- If you want your Map to be ordered by key (like a dictionary for example), then TreeMap
- If you want your Map to retain the order they were inserted, then LinkedHashMap
Yes the differences are subtle between versions, but those subtleties can be important.
However in most cases, you can just use the stock standard base class.

When I first started using Collections, I followed someone's advice and always clicked 'create virtual copy' -- so I now have a huge number of unused/useless VCs that I would like to clear out. Is there any way to 1) filter to show all virtual copies that have not been changed (but keep the ones that I have edited or changed in any way, 2) delete the unchanged virtual copies but keep the collection that holds them intact? I can picture a work-around for the second part by color coding all the unused VCs along with their original, deleting the unedited VCs, going to the folder and selecting all the colored originals, dragging them to the colection and then removing the color lable. Cumbersome, but doable.
Umm no not that i remember. It just randomly started happening. I reformatted the hard drive for mac (journaled) but it was working fine since i did it until now

Occasionally, some of the image borders turn dark grey (medium grey is the default) and then random other images cannot be opened with a double click. They only open when selected using the arrows on the keyboard. They also cannot be moved to collections. Anyone have a solution for this?
When you say "could not be opened"- what are you referring to? A double click of the mouse should view the clicked image in Loupe view- the same as pressing [E] on the keyboard for an enlarged view. (And a second double-click will take you back to library grid view.)
To "open" an image in the Development module requires you to select the image then press [D] or click on the [Develop] button.
When you say "could not be ...moved" -what are you referring to? Are you trying to move an image file from its place in a folder to another folder? Are you just wanting it in a collection? When you drag an image to a collection you are only placing a link to the image in the collection- not actually moving any file. The image will stay exactly where it is in its original folder and will remain as a thumbnail preview in the Library Grid view.
Are you having any "mouse" problems that may be changing its actions in LR ?
Do you see an exclamation mark on any image borders ?
Let's keep working on this. I am curious to see you find an answer.

Best practices when using collections in LR 2
How are you using collections and collection sets? I realize that each photographer uses them differently, but I'm looking some inspiration because I have used them only very little.
In LR 1 I used collections a bit like virtual Folders, but it doesn't anymore work as naturally in LR2.
In LR 1 it was like:
Travel (1000 images, all Berlin images)
Travel / Berlin trip (400 images, all Berlin trip images)
Travel / Berlin trip / web (200 images)
Travel / Berlin trip / print (100 images)
In LR 2 it could be done like this, but this somehow feels unnatural.
Travel (Collection Set)
Travel / Berlin trip (CS)
Travel / Berlin trip / All (collection, 400 images)
Travel / Berlin trip / web (collection, 200 images)
Travel / Berlin trip / print (collection, 100 images)
Or is this kind of use stupid, because same could be done with keywords and smart collections, and it would be more transferable.
Also, how heavily are you using Collections? I'm kind of on the edge now (should I start using them heavily or not), because I just lost all my collections because I had to build my library from scratch because of weird library/database problems.Basically, i suggest not to use collections to replicate the physical folder structure, but rather to collect images independent of physical storage to serve a particular purpose. The folder structure is already available as a selection means.
Collections are used to keep a user defined selection of images as a persistent collection, that can be easily accessed.
Smart collections are based on criteria that are understood by the application and automatically kept up to date, again as a persistent collection for easy access. If this is based on a simple criterium, this can also, and perhaps even easier, done by use of keywords. If however it is a set of criteria with AND, OR combinations, or includes any other metadata field, the smart collection is the better way to do it. So keywords and collections in Lightroom are complementary to eachother.
I use (smart)collections extensively, check my website www.fromklicktokick.com where i have published a paper and an essay on the use of (smart)collections to add controls to the workflow.

Microsoft Visual Basic 2010 Express.
I am new to Visual Basic programing and i am trying to understand the relationships between Datasets, database, table Adaptors. I have to following code that is is giving me the following error" Unable to load, Update requires a valid DeleteCommand
when passed DataRow collection with deleted rows".
I can track the error and its located in "OffsetTableTableAdapter.Update(MaterionOffsetDataSet.OffsetTable)" code. What am i missing?
It seems that i can delete the data on the DataGridView Table and it only displays the correct data. but my database is not updating, even though the data grid displays differently.I can determine this because, when i save the offset database, i have all
the previous uploads and all the rows that i wanted to delete are still there.
My final goal is to be able to import offset data from a CSV file, save this data on the pc, send a copy of this data to a NuermicUpDown so the customer can modify certain numbers. From here they download all the date to a controller. IF the customer
needs to modify the imported data, they can go to a tab with a data grid view and modify the table. They will also have to option to save the modified data into a csv file.
Im not sure if i am making this overcomplicated or if there is a easier way to program this.
CODE:
Private Function LoadOffSetData()
Dim LoadOffsetDialog As New OpenFileDialog 'create a new open file dialog and setup its parameters
LoadOffsetDialog.DefaultExt = "csv"
LoadOffsetDialog.Filter = "csv|*.csv"
LoadOffsetDialog.Title = "Load Offset Data"
LoadOffsetDialog.FileName = "RollCoaterOffset.csv"
If LoadOffsetDialog.ShowDialog() = Windows.Forms.DialogResult.OK Then 'show the dialog and if the result is ok then
Try
Dim myStream As New System.IO.StreamReader(LoadOffsetDialog.OpenFile) 'try to open the file with a stream reader
If (myStream IsNot Nothing) Then 'if the file is valid
For Each oldRow As MaterionOffsetDataSet.OffsetTableRow In MaterionOffsetDataSet.OffsetTable.Rows
oldRow.Delete()
'delete all of the existing rows
Next
'OffsetTableTableAdapter.Update(MaterionOffsetDataSet.OffsetTable)
Dim rowvalue As String
Dim cellvalue(25) As String
'Reading CSV file content
While myStream.Peek() <> -1
Dim NRow As MaterionOffsetDataSet.OffsetTableRow
rowvalue = myStream.ReadLine()
cellvalue = rowvalue.Split(","c) 'check what is ur separator
NRow = MaterionOffsetDataSet.OffsetTable.Rows.Add(cellvalue)
Me.OffsetTableTableAdapter.Update(NRow)
End While
Me.OffsetTableTableAdapter.Update(MaterionOffsetDataSet.OffsetTable)
MainOffset.Value = OffsetTableTableAdapter.MainOffsetValue 'saves all the table offsets
to the offset numericUpDown registers in the main window
StationOffset01.Value = OffsetTableTableAdapter.Station01Value
StationOffset02.Value = OffsetTableTableAdapter.Station02Value
myStream.Close() 'close the stream
Return True
Else 'if we were not able to open the file then
MsgBox("Unable to load, check file name and location") 'let the operator know that the file wasn't able to open
Return False
End If
Catch ex As Exception
MsgBox("Unable to load, " + ex.Message)
Return False
End Try
Else
Return False
End If
End FunctionHello SaulMTZ,
>>I can track the error and its located in "OffsetTableTableAdapter.Update(MaterionOffsetDataSet.OffsetTable)" code. What am i missing?
This error usually shows that you do not initialize the
DeleteCommand object, you could check this
article to see if you get a workaround.
>> Im not sure if i am making this overcomplicated or if there is a easier way to program this.
If you are working CSV file, you could use OleDB to read it which would treat the CSV file as a Table:
http://www.codeproject.com/Articles/27802/Using-OleDb-to-Import-Text-Files-tab-CSV-custom
which seems to be easier (in my opinion).

Applet failed to load when visited using HTTPs protocol with Java 7
We have a java applet on our website which worked for ages. Then Java 7 came out, people installed it. When people with Java 7 visiting our website using HTTPS, the applet failed to load (ClassNotFoundException). The same site and the same applet, when visit using regular HTTP, it works fine.
People with previous version of Java (1.6.x) can see the applet using either HTTP or HTTPs with no problem.
Anything we can do on our side to resolve this problem for people with Java 7 and like to stay with HTTPS?
Googled and didn't see any relevant result. Any pointer would be much appreciated.Thanks for the quick response.
Not much on the stack trace, did a tread dump below.
It is an application requires login, please sent and email to [email protected] and I will sent you the url and login info by email.

I have followed the "usual" way to build a pooled VDI desktop using Win7 or Win8 with success, but it fails when I use an image of Win Server 2012 as VM instead.
Am I overlooking something? Should I need to prepare the image in a different way? (Sysprep differently?)
ThanksHi,
Thank you for your posting in Windows Server Forum.
Can you specify the error which you are facing during VDI setup for server 2012?
I might think that you need to check the memory setting for server 2012, as might happens that due to less memory you can’t setup the VDI setup properly.
Memory: If the Master VM is configured with static memory, it must have at least 1024 MB as startup RAM. If the Master VM is configured with dynamic memory, the maximum RAM must be at least 1024 MB.
Please check beneath article for information.

Single Image Management for Virtual Desktop Collections in Windows Server 2012
Hope it helps!
Thanks.

Using collections and experiencing slow response
I am experiencing slow response when using htmldb_collection. I was hoping someone might point me in another direction or point to where the delay may be occurring.
First a synopsis of what I am using these collections for. The main collections are used in order to enable the users to work with multiple rows of data (each agreement may have multiple inbound and outbound tiered rates). These collections, OBTCOLLECTION and IBTCOLLECTION, seem to be fine. The problem arises from the next set of collections.
OBTCOLLECTION and IBTCOLLECTION each contain a field for city, product, dial code group and period. Each of these fields contains a semi-colon delimited string. When the user chooses to view either the outbound tiers (OBTCOLLECTION) or the inbound tiers (IBTCOLLECTION), I generate four collections based on these four fields, parsing the delimited strings, for each tier (record in the OBT or IBT collection). Those collections are used as the bases for multiple select shuttles when the user edits an individual tier.
Here is the collection code for what I am doing.
When the user chooses an agreement to work with, by clicking on an edit link, they are sent to page 17 (as you see referenced in the code). That page has the on-demand process below triggered on load, after footer.
-- This process Loads the collections used
-- for the Inbound and Outbound tier details
-- OBTCOLLECTION
-- IBTCOLLECTION
-- It is an on-demand process called on load (after footer) of page 17 --
-- OUTBOUND TIER COLLECTION --
if htmldb_collection.collection_exists( 'OBTCOLLECTION') = TRUE then
htmldb_collection.delete_collection(p_collection_name => 'OBTCOLLECTION' );
end if;
htmldb_collection.create_collection_from_query(
p_collection_name => 'OBTCOLLECTION',
p_query => 'select ID, AGREEMENT_ID, FIXED_MOBILE_ALL,
OF_TYPE,TIER, START_MIN, END_MIN,
REVERT_TO, RATE,CURRENCY,
PENALTY_RATE, PENALTY_CURR,
PRODUCT,CITY, DIAL_CODE_GROUP, PERIOD,
to_char(START_DATE,''MM/DD/YYYY''),
to_char(END_DATE,''MM/DD/YYYY''),
MONTHLY,EXCLUDED,
''O'' original_flag
from outbound_tiers
where agreement_id = '''||:P17_ID ||'''
order by FIXED_MOBILE_ALL, ID',
p_generate_md5 => 'YES');
-- INBOUND TIER COLLECTION --
if htmldb_collection.collection_exists( 'IBTCOLLECTION') = TRUE then
htmldb_collection.delete_collection(p_collection_name => 'IBTCOLLECTION' );
end if;
htmldb_collection.create_collection_from_query(
p_collection_name => 'IBTCOLLECTION',
p_query => 'select ID, AGREEMENT_ID, FIXED_MOBILE_ALL,
OF_TYPE,TIER, START_MIN, END_MIN,

from inbound_tiers
where agreement_id = '''||:P17_ID ||'''
order by FIXED_MOBILE_ALL, ID',
p_generate_md5 => 'YES');
commit;The tables each of these collections is created from are each about 2000 rows.
This part is working well enough.
Next, when the user chooses to view the tier information (either inbound or Outbound) they navigate to either of two pages that have the on-demand process below triggered on load, after header.

END;Creating these collections from the initial collection is taking way too long. The page is rendered after about 22 seconds (when tier collection has 2 rows) and 10 minutes worst case (when the tier collection has 56 rows).
Thank you in advance for any advice you may have.Try to instrument/profile your code by putting timing statements after each operation. This way you can tell which parts are taking the most time and address them.

When to use the new file based content repository
In Service Pack 4 there's a new implementation of the CMSPI interfaces which is configured by using the following implementation class:
com.bea.content.spi.internal.FileSystemRepositoryImpl
When should one use this new file based repository versus the existing one (configured by using the following class: com.bea.content.spi.internal.RepositoryImpl).
I've read the edocs, but it doesn't state when to use this new one compared to the previous implementation.
We consider using a third party content repository, but for the time being we will use the content repository provided by BEA.
Trond Andersen, Invenia AS, +4798290811use the new keyword when you don't have an instance of that object in memory that you want to use. For example...
if you have an object already in memory that is holding a property with a "CamelQuery" object, then you can say
var query = myobject.Query;
however, if you have to write the query, or instantiate the object from nothing, then you need to use the "new" keyword. A good example is SPSite object...
if you can get a new SPSite object by either "newing one up and passing the URL" or getting the farm and getting a site from that object.
using(SPSite site = new SPSite("url to my site"))
now I can use site.
//or
SPSite = myWebApp.Sites[0];
// this gives you site at index 0 of current webApp
most of the time in SharePOint you will be using the "new" keyword to open site collections, and then getting your subsites from there. BE CAREFUL using the "new" keyword. If you "new" up an object that is iDisposable... you
MUST dispose of that, but if you use that same object but it comes from the "current context", you mustn't dispose of it.
//dispose of this by using statement
using(SPSite site = new SPSite(<url>))
//do stuff
//after this bracket it is disposed.
//do not dispose of this:
SPSite mysite = SPContext.Current.Site;
//unpredictable behavior can occur because you will still need references to your current site. -
How can I work with lightroom when I use two computers ?
I am new to Lightroom and work with a laptop at home and a PC at work. Before I started to use LR3 I simply duplicated my pic files onto both machines, edited on whichever machine I wanted and then synchronised the folders. This system provided me with a working copy at either home or work and also a backup copy on the other machine.
I would like to operate the same system with LR3 but am unable to figure it out due to the automatic filing system used by the programmme to seperate the raw files and the instructions for those files.
Can anyone provide me with simple step by step instructions on how to transfer the files/instructions by using a flash drive and "Copy and replace"system
as I am totally confused by the grammar, syntax, and terminology used by Adobe.Hi Geoffbubbles,
if you see only 1 photo you did export only 1 photo in the catalog.
Make sure you select all (e.g. <ctrl> A or remove the tick from "export selected photos only" in the dialog box of export-as-catalog =>will pick the total folder).
What Dorin mentions are catalogs as transportation vehicles between the two LR computer catalogs.
Let's assume you start on your home-comp and transfer to the work-comp.
When you EXPORT you give a name "home-to-work" for the transport catalog. You decide if you include the pictures by ticking "exclude negative files".
You would do so only for the first time, when your work-comp would not yet have them.
These are the original files which would never be touched, but which LR needs to have available to do develop work (i.e. to write develop instructions into its database). [Or maybe only you need them in order to have LR display the effects of what you are doing, if your slider settings achieve your desired result.]
When you transfer your new settings from the work-comp to the home-comp which has the original files already you only need to transfer the DB-records for the files, i.e. the catalog parts. Then it is sufficient to export-as-catalog (name it "work-to-home") without the tick for the negative files. Which will obviously save a lot of data to transfer.
As would leaving off the tick for "include available previews", but then your receiving computer would have to render the previews itself - your choice where you spend the effort.
Depending on your ticks checked in export dialog the data on the transfer stick will show different folders:
1 wrapping folder with the name you specified as transportation catalog name (in the example above "home-to-work")
therein the catalog file *.lrcat (home-to-work.lrcat)
if "include negative files" ticked: as many subfolders as the original folder structure/names of the pictures in it had on the sending machine
if "include available previews" ticked: an *Previews.lrdata-folder ("home-to-work Previews.lrdata") with lots of subfolders labelled 0...F
On the receiving computer, when you IMPORT FROM CATALOG, you only select the *.lrcat-file.
In the dialog box you decide if you import the negative files (prereq you had included them) or if you just add them without moving (why not leave them on the stick i.o. actually copying over to the work-comp?). If there are no new photos, but just new settings, you can either overwrite your old settings (which is probably your intention) or tick "preserve old settings as virtual copies".
When you use Dorins smart collection "Touched today" the virtual copies should not show up upon re-export on the way "work-to-home", provided you have further tweaked the master versions only. Or they do because in the end you liked them better and continued tweaking on them.
Note if you do not include previews: you might need to tell LR on the receiving comp to rerender the previews if it contains the photos and earlier previews already - I am not sure, if LR starts off on its own to rerender them. -
Hi ,
To improve the performance of the insert statement i was adviced to use the collections.

hi all ,
i want to add net value of all the line items which are in the same group
am using collect but am unable to do that.
plz suggest me what to do?

vbeln like vbap-vbeln, " Sales document
grkor like vbap-grkor, " Delivery group
netwr like vbap-netwr, "net value
posnr like vbap-posnr, " Sales document item
End OF del_grp_data.
SELECT vbeln grkor pstyv netwr
posnr
FROM vbap
INTO corresponding fields of TABLE del_grp_data
FOR ALL ENTRIES IN orders_vbeln
WHERE vbeln eq orders_vbeln-vbeln.
loop at del_grp_data.
collect ord_grp_data .
endloop.

COLLECT [wa INTO] itab.
Addition:
... SORTED BY f
Cannot Use Short Forms in Line Operations.
Effect
COLLECT allows you to create unique or summarized datasets. The system first tries to find a table entry corresponding to the table key. (See also Defining Keys for Internal Tables). The key values are taken either from the header line of the internal table itab, or from the explicitly-specified work area wa. The line type of itab must be flat - that is, it cannot itself contain any internal tables. All the components that do not belong to the key must be numeric types ( ABAP Numeric Types).
If the system finds an entry, the numeric fields that are not part of the table key (see ABAPNumeric Types) are added to the sum total of the existing entries. If it does not find an entry, the system creates a new entry instead.
The way in which the system finds the entries depends on the type of the internal table:
STANDARD TABLE:
The system creates a temporary hash administration for the table to find the entries. This means that the runtime required to find them does not depend on the number of table entries. The administration is temporary, since it is invalidated by operations like DELETE, INSERT, MODIFY, SORT, ...). A subsequent COLLECT is then no longer independent of the table size, because the system has to use a linear search to find entries. For this reason, you should only use COLLECT to fill standard tables. U
SORTED TABLE:
The system uses a binary search to find the entries. There is a logarithmic relationship between the number of table entries and the search time.
HASHED TABLE:
The system uses the internal hash administration of the table to find records. Since (unlike standard tables), this remains intact even after table modification operations, the search time is always dependent on the number of table entries.
For standard tables and SORTED TABLEs, the system field SY-TABIX contains the number of the existing or newly-added table entry after the APPEND. With HASHED TABLEs, SY-TABIX is set to 0.
Notes
COLLECT allows you to create a unique or summarized dataset, and you should only use it when this is necessary. If neither of these characteristics are required, or where the nature of the table in the application means that it is impossible for duplicate entries to occur, you should use INSERT [wa INTO] TABLE itab instead of COLLECT. If you do need the table to be unique or summarized, COLLECT is the most efficient way to achieve it.
If you use COLLECT with a work area, the work area must be compatible with the line type of the internal table.
If you edit a standard table using COLLECT, you should only use the COLLECT or MODIFY ... TRANSPORTING f1 f2 ... statements (where none of f1, f2, ... may be in the key) enthalten sein). Only then can you be sure that:
-The internal table actually is unique or summarized
-COLLECT runs efficiently. The check whether the dataset
already contains an entry with the same key has a constant
search time (hash procedure).
If you use any other table modification statements, the check for entries in the dataset with the same key can only run using a linear search (and will accordingly take longer). You can use the function module ABL_TABLE_HASH_STATE to test whether the COLLECT has a constant or linear search time for a given standard table.
Example
Summarized sales figures by company:
TYPES: BEGIN OF COMPANY,
NAME(20) TYPE C,
SALES TYPE I,
END OF COMPANY.
DATA: COMP TYPE COMPANY,
COMPTAB TYPE HASHED TABLE OF COMPANY
WITH UNIQUE KEY NAME.
COMP-NAME = 'Duck'. COMP-SALES = 10. COLLECT COMP INTO COMPTAB.
COMP-NAME = 'Tiger'. COMP-SALES = 20. COLLECT COMP INTO COMPTAB.
COMP-NAME = 'Duck'. COMP-SALES = 30. COLLECT COMP INTO COMPTAB.
Table COMPTAB now has the following contents:
NAME | SALES
Duck | 40
Tiger | 20
Addition
... SORTED BY f
Effect
COLLECT ... SORTED BY f is obsolete, and should no longer be used. It only applies to standard tables, and has the same function as APPEND ... SORTED BY f, which you should use instead. (See also Obsolete Language Elements).
Note
Performance:
Avoid unnecessary assignments to the header line when using internal tables with a header line. Whenever possible, use statements that have an explicit work area.
For example, " APPEND wa TO itab." is approximately twice as fast as " itab = wa. APPEND itab.". The same applies to COLLECT and INSERT.
The runtime of a COLLECT increases with the width of the table key and the number of numeric fields whose contents are summated.
Note
Non-Catchable Exceptions:
COLLECT_OVERFLOW: Overflow in an integer field during addition
COLLECT_OVERFLOW_TYPE_P: Overflow in a type P field during addition.
TABLE_COLLECT_CHAR_IN_FUNCTION: COLLECT on a non-numeric field.

WHen I use lightroom mobile I have 57 photos on my iphone . I transfer them to my ipad and then I try to put them in Lightroom mobile from my ipad camera roll and only 32 show and transfer
Same problem here, and with even fewer photos. There should be 14 photos (per the LR collection info), but when I view on my iPhone (5s), only 11 appear. They do all appear on my computer. I've tried the following to make it work on my phone:
Creating a new collection and importing there. It says one photo is in the collection, but none actually appear.
Completely shutting down and rebooting the iPhone.
Deleting and re-downloaded the app.
None of these have worked.
