Generating names for instanses of classes dynamically pls help????

Hi this is what i am trying to do. I have two classes. 1)DragDrop and 2) Create. In the create class I want to declare an instance of DragDrop and call a method from the DragDrop class. The method i want to call is to draw an object to the screen. So if i wanted to draw one object the call would be:
DragDrop d = d.add(object)
I do not know how many objects need to be drawn till runtime, and I also need to be able to know the variable name assigned to the instance of the class, so for 100 objects i will need to know 100 variable names, this is so that each object can be manipulated and i need the variable name to do this. What i want to know is how can i assign different variable names depending on the number of objects that need to be drawn, i have considered using hashmaps but still don't see how it would be possible, any help would be much appreciated. Thanks.

It's not possible. A Map is the closest you can get.

How to change the package name for a msg class

Can anybody tell me how to change the package name for a message class.
and how will it effect in the rerport?
thanks in advance
kp

>>and how will it effect in the report?
You wouldn't see any direct effect on the Report.. But if you transport the report to QA & leave the Message class in Dev, it might result in syntax issues & you will not be able to execute the report. Just ensure that both of them get transported to QA & you will be fine.

Did you change your card details on your account a number of times when trying to purchase the item, and five of them are temporary store holding charges : http://support.apple.com/kb/HT3702 ?
If they are all 'proper' charges then try the 'report a problem' link to contact iTunes Support : http://reportaproblem.apple.com

Query: Missing tablename in generated SQL for vertical mapped classes

Hi,
I am playing with Kodo 3.1.4 / Postgres 7.4 and could not find any
solution for this problem:
I have one class calles "Clipfragment" which represents video clips and
has a long - field named "lengthInMinutes". It extends a baseclass
called "Categorizablefragment", which has a field "id" and some others.
I use vertical mapping, thus having one table per class. The identity
type is 'application'. The table for the class "Categorizablefragment"
contains fields for jdoclass and jdoversion and IMHO correct entries.
Everything works really fine except for Querys against subclass fields
with aggregate functions. E.g. counting all clips works:
KodoQuery q = (KodoQuery) getJdoPm().newQuery(ClipFragment.class);
q.setResult ("count(id)");
Number count = (Number) q.execute ();
But: Querying for the sum of the field 'lengthInMinutes' fails:
KodoQuery q = (KodoQuery) getJdoPm().newQuery(ClipFragment.class);
q.setResult ("sum(lengthInMinutes)");
Number count = (Number) q.execute ();
The exception is:
kodo.util.UserException: com.solarmetric.jdbc.ReportingSQLException:
ERROR: syntax error at or near "WHERE"

I tried both 'base-tables' and 'per-subclass' for the property

Any ideas?

Plese help me..
thaks in advance..
pls help me..</b>

Hello,
Define your select-option in TVARV (assume Z_THISWEEK). And use a program like:
DATA:
zlv_week TYPE KWEEK.
call function 'DATE_GET_WEEK'
   exporting date = syst-datum
   importing week = zlv_week.
SELECT SINGLE *
      FROM tvarvc
     WHERE name = 'Z_THISWEEK'
       AND type = 'S'
       AND numb = '0000'.
tvarvc-low = zlv_week.
IF syst-subrc <> 0.
    tvarvc-name     = 'Z_THISWEEK'.
    tvarvc-type     = 'S'.
    tvarvc-opti     = 'EQ'.
    tvarvc-sign     = 'I'.
    tvarvc-numb     = '0000'.
    insert tvarvc.
ELSE.
update tvarc.
ENDIF.

How is the design for this complex requirement ? pls help..

Hi All,
We have a Discount scheme that can be given for all possible
combination of all customer, area and product hierarchy (attached below).
for example :
Promotion No.001 =>for sales on : CustomerGroup 'A', Area 'B', and
ProductBrand 'C' will get discount 2 %
Promotion No.002 =>for sales on : AllCustomer, District 'D', and
Product 'E' will get discount 2.5 %
Promotion No.003 =>for sales on : CustomerType 'F', AllArea, and
ProductGroup 'G' will get discount 3 %
... and any possible combination.
And it is possible for an Order / Invoice to get discount from two or
more different promotion.
e.g: Order 001, get 2 % from Promotion No.001 and 3 % from Promotion
No.003, so totally it gets 5% discount.
(1) Customer Hierarchy
AllCustomer
CustomerGroup
CustomerType
Customer
(2) Area Hierarchy
AllArea
Region
District
Area
(3) Product Hierarchy
AllProduct
ProductGroup
ProductBrand
Product
Our Orders Data has following attributes :
OrderNo.
Customer
Area
Product
Gross
Discount
Additional info :
- Oracle version : 10g
- If multiple discounts are applied, e.g: two discount, 10% each, then
the total discount is 20%, if gross = 100, then netto is 100 * 80% =
80.
The design that comes to my mind is like below, please give me
correcttion and recommendation :
The Promotions is defined in master-detail :
- one master table
- three detail tables (one for each possible hierarchy)
- one additional Tabel to store detail of discount an Order get,
because it can get 2 or more discount.
PromoHeader :
- PromoNumber
- Description
- StartDate
PromoDetail1 :
- PromoNumber
- PType (ALL / CustomerGroup / CustomerType / Customer)
- PCode (ALL / 'xxxx' )
( note : 'xxxx' can be Customer Group Code, Customer Type Code or
Customer Code )
PromoDetail2 :
- PromoNumber
- PType (ALL / Region / District / Area)
- PCode (ALL / 'xxxx' )
( note : 'xxxx' can be Region Code, District Code or Area Code )
PromoDetail3 :
- PromoNumber
- PType (ALL / ProductGroup / ProductBrand / Product)
- PCode (ALL / 'xxxx' )
( note : 'xxxx' can be ProductGroup Code, ProductBrand Code, Product
Code )
PromoByOrder
- OrderNumber
- PromoNumber
- PType
- PCode
- Discount (%)
(if an Order get two discount, there will be two records on this table
for thet order)
The question is :
1) is this a 'good enough' design ?
2) if I do go with this design, how is the efficient query / plsql to
calculate the discounts for an Order.
Pls help..
Thank you very much,
xtanto

How was your wife using the Find My iPhone app from a Samsung phone? But, that question aside, your wife should educate herself on how GPS works, especially on a cell phone. GPS signals can be interfered with by trees, buildings, clouds. Off by several miles would be unusual, though.
If your wife is tracking your cell phone and not believing what you tell her, you may want to consider counseling as there are some very serious issues that go way beyond the technology.
Best of luck.

Iphone 6 screen broken. local authorized service center cannot be reached despite arranging for "schedule a call" session. pls help

iphone 6 screen broken. local authorized service center cannot be reached despite arranging for "schedule a call" session. pls help

They do not know where your phone is yet because it has not had enough time to go through the process yet. I also started to worry when two weeks had passed and my iPhone 5S was still showing not received on the status website. That's when I joined this forum to see if anyone else was having the same problem. What I found out was that some people had been given reduced value for their trade in, but I also found posts from people like myself that were worried that their phone was lost and then came back and posted a week or two later that they had received their gift card.
I decided to chill and give it some time and about a week later my gift card arrived. If it had been for less than the promised amount I would no doubt still be upset and posting about it like the many posts I still see on here on a regular basis.
This is no doubt a popular program for Verizon. I would imagine there have been thousands of phones traded in. There are going to be at least some screw ups in the process. There is no point in getting ahead of yourself and assuming your case will be one of the screw ups unless it already is. Verizon has been consistently posting that it could take 4-6 weeks for processing. You will at some point likely hear the status on your traded-in phone. Patience would not hurt in this case.

I am not able to download the .dmg file for my mac book pro. pls help.

i am using a mac book pro - mac os x 10.6.4 on a 2.33 ghz intel core duo processor. i am unable to fully download the .dmg file to install firefox. the file begins download within the browser itself and the browser window screen goes black after a while and stays there. no .dmg file to be seen. pls help.

The latest version iOS 6 does not run on the original iPad. That's why you cannot download it.

System generated name for PSA

Hi friends,
Could anyone tell me how to see the syatem generated table name of PSA and where to see.Thanks in advance.
Venkat

Hi Kiran,
You can also find the name of the PSA table in the following way:
In SE16 click F4 and then Information System.In the Short Description field put in the name of the InfoSource within *, like 0MATERIAL_ATTR and click the check mark. You will get the /BIC/ table (PSA table) that you are looking for.
Hope this helps...

Role Maintenance - Automatically generated names for authorization objects

Hello NG,
I've got a question concerning the mentioned subject.
Currently I am maintaining the roles/authorizations of a customers system (Rel. 3.0) which has moved to Rel. 7.0.
When I add an authorization object to a role, the technical name is generated automatically. How can I set up the naming conventions for the authorization objects?
Thank you very much.
Regards ..

Hi SUNIL L,
I refered to 3.0 but I think that the release version has no relevance for my problem. I think I should try to explain my problem once more:
When I add an authorization object to a role, a technical name is generated automatically and assigned to it. Is it possible to set any naming conventions for this?

Session Time Out For UNLOGGED USER During Search -pls help

Hi,
The problem lies in searchresultscontroller.java/searchcontroller.java file under search/web/handler of an application that supports educational note sharing.
The problem is that -
When I search with query strings in different fields(as you will find in the above mentioned java files)..the keywords in resourcedto and get some files as search results.
Then I click on one of the file from within the search result and visit the file.
Here if I m logged in as an user, and the session time out is set to 1 minute in the web.xml file of the web folder not the admin folder then when I hit the BACK TO SEARCH button it easily goes back to the previous search result page along with the queries string that I had input previously.
The problem is that when I m NOT LOGGED in as an user, and I've performed a search with queries and other dropdowns in the search panel, I get the search result page, I visit the file by clicking on one of them but when I hit the BACK TO SEARCH button I don't see the previous search result page from where I had navigated to view the file.
Please suggest on what changes shall I make in the code so that even if I m not logged in as an user, I get back to the search result page on hitting the BACK TO SEARCH button from the file view page.Sir I m herein pasting the code of the searchresultscontroller.java file, but please feel free to ask for anyother file whose code you might want to see.

hi,
You can assign the relevant roles to the user you have basing on the requirements. It is not necessary that each and every user should by default have roles except for service and system users. So no tension..
