Sorting HashSet without using the tree set?

Hi,
I need to sort the hash set by using the comparator, if i use the comparator in tree set to sort my hash set then it will check the uniqueness condition also using the same comparator. So i will lose some elements in the set.
So i want to sort no need to check the uniqueness.
Is there any API is available in java to achieve this. Like sorting the list we use the Collections.sort method. Like this any API is available to sort the hash set or any other ways can we achieve this (without using tree set sorting the hash set.)?
Thanks in advance.

Thanks for your reply.
I had done those things earlier like you said, the application i am using is frequently running out of memory i don't want to use more objects. If i am converting to list then it will create the another object to hold the elements of the hash set. Because of this only i am seeking for any other API is available.Perhaps you should try to find the source of your memory problems in stead of doing your very best to not have to do that; the way you're trying to "solve" things now is only going to lead to epic failure, I mean you're now as far gone as trying to not create objects in an object oriented language.
Try a profiler.

How do I set up my new Macbook Pro without using the annoying Voiceover?

How do I set up my new MacBook Pro without using the annoying Voiceover? I cannot get it to work right; it seems to get stuck and repeats the same thing over and over. It is driving me nuts! Is there a way to begin the setup process without using the Voiceover system? I am a new convert from a PC and I thought a Mac was supposed to be "intuitive!"
Any help is appreciated.
Thanks.
Pamela

There is no good reason to register your Mac anyway.
You can opt out of the setup process and registration by pressing Command (Apple key) and the "Q" key.
The registration process requires you to divulge a lot of unnecessary information.

How to migrate Master Data (Rule set etc.) from GRC 5.3 to 10.1 without using the "Migration Tool"

Greetings,
We are currently on GRC 5.3 SP 18 (Java ONLY) and migrating to GRC 10.1. I referred the Migration Guide which outlines that GRC 5.3 needs to be upgraded to SP 20 as pre-requisite for using the "Migration Tool" . Our BASIS team is reluctant to perform this upgrade from SP 18 to SP 20.
Having said thus, I'm exploring options of migrating data from 5.3 to 10.1 without using the "Migration Tool:.
Rule set Migration:
I'm in the process of preparing the 9 different files (listed below) and later utilize the "Upload Rule" option for migrating the Rule set data from 5.3 to 10.1.
While I'm able to gather data for most of the files I'm not sure how can I obtain the data pertaining to the two files (Function Actions and Function Permissions) underlined and highlighted in Red below.
1. Business Process
2. Function
3. Function Business Process
4. Function Actions
5 .Function Permissions
6. Rule Set
7. Risk
8. Risk Description
9. Risk Rule Set Relationship
10. Risk Owner Relationship
Can someone please enlighten me and share their experience with regards to this exercise. Really appreciate your help !
- Janantik.

I have done this successfully before. Because you are having issues, I would NOT recommend using the migration tool to move the ruleset. Instead:
1. Download the ruleset files from 5.3
2. The 5.3 tcode-permission file, which defines which tcode permissions from SU24 need to be checked during risk analysis, needs to be split into the two files you mention above in red.
FUNCTION_ACTION : this file represents S_TCODE objects and TCD fields mapped to each function (Function to Tcode relationship). In the 5.3 file, you will filter on object S_TCODE and field TCD, and you will get a complete list that now represents "FUNCTION_ACTION". BUT instead of having all the jumbled permission info, you will just have 3 columns: Function - Tcode - Status.
3. The remaining permissions that are left over, after taking out the S_TCODE -TCD items, represent the "FUNCTION_PERMISSION" file in GRC 10.
4. Manually create the excel spreadsheets for each file.
5. Copy and past each sheet to a unique .txt file.
6. Upload the ruleset manually through SPRO-->GRC-->Access Control-->Access Risk Analysis-->SoD Rules-->Upload SoD Rules.
7. Select each file and then upload to the correct Logical Group.
This is a huge pain, but it works. Let me know how this goes and if you need any assistance.

Manually set up the essbase 11 client (without using the fusion installer)

Hi All,
is it possible to install the Essbase 11 client without using the Fusion Installer?
I tryed to copy the "bin" and "locale" directory from an exisiting installation and set up the ARBORPATH environment variable - without success.
Did I miss anything? Maybe some Registry entries? Or isn't it possible to set up the essbase client manually?
Every answer would be appreciated.
Cheers,
Martin

Hi John,
thanks for the hint that the addin is also available for any version.
I have an application which uses the C-API (essapinu.dll, essotlnu.dll, ...) and I want to test it with diffrent Essbase Client Versions against diffrent Essbase Servers.
These are the (client) versions which I want to test:
EssbaseRtc11110WindowsFiles
EssbaseRtc11111WindowsFiles
EssbaseRtc11112WindowsFiles
EssbaseRtc11113WindowsFiles
EssbaseRtc9203WindowsFiles
EssbaseRtc9210WindowsFiles
EssbaseRtc9301WindowsFiles
EssbaseRtc9310WindowsFiles
I hoped it would be enough to replace some directorys on a machine instead of starting a lot of installers.
Cheers,
Martin

Is it possible to force 16/32-bit stack alignment without using the optimizer?

The compiler emits code targeted at the classic Pentium architecture for the -m32 memory model. I'm running into problems mixing Sun Studio compiled code with code built with other compilers because the other compiler builds under the assumption that the stack is 16-byte aligned.
The only way I've found to force Sun Studio to comply with that restriction is with -xarch={sse2a,sse3,...}, but this causes the code to pass through the optimizer. As noted in the documentation, if you want to avoid optimizations you must remove all flags that imply optimizations -- that is to say, there's no way to disable optimizations once enabled. This should not, however, be treated as an optimization because it's an ABI requirement.
I've scoured the documentation, spent many hours googling, digging through forums, and asking questions.
The best I've come up with is the -xarch option which is sub-optimal because it has side effects. I tried -xchip=pentium4 (this is what my other compilers have set as their default target), but the generated code doesn't force 16-byte stack alignment.
Is there a way to force the compiler to emit code conforming to a different ABI without using the optimizer?
-Brian

Thank you for your response.
I hope you won't mind my asking: do you have a way to prove that it's not possible to force 16-byte alignment without using the optimizer? I ask because your username / profile don't give the impression you work for Oracle, so while I think you're probably right it's at least possible that we're both mistaken. I haven't been able to find any documentation on either stack alignment or altering the targeted ABI short of using the -xarch flag, and even there the details are fairly sketchy.

I have a first generation iPad and got my husband the iPad 2 for xmas. is there a way to transfer his tiny tower game from my iPad to his without using the same iTunes account?

Apps are only tied to one account... You can set up two iTunes accounts on your computer, however, and let his iPad sync to his account. If he has never backed up his apps to a computer, however, he will have to redownload all the apps. Afterwards, he can backup to iCloud instead of your computer.

Transfer palm data from PC to Mac without using the M100 - only exporting the data and importing?

I had an old Palm M100 that I haven't used in a while but I love the palm desktop app - my PC currently runs 4.1.4
I have a mac powerbook and I loaded 4.2.1
When I export my calendar and address book data in the .aba and .dba format from my PC - the Mac palm desktop app doesn't seem to recognize those file formats.
Are those not standard formats between the two platforms? It also looks like the Mac desktop app doesn't even recognize importing data from another Palm format? It just shows the other program formats.
Also, when importing as CSV or tab-delimeted those are extremely messed up also.
Any "easy" way to get the data off of my PC and onto my Mac without using the Palm M100 itself?
Thanks,
Dave
Post relates to: Palm m100

The suggestion is not accurate, at least with respect to calendar information. I'm in nearly the same situation, and just tried it. (Saving .dba file out of Windows Palm Desktop 4.1.0, importing into Mac Palm Desktop 4.2.1revD.)
First, the Mac program will not recognize the .dba as an importable format if one selects All Readable Documents.
Second, if one selects All Documents instead, you get the following error message:
The file could not be imported.
In order to import data from Windows Palm Desktop software, export the file in one of these formats: comma (.csv) or tab (.tab) delimited, vCard, or vCal.
The problem with this is that Windows Palm Desktop 4.1.0 offers only two options for exporting Date Book information:
1) the whole datebook as a .dba file.
2) individual calendar items as a vCal.
So far as I can see, there's no way to Select All so as to export all as a vCal, and no pre-set option to do so.

How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file?

How can we send only one message to a WCF service at a time? How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file? Can we do it by Host throttling?

Hi Pawan,
You need to use WCF-Custom adapter and add the ServiceThrottlingBehavior service behavior to a WCF-Custom Locations.
ServiceThrottlingBehavior.MaxConcurrentCalls - Gets or sets a value that specifies the maximum number of messages actively processing across a ServiceHost. The MaxConcurrentCalls property specifies the maximum number of messages actively
processing across a ServiceHost object. Each channel can have one pending message that does not count against the value of MaxConcurrentCalls until WCF begins to process it.

Is it possible to create a DVD in iDVD without using the themes they provide?

Is it possible to create a DVD in iDVD without using the themes they provide?

Hi
No Menu DVD
from. Mishmunken
How to create a DVD in iDVD6 without menu (there are several options)
1. Easy. Drop your iMovie in the auto-play box in iDVD's Map View, then set your auto-play item (your movie) to loop continuously.
Disadvantage. The DVD plays until you hit stop on the remote
2. Still easy. If you don't want your (auto-play) movie to loop, you can create a black theme by replacing the background of a static theme with a black background and no content in the drop-zone (text needs to be black as well).
Disadvantage. The menu is still there and will play after the movie. You don't see it, but your disc keeps spinning in the player.
3. Still quite easy but takes more time. Export the iMovie to DV tape, and then re-import using One-Step DVD.
Disadvantage. One-Step DVD creation has been known to be not 100% reliable.
4. (My preferred method) Easy enough but needs 3rd party software. Toast lets you burn your iMovie to DVD without menu - just drag the iMovie project to the Toast Window and click burn.
Disadvantage. you'll need to spend some extra $$ for the software. In Toast, you just drop the iMovie project on the Window and click Burn.
5. The "hard way". Post-production with myDVDedit (free-ware)
Tools necessary. myDVDedit ( www.mydvdedit.com )
• create a disc image of your iDVD project, then double-click to mount it.
• Extract the VIDEO_TS and AUDIO_TS folders to a location of your choice. select the VIDEO_TS folder and hit Cmd + I to open the Inspector window
• Set permissions to "read & write" and include all enclosed items; Ignore the warning.
• Open the VIDEO_TS folder with myDVDedit. You'll find all items enclosed in your DVD in the left hand panel.
• Select the menu (usually named VTS Menu) and delete it
• Choose from the menu File > Test with DVD Player to see if your DVD behaves as planned. If it works save and close myDVDedit.
• Before burning the folders to Video DVD, set permissions back to "read only", then create a disc image burnable with Disc Utility from a VIDEO_TS folder using Laine D. Lee's DVD Imager.

Use HCM processes and Forms without using the Enterprise Portal

is it possible to leverage existing HR Admin Services (HCM processes and Forms) functionality without using the Enterprise Portal?
1) Create an Adobe form and Interface using SFP
2) Set up ISR and Form Scenario
3) Set up Forms configuration to use existing Backend and generic Services
4) Set up workflow to updated Backend using Services
is it possible to do the above steps and not use the Portal? If Yes, how do we present the forms to the Manager, and provide different buttons that appears on the Portal by default?
Any ideas will be greatly appreciated.
Thanks,
Saurabh

Hi Saurabh,
your assumptions and findings (items can not be started from the backend workflow inbox etc.) are correct: These processes can not be started without the Portal and it is not intended to do this.
The above mentioned backend report are only forseen for implementation and testing purposes and not for productive use.
In addition to the fact, that you already can't execute the work items a lot of other features of the framework (Process Browser etc.) are only available through the Portal.

How to dismiss the spelling dialogue without using the mouse

I'd appreciate the right tip from anyone on how to dismiss the spelling dialogue in Mail without using the mouse. (I'm one of those guys who likes to use the keyboard as much as possible.) Here's the scenario:
I open a new message in Mail, type my text, press Cmd-Shift-D, then (because I have it set to check spelling when I "click send") up pops the spelling dialogue. That's fine as far as it goes, but many times I don't need any corrections because either I don't care or because the words are fine but just not recognized by Mail. So until now what I do is use the mouse to click on the far left one of the three round buttons in the upper left corner of the dialogue. I would like not to have to use the mouse, but pressing Esc or any other keys I try doesn't work to make it go away.
Your advice is welcome! Thanks.

Well, that window is actually a floating window, which means that it is meant to hang around. Notice that if you move Mail to the background (without hiding it), the spelling window hides itself, then shows itself again when you bring Mail back to the front. Floating windows are kind of in their own little world, meant to float above windows while not interfering with keystrokes sent to the frontmost window.
I would argue that it shouldn't be a floater, because nobody's going to want it around once they're done checking spelling. But that's kind of a matter of opinion, and obviously Mail's designers thought differently.
BTW, in the course of writing this, I discovered something -- if you click in the spelling window, so that you could type in the field there, Command-W will actually close the floater. But, of course, that still requires a click in the window with the mouse.

I want single update query without use the function.

I want to update sells_table selling_code field with max date product_code from product table.
In product table there is multiple product_code date wise.
I have been done it with below quey with the use of function but can we do it in only one update query
without use the function.
UPDATE sells_table
SET selling_code = MAXDATEPRODUCT(ctd_vpk_product_code)
WHERE NVL(update_product_flag,0) = 0 ;
CREATE OR REPLACE FUNCTION HVL.maxdateproduct (p_product IN VARCHAR2) RETURN NUMBER
IS
max_date_product VARCHAR2 (100);
BEGIN
BEGIN
SELECT NVL (TRIM (product_code), 0)
INTO max_date_product
FROM (SELECT product_code, xref_end_dt
FROM product
WHERE TO_NUMBER (p_product) = pr.item_id
ORDER BY xref_end_dt DESC)
WHERE ROWNUM = 1; -- It will return only one row - max date product code
EXCEPTION
WHEN OTHERS
THEN
RETURN 0;
END;
RETURN max_date_product;
END maxdateproduct;
Thanks in Advance.

Hi,
Something like this.
update setlls_table st
        set selling_code =(select nvl(trim(product_code)) from
                              (select product_code
                                      , rank() over (partition by item_id order by xref_end_dt DESC) rn
                                   from product
                               ) pr
                               where rn =1
                                     and pr.item_id = st.ctd_vpk_product_code
                           ) where NVL(update_product_flag,0) = 0 ;As such not tested due to lack of input sample.

Apple wireless keyboard won't let me delete without using the fn key.

My apple wireless keyboard won't let me delete in indesign without using the fn key. Is there a key command that I accidentally hit that causes that or something? I've never had this happen before. It isn't happening in any other program, just indesign cs4. Has anyone had this happen and how do I fix it?

I figured it out. My keyboard shortcut set in indesign was corrupt. I went back to the default set and created a new set and the delete key started working again.

Reporting Scores without Using the Built-in Quiz

Is it possible to set up a 'quiz' in captivate, without using the built-in quiz slides?
The quiz slides are quite restrictive and clumsy and I'd rather build them myself.
So, say if I had a slide that had a question on it and two answer buttons, 'true' and 'false'. Is it possible to use these buttons to execute an advanced action that assigned a score that could then be reported to the LMS?
Sorry if this is a silly question.
