General CROSSTAB question

Is it possible to create a crosstab report similar to:
FIELD A-designation(value 1,2 or 3)
FIELD B-year
C| data
D| data
whereby designation 1 will always have under it both columns with data for the requested year and columns with data for the requested year - 1, while designation with value 2 or 3 will have columns of data only for the requested year?
From my knowledge I can't see how it is possible to describe it in the layout; I am double-checking if there is a way around it.
Thank you .
Leah

Please disregard this question. I think that it will all work out.
Thanks to anyone who thought about my question.

General dreamwevaer question

hello dreamweavers.
im a newbie going to use dreamweaver from next week and beyond,so id like to ask the following:
should i design the website in photoshop and then import it into dreamwevaer,in order to code it?
is dreamwevaer flexible in design point of view,or is it mostly getting finished designs such as headers,footers,flash banners,
and then building up the site where things so and such.
thank you.

Hello Nancy.
seems like an informative website,i can see it is easy to understand the

A few general agent questions

We've been asked some general questions by our agents that I have been unable to find answers for, (although 4 and 5 are likely working as designed). We are running IPCC Express 7.0(1)SR05_Build504 and these are all phone agents. We do not run the agent desktop client. Any assistance in answering these questions would be greatly appreciated.
1. TransfertoVM softkey "grayed out" while on a CSQ call. Can it be enabled?
2. While logged in to CSQ, is there a way to start dialing prior to
lifting the receiver?
3. Is it possible to handle more than one CSQ call at a time, e.g. put a call on hold and answer
another CSQ call.
4. Upon selecting Agent Login (single-button login), can the agent automatically be put into Ready?
5. Upon Logout, can the phone be returned to the main screen, rather than getting the manual agent login screen?
Again, any assistance in answering these questions would be greatly appreciated.
Thanks,
Roger

Hi
1) Isn't that an IPMA softkey? Never tried it, but whilst it's not in the 'unsupported' list, I wouldn't expect using any IPMA features in conjunction with CAD would get you good results. If it doesn't cause you stuck/ghost calls, I would expect erroneous reports...
2) Being logged into a CSQ doesn't affect the way the phone works.
- You can dial the number then either lift the handset or hit dial (for speakerphone)
- You can press speakerphone or headset then dial
I guess what you are referring to is if you are using the IP Phone Agent in conjunction with a headset? If you are, then the IPPA usually obscures the 'new call' and 'end call' softkeys that you might use if you leave the headset button lit. I guess this isn't the case, as you refer to lifting the receiver? Unless you have motorized lifters.. If that's what you have, you can try getting users to either :
- Manage their onhook/offhook state using the headset key as if it was the speakerphone key (i.e. press it to hang up or pickup)
- Use a headset/phone combination that supports HHC
- Switch to CAD, or CAD-BE if you can't install PC software for some reason.
3) No. The system is designed specifically so that this should never happen.
4) No.
5) Again, no... you can't customize the BIPPA service... If you use CAD or CAD-BE this wouldn't be an issue.

Workflow and General Use Questions

Hello,
I'll apologize right off the bat for these novice question because I'm sure the information is probably somewhere in the forum, I just haven't been able to find it. I just purchased Aperture after completing the demo as my library is getting too large to manage using standard file folders. I'm now trying to figure out the best practices for workflow and general use before I invest some serious time into importing and keywording all my pictures.
1) Store files in the there current location, or in the Aperture Library? It seems to me that once they are moved to the Aperture library, you can only access them from within Aperture. I'm thinking I would be better off leaving them in their current location. For one, if I want to quickly grab a picture as an attachment to an email or something it seems easier to grab it from the standard folders. Second (and more important) I do not have room to keep all my pictures on my Macbook, thus most of them are stored on the Time Capsule.
So... Keeping photos in their current location appears to be the best choice for me even though it adds an additional step every time I bring in new photos from my camera. Does this sound right?
2) Is there a way to mark the photos that I have uploaded to my website (Smugmug)? Ideally, I would like to badge photos that have already been uploaded so I can quickly recognize them and ensure I'm not duplicating. I've considered using the rating, or keywords to indicate that a photo has been uploaded but both methods have disadvantages.
3) Any suggestions for general workflow and organization resources (tutorials, books, websites, etc.)? I've looked at the videos on Apple's site but they obviously didn't get that detailed.
Thanks for the help, sorry for the length.

I recommend to Manage by Reference with Master image files stored on external hard drives (note that Aperture defaults to a Managed-Library configuration rather than a Referenced-Masters Library). Especially important for iMacs and laptops with a single internal drive. The workflow as described below in an earlier post of mine uses a Referenced-Masters Library.
I feel pretty strongly that card-to-Aperture or camera-to-Aperture handling of original images puts originals at unnecessary risk. I suggest this workflow, first using the Finder (not Aperture) to copy images from CF card to computer hard drive:
• Remove the memory card from the camera and insert it into a memory card reader. Faster readers and faster cards are preferable.
• Finder-copy images from memory card to a labeled folder on the intended permanent Masters location hard drive.
• Eject memory card.
• Burn backup hard drive or DVD copies of the original images (optional strongly recommended recommended backup step).
• Eject backup hard drive(s) or DVDs.
• From within Aperture, import images from the hard drive folder into Aperture selecting "Store files in their current location." This is called "referenced images." During import is the best time to also add keywords, but that is another discussion.
• Review pix for completeness (e.g. a 500-pic shoot has 500 valid images showing in Aperture).
• Reformat memory card in camera, and archive originals off site on hard drives and/or on DVDs.
Note that the "eject" steps above are important in order to avoid mistakenly working on removable media/backups.
Also note with a Referenced-Masters Library that use of the "Vault" backup routine backs up the Library only, not the Masters. Masters should be separately backed up, IMO a good thing from a workflow and data security standpoint.
Max out RAM in your MB and keep the internal drive less than 70% full.
Good luck!

General BADi question:Call BADi in background job/batch input. Possible?

Hi out there,
i'm using thoe following BADi: /SAPSLL/CTRL_SD0C_R3 (Global Trade Service).
But also, this question is a general question.
If we are calling on screen the transaction VF01, the BADi is called correctly.
But unfortunately it seemes that the BADi is NOT called (im not really sure, cause i can't debug the background task) when we are calling a batch input sequence wth f.e. form bdc_transaction VF01 nothing happens.
Maybe BADi cannot be called in a background task? If it's possible, how could it be monitored. Thare isw no spool entry or anything like that!
Any answer can help.
Thank you in advance!
Regards,
Timo
Edited by: Timo Ehl on Apr 14, 2009 7:27 PM

Hi,
generally BADIs are called in background mode. You can use the following trick to debug your BADI. You just need to create an infinite loop in your BADI implementation. Something like this.
DATA: l_a TYPE c.
WHILE l_a IS INITIAL.
ENDWHILE.
Obviously when your BADI is called in background mode then program will get into infinite loop. You can easily connect and debug running programs from transaction SM50. You need to select your background process and go to Program/Session -> Program -> Debugging. You will jump directly into your BADI methos with infinite loop. Then you will just set value to l_a and you will start debugging your BADI. If you can not find any process then your BADI is not called in background mode.
Cheers

A general OOP question

Hi
I have a general OOP design question, and am wondering if someone could relate an answer to the following design?
I have a class called MediaFolderImport(); - it's designed to build a window with various editing tools in it.
Within it's constructor, I'm calling a bunch of functions to build the window...
   createTitle();
   createInstructions();
   createToolPanel();
   createDataGrid ();
   createOpen();
   createSave();
In my document class, I instantiate it...
public var File_Folder_Import:MediaFolderImport=new MediaFolderImport();
and then...
addChild(File_Folder_Import);
Voila! - the window appears. I WAS very proud of myself.
Now I want to access something inside the window. Specifically, there's a radio button that was created in createToolPanel(); - I want to update it to be selected or not selected when I receieve the user's preference from an xml settings file at start up (xml is loaded into the doc class).
General question:
What is the best practice, smart way to have designed this?
- call createToolPanel(); from the doc class instead of within MediaFolderImport();, and somehow (magically) have access to the radio button?
- leave the design as is, but add some sort of listener within MediaFolderImport that listens for changes to the xml in the doc class, and updates accordingly?
- do it the way I'm trying to, ie try to access the radio button directly from the doc class (which isn't working):
File_Folder_Import.myRadioButton.selected = true;
- a better way someone can briefly explain the concept of?
Another way to explain my design is...
- a bunch of different windows, each created by a different class
- xml file loads preferences, which need to be applied to different tools (radio buttons, check boxes, text fields etc) in the different windows
I read a lot of posts that talk about how public vars are mostly bad practice. So if you are making your class vars private, what is the best way to do the kind of inter-class communicating I'm talking about here?
I think someone throwing light on this will help me solidify my understanding of OOP.
Thank you for your time and help.

You're already very used to using properties for the built-in AS classes and that's the best practice means of configuring your class. It's a "state" that you want to simply expose. The get/set method moccamaximum mentioned is the ideal route.
The main reason you want to use get/set functions is validation. You want your class to act properly if you send an invalid value. Especially if anyone else besides yourself is going to use the class. Plan for the worst.
The general concept is, make a private variable for any 'state' you want to remember using an underscore in the variable name to easily identify it as a private var, then make get/set functions with the same name with any required validation without the underscore.
e.g.
package
     public class MyClass
          // property called 'mode' to track something with an int
           private var _mode:int = 0;
          public function MyClass() {} // empty constructor
          // get (type enforced)
          public function get mode():int { return mode; }
          // set, requiring a value
          public function set isChecked(modeVal:int):void
               // if no value is sent, ignore
               if (!modeVal) { return; }
               _mode = modeVal;
Your validation will go a long way to easily debugging your classes as they grow in size. Eventually they should throw exceptions and errors if they're not valid. Then you will be best practice. Do note that if your validation requires quite a bit of logic it's common to upgrade the property to a public method. get/set should be reserved for simple properties.

CrossTab Questions

I have a crosstab that looks something like this:
     Jan-08     Feb-08     Mar-08     Apr-08     May-08     Jun-08
Jan-08     A     B     C     D     E     F
Feb-08          G     H     I     J     K
Mar-08               L     M     N     O
Apr-08                    P     Q     R
May-08                         S     T
Jun-08                              U
There are two things I need to be able to do with this crosstab. First, I need to be able to paint the diagonals in different colors. For example, AGLPSU needs to be red, BHMQT needs to be blue, CINR needs to be green, DJO needs to be orange, EK needs to be brown and F needs to be yellow. There is no specific rule for these colors, just that each object within a diagonal needs to be the same color and each diagonal line needs to be a different color. In otherwords, the highlighting of each object is based on location and not value.
The second thing I need is to present a version of this crosstab as a % where AGLPSU are all 100%, B is the % if G, C and H are % of L, DIM are each the % of P, etc.
I can't figure out how to do either of these, or if it is possible to do either of these. If not, the client will be forced to export to Excel which frustrates the purpose of the report.
Fuskie
Who hopes someone has a positive answer...

Brilliant. I never would have thought of this. I had to put the column total formula into the Horizontal Alignment format property condition since the client wanted column totals suppressed and I extended the color selection to 13 (they run the report for 13 months), but it looks great. Now if only you could center a cross-tab horizontally on a page.
Here is a better discription of the second question. Take the following crosstab data:
     Jan-08     Feb-08     Mar-08     Apr-08     May-08     Jun-08
Jan-08     481     169     139     111     104     95
Feb-08          506     207     155     131     121
Mar-08               489     174     132     122
Apr-08                    388     175     138
May-08                         475     157
Jun-08                              426
I want the second crosstab to look like this:
     Jan-08     Feb-08     Mar-08     Apr-08     May-08     Jun-08
Jan-08     100%     33%     28%     29%     22%     22%
Feb-08          100%     42%     40%     28%     28%
Mar-08               100%     45%     28%     29%
Apr-08                    100%     37%     32%
May-08                         100%     37%
Jun-08                              100%
For February 08, 33% is 169/506. For March 08, 28% is 139/489 and 42% is 207/489, etc. Hope this is more clear.

Best Font for Subtitles? and other General Subtitling questions?

I've never had to use subtitles, until my current project, so I am looking for some general advice and suggestions.
I will be using PPCS3 (on XPpro) as the subtitles (as in the kind that translate a foreign language) will be permanent.
So here are my questions:
1. What is the best font and or what is the most standard font for subtitles? (Font size and other characteristics may be worth mentioning here too.)
2. Is it possible to have an outline around the text as opposed to shadow?
3. What are some general rules of thumb for subtitles that apply to broadcast and cinematic productions?
Thank you.

Writing games for US wireless carriers - general newbie question

I am a newbie to kvm and j2me so excuse me if these question are very basic or if i'm asking the wrong questions.
I have been asked to quickly research writing games in java for US wireless carriers. Ideally I'd like to pick a carrier (e.g. Verizonwireless) and find out more about writing for them. How should I go about researching this?
My research so far has found:
General j2me info:
I did some initial searching in the forum and found that the following link will give me a basic guide to j2me:
http://access1.sun.com/SRDs/access1_srds.html.
If I look at the documentation for -
- Java 2 Micro Edition (J2ME)
- Mobile Information Device Profile 1.0.1 (MIDP)
Is this still the best place to look at online?
Specific wireless carrier info:
I had no luck finding where I should look for information on specific
wireless carriers. Any suggestions? Also am I approaching this the right way or should I be looking at the specific java enabled mobile phones rather than the wireless carrier? Or is it a combination of the two?
Thanks for any help.

If the games are going to be networked then you should find out what type of network the carrier has (TDMA,CDMA,GSM with or without GPRS, etc. what bandwidths.... WAP or I-Mode). Regardless, you should be also concerned with what are the phones available on the carrier and what is their Java support.

Some general photo questions

I will be undertaking a major project soon that involves scanning all (and I mean every single one) of my family's photographs so that we have digital copies in case something bad happens to the originals. I plan on using iPhoto to store and catalog the photos. But my question is, when I scan the photos, what file format should I use? My scanner (HP Scanjet 3970) can scan to jpeg, tiff, tiff (compressed), bmp, and gif. which of those should I use? Also, I read somewhere that tiff for macs are different from tiff in windows. Is this true?
Also, what resolution is optimal for keeping an archive of photos? File size is not really an issue since I'll be using an external hard drive that's plenty big.

what file format should I use? My scanner (HP Scanjet 3970) can scan to jpeg, tiff, tiff (compressed), bmp, and gif. which of those should I use?
iPhoto will handle any of those formats. My suggestion for maximum compatibility is to choose between tiff (uncompressed) and jpeg. Why? they're pretty universal, regardless of computer. As to choosing between them? Well jpeg is a lossy compressed format, tiff isn't. The files sizes are huge with tiff, quite acceptable with jpeg. How much editing will you do? IF not much, then there is little re-saving and jpeg will be absolutely fine.

http://en.wikipedia.org/wiki/JPEG
Also, I read somewhere that tiff for macs are different from tiff in windows. Is this true?
Not that I know of.
Also, what resolution is optimal for keeping an archive of photos
The general rule of thumb is 300 dpi is what's required for printing. Screen images require less.

Pivot (Crosstab) question

Is there a way to use a function for column or row definition in a pivot (crosstab) table in a RTF template ?
For example, if our data set has a date field, and we want ta pivot table that has columns based on the year of that field, how would we create that pivot table? Accoirding to the BIP documentation, there is a function <?xdoxslt:get_year('2000-04-08', $_XDOLOCALE)?> that returns the year of a date field. Using this in the column definition, gives me a error. ie
changing
<?crosstab:c9827;"//G_1";"PRG_TITLE{PRG_CODE,o=a,t=t}";"PL_DATE{,o=a,t=t}";"AMOUNT";"sum"?>
to
<?crosstab:c9827;"//G_1";"PRG_TITLE{PRG_CODE,o=a,t=t}";"xdoxslt:get_year(PL_DATE,$_XDOLOCALE){,o=a,t=t}";"AMOUNT";"sum"?>
Using the XQuery conversion function year-from-date gives me again an error.
Of course, we could go ahead, and insert the year filed in our data and use it, but what we aiming is a general solution - is one exists .
Thank you

Thanks, again, but no it doesn't. Double-clicking (at least on my computer) merely collapses (or expands) the particular item in the pivot.
Oh, well. This would be a useful (and logical) feature. That is, while in the pivot table, when clicking (double-clicking, whatever), be taken to the original point in the worksheet (for editing purposes). It servers no logical purpose whatsoever to open
a new Worksheet.
It works perfectly OK at this end.
I disagree that it serves no useful purpose: its purpose is to provide a breakdown of the aggregated figure in the pivot and this is something that users often require (the ability to, "drill down" and see how a number is made up).
Go to my website:-
http://www.pierrefondes.com/
- and open item 201.
It should open to the Worksheet called:-
pivot_chart
Double click in cell:-
B4
- which has a total of:-
58
- in it.
A new Worksheet called:-
Sheet1
- should now open showing you how that:-
58
- is made up.
Does that help?

General iPhone Questions

Hello! I'm new, and I have a few questions about my new iPhone 3G. I'm hoping that this is the best place to ask them. A lot of these are shot-in-the-dark "Do they have this feature?" questions. Please answer whichever questions you can, and I'll try to figure out how to work this forum's points system and repay you!
Is there a way to turn off the Safari browser history? I turned off the Google search engine history and I know how to clear my Safari browser history, but I don't know how or if you can disable it completely. I also know about the "Broswer" app, but it doesn't save history at the expense of not saving passwords either.
Is there any way to set up a randomized wallpaper that changes each time you start your phone? Is there a way to set up a different wallpaper for each page of apps?
I see you can make grey background app folders, and you can fit a max of 16 apps/folders per page and 4 more at the bottom. Is that the default?
Is there any way to add a passcode lock to individual apps? I would love if, when you enter your start-up passcode to enter your iPhone, a certain password unlocks your phone normally while another password could enter a "guest" version without personal contacts or other personal data - but I doubt that's possible.
Is there a way to make Google as a homepage that opens by default when I open my Safari browser?
What exactly is airplane mode? I saw on a site that it blocks calls and texts? Is that right? Do you still get a general notification is someone calls or texts you?
The upper-left button on the side of the iPhone mutes it and turn vibrate off, right? How do you set your phone to vibrate only when you receive a call or text?
Is there a way to do a complete phone backup so I wouldn't lose any data if I lost my phone and then purchased a new one?

External Authentication general-type questions

Greetings all,
I was recently shown how to get Oracle to allow Windows NT Authentication the way SQL 2005 etc. can. I was able to get it working. It's actually simple, you just have to have this line in your SQLNET.ORA file:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
and make sure a couple initialization parameters are set (OS_AUTHENT_PREFIX to NULL and REMOTE_OS_AUTHENT to TRUE - the first can't be changed once the database is built!).
My first question is does Oracle support external authentications to operating systems other than NT, i.e. SUN, UNIX, LDAP etc? And is it a similar architecture?
Secondly, the only ways I've ever connected to Oracle are 1) through SQL*Plus, 2) Using OLE DB from Windows and 3) Using ODBC.
Is external authentication supported when logging in any way other than through OLE DB? If so, how?
Appreciating any general information!
Thanks
Joe

1. The name of the product is SQL Server not SQL. SQL is a language.
2. Oracle supports all major forms of internal and external authentication. The ones you listed and many more. The docs are at http://tahiti.oracle.com
3. External authentication is support across the board. But you've got to be working with a database holding nothing more important than your mother's cookie recipes to think that operating system authentication in a Windows environment is secure: It is not.
Your first responsibility, unless you are just playing games at home or in school, is to secure the data and that means an environment more secure than the one you've chosen.

Some General Slowness Questions

Hi there,
I've had my MacBook Pro since August 2006. I love it dearly, but in the past couple months (especially since I've upgraded to Leopard) it has been so, so, so slow. Dock taking forever to open programs, frequent appearances of the rainbow wheel of death, I've been needing to use Force Quit a lot due to frozen screens. I don't know much technical information about computers, so I've been at a loss to try to solve this problem. Some questions:
-As an insane college student, I tend to leave my computer on all night, and most of the time in general. I've heard differing opinions on whether this is good or bad. Should I be shutting down every night? Could this be a cause of the slowdown?
-Could it simply be a space issue? I'm using 60 of 74 available GB. iPhoto and iTunes in particular are slow and freeze a lot. I've tried looking at Activity Monitor, but I can't really figure out how to interpret its data. Looking at its processes list, Microsoft Office seems to be taking up a lot of work just when I have it open...right now Excel is using 38 MB (Real) and 1 GB (Virtual) of Memory. Firefox is using 885 GB of Virtual memory. It also seems that I have the PowerPC version of Office, not the Intel version (which is confusing because I bought Office with the computer)--could that be a problem?
-I downloaded an application called Cocktail and have been running it, I guess it's supposed to be a general cleanup type app, not sure if it's making any difference though.
-Sorry, I'm obviously pretty clueless at these things! Thanks for anyone who took the time to read this.

Okay, 512MB RAM, is your issue, you need at least 1GB to run OSX with any resemblance of snappiness. Using 80% of your drive is a fair bit, but not bad. Its good to have 10% of your drive free at any given time (the system will at times use about that much for virtual memory, although maybe more in your case since you have so little RAM). You might want to start looking through your files and see what you do an don't need, since you can fill up a few GBs fast in some situations (such as installing new programs, etc.)

Can I use coherence as follows? (General architecture question)

I'm working on creating a "web service" that will typically
- Receive a request and log it.
- Process
- Reply to "client" and log it.
The idea is to put the logs into the grid and finally to SOR?
Of course the logs need to be parsed, searchable etc...
Does the above make sense?
And some general questions...
If coherence is configured as partitioned do you really need a SOR, can it replace the SOR?
Can I have coherence running on seperate machines and the web service on other servers?

It makes perfect sense.
You can use a CacheStore to asynchronously ("write behind") to write your log entries to the system of record. You can implement a LogEntry class which would wrap the log messages, and expose getters for the attributes you wished to query by. You can configure an evication policy to determine how long LogEntry's should remain in Coherence.
So long as you have sufficient memory for the amount of data you wish to store (and backups, if necessary), yes Coherence can replace your SOR.
Yes, Coherence can run on different servers. Your web service layer can be configured as a "storage disabled" cluster member, or connect to the cache servers using Extend.
