Need help with case.

Hi,
I have spent since Sunday playing phone tag in regrades to my case. I called yesterday and explaned everything about my case to a supervisior and was told it would be handled and I would receive points to my account for $25.00. I was not given a case number, but was told it was put into the system. So far, nothing was been resolved. I am losing faith and patience in this and need some help.
Thanks
Chris

  • Still need help with case sensitive strings

    Hello guy! Sorry to trouble you with the same problem again,
    but i still need help!
    "I am trying to create a scrypt that will compare a String
    with an editable text that the user should type to match that
    String. I was able to do that, but the problem is that is not case
    sensitive, even with the adobe help telling me that strings are
    case sensitive. Do you guys know how to make that comparison match
    only if all the field has the right upper and lower case letters?
    on exitframe
    if field "t:texto1" = "Residencial Serra Verde"then
    go to next
    end if
    end
    |----> thats the one Im using!"
    There were 2 replys but both of them didnt work, and the
    second one even made the director crash, corrupting even previously
    files that had nothing to do with the initial problem..
    first solution given --
    If you put each item that you are comparing into a list, it
    magically
    makes it case sensitive. Just put list brackets around each
    item.
    on exitframe
    if [field "t:texto1"] = ["Residencial Serra Verde"] then
    go to next
    end if
    end
    Second solution given--
    The = operator is not case-sensitive when used on strings,
    but the < and > operators are case-sensitive.
    So another way to do this is to check if the string is
    neither greater than nor less than the target string:
    vExpected = "Residencial Serra Verde"
    vInput = field "t:texto 1"
    if vExpected < vInput then
    -- ignore
    else if vExpected > vInput then
    -- ignore
    else
    -- vExpected is a case-sensitive match for vInput
    go next
    end if
    So any new solutions??
    Thanks in advance!!
    joao rsm

    The first solution does in fact work and is probably the most
    efficient way
    of doing it. You can verify that it works by starting with a
    new director
    movie and adding a field named "t:texto1" into the cast with
    the text
    "Residencial Serra Verde" in the field. Next type the
    following command in
    the message window and press Enter
    put [field "t:texto1"] = ["Residencial Serra Verde"]
    You will see it return 1 which means True. Next, make the R
    in the field
    lower case and execute the command in the message window, it
    will return 0
    (true).
    Now that you know this works, you need to dig deeper in your
    code to find
    what the problem is. Any more info you can supply?

  • Need help with case structures- please help :)

    Hey all.
    I'm currently trying to program a infrared furnace. I'm setting a temperature, subtracted my set temperature from the actual temperature (thermocouple hooked up to SCB-68), and voltage is being sent to the controller of the furnace accordingly. However, I need to hold the set temperature for a certain amount of time. I need help programming this: when the VI reads the set temperature from the thermocouple, it results in a timer running down. When the timer runs down to 0, the While Loop ends. I'm thinking case structures is most appropriate, but if you have a better suggestion, please let me know.
    Thanks

    You should probably implement a state machine.
    The state machine would keep track of the temperature and making ajustments on a timely basis.
    There is a template of a state machine is you select under the File menu > New > From Template.
    You can also look under Help > Find Example > and do a search for state machine.
    There are lots of state machine examples on this forum, some of which may be quite useful.

  • Need help with case cracking - Defect?

    I have a macbook (white) a1181 that I purchased in 2008...
    I handle my computers very delicatly and if they travel with me, they are packed very well with support...
    The body (case) of the laptop back by the fan underneath has a long hairline crack.
    There is also one where the front lip is as well.
    NOW,
    Apple Genius Bar wants ME to pay outright to get it fixed.
    It was not my fault at all!!!!! And it was not accidental damage either.
    SO I called Apple who wouldn't help me because I don't have phone support Or apple care. So if I pay the $50 for phone support, they'll tell me the same thing they told me in the store the operator told me.
    FIRST OFF, I didn't know that my Apple Care expired and even if I had it, it wouldn't really help me I was told...
    I paid so much money for this laptop and scrimped and saved up and I feel like I'm being dragged through the mud.
    I need to contact someone higher-up ASAP - this is absolutely ridiculous.
    I did not do anything to cause this cracking..
    I am so upset as I really saved up for years for this computer only for 3-4 years later for it to be cracking worse and worse. I paid so much...
    Any advice or help would be greatly appreciated.
    Thanks,
    aj

    Did you ask to speak to a manager while you were at the Apple store?

  • Need help with case/mount

    I'm looking for something to hold my iPhone in the glove box of my BMW. Thx

    I use an older fourth gen iPod in my BMW and always leave it in the glove box. I found the original Apple iPod semi-hard case with belt clip that used to come with iPods at that time.(no such accessories included these days unfortunately) I have my iPod safetly inside it inside the glove box. In that case it does not roll around.
    I think you can still but these cases zt Apple stores. Else something like that type of case to protect the iPod would be all you need.

I am using oracle 10g.
    thanks.

    figured out myself. Thanks.

  • Need help with a currently "in-use" form we want to switch to Adobes hosting service

    Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of.  I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our  "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit"  issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
    We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
    I need to get this right and working for the majority of my users and on any platform and OS.
    You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
    (and you will probably get right to me, unlike my and I'm sure most other folks',  "Adobe phone-in experiences")
    Thank You,

    Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
    So  I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself,  I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products"  to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
    OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi  & so on)...and if you are still on my site.. go to any  "GO RIGHT TO OUR ORDER PAGE"  button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is,  how do they select their individual colors within that (whatever) pack?... .
    So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a  " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
    So after thinking this all out,  and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
    Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year,  I think...its called http://pdf-fillableforms.com/.
    A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however,  if you're on MAC OSX or similar...
    I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
    OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending"  with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly,  and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add)..,  except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form....  Many folks report to us the following issues that we know of.  First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
    Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
    It almost always generates some kind ( at least one time)  of "error message" which we do warn them about..., telling one,  basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it...  and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
    Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly,  the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4)  If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
    Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that?  Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...

    I need to find the greatest grant year for the grant by a period parameter.
    once i find the greatest year i need to check the value of period 14 for that grant for the previous year and add it to the budget amount for that grant. however if their is an entry in the greatest year for period 00 then i need to ignore the period 14 of previous year and do this calculation current period +(current period - greatest year 00)
    hope that makes sense so in other words with the new data above. if i was querying period two of grant year 11. i would end up with $800
    because the greatest year is 11 it contains a period 0 with amount of $400 so my total should be
    period 2 amount $ 600
    period 0 amount $ 400 - period 2 amount of $600 = 200
    600+200 = $800
    if i query period 1 of grant 360055 i would just end up with 800 of grnt year 10.
    i have tried to modify that query you supplied to me with no luck. I have tried for several day but im embarrased to say i just can get it to do what im trying to do .
    can you please help me out.
    here is the query supplied by frank kulash who gracefully put this together for me.

    ;Miguel

    Hi, Miguel,
    Are you waying that, when the greatest year that has :given_period also has period='00' (or '0', or whatever you want to use), then you want to double the budget from the given_period (as well as subtract the budget from the '00', and not count the pevious year's '14')? If so, add another condition to the CASE statement which decides what you're SUMming:
    WITH     got_greatest_year     AS
         SELECT       TO_NUMBER (fgl_grnt_year)     AS grnt_year
         ,       fgl_period

  • Need Help With File Matching Records

    I need help with my file matching program.
    Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
    When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
    Here is my following program code:

    I am not sure what is wrong with my code above to make my results different from the correct results.
    Much help is appreciated. Please help.

    From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
    As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
    Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
    Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.

  • I need help with a VB Application

    I need help with building an application and I am on a tight deadline.  Below I have included the specifics for what I need the application to do as well as the code that I have completed so far.  I am having trouble getting the data input into

    •I need to use the OpenFileDialog and SaveFileDialog in my application.
    •Also, I need to use a structure.
    1. The application needs to prompt the user to enter the file name on Form_Load.
    2. Also, the app needs to use the AppendText method to write the Employee Data to the text file. My project should allow me to write multiple Employee Data to the same text file.  The data should be written to the text file in the following format (comma
    delimited)
    FirstName, MiddleName, LastName, EmployeeNumber, Department, Telephone, Extension, Email
    3. The Department dropdown menu DropDownStyle property should be set so that the user cannot enter inputs that are not in the menu.

  • Need help with home work see what you got

    1. The MEMBERS table has the phone number broken into three fields:
       CountryCode - e,g., '1' for the United States
       AreaCode - e.g., three digits for the United States
       Phone - e.g., 7 digits, with or without a dash between the first three digits (Exchange) and last four digits (Line)
       Any or all of the fields may be missing (null) or blank or contain only spaces.
       Write a T-SQL statement to concatenate the three fields into a complete phone number
       with the format: CountryCode(AreaCode)Exchange-Line, e.g., 1(816)123-4567
       If no Phone is present, return a blank string.
       If no area code is present, return only the Phone number. Do not return an empty pair of parentheses or the CountryCode.
    2. The PERSON_CAMPAIGN table contains a row for each war/conflict the member served in. A member may have served in multiple conflicts
       For this purpose, each row contains:
       PersonID - unique member identifier
       Campaign - name of war/conflict
       Write a T-SQL statement to return one row per member with all campaigns concatenated into a single field and separated by commas
       E.g., PersonID    Campaigns
             12345678    Global War on Terror, Iraq, Afghanistan
    3. The MEMBER_STATISTICS table contains one row per post.
       For this purpose, each row contains the post's:
       Division - a way of grouping posts by their member size
       Department - the state in which the post is located
       PostNumber - unique post identifier
       Reinstated - count of members whose annual subscription had lapsed for at least two years but who have now subscribed for the current year
       Write a T-SQL statement to determine the top ten posts in each division based on the number of reinstated members, with a minimum of 50 reinstated members.
       Rank them by highest to lowest reinstated count.
       Return their Division, Rank, Department, PostNumber, Reinstated

    I got 3 home work questions think i have the first two need help with the last one please.
    Kinda stuck on #3 hard I can see data not sure witch to sum or count?

       If no area code is present, return only the Phone number. Do not return an empty pair of parentheses or the CountryCode.
    ANSWER******************
    Notes: created a funtion to format the phone 
    Then used the this function in a select to concatenate Phone 
     CREATE FUNCTION dbo.FORMATPHONE (@CountryCode int, @AreCode int, @Phone VARCHAR(14))

  • Need help with calculator project for an assignment...

    Hi all, I please need help with my calculator project that I have to do for an assignment.
    Here is the project's specifications that I need to do"
    """Create a console calculator applicaion that:
    * Takes one command line argument: your name and surname. When the
    program starts, display the date and time with a welcome message for the
    user.
    * Display all the available options to the user. Your calculator must include
    the arithmetic operations as well as at least five scientific operations of the
    Math class.
    -Your program must also have the ability to round a number and
    truncate it.
    -When you multiply by 2, you should not use the '*' operator to perform the
    operation.
    -Your program must also be able to reverse the sign of a number.
    * Include sufficient error checking in your program to ensure that the user
    only enters valid input. Make use of the String; Character, and other
    wrapper classes to help you.
    * Your program must be able to do conversions between decimal, octal and
    hex numbers.
    * Make use of a menu. You should give the user the option to end the
    program when entering a certain option.
    * When the program exits, display a message for the user, stating the
    current time, and calculate and display how long the user used your
    program.
    * Make use of helper classes where possible.
    * Use the SDK to run your program."""
    When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
    when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
    Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??

    Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??You cannot restrict the user. It is a sad fact in programming that the worst bug always sits in front of the Computer.
    What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
    AND you might want to ask yourself why the heck a calculator needs to know the users Name.

  • Need help with almost completed plugin engine project

    Hi all,
    For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
    What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
    Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
    Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
    Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
    The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
    I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
    Look forward to some replies.

    Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
    On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces.

  • HOW DO YOU GUYS DEAL WITH APPLE.. SO CONFUSING...NEED HELP WITH SPECS FOR PURCHASE OF IMAC 21.5

    Hi guys, been reading your forums, blogposts, etc and am getting more confused.  I'm just a video girl trying to produce meaningful content through web videos for small to mid sized businesses and want to come over from the dark side. 
    Good news,, I dont need a super giant system,  I do simple editing for web videos, minimal graphics, no motion graphics, no animation etc. currently using CS4, will probably end up with 5.5.
    I want to get imac 21.5 or 27 if i have to..  So here's the question we all have,,, what do I really need besides an Apple fairy godmother to figure this crazy stuff out?????
    I want to be able to have firewire add on, but the rest is what I need help with.   So i've been looking at cs6 specs, even though im not there yet, eventually will be,, so just need to run cs4 now and build from there.  I also want to eventually move to final cut down the road so I want imac able to upgrade to final cut.
    WHAT DO I REALLY NEED MINIMALLY FOR NOW?  WHAT CAN I GET LATER IF i CHOOSE TO DO MORE AND NEED MORE POWER?
    cs6:
    Multicore Intel processor with 64-bit support
    Mac OS X v10.6.8, v10.7, or v10.8**
    4GB of RAM (8GB recommended)
    4GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
    Additional disk space required for preview files and other working files (10GB recommended)
    1280x900 display
    7200 RPM hard drive (multiple fast disk drives, preferably RAID 0 configured, recommended)
    OpenGL 2.0–capable system
    DVD-ROM drive compatible with dual-layer DVDs (SuperDrive for burning DVDs; Blu-ray burner for creating Blu-ray Disc media)
    QuickTime 7.6.6 software required for QuickTime features
    Optional: Adobe-certified GPU card for GPU-accelerated performance
    Any responses would be great.  I know you guys are busy answering the really high end tech questions

    All the current iMac models (both 21.5" and 27" with OS X Mt. Lion 10.8) will run CS4, 5.5 and 6 just fine.  They will also run Final Cut Pro X just fine.  Ditto for most any application you may want to use.
    Below are some notes (specific to your apparent requirements) that may help you with your purchase decision:
    Notes on purchasing a 21.5" iMac
    All 21.5" iMacs come with 8GB RAM but you cannot add more later.  I strongly suggest getting the maximum RAM (16GB) when you order the iMac.
    The basic hard drive is a 1TB 5400rpm drive.  It will work fine with Adobe CS but you will probably want the added speed of the optional 1TB Fusion drive for better performance. Some people will recommend/argue for one of the optional SSD drives instead, but they are very expensive and still only come in relatively small capacities - I don't recommend the SSD drives.  Get the Fusion drive and spend any extra money on a good external hard drive for backup and/or extra storage instead of an SSD.
    Notes on purchasing a 27" iMac
    All 27" iMacs come with 8GB RAM and you can add more later, up to 32GB
    The basic hard drive is a 1TB 7200rpm drive - it will be fine with Adobe CS.  There are upgrade options to a 3TB 7200rpm drive or a 1TB or 3TB fusion drive - these will be fine also.  There are also SSD drive options, but I do not recommend them. (Same comments as above.)
    Notes on all the current iMacs
    iMacs no longer come with built-in CD/DVD drives.  If you need one, you will need to purchase the Apple Superdrive accessory drive ($79)
    All of the iMac graphic processors (GPU's) are compatible with Adobe CS 4, 5.5, 6
    It is very difficult to impossible to change or upgrade the hard drive later on, so don't buy low-end thinking you can add a better internal hard drive later.
    Be aware that Macs always come with the latest (most recent) version of OS X.  And OS X Mavericks (10.9) is due to be released soon (in the next month or two).  There is no guarantee that the older Adobe CS 4 or 5.5 versions will run on OS X Mavericks.  If you cannot upgrade to CS 6 in the near future, you may want to purchase now rather than after OS X Mavericks is released.
    For what it's worth, I'd recommend the 27" iMac if your budget can afford it.  You will appreciate the larger screen size and added capabilities over the years you will use the computer.

  • Need help with boot up password

    Hi I need help with my IBM G41 think pad I when to sleep one night and I put some papers on the keys then close the lid with the papers in between on top of the keys now I get need a password when I started my PC can some some help me with this . Or is there any one whom had this some problem . I see a lock on the screen .

    Sorry if this seems like a stupid question, but why don't you have the password already? did the computer just randomly lock you out of it? If that is the case, that would be really strange. If there is no bios password on the computer, you should be able to reset the password in the bios.
