Some very basic queries about mac os

what is the diff between
alias n duplicate
get info n show inspector

1. Alias creates a shortcut to an item. Duplicate creates an exact copy.
2. The Get Info window opens for what's selected at the time the command was issued. Show Inspector changes with the selection.

Some basic queries about mac os

i m wondering to buy a mac n surely i will buy it soon but i had some ques
1) macs slows down with data as windows does ??
2) crashes or viruses are frequent ??
3) any technical issues with os ??
4) the advantage of windows over mac os ??

Note that you're getting a fairly dumbed-down view of the whole virus issue so far. People like to play word games with this topic. It's important to understand that malware does exist for the Mac, so that you don't let a false sense of security behave in dangerous ways. Of course, there's been several orders of magnitude less malware released for the Mac in the last 10 years than appears for Windows every day, on average, so you'll probably never see any malware... but it's still possible. For the full story on Mac malware, see my Mac Malware Guide. (Note that my pages contain links to other pages that promote my services, and this should not be taken as an endorsement of my services by Apple.)
Also, regarding whether the stock 13" MBP has enough memory for you, it is impossible to answer accurately without knowing what you plan on doing with your computer. If you're a graphic designer, for example, who needs a lot of memory and power, 4 GB may not be enough, and for that matter, a 13" MBP might not be right for you. What do you plan on doing with it?

Some very basic questions about calling a DLL in C[VI] code.

Hello everyone!
I'm sorry if this a really simple concept. I've come from a background of embedded systems, so DLLs are something I haven't really played around with much. Regardless. I'm developing an application in CVI for a project, and I generated a DLL that I want to use in Visual Studio 2013. I was able to compile it and it output the expected *.dll file. My question however is how do I properly import that *.dll into the CVI IDE? I did google and search the forums and I didn't find what I needed exactly.... I did find however this link: <http://www.ni.com/white-paper/8503/en/>. I did read through it all, and I think I'm going to try and use Implicit Linking. In the link it does detail 3 steps:
Include the import library (.lib) in your LabWindows/CVI project
Include the header file that contains the function prototype in your code using #include
Call the function in your code like any other function
I was able to easily complete step 1.. Now I'm on step 2. The headerfile that contains the function prototype of my code...I was looking at examples, do I just call the dll file as a .h file now? It seemed that way from what I saw. Do I need to output a header file for the DLL some how? Does the CVI compiler automatically reference that .h file with the lib that was imported?
Then in step 3...do I call the functions like they're in another file in the project? Just call the function as usual with the type and then feed the variables into the function and so on?
Sorry if this is a really rudimentary question.
Thanks in advance!
~Andrew

The header file definitely isn't the .dll renamed! While creating the .dll, your development environment (don't know which one you've used) should create both a .lib file and a .h file that you must use in your project if you want to go the static linking way. I see you've found the .lib file: the .h file should be available as well, possibly in the same path. The include file lists all the definitions for variables and functions exposed by the dll.
As per step #3 the answer is yes: you simply call .DLL functions like any other function in your program. At the bottom of the tutorial you've linked there is a link to a Developer Zone Example that is a complete CVI project that uses a .DLL: you may take this as a sample framework to study.
Proud to use LW/CVI from 3.1 on.

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

One very basic question about inheritance

One very basic question about inheritance.
Why we need inheritance?
the benefit of inheritance also achieve by creating instance of base class using it in other class instead of extending the base class.
Can any one please explain why we are using inheritance instead of creating object of base class????

One example of inheritance comes in the form of a vehicle. Each vehicle has similarities however they differ in their own retrospect. A car is not a bus, a bus is not a truck, and a truck is not a motorbike. If you can define the similarities between these vehicles then you have a class in which you can extend into either of the previous mentioned vehicles. Resulting in a reusable class, dramatically reduces the size of code, creates a single point of definition, increases maintainability, you name it.
In short there are thousands of benefits from using inheritance, listing the benefits could take a while. A quick Google search should give you a few hundred k if not million links to read.

VERY Basic Questions about Oracle eBusiness - what "languages" are used?

Please forgive the very basic nature of this post- (I have been in systems (IT) for over 20 years, so I do have lots of systems experience, but no exposure to this particular software.)
So here are the basic questions - I assume that much of the data base logic is written in PL/SQL, but what other tools / languages are the applications written in?
(Oracle Forms, Oracle Reports, Java, C, something else?)
With over 20 years and experience with a number of other packages, I can learn a great deal about an application by 1. Looking at the DB structures (charts), 2. looking into DB code (Packages, triggers, procedure, functions) and 3. Seeing the screen shots.
None of my customers have had Oracle eBusiness - that have had home grown applications or other COTS/packages.
can anyone suggest a place where an independent person can inexpensively get some exposure?
My sincere thanks for any answers/suggestions.

Some queries about MAC OS X LION

I want to know that after installing Lion, will my MS Office 2011 work? I also have a bootcamp partition which has windows 7 in it, So will that get affected after installing Lion?
How will i get back Lion if i need to format my iMac anytime as i will not have a DVD of it, so what is the procedure of that?
Wil i have all the data in my HDD or do i need to back up my files for installing MAC OS X Lion?
Thank You...

>How will i get back Lion if i need to format my iMac anytime as i will not have a DVD of it, so what is the procedure of that?

No upgrade can guarantee no data loss. You must backup your data if you value it.

How do I gather some very basic data from visitors to my site

I'm new to DW CS4, the learning curve has been steep but I'm getting the hang of it now. I have created an airshow website here (www.hollisterairshow.com ) which works just fine. I've been asked to add some basic questions to the web site (are you coming by car/ airplane,which day, camping overnight etc). I have a draft of the questions at the lower right corner here www.hollisterairshow.com/index2.html , they are very simple and all I need is to a total showing the sum of the answers, no login, no reservations etc. Ideally I'd like to have a submit button that changes to a "Thank you" message when a user has submitted their response and remains as a "Thank you" if they visit the site again. Do I need to set up a data source or something for this, I'm having a hard time figuring out how to start. So, what's the simplest way of implementing something like this?
Thanks
Tony

I've been reading up on JavaScript and think I understand how to do the coding for setting/ testing for a cookie which will tell me whether the user has already responded and allow me to display the questions or the totals, thanks. I'd prefer to not have potentially hundreds of e-mails that have to be read and answers counted. Can the totals just be stored on the website and incremented when the user presses "Submit"? The totals I would need are:
Saturday - #Autos, #Aircraft, #Other, #occupants
Sunday - #Autos, #Aircraft, #Other, #occupants
#campers
This is not a financial application and the results will not guarantee attendance, we're just looking for an idea of how many might come each day as this is the first time we've run this event, so this doesn't have to be a bulletprooof application. What is the simplest way to implement this?
Regarding enabling PHP is this just a yes/no option in the control panel or there other options for it? I don't have direct access to this because the City of Hollister owns the website, I'm just volunteering to create it so I need to know what to ask the city's web administrator for.
Thanks so much for your assistance,
Tony Babb

Very basic questions about hard drives

I'm upgrading from vintage Beige G3, so much of the jargon about internal drives is new to me.
My MacPro will come with an OEM 160 GB drive. I will use this for my primary boot drive -- OS and Apps. All my data, photo files etc. will be kept on my second/third drives. I do not plan any sort of RAID setup. Windows is going nowhere near my Mac.
For the extra drives --
1) SATA? SATA II? What's the difference and is it critical?
1a) What is a "raptor" drive?
2) Does size matter (we're talking about GBs here, guys...)
3) Reliability is more important to me than speed or noise. We're a long long way from any technical help or even UPS.
4) Do new drives need to be formatted before using them internally?
5) If I partition one of the extra drives so I can keep a clean, backup OS boot partition, I need to format it as GUID, correct? Or does that just apply to external firewire boot drives? Does it matter which partition will be the boot partition?
6) I've read discussions about firmware requirements for some drives. What's that all about?
I was leaning toward MaxLine Pro 500 GB drives, but have been reading (reading too much, perhaps?) and now have all the above questions/concerns. (Whatever happened to the good ol' days of "buy an IDE drive, insert, play"?)
Thanks for your patience with these questions. I need to get it right the first time because of our remoteness!

1. SATA 1 interface speed rated at 1.5 Gb/s; SATA II interface speed rated at 3.0 Gb/s.
2. Drive ratings/performance is determined by many factors. You can best find out about individual drive performance by visiting http://www.storagereview.com/ to see their benchmark results on various drives. You will also find some helpful comparisons at http://www.barefeats.com/.
3. As for drive specs see previous answer. Generally speaking within any manufacturer's category of drive models for a given size the fastest drive will be the most expensive. Manufacturer specs usually do not provide any idea about drive performance in real world situations. Only benchmark comparisons are really useful, and even those can be confusing.
4. Yes, you can boot an Intel Mac from an APM partitioned drive. You simply cannot install OS X from the installer disc because it will refuse to install on a drive that has not been GUID partitioned.
5. Some older Seagate 750 GB models were not working properly when installed in a RAID configuration on Mac Pro computers. Seagate provided a firmware update to fix the problem for those who already owned the affected drives.
I don't know where you got the idea that Intel Macs were "picky about such things." Nor that installing drives in a beige G3 was a no-brainer. The old beige G3 required a lot of mechanical effort to mount a new drive internally. You not only had to connect all the various cables, but if you had two drives on the same ribbon cable each drive had to be jumpered properly - one as MASTER and one as SLAVE. Some older ATA hard drives had two different jumper settings for a MASTER - MASTER solo and MASTER w/SLAVE. Some beige G3 models wouldn't even boot OS X unless it was installed on a MASTER drive. And, you could not install OS X on a large drive except by partitioning the drive with an 8 GB partition for OS X that had to be the first partition on the drive. RAIDs may work or not depending on if you ran OS 9 or OS X. At least to me that wasn't the "good old days" unless you were comparing installing ATA drives to dealing with SCSI. I would say that in your particular case you were lucky, and you never tried putting two drives on the same ribbon cable. Oh, and I forgot about the size limiting jumper on most ATA large drives to limit capacity to 32 GBs because that's all that was supported by FAT32. Oh, yes, and the beige G3's disk controller did not support drives larger than 128 GBs.

New whistles and bells all very nice, but I miss some very basic tools

Hi,
I have been een LR user since a lon time, and I need to say that I really like the changes to the Development module.
However I could not believe that we now have a bookmaking element, how sad is that while we are still missing some fundamental tools.
I honest can not undertsand why this book stuff has been selected , which professional photographer will ever use this ?
Instead I would like to have seen, utilities to correct perspectives and planes. Yes , the lens corrections can do a lot, but why not a Tilt/Shift feature ?
That would allow use to corrected architectural images (such lines etc.....) without having to bail out and correct it in CS (transformations).
Am I the only one that thinks this way, and just maybe AD will understand that they are spoiling the photographers tool for popularity .

Many "professional" photographers would make use of the the Book module ... I make books for my clients routinely ... mainly wedding albums. I have and use InDesign, it's a wonderful tool ... but frankly, ID is overkill for many photo books. Wedding albums generally use very little text (which is where ID really shines) however, the big problem is ID can't work with RAW files ... by being able to design my albums directly in Lr ... it would save countless hours dealing the the thousands of extra derivative files needed to use ID or other album software ...
Just the time savings of jumping from the Book module to the Develop module to make imediate adjustments to an image that would be instantly updated in the book can save hundres of hours in the course of a year for quite a few folks who earn a living with their photography ...
Lr is not all I want it to be. Nor am I as excifted about some features I don't use as often as others may do. Though I usually won't question those persuits or label them as frivolous. Quite often, too many "professionals" throw out that term and forget they are not the only ones earning an income in the process and that they should show a little more tolerance as development moves forward. There should be room for everyone and acceptance that we all have different needs to accomplish our goals.

Very basic questions about a db in windows

- I am very ignorant at windows and do not know where
to see the user groups, my system only has 1 user
(there is no oracle user and the oracle installation
was made with this only user). For me it has no sense
that there exists an ORA-DBA group because there is
no oracle user, but I repeat, I do not know how
windows manages users and groups.If you only have one user on your system and the install was done with that user, then chances are good the user is in the ORA_DBA group. You can find User and Group settings by right clicking My Computer and selecting Manage. You will find the users and groups under Local Users and Groups.

Very basic questions about SMC

I've never used SMC before and I have some basic questions. I'm trying to set up the Sun Management Colsole to manage LDAP users in accordance with the instructions in Tom Bialaski's book LDAP IN THE SOLARIS OPERATING ENVIRONMENT.
My questions are:
1) What's the difference between Sun Management Center and Sun Management Console?
2) The book references Sun Management Console 2.1, what's the latest version and where do I get it? Version 2.1 is already installed on my machine and running.

1) What's the difference between Sun Management Center
and Sun Management Console?This forum is for Sun Management Center:

Basic queries about Form Development

Hello Friends
i am bascially a web programmer and have done little bit VB programming and have idea of event driven programming.I have to help my younger cousin in his project assignment and i have no idea about few things which i think normal in all event driven programming.My Quries are as follows:
1)Retrieve values from text,comboBox
===============================
i create a form by using dataBlock wizard and it automaitcally creaed all text fields on form with dataBlock Name.
now i am writing a ButtonPRess trigger code and i want to retrieve textbox value by using following code
Declare
mytext varchar2(39)
BEGIN
mytext:=myFormBlock.textField
END;
but i am keep getting error identified myFormBlock.textField is not declared.How the hell do i retrieve the data?
2)Display data in ComboBox and manually create insert query on BUtton's press event.
===============================================================
is it possible that i manually create INSERT query in which i retrieve value from form's controls and execute it, rather calling create_Record method of form
kindly help me,i will be very grateful to you.

Thanks now i am encountering another issue.I am getting following error
FRM:40508:Unable to Insert Record
i have following table structure:
Name Null? Type
FACULTY_ID NOT NULL NUMBER(5)
FACULTY_NAME NOT NULL VARCHAR2(40)
and writing following code to insert record and execute query
INSERT INTO FACULTY ( FACULTY_ID,FACULTY_NAME ) VALUES (100,:BLK_FACULTY.FACULTY_NAME);
commit
and it is keep giving the error.One thnig i would like to tell that i ran Datablock Wizard and i didnt select Primary Field ,Faculty_id in that wizard for DISPLAY purpose yes i did select for data binding but not for display purpose because I want to send my sequence Id as Id entry.
Where am I going wrong?
Thanks

HT201496 Hai there. I am facing trouble with my garageband apple loops.i don't see apple loops in my browser since quite some time i don't know what has happened to it and how it happened . i just wanted to learn some of basic things about music.can you h

Hai there. i am having a trouble with the garage band apple loops to get into my macbook pro. . i had it some time back and i dont know where it has gone and how it get it back. is there anyone to help me to get the loops back into the browser . i will be grateful to you if some one can help me with it/ thanks.

First check, if you do not accidentally have hidden or filtered your loops:
Uncheck the "Filter for more relevant results" option in the Audio tab of the GarageBand Preferences.
And the drop down menu on top of the Loop Browser should be set to "Loops", not to some Jam Pack or other collection.
If you still don't see any loops, check if you have set your project to a special signature, like 9/8, for that no standard loops do exist.
Then check, if any loops actually are installed in your system Library: Depending on your GarageBand version you should find the standard loops in the Audio folder of your system Library (Application Support > GarageBand):
Your System Drive > Library > Audio > Apple Loops
If the Loops are installed, but GarageBand does not show them, you need to rebuild your Apple Loops Index: See the FAQ for how to do it:
Re-Index GarageBand's Loops
This requires two steps:
erase the old Apple Loops Index by deleting everything in
Your System Drive > Library > Audio > Apple Loops Index
and then rebuilding the Loops Index by dragging the folder containing all of your loops onto the Loop Browser in GarageBand.
If no Loops are installed in your Library, you will have to restore them from your Backup.

Léonie
