"c" key types without being hit
I have a MacBook Pro 17" late 2011 - the "c" key types without being hit. Any idea what could be causing this?
Probably a stuck key or some other hardware issue with your keyboard.

How can I stop emails from being sent without my hitting the "send" key.
Firefox doesn't do email, it's a web browser.
If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.

Using Firefox 4, my net emails are sometimes sent without my hitting the send key, before I am finished typing. I appear that they send when I hit the "enter" key for a new paragraph. I want to have them send only when I hit the "Send" key.

I have just bought a MacBook Air in Madrid, but the keyboard types, for example, ¿ when I hit shift and the semi-colon key, and = when I hit the ! key. What do I have to do to reset it to function normally?
Go>Preferences>Language & Text>Input Sources
Click off the flags of the countries you want--like if you need a British keyboard that has a British pound symbol, pick that one.
When you're done picking, them leave preferences. Now, in the upper right-hand corner of your computer, next to the date, you'll see a little flag. Click on that. You'll see all the flags you picked. Choose the one you want. Your keyboard will now give you the symbols, letters, etc. that you would get if you'd bought the computer in that country. -
Shift key randomly gets locked without being pressed (mbp 13" retina, late 2012)
I've been looking everywhere for answers for this problem, with no success (although many people raise similar questions on older models).
My MBP 13" retina 10.8.2 is new, clean, nothing spilled on it.
Ocassionally I connect it to external keyboard and mouse (USB or BT).
Regardless of that, sometimes the SHIFT key gets randomly locked - Without being pressed (whether the native keyboard, or when connected to external).
I could just be browsing the internet or be viewing a document in Word or GDocs, and suddenly - while mouse-scrolling - things will get selected, and the mouse-click becomes SHIFT-Click only.
When it happens, disconnecting/reconnecting the external keyboard or mouse has no effect - the problem persists.
The only workaround I found is to put it to SLEEP when it happens, and immediately wake it up.
The problem started a few weeks ago, and the behavior is completely random (it can happen twice in 10 minutes, or once a week).
Any ideas anyone?

Trying to switch primary displays without being able to see
my roommate has an Intel iMac Duo and the built-in monitor is not working. the image is totally obscured by tiny lines. only faint shades can be made out and it's not usable. he bought a miniDVI > DVI adapter and a DVI > HDMI adapter and connected his iMac to his TV. the TV was automatically set as the secondary monitor. so upon start up, his login screen is still on the broken built-in monitor.
so, my question for y'all is how can we set the TV as the primary monitor without being able to see what we're doing. to do this, we'll have to first log in, (which he said requires typing his user name and password). he tried to log in once by typing his name, hitting tab, typing his password, and hitting enter, but he didn't hear the successful login sound (sound was confirmed to be on by pressing the volume adjust keys). he left for work so i haven't been able to mess around with it. i'm thinking he may need to hit tab first, then type his username, then tab, etc...
can anyone help with logging in and/or changing the primary monitor? be creative!
much appreciated,
eric
oh ps, i don't know the exact version, but i know it's 10.6 also! if anyone can suggest a better place to post this question, that would be great too.

Welcome to Apple's discussion groups.
Depending on the Mac, the F7 or Command-F1 keys are supposed to toggle in and out of "mirror" mode, which shows the same thing on both displays. I'm not sure if that will help you or whether that will work without your being logged in. -
Hi. I installed Firefox yesterday as part of a work requirement. Since then, my Next G internet device will not work. How do I change the settings on Firefox without being connected to the internet? I have had to uninstall Firefox so I can use the internet.
Please help as I need both simultaneously. Thank you.Close your iTunes,

I have a hotmail email account and each time I click on a pdf attachment, Firefox asks me "What should Firefox do with this file?" I click "Open with - Adobe Reader (default)" then I check-mark "DO THIS AUTOMATICALLY FOR FILES LIKE THIS FROM NOW ON." When I check-mark that box a little line comes up beneath it that says "Settings can be changed using the Applications tab in Firefox's Options." So I also changed my application settings to "PDF - Use Adobe Acrobat in Firefox". Even though I have changed the application settings, and have check-marked the little box asking it to open with adobe reader automatically, Firefox still asks me each time I click on a PDF "What should Firefox do with this file". How do I make it stick that every time I click on a pdf attachment I want to VIEW it in Adobe WITHOUT being asked every time? Is there a way? Thank you!!!
Automatic actions are connected to a specific MIME type and if Hotmail doesn't send the file with a correctly recognized MIME type then the automatic action won't work.

You can enable battery % on ipod touch 4g without jailbreaking it you can use backup bot for itunes. Thats how i enabled it on mine. Step 1: goto http://www.icopybot.com/ibackupbot_setup.exe download and install it if you have windows. Step 2: Next create a backup of your device in iTunes and then CLOSE iTunes (or else you may run into problems later on) do not lock the backup with a password. Step 3: Open iBackupBot. Click the backup you just made Next click "Path" to sort by Path. Step 4: Look for Library/Preferences/com.apple.springboard.plist and double click it. On the registration screen that comes up, hit cancel. Step 5: Find <dict> and create a new line after it. Then add this:
<key>SBShowBatteryLevel</key>
<true/>
Step 6: Hit CTRL + S or just the save button at the top left corner of that editor window. Now close the window.
Step 7: Right click that same backup you just edited
Step 8: click restore
Step 9: Done! If you don't see the changes, reboot your iPod.

Price Difference Account being hit while making AP credit Memo
Hello Experts,
Price Difference Account is being hit while creating AP Credit Memo. I am creating an independent AP Credit Memo (i.e. without any base document). After posting A/P Credit Memo when I look at the Journal Entry it shows 99.43% of amount goes to Price Difference Account and the rest 0.57% goes to Stock account.
Help required please.
Thanks & Regards,
Edited by: Shahzad Nazir on Jan 19, 2011 5:54 PMHi Nazir,
This entry may have resulted because once you created the GRPO say for item A, the stock would have been consumed in production. And once you created Invoice and after that when you created credit memo, the system could not find the stock so it posted the difference in price difference account. Please run inventory posting list of the items in grpo to check the same.
Thanks,

Has anyone else had his/her phone alarm (on the clock app) go off by itself, without being set, and with a very weird sound?
Happened to me at 11:34 pm last night (Oct 28, 2013). I'm using an iPhone 5 with iOS 6. Sound was named something like "Orari" and sounded like a woo-woo ghostly alarm. I immediately swiped to stop the alarm and then deleted the alarm, which I had NOT set, but which seems to have set itself. The iPhone was plugged into my iMac at the time. There is no such sound on my phone or, it seems, anywhere (I Googled).
The night before, Oct 27, something similar happened to my iPad mini running iOS 6 ... also plugged in to recharge, but at a wall socket ... the sound was like a fire or smoke alarm.
I know it's Halloween week, but some of us need our sleep!
Any explanations?Hi Littleleslie,
Have you tried resetting the device (nothing will be lost): Hold down the Home and Power buttons at the same time and continue to hold them down until the Silver Apple appears (up to 30 seconds). Once the Home screen comes up, double tap the Home key and make sure you don't see the Alarm app in the list of background apps. If you do, swipe up on the thumbnail for it to close it out completely.
Then all you can do is wait to see if it will let you sleep through the night!
Good luck!
Cheers,

Re: Foreign key-type constraints
The methodology my company has defined and uses to attack this problem is
based upon looking for large grain 'business components' within the
business model.
When translating the functionality of the 'business component' to a
physical design we end up with a component object which usually consists of
a major entity(table) and several subsidiary entities and the services
which operate on and maintain those entities i.e. a component object.
We would then remove the referential integrity constraints only between the
components - to be managed by a component reference object - but internally
to the component leave the database referential integrity rules in place.
I beleive this maintains idea of encapsulation as the only way to
communicate with the component is through a defined public service
interface. It also lessens the impact of database changes as they are
usually confined to one componeet and the public service interface to any
other is left intact. It makes use of the database functionality without
dramatically effecting maintenance and performance by writing it all
yourself and/or defining every relationship with the refence manager.
It also leads very much to the definition of large grain reusable
components which can be used in many applications, important to a company
such as mine which develops software for others.
Unfortunately it is not always as simple as it sounds, the methodology helps.
Good database management systems with declarative referential integrity
will usuaually prevent you from defining circular references so you could
test for this by attempting to create the database before you remove the
inter component links. But circular references are much less likely with
the component technique properly applied.

First of all, we're not sure whether these constraints should be on the
database, because some would say that this represents business knowledge
which should only be in the app. Also, if constraints are on the
database, the errors you receive if they are violated may not be very
useful; i.e. we're using Oracle, and we'd have to map constraint names
in error messages to some more meaningful message to present to a user.
If foreign key-type constraints aren't on the database, what other
options do we have?
Let's say there's associations between objects X, Y and Z, whereby X and
Y both know about and use Z - we don't want to delete Z while X and Y
exist. I accept that Z should know how to delete itself, from
persistance, but how does it check for the existence of X and Y? If Z
asks objects of types X and Y to check whether they exist in the
database, you can end up with a circular reference. If you do the check
yourself, i.e. by having SQL checking existence of X and Y within the
delete method for Z, then I reckon you've blown encapsulation, and
you've also got a problem in relation to impact if the shape of your
database changes.
We're toying with the idea of having a central integrity manager, which
will tell Z whether it can go ahead with the delete, thus centralising
the integrity constraint knowledge within the app. and minimising impact
of changes to the shape of the database.
I'd be interested to know what others have done to address this issue,
and any thoughts you may have.

example, so bear with me...
Purists may argue with me here, but I must take issue with the notion that
your database cannot have any business knowledge. As soon as you define a
table, you have implicitly given the database business knowledge.
For example, suppose you define a database table Person, with columns Name,
ID, and BirthDate. You are specifically telling the database that there
exists a business "something" called Person which can (or must!) have
values called Name, ID, and Birthdate. You are probably also telling the
database about certain business rules: The value called ID can be used to
uniquely identify a Person; The value Name contains text, and has a maximum
length; Birthdate must conform to the format rules for something of type
Date; etc. Need I go on?
So, to me the argument cannot be that your database should not have any
business knowledge, but rather, what type of business knowledge should be
given to the database?
On the other side of the coin, I also take exception to the argument that
business knowledge belongs only in the Application. In fact, if your
discussion centers around whether business knowledge belongs in the
Application vs. the Database, then maybe both sides are still thinking in
two tiers, and you need to take a step back and think about your business
classes some more.
In our oversimplified example above, we set a limit on the length of the
Name attribute. This is a business rule, and so "belongs" to the business
class. However, our application class needs to have knowledge of that rule
so that it can set a limit on the length of data that it allows to be
entered. Likewise, the persistent storage class must have knowledge of
that rule to effectively store and retrieve the data.
We also have an attribute that is a Date, and a date by definition must
follow certain rules about format and value. The application class and the
storage class will both do their job more effectively if they know that the
attribute is a Date.
Does it break the rules of encapsulation if you allow the application class
or the storage class to have knowledge of certain rules that are defined in
the business class? If it does, then we might as well throw encapsulation
out the door, because it is a totally useless concept in the real world.
Now, let's think about the referential constraints. Suppose you want to
create a business class Employee which inherits from the class Person, and
adds attributes HireDate and Department. When you physically store the
Employee information in your Relational database, you might actually store
two tables, with the ID as a foreign key between them. In this case, the
foreign key relationship would clearly belong to the storage class and the
database. The business class should not know or care whether the Employee
information is physically stored in one table, or two, or twelve.
Now, let's add another business rule, that Employee Department must be a
valid department. To support this rule, you will create a business Class,
Department. For the sake of argument, let us say that the persistent data
for this business class will be stored in a database table, also called
Department.
We have said that there is a relationship between Employee and Department.
Which business class will contain the rule that defines the relationship?
Clearly, it is not Department. Department has no reason to know about
Employee, or any other class that might contain a reference to it. Since
Employee is the one that contains a reference to Department, you could
argue that the rule belongs there. That works fine, until you want to
delete a Department object. Obviously, you would not go to the Employee
class for that. So it seems that the relationship does not belong in
either class.
Someone has suggested that you have an integrity manager or some similar
class for that purpose. The integrity manager would have knowledge of the
rules that define the relationships between your business objects. This
allows you to keep your OO design more "pure" from the standpoint of
encapsulation. Conceptually, this makes good sense, since the relationship
between two classes does not belong to either of the individual classes.
Let's hold that thought for a minute.
Now let's think about your physical database design. I am betting that
there is a high degree of correlation between your database tables and your
business objects. It won't be 100%, because, among other things,
relational databases do not deal well with the concept of inheritance. But
if there is a very wide divergence, then I would need to question the
validity of your design. With that in mind, I am going to propose that you
already have an Integrity Manager, and that is your relational DBMS.
My position is this, that it is ok, even necessary, for the data storage
class to have knowledge of the structure and relationships of the data. It
needs this information to effectively do its job. From my point of view,
saying that you cannot tell the database that there is a relationship
between Employee and Department is just as pointless as saying that you
cannot tell the database that a certain column contains a date, or that
another column contains a unique key which should be used as an index.
Would you argue that an index implies business knowledge, and therefore
does not belong in the database? On the other hand, you could argue that
referential constraints always belong to the physical storage classes,
since they describe under what circumstances data can be stored or deleted.
Now, for performance or other reasons, you might choose not to implement
the Employee-Department relationship in your physical database, and that's
ok, too. Maybe you have decided that since you do not delete departments
very often, that you do not want to incur the database overhead to maintain
the foreign key relationship. Or maybe you have determined that the
Department data will be stored somewhere else other than the database.
Perhaps you would create an Integrity Manager instead, that would only be
invoked when you wanted to delete a Department object. The point is, if
you create an Integrity Manager, be sure you do it for the right reason,
and not because someone has mistakenly decreed that a database cannot have
any business knowledge.
This brings us to the other question, which is: What do you do with the
error if the constraint is violated? Consider this as an option: Create a
User-defined exception named DeleteFailed or something like that. Then it
does not matter if the error comes from the database manager or a separate
Integrity manager. In either case, you fill the exception object with
whatever meaningful data is appropriate, and raise the exception. The
application, which knows what it was trying to do, can listen for the
exception and deal with it appropriately. (btw, this is a good way to deal
with other predictable database exceptions as well, such as DuplicateKey,
or NotFound - your application need not listen for a particular SQL Code or
SQL State, which might tie it to a particular database or storage format.)
I do not see a problem with using the DBMS to define relational
constraints. That is, after all, what a Relational database does. You do
not need an integrity manager for OO-purity, but you can use one if it
makes sense for other reasons. You should be able to change the method of
enforcing the relationships, or even change the entire DBMS without having
any impact on the application classes or the business classes. If you can
meet that test, then as far as I am concerned, you have not violated any
rules of encapsulation.
Any rebuttals?
