How to swap two string variables without using a 3rd
variable?
Something like this.
Append A with B (so A equals "aabb")
Set B equal to a substring of A starting with the first character and ending at A's length minus B's length. (So B equals "aa")
Set A equal to a substring of A starting from B's length and ending at the end of A. (So A equals "bb")

How to compare two strings whether both are equal while ignoring the difference in special characters (example: & vs & and many others)?

I attempted to compare two strings whether they are equal or not. They should return true if both are equal.
One string is based on Taxonomy's Term (i.e. Term.Name) whereas other string is based on String object.
The problem is that both strings which seem equal return false instead of true. Both string values have different special characters though their special characters are ＆ and &
Snapshot of different design & same symbols:
Is it due to different culture or language?
How to compare two strings whether both are equal while ignoring the difference in special characters (＆ vs &)?

Hi Jerioon,
If you have a list of possible ambiguous characters the job is going to be easy and if (＆ vs &) are the only charracters in concern awesome.
You can use the below solution.
Before comparing pass the variables through a replace function to standarize the char set.
$Var = Replace($Var,"＆","&")
This is going to make sure you don't end up with ambiguous characters failing the comparison and all the char are "&" in this case.
Similar technique is used to ignore Character Cases 'a' vs. 'A'

Hello anacc,
Thanks for using Apple Support Communities.
For more information on this, take a look at:
iOS: Unable to update or restore
http://support.apple.com/kb/HT1808
Connect your USB cable to your computer but not to the iPhone, iPad, or iPod touch until step 3.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.
While pressing and holding the Home button down, connect the USB cable to the iPhone, iPad, or iPod touch. The device should turn on.
Continue holding the Home button until you see the Connect to iTunes screen. When this screen appears, you can release the Home button:
Note: If the image of a battery appears, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again. If you don't see the Connect to iTunes screen, try these steps 1 through 4 again.
iTunes should automatically open and display the following message:
"iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes."Note: If iTunes not open after two minutes, please open iTunes yourself.
Use iTunes to restore the device.
Best of luck,

How can I track my iPod without using an app ?

Hey I lost my iPod touch in school and I think one of my classmates took it how do I track it down without using an app ?

The only way to track it at all is to first have enabled an iCloud account on it before it was lost, with the find my iPod setting in that account's setting panel set to "ON".
If that was done, you can log in to your iCloud account in a web browser and you can try to track it. It must be on, and it must have an active wifi data connection to be trackable.
Without an iCloud account already on it though, there is no way to track it.

The only way to get 10.5 is to purchase it on CD. Such as http://www.amazon.com/Mac-OS-Leopard-10-5-10-51/dp/B0012RAVRC where is being sold for $179.99.
If your optical drive is broken, you will either need to replace it or get an external. There is no other way.
Why do wish to upgrade? As you can see it is going to be expensive, probably more the Mac is worth.

Hi,
actually there's none. The UITableView class needs to "know" the tableView's height so either it can calc <number of rows> times <row height> or it has to sum the height of each single row.
If the row which needs to be of different size always is the first or the last row you can user a tableHeader or tableFoot view.
