How can I erase the last char of string

I have a string tha is printing as following
129.111.13.1.
I want to erase the last "." can somebody helpme?
Thanks

You will have to create a new String. Then you can get the string length. Then you will need to to use a substring to get the positions you want.
Something like this
String Orginal = "129.111.13.1.";
String new_orginal = null;
int num;
num = Original.length();
new_orginal = Original.substring(0,num-1);
I hope it helps

    Thanks

    You'll probably have to call CSS on this one as this not normal by any means. The messages you noted above are completely normal but if that's all you are seeing then there's an issue.
    Have you reviewed wcm.log and wsusctrl.log?

  • How can I see the last location of a now dead ipod touch 4G that had find my iphone turned on?

    How can I see the last location of a now dead ipod touch 4G that had find my iphone turned on? I can see my macbook but I cant see the last location of my ipod touch. I lost it a few weeks ago and figured it would show up. But it has not and I need it again for my job. Please help.

    There is nothing you can do now. There are apps available from the app store that would give you that information if installed before it was lost/stolen.

  • I have an Ipod touch updated to last available ios 4.2.1. How can I get the last compatible versions of the apps?

    I have an Ipod touch updated to last available ios 4.2.1.
    How can I get the last compatible versions of the apps?
    In the appstore there are only the lat app versions, most of them are incompatible with my device.
    I know that previous versions of these apps were compatible with my ipod.
    Can all download them someway?
    thanks

    The problem is: I never had the compatible versions. But I want them, I'd buy them if I could.
    So I'm stuck with my Ipod, which can't be upgraded anymore to higher IOS versions, and with the appstore, that does not offer older versions; versions that have existed and still exist, perhaps in the recycle bin of some users, or somewhere in the appstore servers.
    I know, its a policy, just to sell more devices. Will not work with me. I'm not buying more Ipods

    You put the internal drive in an enclosure. If you choose to keep the drive, you don't need to erase it.

  • How can I erase the pictures in my iphone4s

    How can I erase the photos in my phone.

    It depends on where the photos are.  If they're in your camera roll (taken on your iPhone), you can delete them on your iPhone individually.  if they're in Photo Stream, you can also delete them on your iPhone (trash can in lower right).  Generally in other cases, you delete them on your computer and then sync.

    You can try that procedure but I'm not sure how far that factory reset goes on those phones.  I know the 7940/60 series you can blow out everything except the CNU which would do exactly what you are looking for.

  • HT201441 if the employee has been terminated and I need to reuse the phone and have no ability to contact them, how can I erase the phone?

    if the employee has been terminated and I need to reuse the phone and have no ability to contact them, how can I erase the phone?

    Welcome to the Apple community.
    Contact AppleCare (or Apple ID Support), upon speaking to an operator you should explain that your problem is related to your Apple ID, this way you will not be charged for assistance, even if you don’t have an AppleCare plan.
    I'm not exactly sure what procedures are in place for such events but Apple can assist in such cases, but it may take a while and you may need to provide proof of purchase and other corporate documents.
    For future reference your best tactic might be to use Apple Configurator to set up all your companies devices. You can set the password for 'Find my Phone' to be identical for all your devices, whilst allowing the user to use their own password for the remainder of the iCloud services.

  • How can I find the last day of the current month

    Is it possible to get the last day of the month in reports. Suppose I enter JUL in one of the text field. Now in reports I want to show that JUL contains 31 days. How can I retrieve the last day of the month.
    Any ideas?

    The first (and fast) solution I think is this:
    There is a function MONTH(CURRENT_DATE) that returns the number of the month of the current date.
    Now, you could use CASE WHEN expressions to determine the number of days returned since you now how many days does every month have.
    For instance, you could do:
    CASE
    WHEN MONTH(CURRENT_DATE)=1 THEN 31
    WHEN MONTH(CURRENT_DATE)=2 THEN 28
    WHEN MONTH(CURRENT_DATE)=3 THEN 31
    WHEN MONTH(CURRENT_DATE)=4 THEN 30
    END
    PD. This is faster that use OR expressions like 1 or 3 or 5 because you dont have to try every option.
    Hope it helps...but maybe there is another way more automatic.
