How do I return the displaysleep value from the console?

I know that I can do pmset -g to list all the settings, including displaysleep, but I  was hoping there was a command similar to that for the screensaver which only returns the numerical value:
defaults -currentHost read com.apple.screensaver idleTime
Any possibility there is a console function that will return the value only?
Thanks.

Hi RavensFan,
Thank you for your help.
I have seen this Max/Min function, and I tried it, but I get an error becuase my signal is apprently "dynamic data" and the max/min function accepts double precision data, so thats the problem I am encountering at this moment. I have modified the block diagram to convert the "dynamic data" into a double and then do the same thing you suggested, but I will test it tomorrow in the lab. 
I am currently working around this by using a numeric input, which the user would simply watch the sensor output over the calibration period and manually input that value into the formula.
Thanks again!
PackersFan btw...
Cheers

  • How to return a bool value from MyBrokerProcess

    To make MyPlugin work in Adobe Reader X in Protected Mode On, i have created a Broker Process(MyBrokerProcess.exe)
    Plugincode(C++)--->BrokerProcess(C#)---->Helper(C#)
    MyPlugin has 4 button, when i click on each button a Window(System.Window.Form) will open and perform its task.
    1.While i trying to close the ActivePDF document , if any of the Windows(System.Window.Form) is open i will display the message saying("Choose YES to Close this Window first Before Closing the ActiveDoc and Choose NO to continue without closing Window and ActiveDoc"). This is taken care in Helper Class(C#)
    2.If the user choose "Yes", then the Helper functin will return 'true' to MyBrokerProcess.
    3.Inturn  MyBrokerProcess has to return this bool value to the PluginCode(C++) which is the only place to  access Acrobat API function to close the ActiveDocument.
    Now i am clueless as to how i have to return this bool value from MyBrokerProcess to PluginCode. Or is there any other way to accomplish the above task. Please some one help me to solve this issue.
    Thanks in advance.

    Hi Richard,
    This is what i tried to do. But i couldnot make MyPlugin work in Protected Mode On.
    Plugincode(C++)<--->BrokerProcess(C#)<---->Helper(C#)
    I added a simple Process between Plugin(C++)code and Helper(C#)code.
    Previously it was like
    Plugincode(C++) <----> Helper(C#)
    Thanks and Regards,
    Chetan.

  • How do you return back one record from a NamingEnumeration

    how do you return back one record from a For Loop issue
    Posted: Jan 4, 2007 9:13 AM Reply
    I have the following piece of code and i want to be able to just return one item...
    that is return e.next(); but this line doesnt work for below what is wrong
    if (attrs == null) {
    System.out.println("No attributes");
    } else {
    /* Print each attribute */
    for (NamingEnumeration ae = attrs.getAll();
    ae.hasMore();) {
    Attribute attr = (Attribute)ae.next();
    System.out.println("attribute: " + attr);
    /* print each value */
    for (NamingEnumeration e = attr.getAll();
    e.hasMore();){
    System.out.println("value:- " + e.next()));
    return e.next();
    }

    At the end of the loop, the NamingEnumeration has no more elements. You need to call getAll() again.
    By the way, please use code tags (above the posting box). You've been here long enough to know that (judging by your registration date).

  • How Can I get multi column values from dynamic search help?

    Hi Gurus;
    I'm using dynamic search help in my program.
    I want to get multi column values from search help. But I dont know solution for this issue.
    I'm using F4IF_INT_TABLE_VALUE_REQUEST FM.
    How Can I get multi column values from dynamic search help?
    Thanks.

    Believe it or not, the same FM worked for me in a dynpro. I will try to explain here how it works in custom screen and then you can do your work for other screens or program types. I am not going to write my actual work but will explain in general.
    I have 4 fields (FLD1, FLD2, FLD3, FLD4) and i made the search based on FLD2 and when user click on a line (could be any field), then this would bring the line on to the screens.
    There are like 3 steps.
    You have your value_tab for my fields FLD1, FLD2, FLD3 and FLD4. This is just the data that we pass into the FM. (data: IT_VALTAB type table of ZVAL_TABLE)
    Next map the screen fields into an internal table (data: It_dynpfld type table of dselc ). I also have other internal tables defined  (just to keep it straight, i will be putting here) data:  It_return type standard table of ddshretval.
    Next step is to call the function module. Make sure you have values in IT_VALTAB.
    call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
            retfield        = 'FLD2'
            value_org       = 'S'
          tables
            value_tab       = It_VALTAB
            return_tab      = It_return
            dynpfld_mapping = It_dynpfld
          exceptions
            parameter_error = 1
            no_values_found = 2
            others          = 3.
        if sy-subrc <> 0.
          message id sy-msgid type sy-msgty number sy-msgno
          with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
        else.
          perform get_selected_fields tables It_return.
        endif.
    The code within the perform GET_SELECTED_FIELDS  - We need to map the result fields after user selects it. The code goes like this. This is step is to update the dynpro fields.
    I need a internal table as well as a work area here. like,
    data: lt_fields type table of dynpread,
            la_fields type dynpread.
      field-symbols: <fs_return> type ddshretval.
    so fill out LT_FIELDS from the IT_RETURN table
    loop at lt_return assigning <fs_return>.
        la_fields-fieldname = <fs_return>-retfield.
        la_fields-fieldvalue = <fs_return>-fieldval.
        append la_fields to lt_fields.
        clear: la_fields.
      endloop.
    Call the FM to update the dynpro
    call function 'DYNP_VALUES_UPDATE'
        exporting
          dyname               = sy-repid
          dynumb               = '1002' "This is my screen number. You could use 1000 for selection screen (hope so)
        tables
          dynpfields           = lt_fields
        exceptions
          invalid_abapworkarea = 1
          invalid_dynprofield  = 2
          invalid_dynproname   = 3
          invalid_dynpronummer = 4
          invalid_request      = 5
          no_fielddescription  = 6
          undefind_error       = 7
          others               = 8.
      if sy-subrc <> 0.
        message id sy-msgid type sy-msgty number sy-msgno
                with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
      endif.
    good luck

    I don't see an "dbms_repcat.do_deferred_repcat_admin('"RG_EARMS"') job.
    The RepGroup would be quiescing but not quiesced if there are active, uncomitted transactions.
    What is the error you get when you attempt to resume -- I guess that the groups are in the queiscing state ?

  • I just upgraded on May 11 and find I cannot open a fold for bookmarks. I research and bookmarks are my lively hood. How can I return the bookmark functionality?

    MS 7 and long time user of Firefox so this is the recent upgrade of May 11. Unlike the prior bookmark functionality, I cannot indicate I want to bookmark a link and designate a new folder for a new topic in two to three clicks. This is critical to what I do for a living. How can I return the prior format and be sure bookmarks are backed up automatically. Does going back to the older and more functional tool bar restore this? And why does clicking the bookmarks toolbar show getting started, most visited and the printer icon? Getting started takes one to a new user set of instructions. But there are no functional operations in the tool bar? I am not going to go thru a lot of commands, this should be a automatic as before.

    '' the bookmark facility is not functional in 29 ... Bookmark puts all bookmarks there into "recently bookmarked" ''
    It does not.
    It works much the same as the old system does. Or at least it should do and does do for me.
    * Carefully reads the following article so you are certain what should be happening '''[[How to use bookmarks to save and organize your favorite websites ]]'''
    # From an unbookmarked page click the bookmarks star.
    #* That results in the bookmark being added, and yes initially it is just as an unsorted bookmark. (No doubt that is where most people put most bookmarks)
    # IMPORTANT click the star a second time. (But not so rapidly it counts as a doubleclick)
    #* You now have the options you had in the old version of Firefox <br /> Create new folders <br /> Save to a recently used folder <br /> Show all bookmark folders - and expand nested folders
    If your bookmarks are not working possibly the file is corrupted in which case see
    * http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox#Damaged_Places_database
    I am hoping it is just that you are doubleclicking the star too quickly.

  • How do you return the number of Rows in a ResultSet??

    How do you return the number of Rows in a ResultSet? It's easy enough to do in the SQL query using COUNT(*) but surely JDBC provides a method to return the number of rows.
    The ResultSetMetaData interface provides a method for counting the number of columns but nothing for the rows.
    Thanks

    No good way before JDBC2.0. u can use JDBC2.0 CachedRowSet.size() to retrieve the number of rows got by a ResultSet.

  • How can I return the current Date in Java?

    I am new to Java, and basically I want to know how I can return the current date as a variable, so for example, I have declared the following date variable
    private java.util.Date currentDate;How can I return the current date, do I have to write a method? To be more specific, I need to write a setMethod, that simply returns the current Date in Java.
    Please point me in the right direction.
    Thanks,

    If all you want is a date for printing or displaying, the easiest way is to use Date as shown below. If you need something more complex, look at the Calendar API.
    import java.util.Date;
    class DateEx
         public static void main(String args[])
              Date now = new Date();
              System.out.println(now);

    its very important files!

    tis true
    I know, I always do that but I was in a rush to get somewhere and I was relying on my thousand dollar Mac to do some kind of recovery or something. I know Microsoft always keeps temporary files (I think Mac does too, part of me asking here in this forum was for someone to tell me where I can find those files) and when you go to open Office Works then it gives you the option of opening the last recent documents, saved or not saved.
    I usually copy paste into my emial just in case something goes wrong with the created document but I just didn't have the time to login and do all that My loss, you live and you learn, BUT still if ANYONE got any info on this, PLEASE DO CHIME IN *keeping the hope alive*

  • How do i clear the  console

    Hi Experts
    I need to know "how do i clear the console " and
    "how do position the mouse cursor in x and y coorditates in a console "
    Thanks in advance

    You don't. Or, it depends on the console. Depending on your point of view.
    Java doesn't directly control it the same way that it controls an AWT window for example. It just sends bytes to it. If the console is capable of interpreting bytes in such a way to clear the screen, then it can.
    Most consoles a person is likely to use will interpret VT100 commands. Look them up; try google. You can just output those commands and the console will do what they say, hopefully.
    Sending a control-L (bye 0x0c, I think) may do it. Try that.
    Or you can try the java curses library.
    All this may be wrong if you mean something by "console" other than what I think you mean.
