Will be the deletion of an interface control user also removes its children?

StackLayout *firstRowLayout = StackLayout::create().orientation(LayoutOrientation::LeftToRight);
    Container *firstRowContainer = Container::create().layout(firstRowLayout);
    Button *locationButton = Button::create().text("Location");
    TextArea *locationTextArea = TextArea::create().text("Heloo Hi How aer you ...thsi is for location based label. Hope this is long enough. well I don't think so but whaever");
    firstRowContainer->add(locationButton);
    firstRowContainer->add(locationTextArea);

If I delete the reference to the firstRowContainer it also delete the page layout, button and also the textArea and free the memory?

Yes, "delete firstRowContainer" deletes everything.

I usually format this way so the hierarchy is obvious:

Button *locationButton;
TextArea *locationTextArea;

Container *firstRowContainer = Container::create()
  .layout(StackLayout::create()
    .orientation(LayoutOrientation::LeftToRight))
  .add(locationButton = Button::create()
    .text("Location"))
  .add(locationArea = TextArea::create()
    .text("Heloo Hi How aer you ...thsi is for location based label. "
          "Hope this is long enough. well I don't think so but whaever"))
);

QObject::connect(locationButton, .....); etc

  • Detect if the time information dialog box controls user has been activated

    Hello

    I have to make a few changes to my project. I can't edit existing program blocks, so I have to find a way to detect if the user has pressed icon for user dialog box to set up (control type is Time Stamp). I have now, I can compare the current values with the values from the previous loop pass, but this isn't an option.

    I'm looking for some kind of property as active control node or something similar.

    It does not exist.  You can create your own time stamp control (like an XControl), or you can simply watch to see if the window is displayed. You can do the last using VI server functions or you can use the API of the operating system. For Windows, you can use the LabVIEW Windows utilities library.

  • To the number of decimal places control user input

    Hey everybody,

    I am all new to LabVIEW and just learn how it works. I was wondering if there was a way to allow user input to change the number of decimal places (the output of my function is infinitely extensible).

    I tried, but it did not work:

    Using a digital input, I appended a string with "%" + '[INPUT]' + 'f' with the number of function concat strings and string functions. I used the resulting string as the formatting string in the value format function.

    This doesn't quite work. The output should be something like "28.274", but instead, it displays "283f. Anyone know why? Is there a better way to do it?

    In addition, attach a picture of the front panel and diagram of block for clarity.

    (Yes, it's homework, but the assignment does not include allowing the user to adjust the number of decimal places, it's just something I would like to add.)

    Get rid of the number 2 for the width of your decimal string number.  It requires a space before a number to a number.  %. 6F is not equal to % .6f.  The string format don't quite understand the first format string.

    (PS.  It helps if you attach your VI.  In this way we can play with what you have rather than trying to recreate it from scratch.)

  • recover the deleted messages in Outlook express

    Original title: recovering deleted emails Inbox

    while trying to remove an annoying bing/inbox.com search engine that I managed to remove all my emails from the Inbox Outlook Express except todays.  Any chance of recovery?

    In addition to the other reviews, if the messages have been deleted from the deleted items folder or shift-deleted from the Inbox, then my DBXpress program (www.oehelp.com/DBXpress/) also has a 'recovery mode' option which will recover the deleted messages in the folder, but it cannot have been compacted.  If its compacted, then deleted messages are on hard disk clusters that are likely to be replaced.  Also, the text of the emails can be successfully recovered, as 4 bytes on each 512 gets overwritten when you remove, then images and attachments can be recovered in this way.

    Otherwise see Bruce's suggestions.  DBXpress has the extract from disk feature that could retrieve the messages intact.

  • Analytics data drive free space is less than 15% > Vcops begin the deletion of data

    Hello

    I'm new to vCOps, please bear with me.

    We have vCOps running in a configuration of test for about half a year now. Recently, he has been given these administrative alerts on the virtual analytical computer:

    «Storage disk (/ data) of free space is less than 15%.» vCenter Operations Manager will start the deletion of data to recover disk space. To avoid the automatic deletion of the data, add an additional drive.

    I was looking into that, but I can't understand what data are removed or how vCOps chooses to delete data.
    For example, VM Analytics metric history goes back only 3 weeks, some metric hosts history goes back to early August. Another metric story hosts return early September.

    So I guess that vCOps has been clear data to recover disk space, but...

    Is there a logic on what data are removed?

    Is there a documentation on that?

    We have 110 guests and about 1250 VM. What is the recommended size of the unit of storage/data?

    Thanks in advance.

    It will be cleaning older data of historical metrology.

    But if your installation is that fresh, more likely of allocated disk space is less than the recommended size.

  • Auditing of database to save the DELETE operation on a schema for all tables.

    Hello
    I'm using ORACLE DATABASE 11 g. I want to apply the AUDITING feature to save all DELETE operations happening on the tables in the schema.

    I did the following steps but dint got the correct output: -.

    I logged in the SYS as sysdba user and together
     alter system set audit_trail=DB,EXTENDED scope=spfile;
    then I ran this command to save the sql code that will use the privileges of DELETION
    AUDIT DELETE ANY TABLE;
    Then I bounced my DB and intended to test I created a table in the SCOTT schema and inserted 10 lines in there and then DELETE all the rows in it.

    According to the expectations, I check the view
    select * from aud$
    where spare1 like '%MACHINE1%'
    and USERID='SCOTT'
    order by ntimestamp#;
    The output I got is: -.
    34     168368     1     1          SCOTT     I-DOMAIN\MACHINE1     MACHINE1     100     0                                                                      Authenticated by: DATABASE; Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=2565))          MACHINE1                    5          21-DEC-11 07.02.58.621000 AM               0     928:5024     0000000000000000               983697018     <CLOB>     <CLOB>     
    But here I don't see the SQL that is generated in the last column.
    What I expected, it's that if I shoot a DELETE statement in the schema, it will get connected here and with the help of this point of view, I want to be able to see that what user of which machine run a DELETE statement and that the statement was?

    Please let me know what that step i have missed here.

    PS: - Watch the ACTION # 100 column, this is the DELETE action code. I have also consulted the view DBA_AUDIT_TRAIL but din't find any useful info their.

    Thanks in advance.

    Try instead:

    audit delete table;
    

    DELETE ENTIRE TABLE audit is audit use of the DELETE ANY TABLE privileges.

  • Why will not erase the deleted messages in Thunderbird in FACT?

    This problem does not exist on my other computer or my phone when I delete imap messages, but when I delete this computer, even if it appears in the Trash of Thunderbird folder on this computer, it is not actually go in webmail or on any other device. Any ideas? Thank you.

    Re: when I delete emails from Thunderbird on the computer in question, they appear in the trash on this computer, but they do not actually delete from the server, they remain in the original folder (Inbox, sent).

    Quote:
    It is ideal for a message erased on an IMAP account or visible in webmail or other e-mail clients. Deleting a message just sets a flag, and it's the interface chart user what to do when there is a message when this flag is set. However, once Thunderbird compact (expurgated) this folder, the deleted message shouldn't be visible more webmail or any mail client, because it has been deleted physically.

    IMAP accounts offer several options to delete messages that are not available in the accounts pop tools-> account-> server settings settings-> "when I delete a message" a choice for "Move to trash", "Mark as deleted" and "withdraw immediately".
    end of quote.

    More information about the different methods are detailed on the link:

    If you right-click on the eg: Inbox folder and select "compact", this should eliminate the traces of the deleted messages.

    to compact a file: right-click on a folder and select "compact".

    to compact all folders: file > Compact folders

    you set up the auto strike?
    Tools-> account settings-> server to select imap e-mail account settings: clean up ("Expunge") Inbox on exit that compress the Inbox folder when you exit Thunderbird. If you check 'Empty trash on exit' will also empty and compact the deleted items folder when you quit.

  • Thunderbird is lock on a message and I have to delete the Bellsouth otherwise it will download the same email over and over. How can I fix it?

    It started a couple of weeks. I noticed an email several times being downloaded. After reviewing the many things, I deleted the email on Bellsouth and Thunderbird then downloaded all my emails. Over time, he started doing this several times in a batch of e-mails. The download bar will say it is loading down 1 (or whatever the number) to say 71 messages. It can download 1 or more, then it stops downloading. I go to Bellsouth and remove the last downloaded message and click Get Mail in Thunderbird to start the process again.

    If I don't delete the last email downloaded when I hit Get Mail Thunderbird will download the same email again and stop. A few times it will start a download and work for an extended period and then stop the download without having to download a single mail.

    Before I tried to pull up in protected mode I ran C Cleaner and SpyBot just to see if there was something I picked up somewhere. I've not seen anything unusual, but had two programs clean what they find. Since their execution I've seen Thunderbird download some e-mails twice, but it's the download now. Don't know what that programs cleaned up that seems to fix the problem. So, for the moment, it looks like I agree.

    Thanks Matt. If it comes up again I'll give the protected mode a shot.

  • If I delete the files in iCloud will be they deleted from my computer as well?

    "I get the message" your iCloud-storage space is almost full.

    I can delete some folders from iCloud, but removing in iCloud will also remove the original from my computer?

    Thank you

    If you have the Apple menu > System Preferences > iCloud > iCloud drive in market, any file you save in iCloud drive automatically saves a local copy on your record player iCloud on your Mac, and it synchronizes to iCloud by car to https://www.icloud.com/

    If you delete the file or the other place that will not delete automatically from both locations.

  • Deleting the definition of Type casuses control a lot of misreferences and program in the block diagram errors

    In LabVIEW 2010, I have a Def Type control i.e. a Cluster with several other controls within the Cluster. Apparently, the references to the controls in the block diagram are based on the order that the controls have been added to the Type definition command. The side effect of this is that if a control is removed from the command of Type definition, many of the done Variable reference in the block diagram or now either broken, or worse still, refer to wrong control in the Type definition. These problems are quite difficult to find and fix.

    Comment: If you create a control of Type definition and make a Cluster. Now add any controls to the Cluster in an order, let's say A, B, C, D. Their types does not matter. Now use the Type definition in one or more controls on the front panel. In the block mark references to controls inside the Type Def would control on FP. Now return to the Type definition and remove the command B of the definition of Type. Now, lots of errors appear. Broken links. But worse still, you see old references to B that now refer to C and old references to C are now referring to the old references to D and D are removed altogether, etc..  This side effect is much more errors, broken links and misreferences than expected otherwise.

    How add and remove controls anywhere in a Cluster in a Type definition, at will, without creating a whole bunch of errors in program, broken links and misreferences for controls in the Type definition that have not changed?
