validation of maximum size on the element of text box

Hello
I couldn't find any station associated with this type of validation. I have a text box on a form. the maximum size of the associated database column is 512 bytes. I need a sort of validation that will tell the user that the maximum size is 512. currently the text box allows the user to write as muc has he wants and throws his mistake if he spends more than 512 bytes.

ORA-20505: DML error: p_rowid = 63, p_alt_rowid = MEMBER_NOTES_ID, p_rowid2 =, p_alt_rowid2 is. ORA-12899: value too large for column 'DW_PROD '. "" "" MEMBER_NOTES '. "" NOTES_TEXT' (real: 1016, maximum: 512) ORA-02063: preceding the line of DATA source
Error failed to process row in the MEMBER_NOTES table.

None of graceful.

Any thoughts?
Thank you.

Hello

You can use the Type of 'text box with character counter.

Hope this helps,

John.

  • Is there a maximum size or the limit of text file during storage and data transfer?

    HI -.

    We used WriteExtFile and AppendExtFile to store data in a CSV text file in a data folder in the same location as the executable files of Authorware.

    WriteExtFile ("data\\"^"Variable_Names.txt", Survey_Variable_Names)

    AppendExtFile ("data\\Survey_DATA.txt", Survey_Data)

    As a general rule, we always put our executable files on the hard disk of the computer (c) due to some issues we had with an incompatible network drive in the past.  Have the files on the C: drive, eliminated any network problem.  Our data has accumulated would be always stored on the C: drive as well.

    Now, we need to store a backup copy of the data on a server, on the C: drive.

    My question is: is there is a maximum file size that can be "read in" and then "written" using Authorware?

    My thought was to use ReadExtFile to read the content of the 'Survey_DATA.txt' file and use WriteExtFile to write these same data on a drive on the network, by adding the date and time at the end of the name of the file as a backup file.

    I used this logic, which is working to write on the "P": network drive

    WriteExtFile ("P:\\Survey_Project\\BackupData\\DATA_BACKUP_"^Backup_Date^"_"^Backup_Time^".txt", Survey_Backup_Data)

    Of course, the size of the original text on the C: drive file will continue to grow because "AppendExtFile" is used to add the data of every investigation file in the data file (CSV, each record on its own line).  If the size of the file we will read again (ReadExtFile) will also continue to grow.

    Is there a limit to what we can read in and then write back?

    Thank you!

    My apologies, it has been a few years...

    CopyFile is a function that you can load the WinAPI.u32

    Once loaded, use it like this

    Success: = CopyFile (FileLocation ^ "Sourcefile.txt",)

    Destination ^ "DestinationFilename.txt") "

    Remember that you must include WinAPI.u32 with your packed files.

  • Old value of the element of text box

    I need to capture the old value of an element in a block because I need to insert it into a table of newspaper in my trigger for updating the post.

    For example, checkout_date. The block on the FORM for the update on the checkout_date; and the trigger for update post insert the entire record when the record is updated. However, I have a need to follow the last_checkout_date.

    So I created an element in the block (a placeholder if you want) which is invisible, called last_checkout_date. However, I know not how to fill out this point. I need a trigger? If so, I'll need the trigger when a user scrolls downwards or upwards.

    The example data:
    Name MEMBERID DESCRIPTION CHECKOUTDate
    ABC   123           Item ABC123  09/16/2011
    DEF   456           Item DEF456   09/22/2011
    ABC   123           Item ABC123  09/01/2011
    ...
    So when a query of the user for 123 MEMBERID, the user sees that 123 MEMBERID remove POINT ABC123 01/09/2011 and if he or she scrolls down, he or she will see the 16/09/2011. I need the last_checkout_date+ to follow checkoutdate* as long as the user scrolls vertically. And if she save the user stops to and updated, this is the date I want to capture.

    So using the example data, if the user scrolls to MEMBERID123 and POINT ABC123 and updates the record for 01/09/2011 to 23/09/2011; I would like to than the checkoutdate* to be inserted in the table of the newspaper as 23/09/2011 to checkoutdate* field and 01/09/2011 last_checkout_date+ field.

    How do I do that?

    Thank you

    You can use

    GET_ITEM_PROPERTY('LAST_CHECKOUT_DATE', DATABASE_VALUE);
    

    Another, in my solution best eyes would be to do this kind of logging into a database trigger, as it will capture all of the updates from all sources, not just forms-updates.

  • HP Jet 13-c002dx: the maximum size of the map of adapters support

    I'm sorry to repeat a question already asked the existing question was marked as "resolved", but has not answered the question.

    The question was: what is the maximum size of the microSD, supported by this device? The answer, in so many words, was, 'well, it really works with the adapters of 64 GB card. I have not tested with the 128 GB card, so I don't know. »

    The original question still received no reply, which was what is the maximum size supported. What is 64 GB? Or is this 128 GB? (And the limitations of size due to hardware, software, or both together? Format SDXC UHS-1 the so-called supports more 128 GB, even if perhaps not for micro size?)

    Best Buy could not find this information. I was not able to find a certain answer online either.

    I bought a map of UHS - 1 128 GB adapters and don't want to remove the package unless I know WITH CERTAINTY that the device will support it. Otherwise I'll lose $80 + $. At the moment, with her, sealed in the package, I can always take back and exchange it for a smaller card.

    Thanks for your help.

    I just, I couldn't believe that this little piece of information that is important has not been printed in the user's Guide. Worse still, no one seems to know the answer - not the Geek Squad at Best Buy (for which I pay), not here on the forum or in the HP Solutions guide. Finally, I appealed to someone higher in the chain (I won't say how, because I don't want their flooded of calls!), because it really was an oversight in the User Guide. Less than an hour, I received a phone call and was corrected thanks to a support person.

    Thank you, HP! I think that they won't really the extra mile to help me solve this problem.

    Therefore, the maximum size that this HP 13-c002dx stream will support 64 GB. I took the card of 128 GB unopened back to Best Buy today and I bought the 64 GB.

    (Advice to people looking for a computer/phone/Tablet Accessories: do your homework before shopping at Best Buy.) They will tell you anything to make the sale.)

    Please can you let me know what can be the maximum size of the address book.

    Thank you

    Hello Neev,

    There is no coded limit hard for contacts in address book to my knowledge. As long as the device has enough memory, you can add as many contacts as you like.

    Just keep in mind that you don't want to let yourself get too low for some reason any.

    Here's an article that might be of interest for the management of the memory of your device:

  • the maximum size of the data store in ESXi 4

    as I don't have a lot of space left on my data vmfs3 store, plans to add a 3 TB of HDD to the ESXi 4.1 Host. I will then use the new HDD for a creation of a new data store.

    I also want to ensure that the block size is the same as the existing data store.

    Please notify.

    Thank you.

    The maximum size of the LUN/disk in this case is 2 TB less 512 bytes (see KB VMware: ESX/ESXi 3.x/4.x hosts don't support 2 TB LUN for more details). The maximum size of virtual disk with a block size of 4 MB, please take a look at the article I mentioned in my previous post.

  • What is the maximum size of the image (in pixels) a height that supports the Muse? I noticed that if the photo is too high, reduce the Muses. Thank you

    What is the maximum size of the image (in pixels) a height that supports the Muse? I noticed that if the photo is too high, reduce the Muses.

    Thank you

    If you place an image with a height or width greater than 2048 pixels - in Muse - Muse will scale the image down proportionately, limiting the larger size to 2048.

    However, if you want to use the picture to its original size, you can move the image to the desired size by dragging handles to resize, or by entering values for height and width in the strip control on top. After that, go to the active panel and locate the image, then right-click on this image in the active panel and choose "import of large size. Which would bring the image lost the original image information.

    Hope that gives you clarity on what you wanted to know.

    See you soon,.

  • The maximum size of the Lun

    Hi people,

    What is the maximum size of the LUN vmfs3 and vmfs5?

    Just to add

    In VMFS 3, you may have a data to 64, but this store will be on does not include more than 2 TB.

    This means that you will use 32 2 TB LUN 1 data store. It is not recommended. 1 LUN. bulk loose any data store.

    Where with VMFS 5 you can creat a TB 64 logic unit number (if storage supports) and do a data store.

    Keep the best ratio of 1:1 = 1LUN per Datastore 1 practice

    For more information, see VMFS 3 vs. VMFS 5

    Please mark this thread as answered in the affirmative indeed.

  • Change the maximum size of the JVM heap to 1024 gives error

    Change the maximum size of the JVM heap to 1024 gives an error.

    Environment:

    CF9
    Windows 2003 R2 Sp2 operating systems
    XEON PROCESSOR
    RAM 2 GB

    After the installation of ColdFusion, one of the parameters that gets changed is:
    Server settings > Java and JVM > (MB) 1024 maximum JVM heap size
    ColdFusion Application service does not start with this setting. A file of errors is created in \ColdFusion9\runtime\bin\hs_err_pid1234.log (where 1234 number changes). The details of the log file are long so soon stick a sample.


    Arguments for the JAVA virtual machine are:
    Java.args =-Server-Xmx1024m - Dsun.io.useCanonCaches = false - XX: MaxPermSize = 192 m - XX: + UseParallelGC-Dcoldfusion.rootDir={application.home}/... /-Dcoldfusion.libPath={application.home}/... / lib - Dcoldfusion.classPath={application.home}//lib/updates, {application. Home} /... / lib {cation.home} / app... /Gateway/lib /, {application. Home} /... / wwwroot/Web-INF/Flex/Jars, {application. home} /... / wwwroot/Web-INF/cfform/Jars

    The JVM max 1024 m is one of the commonly recommended changes. Why change the maximum FMV of 512 m prevents ColdFusion from running?

    It is indeed a strange problem. Something does not seem right/normal.

    I did some digging and found a blog entry potentially useful:

    http://iamgoat.com/post/804922016/ColdFusion-application-server-wont-start-after-Windows

    It looks just like your problem, but it is true, it offers a quite specific problem/solution, that may not apply.

    Here's another question: are you looking in the \runtime\logs directory? The log files it may show more information on the problem, maybe before or after the time that develop these logs of PID? They may be secondary to another primary problem. Search specifically for the OutOfMemory string in the log files.

    If that can't find anything, I would suggest another thought: consider changing the JAVA virtual machine. I see you are using 1.6_0_14. There are several points between it and the last _21 you can try.

    Finally, a thought more to consider: since this is the Hotspot compiler which reports the error (SH in hs_err_pidnnnn.log), it is possible that the addition of a switch to turn off Hotspot, just to go beyond that, could give a different error message with perhaps more information. In the following (or the CF admin, if we in Standard mode or server), try to add - Xint.

    Let us know if any help.

  • Values in a dialog box application answering the multi-line text box field

    Hello

    When the user clicks on a radio button in my form a response request dialog box is displayed for the user to enter data.

    The value of the response dialog box is then added to a multiline text box.

    The script is on the mouse to the top of the radio button action and works fine the first time you click on the radio button.

    If the radio button is checked once again, the value of the response dialog box replaces the existing value in the multiline text box.

    What I need to do, is to have the response values show on a new line in the text box whenever you click on the option button.

    Can any advise please how to revise my script to work?

    Target for the field multiline text box

    var t = this.getField ("ActionAgenda");

    Response from dialog when the user clicks on the radio button

    var cResponse = app.response({)

    cQuestion: "enter your Action Agenda Item."

    ({CTitre: 'Action program'});

    Alert if you cancel

    If (cResponse == null) {}

    App.Alert ("Action point not will be not entered");

    Place the data in the dialog box in the target domain

    } else {}

    t.Valeur = cResponse;

    }

    Any help will be greatly appreciated.

    Thank you

    Change this line:

    To do this:
