Is there any way to forse user to put at least 5 characters when using LOV?

Hi gurus,
I have a question.
Is there any way to force user to put at least 5 characters when using LOV?
I want user to put at least 4 characters before/when using LOV.
Is there any way to do that?
Thank you for your answers.

Hello,
i've tested it both on 6i and 10g and also set the lov name at runtime.
All i can say is, it does what it is supposed to do.
So you should give it one more try:
- leave the item properties NULL ( LOV name ) and NO ( Validate_From_List )
- add following code in the WVI - Trigger
IF :AUFTRAG_NEU.PN IS NOT NULL AND LENGTH ( :AUFTRAG_NEU.PN ) < 5 THEN
  Show_Message ( 'Bitte 5 Zeichen eingeben' );
  RAISE FORM_TRIGGER_FAILURE;
ELSIF :AUFTRAG_NEU.PN IS NULL THEN
  NULL;
ELSE
  SET_ITEM_PROPERTY ( 'AUFTRAG_NEU.PN', LOV_NAME, 'LOV_PN_PROJEKT' );
  SET_ITEM_PROPERTY ( 'AUFTRAG_NEU.PN', VALIDATE_FROM_LIST, PROPERTY_TRUE );
  IF SHOW_LOV THEN
    NULL;
  END IF;
  SET_ITEM_PROPERTY ( 'AUFTRAG_NEU.PN', VALIDATE_FROM_LIST, PROPERTY_FALSE );
  SET_ITEM_PROPERTY ( 'AUFTRAG_NEU.PN', LOV_NAME, '' );By the way, what exactly doesn't work?

  • Is there any way to force the applet to load the file without using cache?

    Hi,
    I have the applet that renders some data from a file specified as the parameter. The problem is that the user can do something, that changes the input file and reloads the page, but the applet renders old data (from browser cache most probably)
    Is there any way to force the applet to load the file without using cache?

    The initial view (IV) settings within a PDF file are static tags - they can't be made to dynamically-adapt based on the window dimensions,it's the renderer (Acrobat, Reader, or whatever else is opening the file) that decides if and how it will follow the IV requested by the file header.
    It would be possible to use a Page Open action on the first page of the file, which does some nasty math with the various doc.*WindowRect objects to work out how much "wasted" space there is, and then set the doc.layout and doc.zoomType properties - but page actions are a different concept to IV as the zoom will reset itself every time that page is viewed. Users don't like their application apparently fiddling with the zoom level without being told to!

  • Is there any way to prevent the OS from querying the Superdrive when start

    Just a random question. Whenever my MacBook Pro starts up (either from sleep or a complete/fresh start, the OS queries the drive slot to see if there is a disc present. While this may be normal behavior, it seems to slow down the start up process. (I rarely ever have a disc in the drive). Just curious if this, in fact, normal, or if there's something awry.

    No

    How can you tell? Based on the noise it makes?

    I can think of two possible stumbling blocks:
    What are your 8.6 options for "byte order" and "prepend array or string size"?
    Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

  • I reinstalled windows on my computer, wiped out everything is there any way to retrieve my library or at least my purchases, I reinstalled windows on my computer, wiped out everything is there any way to retrieve my library or at least my purchases

    I reinstalled windows  and wiped out everything. Is there any way to retrieve my library or at least my purchases??

    It has always been very basic to always maintain a backup copy of your computer.
    Certainly you did not reinstall you os without making sure your backup copy was up to date.
    Just use your backup copy to put everything back.
    If for some reason you failed to backup ( not good), then you can transfer itunes purchases from an ipod:  File>transfer Purchases.
    If you are in the U.S, then you can use the newly released Beta version of icloud to retrieve them.  open itunes store, click Purchased under Quick Links.
    ALWAYS maintaining a backup is very important.

    Here is some guidance ...  What to do if your iOS device is lost or stolen
    And some more ...              Reporting a lost or stolen Apple product
    Remember, take a note of the incident number when you have reported it to the police ... without that, any domestic insurance claim will not receive attention.

  • My iphone is stolen .. is there any way to know the numbe of the person going to use in the future .. I have the serial no. and every thing .. and it is registered under my name and my information with iTunes ??

    my iphone is stolen .. is there any way to know the numbe of the person going to use in the future .. I have the serial no. and every thing .. and it is registered under my name and my information with iTunes ??

    If you had find my iphone activated on the iphone itself before it was stolen, then you may be able to track it.
    Otherwise, there is nothing you can do.
    Sorry.
    Report it to the police and your wireless carrier and change your password.

  • Is there any way to change user operations on multiple tracks at once?

    I have a complex project (99 tracks, dozens of menus and scripts). I need to make one version of this DVD for the end client (teenagers at health clinics) who will be forced to view it in a specified way, and another version for educators (staff at the clinics) who will be allowed to fast-forward and have access to a menu from which they can jump to different points in the DVD.
    I have different menus to serve as "first play" for these different versions so that I can easily switch between versions when burning disc images, and I have set up GPRMs to make navigation different for the two versions automatically. My problem now is that I want to disable forward scan, next program, root menu, and title menu for the client version. As far as I can tell, I have to do that independently for every single track and menu. Bleah. This is especially annoying since the DVD is still in development, so I am continuing to change small things and will need to keep both versions up to date as I do.
    Is there any way to select multiple tracks/menus and change user operations on all of them? Or any other work-around or script that could do it? I thought this would be a perfect task for the automator, but I'm not very familiar with that application and don't know how (or if it's possible) to create new actions other than the ones that are available.
    Any ideas?
    thanks!
    Julie

    Thanks. But the disc inspector only appears to let me change things like where the title menu button takes you, not detailed user operations. I have pretty much given up on this being anything other than a giant hassle, but if anybody knows whether a script could do this, I would be eternally grateful.

  • Is there any way that I can delete photos from my iPhone by using my Mac?

    Is there any way that I can delete photos from my iPhone 4s by using iPhoto on my iMac (Mid 2011) using OS X Yosemite v10.10.2?  It seems it would be much more convenient to use my iMac to delete the photos from my iPhone or iPad, but I can't figure out how to do it.  Thanks for your consideration and help!

  • Iphone 4S newly updated to iOS8, keeps popping up window notifying me of things I turned off (cell usage, location, etc) to preserve battery life.  Is there any way to make them stop telling me every time I use the affected apps?

    I have finally taken the step of updating my iPhone 4S to iOS8 after learning the hard way last update to wait for the bugs to be worked out.  I was horrified to find that the battery was being sucked dry in no time at all.  After finding a great article posted elsewhere on the apple forums, I went through and turned off all unnecessary options involving the use of cell data, location services and background refreshing.  My battery life has thankfully returned to what it was before the update.  
    HOWEVER, now, every time I open an app for which I turned these things off, the window informing me of that pops up.   I am getting really irritated by this as I made all of these decisions deliberately and am well aware that I may need to go back and change them in order to activate certain capabilities when I want to use them.  I had done the same thing with the last iOS, but there were far fewer that needed to be turned off and the battery life seemed to be less affected by those that I left on so it was not the annoyance it has become now.
    Is there any way to make the phone stop presenting me with these idiot messages?   TIA

    Sorry no, there isn't a way to turn off those reminders.

  • Is there any way to prevent my SSIS Tasks from reformatting themselves when I want to change the Name

    So all my tasks are nicely laid out in my SSIS Package. Now I want to go add a blurb to the Name to make it a little more descriptive. When I do that, Microsoft Visual Studio just automatically re-sizes the task so the entire description, name fits. When
    I make it the right size, my scripting name is wrapping and that's the way I want it to look within my Package. Is there any way to stop Microsoft Visual Studio from automagically adjusting the size of my task when I click on the Name to edit?
    Thanks for your review and am hopeful for a reply.

    There is no way. The designer canvas received improvements in SSIS ver 2012, but this specific aspect remain unchanged.
    What I do I simply use the Format -> Autolayout -> Diagram or you can also/instead Ctrl-A to select all and choose "make same size"
