How can I check if a field is empty? The code that I think that a '0' is empty, what is wrong.

The code I used is copied from this thread: https://forums.adobe.com/thread/1223607

I created a button that lists each field if it's empty. However, a field will always pop up even if there is a character in it, i.e. '0 '.

Help, please.

I expected that you would change the code based on what I've shown. Then change a line to:

If ((f.type == "text" && f.valueAsString === "") |) (f.type == "checkbox" && f.value === "Off")) emptyFields.push (f.name);

    How can I check to see if I have the latest version of Windows XP? If I don't have the latest version of XP, how can I install it?

    There is not "later" version of XP - XP there and there is that Service Packs added to it.

    To know what Service Pack level you are to start - run and type in "winver" (without the quotes)

    Also, it would be nice if designated so help file functions have been supported in real time or now.

  • How can I check replacement memory is correct for the following laptop:

    I'm considering a purchase in the next 2 months of this device: HP ProBook 4530 s (XU016UT #ABA).  Is there a list indicating the memory that is compatible with this unit of the brand and model?  I'm looking at this particular unit: Corsair Memory - 8 GB (2 x 4 GB) DDR3 SODIMM Memory (CMSO8GX3M2A1333C9 The 4530 comes with Win 7 Pro 32 bit OS, so it will use more than 4 GB of memory.)  Thanks for any help you can offer.  Jim.

    Hi, Jim:

    This memory should work, but only 4 GB will be usable with a 32-bit operating system. You need a 64-bit operating system to take advantage of more than 4 GB of memory.

    When you receive your laptop, call HP at this number below and see if they will send you a W7 Pro 64 bit game of fast laptop restore disks and if you decide to install 8 GB of memory, you can install the 64-bit operating system.  You will need the model number and serial number handy.

    1-800-334-5144

    You can use almost no portable PC3-1333 ECC memory.

    This memory will work:

  • Can you create a text field entered by the user that the content of the flow in a subform?

    I'm working on a project to convert into a document library of more than 600 forms from Word to PDF, most of the time it's simple and binding the fields to the database schema and use subforms works very well - however, there are some cases where there is a combination of input fields by the user mixed with fields of database and in some cases , the fields in the end user are all there, but the amount of content can vary from 250 characters to thousands.  The project manager wants a PDF that allows users to enter any amount of text they should and have the function of shaping the way it is as if all the fields have been populated by the database - I don't know of a way to make that work only if the content is first registered in the schema (or implement CM and have all users working in LiveCycle, but the basic data use PDF, take her is not an option right now).

    If anyone has any ideas how to operate the these things I would be very happy to hear about.

    Thank you very much

    Hello

    If you can post your form in the post, I can have a look and give my comments.

    I created a sample file for your reference...

    (1) Flowed is set to the content property for Page1.

    (2) each text box is placed inside a subform that is also a property content value Flowed.

    (3) in the properties of the form, as the default tab, set the format of PDF rendering dynamic XML form.

    (4) in the properties of the form, on the overview tab, specify the Type of Preview as "Interactive form" and preview XML Adobe as a 'dynamic XML form' form. (this step is to preview the PDF file in the Designer).

    (5) to save the form as dynamic XML form. (File-> Menu save under).

    I hope this helps.

    If you have any questions, please post your form...

    Thank you

  • How can I get Thunderbird for me to choose the SMTP that IMAP when reinstalling after a system crash?

    I had a crash of the system Jan. After the crash recovery (Windows had written on some parts of the disc but recovered most of the things, however, they were put to the States as if they had just been installed), Thunderbird did something I've been unhappy with & I reinstalled it. When I did it I did not select IPOP or IMAP but come with IMAP, I had never used before and knew nothing of. However, now after reading about IMAP & have consumed with Comcast, I don't like it intensely - it is slow and cumbersome and cannot me save emails with all the parts for them permanently. I did have the time to continue so far. How can I return to the use of IPOP?

    POP and IMAP are the two inbound messaging protocols.
    SMTP is the outgoing mail protocol.

    Maybe when Apple invents its own protocol of e-mail it will be iPOP as all other iSomethings

    Here are the instructions for switching to Thunderbird from IMAP to pop...

  • How can I check my membershp on line on the Web Adobe Creative Cloud site?

    I've called customer service, but they were unable to help me because they said that I need very good internet connection, I have only my internet flat and my internet schools and I got the same problem every time, so I know this isn't the problem. Whenever I opened one of my software like illustrator, he told me that I had a few days to connect to my membership, I would be online, connect to the adobe Web site and making sure she is not found. Now after calling the support system, he said only: I have connection problems and I can't access anything, or see my online subscription.

  • Question: How can I format a DVD to use on the computer that they had already been used on a DVD recorder to disc progs TV one

    Hello.. Can someone help please, I have a lot of DVD + RW and DVD - RW Traoré were used to record TV programs... and the DVD recorder to initialize before use when I try to use them on my drives it dose does not format and they need to be formatted re I do not know how... Help please John Cheers

    Hi John;

    What format are the programs being recorded in? Your medial player is probably missing the right codec. Usually, when this happens, you will get a pop up window in which Windows give the possibility to provide web support. If you click web support, a page opens that gives you the file format.

  • How can I set up an automatic reply to the messages that I can not answer because I'm missing?

    Don't want incoming when I am out of the country, reloaded emails on my blackberry for each incoming e-mail.  So with an atomatic answer that I can not answer would help that shoot.

    I don't see what that has to do with Vista can I or WIndows mail.  Usually, go you to your mailbox, which is located on a server, not on your PC, directly from the Blackberry.  I don't know anyway to have an automated response to messages that arrive in your Inbox on the server side and it is likely that your Blackberry will see little matter what type of response automated you have.  If I was faced with this situation, I would create a Google Mail account, set up my original (server side) account for messages automatically transfer to the gmail account and ignore gmail until my back account.  You can have your original mailbox to send an automatic response, if you want to, because it transmits incoming messages to other mailboxes mailbox.  Your Blackberry should not see the outgoing messages from the server.

    On the Toshiba driver European page you will always find the number pilot s versions and you can compare it with the s version of the driver installed on your laptop.

    But just a hint; If your laptop works without problem, then I would not change anything in the operating system. I'm always that notice; never change a running system ;)
