Text box for data entry

Hi guys,.

I have a few areas of data entry in my GUI that I control.

The data are entered in hexadecimal format, IE. Ox is sitting next to the text entry box and the user must enter a value between 00 and FF for a single byte.

As soon as the user tries to enter R eg I want for a warning sound to happen and him should not be accepted by the text entry area, I also want to limit the size of a byte, that is, a person may enter FFF.

Any help much appreciated.

Use a digital control.  Change the properties to:

Appearance: See the Radix

DataType: U8

Display format: hexadecimal.

  • Default value is evident in textbox for data entry

    Hello everyone.  I am building a form of contract farming for a customer.  Here is a picture of high level of form for discussion:

    Operating agreement (object label for the title of the form)

    By signing this document, you agree to all of the language indicated on the following pages. etc. etc. etc. (label object for the static text)

    Name of the customer (text object for data entry)

    Address (text object for data entry)

    City (text object for data entry)

    State (text object for data entry)

    Article 1 - this agreement is between the customer, as indicated above and the company providing, etc. etc. etc. (object label of static text)

    Question 1

    By the request of the customer, I removed the label from the name text box of the Client (as well as all the other text boxes).  Want me to set the default value of this to say 'Customer name' indicating that the customer name text box must be typed here.  I've added the phrase name of the customer to bristle reversal as well help.  So we do not weigh those filling out the form, I added a line of JavaScript on the Enter event , so the default text in this text box is removed when the user clicks the text box to enter data.  The code I used is: this.rawvalue = "";  

    This solution works very well because we do not want those filling in the form of having to select and delete the default of 'Customer name' when they want to enter data.  Thus, with the JavaScript in place by default is removed after clicking in the textbox control.  The only problem I have with this solution is that if a person would click in this text box after entering the data or tabs in the text box after you enter the data, the data that has been entered is deleted (for the code).  Does anyone know how to set a default value that clears when the user enters in the text box for entering data, but does not erase what the user types in if they want to add to the data they entered or accidentally click in the text box.

    I thought to make the textbox to read after a user of other data and leaves the text box BUT if they want to change what they got they can't because it is read-only.

    Any thoughts on a solution that would meet my needs?  I prefer not to have a button on the form that a user clicks to erase the contect of a specific text box, but it's the only other thing I can think of that would work.

    Question 2

    For label objects as Article 1, I need to add a large amount of data (more than 1 page of text in the paragraph format) in a label/text box.  I suppose that the best object to copy and paste this data into is a label and not a text box (which I could remove the formatting and reading only).  My one major requirement for this is that I develop text fields before this Article 1, which should push (wrap) Article 1 contained on a second or third page.  I can set the property object to break up, but I don't know if that will lead the content of Article 1 partly wrap to a second page.  It will be (is that the right solution)?  I prefer not to enter this long content of many objects of label for each paragraph, but I did it in the past and it works.

    If it's important, my design of the shape has a subform (with the property set to cast) and each object embedded in this subform in the hierarchy list (additional subforms, text boxes, labels).  I implement it effectively and function I wanted me?  I know it's hard to image.

    Thank you all for reading my post and I expect all your comments and suggestions.

    Jeff

    Hi Jeff,

    Here is an example, where the textfield object has a null type. This allows to have the legend inside the textfield object. As soon as the user clicks inside the textfield object, the 'legend' disappears and the textfield object is available for the user to type in.

    https://Acrobat.com/#d=uqcNdyoPayTa2MbPb8F88A

    The form has two options. The second replicates the 'legend' at the end in parentheses if the field is NOT null.

    I will come back to q2 after a bite... Army market on her belly

    Hi all

    A sorry again, I am very new to forms and have another question. I have a drop down list which list by selecting certain values I need an another field will not be available if the user can enter data.

    Hopefully this example is logical:

    If someone could give me some examples that would be a great help.

    Thank you very much

    Here is a script that you can use for the validation script custom from the drop-down list. It resets the value of the text box, whenever a change is made to the drop-down list. You can get rid of the line doing it, if you do not want to. Change "text1" in the code to match the name of a text field that you are using.

    Validate a custom for picklist script

    (function () {}

    Get the selected value

    v var = event.value;

    Set up an object to associate status items text box read-only

    var f_state = {}

    'Outside': true,

    'Back': true,

    'Interiors': true,

    'Cotton': false,

    'Wool': false

    };

    Get a reference to the text field

    var f = getField ("text1");

    Clear the text field

    f.Value = "";

    Set the State of read-only text box based on what is selected

    If (v f_state) {}

    f.ReadOnly = f_state [v];

    }

    })();

  • Elements that cannot be used for data entry

    Is it possible to do an article (P2008_COMMENT), which is of the type DISPLAY AS TEXT (not FACT NO STATE to SAVE) work with a show_and_hide function?

    I ask, because P2008_COMMENT would not work as this type of item, but if I changed the type of text element, it would work with the show_and_hide function. However, then I'm done with an empty text box ready for entry. All I wanted was a comment.

    Thank you

    Try changing type P2008_COMMENT - display text (saves the State). Choose the item type and use the works of function $x_HideItemRow('Item') for me

  • Cannot type in any text box for a specific Web site

    Hello

    I have a site and I can't type anything whether in any textbox (search box, for example) when you use FireFox. I tried the site safe without the effect of loading Mode, I can not type anything.

    I've seen similar behavior, but it always seems to get it fixed by disabling modules while in my case is not.

    I checked out the site on Windows, Mac and Linux, in all, it's the same behavior if you are using FireFox. With all other browsers, the site is very good and I can type in these text boxes.

    Let me know if this has happened to someone else, I am trying to settle this problem because it's really annoying for readers.

    Thanks in advance!

    I see the same thing on this web page.

    It seems that some JavaScript on this page is not working properly and therefore does not select the input field or text box when you click it.


    I can achieve input field by pressing the Tab key until I get a slider, so you can use it as a workaround for now.

    You can contact the site and inform them that their site does not work in Firefox.

  • Substituing a text box for a check box

    I have a PDF form that has been transformed by Adobe in a form to fill out. The only thing is that he has converted some boxes in an area of free writing whereas I want him as a checkbox.

    It seems that the only way I can do this is to insert this box on the current free writing area and its annoying and time consuming.

    Is it possible that I can replace just the free writing for a checkbox area without having to change the size or shape of the box?

    I remove the field from the text box and add then checkboxes or a checkbox field, if they are part of an exclusion group.

    The Assistant shape is poor enough to create form fields. I just create them all manually by using tools such as creating multiple copies as needed.

  • Change the background color of the text box for the required field

    Guys,

    I want to change the background color of textfield required when the user is in data entry Mode. And when the record is validated successfully the background color should be back to the default.

    That's what I've done so far.

    Created a Visual attribute that contains the background color.

    In the record of the creation of the data block added the code below.

    IF: SYSTEM. BLOCK_STATUS = 'NEW' THEN

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) BATCH ', VISUAL_ATTRIBUTE, 'ENABLE_COLOR');

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) VENDOR', VISUAL_ATTRIBUTE, 'ENABLE_COLOR');

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) AMOUNT ', VISUAL_ATTRIBUTE, 'ENABLE_COLOR');

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) ACCOUNTING_DATE', VISUAL_ATTRIBUTE, 'ENABLE_COLOR');

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) INVOICE_DATE', VISUAL_ATTRIBUTE, 'ENABLE_COLOR');

    ON THE OTHER

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) BATCH ', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) VENDOR', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) AMOUNT ', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) ACCOUNTING_DATE', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) INVOICE_DATE', VISUAL_ATTRIBUTE, ");

    END IF;


    And in the key to commit the following code is added

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) BATCH ', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) VENDOR', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) AMOUNT ', VISUAL_ATTRIBUTE, ");

    SET_ITEM_PROPERTY ('MASTER_APM_INVOICE.) ACCOUNTING_DATE', VISUAL_ATTRIBUTE, ");

  • Text box for the title of master InDesign

    I want the positions and areas of text paragraph styles used on slide masters to stay the same on every page, regardless of the text in the box. As much as I know InD does not? Let me explain. I don't think I use InD commonly used. I use it as a more robust PowerPoint (MS Paint do you think vs Photoshop). I use it for the graphical flexibility and I use A LOT of HAVE graphics and make interactive PDF presentations, etc. My biggest beast with InD is with page titles. Imagine a title on each page, which all have the same paragraph style and specific location. Every page has unique text for the title, but I want the paragraph styles and positions remain the same, or better yet, to update the need later via a master page. Sometimes our presentations will be worked on my many people. Because as they put some text in the text block and tile, they override the master page text frame and where are allowed to move inadvertently. When all the sections back together the titles of the pages are free to bounce around page to page; albeit very subtly. With a terrace of more than 100 pages, it takes a significant amount of time to readjust all the titles of the page again. Which in my mind is an important aspect to have masters in total.

    The best work around is to use chapter markers. And they work great until the needs of title, a jump of line and then everything goes to poop because line breaks allow no chapter markers...

    I wish there was a way to break the master text block substitutions while keeping format constraints. It is the ONLY of PowerPoint feature I've wanted that ind did. If anyone has a clever work around or better understand, I would be grateful.

    Master frameworks should work properly. You can pre style and lock them to position, and then change the application preferences to allow selection of locked objects.

  • Restrict the text element of data entry

    Dear comrades,

    I have a block of data. In this block, I have a DB text element. When I use the execute_query, the values are filled in this point of the DB block text. Some of the text elements are filled with value and some are not according to the database table.

    In this situation, I want to limit this element of text in a way so that if it already has the data, so no one can change the value other than (i.e. If the text element has a null value) the user can put data out there.

    Please help me this app. Thank you for your support and your help.

    per block of several recording, you need to use SET_ITEM_INSTANCE_PROPERTY instead of set_item_property, but in this case, only the INSERT_ALLOWED AND UPDATE_ALLOWED properties can be set. see the forms for more information online help

     set_item_instance_property('myblock.myitem',current_record, insert_allowed, property_false);
     set_item_instance_property('myblock.myitem',current_record, update_allowed, property_false);
