How to set the input to a text field filter?
I use a text entry (a flash component) to which the user will enter numbers only in (positiv and negative integers and floating point numbers) but not any other symbol.
Copy the following code
on keyDown me
If ("1234567890 -") contains the key or the key = backSpace or key = tab keyCode = 123 or the keyCode 124 = then
Pass
on the other
stopEvent
end if
end
This script works fine when I use it with style text old fields to the Director. It does however not work with new component flash style (text entry).
How can this be repaired?
Thanks in advance for any help.
HUMAN RESOURCES
First of all, I should mention that I have avoid using Flash inside Director, so there may be a better way.
As you noted, catch events keyDown globally affect all entrances to the keyboard. If you want to specify a subset of sprites so you need a management system which. The simplest would be a global list that fill you it with a small number of sprite when switching to a new framework.
global gRestrictedInputSprites
on preparemovie
gRestrictedInputSprites = [1, 5, 6, 23] - SAMPLES
keyDownScript = "chatchKeys()".
end
on stopMovie
keyDownScript = «»
end
on chatchKeys
If gRestrictedInputSprites.getPos (_movie.keyboardFocusSprite) then
If _key.key = "," and then
stopEvent()
on the other
Pass
end if
on the other - overall restrictions on entry
Pass
end if
end chatchKey
And then add a beginsprite to your Framescript to set the values of the gRestrictedInputSprites for each image tag loop you on--assuming that you place the frame head with "go the frame."
global gRestrictedInputSprites
on beginSprite me
gRestrictedInputSprites = [] - the list of sprites all entry who need entry restrictions for this frame.
end
on exitFrame me
go part
end
If you follow this path then I suggest to use a GPDL to set the sprite shortlists. No need to write more than one behavior.

How to set the vertical alignment of text in a table style
I hope I'm missing something easy. I know how vertically and horizontally align text in a table cell.
What I would do, is to be able to do as well in a style - section, object or character, it doesn't matter - so I don't have to do it manually to each cell in a table. I can't figure out how to put this in a style. Is it possible to do this?
Thank you
Marcy
You create a cell Style. In a cell Style, you can set the vertical Justification on the text panel.

How to limit the length of a text field in a dialog box (ADM)
Hi all
I need to limit the length of a field in a dialog box (ADM) edit_text, but char_limit doesn't seem to work, it's my code the problem ?
{
char_width: 8.
height: 100,.
item_id: 'Rete ',.
type: 'edit_text. "
Multiline: true,
char_limit: 5.
Width: 500,
}If not, maybe I can use events to do the same thing with the onKeyStroke event but I don't know how to use the event in a dialog box (ADM) or if it is still possible...
Any idea?
Thank you for your help.
Phil
There are two events that can be used to check the length of the text,
The first is the action event for the text field, which is called when the field loses focus, it is a member of the purpose of dialogue with the same name as the item_id. This event could also be used to update another field in the dialog box that indicates the number of characters, you may even have a small picture of alert which becomes visible to make it obvious that there is a problem.
The other event, as already mentioned, is the validate event. This allows to block the exit from the dialog box and display a popup to alert to the user.
You will find some examples of dialogs here:
http://www.pdfscripting.com/public/65.cfm
Take a look at the pages resize tool dialog box. It will give you some ideas of what can be done.
There is a plug-in Acrobat for creating dialogs here:

How to set the input frequency output rate linearizer function
I have an input range of 0 to 2000 Hz with a digital meter. I need to convert the signal in gallons per minute (GPM) using a non-linear process with 10 points on the scale. Here are the 10 points of the scale.
In display
0 =.64 Hz DSP0 INP = 0.001 gal/MIN
INP 1 =.83 Hz DSP1 = 0.002 gal/MIN
INP 2 = 0.03 Hz DSP2 = 0.007 gpm
INP 3 = 0.83 Hz DSP3 = 0.025 gpm
INP 4 = 0.12 Hz DSP4 = 0.038 gpm
INP 5 = 01.16 Hz DSP5 = 0,126 gpm
INP 6 = 07.77 Hz DSP6 = 0,380 gpm
INP 7 = Hz DSP7 = 0.503 02.43 gpm
INP 8 = 016.33 Hz DSP8 = 0.637 gpm
INP 9 = 695,22 Hz DSP9 = 1.056 gpm
I need Labview to provide a linear display throughout each segment (i.e. between the sequential characteristic points) so that any entry in the system in Hz translates into a rate of GPM. Any ideas?
Thank you
Toddzilla
This VI works perfectly now. I had to increase the samples per second at 80 k so he could flatten. The function ' scaling and mapping ' is the key to this.
Be sure to enter at least 20 frequency of entry on the front block until you try to run it, increase intake of up to 1700 freq for GPM indicator work...
Thank you all for taking the time to help me.
Kind regards

How to capture the input value of text by the user in a popup page search LOV?
I need to capture the user entry in the LOV search page. I added a controller in the LOV region, and the speed is also work, but I have to hold the entry to search for in the contextual search page. Also do you know what the text entry id "keyword"? then I can try store the value in LICS of the Commander.
Hello
Why do you need to write code in LICS?
You have the user type field in your query of Lov VO (then only you had created search are they allowed in Lov research/item of type user), I proposed is just changes to sql to check if the user type is vendor and caters fields null., something like below for each address field:
, DECODE (user_type, "PROVIDER", NULL,
) address_field1 You should always share full details, including related sql code and xml on your question to avoid all these discussions back
Kind regards

How to display the box around a text field read-only - Jdev 11.1.2
Hello:
In an ADF Web application:
I have an af:inputText field, but I want to say read-only. So I put the readonly = true property, but when I did I lost the video box around the field. How can I make the text read field only but keep the box around the text display? I also tried setting to off but then it displays in gray. Is it possible to have the look of text just like a field of regular text input field but make unmodifiable?
Thanks for the help.Hello
I think that you should use the disabled property and with skinning, change the color of what you want.
For example:
af|inputText:disabled::content { background-color: White; font-size: 10px; font-family: Verdana, Arial, Helvetica, sans-serif; font-weight: bold; color: #000000; }
Kind regards

How to drive the content of a text field or table from a drop-down list selection cell?
Users will choose an option in a menu drop-down. I want their selection to control the contents of the cells in a table or text elsewhere on the form fields.
For example, 'The coldest season of the year' by selecting 'winter' in the menu drop-down displays in a table cell.
Thanks in advance for the help.

Hi Nick,
Here are some examples:

https://Acrobat.com/#d=20lQl9JfL19aBtbPC1WYbw
https://Acrobat.com/#d=Hi0ZwVgVB1PWbxc6OJ0z4A
If you open these in LC Designer, you can view the script by selecting the menu drop down and looking at the script at the top of the window Editor. If the script editor is a single line, you can drag the lower edge to make it bigger.
Good luck

set the input value using a workflow setting?
Jdev 11... 2
I have a taskflow browse master / detail that called the edict taskflow passing parameters to a router that will either modify it or create method for the detail record (change/create master is in a different position). I can successfully modify/create the main form and I can change/create the detailed form, but I didn't understand how to set the input value for the agency_Id (of the master) in detail. I control data binding to create my detail record 'create', and I have a task flow parameter that has the agency_id I want as the default value in the detail. I don't know where to put the input value. I tried to add another method to the method call that has her 'create' binding for retail, but it seems that I can have only a single method. Do I need another method call to set it? Or should I do something programmatically? (I'm Javaless, so hopefully I can do declaratively).
Thanks much for any help. If I can figure out how to make this piece, I'll have the beginning of an application that does something useful.
LBHello
There is a new Createmethos called 'create with Params' that you can use for this.

Simply plug the parameter to the variable of pageFlowScope containing the input parameter
