Restrict for TextArea Component

hi,
im creating a calculator functionality in As3.0 here i'm
passing the number and also operator as a string to
TextArea by pressing the particular button like 1,2,3..+.../.
but i need to restrict the operator
here i'm using the restrict function for the Text Area
Component . if typed the number and operator in the TextArea
componenet instead of pressing the button it's working fine
Thanks
Sen

The restrict property (at least in as2, I assume its the same
in as3) only works as a typing restriction when the input textfield
(which is what a TextArea uses) has keyboard focus.
If you're assigning values by actionscript to your TextArea,
then the restrict property won't prevent you assigning values that
are 'restricted'. You need to do that with your actionscript so
that you only assign values that are 'permitted'.

Restriction for Material Component deletion after PO creation in PS

I want to restrict the material component deletion from the Projects once the PO is created for it. I have done the required configuration settings in OPSG (Change Profile Order Change management) where the system must give an error for material component deletion once the PO is created for it. But still it is not working.
1) Why the configuration in OPSG is not working?
2) Is it required to use user exit CNEX0009 or CNEX0039?
3) Where can I locate uset exit CNEX0039 if required?
Can anyone help on this issue!!!!

Hi,
Please check again the settings in OPSG.It is std functionality in SAP so i think it should work.

Hi All,
I wanna restrict user entry to certain no of lines in my
textarea component. Ho can i do this? I havent seen any relevant
API's for this in the help. Should i do this totally programatic
way?? Can anyone give me a hint?...
I can restrict characters and the requirement spec needs to
restrict lines too, say 16 lines.

Hi Kglad,
I have to restrict my textArea component to 16 lines. Even if
a single char is represented per line, it sould take only 16 lines
whatsoever.
I have restricted the no of chars to 572, which was there in
the requirement. Now i'm left with this probs.
Hope I can get it done..

How can i display image in mx:TextArea Component?

I found display img tag in htmlText of mx:TextArea component
is very difficult in Flex Air
I new a simple air project in flex builder, put the code
below in it, i put a glad.png file in the src folder, every thing
is OK, when i run it, image cannot be displayed. why this happend,
I search the google for the solution, it seems there is a bug in
air, and told me to use mx:HTML coponent, but that component still
can not display img tag.
could any one help me with this?
<mx:TextArea width="100%" height="100%">
<mx:htmlText>
<![CDATA[
<a href='
http://www.adobe.com'><img
src='glad.png'/></a>Click the image to go to the Adobe
home page.
]]>
</mx:htmlText>
</mx:TextArea>

I ran into a similar problem and wasn't able to find a way to have regular Flex components (like Text and TextArea) display <img> tags in their htmlText. Everything works find in a web-based Flex application, but once the same code was used in AIR, the images just wouldn't display.
I changed my display to use the mx:HTML component and everything worked fine (I was using only external images).

A few questions about using an XML file to add text into a TextArea component set as html

I'm using AS2 in Flash CS3.
I have a TextArea component in the stage that's loading its text from an XML and I've been able to use the ul and li tags to create lists. However, when I try to include a nested list it just inserts a line break between the nested list and the main list rather than indent it further. Is there a solution for this issue?
Failing that, how would I be able to add non-breaking spaces into the XML so they will render inside the TextArea component? I've tried and   without success. I scoured the net for some help with this and found some information about modifying the font embedding xml file with a new entry for the non-breaking space and that didn't work either, so that leaves me somewhat stumped.

flash doesn't handle nested lists (as you now know). you can work-around that limitation using css and creating your own indent styles. css have a marginLeft property you can use.

TextArea component AS3

I'm having trouble both working out or finding out how to
apply an imported css file to the CS3 TextArea component. I've
frequently done this in AS2 using Flash 8, but that code no longer
works. If anyone knows could you please let me know. Here's the AS2
code I've used previously:
private function loadCss(){
var myStyle = new TextField.StyleSheet();
myStyle.load(this.CssPath+".css"); // the CssPath variable
here was supplied within an object passed through to the
constructor
textArea.styleSheet = myStyle;
loadXml();
}

Thank you Anirudh,
I have been using the TextArea component because it has code to handle scrollbars, and in Flash this component is a wrapper for a TextField object. As far as I can see this is not the case in Flex, and my AS3 code sets almost all of the TextField attributes, so I probably can't use Flex and the Flash Builder anyway. At least not without throwing all my code away.
Besides, the .swf file generated seems to be much bigger than in Flash.

Single batch for a component in production order goods issue

Hi,
We have a requirement where during good issue to a production order
through CO11 & MIGO, more than one batch of a particular component
should not be issued i.e. only one batch for a component should be used
for goods issue for a production order..If the stock for a particular
batch not full it should not allow the system to issue that batch. We
want an error message or any other restriction where system will not
allow more than one batch for a particular componet to a production
order.
Please advise how to design such scenario.
Regards,
Chandan

Hi Chandan,
Try with below steps,
- Create Batch Search procedure -
- Create Batch Determination Strategy for that Material (Create it for both COB1 and MBC1)
- Set NO. of Batch Split as 1 and don't tick Check box for Change Allowed
- Then go to Order type Dependent Paramter OPL8 - Assign your Batch Search Procedure and also tick Check Batch (This will check the auto check if Batch Determination is done manually and if you have violet the Batch Determination it will throw an error Massage)

Formatting Tags appearing in TextArea Component

I'm having an issue with TextFormat tags that are appearing
in textfields. Here's an overview of what I'm doing:
Basically, I'm trying to grab the text from a textArea
component: (myText = myTextArea.text")
Because I want to retain formatting, I have the textArea set
to be html.
Thus, myText becomes the text you see below
So the myText data is then stored in XML, but later when I
try to access it, it fills that same textArea component with the
literal code rather than the formatted text. How do I take that
TextFormat string and convert it back to it's original form? I've
tried myTextArea.htmlText but I guess that isn't it. Thanks for the
help!
Thanks!

Let me make my question easier to understand: ;-)
I've got the text formatting (below) in a string. Using that
string, how do I display the text it contains correctly?
Thanks!

Thank you Krys for your tip, but as you can see thrue this link www.pccruzadas.com when you type a message I don't want you to go for the top of the page, I want you to remain in the tesArea and see the message I put there after you click the button. Sory for my English.

TextArea component scrollpolicy being ignored

The scroll policy for the textArea component appears to be "auto", and that works just fine.
However, I want to be able to turn it off in certain situations, i.e., not have the scroll bar appear.
I do the following which I thought would turn it off but the scroll bar still shows up.
Any help would be appreciated.
Code Snippet:
     myTF = new TextFormat("Arial", 10, 0xFFFFFF,false);
     myText_mc.myTextArea.setStyle("textFormat", myTF);
     myText_mc.myTextArea.verticalScrollPolicy = "OFF";
     myText_mc.myTextArea.horizontalScrollPolicy = "OFF";
Thanks,
Vivian

should be all lower case
myText_mc.myTextArea.verticalScrollPolicy = "off";

TextArea component issue

I have used a TextArea component, and for unknown reasons the
space bar
on the keyboard does not work when entering text once it is
published.
There is no additional actionscript being used outside the
defaults.
Anyone ever had this happen to them? Thanks.

ActionScript file using TextArea component

I have been developing applications in Flash CS5, but I coudn't stand the completely useless code editor any more, so I have installed the Flash Builder instead.
The problem I'm having now, is that I have an AS3 class that uses the TextArea component. But if I make an ActionScript project, I cannot import the TextArea class as FB doesn't seem to know about it. And I know nothing about Flex, so if I make a Flex project, I have no idea of how to combine my AS3 class with the TextArea component.
I am amazed - I thought that would be ridiculously simple, but I have been browsing Adobes sites for days now, and I'm not an inch closer to any solution.
Anyone knows something to help me?

Dynamic linking within TextArea component

how can i include an MC or button inline within the HTML text
of a TextArea component -- and also have that object link to an AS
function? i want to have icons within the text of my TextArea that
open pop-up windows within the Flash application (MC linkage).
is this possible?
is asfunction used? if so how?

Well if you are still interested in using a text component
instead of a Button the way you would go about this is using
textWidth. Here's how I've done it before using a text / label
whatever you want that shows text.
// => Set our text we got from database
myText.text = "This is the text I got from the DB";
// => Validate it so that way we make sure we get right
numbers
myText.validateNow();
// => Find out how wide our text really is.
var textWidth:Number = myText.textWidth
// => Reset the width of our text component and add 20 for
a little buffer
myText.width = textWidth + 20;
Now my suggestion is if your going to be dynamically creating
these on the fly from a database call you throw it into a method /
class and have that do all the work for you so all you have to do
is pass the text to it and it resizes itself based on the example
above.
