Setting scroll bar to inbisible when not needed

Question

Here is the post again, some quotation marks came out as
letters before. This is correct version
I'm using AS 2.0, and have added a
scroll bar with instance name: ...................sb1
a dynamic text field with instance name:.... tb1_txt
an external text file named as:....................home.txt
I want to make the scroll bar invisible or transparent, when
its is not needed. I'm thinking that I may have to use the _visible
property, but not sure of the correct code to integrate this.
Any suggestions anyone?

Answer 1

// Note:
Create a movie clip to put the code into
Use only 2 frames
Use 2 layers
Layer 1 put the action script
Layer 2 put the textarea and the scrollbar
Put a keyframe on each frame in only the Action Script layer.
The 2nd layer should only have a keyfram on the first frame
and span both frames 1 and 2.
On the first frame (do not put a stop() method here)
- set the visibility of the scrollbar to false
- set the text content / value of the textarea
On the second frame
- Put the action script
stop();
if(textDisplay.maxscroll > 1){
textscroll._visible = true;
} // if
