Bar Code 39

This component is broken as is.  Since a movie clip is created to be copied to layout the entire barcode, if that movie clip is not removed then an extra line lies at the front of the code.  When limiting the code in the standard way - "*code*" -  many scanners will not read the code because of this extra line, although some scanners will read the code because those scanners find the correct starting point of the code even if there is an extra line out front.

It is proper to add this line of code after the barcode has been generated:

this.bars_mc.bar_mc.removeMovieClip();

It will remove the source line.

The position of the code line is described below.

    var draw_array = bars_str.split("");
    for(var i = 0;i < draw_array.length; i++){       
        barDepth++;
        var drawBar = int(draw_array[i]);
        if (drawBar){
            the_mc = this.bars_mc.bar_mc.duplicateMovieClip("bar"+barDepth+"_mc", barDepth);
            the_mc._x = barDepth;
        }
    }
   
    this.bars_mc.bar_mc.removeMovieClip();


It is also proper to add the delimiter to the code inside of the class so you don't need to add it outside of the class.:

var my_str = "*"+this.the_str+"*";


Bare bones, out of the box, you would enter the code *WIKIPEDIA* like the wiki page for code 39 and you will see that this generator produces 1 extra line out in front of the code.  As described above, it is the un-removed movie clip that is used as a copy source for the lines in the barcode.
