Deleting text in a dynamic text box

[Rogerio62]

I am trying to delete the last character entered (be it alpha or numeric) into
a dynamic textbox (that i am populating using only buttons on a form). The
trick is I want to use a button to delete the last character. so far my code
for the delete button looks like

on(release)
var L = mytxt.length
Selection.setFocus("mytxt")
Selection.setSelection((L-1),L)
mytxt.replaceSel("")


however all this does is select the text and does not write over it. i have
tried every other way i know of and Flash will not write a null string over an
existing character. is there anyway to do this??

when you create your dynamic text box on the flash stage, you can assign a
variable to it (look at the properties window for VAR in flash mx). then, in
your code, if you change that variable, the contents of the textbox will change.

if myString is your variable, then you could do something like this

myString = myString.substring(0, myString.length);

or something like that....you might need to experiment.
