No, on my knowledge. I use a simple javascrit to do this task; It looks like:


// count the available char before a max number of char
//usage: onKeyup="calcCharLeft(this,###)" onFocus="calcCharLeft(this,###)"
function calcCharLeft(Target,maxChar) {
  StrLen = Target.value.length;

  if (StrLen > maxChar ) {
    Target.value = Target.value.substring(0,maxChar)
    CharsLeft = 0
    window.alert("Lunghezza stringa eccessiva di: " + 
(StrLen-maxChar) + " carattere/i");
  } else {
    CharsLeft = maxChar - StrLen
  }

  document.forms[0].charsleft.value = maxChar - Target.value.length

}



in the HTML form use:

<TEXTAREA NAME="textImput" ROWS="4" COLS="40" 
onKeyup="calcCharLeft(this,100)" onFocus="calcCharLeft(this,100)">

</TEXTAREA>

Microsoft will figure out a way to own it.
