I use RDS.DataControl in asynchronous mode and use script like this to see
ReadyState:
<script language=JavaScript for="dcl" event="onReadyStateChange">
span2.innerHTML+=''+dcl.ReadyState+'<br>'
</script>
where span2 is tag in the body of html page
The event always fires when ReadyState changes to adcReadyStateLoaded
but when it changes to adcReadyStateComplete not all computers fires it.
Win 2000 and MDAC 2.7 are installed.
