<p>You can use a combination of <cfflush>
and javascript to show a message on the screen while processing a large data
set (or any other long-running task).</p>
<!--- use cfflush to display the 'wait'
message right away --->
<cfflush interval="1">
<!--- show the message saying there
will be a delay --->
<p id="wait"
style="color:red; background-color: #CCCCCC; width:
200px; height: 50px;">Please wait while the data is processed.</p>
<!--- process your long-running
query or script (or anything) --->
<cfset total = 0>
<cfloop from="1" to="10000"
index="i">
<cfset total = total + 1>
</cfloop>
<!--- after the process is done, use
javascript to remove the 'wait' message --->
<script>
if (document.getElementById) {
wait.style.display="none";
}
</script>
<!--- now display the result --->
<p>The total is<cfoutput>#total#</cfoutput>.</p>
<p>Keep in mind
that this may not work if you have a lot of nested tables since ColdFusion can't
return results unless the ending tags can be flushed as well.</p>
