I am using the window.open function to run some reports using crystal. Some of these reports are large. How can I display a message or something telling the user "Processing Report..Please Wait"

Right now the window opens blank until the report gets populated.

any help would be appreciated..

thanks

Dim strRedirect As String

strRedirect = "../ReportsMenu/ReportName.aspx"
Response.Write("<script language='javascript'>" & vbCrLf)
Response.Write("wndcht=window.open('" + strRedirect + "','_new', 'toolbar=no,menubar=no,location=no,resizable=yes,scrollbars=yes,left=0,top=0');")
Response.Write("<" & "/" & "script" & ">" & vbCrLf)

You should just be able to display a please wait message as you would do with any standard HTML page (i.e. with a mixture of javascript and CSS)

I tried
Response.Write("wndcht=window.load = function () {alert('Please Wait!');}")

Can't get this to fire off..

I suggest, instead of a popup, to have a label on the page that says "Pleas wait, retrieving data ..." Then once the report loads, set the label to visible = FALSE.

Also have a look at the Response.Flush() method of .NET

You shouldn't use Response.Write to write data out to your page (unless you are testing). If you search google for "Please Wait Javascript CSS" you will get lots of simple examples on how to do it, such as:

Yes, using Response.Write() is an improper,

but i guess thats the only way to display the preliminary message.

i wrote a small ASPX file:
Code: 
<%@ import namespace="System.Threading"%>
<script runat="server">
	sub page_load
		response.write("ASD")
		response.Flush()
		Thread.Sleep(5000)
	end sub
</script>

<!-- ONE STEP TO INSTALL PRE-LOADING MESSAGE:



  1.  Copy the coding into the HEAD of your HTML document  -->



<!-- STEP ONE: Paste this code into the HEAD of your HTML document  -->



<HEAD>



<style type="text/css">

<!--

#loading {

	width: 200px;

	height: 100px;

	background-color: #c0c0c0;

	position: absolute;

	left: 50%;

	top: 50%;

	margin-top: -50px;

	margin-left: -100px;

	text-align: center;

}

-->

</style>



<script type="text/javascript">

window.onload=function(){

	document.getElementById("loading").style.display="none";

}

// End -->

</script>

If u notice the CSS loading NEVER comes, thats cause the Javascript coding itself is outputted only at the end of execution (.NET always outputs ALL html together)...

Another alternative is to redirect the user to a holding page and only forward them onto the relevant page once the processing has finished. e.g.
