Hi,

I am trying to add an animation to an ASP page. The page is
OrderProcess.asp. The reason to add the animation is the OrderProcess.asp 
will take several mins., especially for a big order. I want to inform user 
that order is processing. Sometimes, user waits for a while, will close 
window or press Back. I want to show it as long as the OrderProcess.asp
started, and will redirect to another page (OrderConfirm.asp) when the
processing is done. 

Here's some pseudo code for an ASP processing page:

<%Option Explicit
Response.Buffer=true
Response.Write "<img src='pleasewait.gif'>"
Response.Flush	' Sends html without waiting until done
Call DoProcessing()
Server.Transfer "AllDone.asp"
Response.End

My problem is when I get to AllDone.asp, the pleaseWait.gif is still 
there. How can I clear PleaseWait.gif on AllDone.asp? In other words, how 
can I clear the flushed message?

Thanks for your help.

Hi there,

Maybe you can use some DHTML to display and hide the image:

Something like this may work:

    Response.Write "<img src='pleasewait.gif' id=""imgWait"" 
style=""display:inline;"">"

This will add a style definition telling the image to be visible as an 
inline element. SO far nothing new, because it was already visible.

Now right after your DoProcessing() method, add some JavaScript to hide 
the image:

    Response.Write(<"script type=""text/javascript"">" & vbCrLf)
    Response.Write(<"document.getElementById(""imgWait"").style.display 
= 'none';" & vbCrLf)
    Response.Write("</script>")

This will hide the image in the page by setting its display property to 
none.

Alternativey, you can use Response.Redirect instead of Server.Transfer. 
Response.Redirect tells the browser to request a new page, so once that 
gets loaded the old one (with the image) will be completely gone.

Hi Imar,

Thank you so much! I'll give a try.

Server.Transfer simply adds the ASP code in "Alldone.asp" to the end of the
page that called it, so your image will remain like you stated.

Could you not replace it with Response.Redirect "AllDone.asp" ?
At least that way it's a new page that's loaded.

Hi,

I am trying to add an animation to an ASP page. The page is
OrderProcess.asp. The reason to add the animation is the OrderProcess.asp
will take several mins., especially for a big order. I want to inform user
that order is processing. Sometimes, user waits for a while, will close
window or press Back. I want to show it as long as the OrderProcess.asp
started, and will redirect to another page (OrderConfirm.asp) when the
processing is done.

Here's some pseudo code for an ASP processing page:

<%Option Explicit
Response.Buffer=true
Response.Write "<img src='pleasewait.gif'>"
Response.Flush	' Sends html without waiting until done
Call DoProcessing()
Server.Transfer "AllDone.asp"
Response.End

My problem is when I get to AllDone.asp, the pleaseWait.gif is still
there. How can I clear PleaseWait.gif on AllDone.asp? In other words, how
can I clear the flushed message?

Thanks for your help.

Hi Craig,

Thank you! Actually I tried use Response.Redirect "AllDone.asp" first, 
but it didn't work, because of Flush. I can't give up Flush, so I tried 
Server.Transfer. I have to say using Response.Redirect is my solution. It 
works now. I used a little JavaScript to redirect. 

Thank you all for your help!
