Hi,
I could not print out some HTML output to the browser before calling a vortex function that takes a long time..as I need to show up some page contents while the user is waiting for the process....
I tried to use the flush method,, but nothing happened...
here is a snippet of my script:


<flush>




..thanks,
Tamer

You have to be sure that the page can be rendered up to the point of the flush. IE: No open <tables> etc...

Try this:

<html>
<head></head>
<body>

Waiting...
<br>
<flush>
<functioncall>

The flush will guarantee that Vortex has sent the data. As mentioned, if the HTML is not complete enough to render, e.g. open tables it may not display, and some webservers may also be caching the content, which is beyond Vortex's control.

You can use the geturl tool to fetch the URL from the command line, and you should be able to see if the data is sent back to the browser when you expect.
