Here's the old way of trying to declare variables inside VBScript and passing those values to Javascript.

Note: I've reduced the code to only the VBScript part of it, if you've dealt with this before, it should evoke instant bad memories.
<script language="javascript">
document.write('<script language=VBScript\> \n');
document.write('on error resume next \n');
document.write('hasFlash = (IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash.4"))) \n');
document.write('</script\> \n');

With the old way, there tend to be errors that state that one can't have script tags within a block of script. It is cumbersome, and has never worked for me.

Here's a different way using a javascript try/catch, and the instantiation (or failure) of ActiveXObject's take on flash.

<script language="javascript">
if(navigator.appName.indexOf("Netscape")==-1){ var flashObj; try{ /* attempt to create an instance of the flash object, if it is capable of being created, it can be treated as a boolean TRUE */ flashObj = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.5") //in other words TRUE } catch(error){ flashObj = false } if(flashObj){ alert("do the flash stuff"); }else{ alert("do something else"); } } </script>
Note: the Netscape check, there are navigator.plugin properties that you can use for Netscape.

Try this out by changing the 5 to a 6 for the Flash version. Happy version checking!

If you find that this doesn't work for different platforms, e-mail me at
