Re: FLASH: OT: vbscript in Moock detect for Flash

[Helen Triolo]

Thanks for spotting that, Muzak.  (Could've sworn I'd checked that

myself, but you were right -- and Gregg too, offlist, thanks -- the end

if syntax was wrong).  But having fixed that, I encounter another weird

problem.  I've tried to simplify it to the least possible code to show

the problem and would appreciate any suggestions about why I get the

strange results I do:  I'm looking at just the detection for Flash in IE

when the Flash activex is disabled.


If I use one version of the code, it works fine.  It's at

http://i-technica.com/flashdetect/detect_ie1a.html.  With the activex

disabled (per Macromedia's instructions to make sure it really is

disabled), it tells me the actualVersion is 0 and pops up a gif as it

should.


The other version of the code, which I would've thought should produce

the same results is at

http://i-technica.com/flashdetect/detect_ie3a.html.  With no activex,

this version tells me the actualVersion is 5 and then does the "Do you

want to install and run Flash 5.0?" prompt.


So my first question is why does the second version think Flash 5 is

installed?


Then, even more strangely, if I add lines to dump out the intermediate

variables flash5installed and flash3installed, I get runtime errors in

both versions saying flash5installed is undefined.  (code located at

http://i-technica.com/flashdetect/detect_ie1.html and

http://i-technica.com/flashdetect/detect_ie3.html, respectively). If

anyone has looked at Moock's detection, you know about this

flash5installed variable. It is supposedly a global variable set to a

default value of false in javascript and later given a real value in a

vbscript routine, and then used to calculate actualVersion in another

javascript routine.  How can flash5installed be undefined and

actualVersion not be?


So my second question is why is this value (flash5installed) undefined,

and if it is, how is that first routine ever working correctly?  And how

does vbscript set a variable that was originally set in a javascript

routine anyway?


Sorry for such a long and complicated question.  If anyone else out

there cares enough about detecting Flash in IE to take a look at the

source behind those pages, I'd appreciate any enlightenment.


Regards,

Helen
