ActiveX

[pilsjart]

Hello there...

Can anyone tell me how can I tell if a MSIE user can see a activeX feature (like style.filter=flipv())? And... does it work in Mc or just im Windows?

well... thank you

style.filter="flipv()" is javascript that manipulates css. its not activeX. if they have javascript enabled on their browser it should work in ie on win.... dont know about macs. i dont have one.

This code may change the css, but still, this "filter" thing is an ActiveX feature. As far as I know, some property must be enabled in your browser in order to view something like "something.style.filter='(opacity=50,enabled=1)'";

So... is there anyone who can tell me how can I tell if the user is able to view that code or he isn't?


...thanks again...

filter is NOT activeX. it is an Internet Explorer css feature.
I think filter is used in IE5+

Actually opacity is IE4+ but most filters are IE5.5 (sp2) +

But eak is correct - it is nothing to do with activeX. If you want to detect filter support you need a two-stage check

if(typeof obj.filters !="unknown" && typeof obj.filters["filtername"] !="undefined") { ... filters are supported and the filter-property exists ... }

Granted that filters can be defined via CSS and manipulated thereafter via JS... but I believe that when actually *rendering* the filter IE uses DirectX internally.

At least, that's what the syntax suggests...
STYLE="filter: progid: DXImageTransform.Microsoft.filtername(sProperties)"

...

pilstart, I know that Transitions can be enabled/disabled by the user, but not Filters as such (that I know of), though the two are related. The switch is in:

IE/Tools/Advanced/Browsing/Allow page Transitions

In my tests, Filters are enabled whether or not Transitions are enabled.

...

Also note that Mozilla and Netscape 6 implement (at least some) filters, but their performance can be somewhat problematic.

Also, here's a URL for you, if that's helpful:

Brothercake:

I've used typeof obj.filters["filtername"] !="undefined" to sniff out filters with (apparent) success, but not typeof obj.filters !="unknown" cuz it didn't seem needed. Am I missing something?

PS: according to the URL I posted above, filters are WIN only - no MACs.
