Hi, I had trouble using Wx::ActiveX, accessing methods and properties in particular. One problem was that the GetOLE method did not work, which turned out to be because I did not load the module myself first. That should be mentioned in the documentation (or it should load it itself, if that is a suitable option). The other is that PropVal seems to turn values into strings, even though say Wx::ActiveX::IE lists properties as being of other types like IDispatch, so often I just got "[object]". This stringification should also be mentioned in the documentation. (So far I'm using $ie->GetOLE()->Document to get to a proper Document object I can call method like createElement on, not sure if that is the best way.) It might also be worth noting that applications hosting Internet Ex- plorer will default to running in IE7 compatibility mode when IE9 is installed, meaning new features will be unavailable and others might not work as expected. The only way to change that would be through a <meta content="IE=9" http-equiv="X-UA-Compatible" /> meta header in the HTML document, a corresponding HTTP header when HTTP is used, or a "Feature Control" setting in the registry for the executable this is meant to apply to (which in case of perl.exe would be perl.exe). I at least know no other way, though I do see that the F12 debugger can change the setting on a per-tab basis using some means I've not seen documented anywhere. regards, -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.

I should document this. You only ever get a string back from Propval Show quoted text

This is the only way - but it works perfectly well. I will document the necessity to 'use Win32::OLE' and use of ->GetOLE for anything other than a string representable value. Show quoted text

http://msdn.microsoft.com/en-us/library/aa770041(v=vs.85).aspx#IDocHostUIHandler2 has the answer. I will look at implementing this as it will allow you to override all of WebControl's settings on a script by script basis. Regards Mark
