Oops. I didn't consciously send the lines beginning <cid: in my previous message. Please treat the message as if they don't exist! -------- Original Message -------- Subject: Re: navigator.requestMIDIAccess() not defined in Chrome extensions Date: Thu, 21 Nov 2013 13:06:19 +0100 From: James Ingram <j.ingram@netcologne.de> To: Douglas Gore <doug@ssonic.co.uk>, Chris Wilson <cwilso@google.com> CC: Charlie Roberts <bigbadotis@gmail.com>, public-audio-dev@w3.org Hi all, Thanks Doug, but as I said, for some reason wampserver doesn't install properly here. It simply doesn't open when I double click its icon. Okay, so now I've got XAMPP up and running. I had to change some ports to avoid conflicts with IIS7, but that's all out of the way and its working properly. But I still have a problem. When I run file:///C:/xampp/htdocs/localAssistantPerformer/assistantPerformer.html <cid:part1.07020703.04080408@netcologne.de> I can embed files such as file:///C:/xampp/htdocs/localAssistantPerformer/scores/score1Page1.svg <cid:part1.07020703.04080408@netcologne.de> okay (That didn't work locally before.), but I can't call getSVGDocument() on the embedded page to get at its content. I get the following error message: > Blocked a frame with origin "null" from accessing a frame with origin > "null". Protocols, domains, and ports must match. Where do I go from here? Chrome extensions don't (currently?) work either... I'm investigating further, but maybe someone out there can help.
