After a couple of days of debugging , I am able to start the update service
when application startup, but during the checkForUpdates, when trying to
open xmlhttprequest for update.xml, I got this error:
JavaScript Error: "[Exception... "Cannot modify properties of a
WrappedNative" nsresult: "0x80570034 (NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN)"
location: "JS frame ::
file:///c:/Development/Client/Bin/Debug/components/nsUpdateService.js ::
anonymous :: line 1745" data: no]"
in lines :
this._request.onerror = function(event) { self.onError(event); };
this._request.onload = function(event) { self.onLoad(event); };
this._request.onprogress = function(event) { self.onProgress(event); };
And I checked the doc of nsIXMLHttpRequest.idl, it says these are meant to
be script-only mechanism, and should not be used from native code. But this
error seems tell that I tried to use it from native code, I don't know
what's wrong.
Could anyone help me out with this?
Thanks,
Kate.
