Hello,
If I drag an xpi into Firefox that containins the install.js file shown
at the bottom of this post, the extension I wrote cannot instantiate an
instance of the component in mycomponent.dll. The component and typelib
are placed in c:\program files\myapp\, as expected, but it seems like
the component doesn't get registered...after restarting Firefox, the
Components.classes[cid].createInstance() call made in the XUL throws
"Components.classes[cid] has no properties".
If I change install.js so that mycomponent.dll and IMyTypelib.xpt wind
up in the components folder (c:\program files\mozilla
firefox\components\), the call to createInstance in the XUL succeeds.
Any idea why the createInstance result is different depending on where
the component/typelib are located?
Thanks,
Roy
var err = initInstall("myextension", "myextension", 1.0);
var appFolder;
var putChromeHere;
if (err == SUCCESS) {
appFolder = getFolder("file:///", "c|/program%20files/myapp");
///appFolder = getFolder("Components");
putChromeHere = getFolder(appFolder, "myextension");
}
if (err == SUCCESS) {
err = setPackageFolder(putChromeHere);
}
if (err == SUCCESS) {
err = addDirectory("myextension", "myextension", putChromeHere, "");
}
if (err == SUCCESS) {
err = addFile("mycomponent.dll", "1.0",
"components/mycomponent.dll", appFolder, "");
}
if (err == SUCCESS) {
err = addFile("IMyTypelib.xpt", "1.0", "components/IMyTypelib.xpt",
appFolder, "");
}
if (err == SUCCESS) {
err = performInstall();
}
if (err == SUCCESS) {
err = refreshPlugins();
alert("please restart");
}
if (err != SUCCESS) {
cancelInstall(err);
