Greetings to everyone...
We're developing DLL, which installs our XPI package file - for installation
we used -install-global-extension, so now DLL installs XPI without starting
FF with install dialog.
But also we need to develop UnInstall method, which would uninstall xpi from
FF without user help.
I've noticed that such option we'll be available in FF 1.5, but we need to
make it work till that time and also we have to support earlier version of
FF.
I've noticed nsIExtensionManager service and managed to create uninstall
method in XUL (of Extension) - and it really works fine, here it is:
var ext = Components.classes["@mozilla.org/extensions/manager;1"].getService();
ext = ext.QueryInterface(Components.interfaces.nsIExtensionManager);
ext.uninstallExtension("our_extension_GUID");
But we need to put that func inside our XPCOM component... i've translated
it - but it doesn't work, here it is:
nsCOMPtr<nsIServiceManager> servman;
nsresult res = NS_GetServiceManager(getter_AddRefs(servman));
if (res == NS_OK)
{
nsCOMPtr<nsIExtensionManager> extMan;
res = servman->GetServiceByContractID("@mozilla.org/extensions/manager;1",
NS_GET_IID(nsIExtensionManager), getter_AddRefs(extMan));
if (res == NS_OK)
{
res = extMan->UninstallExtension("{our_extension_GUID}");
if (res == NS_OK)
{
MessageBox(NULL, "uninstall succeeded!", "!", MB_OK);
}
}
}
We always got message -- "Uninstall Succeeded", but Extension remain
uninstalled.
P.S> THNXm for attension, looking forward fr your help, guys.
