Managed / Unmanaged Code?

[Dasmo]

I have a interface in a managed c++ file, is it possable to use this in an unmanaged c++ file.

I've tired using:

gcroot<MyManagedInterface*> myInterface

but this dosn't work, any help would be appectiated.

No. You can use unmanaged objects from managed code bot not vice versa.
