I am trying to wrap IOleContainer and having trouble getting the ENumObjects
declaration correct.
This is what I have so far:
[ComImport,
Guid("0000011B-0000-0000-C000-000000000046"),
InterfaceTypeAttribute(ComInterfaceType.InterfaceI sIUnknown)]
public interface IOleContainer
{
void ParseDisplayName(
[In, MarshalAs(UnmanagedType.Interface)] object pbc,
[In, MarshalAs(UnmanagedType.BStr)] string pszDisplayName,
[Out, MarshalAs(UnmanagedType.LPArray)] int[] pchEaten,
[Out, MarshalAs(UnmanagedType.LPArray)] object[] ppmkOut);
void EnumObjects([In, MarshalAs(UnmanagedType.U4)] int grfFlags,
[Out, MarshalAs(UnmanagedType.LPArray)] object[] ppenum);
void LockContainer([In, MarshalAs(UnmanagedType.I4)] int fLock);
}
Any suggestions?

Sheldon,
When you come across IEnumUnknown, that is an interface pointer that is
being returned, so you need to actually declare that interface type, and
then pass it by ref (with the ref keyword), or, you can always pass an
IntPtr by ref (and ignore it).
Hope this helps.
