#include <unknwn.h>
[module(name="MyLib")];
[object, uuid("00000000-0000-0000-0000-000000000001")]
__interface IMyForm
{
[propget, id(1), bindable, defaultcollelem, displaybind, defaultbind, requestedit] HRESULT P1([out, retval] long *nSize);
[propput, id(1), bindable, defaultcollelem, displaybind, defaultbind, requestedit] HRESULT P1([in] long nSize);
