The autogenerated method works for me?
On the whole you should find that methods autogenerated from the Win32
type-library will not have that sort of error because they are directly from
the SDK header files. They may have minor issues with the parameter types,
however, as in this case the second BOOL parameter is interpreted as a long
integer. This is strictly correct since the Win32 BOOL type is just an
integer, but it is more usefully defined as a 'bool' in Dolphin (as Sean has
done) to get automatic marshalling of Smalltalk Booleans.
