Comments
LayOut assigns VTBL offsets for virtual functions and instance offsets for
per-instance data members, and creates the two typeinfos for dual interfaces. LayOut also assigns member ID numbers to the functions and variables unless the
TYPEKIND of the class is TKIND_DISPATCH. LayOut should be called after all members of the type information are defined and
before the type library is saved.
Use SaveAllChanges to save the type information after calling LayOut. Don't call other members of the ICreateTypeInfo interface after calling LayOut.
Note that different implementations of ICreateTypeInfo or other interfaces that create type information are free to assign any
member ID numbers, provided that all members, including inherited members, have
unique IDs.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
