Contents of this lesson:
> The power and limits of resources.
> Packed message arguments, manual unpacking.
> Use a separate message handler function for each message.
> Unpack arguments via undocumented message cracker macros.
> Be pedantically correct: support message results.
This lesson’s main points:
* Windows window messages are much like C++ virtual functions.
* The packing and unpacking of messages, having messages as data,
introduces some complexity.
* Dialog procedures impose special (complex) requirements on message
handling.
Cheers & enjoy,
- Alf
