I'm not that good at the internals of Windows and such to figure all
that out.

Wow, that is impressive. Very nice demo the programmer made.
Awesome! Exactly what I was looking for.

Okay, I can understand that. But I will say that, as often as not,
it's the implementation details that obscure the actual task being
accomplished. When looking at samples like this, zero in on the Select
Case block in the message sink routine, where different code is
executed based on which message is recieved. That part is almost
always directly transplantable between any one of the numerous methods
for actually accomplishing the subclass.

As an example, if I want to track the user resizing a window, and
potentially limit that activity, this is really all there is to it:

Dim mmi As MINMAXINFO
Dim EatIt As Boolean

' Special processing for messages we care about.
Select Case uiMsg
Case WM_GETMINMAXINFO
If m_Enabled Then
' Snatch copy of current minmax.
Call CopyMemory(mmi, ByVal lParam, Len(mmi))
' Give client chance to alter defaults.
RaiseEvent GetMinMax(mmi.ptMinTrackSize.x,
mmi.ptMinTrackSize.y, _
mmi.ptMaxTrackSize.x,
mmi.ptMaxTrackSize.y)
' Make sure maximum really is maximum, to avoid flash.
mmi.ptMaxSize = mmi.ptMaxTrackSize
' Send altered values back to Windows.
Call CopyMemory(ByVal lParam, mmi, Len(mmi))
EatIt = True
End If

That snippet can really be moved from project to project to project,
almost without consideration whatsoever of what means are being used to
actually hook the message.

That is a very impressive piece of work, there!
