Hm, that's odd...

Here's what I've got in 'grid.prg':

DEFINE CLASS hdr AS Header
  Name     = "hdr"
  Caption  = "  Header  "
  FontFace = "Tahoma"
  FontSize = 8
ENDDEFINE

DEFINE CLASS col AS Column
  Name               = "col"
  HeaderClass        = "hdr"
  HeaderClassLibrary = "t:\baseclasses\grid.prg"

  ADD OBJECT txt AS txt
ENDDEFINE

The class 'txt' is, of course, my visual base class in t:\baseclasses\baseclasses.vcx.

Here're the properties for my grid class:

MemberClass        = col
MemberClassLibrary = "t:\baseclasses\grid.prg"

When I try to open the grid in the class designer, I get an error: "Class definition TXT is not found." So just for kicks-n-grins, I tried it like this:

DEFINE CLASS col AS Column
  Name               = "col"
  HeaderClass        = "hdr"
  HeaderClassLibrary = "t:\baseclasses\grid.prg"

  ADD OBJECT txt AS txt OF t:\baseclasses\baseclasses.vcx
ENDDEFINE

As expected, I get a compile-time error: "Command contains unrecognized phrase/keyword."

How did you get it to work? You must have SET CLASSLIB to your base class' .VCX -- that's the only thing I can think of.
