I have a dll which I generated a tlb for and am referencing that tlb
from VBA in Excel (2003). When I try to create and use any custom
defined typedef, I get a "Variable uses an Automation type not supported
in Visual Basic" on compilation. For example, this from the tlb:

struct tagPageDimension {
LPSTR dimensionName;
LPSTR MemberName;
} PageDimension;

then this line in the VBA causes the error:

Dim oTemp As MyClass.PageDimension

Additionally, on the intellisense, I don't get the members when I then do:
oTemp. (dimensionName and MemberName should come up but don't)

Can anyone help?
thanks!
