VB Extensibility library and "late binding"

[Dennis]

XL 2003

Would like to strip all VBA code especially Excel 4 macro sheets.

The code below is from Jim Rech.

The problem is that when I run the code it produces an error message (with
"ThisRef As Reference" - as the highlighted stop point):

Compile error
User-defined type not defined


In my Google research, I found some references to "late binding".

This is my first time with
1)VB Extensibility library or
2)"late binding" (I have no clue)

How do I modify the code below?

I am assuming that the reason there is no reference in the code is because
the VB Extensibility Library can be different for each XL installation.

Any help with as to the underlying theory would be a plus.

TIA

Dennis
