Demonstrates the use of numeric handles to represent objects in Excel
This add-in contains the code described in the User Guide topic Using object handles.
Numeric handles (as implemented in the NumericHandles.xpe
extension) consist of the object's address in memory.
This is the least verbose form of handle of the three styles available,
but it can be hard for the user to debug, since the addresses are large
meaningless numbers.
To edit the functions in this add-in, you need to load the extension file
NumericHandles.xpe.
See Loading an extension file
for instructions.
You should also make sure that neither of the following extension files is loaded, since the various types of handles are mutually exclusive.
RtdHandles.xpe
StringHandles.xpe
StringPtrHandles.xpe
CXlOper::operator = | CXlOper::Ret
