Contains the code for the HandleAPI sample in the User Guide

Status

The code in this add-in demonstrates the old hand-written mechanism for creating and maintaining object handles. All this functionality can be achieved without coding, using one of the handles extensions as described in the User Guide topic Using object handles.

For an up-to-date handle sample, see the NumericHandleDemo sample, which was written using the NumericHandles.xpe extension.

Remarks

This project demonstrates the use of object handles in an XLL+ add-in.

For more details see Object handles using pointers in the User Guide.
