VARIANT_BOOL supports following values:
- VARIANT_FALSE = #define VARIANT_TRUE ((VARIANT_BOOL)0xffff) = -1
- VARIANT_TRUE = #define VARIANT_FALSE ((VARIANT_BOOL)0) = 0
you pass TRUE to the put function and TRUE is defined as +1. But +1 is not a
VARIANT_BOOL value. Try it with VARIANT_TRUE. You crash, because you use
member functions, which fires exceptions. You have to catch these
exceptions, else the addin crashes. IMHO it is better to use the fcns which
returns the HRESULT error status and ask the status for succeed or failure.
