Update example usage for IDiaSymbol::get_value

Michael-K-Stein · web-flow · commit d75523ac2a62 · 2024-11-15T21:18:54.000+02:00
I believe that using `VariantInit` from oleauto.h is more future-proof rather than manually initializing the VARIANT's fields in case the internal implementation of VARIANT/VARIANTARG changes.
