Description

Converts the Variant.

This operator returns a type that is a conversion of this Variant. If the T* conversion is used, the operator sets the varByRef bit, meaning that the Variant contains a reference as opposed to a value.

If the conversion operation is not possible because of an invalid variant type conversion, an EVariantError exception is thrown.

Note: Do not call the implicit conversion operator directly. It is an overload of the compiler conversion operation.
