Value	Meaning
VAR_OK	The conversion was successful.
VAR_BADVARTYPE	The variant type of the input parameter is not valid.
VAR_OVERFLOW	The data stored in the output parameter does not fit in the destination type.
VAR_TYPEMISMATCH	The argument cannot be cast to the specified type.
VAR_INVALIDARG	Either one of the arguments is invalid.
VAR_OUTOFMEMORY	There is not enough memory to complete the conversion.

Note: To do the conversion using locale-specific information, use the function referenced by the VariantChangeTypeEx variable.
