Description

VarDateFromStr is used to specify the function that makes the conversion from a WideString to a date value.

Use VarDateFromStr to specify the function that makes the conversion from the WideString given through strIn to the date value stored in dateOut. The LCID parameter is a locale identifier and dwFlags specifies the flags used in the conversion.

The function stored in VarDateFromStr returns the result of the conversion operation, which can be one of the following.
