Data Type: Numeric or String

Return Value

expression cast as a Variant.

Description

Returns expression as a Variant data type; the data subtype is automatically selected by the CVar routine.

Rules at a Glance

There really aren't any rules: you can literally throw anything at CVar, and a variant of the appropriate data subtype is returned.

Programming Tips and Gotchas

Use CVar only in situations where you are confident that the data type you pass into the function isn't ambiguous; in other words, where you can be sure of the data subtype that CVar selects. If you need data of a particular data type, use the appropriate conversion function.
