Remarks

For a brief description of these status values, see the following list:

  • COleCurrency::valid   Indicates that this COleCurrency object is valid.

  • COleCurrency::invalid   Indicates that this COleCurrency object is invalid; that is, its value may be incorrect.

  • COleCurrency::null   Indicates that this COleCurrency object is null, that is, that no value has been supplied for this object. (This is "null" in the database sense of "having no value," as opposed to the C++ NULL.)

The status of a COleCurrency object is invalid in the following cases:

  • If its value is set from a VARIANT or COleVariant value that could not be converted to a currency value.

  • If this object has experienced an overflow or underflow during an arithmetic assignment operation, for example += or *=.

  • If an invalid value was assigned to this object.

  • If the status of this object was explicitly set to invalid using SetStatus.

For more information on operations that may set the status to invalid, see the following member functions:
