Providers use DBPROPSTATUS values to return information about whether property values could be set. DBPROPSTATUS is used in the DBPROP structure.
The values of DBPROPSTATUS have the following meanings.
DBPROPSTATUS values
| Value | Description |
| DBPROPSTATUS_OK | The property's value was successfully set. This includes the case where the value of a read-only property was set to its current value. |
| DBPROPSTATUS_BADCOLUMN | The colid element of the DBPROP structure was invalid. |
| DBPROPSTATUS_BADOPTION | The value of dwOptions was invalid. |
| DBPROPSTATUS_BADVALUE | The data type in vValue was not the data type of the property or was not VT_EMPTY. For example, the property was DBPROP_MEMORYUSAGE, which has a data type of VT_I4, and the data type was VT_I8. The value in vValue was not a valid value. For example, the property was DBPROP_MEMORYUSAGE and the value was negative. The value in vValue was a valid value for the property, and the provider supports the property as a writable property, but the provider does not support the value specified by vValue. |
| DBPROPSTATUS_CONFLICTING | The property's value was not set because doing so would have conflicted with an existing property. |
| DBPROPSTATUS_NOTALLSETTABLE | A property was specified to be applied to all columns, but could not be applied to one or more of them. |
| DBPROPSTATUS_NOTSET | The property's value was not set to the specified value because dwOptions was DBPROPOPTIONS_OPTIONAL and setting the property to the specified value would not have been possible. |
| DBPROPSTATUS_NOTSETTABLE | The property was read-only or the consumer attempted to set values of properties in the Initialization property group after the data source object was initialized. Consumers can set the value of a read-only property to its current value. |
| DBPROPSTATUS_NOTSUPPORTED | The property's value was not set because the provider did not support the property, the provider did not support the property set, or the consumer attempted to get or set values of properties not in the Initialization property group and the data source object is uninitialized. The provider may return DBPROPSTATUS_NOTSUPPORTED for properties that do not apply to the provider. For example, a read-only provider may return DBPROPSTATUS_NOTSUPPORTED if the consumer called IDBProperties::SetProperties or IDBProperties::GetProperties for DBPROP_UPDATABILITY, or may return DBPROPFLAGS_NOTSUPPORTED if the consumer called IDBProperties::GetPropertyInfo for DBPROP_UPDATABILITY. |
