| Is the field virtual? |
| |
 |
VARIANT_BOOL IsFieldVirtual (
enum eFBookFld eFieldID
) |
|
| |
| Parameters | | eFieldID | [in] Identifier of the field, e.g. fbofSysNum (C++) or eFBookFld.fbofSysNum (C# / VB.NET).
| |
| Warning: DO NOT hardcode numeric values for field identifiers. The numeric value of a field (i.e. the enum value) can change from one version to the next. Always use the enum or use GetFieldID |
| Warning: DO NOT assume the order of fields will remain the same (do not calculate relative fields). fbofSysNum + 15 may not be valid or the same in future versions. |
| Remark: In VBS, this field identifier enumerations cannot be used! You should use GetFieldID to get a valid field identifier. |
| Remark: Within an object, field identifiers will not change as long as the object persists. You can obtain a value with GetFieldID once and then continue using the value. However, note that custom calculation fields are unique per dossier; even if they have the same field name, they may not have the same numeric value in all dossiers. |
