    IsDatabaseCurrentFormatVersion Property
    In This Topic
    Whether the format version of this database is the current version (the latest version known to this version of the VistaDB provider engine).
    Syntax
    'Declaration
     
    
    ReadOnly Property IsDatabaseCurrentFormatVersion As System.Boolean
    'Usage
     
    
    Dim instance As IVistaDBDatabase
    Dim value As System.Boolean
     
    value = instance.IsDatabaseCurrentFormatVersion
    System.bool IsDatabaseCurrentFormatVersion {get;}
    Remarks
    If true then this database is already in the format used by this version of the VistaDB engine. If false then a Pack operation will upgrade the format of this database and it may become inaccessible to applications using an older version of VistaDB. Some recent older versions (VistaDB 4) may be opened in read-only mode and allow interactive access without requiring a Pack. However, a Pack operation will always upgrade to the latest format known to the engine being used. VistaDB 5 can also open the VistaDB 5.0 format for writing without performing an upgrade to the 5.1 format, but a Pack operation will upgrade to the current format for the VistaDB engine which performs the Pack.

    Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
