DdfSetOwner

Can be used to set the Btrieve owner name for the dictionary files to something other than the default owner name and security level (allow read-only access). Owner name and security level parameters follow Btrieve conventions.

object.DdfSetOwner(NewOwnerName, SecurityLevel)

The syntax for this method has the following parts:


Part	Description
object	Required. The object placeholder represents an object expression that evaluates to an object in the Applies To list.
newOwnerName	a string to assign an owner name to the table
SecurityLevel	integer representing a security level

The following Security Level codes may be passed to DdfSetOwner in the SecurityLevel parameter:


Code	Global Constant	Description
0	EXCLUSIVE	Does not allow the file to be opened unless the correct owner name is specified.
1	READONLY	Permits users who do not specify an owner name to view, but not to modify the table.
2	EXCLUSIVE_ENCRYPT	Does not allow the file to be opened unless the correct owner name is specified. Data is encrypted within the file.
3	READONLY_ENCRYPT	Permits users who do not specify an owner name to view, but not to modify the table. Data is encrypted within the file.

Constant declarations are included in the files GLOBAL.BAS (for 16 bit Visual Basic), GLOBAL.BAS (for Visual Basic), GLOBAL.PAS (for Delphi), and GLOBAL.H (for Visual C++). Include one of these files (whichever is appropriate for your development environment) in your project to use the Security Level constants in your application.
