            oForm.Items.Add ( "Folder " , BoFormItemTypes.it_FOLDER )

            oForm.Items.Item ( "Folder "). oForm.Items.Item Top = ( "146" ) . Top
            oForm.Items.Item ( "Folder "). oForm.Items.Item = Left ( " 234000005 ").oForm.Items.Item + Left ( " 234000005 "). Width
            oForm.Items.Item ( "Folder "). LinkTo = " 13"
            oForm.Items.Item ( "Folder "). AffectsFormMode = False
            Me.oForm.Items.Item ( "Folder "). SetAutoManagedAttribute ( BoAutoManagedAttr.ama_Editable , 1, BoModeVisualBehavior.mvb_True )
