    Description This procedure defines the properties which are required to support the verification of saves, deletes, and losses of changed data. Assumptions/Preconditions None. Exceptions None. Notes Though defined as private, access procedures and functions are defined for these properties below (to make them public). Verify_Save_Msg holds the message id to be sent to verify a Save operation. Verify_Delete_Msg holds the message id to be sent to verify a Delete operation. Verify_Data_Loss_Msg holds the message id to be sent to verify an action which may cause the user to lose changes to the data in items.
    • integerprivate.Verify_Save_Msg
    • integerprivate.Verify_Delete_Msg
    • integerprivate.Verify_Data_Loss_Msg
  • Set(Integer val)
    Description This procedure sets the value of the Verify_Save_Msg property. Assumptions/Preconditions None. Exceptions None. Notes None.
  • Set(Integer val)
    Description This procedure sets the value of the Verify_Delete_Msg property. Assumptions/Preconditions None. Exceptions None. Notes None.
  • Set(Integer val)
    Description This procedure sets the value of the Verify_Data_Loss_Msg property. Assumptions/Preconditions None. Exceptions None. Notes None.
  • integerVerify_Save_Msg()
    Description This function returns the message id to be used to verify a Save operation. Assumptions/Preconditions This object must understand Component_State. Exceptions If this object's Verify_Save_Msg is 0, the value of this object's parent's Verify_Save_Msg is returned, if any. Notes None.
    • Integerretval
  • integerVerify_Delete_Msg()
    Description This function returns the message id to be used to verify a Delete operation. Assumptions/Preconditions This object must understand Component_State. Exceptions If this object's Verify_Delete_Msg is 0, the value of this object's parent's Verify_Delete_Msg is returned, if any. Notes None.
    • Integerretval
  • integerVerify_Data_Loss_Msg()
    Description This function returns the message id to be used to verify an operation which may cause the user to lose changes to the data in items. Assumptions/Preconditions This object must understand Component_State. Exceptions If this object's Verify_Data_Loss_Msg is 0, the value of this object's parent's Verify_Data_Loss_Msg is returned, if any. Notes None.
    • Integerretval
  • integerVerify_Save()
    Description This function confirms a Save operation with the user, returning 0 if the Save should continue, or non-zero if the Save should be aborted. Assumptions/Preconditions None. Exceptions If the Verify_Save_Msg function returns 0, no action is taken. Notes None.
    • Integermsg#
    • Integerretval
  • integerVerify_Delete()
    Description This function confirms a Delete operation with the user, returning 0 if the Delete should continue, or non-zero if the Delete should be aborted. Assumptions/Preconditions None. Exceptions If the Verify_Delete_Msg function returns 0, no action is taken. Notes None.
    • Integermsg#

  • integerVerify_Data_Loss()
    Description This function confirms an operation (which may cause the loss of changed data in items) with the user, returning 0 if the operation should continue, or non-zero if the operation should be aborted. Assumptions/Preconditions None. Exceptions If the Verify_Data_Loss_Msg function returns 0, no action is taken. Notes None.
