TakeUser, PROTECTED, VIRTUAL, PROC
The TakeUser method is called when an error with Level:User is “Thrown” to the ErrorClass (see Throw, ThrowFile, ThrowMessage).
TakeUser must return a severity level to denote the user's response.
Implementation:
The base class method (ErrorClass.TakeUser) displays the error message and returns either Level:Benign or Level:Cancel depending on the end user's response.
Return Data Type: BYTE
Example:
INCLUDE('ABERROR.INC') !declare ErrorClass
MyErrorClass CLASS(ErrorClass) !declare derived class
TakeUser FUNCTION,BYTE,VIRTUAL !prototype corresponding virtual
END
GlobalErrors MyErrorClass !declare GlobalErrors object
CODE
GlobalErrors.Init !GlobalErrors initialization
!program code
GlobalErrors.Throw(Msg:CreateFailed) !Throw method calls SELF.TakeUser to
!automatically call the derived class method
!rather than the base class method
!program code
MyErrorClass.TakeUser FUNCTION !derived class virtual to handle user errors

IF MESSAGE(SELF.SubsString(),SELF.GetErrorBufferTitle(),ICON:Question, |
