Abnormal delphi defined as follows:
TCustomException = class(Exception)
private
public
constructor Create(const Msg: string );
end;
In general programming, because it involves nested function calls this function if an exception occurs in a function, and there is try except statement, if you want a higher level function exception is caught, then call the raise statement except end ie can.
Abnormal general processing configuration programming language is generally
try
try
except
end;
finally
end;
That is a first except statement, handle exceptions, and then is finally statement to freed resource statement in the application.
