Occurs when there is a run-time error in a method.
Syntax
PROCEDURE Object.Error
LPARAMETERS [nIndex,] nError, cMethod, nLine
Parameters
Visual FoxPro passes the Error event three or four parameters in the following order:
nIndex
Uniquely identifies a control if it is in a control array.
nError
Contains the Visual FoxPro error number.
cMethod
Contains the name of the method that caused the error. However, if a method calls a user-defined function, and an error occurs within that function, cMethod contains the name of the user-defined function, rather than the name of the method that called the function.
nLine
Contains the line number within the method or user-defined function that caused the error.
Remarks
The Error event allows an object to handle errors. This event overrides the current ON ERROR routine and allows each object to trap and handle errors internally.
Important The Error event is called only when the error occurs in code.
