SetErrorMode()

Queries or changes the behavior with operating system errors.

Syntax

SetErrorMode( [<nNewErrorMode>] ) --> nOldErrorMode

<nNewErrorMode>

This parameter is a numeric value of 0 or 1. Other values are ignored.

Return

Description

Function SetErrorMode() instructs the operating system how an xHarbour application handles errors that occur on the operating system level. For example, when function DiskChange() is called and the specified disk drive has no disk inserted, the operating system would display a message box prompting the user for inserting a disk. To suppress message boxes displayed by the operating system, SetErrorMode(1) must be called.

SetErrorMode(0) enables the display of message boxes created by the operating system.
