INTRODUCTION:
=============
The following sample code shows how to call the Win32 API function
called DeleteFile. This function deletes an existing file. If an
application attempts to delete an open file or a file that does not
exist, the function fails.
This code has been tested on Windows NT 4.0 Workstation only.
DEFINE VARIABLE intResult AS INTEGER NO-UNDO.
PROCEDURE DeleteFileA EXTERNAL "KERNEL32.DLL":
DEFINE INPUT PARAMETER chrFileName AS CHARACTER.
DEFINE RETURN PARAMETER intResult AS LONG.
END PROCEDURE.
RUN DeleteFileA ("C:\BRIAN.TXT", OUTPUT intResult).
IF intResult = 1 THEN
MESSAGE "DeleteFile Worked" VIEW-AS ALERT-BOX.
ELSE
MESSAGE "DeleteFile Failed" VIEW-AS ALERT-BOX.
