SetFileAttributes 功能:修改文件属性

这是一个修改文件属性的API

使用下面WINDOWS API函数

function SetFileAttributes(lpFileName: PChar; dwFileAttributes: DWORD): BOOL; stdcall;
{$EXTERNALSYM SetFileAttributes}
function SetFileAttributesA(lpFileName: PAnsiChar; dwFileAttributes: DWORD): BOOL; stdcall;
{$EXTERNALSYM SetFileAttributesA}
function SetFileAttributesW(lpFileName: PWideChar; dwFileAttributes: DWORD): BOOL; stdcall;
{$EXTERNALSYM SetFileAttributesW}

function SetFileAttributes(lpFileName: PChar; dwFileAttributes: DWORD): BOOL; stdcall; {$EXTERNALSYM SetFileAttributes} function SetFileAttributesA(lpFileName: PAnsiChar; dwFileAttributes: DWORD): BOOL; stdcall; {$EXTERNALSYM SetFileAttributesA} function SetFileAttributesW(lpFileName: PWideChar; dwFileAttributes: DWORD): BOOL; stdcall; {$EXTERNALSYM SetFileAttributesW}

实例：

SetFileAttributes('C:\test.exe',FILE_ATTRIBUTE_HIDDEN+FILE_ATTRIBUTE_SYSTEM);

下面是文件属性,对应dwFileAttributes



FILE_ATTRIBUTE_READONLY = $00000001;
{$EXTERNALSYM FILE_ATTRIBUTE_READONLY}
FILE_ATTRIBUTE_HIDDEN = $00000002;
{$EXTERNALSYM FILE_ATTRIBUTE_HIDDEN}
FILE_ATTRIBUTE_SYSTEM = $00000004;
{$EXTERNALSYM FILE_ATTRIBUTE_SYSTEM}
FILE_ATTRIBUTE_DIRECTORY = $00000010;
{$EXTERNALSYM FILE_ATTRIBUTE_DIRECTORY}
FILE_ATTRIBUTE_ARCHIVE = $00000020;
{$EXTERNALSYM FILE_ATTRIBUTE_ARCHIVE}
FILE_ATTRIBUTE_NORMAL = $00000080;
{$EXTERNALSYM FILE_ATTRIBUTE_NORMAL}
FILE_ATTRIBUTE_TEMPORARY = $00000100;
{$EXTERNALSYM FILE_ATTRIBUTE_TEMPORARY}
FILE_ATTRIBUTE_COMPRESSED = $00000800;
{$EXTERNALSYM FILE_ATTRIBUTE_COMPRESSED}
FILE_ATTRIBUTE_OFFLINE = $00001000;
