void main( void )

}方法2：

if (invalid_handle_value != createfile("d://a.txt", generic_read, file_share_read, null, open_existing, file_attribute_normal, null))

方法3：

#define _win32_winnt 0x0400

#include

方法4：

if (getfileattributes("c://1.txt") == -1)

messagebox(0."invalid file ","hehe",0)

else

messagebox(0."the first file found ","haha",0)

方法5：

if (invalid_handle_value != createfile("d://a.txt", 0, 0, null, open_existing, 0, null))
