4 posts in this topic

since new Unicode AutoIT versions this lengths not equal:

$u = DllStructCreate ('byte[10]')
ConsoleWrite ("Size of structure: "& DllStructGetSize ($u) &@CRLF)
ConsoleWrite ("Size of data in structure: "& StringLen (DllStructGetData ($u,1)) &@CRLF)oÝ÷ Ù«­¢+ØÀÌØíÍ¥±ô]¥¹½ÝͥȵÀìÌäìÀäÈíÍÑÕÁй±½Ìäì(ÀÌØí¡¥±ô¥±=Á¸ ÀÌØíÍ¥±°Ð¤()
