0-15 Specifies the repeat count. The value is the number of times the keystroke is repeated as a result of the user holding down the key.
16-23 Specifies the scan code. The value depends on the original equipment manufacturer (OEM)
24 Specifies whether the key is an extended key, such as the right-hand ALT and CTRL keys that appear on an enhanced 101- or 102-key keyboard. The value is 1 if it is an extended key; otherwise, it is 0.
25-28 Used internally by Windows.
29 Specifies the context code. The value is 1 if the ALT key is held down while the key is pressed; otherwise, the value is 0.
30 Specifies the previous key state. The value is 1 if the key is down before the message is sent, or it is 0 if the key is up.
31 Specifies the transition state. The value is 1 if the key is being released, or it is 0 if the key is being pressed. MSDN里的这个flag是32位的啊
0~15位应该就是体现一直按住情况的吧？

的意思好象是说这15位的意思是指一直按住某个键的重复次数吗？
可是我发现他好象真的包含了下面的含义：
0-7位————OEM扫描码
8——————扩展键标志
9-12————保留
13—————上下文代码
14—————先前键状态
15—————过渡状态
能帮我解释一下吗？谢谢！
