Media Player 6.4

1, 怎么获得 01:50 / 03:20 这个播放时间?

2, OnError怎么捕获错误码?

3, OpenState, PlayState的值哪有文档? MSDN上找不到具体值(可能是我没找到)

来自window media sdk,但是我的实践中数值好像不对,0的状态好像没有,其他状态数值减一!
也就是Stopped状态其实是0,Paused状态是1 ... 以此类推

wwwllg(wwwllg) :


unsigned long total = (unsigned long)m_pMedia->GetDuration();

为什么total总是334???????

GetDuration是总时长， Position是当前时段
