MFC mciSendString 指定位置播放
用函数发送指令控制指定点位置播放,现在的播放器都有滑块用鼠标点到哪里就播放哪里
有知道的高手码
自己写了一段不能用
int nPos = m_slider.GetPos();
CString step;
long lPosition;
TCHAR szReturn[MAX_PATH] = { 0 };
lPosition = nPos;
step.Format(_T("seek movie to %ld"), lPosition);
_stprintf(szReturn, _T("%d"), nPos);
mciSendStringW(step, szReturn, MAX_PATH, 0);
把后面三个参数改为0也不行
