1.long total = (long)m_player.GetDuration();
CString time  = GetStringTime(total);
CString CProgramer_EditView::GetStringTime(long sec)
{
int h = 0;
int m = 0;
int s = 0;

if(sec >= 3600)
{
h = sec / 3600;
m = (sec - 3600*h)/60;
s = (sec - 3600*h - 60*m);
}else
{
m = sec/60;
s = sec - 60*m;
}
CString str;
str.Format("%d:%d:%d",h,m,s);
return str;

}2.TRY{
if(leftvoice == LEFT_SD)
m_vidoHold.m_media.SetBalance(LEFT_SD);
else if(leftvoice == RIGHT_SD)
m_vidoHold.m_media.SetBalance(RIGHT_SD);
else
m_vidoHold.m_media.SetBalance(ALL_SD);
m_vidoHold.m_media.Play();
}
CATCH (COleDispatchException ,e)
{
// AfxMessageBox("格式不对!或不支持此文件");
}
END_CATCH
