MFC McISendString specified location play
With the function to send command control designated point location, the player now has a slider with the mouse point to where play
Have know master code
Himself wrote a cannot use
Int nPos=m_slider. GetPos ();
Cstrings step;
Long lPosition;
TCHAR szReturn [MAX_PATH]={0};
LPosition=nPos;
Step. The Format (_T (" seek movie to % ld "), lPosition);
_stprintf (szReturn, _T (" % d "), nPos);
McISendStringW (step, szReturn, MAX_PATH, 0);
Behind the three parameters to zero
