MCIWNDM_PLAYTO  3ECQ_HS 

The MCIWNDM_PLAYTO message plays the content of an MCI device from the current position to the specified ending location or until another command stops playback. If the specified ending location is beyond the end of the content, playback stops at the end of the content. You can send this message explicitly or by using the MCIWndPlayToJN07D3 macro.

MCIWNDM_PLAYTO

wParam = 0;

lParam = (LPARAM) (LONG) lEnd;

Parameters

lEnd

Ending location. The units for the ending location depend on the current time format.

Return Values

Returns zero if successful or an error otherwise.

Remarks

This macro is defined using the MCIWndSeekF.MRCU and MCIWndPlayToJN07D3 macros, which in turn use the MCI_SEEK12F9YYY command and the MCIWNDM_PLAYTO message.

You can also specify both a starting and ending location for playback by using the MCIWndPlayFromTo1NKWDUP macro.
