MCIWndSetTimeFormat
The MCIWndSetTimeFormat
macro sets the time format of an MCI device. You can use this macro or
explicitly send the MCIWNDM_SETTIMEFORMAT message.
LONG MCIWndSetTimeFormat(
|
hwnd, |
|
|
lp |
|
|
); |
|
Parameters
hwnd
Handle of the
MCIWnd window.
lp
Address of a
buffer containing the null-terminated string indicating the time format.
Specify frames to set the time format to frames, or ms to set the time
format to milliseconds.
Return Values
Returns zero
if successful or an error otherwise.
Remarks
An
application can specify time formats other than frames or milliseconds as long
as the formats are supported by the MCI device. Noncontinuous formats, such as
tracks and SMPTE, can cause the trackbar to behave erratically. For these time
formats, you might want to turn off the toolbar by using the MCIWndChangeStyles macro and specifying the
MCIWNDF_NOPLAYBAR window style.
If you want
to set the time format to frames or milliseconds, you can also use the MCIWndUseFrames
or MCIWndUseTime macro. For a list of time formats, see the MCIWndGetTimeFormat
macro.
