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.

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.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
