[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

The put_SuppressEffects method sets preferences for power management and visual effects.

Syntax

HRESULT put_SuppressEffects(
  [in] VARIANT_BOOL bSuppress
);

Parameters

[in] bSuppress

Specifies a Boolean value. See Remarks for more information.

Return value

Returns an HRESULT value. Possible values include the following.

Return code	Description
S_OK	Success.

Remarks

If bSuppress equals VARIANT_TRUE, the Video Control does the following:

Disables font smoothing and the system-wide drop shadow effect. (Only when the Video Control is using hardware overlay.) This is useful if the application draws onto the overlay.
Disables the screen saver, and turns off power management for the display. This is useful to prevent the operating system from interrupting playback while the user is watching a program.

The Video Control restores the original system settings after it stops.

If bSuppress equals VARIANT_FALSE, the Video Control uses the existing system settings.

Requirements
