IDirectInputEffect::Download

The IDirectinputEffect::Download method places the effect on the device. If the effect is already on the device, the existing effect is updated to match the values set by the IDirectInputEffect::SetParameters method.

HRESULT Download(void);

Parameters

None.

Return Values

If the method succeeds, the return value is DI_OK or S_FALSE.

If the method fails, the return value can be one of the following error values:

DIERR_NOTINITIALIZED
DIERR_DEVICEFULL
DIERR_INCOMPLETEEFFECT
DIERR_INPUTLOST
DIERR_NOTEXCLUSIVEACQUIRED
DIERR_INVALIDPARAM
DIERR_EFFECTPLAYING

If the method returns S_FALSE, the effect has already been downloaded to the device.
