CONST_DIEPFLAGS

Members of the CONST_DIEPFLAGS enumeration are passed to the DirectInputEffect.SetParameters method in order to specify which parameters are being set, and the subsequent behavior of the effect. Some members are also returned by the DirectInputEnumEffects.GetStaticParams and DirectInputEnumEffects.GetDynamicParams methods, giving information about support for the parameter.

DIEP_ALLPARAMS

Not used.

DIEP_AXES

Not used.

DIEP_DIRECTION

The x and y members of DIEFFECT are valid, or the direction parameter is supported. If you are setting or requesting effect parameters, you can specify that the direction is supplied or is to be returned in either Cartesian or polar coordinates by specifying DIEFF_CARTESIAN or DIEFF_POLAR in DIEFFECT.lFlags.

DIEP_DURATION

The lDuration member of DIEFFECT is valid, or the effect supports changing of the duration.

DIEP_ENVELOPE

The envelope member of DIEFFECT is valid, or the effect supports the application of an envelope.

DIEP_GAIN

The lGain member is valid, or the effect supports the application of gain.

DIEP_NODOWNLOAD

After setting parameters, the effect is not to be downloaded.

DIEP_NORESTART

Suppress the stopping and restarting of the effect in order to change parameters.

DIEP_SAMPLEPERIOD

The lSamplePeriod member is valid.

DIEP_START

After setting parameters, start the effect immediately.

DIEP_TRIGGERBUTTON

The lTriggerButton member is valid, or the effect supports a trigger button.

DIEP_TRIGGERREPEATINTERVAL

The lTriggerRepeatInterval member is valid, or the effect supports trigger repeat.

DIEP_TYPESPECIFICPARAMS

The effect has type-specific parameters that can be changed by the application. This value is returned by GetStaticParams for all standard effects and for hardware-specific effects with application-modifiable parameters. DirectX for Visual Basic supports hardware effects only if they do not have this flag set.
