Parameter

Description

nPlayer

Number representing the zero-based index of the involved player.

nItem

Number representing the zero-based index of the item inside the playlist. The number of available items can be obtained using the PlayListGetCount method.

strVolumePointName

String representing the friendly name of the volume point to modify

nPositionUnit

The unit used to define positions of volume points.

Supported values are the following:

fPosition

Reference that, on return from the method call, will contain the position of the volume point expressed in the same unit set into the nPositionUnit parameter.

nVolumeScaleType

The volume scaling type.

Supported values are the following:

fVolumeLevel

Reference that, on return from the method call, will contain the volume level expressed in the same unit set into the nVolumeScaleType parameter.

nCurveType

Reference that, on return from the method call, will contain the type of curve applied to reach the next volume point.

Set this parameter to -1 if you need to leave the current curve type unchanged.

Supported values are the following:

nLeftX

Reference that, on return from the method call, will contain the horizontal position, expressed in percentage of the designer's area, of the left control point. This parameter can be ignored when the nCurveType parameter above is set to a value different from VOLUME_CURVE_CUSTOM.

nLeftY

Reference that, on return from the method call, will contain the vertical position, expressed in percentage of the designer's area, of the left control point. This parameter can be ignored when the nCurveType parameter above is set to a value different from VOLUME_CURVE_CUSTOM.

nRightX

Reference that, on return from the method call, will contain the horizontal position, expressed in percentage  of the designer's area, of the right control point. This parameter can be ignored when the nCurveType parameter above is set to a value different from VOLUME_CURVE_CUSTOM.

nRightY

Reference that, on return from the method call, will contain the vertical position, expressed in percentage of the designer's area, of the right control point This parameter can be ignored when the nCurveType parameter above is set to a value different from VOLUME_CURVE_CUSTOM.

Value

Meaning

enumErrorCodes.NOERROR (0)

The method call was successful

Negative value

An error occurred: see the LastError property for further error details or for a list of the possible error values.
