[Visual Basic]

control.PlayListAddItemEx (

nPlayer as Integer,

strPathname as String,

nIndex as Integer,

nItemType as enumPlayListItemType

) as enumErrorCodes


 

[C++]

short control.PlayListAddItemEx (

Parameter

Description

 

 

nPlayer

Number representing the zero-based index of the player that owns the playlist

strPathname

String containing the absolute pathname of the element to add.

 

If the playlist has been loaded or created with volume automation enabled, you can add a new item containing all the needed mixing positions, volume automation points and cue points in one single shot by passing a well formatted XML string to this parameter; an example of well formatted string is the following:

 

 <Item pathname="C:\sounds\drumtrik01_120bpm.wav" DurationSec="16.00" StartPosSec="2.0" MixPosSec="12.0" EndPosSec="16.0" >

   <VolumePoints>

     <VolumePoint name="start fade-in" VolumeLevelLinear="0.0" PosSec="2.0" CurveType="5"

                LeftX="11" LeftY="3" RightX="93" RightY="43" />

     <VolumePoint name="end fade-in" VolumeLevelLinear="100.0" PosSec="5.5" CurveType="0" />

     <VolumePoint name="start fade-out" VolumeLevelLinear="100.0" PosSec="11.9" CurveType="5"

                LeftX="83" LeftY="13" RightX="32" RightY="41" />

     <VolumePoint name="end fade-out" VolumeLevelLinear="0.0" PosSec="15.9" CurveType="0" />

   </VolumePoints>

   <CuePoints>

     <CuePoint name="Silence end" PosMs="1000" />

     <CuePoint name="Fading point" PosMs="12000" />

     <CuePoint name="Silence start" PosMs="15900" />

   </CuePoints>

 </Item>

 

For details about XML syntax of the string above refer to the How to manage Volume Automation tutorial.

 

If the playlist has been loaded or created without volume automation enabled, you can add a new encrypted item by passing a well formatted XML string to this parameter; an example of well formatted string is the following:

 

 <Item pathname="C:\sounds\drumtrik01_120bpm.wav" DecryptKey="JHDG78TR45JHGaf654MAAKHNF235TY" />

 

nIndex

Number representing the zero-based insertion position: if the nIndex parameter value exceed the playlist length, the song will be placed at the bottom of the playlist

nItemType

Type of item to add
