How to change the layer of Annotations using API?

Hi all,

Below is the code for Changing Layer of dimensions using API.I tried to tweak the below code so that I can create a code for changing the layer of annotations.But, all my trials were failure.As I am new to API, I cant understand its flow and root. Please help me in tweaking  for changing layer of annotations.

Const ToLayer               As String = "FORMAT"

Sub main()
    Dim swApp                   As SldWorks.SldWorks
    Dim swModel                 As SldWorks.ModelDoc2
    Dim swDraw                  As SldWorks.DrawingDoc
    Dim swView                  As SldWorks.View
    Dim swAnn                   As SldWorks.Annotation
    Dim swDispDim               As SldWorks.DisplayDimension
    Dim NumShts                 As Long
    Dim i                       As Long
   
    Set swApp = CreateObject("SldWorks.Application")
    Set swModel = swApp.ActiveDoc
    Set swDraw = swModel
   
    NumShts = swDraw.GetSheetCount
    For i = 1 To NumShts
        swDraw.SheetPrevious
    Next i
   
    For i = 1 To NumShts
        Set swView = swDraw.GetFirstView
        While Not swView Is Nothing
            Set swDispDim = swView.GetFirstDisplayDimension5
            While Not swDispDim Is Nothing
                Set swAnn = swDispDim.GetAnnotation
               
                swAnn.Layer = ToLayer
                Debug.Print "Layer is " & swAnn.Layer
               
                Set swDispDim = swDispDim.GetNext5
            Wend
           
            Set swView = swView.GetNextView
        Wend
       
        swDraw.SheetNext
    Next i
End Sub

Thanks,
