CopyMemory problem

[Mr.Fixit]

'Declare types and functions
Option Explicit
 
Type SAFEARRAYBOUND
    cElements As Long
    lLbound As Long
End Type
 
Type SAFEARRAY2D
    cDims As Integer
    fFeatures As Integer
    cbElements As Long
    cLocks As Long
    pvData As Long
    Bounds(0 To 1) As SAFEARRAYBOUND
End Type
 
Declare Function VarPtrArray Lib "msvbvm50.dll" Alias "VarPtr" (Ptr() As Any) As Long
Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (pDst As Any, pSrc As Any, ByVal ByteLen As Long)
 
'Declare   vars
Public pic() As Byte
Public sa As SAFEARRAY2D
 
'in a Button_Press Sub:
CopyMemory ByVal VarPtrArray(pic), VarPtrArray(sa), 4

Im getting the error:
"Compile Error
Type mismatch: array or user defined type expected"

after i press OK the variable sa is highlighted from the line
CopyMemory ByVal VarPtrArray(pic), VarPtrArray(sa), 4

anyone have any ideas?
