Thanks in Advance,

I don't know if I need to copy the memory to an Array (thats what I
would have done it in vb6), I just need to be able to read/access it.

I have a Callback function that is handing me a block of memory -

Function BufferCB(ByVal SampleTime As Double, ByVal pBuffer As IntPtr,
ByVal BufferLen As Integer) As Integer Implements _ISampleGrabberCB.BufferCB
         SyncLock Me

    Dim BAR() As Byte
    ReDim BAR(BufferLen)    ' This creates the buffer but I need to copy
            ' the data from the memory location in pBuffer                     ' pointer.
    End SyncLock
    Return 0
End Function


Thanks Again.

Check out the members of 'System.Runtime.InteropServices.Marshal'.

Sorted, Thank you.
