Getting Data?

[<ABX]

I have a IntPtr that points to a byte array in unmanaged memory.

How can i copy this to a managed byte array or structure?

you probably need to look up Marshal attributes . PtrToStructure is what you're looking for *maybe* .

ok, heres the structure

<StructLayout(LayoutKind.Sequential)> _
    Public Structure TOC
        <MarshalAs(UnmanagedType.ByValArray, SizeConst:=2)> _
        Dim TOC_LEN() As Byte
        Dim FirstTrack As Byte
        Dim LastTrack As Byte
        <MarshalAs(UnmanagedType.ByValArray, SizeConst:=800)> _
        Dim TrackInfo() As Byte
    End Structure

'Heres where the buffer is allocated
 
        Dim xTOC as new TOC
 
        Dim memptr As IntPtr = Marshal.AllocCoTaskMem(Marshal.SizeOf(xToc))
 
        Marshal.StructureToPtr(xToc, memptr, False)
'This is now passed to a api call to be filled

'Heres where i try to read the data the was put intot the structure by the api call
 
            Dim Data As TOC = CType(Marshal.PtrToStructure(psrb.SRB_BufPointer, GetType(TOC)), TOC)
 
'none of the values in data are set???
