[2005]Expected Expression on ByVal 0&

I'm converting some code from VB6 to .NET (2005) but it didn't manage to handle everything in the autoconvert. Now I have a few errors left in this code:

Code:

---

Private Declare Function ReadFile _
  Lib "kernel32" ( _
  ByVal hFile As Long, _
  ByVal lpBuffer As Object, _
  ByVal nNumberOfBytesToRead As Long, _
  ByVal lpNumberOfBytesRead As Long, _
  ByVal lpOverlapped As Object) As Long


      Do
        ' Add a DoEvents to allow more data to be written to the buffer for each call.
        ' This results in fewer, larger chunks to be read.
        'DoEvents

            If ReadFile(hPipeRead, baOutput(0), BUFSIZE, lBytesRead, ByVal 0&) = 0 Then
          Exit Do
        End If

        If blnOEMConvert Then
          ' convert from "DOS" to "Windows" characters
          sNewOutput = CChar(CChar(CStr(lBytesRead)))
          Call OemToCharBuff(baOutput(0), sNewOutput, lBytesRead)
        Else
          ' perform no conversion (except to Unicode)
          sNewOutput = Left$(StrConv(baOutput(0), 64), lBytesRead)
        End If

        GetCommandOutput = GetCommandOutput & sNewOutput

        ' If you are executing an application that outputs data during a long time,
        ' and don't want to lock up your application, it might be a better idea to
        ' wrap this code in a class module in an ActiveX EXE and execute it asynchronously.
        ' Then you can raise an event here each time more data is available.
        'RaiseEvent OutputAvailabele(sNewOutput)
      Loop

The stuff in magenta is giving errors. I am not sure what to do about the ByVal 0& stuff.

API functions in .NET need to be changed a bit from VB6.

try using this as your API dec

Code:

---

<DllImport("kernel32.dll")> Friend Shared Function ReadFile( _
    ByVal File As SafeFileHandle, _
    ByVal Buffer As System.Text.StringBuilder, _
    ByVal NumberOfBytesToRead As Integer, _
    ByRef NumberOfBytesRead As Integer, _
    ByRef Overlapped As System.Threading.NativeOverlapped) As SafeFileHandle
End Function

---

and then changing where you call it to match these new params.

Also I am not sure what your code does, but the .NET framework has LOADS of file IO functions built right in that were pretty much non existant in VB6.
