It will require a call to WinAPI Send Message:

Private Declare Function SendMessageAsLong Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Const EM_GETLINECOUNT = 186

Private Function GetLineCount() As Long
   GetLineCount = SendMessageAsLong(RichTextBox1.hWnd, EM_GETLINECOUNT, 0, 0)
End Function

MCix has responded a few seconds before me :

Private Declare Function SendMessageAsLong Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Private Function GetLineCount () as long
      '* This function will return the number of lines in the control
      Const EM_GETLINECOUNT = &H400 + 10      

      GetLineCount = SendMessage(ctrl.hwnd, EM_GETLINECOUNT, 0&,

End Function
