Most elegant way to check if a network connection is available

• .asim

  If you asking to check that the you have a network connection prior to trying to do a file upload to an FTP

  Using VB.Net 2005 you can use the My Classes.

  The general construct would be something like the following. You simply need to put you filename and URL Address in there which would be you FTP location.

  If My.Computer.Network.IsAvailable Then
  Try
  my.Computer.Network.UploadFile(<FileName>,<Address>)
  Catch ex As Exception

  End Try
  End If

  if you want to check if you can connect to the FTP site, you can use

  if my.computer.network.ping("your.ftp.server") instead of my.computer.network.isavailable above

  I would probably do a combination of both. That is that I wouldnt bother doing a ping if there wasnt any network connectivity as it would probably fail.

  So you check to see that you have a network connection, if you do you ping the ftp server and if you get a positive response then you upload the file to the ftp server.

  
  If My.Computer.Network.IsAvailable Then
  if my.computer.network.ping("your.ftp.server") then
  my.Computer.Network.UploadFile(<FileName>,<Address>)
  end if
  End If
