Delphi connection test with TIdFTP

Question

On my program I'm actually using this code:

if IdFTP1.Connect = True then
 begin
  //makes some stuff
 end
else
 begin
  ShowMessage('you got the move like jagger.');
 end;

If I am not connected I see an error like

Socket Error #11001

Host not found

To avoid this, I thought that I could use the code you see above but I am having an error when I use IdFTP1.Connect = True.

What could I do?

Answer 1

Connect() does not return a Boolean if it fails. It raises an exception instead:

try
  IdFTP1.Connect;
  try
    //makes some stuff
  finally
    IdFTP1.Disconnect;
  end;
except
  ShowMessage('you got the move like jagger.');
end;
