Executing TU client exe from the command line

[Ninj]

Hi,

In TUv1 there is a command line option, /S:#, which can be used to run true update client through the command line where # signifies the screens that will be shown.

Is there any equivalent for this command line option in TUv2? The help file shows only 2 options, the /DATFILE:<<Filename>> and /T:<<FilePath>>.

thanks,

Ninj

You can parse the command line yourself.

I made it so that i have the option "/HIDE" on the command line to not show the screens unless there is an update available.

Then when the update.exe is called implictly I execute it with a /HIDE parameter and does not display unless an update is available. When it is called say from the menu option it has no additional parameter and displays all the screens.

Here are some sections of the Client Script (basically merged from the silent install example and the code that was already there)

g_SilentUntilUpdateAvailable = false;

for idx, sArg in _CommandLineArgs do

  if( sArg == "/HIDE" ) then
    g_SilentUntilUpdateAvailable = true;
  end 
	
end

followed by

if(g_SilentUntilUpdateAvailable) then

  -- Get the list of TrueUpdate Servers
  tableTrueUpdateServers = TrueUpdate.GetUpdateServerList();
  if(tableTrueUpdateServers) then

    -- Loop through the list of TrueUpdate Servers
    for index, ServerName in tableTrueUpdateServers do

      -- Attempt to download the server configuration files
      GotServerFiles = TrueUpdate.GetServerFile(ServerName, false);

      -- If the download was successful, run the server script
      if(GotServerFiles) then
        TrueUpdate.RunScript("Server Script");
        break;
      end
    end
  end

else

  if( not _ClientRestarted ) then
    Result = Screen.Show("Startup");
  end

  if(Screen.Show("Connect to Server") == SR_SUCCESS) then
    TrueUpdate.RunScript("Server Script");
  end
end

There is one additional area you may want to add in the Server script in the case of an error in the confuration. Basically is is along the lines of

if(not g_SilentUntilUpdateAvailable) then
  Screen.Show("Update Actions Failed");		
end

Of course there is nothing limiting the arguments you use or the effect they have. I just used this to emulate the way i used the command line argument /S:# from TU1.

Hope this helps

Hi Steven,

It does make a lot of sense. Thanks!
