[WiX-devs] SetExternalUI - Multiple InstallLogModes

[Lewis99 <and...@gm...>]

Hello,

Apologies if this is a basic question as I am quite new to both C# and DTF.

I am trying to put a test application together to silently run MSI's and
test Custom Actions that are kicked off within them. I am setting the MSI
User Interface to Silent and attempting to add my own handler for the
messages coming in.

The method signature for SetExternalUI is as follows: 
public static ExternalUIHandler SetExternalUI(
	ExternalUIHandler uiHandler,
	InstallLogModes messageFilter

How can I specify more than one InstallLogMode to ensure that all the
necessary messages are handled by my user interface?

At the moment I can only specify one. In reality I need an enum value
something like this: ExternalUI = FatalExit | Error | Warning | User |
ActionStart | ActionData | CommonData | Progress | ShowDialog.

Is there a way to do this with the existing enum or by using the
ExternalUIHandler differently? Here is my existing code:

private void RunInstall(string PathToMSI, string CommandLineArguments)
{
      try
      {
        Installer.SetInternalUI(InstallUIOptions.Silent, ref parent);

        ExternalUIHandler handler = new
ExternalUIHandler(ActionStartHandler);
        ExternalUIHandler result = Installer.SetExternalUI(handler,
InstallLogModes.ActionData); // can only specify one mode

        Session session = Installer.OpenPackage(PathToMSI, false);
        //session.DoActionSequence("InstallUISequence");
        session.DoActionSequence("InstallExecuteSequence");
        session.Close();
      }
      catch (Exception e)
      {
        Debug.WriteLine("EXCEPTION -- " + e.ToString());
      }
}

public MessageResult ActionStartHandler(InstallMessage MessageType, string
Message, MessageBoxButtons Buttons,
MessageBoxIcon Icons, MessageBoxDefaultButton DefaultButton)
{
      switch (MessageType)
      {
        case InstallMessage.ActionStart:
          ChangeListViewProperly(Message + " " +
DateTime.Now.ToString("dd/MM/yyyy HH:mm:fffff"));
          break;
        case InstallMessage.ActionData:
          ChangeListViewProperly(Message + " " +
DateTime.Now.ToString("dd/MM/yyyy HH:mm:fffff"));
          break;
      }

      return MessageResult.OK;
}

Thanks in advance for your help.
Lewis
