Custom Actions for IIS installation - ComboxBox Empty Issue
I'm following a number of different tutorials in an attempt to make a generic IIS WIX installer which I can then split up as 开发者_JAVA百科appropriate into different libraries.
Tutorials
creating a web application installer with wix 3.5 and visual studio 2010 (Paul Reynolds blog)
Creating WIX Installer for ASP.NET Web Application (Code Project)
Web Application Installer in WiX (John Robbins' blog)
So far, I've got an installation that seems to work when run with the /q flag. However in interactive mode, the custom action which is supposed to populate the combo box isn't working.
I've tried to debug but I've come into the following problems:
- Session.Log commands don't seem to output anywhere
- Attaching to msiexec and calling Debugger.Launch or MmsiBreak seem to just exit straight away (even with breakpoints enabled).
Starting to get frustrating as it shouldn't be this difficult to take values from a custom action and pass them into a combo box.
Anybody have any ideas what could be the root cause, I'm expecting a lot of people have either used this code or something similar to it:

using System.Diagnostics;
using System.DirectoryServices;
using System.Globalization;
using System.Linq;

Two quick things:
- I don't see where you're scheduling your action here (just its definition and Binary entry), so I'm not convinced it's being run; the entries in a verbose log could confirm or refute that. Even if it is running...
- Session.Log does not work on an action launched from a dialog (Windows Installer limitations), so even if this is running it won't say more than that the action was launched. One common workaround is to ensure you're logging property changes, and change a property:
Session["LOGHACK"] = message;
