Generally. I'll avoid details about what methods to call and stuff and give you more high level advice.
I've found it useful to design code like this to be driven off of XML. For example I might right something like <ActionRef Id="ActionICareAbout" Condition="MyNewCondition"/> This allows me to write methods that do the work and methods that parse the XML and call the first methods. It's almost like creating my own DSL and it's very scalable. In fact much of my work involves parsing WiX fragments and calling into InstallShield automation to build up projects. Or if you only have a few things you need to do the above element could also be used to generate a simple update statement.

This program be used to update MSI packages before installation. Here’s some pseudo code for what I have so far: using (database = new Database(filePath, DatabaseOpenMode.Transact)) { query = database.Tables["InstallExecuteSequence"].SqlSelectString using (view = database.OpenView(query)) { while (record = view.Fetch()) { try { action = record.GetString("Action") if (action is the action I want) { record.SetString("Condition", "new condition") } } finally { record.Close() } } } database.Commit() } I’m trying to implement this as a PowerShell script so my script doesn’t look exactly like the pseudo code above. Is this going in the correct direction? I have a feeling that this isn’t quite right but I don’t know exactly what the missing piece is. Edwin G.
