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.

Subject: [WiX-users] Update InstallExecuteSequence Condition Programmatically
using DTF
I’d like to write a program using DTF to open up a MSI package and
programmatically update some Conditions in the InstallExecuteSequence table.
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.
