How to get msiexec.exe command line options within custom dll ?

[Polaris]

Hi Experts:

Searched hours but could not find answer, so I have to try here:

I have a dll for the Custom Action, just wonder how can I get the command
line parameters (like /q or /passive) within my dll ? I guess I should use
MsiGetProperty, but what should I use for the property name?

Thanks!

You will need to use MsiGetProperty, and grab that property that the command
line option maps to.
for example, /q is the user interface level, so you need to lookup the
"UILevel" property

Thanks for your help.

Looks like it works if I set CustomActionData to [UILevel] and then call
MsiGetProperty (.., "CustomActionData"...).

It did not work if I simply do this: MsiGetProperty (..., "UILevel", ...).
It's a bit strange.

Most properties cannot be read in deferred custom actions.
