The only thing you can do is compare the current value of the property against the known default value. If the command-line value is the same as the default value you wouldn't ever be able to know.
The only way to know for sure if a property was set from the command-line is to not have the property in the Property table at all and to assign it its default value from some sort of custom action. -----Original Message----- From: Alex Ivanoff [mailto:alex.ivan...@shavlik.com] Sent: Sunday, January 03, 2010 10:24 PM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Overwrite property only if it was not set on command line I have a property that has a default value. I want to change this property in custom action only if this property was not set on command line.
