This would fall into the bucket of "sure, when I have time", but my C++ skills may not be up to the task. Looks like you've got some library functions already written that would make it fairly easy though. If I get to it, I'll contact you about what I need to do to submit the code for inclusion into the project. In the meantime, since it looks like I'll need to rely on a custom action, I can code a DTF custom action to do what I want. As a reminder, I'm wanting to: * Read the user's app.config file, if it has already been installed * Get the settings out of the config file set during the initial installation * Restore those settings to the newly-installed config file Furthermore, I only want to do this in the update, reinstall, or repair case. My code to set the config values during the initial installation works great; I just need to preserve those settings should the user ever repair, reinstall, or apply an update (which I'm implementing as a reinstall with an updated .msi). What I'm looking for is some guidance about how to use my custom action. My instincts tell me to perform a FileSearch for the config file and set a custom property if the file exists; schedule the "harvest settings" custom action before InstallFiles; and within the custom action code, harvest the settings if the custom property is actually set. Are my instincts correct or is there a better way? For my own education about Windows Installer and WiX, I have a few other questions that the SDK docs aren't clear to me on: Should I be trying to conditionally schedule the custom action to only run during reinstall? If so, what properties should I be checking (checking REINSTALLMODE for the value "vomus" seems fragile to me)? How do you conditionally schedule a custom action anyway (neither the CustomAction nor the Custom elements support a Condition element)? ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
