[wix-users] ExecuteFileInUse

[Parkes, Kevin]

No, no record size info. ExecuteFilesInUseEventArgs includes PackageId (string) and a list of strings called "Files" (which aren't actually file names). Currently I am essentially ignoring every other call to ExecuteFilesInUse. It seems to work; hopefully it's good enough.

A couple of follow-up questions:
1) if I allow the user to "ignore", uninstall continues, apparently successfully, but presumably a reboot is required? or advisable? How would I initiate a reboot (I've tried setting the event args Result field to Result.Restart but it seems to have no effect.)
2) how should I handle files in use if running with /quiet or /passive: ignore or abort? (and if ignore, should I reboot, as above?)

Thanks
Kev

I remember dealing with the spurious FilesInUse record in an external record handler. The spurious half-empty record has a data size of zero - that's how I filtered it out. Each in-use entry in a formatted record has two size fields. If the first of these is zero then skip over it because it's not relevant. I haven't looked at the WiX handling of these records but if there's any record size info passed to your code then see if there are any zero values.

I handled similar issue in my MBA where Bundle was uninstalled while main application was running and it uninstalled successfully. So team asked me to check if main application is running. To achieve this, in my Wix markup, I added a C# custom action to check if MainApp.exe is running and so prompt user to close it or cancel installation.
 <Custom Action="CloseAppsPrompt" After="CostFinalize"/>

But never tried to capture FileInUse in MBA....
