FileExist Check In Use
Keywords: FileExist In USe Readable Writable ExtractAttachedFile
This article being edited.
Question:
My script's installation script bombs out when using ExtractAttachedFile if there's an existing file currently in use. Is there a test I can run prior to ExtractAttachedFile that would allow me to tell the user that file "xyzzy.dll is in use, stop existiing related processes, and try again?" I thought maybe if fileExist("xyzzy.dll") == 2, but that seems to be only for files that can't be read. Apparently fileExist(filename) == 3 is not an option in my version.Answer:
After checking for existence, attempt to open the file for unshared writing. Trap any resulting error.Article ID: W17894
