In article <419@lloyd.camex.uucp> I write: >About *my* recent question of how to find out the directory of the >currently selected file in SFGetFile at hook time. Yes, -1 * >SFSaveDisk is the volume and CirDirStore is the dirID. That works. >What I don't know is a good way to get from there to opening the >currently selected file with OpenResFile. I figured it out. Turns out to be easy. PBHSetVol was the answer. Call GetVol and remember the result, stuff a WDPBRec parameter block, call PBHSetVol, call OpenResFile, call SetVol to restore the remembered value (see Tech Note 140). Other than a random set of illegal instruction bombs, it works. (Must dig about looking for uninitialized thingies.) I never did figure out why my sequence of calls to SetVol didn't do it--I don't really know what SetVol is supposed to do and Inside Macintosh is very terse on the subject--but I do know a lot more about HFS now.
