G'day People,
Well, Wit's End is looming fast on the horizon. I have been trying
a (seemingly) simple task and have been failing dismally. I want to set
the default volume and directory using a 'STR ' resource containing the
full pathname.
I've read most of IM IV Ch 14, and IM II Ch 4 but they have
provided no joy.
Extracting the 'STR ' stuff was a gimmie, I have the Pascal format
string stored in a Str255 waiting to be used. The string is of the format
'DriveName:FolderName' I have tried numerous calls to SetVol and PBHSetVol,
none of which to do any good, but return noErr.
What's the answer? I'm reasonably sure it's pretty trivial, but I
have been unable to track down what I am doing wrong.
On a similar vein, how can I use BootDrive to set the volume to
that 'value'.
Yours in much confusion.

Try: var aStr:StringHandle; begin aStr:=GetString(stringID); if aStr<>nil then begin if SetVol(aStr^,0)=noErr then begin ... end else error end else error end; If this doesn't work, try taking a colon on the end of the STR in your resource file. Perhaps you're being bitten by an assumption that got me the first time I tried this. The default directory is *not* the directory which appears by default when you do SFGetFile or SFPutFile. There are low-memory globals which deal with this; ask for details if this is the case. > Jon Eaves -- +-------------------+-jackiw@cs.swarthmore.edu / !rutgers!bpa!swatsun!jackiw-+ | nicholas jackiw | jackiw%campus.swarthmore.edu@swarthmr.bitnet | +-------------------+-VGP/MathDept/Swarthmore College, Swarthmore, PA 19081--+ "Ah...I've got this CHRONIC pain." _True Believer_

AAAARGH, This is what I want. I want SFGetFile to open up on a specific folder. I presumed (incorrectly obviously) that they opened up to the default directory. How do I set this up then? > +-------------------+-jackiw@cs.swarthmore.edu / !rutgers!bpa!swatsun!jackiw-+ > | nicholas jackiw | jackiw%campus.swarthmore.edu@swarthmr.bitnet | > +-------------------+-VGP/MathDept/Swarthmore College, Swarthmore, PA 19081--+ -------------------------------------------------------------------------------- Jon Eaves Whatever you do, don't mention the war. - Basil Fawlty.

Set CurDirStore to the directory ID of the folder you want to open (2 for the root), and set SFSaveDisk to the NEGATIVE of the VREFNUM (not WDRefNum) of the volume the folder is on. CurDirStore = $0398 (long) SFSaveDisk = $0214 (word) (BTW, in later versions of MultiFinder, these globals are application-specific, so each application has it's own CurDirStore and SFSaveDisk) -- Matthew T.

Without going into TOO much detail, I believe you want to create a new working directory ID and then do a SetVol to that ID. Look at the section titled Working Directory Routines starting in IM IV-158. Also, pages IV-98 and IV-100 have interesting and pertinent information. If you need more info, send me email.
