Im having difficulty implementing the transfer function... Works Fine when I give _launch the full pathname of the application to launch but when I get the file name from SFGetFile tack a ':' onto the front of it and then call PBOpenWD (which returns with no err condition) with: pb.ioWDDirID = CurDirStore pb.ioRefNum = SFReply.vRefNum pb.ioWDProcID = my application's signature Launch still gives me the Application missing dialog box as if I hadn't. Changed directories at all.. What am I missing? Any better Ideas all together on how to implement this? Is there any function hidden in IM somplace that returns a full path name given an SFReply? Somebody care to help a lost soul?

You need to not only open the directory, you need to SetVol to it. -- Matthew T. Russotto russotto@eng.umd.edu russotto@wam.umd.edu ][, ][+, ///, ///+, //e, //c, IIGS, //c+ --- Any questions?

There is no toolbox routine to return a full path name, but doing it
yourself is fairly easy.
Here is a C routine to do it (gleaned from some DTS sample code)...
/*
**pathName (dirID,vRefNum,s)
**returns a string containing the full pathname to the current file or
directory
**this code is snached from the DTS sample code StdFile.c (but slightly
modified).
**Added support for both files and directories. Don't give a flying *#@!
if it
**breaks under A/UX, thank you very much....
*/
char *pathName(dirID,vRefNum,s)
long dirID;
short vRefNum;
char *s;
{
OSErr err; /* error container */
CInfoPBRec block; /* infoBlock to be used CatInfo calls */
Str255 directoryName; /* a place to stuff my directory name */
*s = 0;
block.dirInfo.ioNamePtr = &directoryName;
block.dirInfo.ioDrParID = dirID;
do {
block.dirInfo.ioFDirIndex = -1; /* Specify vRefNum and DirID for call */
block.dirInfo.ioVRefNum = vRefNum; /* set the ParamBlock's vRefNum */
block.dirInfo.ioDrDirID = block.dirInfo.ioDrParID; /* set the ParamBlock's
DirID */
err = PBGetCatInfo (&block,false);/* get information on catalogue */
if (err) break;/* get me outta here...... */
pStrcat (&directoryName,"\p:");/* add a colon to the begining... */
pStrcat (&directoryName,s);/* prepose newly found directory name */
pStrcpy (s,&directoryName);/* swap the two */
} while (block.dirInfo.ioDrDirID != fsRtDirID);/* loop till we hit the
root */
return (s);/* cough up the result */
}
Hope that was helpfull.

Here is the same thing (I think) that I use short constructPath(cRecPtr,pathName,dirID) CInfoPBRec *cRecPtr; char *pathName; long dirID; { char buffer[32]; short error; if (dirID == 1) return(0); cRecPtr->dirInfo.ioDrDirID = dirID; cRecPtr->dirInfo.ioNamePtr = buffer; cRecPtr->dirInfo.ioFDirIndex = -1; if (error = PBGetCatInfo(cRecPtr,false)) return(error); if (error = constructPath(cRecPtr,pathName,cRecPtr->dirInfo.ioDrParID)) return(error); BlockMove(&(buffer[1]),&(pathName[pathName[0]+1]),buffer[0]); pathName[0] += buffer[0]; pathName[++pathName[0]] = ':'; return(0); } It basically stacks all the names as it follows up to the root, and copies on the way back down. Interesting, I thought (when I think). >Neil Day Brian Topping <topping@cis.ohio-state.edu>
