Re: Get folder (not file), then read all files from folder?



To the extent that Navigation Services uses Apple Events,
you can rely on automatic translation to the FSRef data type.

For example, in NavReplyRecord the "selection" part is an
AEDescList.  You can call AEGetNthDesc() with typeFSRef and
pass an FSRef structure instead.

For instance:
FSRef saveDirectory;
AEDesc resultDesc;
AEKeyword keyword;


// figure out what directory the file belongs in
result = AEGetNthDesc(&replyRecord.selection, 1, typeFSRef, &keyword, &resultDesc);
if (noErr == result)
{
result = AEGetDescData(&resultDesc, &saveDirectory, sizeof(saveDirectory));
AEDisposeDesc(&resultDesc);
}
. . .




For general stuff you can look here:
    http://developer.apple.com/documentation/Carbon/Reference/File_Manager/Reference/reference.html

In that document, many deprecated routines show a pointer
to the replacement.  (Not everything has a replacement.)

I know how to use NavCreateChooseFolderDialog to get a folder and then, with some finangling, construct the generic FSSpec of a file in that that folder.

FSSpecs have been deprecated for a long time. You should be working with FSRefs at this point.


I don't even know how to get started updating my file-handling skills. Do FSRefs work with the Nav routines, which seem to operate on FSSpecs, or do I have to use a completely different set of routines for presenting file opening/saving dialogs?

Is this where I should be looking?

http://developer.apple.com/documentation/Carbon/Conceptual/ProvidingNavigationDialogs/nsx_tasks/chapter_3_section_1.html

It's all Nav stuff, FSSpecs and such. The webpages don't have the yellow deprecated message that some documentation pages have.

I just don't even know where to start with this.  If I got here:

http://developer.apple.com/documentation/Carbon/

and select File Management, I don't see a single over-arching "here's how to start learning the new nondeprecated methods" documentation. What I do see, third in the list, is the link to the Nav routines, without a deprecation message, which teaches file management using FSSpecs, as I showed above.

Help.

Thanks.
