Mac Forum / Programming / CodeWarrior / April 2005Dumb open file problem
Hi folks, I'm working on a test app that needs to be able to open any text file, regardless of creator, as it's a prototype for a cross-platform program. I'm using Nav Services (via Power Plant) and have set up the creator code as '????' and the file type as 'TEXT', and this seems to work fine. However I've been sent some Windows files that I need to open, which arrived with a strange extension which made the system think they were Unix executables?!? I changed the extension to .txt and they now show up as plain text documents with Get Info, however the app still won't open them. I can open them with the IDE, but as they contain some binary data the IDE 'corrects' them and changes the contents. If I remove the binary data and save them in the IDE they show up in my app's open file dialog. I've tried setting the Nav Services signature to kNavGenericSignature but to no avail. Any suggestions?

It is used by Launch Services, and hence the Finder to know what kinds of files are legal to drop on your application icon. See the tech note on 'plst' 0 resources on developer.apple.com for more information about that. For Nav Services filtering, if you can't trust the OSType file type, then you'll have to have Nav Services call your filter function, which is allowed to open the file and read the first few 100 bytes to determine if it should enable the item in the Nav Services dialog. How are you 'open' and 'kind' resources set up? What are you actually passing to Nav Services? You seem to misunderstand what the Nav Services "signature" is for. You might want to recheck the documentation on this.  SignatureDavid Phillip Oster |
