Hi all,

I've been trying to get a set of custom strings in to the Format popup of a

save dialog created with NavCreatePutFileDialog. I've done a bunch of

searches to find sample code on this as the API documentation seems sparse,

but everything I try ends up with the application crashing when I call my

dialog. My most recent search suggested a simple solution from this group:

CFArrayRef myCFArrayRef = NULL;

CFStringRef strs[2];

strs[0] = CFSTR("Standard MIDI file");

strs[1] = CFSTR("Hitlist Document");

myCFArrayRef = CFArrayCreate(NULL,(void *)strs,2,&kCFTypeArrayCallBacks);

dialogOptions.popupExtension = myCFArrayRef;

But even running something as simple as that using

'NavCreatePutFileDialog(&ndcOptions, '/?/?/?', '/?/?/?', NULL, NULL,

&ndrRef);' is causing the app to crash with 'Signal 10'.

I've tried a bunch of other solutions involving creating arrays of various

types of objects and allocating them to that member of the dialog options,

but nothing seems to be working for me. This is with a basic Carbon app,

implemented in main.c with Carbon.h included and nothing else.

Does anyone have any idea what could be going on? I've been tearing my hair

out trying to work out why the varied methods I'm finding out there aren't

working for me and any help would be much appreciated!

Thanks.

- Matt.
