Re: printing digest, Vol 1 #244 - 2 msgs: getting the value of installable options in a PDE (Hans Loonen)

Hi,

Here is just a reminder that I did not get a reaction to my problem yet.
I spent another half a day to figure out how to obtain information about
what installable options a user has set in a PDE but I don't get any
further.
E.g. I looked in the Core technologies documentation "getting a ticket
reference" and I used the PMSessionGetDataFromSession function as described:

void describe255(CFTypeRef tested)
{
char buffer[256];
SInt32 got;
CFStringRef description = CFCopyDescription(tested);
CFStringGetBytes(description, CFRangeMake(0,
CFStringGetLength(description)),
CFStringGetSystemEncoding(), '?', TRUE, buffer, 255, &got);
buffer[got]=(char)0;
VERBOSE("describe255: %s", buffer);
CFRelease(description);
}

OSStatus SyncPaneFromTicket(PMPDEContext context, PMPrintSession
printSession)
{
CFTypeRef mydata;
PMSessionGetDataFromSession(printSession, kPDE_PMPrintSettingsRef ,
&mydata);
describe255(mydata);

The result from the debugger is:
VERBOSE: [06/10/2003 16:21:05] describe255: <CFNumber 0x16be050
[0xa01303fc]>{value = +24602144, type = kCFNumberSInt32Type}

What does this mean???

Who has any experience with this and can help me?

Hans
