If thought that this code would work to tell iTunes to play or pause, but it
doesn't seem to be executing the event, but gives no error on compile and no
problems show up in console. This code is an adaptation from the code that
ClassicSpy uses to send a Quit Event to Classic. I have adapted the daemon
for it so that it has no problems sending a standard Quit Event to iTunes.
AEAddressDesc clasSprt;
AppleEvent anAppleEvent, reply;
if (classicRunning) {
if (AECreateDesc(typeNull, NULL, sizeof(reply), &reply) == noErr) {
if (AECreateDesc('hook', &iTunesPSN, sizeof(ProcessSerialNumber),
&clasSprt) == noErr) {
if (AECreateAppleEvent('hook', 'PIPs', &clasSprt,
kAutoGenerateReturnID, kAnyTransactionID, &anAppleEvent) == noErr) {
// Send the Apple Event.
if(AESend(&anAppleEvent, &reply, kAENoReply, kAENormalPriority,
kAEDefaultTimeout, nil, nil) != noErr)
NSLog(@"iTunes: AESend error");
AEDisposeDesc(&anAppleEvent); // Dispose of the Apple Event.
} //else NSLog(@"AECreateAppleEvent error %d", err);
AEDisposeDesc(&clasSprt);
} //else NSLog(@"AECreateDesc 2 error %d", err);
AEDisposeDesc(&reply);
} //else NSLog(@"AECreateDesc 1 error %d", err);
}
I'm sure the problem is simple, but no examples or reference is telling me
anything as to why this isn't working. Any AppleEvent masters out there to
help me out?
Hello,
I see is two problems here. First is that you don't need to allocate
a descriptor for reply event. It will be allocated by AESend if you
specify that you _ARE_ interested in the reply and you're not
kAENoReply. So the first AECreateDesc is not neccessary. Just use
AEInitializeDesc(&reply) instead. Second thing is that you wrongly
specify the event's target. You should create a AEDesc &clasSprt with
typeProcessSerialNumber and hot type 'hook'. I bet AESend returns
procNotFound (-600) error.
