Hello folks,
I've asked this question before and didn't get any answers. Now I have some
specific code that doesn't work, so I thought I'd ask again.
Basically, I want my application to receive the applications beamed to the
device on which it is installed, so that it can inspect them first. So far I've
tried the following:
UInt32 PilotMain (UInt16 cmd, MemPtr cmdPBP, UInt16 launchFlags)
{
switch (cmd)
{
case sysAppLaunchCmdSystemReset:
case sysAppLaunchCmdSyncNotify:
RegisterForNotifications ();
break;
case sysAppLaunchCmdExgReceiveData:
ReceiveDatabase ((ExgSocketPtr) cmdPBP);
break;
default:
break;
}
return 0;
}
That is, on application installation and on reset, I register my application to
receive the applications beamed to the device and when data has been received
by the application, it tries to receive the beamed application.
RegisterForNotifications works does just
void RegisterForNotifications (void)
{
ExgRegisterData (appCreatorID, exgRegExtensionID, "PRC");
ExgRegisterData (appCreatorID, exgRegTypeID,
"application/vnd.palm\tapplication/x-pilot");
ExgSetDefaultApplication (appCreatorID, exgRegExtensionID, "PRC");
ExgSetDefaultApplication (appCreatorID, exgRegTypeID,
"application/vnd.palm\tapplication/x-pilot");
ExgSetDefaultApplication (appCreatorID, exgRegCreatorID, "lnch");
}
where appCreatorID is #defined as the creator ID of my application.
Receiving the beamed application is done like this:
Err ReadDBData (void *dataP, UInt32 *sizeP, void *userDataP)
{
Err err;
*sizeP = ExgReceive ((ExgSocketPtr) userDataP, dataP, *sizeP, &err);
return err;
}
Boolean DeleteProc (const Char *nameP, UInt16 version, UInt16 cardNo, LocalID
dbID, void *userData)
{
return false;
}
Err ReceiveDatabase (ExgSocketPtr exgSocket)
{
LocalID dbID;
Boolean doReset;
Err err;
err = ExgAccept (exgSocket);
if (err == errNone)
{
err = ExgDisconnect (exgSocket, ExgDBRead (ReadDBData, DeleteProc,
exgSocket, &dbID, 0, &doReset, true));
SndPlaySystemSound (sndWarning); // Show that we're alive
// Do something with the received database (referred to by dbID)
}
return err;
}
Yet the above code doesn't work. That is, I don't get any beeps and it is
apparently still the Launcher that is receiving the beamed applications. What
am I missing?
Regards,
Vesselin
