I strongly recommend you read the File Server chapter in Symbian OS Internals. Your PXT is loaded into the fileserver process. There is a seperate client side plugin that is loaded into your process...

This question is very interesting since you cannot use or even run UI applications with TCB capability. TCB is reserved for a small set of applications and pxt's would be an overkill in most cases....

You would need to raise this through the partnering process as this API is not public.

We also tried as a 3rd party company to get access to the API and it was rejected.

You should probably post the code, my guess is you are using a TInt and not a TInt32 which seems to have issues with the way c++ handles overloading of types.

Anyway I fail to see why it is so vital that the phone is not switched off, so you probably need to tell us what you really want to do.

In many countries it would also be illegal as some places (such as aircraft and hospitals) prohibit the use of electronic equipment.

This depends on two factors.

The first is the device class - you can learn more about the GSM device classes here (http://en.wikipedia.org/wiki/General_Packet_Radio_Service)

The second is...

FWIW the panic code is ESWInstPanicBadHandle which means there is no session connected

Enable extended error logging to find out why - something obviously happened or you did not run the program

Security is per process so your dll can call into a tcb process via IPC since the server...

I believe there is an implementation but only for 5th edition and later devices (basically you need the 9.4 devkit) which had it in it. Its not supported on earlier versions.

You could use the...

You define the SID using the AVKON_SOUND_INFO structure in the rss file

Since the file is reported as not found in the emulator it is probably not there.
Did you look in your <sdk path>\epoc32\release\winscw\udeb\z\resource\plugins folder to view whether or not it...

Anything that will be using the UI basically.

RFile newfile_upload;
RFs ifsession;
User::LeaveIfError(ifsession.Connect());
TInt err = newfile_upload.Open(ifsession, afilepath, EFileRead);
CleanupClosePushL(newfile_upload);
if(err!=...

The simplest solution might just be to add a method called for example "Shutdown" to the API and use that to release the resources. then disconnect need not do anything

There are set methods in the CRepository class.

See CS000953 - http://wiki.forum.nokia.com/index.php/CS000953_-_Using_customized_key_sounds_with_CAknKeySoundSystem

You need to use the SyncML API's in FP2 and later, I think they are in the partnering SDK, if not you will need to open a support and partnering request with Nokia to get them. ( I can't remember...

I don't have any I can publicly show.

Basically you create a new rss file and add it to the mmp file as a resource type (like the other rss files)
This will then create the rsc and rsg files.
...

Use CCoeEnv::AddResourceFileL to add the resource file to the current process and then the resource will be avaliable to the dll.
Note that the name field of the resource file (the first line of...

Use elftran on the exe to dump the header info which will tell you the capabilities of the exe

Check further, its part of the movino project

Or you could use a mutex which is shared across process to sequence operations

IIRC the hashmap API's are in there from the MR release, it was just that someone omitted the header files from the S60 SDK (They were in the orignal Symbian BAK's) so I suggest you try some basic...
