Hello everybody,
I'm developing an application (EXE) and I have a problem with RunApplication method.
This is part of my code:

LOCAL_C CApaApplication* NewApplication()
{
    return new CIMClientApp;
}

GLDEF_C TInt E32Main()
{
    return EikStart::RunApplication( NewApplication );
}

where CIMClientApp is a subclass of CAknApplication.

The method EikStart::RunApplication() makes the application and the emulator crash badly. Method NewApplication() is not executed, because crash occurs before its execution.
Running the debugger (I'm using Carbide.c++) and catching any cpu exception, I get this stack trace:

Re: [Noob] - EikStart::RunApplication() makes the emulator crash

Ok I solved the problem, unchecking '0xE06D7363' under Debug Dialog->x86 Exceptions.
I discovered that this exception occurred during the emulator startup (after some seconds), so before executing application code.
Now the emulator starts correctly, but when RunApplication() is executed everything crashes again...
This is the last console output, (unfortunately I can't get any stack trace):

Re: [Noob] - EikStart::RunApplication() makes the emulator crash

-1 is KErrNotFound.

Possibly you have some problem with application resources missing that the app framework try to load.

Re: [Noob] - EikStart::RunApplication() makes the emulator crash

I'd guess that your resource file is broken. Check that all your resources are after RSS_SIGNATURE (must be first), RESOURCE TBUF r_default_document_name and EIK_APP_INFO.

Re: [Noob] - EikStart::RunApplication() makes the emulator crash

Thanks for replies. I think you are right, because actually I'm trying to use an old project (made with 2nd edition, I guess) with last sdk and carbide, and I know that resource definition is slightly different, so in fact everything in my project is broken.
I'm reading this document to port the project (which I suggest to everyone trying to port old applications),

http://www.forum.nokia.com/info/sw.nokia.com/id/6190aad6-3b3b-4a6a-a53a-221e61c94248/S60_Platform_Porting_from_2nd_to_3rd_Edition_v1_1_en.pdf.html

but I still have much confusion about resources. I changed something (like RESOURCE to START RESOURCE...) and now the crash is different, and this time I have also a stack trace! (I've compressed it in some way)

In case you are wondering what's in Appui.cpp:35 here is the line:
BaseConstructL(EAknEnableSkin);

Am I following the "right" way?

EDIT:
Also, these are the console last words:

69.565 Thread IMClient_0x0648A0B2::IMClient_0x0648A0B2 Panic USER 23

This is the beginning of resources, other definitions follow.
RESOURCE RSS_SIGNATURE { }

RESOURCE TBUF { buf = "IMClient"; }

RESOURCE EIK_APP_INFO
    {
    hotkeys = r_imclient_hotkeys;
    menubar = r_imclient_menubar_offline;
    cba = R_BUTTONS_OFFLINE;    
    }

Re: [Noob] - EikStart::RunApplication() makes the emulator crash

USER 23: "This panic is raised when any operation that moves or copies data to an 8 bit variant descriptor, causes the length of that descriptor to exceed its maximum length."

Are you doing something with 8 bit descriptors? Care to show the whole AppUi::ConstructL?

Edit: If you are using Carbide.C++, I suggest installing the Panic lookup plugin, which is a quick way to find out the error code and panic explanations.
