TRAPD problem with Belle

[vineet.jain]

Just copying the classes here :

The main class:

 ============================================================================
 */

//  Include Files

#include <e32base.h>
#include <e32std.h>
#include <e32cons.h>			// Console
#include "testac.h"
//  Constants

_LIT(KTextConsoleTitle, "Console");
_LIT(KTextFailed, " failed, leave code = %d");
_LIT(KTextPressAnyKey, " [press any key]\n");

//  Global Variables

LOCAL_D CConsoleBase* console; // write all messages to this

Ctestac* c ;
CTelephony*itele;
//  Local Functions

LOCAL_C void MainL()
	{
	//
	// add your program code here, example code below
	//
	console->Write(_L("Hello, world!\n"));
	
		//TRAPD(createError1, c= new(ELeave) Ctestac(itele));
	TRAPD(createError1,c = Ctestac::NewL());
		if(createError1)
		{
		console-> Write(_L("an error create\n"));
		console->Getch();

		}
	}

LOCAL_C void DoStartL()
	{
	// Create active scheduler (to run active objects)
	CActiveScheduler* scheduler = new (ELeave) CActiveScheduler();
	CleanupStack::PushL(scheduler);
	CActiveScheduler::Install(scheduler);

	MainL();
	
	// Delete active scheduler
	CleanupStack::PopAndDestroy(scheduler);
	}

//  Global Functions

GLDEF_C TInt E32Main()
	{
	// Create cleanup stack
	__UHEAP_MARK;
	CTrapCleanup* cleanup = CTrapCleanup::New();

	// Create output console
	TRAPD(createError, console = Console::NewL(KTextConsoleTitle, TSize(
			KConsFullScreen, KConsFullScreen)));
	if (createError)
		{
		delete cleanup;
		return createError;
		}

	
	// Run application code inside TRAP harness, wait keypress when terminated
	TRAPD(mainError, DoStartL());
	if (mainError)
		console->Printf(KTextFailed, mainError);
	console->Printf(KTextPressAnyKey);
	console->Getch();

	delete console;
	delete cleanup;

	return KErrNone;
