HandleCommandL Rise KERN-EXEC 3

[Bchgroup]

Hi.

I have some strange situation.

On device, when i press menu button "Login",
application crashes with KERN-EXEC 3.

I try, to act this way

void CsTorrentAppUi::HandleCommandL(TInt aCommand)
	{
	return;

However, it also give me a panic.

My menu is,

RESOURCE MENU_PANE r_menu
	{
	items =
		{
		// added the new Options menu command here
		MENU_ITEM
				{
				command = ECommand1;
				txt = qtn_command1;  
				},		
	   MENU_ITEM
				{
				command = ECommand2;
				txt = qtn_command2;  
      },	
	   MENU_ITEM
				{
				command = ECommand3;
				txt = qtn_command3;  
     },	
     MENU_ITEM
   				{
   				command = ECommand4;
   				txt = qtn_command4;  
        },	
   						
        MENU_ITEM
          				{
          				command = ECommand5;
          				txt = qtn_command5;  
               },			
				
               MENU_ITEM
                 				{
                 				command = ECommand6;
                 				txt = qtn_command6;  
                      },			
            
                      MENU_ITEM
                                   				{
                                   				command = ECommand7;
                                   				txt = qtn_command7;  
                                        },			
                              
     
     
     
		MENU_ITEM
				{
				command = EAknSoftkeyExit;
				txt = qtn_exit;
				}
		};
	}

"Login" is your softkey or one of the menu options?

[sumit.rathi]

Just debug your code first, then ask next question whenever you would be able to know where the problem can be.

"Login" is your softkey or one of the menu options?

Yes, it is. Binded to ECommand1, like in example.

The problem is that,on winscw emulator it work's perfect. Debug on device,doesn't work for me.
Let's i try to explain more deep.

First,
i make up an view in AppUi constructor

void CsTorrentAppUi::ConstructL()
	{
	// Initialise app UI with standard value.
	BaseConstructL(CAknAppUi::EAknEnableSkin);
	waitNoteWrapper = CAknWaitNoteWrapper::NewL();
	iTimeWaster.CreateLocal();
	// Create view object
	iAppView = CsTorrentAppView::NewL(ClientRect());
    AddToStackL(iAppView);
	}

then it goes to app view constructor

// -----------------------------------------------------------------------------
// CsTorrentAppView::ConstructL()
// Symbian 2nd phase constructor can leave.
// -----------------------------------------------------------------------------
//
void CsTorrentAppView::ConstructL(const TRect& aRect)
	{
    
	SelectedItem=0;
	MSelectedItem=1;  
	WhatToDo=0;
    login=NULL;
    pass=NULL;
	HBufC8* FilBuff(NULL);
 	RFile ReadFil;
 	
	User::LeaveIfError(iFsSession.Connect());
	iFsSession.ShareProtected();
 	TFileName aFile;		
 		
 	User::LeaveIfError(iFsSession.PrivatePath(aFile));
 	 	
 
       TParsePtrC parse((CEikonEnv::Static()->EikAppUi()->Application())->AppFullName());
 	 
	// Create a window for this application view
	CreateWindowL();
    
	
 	
 	
	// Set the windows size
	SetRect(aRect);
	
	//User::LeaveIfError(iFsSession.Connect());
	//iFsSession.ShareProtected();
	TFileName filePath;
	
	
	User::LeaveIfError(iFsSession.PrivatePath(filePath));
	
	
	filePath.Append(KMultiBitmapFilename);
	
    
    //TParsePtrC parse((CEikonEnv::Static()->EikAppUi()->Application())->AppFullName());
    filePath.Insert(0, parse.Drive());
    
    // with the help of icon-provider AknIconUtils can get get the file
    // from this application's private folder
  	iIconProvider = new (ELeave) CIconFileProvider(iFsSession, filePath);
    iBackgroundImage = AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesBgr);
    iSear=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesSear);
    iCd=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesCd);
    iDbar=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesDbar);
    iDownload=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesDownload);
    iLogo=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesLogo);
    iMobileHat=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesMobile_hat);
    iMusic=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesMusic);
    iPk=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesPk);
    iPp=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesPp);
    iSave=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesSave);
    iUser=AknIconUtils::CreateIconL(*iIconProvider, EMbmGraphicsappimagesUser);
	// Activate the window, which makes it ready to be drawn
    SetExtentToWholeScreen();
    ScrSize=CEikonEnv::Static()->ScreenDevice()->SizeInPixels();
    ActivateL();
	DrawNow();
	}

then i see all that i saw in winscw emulator
Also function TKeyResponse AppUi::HandleKeyEvent works well.
I make up setting's there and use my option's menu.

and when i use my options key, which is bind to ECommand1 i getting KERN-EXEC PANIC 3.
As i saw, panic is raised not in my code. not in HandleCommandL procedure i mean. Somewhere before.

Is it possible, to some stack error's?
What should i do for now?


By the way, i testing it on nokia e61i device, wich is symbian 9.1 version, and SDK,which i use (S60v3 FP1) to build is symbian 9.2 May be problem in this?

Some of most common causes of a Kern-exec 3 that happens on the device but not the emulator are:

- using too much stack space (do you have any large TBufs etc. on the stack?)
- accessing a pointer which is invalid (and by luck still points to something valid when executing on the emulator)

You can add logging code to pinpoint where the problem is occuring

Nothing about that(No TBufs at all).
Which pointer could be accessed when i press CommandButton?

You can also debug your application on device using TRK from carbide and can check what is happening on real device.

Yeah i really need it, but App TRK on my device... Is Running. But when i press Connect via Bluetooth... It happens nothing, and Status stay "Not connected".

May be you could help me with this issue?

Is your device connecting to your PC with bluetooth without TRK. It is the issue of connectivity and not of TRK. Just check it and let me know.

Yes, device connected very well via PC Suite.
I'm talking about, that in article i read about it, after perssing connect "Search devices" dialog should popup. And on my device, Connect affects nothing.

and,btw, trk in Carbide.c++ reports that trk-on-device is not connected.

No ideas? (

[sumit.rathi]

You have to configure the bluetooth connection in your carbide as well as in mobile device and remember TRK in your mobile should be running.
