change softkey shortcuts on an "installing-SIS-file application"

[mike_p]

Hi

I want to change the shortcut softkeys as described here: http://wiki.forum.nokia.com/index.ph...ne_Wrapper_API

I've followed the steps and it works for stand-alone applications, but does not for an "installing-SIS-file application". Is there a way to do it?

[ltomuta]

I don't understand what you mean by an "installing-SIS-file application"? What's special about it, what works and what not? And if it does not work, how exaclty does it fail?

[wizard_hu_]

Perhaps mike_p wants a .sis file to be installed (instead of an application to be executed), but that is only a guess. In that case it could be still viable to create an executable for launching the installer (even in the silent way).

[mike_p]

wizard_hu_, you guessed correctly - I want a .sis file to be installed instead of an application to be executed.

I have created a console application and run. it did not return any error code, it just crashed.

[mike_p]

The following imperative makes the program crash:

iShortcut = CScShortcutEngineWrapper::NewL(iSession,*this);

(code originaly taked from http://wiki.forum.nokia.com/index.ph...ne_Wrapper_API)

[wizard_hu_]

Check http://wiki.forum.nokia.com/index.ph...ded_panic_code then.

I had a case where my program crashed without "Program closed:/n%S"... does this denote a "panic" situation as well?

[mike_p]

My application doesn't prompt a "Program closed:/n%S" message or gives an "App. closed" message...

[ltomuta]

Just to make sure, have you installed the errrd.sis file?

[Paul.Todd]

The issue we had with this API was that if you are running it from the installer you CANNOT guarantee that your API will be registered with the application manager by the time the shortcut creator app is run. You need to delay and retry until your application is found (ie keep calling AsynchronouslyPrepareShortcutListL)

Anyway there insufficient information to determine what you are doing from the HandleShortcutEvent

[mike_p]

ltomuta, what is the errrd.sis file good for and how do I use it?

Paul.Todd, my application crashes before I get a change to call AsynchronouslyPrepareShortcutListL, it crashes on the instantiation of the CScShortcutEngineWrapper. Anyway, can you please post a reference to applying this technique? As a .net developer, I would use try..catch inside a loop with a delay, but I'm a newbie with Simbian/Open c.... And, is there any information in HandleShortcutEvent that can help me overcome the crashing problem?

Thanks, ltomuta and Paul.Todd.

[Paul.Todd]

As I said in the original post, you must post your code.
Also follow Wizard's advice and enable error logging so you know what the crash is.

The fact the example code works and your does not does rather indicate its a problem in your code.

Which device are you trying this on?

[mike_p]

* My code is listed below. The application is a console application.

* The device is E51.

* How do I enable error logging? Wizard is referring to a "panic" case - is this my case?

If your application generates a panic it will be closed and an error note is shown by the OS

My application doesn't generate such a message, it just crashes. And, I don't see any mention of "errrd.sis" file there.

* I'm interested to try this:

You need to delay and retry until your application is found

Can you please provide some directions/references of how to perform this?

* Thanks

To prevent a lot of pain, derive your class from CBase *** and make sure CBase is first in the list (ie before any M classes) ***

Revise your handling of non gui applications, you need a trap harness and active scheduler

Panic's are the same errors and you have to enable them

[mike_p]

Thakns.

* Sorry, the last section of the code I posted was partial - it was generated by a the Carbide. I think that your note "Revise your handling of non gui applications, you need a trap harness and active scheduler" is already taken care of, is this correct? (More code is listed below)

* How do I enable Panic errors?
