Hi,

When trying to self delete our application by using following code,the application is not removed if we do Device.requestPowerOff(false) but the application is removed if we do CodeModuleManager.promptForResetIfRequired(). So PowerOff != Reset?

So my question is, is there a way to do a programtic reset that will remove our application? Or am I doing something wrong to do a self delete in our application?

This is happening on 

8800

v4.2.1.7.4

Platform 2.3.0.5.4

Thanks for your time.

ApplicationDescriptor ad = ApplicationDescriptor.currentApplicationDescriptor();
int moduleHandle = ad.getModuleHandle();
int rc = CodeModuleManager.deleteModuleEx(moduleHandle, true);

switch (rc) 
        {            
            case CodeModuleManager.CMM_OK_MODULE_MARKED_FOR_DELETION:
                CodeModuleManager.promptForResetIfRequired();
                //Device.requestPowerOff( false );
                break;
            case CodeModuleManager.CMM_OK:
                //do something
                break;            
            case CodeModuleManager.CMM_MODULE_IN_USE:
            case CodeModuleManager.CMM_MODULE_IN_USE_BY_PERSISTENT_STORE:
                //do something
                break;
            case CodeModuleManager.CMM_HANDLE_INVALID:                
                //do something
                break;
            case CodeModuleManager.CMM_MODULE_REQUIRED:                
                //do something
                break;
            default:
                //do something
                break;
        }

You are correct, power off is not the same as reset.  Power off suspends running applications and puts the BlackBerry in a "sleep" mode.  When it is powered on applications resume from where they left off.  This is the same as powering on/off a BlackBerry using the power button or red end key (varies based on model).  The BlackBerry can power on almost instantly from this state.

A reset more closely resembles removing and reinserting the battery.  This stops all applications and the JVM.  When the BlackBerry restarts, the JVM restarts along with any auto-start applications.  This process takes a few minutes.

If promptForResetIfRequired yields true, then it means the BlackBerry is unable cod files until the BlackBerry is restarted.  The link below lists reasons why this may occur.
