Hi,

Are you testing app on emulator or phone?

If you are testing app on emulator..than debug code line by line and check which line it's crash.........Generally this error comes Resource missing.....

This code looks fine. In Symbian -1 means not found, have you commented or removed some code from your project so the initialization is not happening properly?

Was your coda sw in the phone was running and was connected to your PC?
Could you check that and also create the wizards to create a simple hello word type application and try to install and run it.
Please repost your findings here.
