Delete IBase using custom report program

Hi all,

I am trying to delete IBase in CRM using code. I tried FM IB_COM_NEW  to get handle and passed the handle to FM IB_IBASE_DELETE_IBASE but I am getting an exception IB_HANDLE_NOT_DEFINED.

i saw post regarding archiving but I want to delete the ibase. Please suggest what value to be passed  to handle or some other way to delete the ibase.

Thank you.
