Calc/Add-In/CompleteAddIn

We start from an example of SDK slightly modified : <OpenOffice.org1.1_SDK>/examples/DevelopersGuide/Components/CppComponent This example contains two files but I use only one file. Here is the corresponding IDL file :

#include <com/sun/star/uno/XInterface.idl>
#include <com/sun/star/lang/XInitialization.idl>
#include <com/sun/star/lang/XServiceName.idl>
#include <com/sun/star/lang/XLocalizable.idl>
#include <com/sun/star/sheet/XAddIn.idl>
module my_module
{
interface XSomething : com::sun::star::uno::XInterface
{
   string methodOne( [in] string val );
   string methodTwo( [in] string val );
};
service MyService2
{
    interface XSomething;
    interface com::sun::star::lang::XInitialization;
    interface com::sun::star::lang::XServiceName;
    interface com::sun::star::sheet::XAddIn;
};
};
