You didn't mention that you included <com/sun/star/frame/XStorable.hpp>
in your file. Perhaps you forgot to do that?

down the complete code for creating the desktop object and without any
handling of exceptions:
#include <rtl/ustring.hxx>
#include <com/sun/star/uno/Reference.hxx>
#include <com/sun/star/uno/Sequence.hxx>
#include <com/sun/star/lang/XComponent.hpp>
#include <com/sun/star/frame/XComponentLoader.hpp>
#include <com/sun/star/frame/XStorable.hpp>
#include <com/sun/star/beans/PropertyValue.hpp>
using namespace com::sun::star;
// add code to create Desktoo object
uno::Reference < frame::XDesktop > xDesktop;
// properties for loading might be added here
uno::Sequence < beans::PropertyValue > aProps;
// example file name
::rtl::OUString aFileName =
:rtl::OUString::createFromAscii("file:///home/user/myfile.odt");
// create new window
::rtl::OUString aTargetFrame = rtl::OUString::createFromAscii("_blank");
uno::Reference < frame::XStorable >
xStor( xDesktop->loadComponentFromURL( aFileName, aTargetFrame, 0,
aProps ), uno::UNO_QUERY );
// more properties for storing might be added here
uno::Sequence < beans::PropertyValue > aStoreProps(1);
aStoreProps[0].Name = ::rtl::OUString::createFromAscii("Overwrite");
aStoreProps[0].Value <<= sal_True;
// example file name for storing
::rtl::OUString aFileName =
:rtl::OUString::createFromAscii("file:///home/user/mynewfile.odt");
xStorable->storeToURL( aNewFile, aStoreProps );
Some of the includes may be superfluous as they might be nested into
others anyway. Please watch that runtime library headers are included as
"hxx", while API headers have the extension "hpp".
I recommend to send questions like this to the "dev" or "d...@api" list
in future.
