To avoid you to search in the previous chapters we give again our starting code where we insert the new listings given in this chapter. We give first the ooConnect() part :
// Listing 5 // C++ #include <stdio.h> #include <cppuhelper/bootstrap.hxx> #include <com/sun/star/bridge/XUnoUrlResolver.hpp> #include <com/sun/star/lang/XMultiServiceFactory.hpp> // added #include <com/sun/star/frame/XComponentLoader.hpp> using namespace com::sun::star::uno; using namespace com::sun::star::lang; using namespace com::sun::star::bridge; // added using namespace com::sun::star::frame; using namespace rtl; using namespace cppu; // a procedure for what the so called boostrap Reference< XMultiServiceFactory > ooConnect(){ // create the initial component context Reference< XComponentContext > rComponentContext = defaultBootstrap_InitialComponentContext(); // retrieve the servicemanager from the context Reference< XMultiComponentFactory > rServiceManager = rComponentContext->getServiceManager(); // instantiate a sample service with the servicemanager. Reference< XInterface > rInstance = rServiceManager->createInstanceWithContext( OUString::createFromAscii("com.sun.star.bridge.UnoUrlResolver" ),rComponentContext ); // Query for the XUnoUrlResolver interface Reference< XUnoUrlResolver > rResolver( rInstance, UNO_QUERY ); if( ! rResolver.is() ){ printf( "Error: Couldn't instantiate com.sun.star.bridge.UnoUrlResolver service\n" ); return NULL; } try { // resolve the uno-url rInstance = rResolver->resolve( OUString::createFromAscii( "uno:socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" ) ); if( ! rInstance.is() ){ printf( "StarOffice.ServiceManager is not exported from remote counterpart\n" ); return NULL; } // query for the simpler XMultiServiceFactory interface, sufficient for scripting Reference< XMultiServiceFactory > rOfficeServiceManager (rInstance, UNO_QUERY); if( ! rOfficeServiceManager.is() ){ printf( "XMultiServiceFactory interface is not exported for StarOffice.ServiceManager\n" ); return NULL; } return rOfficeServiceManager; } catch( Exception &e ){ OString o = OUStringToOString( e.Message, RTL_TEXTENCODING_ASCII_US ); printf( "Error: %s\n", o.pData->buffer ); return NULL; } return NULL; }
We second give the main() part :
//Listing 1 Again our starting main Code int main( ) { //retrieve an instance of the remote service manager Reference< XMultiServiceFactory > rOfficeServiceManager; rOfficeServiceManager = ooConnect(); if( rOfficeServiceManager.is() ){ printf( "Connected sucessfully to the office\n" ); } //get the desktop service using createInstance returns an XInterface type Reference< XInterface > Desktop = rOfficeServiceManager->createInstance( OUString::createFromAscii( "com.sun.star.frame.Desktop" )); //query for the XComponentLoader interface Reference< XComponentLoader > rComponentLoader (Desktop, UNO_QUERY); if( rComponentLoader.is() ){ printf( "XComponentloader successfully instanciated\n" ); } //get an instance of the spreadsheet Reference< XComponent > xcomponent = rComponentLoader->loadComponentFromURL( OUString::createFromAscii("private:factory/scalc"), OUString::createFromAscii("_blank"), 0, Sequence < ::com::sun::star::beans::PropertyValue >()); // add code here return 0; }
This code is called a bootstrap and uses com.sun.star.lang.XMultiServiceFactory interfaces and com.sun.star.frame.Desktop services. Remember each time you query for an interface you have to add code lines (if they don't exist) in the source code and a line in the makefile. I will generally add comments to prevent omissions. You can find more explanations here (if you are not a beginner).
