I used 1.8.o version, when I add *.qgs file, the result is 'true', but the layercount is 0. The detail code is like this:         
     QString fullPath1="D:/ProgramTest/vMap/data/newProject.qgs";
    mpMapCanvas->freeze( true );
    QgsProject::instance()->setFileName( fullPath1 );
    bool result=QgsProject::instance()->read();
    mpMapCanvas->freeze( false );
    int t=mpMapCanvas->layerCount();
 I don't know what's wrong with it.
