FastReport::frReport1.PrintPreparedReport("1",1,true,TfrPrintPages temp)

请问我上面的那个函数调用是否存在错误，因为程序结束时总是报告说应用程序产生错误；
        this->frReport1->LoadFromFile(CurPath+"xinfen.frf");
        this->frReport1->PrepareReport();
        TfrPrintPages temp=(TfrPrintPages)1;
        this->frReport1->PrintPreparedReport("1",1,true,temp);
