专家，你好。我是VC初学者，目前开发一个小型采购服务软件，后台是SQL2k。有这么一段代码，您能给出指点吗？<br/>ExecProc(const       CString&       strProcName,               \\要执行的存储过程名字   <br/>                                    long*       returnIntfromProc,                           \\存储过程返回值在VC6中对应的变量   <br/>                                    const       CString&       strInParam,                   \\传递给存储过程的输入参数   <br/>                                    CString&       strOutParam)                                       \\存储过程的output参数对应的C  变量   <br/>{   <br/>//       定义智能指针，并初始化   <br/>_ConnectionPtr       Conn;   <br/>Conn.CreateInstance(__uuidof(Connection))   <br/>_CommandPtr       cmd;   <br/>_RecordsetPtr       rsp;   <br/>_ParameterPtr       returnParam,INParam,OutParam;   <br/>try{   <br/>cmd.CreateInstance(__uuidof(Command));   <br/>rsp.CreateInstance(__uuidof(Recordset));   <br/>cmd->   ActiveConnection       =       Conn;   <br/>cmd->   CommandText       =       _bstr_t(strProcName);       <br/>returnParam=cmd->   CreateParameter(_bstr_t("returnParam"),adInteger,adParamReturnValue,sizeof(int));   <br/>    cmd->   Parameters->   Append(returnParam);   <br/>INParam=cmd->   CreateParameter(_bstr_tINParam"),adBSTR,adParamInput,300,(_variant_t)strInParam);   <br/>cmd->   Parameters->   Append(INParam);   <br/>OutParam=cmd->   CreateParameter(_bstr_t("OutParam"),adBSTR,adParamInput,300);   <br/>cmd->   Parameters->   Append(OutParam);   <br/>cmd->   Execute(NULL,       NULL,       adCmdStoredProc);   <br/>                                //       往后的工作是把存储过程的返回值returnParam中的值取到对应的C  变量returnIntfromProc中，   <br/>                                //           把存储过程的返回参数OutParam中的值取到对应的C  变量strOutParam   <br/><br/>//怎么做？？？！！！
