IDispatch #3092错误 SQL语句执行错误
IDispatch #3159错误 SQL语句执行，将截断字符串或二进制数据。语句已终止。

未定义的错误 数据库连接失败

unknown error:0xE324fBB

调用m_pRecordSet->Open之前m_pRecordSet必须CreateInstance.
或者在记录标识关闭上加上这样的：
if(m_pRecordSet && m_pRecordSet->state != adStateClosed)
m_pRecordSet->Close();
m_pRecordSet=m_pConnection->Execute(bstrSql,NULL,adCmdText);

有几点建议： 1：ExitConnect() 里 m_pRecordset->Close(); 关闭前最好判断下if(m_pRecordset!=NULL) 即上面说的：if(m_pRecordSet && m_pRecordSet->state != adStateClosed)

2： 在App的InitInstance()里加个AfxOleInit();代替::CoInitialize(NULL); 和::CoUninitialize();
