Above is the connection part of the code, the code itself has no problems, the connection can be successful, insert, query and so on, there is no problem next steps, but the code running very slow debugging found in m_pConnection - & gt; Open (strConnect, ""," ", adModeUnknown); This sentence, the program will stop 2 seconds to jump to the next, and the great spirit analysis the problem in where?
