为什么我使用 char* szDesc;
            int mlen;
            szDesc=new char[256];
            sprintf(szDesc,"DSN=%s: DESCRIPTION=TOC support source: DBQ=%s: FIL=MicrosoftAccess: \
                DEFAULTDIR=D:\\Database:: ","TEST","Database\\Test.mdb");
            mlen = strlen(szDesc);
            for (int i=0; i<mlen; i++)
            {
                if (szDesc[i] == ':')
                    szDesc[i] = '\0';
            }
            
            if (FALSE == SQLConfigDataSource(NULL,ODBC_ADD_DSN,\
                    "Microsoft Access Driver (*.mdb)\0",(LPCSTR)szDesc))
配置的数据源路径不是 D:\\Database\\Test.mdb，而是C:\Documents and Settings\zyd\桌面\DbTest1\Database\\Test.mdb呢 ？

if (FALSE == SQLConfigDataSource(NULL,ODBC_ADD_DSN, "Microsoft Access Driver (*.mdb)\0",\
                 (LPCSTR)"DSN=TEST\0DBQ=D:\\Database\\Test.mdb\0"))
这样就OK！！
