搞了个C的版本，后面再搞MFC界面

 #include <stdio.h>
#include <windows.h>
#include <mysql.h> 

#define TIP_ERROR_CONNECT   "Connection error #%d!\n"
#define TIP_CONNECT_OK      "Mysql %s has connected!\n"
#define TIP_TEST            "MySQL database testing...\n"

#define SQL_TEST    "SELECT ID,post_title FROM wp_posts;\n"

#define USER        "root"
#define PASSWORD    "pass"
#define HOST        "localhost"
#define PORT        3306
#define DATABASE    "hyc_hr"

void query(MYSQL db, char *sql){

    printf(TIP_TEST);
    printf("SQL: %s", sql);

    MYSQL_RES *rs;
    MYSQL_ROW row;
    unsigned long *len;
    unsigned long fc, rc;

    if(0!=mysql_query(&db,sql)){
        printf("ERR %s\n", mysql_error(&db));
        return;
    }
    //rs = mysql_use_result(&db);
    rs = mysql_store_result(&db);
    if(NULL==rs){
        printf("ERR mysql_use_result #%d %s", mysql_errno(&db),mysql_error(&db));
        len = int(0);
    }
    fc = mysql_field_count(&db);
    rc = mysql_num_rows(rs);
    len = mysql_fetch_lengths(rs);
    if(NULL==len){
        printf("ERR mysql_fetch_lengths #%d %s", mysql_errno(&db),mysql_error(&db));
        len = new unsigned long(0);
    }
    printf("%d data rows, %d field count, %d fetch lengths.", rc, fc, *len);

    while ((row = mysql_fetch_row(rs)) != NULL)
       printf("%s\t%s\n", row[0],row[1]);
    mysql_free_result(rs); /* NEVER forget this free */

}

int main()
{

    MYSQL db;
    mysql_init(&db);
    if(mysql_real_connect(&db,HOST,USER,PASSWORD,DATABASE,PORT,NULL,0)){
        printf(TIP_CONNECT_OK, mysql_get_server_info(&db));
        query(db,SQL_TEST);
    }else{
        printf(TIP_ERROR_CONNECT, mysql_errno(&db));
        fprintf(stderr, "ERR: %s\n", mysql_error(&db));
    }

    mysql_close(&db);

    return 0;
}
