因为初学Python, 花费了几个礼拜的周末休息时间, DMB的雏形已经出来, 并提供下载使用(适合新手和偷懒的人高手跳过),有Bug和建议请及时发聩给我。
因为是初学,在编写DMB的时候,当中遇到一些问题,花费了不少时间来解决,这里总结下,也许能给后进者节约些宝贵的时间。
- 涉及GUI多线程编程的时候,使用wx.CallAfter(), 如:wx.CallAfter(self.AfterRun);
- 调用 subprocess.popen, 当子进程已经推出之后 stdin.close()调用会报错, 这时候可以用 try: process.stdin.close()??exception 来屏蔽错误;
- gzip.GzipFile 对数据流压缩很方便,可以避免临时文件的产生,解压读取方便,效率也不错;
- 获取硬件指纹 wmi 是个好东东;
- 加密解密可以用 pyDES, M2Crypto;
- 用py2exe生成.exe可执行文件的时候的icon可以用过 img2py 生成,然后在程序中设置,可以避免调用win32api,避免在 vista/win7下出错;
- wx.wizard.Wizard的 finish按钮也可以通过 wizard.FindWindowById(wx.ID_FORWARD).Disable() 来屏蔽,这个浪费了我很长时间。
这次使用wxpython,算是对桌面程序的尝试,不过趋势还是采用B/S,也方便维护和管理人员远程监控和操作管理。如果有必要,会将DMB改造成B/S构架,准备用cherrypy提供web服务,跟系统进行交互。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
