摘要：
上次，我写了一篇关于如何在VB中制作QQ自动登录设备的日志，介绍了如何使用模拟键盘输入的方式实现QQ自动登录。后来，我找到了另一种方法，在互联网上使用QQ命令行实现自动登录，这显然更好。命令行的格式为“QQ应用程序路径/STARTQQUIN:QQ号PWDHASH:Base64/STAT:登录模式”。有两种登录模式：40和41。40表示不可见登录，41表示正常登录。了解了命令行的格式后，我们可以直接调用WinAPI Winexec来实现QQ的自动登录。
上一次写过一篇VB制作QQ自动登录器的日志，介绍用得是模拟键盘输入的方式实现QQ的自动登录。这种方式有一种缺陷，就是必须保持输入焦点的正确，否则很容易就打乱了程序的执行过程，造成无法登录。特别是一开机就运行该程序，然后该程序去调用QQ的时候，Win API Winexec执行特慢，导致程序跟不上QQ，输入焦点也错了。后来在网上又发现了一种用QQ命令行的方式来实现自动登录的，这种方式明显更好用。该命令行的格式为“QQ应用程序路径 /START QQUIN:QQ号码 PWDHASH:Base64(MD5(QQ密码)) /STAT:登录模式”。
QQ应用程序的路径我们可以在注册表下面找到，而需要注意的是QQ密码必须是经过MD5加密过的，再用Base64编码一次。登录模式则有40和41两种，40表示隐身登录，41表示正常登录。了解了命令行的格式后我们就直接调用Win API Winexec就可以实现QQ的自动登录了。下面给出实现代码：

该程序用ACCESS保存QQ的密码信息，可以实现批量登录。当你有多个QQ号码需要登录的时候就不用一个个去按QQ输密码了。程序还有一个需要改进的地方，就是保存密码的时候保存的是明文，虽然数据库加了密码，但现在ACCESS数据库好像不是很安全，网上经常看到有破解ACCESS数据库密码之类的文章。所以建议大家在保存密码的时候最好再加个自己的加密的方法。(直接保存密码的MD5也是不安全的喔，别人知道了MD5一样是可以登录你QQ的) Public g_strNum As String '保存主窗口传递过来的QQ号码变量
