调用的DLL命令:

.DLL命令 API_CoCreateInstance, 整数型, "ole32.dll", "CoCreateInstance", , 　
    .参数 rclsid, 字节集
    .参数 pUnkOuter, 整数型
    .参数 dwClsContext, 整数型
    .参数 riid, 字节集
    .参数 ppv, 整数型, 传址

.DLL命令 API_PostMessage, 整数型, "user32", "PostMessageA", , 将一条消息投递到指定窗口的消息队列。投递的消息会在Windows事件处理过程中得到处理。在那个时候，会随同投递的消息调用指定窗口的窗口函数。特别适合那些不需要立即处理的窗口消息的发送　如消息投递成功，则返回TRUE（非零）。会设置GetLastError
    .参数 hwnd, 整数型, , 接收消息的那个窗口的句柄。如设为HWND_BROADCAST，表示投递给系统中的所有顶级窗口。如设为零，表示投递一条线程消息（参考PostThreadMessage）
    .参数 wMsg, 整数型, , 消息标识符
    .参数 wParam, 整数型, , 具体由消息决定
    .参数 lParam, 整数型, , 具体由消息决定;

.DLL命令 API_SendMessage, 整数型, "user32", "SendMessageA", , 调用一个窗口的窗口函数，将一条消息发给那个窗口。除非消息处理完毕，否则该函数不会返回。SendMessageBynum， ;    SendMessageByString是该函数的“类型security”声明形式　由具体的消息决定
    .参数 窗口句柄, 整数型, , 要接收消息的那个窗口的句柄
    .参数 信息值, 整数型, , 消息的标识符
    .参数 参数一, 整数型, , 具体取决于消息
    .参数 参数二, 整数型, , 具体取决于消息;
