Shell_NotifyIcon函数，向任务栏的状态栏发送一个消息
函数原型
BOOL Shell_NotifyIcon(
DWORD dwMessage,
PNOTIFYICONDATA lpdata
);
参数：
dwMessage为输入参数，传递发送的消息，表明要执行的操作。可选的值如下：
NIM_ADD
向托盘区域添加一个图标。此时第二个参数lpdata指向的NOTIFYICONDATA结构体中的hWnd和uID成员用来标示这个图标，以便以后再次使用Shell_NotifyIcon对此图标操作。
NIM_DELETE
删除托盘区域的一个图标。此时第二个参数lpdata指向的NOTIFYICONDATA结构体中的hWnd和uID成员用来标示需要被删除的这个图标。
NIM_MODIFY
修改托盘区域的一个图标。此时第二个参数lpdata指向的NOTIFYICONDATA结构体中的hWnd和uID成员用来标示需要被修改的这个图标。
NIM_SETFOCUS
Version 5.0. 设置焦点。比如当用户操作托盘图标弹出菜单，而有按下ESC键将菜单消除后，程序应该使用此消息来将焦点设置到托盘图标上。
NIM_SETVERSION
Version 5.0. 设置任务栏按照第二个参数lpdata指向的NOTIFYICONDATA结构体中的uVersion成员指定的版本号来工作。此消息可以允许用户设置是否使用基于Windows2000的version 5.0的风格。uVersion的缺省值为0，默认指明了使用原始Windows 95图标消息风格。具体这两者的区别请参考msdn中的Shell_NotifyIcon函数说明的Remarks。
lpdata为输入参数，是指向NOTIFYICONDATA结构体的指针，结构体内容用来配合第一个参数wMessage进行图标操作。
