 一、安装远程服务器管理工具:

Tomcat Native是用于Tomcat的一个可选组件,能够允许Tomcat使用一定的本地资源、性能、兼容性。

ag真人,CHECKER2程序包含一个键盘接口,内容与CHECKER1完全相同。利用←、→、↑、↓四个方向键可以在25个矩形之间移动鼠标指针。Home键把鼠标指针移动到左上角的矩形;End键使鼠标指针落到右下角的矩形。空格键和回车键都可以切换X形标记。

具体来说,Tomcat Native给了Tomcat访问 Apache Portable Runtime(APR)的网络连接实施和随机数发生器。

 二、关闭远程服务器管理工具:

  • 非阻塞I/O请求(请求之间保持)
  • 使用OpenSSL TLS / SSL功能(如果链接APR库支持)
  • FIPS 140-2支持TLS / SSL(如果与OpenSSL库支持)

CHECKER2.C

  1 在桌面上右击“开始”,进入“程序和功能”

具体参考:

在CHECKER2程序中,处理WM_KEYDOWN时利用GetCursorPos判断指针的位置,并利用ScreenToClient将屏幕坐标转换成客户区坐标,然后将坐标值除以矩形块的宽和高,得到x和y。这些x和y的值表示了矩形在5*5数组中的位置。当按下某个键时,鼠标指针可能在客户区也可能不在客户区内,因此x和y必须包含在min和max的宏处理中,保证它们的范围处于0和4之间。

  2 单击程序,然后在程序和功能中单击“启用或关闭 Windows 功能”。

话不多说,直接上教程

对于方向键,CHECKER2程序相应的增加或减少x和y的值。若按下回车键或空格键,CHECKER2程序调用SendMessage给自己发送一个WM_LBUTTONDOWN消息。最后,WM_KEYDOWN处理逻辑计算得到指向矩形中心的客户区坐标,并调用ClientToScreen将其转换成屏幕坐标,最后调用SetCursorPos设置指针的位置。
