在windows中规定应用程序热键的唯一标识符取值范围在0x0000~0xBFFF之间，动态链接库的取值范围在0xC000~0XFFFF之间。 热键的辅助按键还包括Mod_Ctrl,Mod_Alt和Mod_Shift，对于windows兼容键盘，还包括windows标志键，Mod_Win。 热键设置成功后，在程序运行过程中如果有预定义的热键被按下，windows系统都会给应用程序发送一个wm_hotkey消息。 下面用一个例子演示它的使用 编译程序、运行，如果此程序不是当前桌面显示在最前边的窗体，按下ctrl+alt+a后，程序界面将出现在桌面的最上。 示例程序开发平台：D7+WINXP 转载请注明出处。 [url=http://www.wangchao.net.cn/bbs/hydetail_501490.html][img]http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif[/img][/url]unit Unit1;
