驱动在 WDK 7600.16385.0 编译通过.
易语言编译的模块提供了3个接口：
驱动操作.加载 ("服务名[文本型]", "驱动名[文本型]", "驱动路径[文本型]")
驱动操作.通信 ("驱动指令[整数型]", "输入缓冲指针[整数型]", "输入缓冲长度[整数型]", "输出缓冲指针[整数型]", "输出缓冲长度[整数型]")
驱动操作.卸载 ()
调用代码也很简单：
.版本 2
.程序集 窗口程序集1
.程序集变量 驱动, 驱动操作
.程序集变量 ProcessId, 整数型
.子程序 __启动窗口_创建完毕
.如果真 (取反 (驱动.加载 (“HideProcess”, “//./HideProcess”, 取运行目录 () ＋ “\HideProcess.sys”)))
信息框 (“加载驱动失败!”, #错误图标, “错误”)
结束 ()
.如果真结束
.子程序 __启动窗口_将被销毁
ProcessId ＝ 0
驱动.通信 (4096, lstrcpyn (ProcessId, ProcessId, 0), 4, 0, 0)
.子程序 _开关_被单击
.如果 (开关.标题 ＝ “HideOff”)
ProcessId ＝ 0
.如果真 (驱动.通信 (4096, lstrcpyn (ProcessId, ProcessId, 0), 4, 0, 0))
开关.标题 ＝ “HideOn”
.如果真结束
.否则
ProcessId ＝ GetCurrentProcessId ()
.如果 (取反 (驱动.通信 (4096, lstrcpyn (ProcessId, ProcessId, 0), 4, 0, 0)))
信息框 (“隐藏失败!”, #错误图标, “错误”)
.否则
开关.标题 ＝ “HideOff”
.如果结束
