实例演示:例如要打开控制面板,可以在运行里输入:rundll32 shell32,Control_RunDLL另外一个用途就是可以在程序中调用以下程序winexec(Pchar('StrCommand'),sw_Show); 其中"StrCommand"代表以下命令之一(使用Windows中的运行不要加引号): "rundll32 shell32,Control_RunDLL" - 运行控制面板 "rundll32 shell32,OpenAs_RunDLL" - 打开"打开方式"窗口 "rundll32 shell32,ShellAboutA Info-Box" - 打开"关于"窗口 "rundll32 shell32,Control_RunDLL desk.cpl" - 打开"显示属性"窗口 "rundll32 user,cascadechildwindows" - 层叠全部窗口 "rundll32 user,tilechildwindows" - 最小化所有的子窗口 "rundll32 user,repaintscreen" - 刷新桌面 "rundll32 shell,shellexecute Explorer" - 重新运行Windows Explorer "rundll32 keyboard,disable" - 锁写键盘 "rundll32 mouse,disable" - 让鼠标失效 "rundll32 user,swapmousebutton" - 交换鼠标按钮 "rundll32 user,setcursorpos" - 设置鼠标位置为(0,0) "rundll32 user,wnetconnectdialog" - 打开"映射网络驱动器"窗口 "rundll32 user,wnetdisconnectdialog" - 打开"断开网络驱动器"窗口 "rundll32 user,disableoemlayer" - 显示BSOD窗口, (BSOD) = Blue Screen Of Death, 即蓝屏 "rundll32 diskcopy,DiskCopyRunDll" - 打开磁盘复制窗口 "rundll32 rnaui.dll,RnaWizard" - 运行"Internet连接向导", 如果加上参数"/1"则为silent模式 "rundll32 shell32,SHFormatDrive" - 打开"格式化磁盘(A)"窗口 "rundll32 shell32,SHExitWindowsEx -1" - 冷启动Windows Explorer "rundll32 shell32,SHExitWindowsEx 1" - 关机 "rundll32 shell32,SHExitWindowsEx 0" - 退当前用户 "rundll32 shell32,SHExitWindowsEx 2" Windows9x 快速重启 "rundll32 krnl386.exe,exitkernel" - 强行退出Windows 9x(无确认) "rundll rnaui.dll,RnaDial "MyConnect" - 运行"网络连接"对话框 "rundll32 msprint2.dll,RUNDLL_PrintTestPage" - 选择打印机和打印测试页 "rundll32 user,setcaretblinktime" - 设置光标闪烁速度 "rundll32 user, setdoubleclicktime" - 测试鼠标双击速度 "rundll32 sysdm.cpl,InstallDevice_Rundll" - 搜索非PnP设备 控制面板中的各项功能 winexec('rundll32.exe shell32.dll, Control_RunDLL', 9);
