NT Task Manager

NT的Task Manager可以检测到某个Application 是否Hang,(Not Responding or Running).
我自己该怎样利用VC++,包括Microsoft的API 来检测一个Application是否Hang?就象Task Manager一样?

Remote Task Manager: readme ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Please read this file carefully (especially the "Installation" chapter) before installing the program to your computer. IMPORTANT! If you obtained RTM not from our web page, but from another source (CD or a software library), please visit our home page where you might find a later version. Contents ~~~~~~~~ Program information Company information Description Installation (!) Registration Copyright and license Technical support Program information ~~~~~~~~~~~~~~~~~~~ Program Archive Name: rtm.zip Program Name: Remote Task Manager Program Version: 3.8.2 Program Release Date: September 22, 2005 Target OS: Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003 Platform: Intel x86 Brief Description: The remote manager for tasks, processes, services, devices, shares and events Software type: 30-day trial Company information ~~~~~~~~~~~~~~~~~~~ Company Name: SmartLine Inc Author Name: Ashot Oganesyan Contact E-mail Address: support@protect-me.com Contact WWW URL: http://www.protect-me.com Description ~~~~~~~~~~~ Remote Task Manager (RTM) is a systems control interface that can be run from any remote Windows NT/2000/XP computer. This lets Systems Administrators control most aspects of a remote environment. The simple-to-use, tabbed interface separates applications, services, devices, processes, events, shared resources and performance monitor, making each of these very easy to manage. With RTM you can: - Monitor all running tasks, processes, services, devices, shared resources and events on remote computers - Watch features of running tasks (the handle of the main window, process ID, etc.) - Watch features of running processes (process ID, CPU time, privileges used, memory, priority, etc.) - See which process is associated with a selected task - See which process is associated with a selected service - End a selected task correctly - Terminate a selected process at any time - Change priority of a selected process - Control which CPUs the process will be allowed to execute on - Stop, start, restart, pause and continue any selected service or device - Change startup parameters of a service or a device (name, account, startup type, dependencies, etc.) - Change service's repair parameters on Windows 2000/XP - Watch dependent services or devices - Adjust service's and device's security (permissions, auditing and owner) - Clear event logs - Archive event logs - Monitor a dynamic overview of the computer's performance (CPU and memory usage) - Manage shared resources on remote computers - Monitor all open TCP and UDP ports - Shut down and reboot remote computers - Create processes on remote computers - Lock computers remotely - And much more Installation ~~~~~~~~~~~~ To install RTM you MUST have administrative privileges. Run "setup.exe". You'll need to select the target directory for the install. If you wish to install RTM without an user intervention you should run RTM Setup with the /s parameter (e.g. "c:\setup.exe /s"). This gives an install that can be used from within a batch file. There is a special configuration file for silent setup: rtm.ini. With this file, you can customize the RTM installation parameters. For example: 1. "Install" parameters: Service - RTM Service and its related files will be installed Manager - RTM Manager and its related files will be installed Documents - documentation (readme.txt, register.txt) will be installed To specify a destination directory for RTM, you can supply the parameter InstallDir If you have the registration key-file for RTM, you can specify a directory with this file in the parameter RegFileDir 2. "Misc" parameters: Run - this parameter is used to launch an application or execute a batch file after a successful install. Registration ~~~~~~~~~~~~ See "register.txt" file.
