Process Viewer  for Windows

 

Copyright 1995-2006 Igor Nys

 

Introduction

PrcView is a process viewer utility that displays detailed information about processes running under Windows. For each process it displays memory, threads and module usage. For each DLL  it shows full path and version information. PrcView comes with a command line version that allows you to write scripts to check if a process is running, kill it, etc.

What’s new in 5.0

  • Improved GUI and usability
  • Functional enhancement in many areas
  • Show CPU and memory consumption for the selected processes
  • Show system entries that are automatically executed at the start-up
  • Includes process monitoring functionality

Please note that performance and monitoring-related functionality will not run on Windows 9x/Me

What’s new in 3.0

  • DLL usage summary - displays all DLL’s currently in use, shows processes which use selected DLL
  • Displays complete task tree – parent/child relationships for all processes in the system
  • Displays Task list like the standard task manager
  • PrcView distribution now includes PV.EXE - a new utility that provides PrcView functionality from the command-line. Use pv –h for more information about available options.

What’s new in 2.0

  • Get the full list of DLL’s for each running process including FULL PATH for each loaded module - discover what DLL’s your process really uses and where they are located.
  • Double click on any module or process to get the full version information
  • Save any view as a tab-separated text file by just pressing F2
  • Process Finder Tool - just drag the finder icon and drop it to the process Window to select the desired process
  • Smooth update - you don’t need to press the refresh "button" to get the updated list of all processes, PrcView periodically updates the process list for you
  • New look and nice icons

Installation

No special installation is required on Windows 95/98. Create a new, empty folder and place the files PRCVIEW.EXE and PRCVIEW.HLP there. For Windows NT4 you may also need a PSAPI.DLL.

Main Window

The main window shows you a list of running processes including information process Id, priority, and full path to the process module. You can sort columns by clicking on the column header.

Note that although you don’t need to have administrative privilege on Windows NT to run PrcView, list of task PrcView can access depends on your set of privileges.

Show modules

Information about each loaded module including the module name, the module base address in process space, the module size and full to the loaded module path.

Show version

You can display comprehensive version information by double-clicking the appropriate line in the main or module window

Show threads

Information about all process threads including threads Id and priority. Note that if PrcView uses Performance Data Helper to enumerate threads under Windows NT, it can take a few seconds at the first time to open the list of threads while Windows is loading all necessary libraries.

Show Memory

Information about all memory blocks belonging to the selected process. Contains information about base address, protection, size and state for each memory block.

Show Heaps

Information about all heaps allocated by the selected process. You can display heap memory blocks by double clicking on the appropriate heap in the list box

Show Version

Displays version information about selected module. You can display version information by double-clicking the appropriate line in the main or module window

Kill process

Just another way to kill a selected process. Note that killing a process can cause undesired results including loss of data and system instability. The process will not be given a chance to save its state or data before it is terminated. It is advisable to try the "Notify" button in the "Kill" dialog to close a GUI-based application first (via WM_SYSCOMMAND)

Debug process

Nice way to attach a debugger to a running application. PrcView reads the "AeDebug" key and starts a registered debug application. PrcView allows you not only to select a process to debug but also to associate a particular project with it. This is especially useful while debugging an DLL that has a separate project. Associations are stored in the registry.

Set priority class

Allows you to specify a new priority class for the selected process.

The Process Finder Tool


With the Process Finder Tool you can find the process corresponding to a selected window. To find a process:

  • Arrange your windows so that PrcView and the window of the desired process are visible.
  • Press the Find Process button on the toolbar.
  • Keep left mouse button pressed while dragging the Finder Tool to the desired window.
  • Release mouse button. PrcView will select the corresponding process in the main view.

Process Tree

Shows you the process hierarchy for all running processes. You can select the desired task by clicking on the process item in the Process Tree window.

Module Usage

Information about all loaded modules in the system including the module name, the module base address in process space, the module size and full to the loaded module path. Selecting a module from the module list shows only processes witch use a selected module. Selecting "Module Usage" again returns the main window to the original process list. You can display comprehensive version information by double-clicking the appropriate line in the window.

Show Application

Shows all top-level window titles. You can select the desired task by clicking on the process item in this window. Double-click sends the selected application to the front.

Configuration option

  • Start Minimized – PrcView starts minimized. This option is useful in combination with the "Use System Tray" option if you plan to place PrcView in the "Startup" folder
  • Use System Tray – PrcView places a small icon In the System Tray, hiding itself when minimized
  • Allow Multiply Instances – If turned "on", PrcView allows to start more than one instance of the program. If turned "off" the instance of PrcView that is already running will be activated.
  • Set Refresh Times – Allows to specify refresh times for main/thread/module windows. If specified time is greater than zero, PrcView will refresh windows cyclically.

Refreshing Information

Use Menu/Toolbar in the main view or F5 in any view to refresh information in the corresponding window

Save Current View

Use Menu/Toolbar in the main view or  F2 in any view to save information in the corresponding window
