4. What is process ? In computing, a process is an instance of a computer program that is being executed. It contains the program code and its current activity. A process may be made up of multiple threads of execution that execute instructions concurrently. A computer program is a passive collection of instructions; a process is the actual execution of those instructions. Several processes may be associated with the same program; for example, opening up several instances of the same program often means more than one process is being executed.

5. Overview Process Viewer provides facilities like view running process with their memory consumption, process start-time, kill selected process, view the fully qualified path from where .exe file is resides and more important it manage user wise history for further usage. Process Viewer is multi threaded application that provides various useful functions for processes and application running in user system. “ Process Viewer provides facilities like view running process with their memory consumption, process start-time, kill selected process, view the fully qualified path from where .exe file is resides and more important it manage user wise history for further usage.

Learning Objectives C++ OOPS Funda • Inheritance • Exception handling • Virtual function • Friend function • Operator overloading (<< for Display O/P) • Namespace • Run Time Type Identification (RTTI) • Method Overloading • Template (generic Programming) • Enum • And other general OOPS funda Advanced Funda • Linked List (Data structure) • Multi-Threading • System Programming • Database application • Partially ORM implementation C++ OOPS Funda • Inheritance • Exception handling • Virtual function • Friend function • Operator overloading (<< for Display O/P) • Namespace • Run Time Type Identification (RTTI) • Method Overloading • Template (generic Programming) • Enum • And other general OOPS funda Advanced Funda • Linked List (Data structure) • Multi-Threading • System Programming • Database application • Partially ORM implementation
7. User Interaction
8. Application Functions View Processes Shows list of running processes including information like process Id, process name and process memory usage and starting time. List will be refresh when new process arrives or terminate. Kill Process User can terminate unwanted process. Process Path User can view full path of executable component though can be also useful in detection and removing spyware , virus or any unwanted process/Application. In process viewer show path where component is loaded. View Processes Shows list of running processes including information like process Id, process name and process memory usage and starting time.

In process viewer show path where component is loaded.
9. Application Functions History Process viewer manage user-wise process log as a history. Application doesn’t require user authentication it work on system authentication So, There is no need for remember username and password. User can view only his/her history for particular time interval. It displays process name, process start-End Date&Time. So user can let know which process had start and when it was terminated. Run in Background This application can also run in background. User can also back from background mode. History Process viewer manage user-wise process log as a history.

10. Understanding Application Architecture
11. Technology Used MySQL, the most popular Open source, relational database management system, is developed, distributed, and supported by Oracle Corporation. Pthread The POSIX thread libraries are a standards based thread API for C/C++. It is most effective where the process flow can be scheduled to run on another processor thus gaining speed through parallel or distributed processing. Pthread
