Chapter 10-Lesson 3

• An isolated task performed by Operating System is called a Process.
• An application may be using 1 or more processes.
• 32-bit processors can allocate a maximum of 4GB memory.
• Within the memory, a Virtual Memory Manager keeps setting in the form of 4KB memory pages (chunks) that it assigns to processes as and when required.
• Process class in System.Diagnostics namespace is used to handle processes through .NET
• GetProcessById( ) static method takes ID of a process as argument and throws an ArgumentException if one is not found.
• Performace for applications running on Windows can be measured using PerformanceCounter class, since it uses Registry to store values retrieved from code.
• CounterCreationData may be used to specify Name, Type and other information related to a PerformanceCounter.
• PerformanceCounterCategory class is used to manage and manipulate PerformanceCounter objects.
• The Start( ) method of the Process class may be used to invoke an outside process.
• If we use the overload of Start( ) method that takes Username and Password, then the UseShellExecute property must be set to false.
• ProcessStartInfo object may also be passed to Start( ) method to specify process name and any Command-line arguments.
• The StackTrace object represents the CLR Stack trace for a given application.
• StackTrace is composed of StackFrames which represent individual method calls.
