Which of the following is the first program which will run after starting the system immediately

I have a Windows Service which I install using the InstallUtil.exe. Even though I have set the Startup Method to Automatic, the service does not start when installed, I have to manually open the services and click start. Is there a way to start it either via the command line, or through the code of the Service? In your Installer class, add a handler for the AfterInstall event. You can then call the ServiceController in the event handler to start the service. using System.ServiceProcess; public ServiceInstaller() Now when you run InstallUtil on your installer, it will install and then start up the service automatically. After refactoring a little bit, this is an example of a complete windows service installer with automatic start: using System.ComponentModel; using System.Configuration.Install; using System.ServiceProcess; namespace Example.of.name.space This code gave me the following error/s: An exception occurred during the Install phase. System.InvalidOperationException: An exception occurred in the OnAfterInstall event handler of System.ServiceProcess.ServiceInstaller. The inner exception System.InvalidOperationException was thrown with the following error message: Cannot start service serviceName on computer '.'.. The inner exception System.ComponentModel.Win32Exception was thrown with the following error message: The executable program that this service is configured to run in does not implement the service. The errors seized once I commented out the line "Initiali...

When we turn on our computer installed operating system will start working. It ensures the co-ordination of other stored programs with system's hardware components.To enable operating system a Process is done which is called "Booting". It is performed by a software stored in our system BIOS(basic input-output system). BIOS does the following functions: a)perform a Power-on self-test : this is done to make sure that other parts of computer are working properly or not. b)It then checks if Rebooting is necessary or not,if not it does a Read/write test for RAM. While performing these operations you can see a black window showing some text.it is nothing but the information about CPU,memory and hard disks which given by BIOS software.After booting up, all control PC is given to Operating system.And now you are able to work on your personal computer. (basic input/output system) It is a program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk , video adapter , keyboard , mouse , and printer .

//same program different code #include #include #include int main() I tried this , I hope its correct . But I am not satisfied with the output . The output is : Hello I am the parent process My actual pid is 4287 ashu@ashu-VirtualWorld:~/Desktop/4thSemester/testprep$ Hello I am the child process My pid is 4288 Please help me I cant understand its output , I want the child process to occur first and then parent process . Also , when the execution ends the control is transferred to the program , so to return to terminal I have to use ctrl+c , I want that after the execution of the program ends the control transfers to the terminal . Yeah, the answer of unwind says it pretty much precisely...they're supposed to run in parallel. Which means they both get their own time slices of processor time and take turns in 'executing' (basics of multitasking). Now, your child process will pretty much always be a little behind your parent process, because the parent process is still 'it' until the end of its current time slice, while the child process has to wait his turn. #include #include #include #include int main() { int status; int pid; pid=fork(); if(pid 0 means parent so the parent and child are running in the same time access the same resource so the problem of the race condition occur. The which one is first access the resource its executed first and another one is executed at later time. The wait function avoid the race condition and when the child execution complete until the p...

Starts one or more processes on the local computer. In this article Syntax Start-Process [-FilePath] [[-ArgumentList] ] [-Credential ] [-WorkingDirectory ] [-LoadUserProfile] [-NoNewWindow] [-PassThru] [-RedirectStandardError ] [-RedirectStandardInput ] [-RedirectStandardOutput ] [-WindowStyle ] [-Wait] [-UseNewEnvironment] [-WhatIf] [-Confirm] [] Start-Process [-FilePath] [[-ArgumentList] ] [-WorkingDirectory ] [-PassThru] [-Verb ] [-WindowStyle ] [-Wait] [-WhatIf] [-Confirm] [] Description The Start-Process cmdlet starts one or more processes on the local computer. By default, Start-Process creates a new process that inherits all the environment variables that are defined in the current process. To specify the program that runs in the process, enter an executable file or script file, or a file that can be opened using a program on the computer. If you specify a non-executable file, Start-Process starts the program that's associated with the file, similar to the Invoke-Item cmdlet. You can use the parameters of Start-Process to specify options, such as loading a user profile, starting the process in a new window, or using alternate credentials. Examples Example 1: Start a process that uses default values This example starts a process that uses the Sort.exe file in the current folder. The command uses all the default values, including the default window style, working folder, and credentials. Start-Process -FilePath "sort.exe" Example 2: Print a text file This example st...

Write the PLC Programming Motors logic for the following problem. • There are three motors (M1, M2 & M3), having a separate start and stop push button. • M1 must be running before starting of M2 and M3 motor. • M2 and M3 can start and stop without affecting M1 operation. • Only two motors can run at the time. Starting of the third motor will shut down all the outputs immediately irrespective of its input. PLC Programming Motors Program Description: Rung 0000: Start/Stop PB latched with memory B3:0/0 for Motor 1.B3:0/3 is connected in series with Rung 0001: Start/Stop PB latched with memory B3:0/1 for Motor 2 .B3:0/0 is connected in series to turn on M2 only after M1. Rung 0002: Start/Stop PB latched with memory B3:0/2 for Motor 3 .B3:0/0 is connected in series to turn on M3 only after M1. Rung 0003: Turning on M1 when B3:0/0 turns ON Rung 0004: Turning on M2 when B3:0/1 turns ON Rung 0005: Turning on M3 when B3:0/2 turns ON Rung 0006: M2 and M3 outputs are connected in series to enable B3:0/3 Program Output: When M1 turns ON,

\( \newcommand\) • The following is a first MIPS assembly program. It prints out the string " Hello World". To run the program, first start the MARS program. Choose the File->New menu option, which will open an edit window, and enter the program. How to run the program will be covered in the following the program. Program 2-1: Hello World program # Program File: Program2-1.asm # Author: Charles Kann # Purpose: First program, Hello World .text # Define the program instructions. main: # Label to define the main program. li $v0,4 # Load 4 into $v0 to indicate a print string. la $a0, greeting # Load the address of the greeting into $a0. syscall # Print greeting. The print is indicated by # $v0 having a value of 4, and the string to # print is stored at the address in $a0. li $v0, 10 # Load a 10 (halt) into $v0. syscall # The program ends. .data # Define the program data. greeting: .asciiz "Hello World" #The string to print. Once the program has been entered into the edit window, it needs to be assembled. The option to assemble the program is shown circled in red below. Figure 2-4: Assembling a program If you entered the program correctly you should get the edit screen below. If you made any errors, the errors will be displayed in a box at the bottom of the screen. To run the program, click the green arrow button circled in the figure below. You should get the string " Hello World" printed on the Run I/O box. You have successfully run your first MIPS program.
