WIN8 Service program and external app call this service

A. Service

With the help of the Win7 Service on MSDN and the "Build Service Application with VC + +", Win8 experienced all kinds of tribulations and finally ran up its own modified service program.

The original API basically did not change, I am puzzled is Win7 on the direct operation are no problem, on the Win8 can not.

Error:

OpenSCManager failed W/err 0x00000005

Originally is Win8 on the issue of permissions, perhaps my own Win7 a start to have the admin authority.

The following directly into the topic, I integrated a bit of code, a total of three files: Main.c,service.h, Service.cpp. (The project is a console program.) ）

MAIN.C is just the entry for the program, and the runtime accepts parameters.

#pragma region "includes" #include <stdio.h> #include <windows.h> #include "Service.h" #pragma endregionint wmain (int argc, wchar_t* argv[]) {if (argc > 1) && ((*argv[1] = = L '-' | | (*argv[1] = = L '/')))) {if (_wcsicmp (L "Install", Argv[1] + 1) = = 0) {Svcinstall ();} else if (_wcsicmp (L "Remove", argv[1] + 1) = = 0) {Svcuninstall ();}        else if (_wcsicmp (L "Query", Argv[1] + 1) = = 0) {svcqueryconfig ();}         else if (_wcsicmp (L "Start", Argv[1] + 1) = = 0) {Svcstart ();         } else if (_wcsicmp (L "Stop", argv[1] + 1) = = 0) {svcstopnow ();     }}else{_putws (L "Parameters:"); _putws (l "-install to install the service (Require admin permission)") _putws (L "-remove                To remove the service (Require admin permission), _putws (L "-query to query the configuration of the service");                _putws (L "-start to start the service"); _putws (L "-stop to stop the service"); Runservice ();} return 0;}

The code has been written clearly, my project name is Win8service, as long as the run Win8service.exe-install, the service will be installed.

Note: cmd must be started with admin. Win8: Win+q Key, open Search panel, enter cmd, right-click Command Prompt, select Run as Administrator.

Here's a look at the implementation of these functions:

Let's see how the results work.

Win+r, bring up run, enter services.msc to bring up service management. Here you will see Cppwin8service Demo, click on it and you will find that it is not running.

We continue to operate on the console just after the install:

D:\honeywell\workspace\win8service\debug>win8service.exe-installcppwin8service Demo installed. D:\honeywell\workspace\win8service\debug>win8service.exe-startcppwin8service Demo started.

Refresh the service and you'll see this and start.

Open Event Viewer (Run Eventvwr.msc), Cppwin8service infomation can be seen in Windows logs---application, for example:

Cppwin8serviceenter Svcinit

Second, external programs start and stop this service

The service is running, so how do we control it in an external program? In fact very simple, is to use the above Svcstart and Svcstopnow method to do it.

We create a new MFC dialog box program, add two button, one to start a stop. Copy the two functions and then include the header file.

Third, batch processing installation service Program

To put it bluntly, it is to use the SC command to install the start-up service program, with batch processing to wrap, pay attention to run batch processing also use Admin.

SC command see the SC command to create a startup service.

Service installation and startup of Bat:

@echo. Start service! @echo OFF@SC create Linctestserver binpath= "D:\XXX\Debug\NewService.exe" @sc start Linctestserver @sc Config linctestserver start= auto@sc config linctestserver displayname= "linc Service" @echo Off@echo. Start ok! @pause

Stopped bat:

@echo. Stop Service@echo off@sc stop linctestserver @echo off@echo.service stoped@pause

Uninstalled bat:

@echo. Delete Service@echo off@sc Delete linctestserver @echo off@echo.service deleted@pause
