ControlService()API创建服务的新实例 [英] ControlService() API creating a new instance of the service

问题描述

我正在使用以下代码停止该服务. ControlService() API正在调用该服务的OnStartService()处理程序.因此，创建服务的新实例.

I am using the following code to stop the service. ControlService() API is giving call to OnStartService() handler of the service. Hence creating a new instance of the service.

// Open a connection to the SCM
    scm = OpenSCManager(0, 0, SC_MANAGER_CONNECT);
    csMsg.LoadString(IDS_INOPENSCMGR);	
    // Get the service's handle
    service = OpenService(scm, SERVICE_NAME,
        SERVICE_ALL_ACCESS | DELETE);
                
    success = ControlService(service, SERVICE_CONTROL_STOP,&status);

有什么方法可以防止ControlService() API不能像这样.
谢谢，
Sunil

Is there some way to prevent ControlService() API not to behave like this.
Thanks,

推荐答案

您是否正在使用某些包装器类?如果是这样，您需要提及.

如果您没有使用一个，而是使用直接API，则在ServiceCtrlHandler 中，您需要适当地处理它.我的一篇文章中的示例代码:

Are you using some wrapper class? If so you need to mention that.

If you are not using one, and you are using straight API, then in your ServiceCtrlHandler you need to handle that appropriately. Example code from one of my articles:

switch(nControlCode)
{	
case SERVICE_CONTROL_SHUTDOWN:
case SERVICE_CONTROL_STOP:
	nServiceCurrentStatus=SERVICE_STOP_PENDING;				
	success=UpdateServiceStatus(SERVICE_STOP_PENDING,NO_ERROR,0,1,3000);
	KillService();		
	return;
default:
	break;
}

这是文章:

Here''s the article:

Once again, if you are using some wrapper class then you need to look at how you need to specially handle service termination (via the API exposed by the wrapper).
