如何以ATL服务项目的形式制作蜂鸣器程序？

Question

How to make a program which beeps every 1 second in ATL.

I've tried to made a new ATL project (Service EXE) and in this method :

ProjectNameModule::ServiceMain(...){
    Beep(1000,50);
    //...
}

I've included this line

Beep(1000,50);

But running this, wouldn't give the expected result.

Any brilliant idea, please?

ATL Service application, created from template, does not run as service until explicitly switched.

You need to run from command line: MyProject.exe /service and this will create the actual service. Then you start the service from management console etc., or it is started when external application requested COM object hosted by this service/application.

Service is unregistered with /unregserver or /regserver , in the latter case the application hosts COM classes from regular application, as opposed to service.
