The serviceMutex project demonstrates a way of controlling whether Performance Validator is used without having to rebuild your service.

 

Project files

 

The example project can be found in the serviceMutex sub-directory in the directory where Performance Validator was installed.

 

If the directory is not present, reinstall your software and choose custom or full installation.

 

There are two project files in the directory:

 

•serviceMutex.dsp for Microsoft® Developer Studio® 6.0  
 

•serviceMutex.vcproj for Microsoft® Visual Studio / .net
 

 

Configurations

 

There are just two configurations in each project:

 

•Debug / Release dynamically links to the svlPVStubService(_x64).lib demonstrating use with the NT Service API  
 

 

Using the service utility

 

The utility provides a dialog box interface to allow the control over the creation of a mutex object with the name specified in the service.h header file.

 

Only if the service is started with the mutex created, does the service load Performance Validator.

 

 

If you don't like using mutexes in this way, you could change the code in the service and the utility to communicate through shared memory, a registry setting or another method of your choice.
