How do I get the Service Display name in C++?

Question

I am trying to get the display name of the running service using c++. I was trying to use the GetServiceDisplayName function but it does not seem to be working, not sure why.

Answer 1

The message box will not be visible on Windows Vista and later due to a change that has services running in a separate session (Session 0 Isolation) that does not have access to a desktop so the message box would not be visible to you, the logged on user.

On Window XP and earlier, you need to tick the Allow service to interact with desktop checkbox under the Log On tab in the service's properties dialog for your service to make message box appear.

Instead, you could write the service name out to a file or run a user application that accepts the name of the service to query and have it query and display the service name (I just tried with the posted code and it works correctly, displaying the message box).
