Handles returned from CreateService must be closed using this function, rather than the standard CloseHandle

static extern IntPtr CreateService(

    Private Shared Function CreateService(ByVal hSCManager As IntPtr, ByVal serviceName As String, _

I changed the C# version from using "out uint lpdwTagId" to "string lpdwTagId". Without that change, the C# call to CreateService always returned an incorrect parameter error.

    Dim serviceHandle As IntPtr = CreateService(scHandle, serviceName, displayName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, _

    /// Required to call the CreateService function to create a service

    ''' Required to call the CreateService function to create a service

    CreateService        = 0x00002,

    CreateService = &H2
