Close Active Doc

I can not seem to close the active document.

swApp = GetObject("", "SldWorks.Application")
swModel = swApp.OpenDoc6(swFileName, 1,swOpenDocOptions_e.swOpenDocOptions_Silent, "", 0, 0)

swModel.Close()


It doesn't do anything.

If I place the command in a Try it will catch it then.

What am I doint wrong??!!SolidworksApi macros
