Enumerate Windows to Detect Second Application Instance

Hi,

How does one use the EnumWindows API? I am not having any luck with this API; I would like to find the window handles of other instances of an application and act upon the findings; in Applleman's Dev Guide to Win32 API, it is mentioned that one needs to use the SpyWorks component with this API; can this API be used without any third-party "gizmo"? What is the How-To?

Thank you!
