First, since "frames" most commonly applies to web applications, you're going to have to specify if this is a web app (there is an ASP.NET forum here for these questions) or a Windows Forms app. Second, if this is a Windows Forms app, how did you implement these "frames"? What controls did you use and how were they arranged? What are the initial properties, like "Visible"? Show the code you're using to hide one "frame" and how another.
