How do I create a Custom Info Tab ?

Peter_Birri_(ubsuser7_-_(deleted))

I need an additional Info Tab for a WebFolder where I want display specific Info for this folder. I startet out with a WebnodeAction which prepares the data in _SubClassExecute and calls the html File in fWebScript.I managed to include the command into the "Info" Part of the function Menu and it appears also as a Tab. But the data is e displayed without the "tabby stuff" around. I assume that I have to derive from a different object than of WebNodeAction which already includes the tab functionlity, but I cannot figure out which object I should derive from. Any help is greatly appreciated.Peter
