Hi Steve,

pDisp is a pointer to an instance of WebBrowser(WB) or Internetexplorer(IE).
DocumentComplete is the event IE/WB fires, when the whole document has downloaded (fires downloadComplete) and been parsed.
One of the problem's of IE/WB presents is in the area of frames, which create recursively new instances of themselves for each new frame, and fire events accordingly. Therefore it is needed to check the pDisp to be the topmost insatnce of IE/WB to be sure it is fired for the whole document.
