问题 Is it possible to set the Content-Type of a document in a webbrowser control? For example how can I show an XML document rendered as XML in a webbrowser control by using DocumentText? 回答1: Try add an extension to your IMoniker::GetDisplayName implementation. This will cause the URL moniker to look under HKEY_CLASSES_ROOT.??? keys for mime types. Then you can use the webbrowser's documen's IPersistMoniker interface to load the moniker. 来源： https://stackoverflow.com/questions/2570592/how-to-set
