The ICustomDoc interface is implemented by MSHTML to allow a host to set MSHTML's IDocHostUIHandler interface.
ICustomDoc Methods
SetUIHandler Sets MSHTML's IDocHostUIHandler interface.
Interface Information
Implementation Custom Inherits from IUnknown Header and IDL files Mshtmhst.h; Mshtmhst.idl Minimum availability Internet Explorer 4.0 Minimum operating systems Windows 95, Windows NT 4.0
Remarks
Normally, MSHTML will call the host client site's QueryInterface method to obtain the IDocHostUIHandler interface. MSHTML implements ICustomDoc so that a host that does not implement a client site can still use MSHTML's UI customization features.
