//---------------------------------------------------------------------------
// The CMSIControl class is used to encapsulate a control which can be used
// by MSInfo to show information. This class was originally generated from
// an actual control (inserted using the component gallery). It was then
// modified to create controls with an arbitrary CLSID.
//
// Further modifications were necessary to make MSInfo truly support OLE
// controls for information categories. Specifically, we need to get the
// DISPIDs for methods and properties at runtime, rather than when the
// component was added.
