//
// A query form object is registered under the query handlers CLSID,
// a list is stored in the registry:
//
//  HKCR\CLSID\{CLSID query handler}\Forms
//
// For each form object there are server values which can be defined:
//
//  Flags           = flags for the form object:
//                      QUERYFORM_CHANGESFORMLIST
//                      QUERYFORM_CHANGESOPTFORMLIST
//
//  CLSID           = string containing the CLSID of the InProc server to invoke
//                    to get the IQueryFormObject.
//
//  Forms           = a sub key containing the CLSIDs for the forms registered
//                    by IQueryForm::AddForms (or modified by ::AddPages), if
//                    the flags are 0, then we scan this list looking for a match
//                    for the default form specified.
