Version 206

No changes

Version 205

No changes

Version 204

Method and property invocation use COM direct
 interfaces when possible, instead of
 IDispatch::Invoke()
Methods and properties in inherited COM classes
 now reported by com-methods, com-get-properties,
 com-set-properties, and used properly by com-invoke,
 com-get-property, and com-set-property!
Better support for some COM VARIANT types, VT_UINT
 in particular

Version 203

The installer no longer displays dialog boxes
 when registering the MysterX .DLL files.
 Instead, successful registration prints a
 message to the current output port; a failure
 prints a message to the current error port.
Changes contributed by Joe Marshall:
 internal Marshall... procecedures renamed to
  Marshal... :-)
 mx_make_iunknown attempts to get IDispatch pointer
 if type information for a COM method is
  unavailable, the Scheme arguments are
  heuristically injected into a variant and passed
  to Invoke() without checking

Version 202

No changes.

Version 201

No changes.

Version 200

Ported to PLT Scheme 200
COM cleanup at shutdown now gets all objects
In the demo (plt/collects/mxdemo.ss), the
 mx-browser% object is instantiated using by-name
 arguments
Added block-while-browsers

Version 103-p3

Browser windows get reclaimed when browsers are
 shutdown by a custodian in DrScheme (was fixed
 in 103-p1, broken again in 103-p2)
The first HTML event is received properly after
 a custodian shutdown in DrScheme (PR 1893)

Version 103-p2

Added support for paths of property names in
 com-get-property and com-set-property!
Fixed typechecking of values supplied to
 com-set-property!
Removed right-click context menu from browser
 windows, because Language option caused errors
Added navigate/status, refresh, iconize, restore, and
 print methods to mx-browser%
Fixed and documented keycode, alt-key, ctrl-key,
 and shift-key attributes of key-{down,up,pressed}
 HTML events
Increased size of HTML event queue to 8192 from 50
Changed browser Windows event loop to use blocking

Version 103-p1:

Added optional index argument to
 find-element, find-element-by-id-or-name
 methods of mx-document%
Added methods get-html, get-text to
 mx-element% class
Added title method to mx-document% class
Methods find-element, find-element-by-id-or-name,
 and find-elements-with-tag can return the BODY
 element itself, as well as its children
When a custodian shuts down an mx-browser% object,
 its Win32 window is destroyed
Fixed marshalling of BYREF parameters to COM event
 handlers, for several types; added VT_INT and
 VT_INT | VT_BYREF
Added com-add-ref, com-ref-count procedures
Secondary Windows event loop checks for
 WM_TIMER messages; some programs were blocking
 on these when run from DrScheme

Added support for VT_INT
Added conversions com-scode->number,
 number->com-scode, com-currency->number,
 number->com-currency, com-date->date,
 date->com-date
Added predicates com-scode?, com-currency?,
 com-date?
Removed 'no-caption option for mx-browser%,
 until we can make it work

Version 102-p1:

Added synonyms cci/coclass for
 cocreate-instance-from-coclass, and cci/progid
 for cocreate-instance-from-progid
com-all-coclasses, com-all-controls return
 sorted lists
Fixed bug when methods, properties return
 NULL COM objects
Added procedure mx-version

Version 102:

cocreate-instance renamed to
 cocreate-instance-from-coclass;
 added cocreate-instance-from-progid;
 both of these procedures support
 running remote servers
for mx-document% and mx-element% classes, split
 insert-object and append-object methods into
 {insert,append}-object-from-coclass and
 {insert,append}-object-from-progid
added Scheme-syntax property getters and
 setters for HTML elements; old string versions
 are available as "-native" methods
created mx-browser% class with methods
 navigate, go-back, go-forward,
 current-url, register-navigate-handler,
 unregister-navigate-handler,
 current-document; show and event-handling
 method of mx-document% moved to the new class
constructor for mx-browser% takes same arguments
 as old constructor for mx-document%; style
 list may include 'scrollbars
com-methods no longer returns methods inherited from
 IDispatch; results are alphabetically-sorted,
 also true for com-get-properties, com-set-properties
for COM event-handling procedures, added
 check for ambiguous COM class; added
 procedures set-coclass! and
 set-coclass-from-progid! to allow
 explicit disambiguation; procedures
 coclass and progid return current value
added find-element-by-id-or-name,
 elements-with-tag to mx-document%
added methods selection and
 set-selection to mx-element%
added focus method to mx-element%;
 works with IE5 or newer only

 and word-spacing properties, since not
 implemented by IE4/5 for Windows
fixed GC-related problems with COM
 event handlers
fixed error text formatting bug when
 COM methods returned an error code
DHTML test code added,
 plt/tests/mysterx/dhtmltests.ss
improved Makefiles
Setup PLT prints warning when no binaries
 installed

Version 101:

moved Windows event loop from mx-document% class
  initialization to unit
extra Windows processing loop handles only
  WM_USER events, fixing various problems
  running MysterX under DrScheme
added AddRef() for HTML elements, fixing
  occasional crashes on GC
added tag, id information for find-element
  failures
renamed mysterx.dll to mxmain.dll, moved all
  dll's to dlls subdirectory
added clean option to Makefile

Version 100:

made changes for IE5:
  added Chris Sells' wrapper object in MysPage code

    of mx-document% and mx-element% take width, height
    arguments
added call to CoUninitialize() from exit handler

Version 100alpha4:

added support for multidimensional arrays,
  with COM SAFEARRAYs stored column-major
added com-unregister-event-handler
COM event handlers accept named arguments

  properties
garbage collection of COM objects passed to
  COM event handlers works correctly
added procedures for com-type's,
  com-object-type and com-is-a?
procedures com-methods, com-get-properties,
  com-set-properties, com-events,
  com-method-type, com-get-property-type,
