Trivial it ain't! More on Quicktime and IE6
by Rzepa, Henry 26 Jun '02

26 Jun '02

This is the official solution for allow plugins (in this case Quicktime) to again be played on MS IE 5.5 SP2 and IE6 XP. One presumes a similar solution will be required for Chime and other Chemical plugins. The example below suggests that an ActiveX control is downloaded from the Internet. I presume a stand alone solution suitable for eg CDROMs will also materialise. Note how the onus is on the content developer to CHANGE their HTML page to make it work. I wonder how many will. (Thanks to Jonathan Brecher for the information!) >Date: Tue, 21 Aug 2001 15:11:58 -0700 (PDT) >Subject: Important News For Quicktime Developers >From: Apple Developer Connection <noreply(a)wwdr.apple.com> >Reply-To: Apple Developer Connection <noreply(a)wwdr.apple.com> >To: undisclosed-recipients:; > > >Windows Internet Explorer 5.5 SP2 and 6.0 with QuickTime >IMPORTANT INFORMATION FOR WEB DEVELOPERS & WEBMASTERS > >Microsoft Internet Explorer for Windows, versions 5.5 SP2 and 6.0 >(soon to be released) no longer support Netscape-style plug-ins, >such as the plug-in installed as part of QuickTime 5.0.2 and earlier >versions. Consequently, Windows customers using these versions of >Explorer who visit your site may be unable to view QuickTime content >in the browser. To mitigate this problem and to ensure a positive >experience for your Web site visitors, you should add to your site >the HTML code that makes available the new ActiveX control for >QuickTime, as described below. > >NOTE: THIS ISSUE AFFECTS ONLY USERS OF INTERNET EXPLORER ON WINDOWS. > >BACKGROUND >QuickTime uses a plug-in mechanism to display movies from your Web >page in the user's browser. Before, you would use an EMBED element >alone to display QuickTime content within the browser, much like in >the example below: > ><EMBED src="sample.mov" width="160" height="144" autoplay="true" >CONTROLLER="false" >PLUGINSPAGE="http://www.apple.com/quicktime/download/"> </EMBED> > >For this mechanism to work, the user must have the QuickTime plug-in >installed on his or her system. If the appropriate QuickTime plug-in >is not installed, when your HTML page with QuickTime content is >loaded into the user's browser, the movie is not visible. Instead, >the browser replaces it with a "broken plug-in icon" and attempts to >assist the user in obtaining the required software. An unfortunate >side effect of this approach is that the user is directed away from >your site and is distracted by the installation process. > >THE ISSUE >Until recently, the plug-in installed as part of QuickTime worked >for both Netscape browsers and Microsoft Internet Explorer on both >Windows and Mac OS. Now Windows users who try to play a QuickTime >movie in Internet Explorer version 5.5 SP2 or later will encounter >the "broken plug-in icon" until they install the new QuickTime >ActiveX control from Apple in addition to the QuickTime plug-in. >Users of other browsers on either Windows or Mac OS are >unaffected--they can continue to use the plug-in installed with >QuickTime and do not need to get the new QuickTime ActiveX control. > >Once users have the new ActiveX control installed, they are also >unaffected; they can also view existing pages. > >THE SOLUTION >When authoring web pages, you can easily prevent this problem by >authoring your HTML to check that the required ActiveX control is >installed wherever you have QuickTime content embedded. This HTML >change will result in web pages compatible with Netscape and >Internet Explorer browsers on both Mac and Windows systems (see >below for more information). > >The required code consists of an HTML OBJECT element with an >enclosed EMBED element as in the following example: > ><OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" >width="160" height="144" >CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab"> ><param name="src" value="sample.mov"> ><param name="autoplay" value="true"> ><param name="controller" value="false"> ><embed src="sample.mov" width="160" height="144" autoplay="true" >CONTROLLER="false" >PLUGINSPAGE="http://www.apple.com/quicktime/download/"></EMBED> ></OBJECT> > >CLASSID must always equal: >clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B >CODEBASE must always equal: >http://www.apple.com/qtactivex/qtplugin.cab >PLUGINSPAGE must always equal: >http://www.apple.com/quicktime/download/ > >The other attributes should be customized to your web page. You need >to substitute "sample.mov" (in both SRC attribute elements) with the >URL of the actual movie to be played. You should also change the >HEIGHT and WIDTH parameters to match the height and width of the >movie (in pixels). > >If you already have EMBED elements for the QuickTime plug-in on the >relevant pages, you need to enclose each of them in an OBJECT >element with CLASSID and CODEBASE parameter values as shown above >and with SRC and other parameter values to match those in your >existing EMBED element. The OBJECT element can use any EMBED >attributes QuickTime understands. Visit >http://www.apple.com/quicktime/authoring/embed.html for more >information. > >For existing web pages, it may be sufficient to add such an OBJECT >element to the "front door" page of your site. Once the OBJECT >element on the "front door" page has caused the user to install the >ActiveX control, all subsequent pages with the original EMBED >elements will work properly. In cases where you cannot be certain >that the "front door" page is always visited, then all your pages >should be revised to use these OBJECT elements. > >HOW IT WORKS >The OBJECT element is used by Internet Explorer on Windows >9x/NT/2000/XP platforms and by other browsers that support the >QuickTime ActiveX control. The enclosed EMBED element is used by >Netscape browsers, Internet Explorer for the Mac, and other browsers >that support the "Netscape style" QuickTime plug-in. Browsers that >understand the OBJECT element ignore the EMBED element; those that >don't understand the OBJECT element use the EMBED element. > >Within the OBJECT element, the CLASSID parameter uniquely identifies >which ActiveX control to use. A CLASSID parameter with the value >"clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" tells Internet Explorer >to use the QuickTime ActiveX control. (You must use exactly this >value; it is the only value that identifies the QuickTime ActiveX >control). If the user does not already have the ActiveX control >installed on his or her system, the CODEBASE parameter tells the >browser where to find it for downloading. Internet Explorer will >automatically offer to download and install the ActiveX control for >the user, after which the movie can be played without restarting the >browser, or, if QuickTime is not already installed, will prompt the >user to download and install QuickTime. You must always use >"http://www.apple.com/qtactivex/qtplugin.cab" for the CODEBASE URL. >This URL will always have the latest version of the QuickTime >ActiveX control. >Because a browser will use either the OBJECT element or the EMBED >element, but not both, most of the element attributes must be >included in each. Note that in the example above the EMBED element >has autoplay="true" and the OBJECT element has <param >name="autoplay" value="true">, so the movie will begin to play >automatically whether it is loaded with the QuickTime ActiveX >control or the QuickTime plug-in. The only attributes that should >not be duplicated are CLASSID, CODEBASE, and PLUGINSPAGE. CLASSID >and CODEBASE are specific to the OBJECT element. PLUGINSPAGE is >specific to the EMBED element. > >Although Windows Internet Explorer 5.5 SP2 and 6.0 will no longer >use the QuickTime plug-in, once the QuickTime ActiveX control has >been installed on a user's system, these versions of Internet >Explorer will use the installed ActiveX control to satisfy a >properly coded EMBED element. > >ADDITIONAL READING > >For more information on the OBJECT element, see: > * The W3C Web site at > http://www.w3.org/TR/REC-html40/struct/objects.html#edef-OBJECT > >For more information on HTML in general, see: > * HTML & XHTML: The Definitive Guide 4th Edition, > by Chuck Musciano & Bill Kennedy, published by O'Reilly. > * Dynamic HTML: The Definitive Reference, by Danny Goodman, > published by O'Reilly. > >For more information about QuickTime on Web sites, see: >QuickTime for the Web, published by Morgan Kaufmann Publishers. ><http://developer.apple.com/techpubs/quicktime/qtdevdocs/QT4WebPage/QT4WebBo…. >htm> > >For more information on Internet development, see: >http://developer.apple.com/internet/ > >Disclaimer: >IMPORTANT: This Apple software is supplied to you by Apple >Computer, Inc.

Symposium on descriptors
by Wendy Warr 29 Oct '01

29 Oct '01

I am posting this message at the request of Bryan Vickery bryan.vickery(a)chemweb.com Dear Colleague, Division of Chemical Information (CINF) of the American Chemical Society (ACS) and the Chemical Structure Association (CSA). ACS National Meeting, Orlando - April 7-11, 2002. ___________________________________________________________________ Molecular Descriptors for Diversity Analysis, Library Design and Virtual Screening Many methods have been devised to study the similarity, or dissimilarity, of compounds; to predict physicochemical properties; to identify compounds with desirable or "drug-like" properties; and to select activity-enriched sets of molecules from "virtual" libraries (i.e., from large numbers of synthetically feasible compounds). At the root of all these methods are descriptors used to characterize the molecules. These include various types of molecular fingerprints, 3D pharmacophores, physicochemical properties, electrotopological states and connectivity indices. Some represent 2D molecules; some handle 3D ones. Some are "meaningful" to medicinal chemists; some are not. This symposium will examine the nature of such descriptors and the extent to which they have been successfully implemented. ___________________________________________________________________ Abstracts should be submitted via the OASys: ACS Online Abstract Submittal System. http://oasys.acs.org/acs/223nm/cinf/papers/index.cgi The deadline has been extended into early November 2001 but do not delay. Full instructions are given at the ACS site, but you should select the option for "Chemical Descriptors" Then follow the instructions for adding title, authors and text. If you have any questions about this session please do not hesitate to contact me, Regards, Bryan Bryan Vickery Commercial Director ChemWeb, Inc. 84 Theobalds Road London, WC1X 8RR United Kingdom E: bryan.vickery(a)chemweb.com T: + 44 (0)20 7611 4424 F: + 44 (0)20 7611 4301 W: www.chemweb.com Dr. Wendy A.

Chemistry thesaurus
by Simone JEROME 17 Oct '01

17 Oct '01

I used CAS Vocabulary helper as an aid to catalogue books in the library. Formerly I used the index guide and the subject index of CA. Unfortunately in june, the vocabulary helper was withdrawn. I had only two solutions none of which satisfies me. Either I go back to my old manual practice (time-consuming) or I look for another thesaurus (but which and moreover the work already done is lost). I contacted CAS without great success as they directed me to the Lexikon on STN. I do not need a search aid more specially as it is not entirely free and the application is far from being a must. I suppose that other chemistry librarians encounter the same kind of problem. Looking on the Web to find another thesaurus, I have found the same request dated back to 1997 on Chemweb. It was rather amusing that somebody from CAS answered and encouraged the requester to use... the Vocabulary Search Helper. Help !

Michael, As far as I am aware, Version 2.6 SP3 works fine with IE 5.5 SP2. I believe support for IE 6.0 will follow.
