Open a Url

As far as I know, no application would be able to interact with the cookies or JavaScript in a browser once it has launched. This is a security feature of web browsers.

But what you could do, is when a user clicks a "Close" button in your Maplet, have the Maplet open a url in the browser that indicates the Maplet has completed. Your web application would then be able to read a cookie that your page set before launching the Maplet to identify the user and then continue with whatever server-side code you would like.

Specify a callback

DuncanA — Wed, 20 Oct 2010 03:11:08 Z

According to the MapleNet documentation it is possible to specify a callback in the html file, i.e., "a JavaScript function to invoke when the Maplet Shutdown command is invoked." See Listing 6 and Table 4 on http://www.maplesoft.com/documentation_center/maplenet/Publisher/MapleNet%20HTML-4-1.html

thanks, update, and a new question

Doug Meade — Wed, 20 Oct 2010 10:09:34 Z

Thanks Duncan and Will, these are helpful.

I have confirmed that Maple's system (and ssystem) commands can launch a webpage in the default browswer. For example:

Windows:  ssystem( "start http://www.maplesoft.com/" );
Mac:      ssystem( "open http://www.maplesoft.com/" );

I still have to identify the correct command for UNIX / Linux, but that should not be difficult to find (When I have the time). Within Maple, I can detect the hardware on which Maple from a little proc that I've been using for a few years:

GetVersion:=proc()
  local S, S1, S3, S4;
  options `Copyright 2009, Philip B. Yasskin and Douglas B. Meade, Maplets for Calculus`;
  uses StringTools;
  S:=interface(version);
  S:=map( Trim, Split( S, "," ) );
  S3:=Split(S[3], " " );
  sprintf("%s (%s)", S[2],S3[-1]);
end proc:

GetVersion();
                       "Maple 14.00 (XP)"

Since the MapleNet server can serve a Maple worksheet file, I wonder if there is a way - within Maple - to determine if a worksheet is being run with a local copy of Maple or served over the internet with MapleNet?
