It is clear that many of the IBM 4690 POS applications could use an overhaul. But who has the time? And where would one start?

How do I configure graphics files to run under QConnect CE?

The URL/URL2 keywords in the dynakey file pass the URL to Internet Explorer running in one of the two windows on our dialog.  The files passed to IE can be bitmaps, gif files, html files, etc.  Our samples include html files that load bitmap and gif files.  You can essentially show any image in the window that you can show in IE.

There are some limits as size and such that are mentioned below.

Add the URL="...." and/or URL2="...." on a STATE or GROUP line in they dynakey file and that URL will be displayed.  Any file that the URL points to or references must be in the "webCacheDir" on your controller AND be included in the webfiles.lst file in the "webCacheDir".

 

Here are a couple of tibits if you want to make changes or add files etc.:

  1. Keep the number of files in the webfiles.lst to a minimum as they use memory in the terminal.  For example, if you want to replace the bitmap of the NCR flag on Wall Street with an ACME graphic, add your file to the directory, add it to the list and remove the ncrhq.bmp from the list.  You do not have to remove the file from the directory - only the files in the webfiles.lst will be transferred to the terminal.
  2. The sizes of the browser windows are:

    3. Top browser - 632 width x 48 height
    Side browser - 244 width x 414

    Images bigger than these will cause scroll bars to be displayed in the browser windows.

  3. The _xxx.htm files are used to turn off borders and such.  (I do not claim to be an html expert!)
  4. The xxx.htm files handle background colors, sizing etc, and determine which graphic to display.
  5. Internet Explorer for CE only supports JScript - not VBScript.
