Using your Web browser for online help

This page describes the requirements for using your Web browser to view online help for TreeView, and how to configure TreeView as a helper application.

While the help pages can be viewed at any time using your browser, if you want to call up the help topics from within TreeView then you will need to ensure your browser is correctly set up. This is usually straightforward and, under Windows at least, may already have been done for you when TreeView was installed.

Configuring TreeView as a helper

System requirements

Apple Macintosh

You must have Internet Config installed and configured on your machine in order for TreeView's online help to work.

Internet Config

Internet Config is a freeware system extension that allows applications to share the same preferences. You can add your e-mail address, news information, and Helper configuration information into Internet Config once, instead of in each of your Internet applications. Applications that are Internet Config aware include Microsoft Internet Explorer, among others. You can download Internet Config 1.3 from this site.

Setting up Internet Config for online help

Once you have Internet Config installed you need to ensure that your Web browser is listed as your "http" helper in Internet Config's settings. To do this follow these steps:

1. Click on the Helpers button in the Internet Preferences dialog.

2. In the Helpers dialog box set the http helper to your browser by clicking the Add button. Once you've added your browser you should see something like this:

3. Quit Internet Config, remembering to save your settings.

When you start TreeView the program will use Internet Config's settings to locate your Web browser, and will communicate with your browser via the Internet Config extension.


Under Windows 95/NT TreeView should automatically find your browser using the systems's registry database. If it does not then check that your browser is correctly installed. Under Windows 3.1 TreeView will only be able to detect Netscape Navigator or Microsoft Internet Explorer. Note that under Windows 3.1 you must have Internet Explorer 2.01 or later; earlier versions will not work correctly.

Configuring your browser to view TreeView files

To configure your browser to view TreeView files, such as those available from the Example tree file page, you need to associate files with the MIME type "application/x-treeview" and extension ".tre" with TreeView. On first encountering a TreeView file your browser may prompt you for instructions on how to handle TreeView files. If it does not, follow these instructions.

Netscape Navigator

Use the General Preferences command under the Options menu to install TreeView as a helper.

Microsoft Internet Explorer

Under Windows Internet Explorer should know how to handle TreeView files automatically. On the Macintosh you can configure the browser using either Internet Config file mapping settings, or the Internet Explorer's Options command.
