To display your own icon instead of the standard Help icon when users minimize the Help window with your Help file open, you can include the ICON option in the [OPTIONS] section of the Help project file:
ICON=icon-file
Icon-file is the name of an icon file you have created with the Microsoft Windows Icon Editor or a similar tool. It can be an absolute path or a path relative to the Help project directory.
For example, the following entry in the Help project file uses a custom icon:
[OPTIONS]
ICON=hyper.ico
This icon appears when the Help window is minimized, as shown in Figure 13.7.
For more information abuot project file options, see Chapter 16, “The Help Project File.”
