WinHelp Appearance and Features

Depending on how it has launched and what settings the Help author chose, a WinHelp file opens either to its default topic, its table of contents, or its index.

A topic in a WinHelp file opens in a separate window, in a size and initial position that the Help author may choose. Users can resize or reposition the window. The Help author can control whether the Help file stores the user's settings between sessions, or always opens in the default size and position.

When a topic is open, a title bar at the top of the Help window displays the topic title. Below that is a row of menus (File, Edit, Bookmark, Options, and Help), which control various aspects of the file. A row of buttons usually appears below the menus. The Help author controls which buttons, if any, appear. Typical buttons include Contents, Index, Back, and Print, along with << and >> buttons to browse through the file. Help authors can also create custom buttons to jump to specific topics or perform other actions.

Below the buttons is the main text area of the window. Typically, the text begins with a heading, often bold or in a larger font than the rest of the text. This heading may sometimes be in a non-scrolling region—an area of the window that does not move up or down via the scrollbar at the side of the window. Non-scrolling regions can only be used at the beginning of a topic. The Help author can control size and background color of a non-scrolling region.

Help authors can also control the background color of the main text area, where the actual text of the topic appears. This text can be formatted and arranged in many ways. Within the text, jumps appear as green text with a single underline. Single-clicking on a jump opens a different topic. Some jumps may open secondary Help windows to display information. Popups appear in the text as green text with a dotted underline. Single-clicking on a popup opens a small window with no menus, buttons, or scrollbars, sized to fit the text. Often, popups provide short definitions of key terms or other supplemental information about the main text. The popup automatically disappears the next time the user clicks or presses a key.

Many, though not all Help topics have See Also jumps at the end of the text. Depending on the Help author's preference, this feature may be a simple list of jumps under the heading See Also, or it may be a small button that, when clicked, brings up a dialog box displaying all the relevant topics. Clicking on the name of a topic in that dialog box then clicking Display opens that topic.

Most Help files also contain a table of contents and an index to help users locate information. These appear in a separate, tabbed window. Clicking on the Contents tab opens the table of contents, in which users can click on headings to see the topics. Often, headings are marked with icons that look like small books and the topics have icons that look like pages. Double-clicking on a topic (or clicking on a topic then clicking Display) opens that topic. Clicking on the Index tab opens the index, which has a typing field and an alphabetical keyword list. Typing in the typing field automatically scrolls the list of keywords to the closest match. Double-clicking on a keyword (or clicking on a keyword then clicking Display) displays the topic associated with that keyword (if only one) or brings up a list of all topics associated with it. The index is important in helping users locate information. Sometimes Help files also have a Find tab, which lets the user search for any word used in the text of the file, not just for keywords.

WinHelp also supports a feature known as context-sensitive help. Context-sensitive help is assistance that is appropriate to where the user is in the software application, and what they are trying to do.

A rather security critical feature is that one can also include a DLL file containing custom code and associating it with WinHelp topics. Effectively this makes .HLP files equivalent to executables.
