Providing context-sensitive help in an application can save users
time trying to find information instead of making them navigate through a Help
Contents page or an Index.
Context-sensitive help gets the
user to the required information quickly and
directly by being "aware" of which
control has focus when the user presses F1.
The following sections discuss three easy ways to add contextsensitive
help to your application:
HelpContextID Help. This type of help uses the traditional F1 key
to show help information to a user.
ToolTips. This type of help shows brief messages to the user when
the mouse pauses over an object.
WhatsThisHelp. This type of help uses the WhatsThis icon to let users query the
meaning of an object.
NOTE : VB Uses WinHelp and HTML Help Files Identically. When you
implement context-sensitive help as described in the following sections, you don't need
to worry about whether the project's Help file is a WinHelp or an HTML Help file: both file
types furnish Topic IDs for their help topics, and the VB programmer uses the two different file
types in exactly the same way to provide context-sensitive help, as described below.
