Microsoft Help allows the user to search through .HLP files in a variety of ways. In order to use Microsoft Help in your application, you must create one or more .HLP files. To do this, you need a program that converts text files into help files. This is called a help compiler. You can find a help compiler (called hc) and instructions on its use in the Microsoft Windows SDK. You will also find information on how to construct the text files that get compiled into help files.
