If you have a compiled help file (.chm), your tools can reference it. A compiled help file is used when viewing the tool reference page.
By providing the help context ID (the HTML topic ID), when the user right-clicks a tool and clicks Help, the help topic associated with the help context ID in the .chm file appears.
If you do not supply a help context ID or supply an incorrect one, the .chm file default page appears.
There are many sources of information for creating and compiling HTML help or .chm files. A good starting point is the Microsoft HTML Help 1.4 SDK topic available from the Microsoft library (https://msdn.microsoft.com). In the library, you'll also find information on creating and compiling .chm files listed under Visual Tools and Languages, HTML Help.
- Right-click the tool and click Properties.
- Click the Help tab.
- Check Reference a compiled help (CHM) file for the tool help.
- Browse to the location of the .chm file, select it, and click Open.
- In the Properties window, enter a help context ID that corresponds to the topic in the .chm file.
- Click OK.
