CHM files are designed to run on their own and not in a form. Atleast I do not know of any control that you can use to display a CHM file in a VFP form. What you can do is use the Microsoft Browser ActiveX control in a form and pass the default HTML page used to create your CHM file to the Navigate2 method of the control.
