① Define API:
Function Long HtmlHelpA (long hwnd, string lpHelpFile, long wCommand, string dwData) Library "hhctrl. ocx"

Parentwindow. triggerevent ("ue_help ")

③ Custom Event ("ue_help") script in the MDI form:

For example, the name of the chmhelp file is help.chm, and the main window name of help.chmis main. the page to be tuned is my.htm, and the script is:
HtmlHelpA (handle (this), "help. chm> main", 0, "my.htm ")
