I just tried these things:

Old 16bit help files:
c:\cpp\borlandc\bin> start shed.hlp
works.
c:\cpp\borlandc\bin> winhelp shed.hlp
works.
c:\cpp\borlandc\bin> winhlp32 shed.hlp
works.

Newer 32bit help files:
c:\cpp\bcc55\help> start bcb5.hlp
works.
c:\cpp\bcc55\help> winhelp bcb5.hlp
"This file is not a windows help file"
c:\cpp\bcc55\help> winhlp32 bcb5.hlp
works.

Conclusion:
Execute the help file directly, or use the newer winhlp32.

Try executing hh.exe

hh.exe   MyHelp.html#ThisTopic
hh.exe  MyHelp.chm

or
You could ShellExecute( hwnd, "open", "myhelp.chm", 0,0, SW_SHOW );

.
