hhctrl.ocx, hh.exe and Ctrl/F

[trevors_decoy]

Hi,

my Delphi app displays help (stored in a .CHM file) by calling the
hhctrl.ocx HtmlHelpA() function:
First with HH_INITIALIZE (passing NULL as the caller window)
Then with HH_DISPLAY_TOPIC
This creates and displays a window with the requested topic, as
expected. However, in the right-hand pane of this window, I cannot use
Ctrl/F to search for a piece of text *within* the displayed topic - the
Ctrl/F is ignored.

As an alternative, I can display the required help topic by calling
CreateProcess() to launch HH.EXE. This also displays the requested
topic, and in this window Ctfl/F works just fine.
However, launching HH.EXE creates a new window each time - it doesn't
reuse an existing window if one is showing, like HtmlHelp() does.

Is there any way of displaying a topic stored in a .CHM file that takes
notice of Ctrl/F, and also reuses an existing htmlhelp window if one is
already showing?

Hello Trevor,

I'm not a Delphi programmer but tried from command line and get secondary
window like your CreateProcess() call:
HH.EXE -mapid 10010 ms-its:C:/_working/CHM-example.chm
download example from:
http://www.help-info.de/en/Help_Info_HTMLHelp/hh.htm

The CTRL+F is not working for me in the way you described.
AFAIK - this is only working if you click the topic pane *first* and then
press CTRL+F.

Is this a difference in the two cases you described - means you click *or
not* click the topic first?

Post again and I'll try HH_DISPLAY_TOPIC later for VB6 or VB2005 calls.

You know there is a "Search" (in German "Suchen") tab like shown in this
sample:
