How can I open a help file (chm or so) from my GUI developed in VC++ 2008?

Question

Hi,

I'm trying to add some help to my GUI developed in VC++ 2008. I want to compile a chm file, or a hlp file that can be accessed from my menu. Anyone can give me any idea about how to do this?

Thanks a lot

Answer 1

Sorry, I misunderstood your question earlier.

For opening the Help file, you can use WinHelp

There are some issues with WinHelp in Windows Vista and Win2K8, For details on how to deal with them, Look here

Answer 2

You could just ShellExecute the .chm file. That will open it.

Answer 3

If you are using managed C++:

In the namespace

System.Windows.Forms

you can find the class Help with static methods ShowHelp, ShopHelpIndex

If you are using unmanaged C++ (WIN32 api):

You can just launch the *.chm file. Example how to do it you can find here: http://stackoverflow.com/questions/42531/how-do-i-call-createprocess-in-c-to-launch-a-windows-executable . Or here http://www.codeproject.com/KB/system/newbiespawn.aspx

Under HKLM\Software\Microsoft\Windows\HTMLHelp , create an entry
named help.chm
value C:\path to\help file.chm

Then to open the chm at a particular topic call

 HtmlHelp(m_hWnd, "Help.chm", HH_DISPLAY_TOPIC, NULL);
