Integrating HTML Help with VB5

[J Westcot]

Hi All:

Well, the Subject pretty much says it all -- I would like to know if HTML-based Help can be integrated into VB5 and, if so, how do I do it? It's pretty easy to hook into standard .HLP files in VB5, but I haven't a CLUE (or the requisite documentation!) about hooking into HTML-based Help.

Please, someone, shed some light on this burning issue!

Thanks!

You could ShellExecute the html file from vb and will be shown in default browser

True, I could certainly shell out, but how would that get me to the appropriate help topic? Is there no way to integrate this "new and improved" help system with VB5?

Try these:

Public Const HH_DISPLAY_TOPIC = &H0
Const HH_SET_WIN_TYPE = &H4
Const HH_GET_WIN_TYPE = &H5
Const HH_GET_WIN_HANDLE = &H6
Const HH_DISPLAY_TEXT_POPUP = &HE
Const HH_HELP_CONTEXT = &HF
Const HH_TP_HELP_CONTEXTMENU = &H10
Const HH_TP_WM_HELP_MENU = &H11

Declare Function HtmlHelp1 Lib "hhctrl.ocx" Alias "HtmlHelpA" (ByVal hwndCaller As Long, _
                 ByVal pszFile As String, ByVal uCommand As Long, ByVal dwData As Long) As Long
                 
Declare Function HtmlHelp2 Lib "hhctrl.ocx" Alias "HtmlHelpA" (ByVal hwndCaller As Long, _
                 ByVal pszFile As String, ByVal uCommand As Long, ByVal dwData As String) As Long

retrn = HtmlHelp1(0, "C:\Temp\Help.chm", HH_DISPLAY_TOPIC, 0)
retrn = HtmlHelp2(0, "C:\Temp\Help.chm", HH_DISPLAY_TOPIC, "My_Help.htm")

These let you call a compiled HTML help files and display a topic using either a reference number (htmlhelp1) or using the name of a file (htmlhelp2)

Hope it helps

Thanks, Dan -- that seems to be EXACTLY what I need! (Oh, if only I'd looked at the MSDN Library first, I could have spared everyone my stupid question . . . .)
