Hi everyone,

I need some help on creating help files for an application made i
excel (and VBA). Any leads....

maybe something like a windows help file. I know a little about .ch
files, but nothing about creating windows help files.

You can use HTML help files in an Excel application.

To invoke them, use some code like


Declare Function HtmlHelp Lib "hhctrl.ocx" _
Alias "HtmlHelpA" _
(ByVal hWnd As Long, _
ByVal lpHelpFile As String, _
ByVal wCommand As Long, _
ByVal dwData As Long) As Long

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 ' Display string resource ID or text in
a pop-up window.
Const HH_HELP_CONTEXT = &HF ' Display mapped numeric value in
dwData.
Const HH_TP_HELP_CONTEXTMENU = &H10 ' Text pop-up help, similar to WinHelp's
HELP_CONTEXTMENU.
Const HH_TP_HELP_WM_HELP = &H11 ' text pop-up help, similar to WinHelp's
HELP_WM_HELP.


Public Sub OpenHelp(ByVal ContextId As Long)
Dim hwndHelp As Long
'The return value is the window handle of the created help window.
Dim hwndHH
hwndHH = HtmlHelp(0, ThisWorkbook.Path & "\" & AppId & ".chm",
HH_HELP_CONTEXT, ContextId)
End Sub

where ContextId is defined in the HTML help file creation , and AppId is the
application name (assuming that is used for your help file).

Thanks Bob,

When I tried to run your code, I get a runtime error '453': Can't fin
DLL entry point HtmlHelp in hhctrl.ocx

Is it something to do with the contextId that is passed to th
function.


By the way, I tried the following piece of code, but my excel shee
crashes when I run it.

''''''''''''''''' code starts here ''''''''''''''''''''''

Const HH_DISPLAY_TOPIC = &H0

Declare Function HtmlHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" ()

Sub DisplayHTMLHelp()
Dim hwndHelp As Long
hwndHelp = HtmlHelp(0, "C:\WM.chm", HH_DISPLAY_TOPIC, 0)
End Sub

''''''''''''''''' code ends here ''''''''''''''''''''''

Any idea...!!!

There was no bug in your code. I am using it nicely now. Somehow whil
trying to use it I must have commented a part and sometimes the fil
used to crash or sometimes i used to get the above error I mentioned.

But after uncommenting that part, it started working perfectly.

The bug that I introduced was:

I had empty brackets instead of the following

(ByVal hWnd As Long, _
ByVal lpHelpFile As String, _
ByVal wCommand As Long, _
ByVal dwData As Long)

That's one of the problems with APIs, if you get the call wrong, it crashes
spectacularly.
