hhctrl.ocx HtmlHelpA not working

[Rich]

In VB6, I'm having a problem loading a .chm file using the API.

If you press F1, the help file will load. But it will NOT load if you
call the API, until after you have pressed F1... its like it isn't being
initialized until you hit F1. And I even tried LoadLibrary but that
still doesn't work.

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

Public Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA"_
(ByVal lpLibFileName As String) As Long

try to get work the following module:

Do you want to press first F1 by the user and then click a button to call
help?

Hi Rich,

API calls are case-sensitive in VB, and LoadLibrary doesn't work at all.
Here's all you need:

Private 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

You may want to download my HTML Help class module
(http://www.mvps.org/htmlhelpcenter/htmlhelp/hhvbclas.html). It contains all
the most-used functions.
