How do I open a compiled Help File

[AccessGuruCarl]

I've created a help file using Microsoft HTML HELP Workshop (compiler for .CHM files)

I've placed a button on the form, but when I try open the help file I get error message Invalid Procedure call or
argument.

Here is the code being used.

Dim stAppName As String

stAppName = "C:\Dev\EDI-Help.chm"
Call Shell(stAppName, 1)

I think I need an API call here, any idea's on how to make this work. Once I get it working I'll replace the default F1 key with this help file.

Thanks in advance,
Carl

What I got from the Help Help when I was creating a help file is:

Private Sub CmdHelp_Click()
    Dim strPath As String
    
    ' Get path to current database.
    strPath = CurrentProject.Path
       
    ' Display help for this form in an external tripane window,
    ' using sibling mode.
    Call HTMLHelp(0, strPath & "\help\JrnlHelp.chm" & ">MSO_small", HH_HELP_CONTEXT, ByVal 2010&)
        
End Sub

And

' Declarations for calling the HtmlHelp API.
' Simplified version of module from HTML Help Authoring Kit.
'
Option Explicit

' Commands to pass to the HtmlHelp function.

Enum HH_COMMAND
    HH_DISPLAY_TOPIC = &H0
    HH_HELP_FINDER = &H0           ' WinHelp equivalent.
    HH_DISPLAY_TOC = &H1           ' Not currently implemented.
    HH_DISPLAY_INDEX = &H2         ' Not currently implemented.
    HH_DISPLAY_SEARCH = &H3        ' Not currently implemented.
    HH_SET_WIN_TYPE = &H4
    HH_GET_WIN_TYPE = &H5
    HH_GET_WIN_HANDLE = &H6
    HH_GET_INFO_TYPES = &H7        ' Not currently implemented.
    HH_SET_INFO_TYPES = &H8        ' Not currently implemented.
    HH_SYNC = &H9
    HH_ADD_NAV_UI = &HA            ' Not currently implemented.
    HH_ADD_BUTTON = &HB            ' Not currently implemented.
    HH_GETBROWSER_APP = &HC        ' Not currently implemented.
    HH_KEYWORD_LOOKUP = &HD
    HH_DISPLAY_TEXT_POPUP = &HE    ' Display string resource ID or text in a pop-up window.
    HH_HELP_CONTEXT = &HF          ' Display mapped numeric value in dwData.
    HH_TP_HELP_CONTEXTMENU = &H10  ' Text pop-up help, same as WinHelp HELP_CONTEXTMENU.
    HH_TP_HELP_WM_HELP = &H11      ' Text pop-up help, same as WinHelp HELP_WM_HELP.
    HH_CLOSE_ALL = &H12            ' Close all windows opened directly or indirectly by the caller.
    HH_ALINK_LOOKUP = &H13         ' ALink version of HH_KEYWORD_LOOKUP.
End Enum

Declare Function HTMLHelp Lib "hhctrl.ocx" Alias "HtmlHelpA" _

Hello Remou,

I've implemented the code, I'm getting this error message.

HH_HELP_CONTEXT called without a [MAP] section.

Any Idea's


Thanks

Its been a while, This may help:

http://www.codeguru.com/cpp/w-p/help/html/article.php/c6513/

Toward the end of the article there is mention of the above error.

 

[AccessGuruCarl]

Thanks for the post.

I was able to fix that error using code below.

Call HTMLHelp(0, strPath & "\EDI-Help.chm" & ">MSO_small", HH_DISPLAY_INDEX, ByVal 2010&)


Now I get error for:
The window named "MSO_small" passed to HH_GET_WIN_TYPE as not been specified.

I'll check your link for further details, if you have an idea how to fix, please post.

Thanks again,
Carl

You may consider 2 alternate ways, either
FollowHyperlink stAppName ' may lunch a security dialog box
or
CreateObject("WScript.Shell").Run stAppName

Hope This Helps, PH.
