Try:

Shell "rundll32.exe url.dll,FileProtocolHandler C:\WINDOWS\Help\access.chm", vbNormalFocus

change C:\WINDOWS\Help\access.chm to the path/filename you need.

A start to get the file up, I have code somewhere to specify but cannot look now, will check after lunch.

Found code faster than I thought I would

This code works with .hlp files, try it with the .chm files and see if it works. Not sure, but worth a shot.

'WINHELP DECLARATION
Public Declare Function WinHelp Lib "user32" Alias "WinHelpA" _
(ByVal HWND As Long, ByVal lpHelpFile As String, _
ByVal wCommand As Long, ByVal dwData As Long) As Long

Public Const HELP_CONTENTS = 3
Public Const HELP_FINDER = 11

'IN A MODULE

Public Sub ShowHelpContextID(ByVal intHelpFile As Integer, lngContextID As Long)

    ' Open the help file using the
    ' HELP_CONTEXT constant (1)

WinHelp App.hInstance, SetHelpStrings(intHelpFile), 1, lngContextID

End Sub

Public Function SetHelpStrings(ByVal intSelHelpFile As Integer) As String

    ' Set the string variable to
    ' include the application path

Select Case intSelHelpFile

        Case 1
            SetHelpStrings = App.Path & "\Res\Backup.hlp"

        Case 2
            ' Place other Help file paths in successive Case statements
            SetHelpStrings = App.Path & "\Res\Restore.hlp"

    End Select

End Function

Hi Mr. Den,

Thanks for your input

@ first i had tried out the CJ way using this code. The help shows but i cannot show a specific page using the helpcontext command

      With CommonDialog
        .HelpFile = App.Path & "\somehelp.chm"
        .DialogStyle = 1
        .helpcommand = 1
        .HelpContext = 1001
        .Flags = 0
        .showhelp
      End With

For API I was using

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

which works for for both chm and winhelp.

My main interest was on how i can navigate to a specific page on the help.

regards,

Using the code I gave you above:

Adding to the declarations:

    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

I change this line:

WinHelp App.hInstance, SetHelpStrings(intHelpFile), 1, lngContextID

to:

HtmlHelp App.hInstance, SetHelpStrings(intHelpFile), 1, lngContextID

And the code works properly for .hlp files, have you tried that on a .chm file?
