How to attach/include a .chm file to the Click function on a Help->Topics menu?


I have a small app, and I have a menu that has Help as an option.  Clicking on Help, you get the About option and a Help Topics option.
When the user clicks on the Help Topics option, I want the myHelp.chm file to be launched (it's MS HTML Help) in it's own little window (as normally happens).

'Declare API
Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long

'Call it
Public Function OpenHelpFile()
   Dim lngRetVal
   Dim strLocation
   strLocation = app.path & "myHelp.chm" 'Here you put the path to your chm
   lngRetVal = ShellExecute(me.hwnd,"open",strLocation,vbnullString,vbNullString,vbNullString)
   if lngRetVal > 53    
        msgbox "Failure Attempting to Open Help File!"
   end if
End Function

give that a try....


try this:

You could also set the help file at load time and if the user presses F1 it will start it up automatically:
App.HelpFile = App.Path & "\Help.chm"


Help menu item (click event):
SendKeys "{F1}", False
