How to import files into Access using Open File Dialog Box Option

Hi Experts,
I am trying to find a way to import Excel or Text files into access but giving the user the option to import the files from any location like the open file dialog box.  I looked for it in this forum and found few of them but nothing has worked for me.  Note, i am using Access 2007.  Anyway, i found the code below and it works for me but need your help with little bit tweaking.  Here is what i need:
1) i want to be able to import either Excel, Text or CSV files.  The code below only imports access db
2) i am not sure where i put the code that handles the import function because the code is so complicated and could not follow it.  The code below only gives you the browsing capabilities
3)I would like to get rid off any other code of lines that is not serving my purpose which is only import Excel type file or text/csv type files.  By removing the extra codes will simplify the code for me and i would be able to follow it or make changes.
thanks
