A late answer but anyway I hope it answers your question!
I simply let the explorer decide what to do with the file. If the file 
extension is recognised the document will be opened by the registered 
program.

;-----------------------------------------------------------------------
------------------
;simply throw a document to the explorer and let the explorer decide 
what to do with it
method OpenDocument(sDocFile String)
var
	sExeCommand String ;command to execute
endVar

;add " (double quote) to start and end of DocFile name to allow for 
spaces in filename
sExeCommand = "Explorer \"" + sDocFile + "\""
;sExeCommand.view()

;execute(command,wait): wait = True -> wait for explorer to close to 
avoid annoying issues
;when opening for instance multiple instances of Excel using the same 
personal.xls

;Errortraponwarnings(yes)
try
	execute(sExeCommand, True)
onFail
	errorShow()
endTry
;Errortraponwarnings(no)

endMethod
